The year you sell is the only year this works

Don't lose over $20,000. We'll show you your catch-up super contribution options.

You have sold something, or you are about to, and there is a tax bill coming that is bigger than any you have had before. Somewhere in myGov there is a number called unused concessional contributions that could take a large bite out of it — and nobody in the transaction is paid to mention it.

A licensed adviser will work it out for $2,500 to $6,000, over weeks you may not have. We do it in three minutes — every contribution amount priced, ranked, and shown with the working.

30 second estimate

Three answers for a quick estimate:

$
$
Contribution room $— this financial year
Tax on the table this year $—

A rough guide only. It assumes you have never contributed beyond the compulsory employer amount. The full calculator asks what actually went in, year by year.

If this is you

If you have never heard of this,
that is not your fault.

It is buried in one section of the tax act, shown in myGov as a number with no explanation beside it, and useful in about one year out of ten. Almost nobody is told, and the people around a sale are not paid to say.

"I found out in October. It settled in April."

The accountant does the return months after the year has closed, and by then the contribution can no longer be made. The window shut on 30 June and nobody in the room at the time was thinking about superannuation.

"What is a concessional contribution?"

Concessional. Non-concessional. Total superannuation balance. Notice of intent. Division 293. Every one of them is a real rule with a real figure behind it, written in language nobody outside the industry uses.

"My brother-in-law said just put in the maximum."

Sometimes that is right and often it is not. The last dollars of a large contribution come off a lower tax bracket than the first ones, and above $250,000 of income the fund takes 30% instead of 15%.

"Is it too late? And can I get it back?"

Two different fears. One is a deadline that is real and closer than the calendar suggests. The other is preservation: money that goes into super stays there until a condition of release, and no tax saving changes that.

So we built the thing that was missing.

You type in what you have. We apply the published caps and tax rates, work out every amount you are allowed to contribute, and put them in order on one measure. No appointment, no sales call, no tax file number, and no name unless you want one on the cover.

The ATO won't tell you It holds the figure and shows it in myGov. It does not say what it is worth, which slice expires first, or that this year is the year it is worth most.
Your super fund won't tell you The fund knows what went into your account. It does not know your income, your capital gain or your other accounts, so it cannot work out your cap and does not try.
An adviser will — for $2,500 to $6,000 And for some people that is exactly the right call, because they can give a personal recommendation and take responsibility for it. Most people just need the arithmetic, before 30 June.

Three questions, thirty seconds, and you will know roughly where you stand. It costs nothing.

The loss

Two people. The same sale.
$21,794 apart.

Both sold the same rental for the same gain in the same year, on the same salary, with the same super balance. One of them looked up a number in myGov before 30 June and the other one did not.

Guessed

Dean, 52

  • Sold the unit for a $400,000 gain, less $18,000 of selling costs
  • Never looked at his unused concessional cap
  • Contributed nothing beyond the compulsory employer amount
  • Found out from his accountant in November, five months too late
Tax on the year $114,200
Worked it out

Marcus, 52

  • Same unit, same $400,000 gain, same $18,000 of selling costs
  • $320,000 in super at 30 June, so under the $500,000 line
  • $78,600 of unused cap from five earlier years, plus this year's
  • Contributed $96,700 before 30 June and lodged the notice of intent
Tax on the year $92,406
Same sale. Same rules. One of them paid this much more. $21,794 That is after the fund has taken its 15% on the way in and after Division 293 on the part above $250,000 — it is what Marcus keeps, not what the deduction looks like on paper. $73,045 of his contribution is sitting in his super account. Neither of them did anything wrong. Dean was never shown that there were seven different amounts he could have contributed, and no one involved in his sale had any reason to mention it. The report that stops this being you costs $249.

Dean and Marcus are invented. The arithmetic is not: both figures come from this calculator's own engine on a $400,000 gross gain less $18,000 of selling costs, a $120,000 salary, $14,400 of employer contributions, $320,000 in super at 30 June and five earlier years at the amounts shown on the worked examples page, on the 1 July 2026 caps and rates.

Three dates that change what this costs you

This whole subject runs on 30 June. Miss one of these and the choice is made for you, at a price you did not pick and cannot change back.

30 June

The day the fund has to have the money

A contribution counts in the income year the fund receives it, not the year it is sent. This year's cap is , and the most anyone can contribute with five years behind them is . The paperwork behind it.

The report

The Catch-Up Contribution Report

The free estimate tells you roughly where you stand. This is the part that gives you the actual numbers and puts every contribution amount in order. Twelve sections and thirteen charts, on your own figures, with every working shown so you can check it or argue with it.

Free — tells you there is a decision

  • Your total contribution room this year, worked out from the published caps
  • Whether you pass the $500,000 balance test, and by how much
  • Which rules switch on for you — Division 293, the work test, the discount
  • A band around the tax on the table, and it is a range rather than a figure
  • Every contribution amount named, with what each one means in plain English

What stops the loss — $249

  • The exact tax each amount keeps, to the dollar
  • Every amount ranked, including the ones that keep less
  • Your five unused years pulled apart, each with the 30 June it goes
  • The amount that lands exactly on the top of each tax bracket
  • The Division 293 slice, and why the last dollars cost half what the first ones do
  • The balance test run again for next year, with your contribution counted in it
  • The assistant, on your own figures, with no limit
  • The whole thing as a PDF you can print, charts included

How it works

Catch-up super contributions in three steps

If you can read a super statement, you can use this. Simple mode asks seven short steps. Advanced adds selling costs, capital losses, salary sacrifice and next year's income.

