Downsizer Contribution Australia: $300k Super Boost When You Sell Your Home (2026-27)

Sell your home at 55 or older and the tax rules let you move up to $300,000 per person — $600,000 for a couple — into super, on top of every other contribution cap. No work test. No balance test. No tax on the way in. The price of admission is a strict 90-day deadline from settlement, a one-page ATO form your fund must hold before or when you contribute, and a one-shot-per-lifetime rule almost everyone misunderstands. Here is how it all works in 2026-27, including the Division 296 wrinkle the other guides are not mentioning.

How the downsizer contribution works

A downsizer contribution is a special class of super contribution tied to a home sale. Introduced in 2018, the age threshold dropped from 60 to 55 in January 2023, which opened it to a much bigger group of pre-retirees.

Compared with a normal after-tax contribution, it is strikingly generous:

• $300,000 per person, outside the normal caps. It does not count towards the 2026-27 concessional cap ($32,500) or non-concessional cap ($130,000), and it neither triggers nor uses up the bring-forward rule.
• No work test and no upper age limit. A fully retired 80-year-old can make one.
• No total super balance test on making the contribution — people whose balances block ordinary after-tax contributions can still use it.
• No 15% contributions tax on entry. It enters as a non-concessional contribution.
• You do not have to buy a smaller home. Despite the name, there is no requirement to downsize or even to buy another home. Sell and rent, sell and upsize, move in with family — all fine.

One ceiling to note: a couple’s combined contributions cannot exceed the total sale proceeds. Sell for $500,000 and the pair of you can contribute at most $500,000 between you.

The official eligibility rules

The ATO requires all seven of these:

Spouse stacking: $600,000 from one sale

Both spouses can each contribute up to $300,000 from the same sale — even if only one of them is on the title. The non-owning spouse just has to meet the other conditions. So if the house is entirely in your partner’s name, you can still put $300,000 of the proceeds into your own super account.

There are also provisions for harder cases: if the spouse who held the ownership interest dies, you can count their ownership period — including time the home sits in the deceased estate — towards your 10-year test, and transfers between spouses on relationship breakdown are accommodated. Messy ownership history is worth checking with your fund rather than assuming you fail.

What “one shot” actually means

One downsizer contribution per person, ever. Not one per home — one.

But it does not mean what at least one major guide claims: selling a home without contributing does not burn your turn. Sold at 58 and put nothing in? Sell a different home at 68 and you can still use the measure. The test is whether you have previously made a downsizer contribution.

The real trap runs the other way: contribute less than $300,000 from a sale and you cannot top it up later from another sale. Within the original 90-day window, though, you can make several contributions — across different funds if you like — totalling up to $300,000, with a separate form for each payment.

Does the home have to be your main residence when you sell?

No. It must have qualified for the main residence CGT exemption at some point — fully or partially. A home you lived in for 12 years then rented out for 8 can still qualify, provided the sale attracts at least a partial exemption. Former family homes turned rentals are a common qualifying case people assume are excluded. If the exemption mechanics are hazy, read our guides to CGT on property and the main residence exemption before you list.

Step by step: sell, form, contribute

1. Confirm your fund accepts downsizer contributions before settlement, so you are not scrambling later.
2. Note the settlement date. The 90-day clock runs from when you receive the proceeds — usually settlement day, not exchange. A long settlement buys you time.
3. Complete the ATO form — the Downsizer contribution into super form (NAT 75073), or your fund’s equivalent.
4. Give the form to your fund before or with the money. Skip this and the fund may code the money as an ordinary non-concessional contribution, which can breach your 2026-27 contribution caps and trigger excess-contributions tax.
5. Transfer within 90 days of receiving the proceeds — EFT, BPAY or cheque, however your fund takes voluntary contributions.
6. Verify the label. Confirm the fund recorded it as a downsizer contribution, not a personal one. Some people check ATO online services after their return is lodged, because a mislabel can generate an excess-contributions determination.

What if 90 days is not enough?

Ask the ATO for an extension of time. Extensions are available for genuine delays — drawn-out settlements, legal disputes, a build that is not finished — and advisers report the ATO being pragmatic when asked early; one practitioner secured an 18-month extension for a client simply by phoning ahead. Apply as soon as possible, ideally inside the original 90 days, and never contribute late without an approved extension. You cannot use an extension to manufacture eligibility, such as reaching age 55.

Worked example: $1.2 million sale, $600,000 into super

Margaret (63) and David (61) from Brisbane bought their family home in 2001 for $320,000, lived in it throughout, and sell in October 2026 for $1,200,000, settling 14 November 2026.

CGT: main residence for the entire ownership period means the sale is fully exempt — no CGT on the $880,000 gain. The $1.2 million is theirs in full.

The contributions: each already holds $450,000 in super. By early February 2027 (inside the 90 days) each lodges a NAT 75073 and contributes $300,000 — $600,000 combined.

• No contributions tax on entry; no dent in their 2026-27 concessional or non-concessional caps. David can still stack carry-forward concessional contributions from unused prior-year cap on top.
• New balances of $750,000 each — well under the $2.1 million transfer balance cap and far from the $3 million Division 296 threshold.
• Both are over 60, so in a retirement-phase pension the earnings are tax-free and withdrawals are tax-free. Under 60 with no condition of release met, the contribution is preserved — you cannot pull it back out. See super withdrawal tax rules for detail.