01

Tell us what you have

Your super balance at the last 30 June, your age, what went in during each of the five earlier years, this year's income and the gain. We do not ask for your name, your tax file number, your member number or your myGov login, and we never will.

02

See where you stand, free

Your total contribution room, whether you pass the $500,000 test, which rules switch on for you, every amount you could contribute named in plain English, and a band around what the whole thing is worth.

03

Find the amount before 30 June

$249 opens the full report: every amount priced to the dollar and put in order, so the expensive mistake is obvious before the year closes. PDF included, ready to send to your accountant.

Built on section 291-20 of the ITAA 1997

The carry-forward rule itself, the balance test in subsection (3), the ATO's published contribution caps, and the individual income tax rates for 2026-27.

Every working shown

Nothing is a black box. Every figure in the report carries the arithmetic that produced it, down to which tax bracket each slice of the deduction came off.

Not advice, and we say so

We are not licensed to tell you how much to contribute, and the arithmetic is the part people are missing anyway — not the opinion.

Refunded if it does not fit

If the report does not apply to your circumstances, tell us what went wrong within 14 days and it is refunded in full.

Included with the report

And if you do not follow something,
just ask it.

Every report comes with an assistant that has read your report — your figures, your unused years, your numbers — and answers questions about it in plain English. Not a search box and not a help page. It knows what your report says because it has been given it.

Ask Agent
What is Division 293 in normal words?
An extra 15% the fund pays on contributions once your income plus your contributions passes $250,000. It means the fund takes 30% instead of 15%. Your income plus employer contributions is $314,160, so it passes by $64,160 — and on this report it costs $7,500 more than contributing nothing would.
So is it worth contributing at all?
That is your call rather than mine, and here is the arithmetic behind it. Division 293 is charged on the lesser of your contributions and that $64,160, so it stops growing once your contributions pass it — which happens at $50,000 of your own money. Below that line each dollar costs 30% and above it each dollar costs 15%, so the last half of your contribution keeps almost twice as much as the first half. That is why the curve in section 05 bends upward instead of flattening.

An example of the kind of answer it gives, on the sample report's figures. Every number in it is on that page.

  • It has your report, not a script Why the top amount is not the biggest one, what Division 293 does to your answer, what happens if you wait until next year. It answers from your own figures and quotes them back.
  • Plain English, on a subject that is anything but It is built for this one subject and told to explain rather than impress — no acronym without the meaning attached, short answers, and no lecture.
  • Entirely optional. Use it or ignore it. It sits behind one button on your report and does nothing until you press it. Nothing in the report is held back from somebody who never opens it, and nothing is sent anywhere unless you ask it something.
  • It is never told who you are What it receives is the figures on your report — amounts, years and categories. Not your name, not your email address, not your account, and never a tax file number, member number or bank detail, because we do not hold those. The name you can put on the report cover is optional and is not part of what it is given.
  • Nothing is kept The conversation stays in your browser tab and is gone when you close it. We record that a question was asked so we know the feature is used — never what it said. Section 5 of the privacy policy sets out exactly what does and does not travel.
  • It explains. It does not advise. It will tell you what the rules say, what each amount keeps and where the figures come from, and it will not tell you how much to contribute — the same line the report itself holds. Nothing here is personal financial advice.

Questions

The questions everyone asks first

Everyone has an annual limit on the super contributions that go in before tax — the concessional cap, $32,500 in 2026-27. Since 1 July 2018, whatever you do not use in a year is carried forward and can be added to a later year's cap. The window is five years, so in 2026-27 the unused amounts from 2021-22 onwards are still there. Somebody who has only ever had employer contributions going in can have a cap of up to $175,000 in one year.

Only somebody whose total superannuation balance was under $500,000 at the 30 June immediately before the year they contribute in. It is a hard line rather than a sliding scale: at $499,999 the whole carried forward amount is available and at $500,000 none of it is. The balance on any other date makes no difference at all, and the test is run again every 30 June.

The deduction comes off your taxable income at your top rate, and the fund pays 15% on the way in, so what you keep is the difference between the two. At the 47% rate that is 32 cents in every dollar contributed and at the 39% rate it is 24 cents. Once income plus contributions passes $250,000 the fund's rate doubles to 30% under Division 293 and the saving roughly halves.

Yes, and silently. Each year's unused amount lasts five years and is then gone for good. The 2021-22 amount is the oldest one still usable and it expires on 30 June 2027. Nothing warns you, nothing rolls it over, and the ATO does not write to tell you it has happened — the figure in myGov simply reads lower the following July.

No, and this is the part no tax figure can show you. Superannuation is preserved: for everybody now, preservation age is 60, and before then it cannot be reached at all without meeting a condition of release. From 65 it is available whether you have retired or not. The report states your own position on the page rather than in a footnote, because for a lot of people it decides the question on its own.

No. This is an information service: it applies the published rules to the figures you enter and shows what they produce, with every working visible. It ranks contribution amounts on one stated arithmetic measure — the tax kept after the fund's 15% — and does not recommend one. Whether you can afford to lock the money away, and whether your fund will accept the contribution, are not in that measure.

This one only works before 30 June.

A contribution made in July cannot be deducted against a gain made in June, and the oldest slice of your unused cap is gone by then anyway. The return is lodged months later, when there is nothing left to decide. Three minutes now is the cheapest three minutes in the whole transaction.

No card. No sign up. Your answer on the next screen.

Your unused cap is a real number, the ATO already holds it, and it is worth more this year than it will be next year.

Seven short questions. At the end you will know your contribution room, whether you pass the balance test, and what it is worth.

Step 1 Just started

    Figures as at .

    1 What is putting extra income into this year?

    Unused super contribution cap is worth most in a year your income jumps. This first question decides whether half the amount is taxed or all of it.

    Which of these is it?

    Short steps, and only the questions that decide most of the answer.

    2 Your super, and your age

    One date and one number decide whether the carried forward amount is available to you at all: your total super balance at the last 30 June, against $500,000.

    $

    All your super accounts added together, including any pension accounts. It is in the superannuation section of myGov and on your annual statement.

    It decides the work test from 67, the cut-off at 75, and when you could get the money back out.

    From 67 to 74 this is what decides whether a deduction is allowed at all. Employed or self-employed both count; volunteering and managing your own investments do not.

    From 75 a fund can only accept a personal contribution received on or before the 28th day of the month after your birthday. After that the door is closed whatever cap you have left.

    Without it, and above the thresholds, the Medicare levy surcharge applies on top of the ordinary levy.

    It doubles the Medicare levy surcharge thresholds. Their income is not asked for and is not used.

    The test is run again at every 30 June, and the contribution you make this year counts towards next year's balance.

    3 What has already gone into super

    The concessional cap is not extra room on top of what your employer puts in. Employer contributions, salary sacrifice and anything you claim a deduction for all come out of the same $32,500 a year.

    In myGov it is under the ATO service, then Super, then Information, then Carry forward concessional contributions.

    $

    The total the ATO shows as available to you. Do not include this year's own cap — that is added from the next step.

    What went in during each of the five years still inside the window. Each year's unused amount has its own expiry date, and the oldest one goes first.

    $

    Expires 30 June 2027. This is the one with a deadline on it.

    $

    Superannuation guarantee was 10.5% of ordinary earnings that year.

    $

    Superannuation guarantee was 11%.

    $

    The cap rose that year and superannuation guarantee was 11.5%.

    $

    The year that has just finished. This is the one myGov is most likely to still be updating.

    Going over the cap is not a disaster, and it is not free either. The report never proposes an amount above your room.

    4 Your income this year, before the one-off

    A deduction is worth whatever rate the income it removes was taxed at. This is the floor the one-off lands on top of, and it decides how much of it falls in the top band.

    $

    Before tax. Everything you expect to be taxed on this year except the one-off amount on the next step.

    $

    Rent, interest, dividends, trust distributions, a taxable pension. Net of the deductions you would normally claim against them.

    $

    The compulsory 12% of ordinary earnings, for the whole financial year. It uses up this year's cap before anything you contribute yourself.

    $

    Extra contributions arranged through your employer out of pre-tax pay. It comes out of the same cap.

    Every figure here uses the Australian resident tax rates, for the whole income year.

    A personal deductible contribution does not move you into a lower Medicare levy surcharge tier.

    It does not reduce a compulsory HELP repayment either.

    Nor Family Tax Benefit, child support, or the private health insurance rebate.

    5 The one-off amount

    For a sale, the year that counts is the year you signed the contract, not the year it settled.

    $

    Sale price less what you paid for it, less the costs of buying and improving it. Do not halve it — the discount is applied below.

    The extra amount you expect to be taxed on. All of it is assessable, so there is no discount to apply.

    Contract to contract, not settlement to settlement.

    $

    Agent commission, advertising, conveyancing, auction and legal costs of the sale. They come off before the discount.

    $

    Carried forward from earlier years, or made on something else this year. They also come off before the discount.

    For an inherited asset the twelve months usually runs from when the person who died acquired it, so the discount is nearly always available.

    If small business capital gains tax concessions apply to the sale, work out the gain after those concessions and put that figure in above.

    Selling an investment property is not a downsizer sale, and the two are not alternatives to each other.

    6 What you could actually contribute

    Contribution room is one ceiling and cash is another. A third one is your own taxable income — a personal deduction cannot take it below nil.

    $

    Usually the sale proceeds less whatever the money is already promised to. Leave it at nil and the report prices the room without a cash limit.

    $

    Used to price contributing next year instead. Leave it at nil and we assume next year looks like this year without the one-off.

    Printed on the cover and nowhere else. It is not sent to the assistant and never leaves the report.

    Money contributed to super is preserved. Preservation age is 60 for everybody now.

    From 67 to 74 a deduction needs 40 hours of paid work in 30 consecutive days.

    From 75 a fund can only accept a personal contribution in a short window around your birthday.

    An after-tax contribution is a different arrangement with a different purpose, and this calculator does not price it.

    Splitting last year's contributions to a spouse is possible and does not change whose deduction it is.

    First, the three things nobody explains

    1
    Unused cap is kept, for five years, and then it is not

    Everyone has an annual limit on the super that goes in before tax — $32,500 this year. Whatever you do not use is carried forward and can be added to a later year. Each year's leftover lasts five years and then disappears, and nothing warns you when it does.