Inside vs outside super: say the $600,000 earns 6% a year — $36,000 of income. In a personal account at a 32.5% marginal rate, that costs about $11,700 in tax (keeping $24,300). Inside super’s accumulation phase at 15%, the tax is $5,400 (keeping $30,600) — roughly $6,300 a year better off, compounding annually, with a bigger gap once the money moves to a tax-free pension. Run your own numbers on our super calculator.

The 2026-27 stacking year: up to $722,500 at once

Because the downsizer sits outside the normal caps, one eligible person in 2026-27 can combine a $300,000 downsizer contribution, a $390,000 bring-forward non-concessional contribution (three years of the new $130,000 cap, balance tests permitting), and up to $32,500 of concessional contributions — $722,500 into super in a single year. A couple could theoretically move $1.445 million. That is a ceiling, not a target: the bring-forward has its own balance tests and Division 296 starts biting near $3 million. But it shows why advisers call the downsizer the crown jewel of late-stage super planning.

Division 296: the new 2026-27 wrinkle

From 1 July 2026, Division 296 adds a personal tax on earnings attributable to the slice of your total super balance above $3 million — an extra 15% on the $3m–$10m band, plus another 10% above $10m.

The interaction the other guides miss: a downsizer contribution counts towards your total super balance. Not towards the contribution caps — towards the balance. Sitting at $2.85 million, a $300,000 downsizer takes you to $3.15 million and into Division 296 on the excess. For most people this is irrelevant, but near $3 million it turns the decision into a calculation rather than a reflex: get advice first, because the contribution cannot be undone.

Common mistakes

• Missing the 90-day deadline. Diary the settlement date the day contracts go unconditional; if delay looms, phone the ATO before the window closes.
• Money without the form. No NAT 75073 with the fund at contribution time, no downsizer treatment — and possibly an excess-contributions surprise later.
• Locking out a spouse. The partner not on the title can still contribute their own $300,000. Couples regularly leave that capacity on the table.
• Trying to claim a deduction. Downsizer contributions are not deductible — they are after-tax money, untaxed on entry, and that is the deal.
• Exceeding the proceeds. Combined contributions cannot top the sale price: on a $500,000 sale, $300,000 each is not available.
• Forgetting preservation. At 55–59 with no condition of release met, the money is locked in. Do not contribute cash you might need next year.
• Ignoring the Age Pension. Your home is assets-test exempt; the proceeds and the super balance generally are not. A $600,000 contribution can shrink or remove pension entitlements, and deemed income can hit the income test. Model it before you sell.
• Thinking a prior sale burned your turn. No downsizer contribution made means no turn burned.

Tips to get it right

• Treat it as your last contribution, not your first. One-shot, any age over 55, no balance limits — so use salary sacrifice, carry-forward and bring-forward first, and keep the downsizer in reserve. Do not sell a qualifying home at 56 “to use it” if a bigger sale may come at 70.
• Time the sale around your 55th birthday. Age is tested at contribution: sell at 54, settle, turn 55, contribute inside the window — that works. Contribute at 54 — that does not.
• Split deliberately across funds inside the 90 days (one form per payment) — some couples use this to equalise balances for transfer-balance-cap planning.
• Match the 90 days to your cash flow. The money must come from the proceeds. If they are tied up paying out a mortgage or bridging into the next purchase, make sure $300,000 per person is liquid inside the window.
• Kill the FHSS myth. A downsizer contribution cannot be released later under the First Home Super Saver scheme. Anyone saying otherwise is confusing it with ordinary voluntary contributions.
• Get advice near $3 million. Division 296, the transfer balance cap and estate planning interact in ways a checklist cannot resolve.

Frequently asked questions

Do we have to buy a smaller home to qualify?

No. There is no requirement to buy a smaller, cheaper or any home. The ATO only cares that you sold an eligible home and met the conditions.

Only my spouse is on the title. Can I still contribute?

Yes, if you meet the other rules — 55+, the 10-year ownership satisfied through your spouse, main-residence exemption applying, 90-day timing, the form, and no prior downsizer contribution. Each of you can put up to $300,000 into your own accounts.

We sold for $480,000. Can we each still contribute $300,000?

No. Combined contributions cannot exceed total sale proceeds — $480,000 between you. Split it $300,000/$180,000, $240,000/$240,000, or any mix up to $300,000 each.

Settlement keeps getting delayed and 90 days will pass. What now?

Contact the ATO as soon as possible — ideally before the 90 days expire — and request an extension, explaining the circumstances. Extensions are granted for genuine delays. Never contribute late without an approved extension.

I put in $200,000 from last year’s sale. Can I add $100,000 now?

Not from a later sale, and not once your original window closed. One downsizer opportunity per person, capped at $300,000. Within the original 90 days you could have topped up to $300,000 across several payments — which is why you plan the full amount before the first dollar moves.

Can I claim a tax deduction, and will it affect my Age Pension?

No deduction is available — it is after-tax money, untaxed on entry instead. And yes, it can affect the Age Pension: the family home is assets-test exempt, but the proceeds and your super balance generally are not, and deemed income can affect the income test. Talk to Services Australia’s Financial Information Service before you sell if the pension matters to you.

The bottom line

The downsizer contribution is the most generous single contribution the super system offers: $300,000 per person, no caps, no work test, no balance test, no entry tax, both spouses from one sale. In 2026-27 it pairs with higher general caps and the new Division 296 regime — more valuable than ever, and slightly more dangerous near $3 million.

The mechanics are simple but unforgiving: eligible home, 55+, form with the fund, money in within 90 days of settlement, once per lifetime. Get those five right and a home sale becomes the biggest single boost your super ever receives. Start with the ATO’s official downsizer super contributions page and take it from there.