    2
    Only if your balance was under $500,000

    The carried forward part is available only where your total super balance at the 30 June just gone was under $500,000. It is a hard line, not a sliding scale, and it is measured on that one date and no other.

    3
    What it is worth is the gap between two rates

    A deduction is worth whatever rate the income it removes was taxed at, and the fund takes 15% on the way in. What you keep is the difference. That is why the same contribution is worth 32 cents in the dollar to one person on this page and almost nothing to another.

    Everything below is those three facts in real dollars, for eleven different households. Worked out on the current schedule.

    None of these is you.

    Your own figure turns on five things none of these people share with you: your balance at the last 30 June, what actually went in during each of the five earlier years, your income before the sale, the size of the gain, and how much cash you could put in before 30 June. Change any one of them and the ranking moves.

    These are Helena's numbers, not yours Helena Roussos is invented — 54, a hospital administrator on $118,000, selling a unit for a $380,000 gross gain, with $286,000 in super at the last 30 June and five earlier years of employer contributions behind her. Change any one of those and the gaps between the amounts change, and the order they come in changes with them.

    Nothing on this page is an answer for your situation, and none of it should be relied on for a decision about you.
    What it does show is exactly what your own report looks like and how to read it: the same engine and the same 1 July 2026 caps and rates. The later sections are shown here as outlines.
    01

    Your options, side by side

    The short version

    Seven contribution amounts priced on Helena's figures, ranked on the tax kept after the fund's 15%.

    Keeps the most tax $26,596 Everything available
    Contribution room $101,780 $18,340 this year plus $83,440 carried forward
    Kept per dollar 26c on $101,780 contributed
    Between best and worst $26,596 across the amounts priced here

    The measure, and it is the only one. Every amount is ranked on the income tax and Medicare levy it saves, less the 15% the fund takes on the way in and any extra Division 293 tax it attracts, across 2026-27 and 2027-28 together. It is arithmetic and it is not a recommendation.

    What that measure cannot see. Money contributed to superannuation is preserved: on Helena's age it is available on retirement. Whether she can do without it until then is not in any figure on this page.

    03

    The same amounts, drawn to scale

    The longer the bar, the more tax that amount keeps. Nothing on this chart says which one to choose.

    Where her unused cap actually is, year by year

    Carry-forward is not one bigger cap. It is five separate amounts, each with its own expiry date, used oldest first once this year's own cap is full.

    Tax kept, at every contribution amount from nothing to the ceiling. The marked point is the amount the report ranks first.

    Why the line is not straight. Division 293 charges an extra 15% on the lesser of Helena's concessional contributions and the $64,160 by which her income passes $250,000. Once her contributions pass that figure the extra tax stops growing, so the last $50,000 of the contribution keeps almost twice as much per dollar as the first $50,000 does.

    The dates that decide this, and the paperwork behind them

    Every date here is legislated or published. None of them is a deadline this site invented.

    DateWhat happensWhy it matters
    30 June 2027 The 2021-22 unused cap expires Unused concessional cap lasts five years. Helena's $17,700 from 2021-22 can be used in 2026-27 and in no year after it.
    30 June 2027 The last day the fund can receive a 2026-27 contribution A contribution counts in the year the fund receives it, not the year it is sent. A transfer made on 30 June that clears on 2 July is a 2027-28 contribution against a 2026-27 tax bill.
    30 June 2028 The deadline for the notice of intent A deduction is only allowed once the fund has acknowledged a valid notice of intent, and the notice has to be given by the earlier of the day the return is lodged and the end of the following income year.

    Written as the general process, not as instructions. This service is not licensed to tell any particular person what to do with their own money.

    Six more sections, and the ten charts in them

    • 07Which tax bracket the deduction comes off
    • 08The whole tax bill, with and without
    • 09The $500,000 test, this year and next

    Everything above is real arithmetic on a fictional household. Run yours and this half opens on your own figures.

    And you can ask it questions. Every report comes with an assistant that has read your report and explains any figure in it in plain English. Using it is entirely your choice, it does nothing until you press the button, and it is given the amounts on your report and never your name, your email or your account.

    That is somebody else's answer. Yours takes about three minutes and costs nothing.

    The link may have already been used. If you are still getting emails, write to us and we will stop them by hand.

    Reading is useful. Knowing what this is about to cost you is better.

    The year you sell

    A bonus or redundancy year: catch-up super contributions and the tax

    You do not need to sell anything for this to be worth doing. A large bonus, one exceptional year of self-employed income, a lump sum of back pay, or the taxable part of a redundancy payout all push income into a band you are not normally in — and a catch-up contribution comes off the top of it.

    Why a big income year works the same way as a sale

    The mechanism does not care where the income came from. Australia taxes on a progressive scale, so the last dollars of a large year are taxed at a much higher rate than the first ones. A deduction removes income from the very top of that stack.

    The difference from a capital gain is that ordinary income has no discount. A $150,000 gain on a property held over twelve months adds $75,000 to taxable income; a $150,000 bonus adds $150,000. So a given amount of one-off income does more damage than the same amount of capital gain — and a deduction against it is correspondingly more useful.

    What counts as the one-off, and what does not

    This is where a redundancy year needs care, because a termination payout is not one thing. It is usually four or five things with four or five different tax treatments, and only some of them belong in this calculation.

    Part of the payoutHow it is taxedInclude as one-off income?
    Tax-free part of a genuine redundancyNot assessable at allNo
    Employment termination payment (the taxable balance)Its own concessional rates up to a capNo
    Unused annual leave paid outOrdinary rates, with an offset in some casesGenerally yes
    Unused long service leave paid outDepends on when it accruedAsk a tax agent
    Salary and wages up to the last dayOrdinary ratesYes, in the salary field
    A bonus or ex gratia amount that is ordinary incomeOrdinary ratesYes

    Putting a whole termination payout into a calculator as ordinary income overstates the answer, often by a lot. The figure that belongs here is the part that goes in at ordinary marginal rates and nothing else.

    A worked example

    Bianca is 41 and works as a contract project manager. Four ordinary years on around $118,000 were followed by one where a long project finished and she invoiced an extra $145,000. Her taxable income for the year is $263,000 rather than $118,000.

    She has $205,000 in super, so she passes the $500,000 test comfortably. Her employer contributions have never filled the cap, leaving $87,340 of unused cap, and $18,340 of this year's own cap. Room: $105,680 — but she has $90,000 of cash available, so the cash is what binds rather than the rules.

    Contributing $90,000 removes income taxed at 47% down to $190,000, then at 39% below that. Against the fund's 15% and the Division 293 tax that a $263,000 year attracts, she keeps a little under $27,000 — and $74,550 of the contribution lands in her super.

    The following year her income goes back to $118,000, where the same contribution would have been worth about a third less. That is the whole argument for using the room in the year the income is unusual.

    The Division 293 problem in a redundancy year

    Division 293 charges an extra 15% on concessional contributions where income plus contributions passes $250,000, so the fund effectively takes 30%. The threshold has not moved since 2017 and is not indexed.

    A one-off income year is exactly what pushes somebody over it who is nowhere near it ordinarily, and it applies for that year alone. It does not make the contribution pointless — 47% against 30% still keeps 17 cents in the dollar — but it does roughly halve the answer, and it is the single biggest reason a rule of thumb overstates the saving. How it is actually calculated is here, and it is not what most people assume.

    Cash flow, and why a redundancy year is different

    In a sale year the money arrives and the tax bill arrives together. In a redundancy year the money arrives and the income may not restart.

    A catch-up contribution moves cash into an environment it cannot be taken back out of. Preservation age is 60 for everybody now, so somebody made redundant at 48 with an uncertain employment outlook is contemplating locking money away for twelve years at exactly the moment liquidity matters most.

    That is not an argument against it. It is an argument for the figure the calculator asks for: how much cash could you actually put in, as opposed to how much room the rules allow. The two are usually very different, and the smaller one is the one that decides.

    What a contribution does not fix

    A deduction reduces income tax and the Medicare levy. It does not reduce:

    • The Medicare levy surcharge tier, because income for surcharge purposes adds reportable superannuation contributions back on.
    • A compulsory HELP repayment, for the same reason. Somebody with a large one-off year and a HELP debt faces a repayment calculated on income the deduction did not reduce.
    • Family Tax Benefit or child support assessments.
    • Any Centrelink waiting period attached to a termination payment.

    The paperwork is the ordinary paperwork

    Nothing about a bonus or a redundancy changes the mechanics of the contribution itself. The money has to reach the fund before 30 June of the same income year, a notice of intent has to be lodged with the fund and acknowledged in writing, and the deduction is claimed in that year's return.

    One thing worth watching in a redundancy year: if you are consolidating or rolling over super accounts at the same time — which people often do when they leave a job — the notice of intent has to be given before the money leaves the account. Rolling over first destroys the deduction.

    What is your big year actually worth?

    Enter the extra income, your ordinary salary and your balance at 30 June, and we price every contribution amount against it.

    Send us a message

    You have sold a rental, a business or something you inherited, or you have had one year of income that is nothing like the others. There is a tax bill coming that is larger than any you have had before, the money to pay it is sitting in your account, and somebody has mentioned that you could have put some of it into super. The window to do anything about it closes on 30 June, which is usually months before the return is even prepared.

    None of the rules are secret. Carry-forward is section 291-20 of the Income Tax Assessment Act 1997, the $500,000 balance test is subsection (3) of it, the contribution caps are published by the ATO each year, and the individual income tax rates are in the Income Tax Rates Act 1986. The reason so few people ever see their own figures is that those rules sit across four documents, none of which is written for the person affected, and the one screen that shows the number — myGov — shows it without any arithmetic beside it.

    Catch-Up Super does one thing: it applies those published rules to your figures and shows you, in full, what they produce. Every contribution amount priced, every one ranked on one stated measure, and every working visible — down to which tax bracket each slice of the deduction comes off — so you can check it, argue with it, or take it to somebody who can.

    We do not tell you how much to contribute. We are not licensed to, and frankly the arithmetic is the part people are missing — not the opinion. Here is what licensed advice on this actually costs, if you decide you want it as well.

    1. About this policy

    This policy explains how XTO Pty. Ltd. (we, us, our) collects, holds, uses and discloses personal information, and how you can access, correct or complain about it. We handle personal information in accordance with the Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs).

    It applies to calculatedchoices.com.au and to every email we send you. It does not apply to any third party site we link to.

    2. What we never collect

    We do not ask for, and you should never send us, your Medicare number, tax file number, tax file number, super member number or myGov login, bank account details or card number. The calculator does not need them. If you send one to us anyway we will delete it rather than store it.

    We do not collect sensitive information as defined in the Privacy Act — health information, racial or ethnic origin, political or religious beliefs, sexual orientation, or criminal record. Where the calculator asks about care needs it asks about funding categories, never about a medical condition.

    3. What we collect, and why

    Information you give us

    • Account details — first and last name, email address, and optionally phone, suburb, state, postcode and your relationship to the person entering care. Used to create and secure your account and to deliver what you bought.
    • Saved reports — the figures you entered and the results produced, stored against your account only if you choose to save one. Used so you can return to and compare them.
    • Purchases — the order, amount, currency, access period and the PayPal transaction reference. Used to grant access, issue receipts and meet our tax and record keeping obligations.
    • Correspondence — what you write to us and our reply. Used to answer you and to resolve disputes.
    • Email estimates and reviews — the email address you give us to receive a free estimate, and any review you submit for publication.

    Information collected automatically

    • Technical data — IP address, browser user agent, device type, screen and viewport size, and the referring page.
    • Activity data — the pages you open, the order you open them in, time spent on each, how far you scroll, which calculator steps you complete, and which buttons you press. Used to understand where the site is confusing and to improve it.
    • Advertising identifiers — where you arrive from an advertisement, the click identifier appended to the link (for example Google's gclid) and any campaign parameters, so we can measure which advertising works.

    4. Where the calculation happens

    In your browser, on your device. The figures you type into the calculator are processed locally to produce your result. They are transmitted to us only if you choose to save a scenario to your account. If you never save one, we never receive them.

    Two exceptions, and both are things you have to choose to do:

    • If you ask us to email your free estimate, the headline figure that estimate produced is stored with your email address so the estimate we send you is the one you saw.
    • If you use the optional report assistant, the figures in the report you have open are sent to us and on to the service that answers it. That is the only part of this site that sends anything to a third party, and section 5 sets out exactly what does and does not travel.

    5. The report assistant

    A paid report comes with an optional assistant you can ask questions about your own figures. It is the one part of this site that sends anything to a third party, so it is set out here in full.

    It is entirely your choice, and it does nothing until you use it. Nothing is sent anywhere unless you open the assistant and ask a question. If you never open it, this section does not apply to you at all, and the rest of the report works exactly the same.

    What is sent when you do ask

    • A plain-text summary of the figures in the report you have open — the amounts, categories and comparisons the report already shows you on screen.
    • The question you typed, and the questions and answers already in that conversation, so a follow-up makes sense.

    What is not sent

    • Your name. The name field on the calculator is optional and is used only on your own report cover. It is not part of what the assistant is given.
    • Your email address, your account, your phone number or your street address. The assistant is not told who you are, and is given no way to find out.
    • Your Medicare number, tax file number, tax file number, super member number or myGov login, bank account or card details — we never hold these in the first place. See section 2.

    What travels is a set of amounts and categories. On its own it does not identify anybody, and we do not send anything alongside it that would.

    Who processes it

    The request is answered by Google's Gemini API, which processes it outside Australia — see sections 10 and 11. We do not train any model on your figures and we have no arrangement permitting anyone to do so; what Google does with data sent to its API is governed by its own terms, which we do not control.

    How long it is kept

    • The summary of your figures is held in our server's memory for one hour so a conversation does not have to re-send it with every question, and is then discarded. It is never written to our database.
    • The conversation itself is stored in your own browser tab and is gone when you close that tab. We do not keep a copy.
    • We record that a question was asked, and how long it was, so we know whether the feature is used. We do not record what it said.

    Because the assistant is optional, you can have the entire paid report without any of the above ever happening. Nothing in the report is withheld from somebody who never opens it.

    6. Cookies and browser storage

    We use the following, and nothing else:

    • An authentication cookie — set only when you sign in, so you stay signed in. Strictly necessary.
    • A guest identifier — so a scenario saved before you register can be attached to your account when you do.
    • A session key (browser session storage) — identifies one visit for the activity data described above. It is a random value and is discarded when you close the tab.
    • A visitor key (browser local storage) — a random value kept for up to twelve months so we can tell a returning visitor from a new one. It contains no personal information and is not shared with anyone.
    • Preferences — your light or dark theme choice.

    You can clear or block these through your browser at any time. Clearing them will sign you out and reset your preferences; the site will otherwise work normally.

    7. Analytics and advertising

    We use Google Analytics and Google Ads to measure how people find and use the site and whether our advertising is worth running. Where these are enabled, Google receives your IP address, device and browser information, the pages you viewed, and — when you complete a purchase — the order reference and the amount paid. Google may set its own cookies and may combine this with data it holds from other sources. Google's handling of that data is governed by its own privacy policy, not ours.

    We do not sell your personal information, and we do not disclose it to data brokers, advertising networks other than as described above, super funds, accountants, financial advisers or the ATO, or anyone who might try to sell you something.

    You can opt out of Google Analytics using Google's browser add-on, and you can adjust personalised advertising in your Google account settings.

    8. Payments

    Payments are processed by PayPal. Your card or account details are entered on PayPal's systems and are never transmitted to, seen by, or stored on our servers. We receive only the transaction reference, the amount, the status and the email address associated with the payment.

    9. Who we disclose information to

    • Service providers who host the site, send our email and process payments, and only so they can perform that function.
    • Google, as described in sections 5 and 7.
    • Professional advisers — our accountants and lawyers, under obligations of confidence.
    • A purchaser of our business, if it is ever sold, on terms that require them to honour this policy.
    • Law enforcement, courts or regulators, where we are required or authorised by law.

    10. Overseas disclosure

    Some of these providers store or process data outside Australia, principally in the United States (Google, PayPal) and, depending on our email provider, in other countries. By using the site you acknowledge that we take reasonable steps to ensure overseas recipients handle your information consistently with the APPs, but that we cannot control and are not accountable for how an overseas recipient handles it once disclosed, and that you may not be able to seek redress in that jurisdiction.

    11. Security

    The site runs entirely over HTTPS. Passwords are stored as salted PBKDF2 hashes, not as text anyone here can read. Access to the database is restricted to those who need it. No system is perfectly secure, and we cannot guarantee the security of information transmitted over the internet, but we take reasonable steps to protect it from misuse, interference, loss and unauthorised access, modification or disclosure.

    If a data breach occurs that is likely to result in serious harm, we will notify you and the Office of the Australian Information Commissioner as required by the Notifiable Data Breaches scheme.

    12. How long we keep it

    • Account and saved reports — until you delete them or ask us to.
    • Order and payment records — seven years, as required by Australian tax law. We cannot delete these earlier, even on request.
    • Activity data — up to twenty‑six months, then deleted or aggregated so it no longer identifies anyone.
    • Email leads — until you unsubscribe, then only the record needed to honour that unsubscribe.

    13. Direct marketing

    If you give us your email address for a free estimate we may follow up about the full report. Every commercial email we send identifies us and carries a functional unsubscribe link, as required by the Spam Act 2003 (Cth). We action unsubscribes immediately. You will still receive transactional email — receipts, access details and password resets — because those are not marketing.

    14. Accessing, correcting and deleting your information

    Write to support@calculatedchoices.com.au. We will:

    • give you access to the personal information we hold about you, or explain why we cannot;
    • correct anything inaccurate, out of date, incomplete, irrelevant or misleading;
    • delete your account and every scenario attached to it, subject to the retention periods in section 12.

    We will respond within 30 days and will not charge you for making a request. We may need to verify your identity first.

    15. Complaints

    If you think we have breached the APPs, write to support@calculatedchoices.com.au with "Privacy complaint" in the subject line. We will acknowledge within 5 business days and respond substantively within 30 days.

    If you are not satisfied with our response, you may complain to the Office of the Australian Information Commissioner: oaic.gov.au, 1300 363 992, or GPO Box 5288, Sydney NSW 2001.

    16. Children

    The site is intended for adults deciding how much to put into super in a year their income is unusually high. It is not directed at children and we do not knowingly collect personal information from anyone under 18.

    17. Changes to this policy

    We may update this policy. The effective date at the top changes when we do. Where a change is material we will tell you by email or by notice on the site before it takes effect. Continuing to use the site after that means you accept the updated policy.

    1. Agreement

    By using calculatedchoices.com.au (the site) or buying a pass you agree to these terms. If you do not agree, do not use the site. In these terms we, us and our mean XTO Pty. Ltd.; you means the person using the site or, where you use it on behalf of another person or an entity, both you and that person or entity.

    2. Eligibility

    You must be at least 18 and legally able to enter a contract. The site is intended for use in Australia and applies Australian law and the published superannuation contribution caps and income tax rates only. If you use it from outside Australia you do so on your own initiative and are responsible for local compliance.

    3. What this service is

    Catch-Up Super is an information and calculation service. It applies the published superannuation contribution caps and income tax rates to figures you supply and reports what those rules produce, showing its workings and naming the fee schedule used.

    4. What it is not

    It is not financial product advice, personal advice, legal advice, tax advice, accounting advice or superannuation or taxation advice, and it is not a recommendation to acquire, dispose of or deal in any financial product.

    • We do not hold an Australian Financial Services Licence and are not authorised representatives of any licensee.
    • We do not know your full circumstances, objectives, financial situation or needs, and nothing produced by the site takes them into account.
    • Where the report ranks options it does so on a single arithmetic measure that deliberately ignores everything a number cannot capture — health, family circumstances, tax position, estate planning, which super fund the money goes to, and what actually matters to you.
    • We receive no commission and have no relationship with any super fund, accountant, tax agent, financial adviser or the ATO.

    You should obtain independent, licensed advice before acting. Any decision you make is yours.

    5. Accuracy and estimates

    We take considerable care to keep the rates current and the formulas right, and every report prints the schedule it was built on. Even so:

    • All output is an estimate based on the figures you entered. If those figures are wrong, incomplete or out of date, the output will be too.
    • Your actual unused concessional cap is the figure held by the ATO and shown in myGov, and a deduction is only valid once your super fund has acknowledged the notice of intent you lodge with it. Those prevail over anything the site produces.
    • Rates, thresholds and caps change by legislation and indexation, and legislation can change without notice or retrospectively.
    • Projections rely on assumptions about the future — investment returns, indexation, home values, length of stay — which are inherently uncertain and will not be accurate.

    Always confirm before you act.

    6. Your responsibility for decisions

    You acknowledge and agree that you are solely responsible for evaluating the output, for verifying it against official sources, for obtaining independent professional advice, and for every decision you make or do not make. We are not your adviser and no fiduciary or advisory relationship arises from your use of the site.

    7. Accounts

    You are responsible for keeping your password confidential and for everything done under your account. Tell us immediately at support@calculatedchoices.com.au if you suspect unauthorised use. We may suspend or close an account we reasonably believe is being used in breach of these terms.

    8. Passes, price and payment

    • A pass grants access to the full report from the moment payment is confirmed, and it does not expire. It does not renew and nothing is charged automatically. There is no subscription and no card is kept on file.
    • Prices are in Australian dollars and include GST where applicable. We may change prices at any time; the price shown when you buy is the price you pay.
    • Payment is processed by PayPal under its own terms. We do not receive your card details.
    • A pass is for personal or single household use. It is not transferable and may not be shared, resold or used to provide a service to others.

    9. Reports you export

    A report you export as a PDF or otherwise save remains yours to keep and to show to family, an adviser or a super fund. That licence is personal and non‑commercial. It does not permit republication, resale, or use as part of a product or service you provide to others.

    10. Refunds

    Our promise: if the calculator cannot properly model your circumstances, or something has gone wrong, write to us within 14 days of purchase and we will refund the pass. No form and no argument. We would rather refund you than have you rely on a number that does not fit.

    This is a voluntary commercial guarantee offered in addition to, and it does not limit, your rights under the Australian Consumer Law. Refunds are made to the original payment method within five business days of us accepting the request.

    11. Acceptable use

    You must not:

    • scrape, crawl, harvest, mirror or systematically extract the site or its content;
    • attempt to access the paid report engine, any account, or any data without authorisation;
    • reverse engineer, decompile or attempt to derive the source of any part of the service;
    • interfere with the site's operation or security, or impose an unreasonable load on it;
    • resell, sublicense or commercially exploit the service or its output;
    • use the site to provide financial, legal or placement advice to third parties; or
    • use it unlawfully, or to infringe anyone's rights.

    12. Intellectual property

    All content, code, calculation methodology, report design, text and branding on the site is owned by us or licensed to us and is protected by copyright and other laws. Legislated rates and government data are not owned by anyone; our expression, arrangement and implementation of them is. Nothing in these terms transfers ownership to you.

    13. Availability

    We aim to keep the site available but do not guarantee it will be uninterrupted, timely, secure or error free. We may modify, suspend or discontinue any part of it, and may perform maintenance, at any time. If we permanently discontinue the service while your pass is running, we will refund the unused portion.

    14. Third parties

    The site relies on third party services including PayPal, Google and our hosting and email providers, and links to third party sites and government resources. We are not responsible for those services or sites, their availability, their content or their terms.

    15. Australian Consumer Law

    Our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law. For major failures with the service, you are entitled to cancel your service contract with us and to a refund for the unused portion, or to compensation for its reduced value. You are also entitled to be compensated for any other reasonably foreseeable loss or damage. If the failure does not amount to a major failure, you are entitled to have problems with the service rectified in a reasonable time and, if this is not done, to cancel your contract and obtain a refund for the unused portion of the contract.

    Nothing in these terms excludes, restricts or modifies any consumer guarantee, right or remedy conferred by the Australian Consumer Law or any other law which cannot lawfully be excluded, restricted or modified. If any part of these terms would do so, that part does not apply.

    16. Limitation of liability

    Subject always to section 15, and to the maximum extent permitted by law:

    • the site and its output are provided "as is" and "as available", and we exclude all warranties, conditions, guarantees and representations not expressly set out in these terms, whether express, implied, statutory or otherwise, including as to accuracy, fitness for a particular purpose, merchantability and non‑infringement;
    • we are not liable for any indirect, incidental, special, punitive or consequential loss, or for any loss of profit, revenue, savings, opportunity, goodwill, data, anticipated benefit, or for any loss arising from a decision made or not made in reliance on the site, however arising and whether in contract, tort (including negligence), statute or otherwise, even if we were advised of the possibility;
    • our total aggregate liability to you for all claims connected with the site or these terms is limited, at our election, to resupplying the service or to refunding the amount you actually paid us in the twelve months before the claim arose; and
    • where liability cannot be excluded but can be limited, it is limited as set out above.

    You agree that this allocation of risk is reasonable given the price of the service and that the service is information rather than advice.

    17. Indemnity

    To the maximum extent permitted by law, you indemnify us against any claim, loss, liability, cost or expense (including reasonable legal costs) arising from your breach of these terms, your misuse of the site, or your provision of the site's output to a third party who relies on it. This does not apply to the extent the claim arises from our own breach, negligence or wilful misconduct.

    18. Termination

    You may stop using the site at any time. We may suspend or terminate your access immediately if you breach these terms. Sections 4, 5, 6, 9, 12, 15, 16, 17, 19 and 20 survive termination.

    These terms are governed by the laws of New South Wales, Australia. You and we submit to the non‑exclusive jurisdiction of the courts of New South Wales and the courts entitled to hear appeals from them.

    21. General

    • Changes. We may amend these terms. The effective date changes when we do, and material changes will be notified by email or on the site before they take effect. The terms in force when you bought a pass govern that purchase.
    • Severability. If a provision is unenforceable it is read down to the minimum extent necessary, or severed, without affecting the rest.
    • Waiver. A failure to enforce a right is not a waiver of it.
    • Assignment. You may not assign these terms without our consent. We may assign them on a sale of the business.
    • Entire agreement. These terms and the Privacy Policy are the entire agreement between us about the site.
