In short

The downsizer contribution lets eligible Australians aged 55+ contribute up to $300,000 each ($600,000 per couple) from the sale of their home into super, outside normal contribution caps. It's a one-time-per-person opportunity with a strict 90-day window. For Age Pension-age homeowners, though, it usually doesn't reduce Centrelink assessable assets — it just shifts them from an exempt home into assessable super.

Selling the family home is one of the largest financial events in a retiree's life. For eligible Australians, it also opens a brief window to move up to $300,000 each into superannuation — outside the usual contribution caps — using the sale proceeds. This is called the downsizer contribution, and while it offers genuine advantages, those advantages are frequently misunderstood. For some retirees, the benefit is more modest than it first appears.

The rule allows an eligible person to contribute up to $300,000 from the proceeds of selling their principal residence into superannuation. For a couple where both members are eligible, the combined maximum is $600,000. The amount contributed cannot exceed the actual sale proceeds — so a couple selling for $400,000 can contribute at most $400,000 between them, not $600,000. Confirmed eligibility (FY2025-26) per ATO (https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/super/growing-and-keeping-track-of-your-super/how-to-save-more-in-your-super/downsizer-contributions-into-superannuation):

  • Age 55 or older at the time of contribution (reduced from 60 to 55 effective 1 January 2023)
  • Property held for at least 10 years before the sale
  • Property must qualify (in part or whole) for the CGT main residence exemption
  • Contribution made within 90 days of settlement (extensions permitted at ATO discretion)
  • Contribution capped at $300,000 per person, $600,000 per eligible couple (combined)
  • Total Super Balance does NOT restrict eligibility — even members with TSB above $2.0M can use downsizer
  • Each member can use the downsizer contribution only once in a lifetime
  • The contribution is not a non-concessional contribution and does not count against any contribution cap

To make a downsizer contribution, you must have reached the age of 55 at the time the contribution is made (the eligibility age was 55 from 1 January 2023, reduced progressively from 65 since the scheme began). You must also have owned the home for at least ten years before the sale — counting years of ownership by your spouse or a former spouse toward that period is permitted. The home must have qualified for the full or partial capital gains tax main residence exemption. And the contribution must be made within 90 days of receiving the sale proceeds, with the required Downsizer Contribution Form provided to your super fund before or at the time the money is deposited.

Two things about eligibility that many retirees get wrong. First, you do not have to buy a smaller replacement home. You can sell the family home and rent, move in with family, or buy any other property — the rule is about the source of the money, not what you do with it afterwards. Second, a spouse who is not on the title can still make a downsizer contribution, provided they independently meet the age and ownership conditions. This is one of the most consistently overlooked aspects of the rule and represents genuine planning value for couples where the home is held in one name only.

The 90-day window deserves particular attention because it catches people out more often than any other part of the rule. Settlement, fund acceptance, and form lodgement all take time, and the clock starts running from the day sale proceeds are received — not from settlement. The Australian Taxation Office can extend this window on application, but approval is not guaranteed. Treating 90 days as the firm deadline, and building the contribution timeline before you list the property, is the only reliable approach.

From a tax perspective, a downsizer contribution is treated as a non-concessional (after-tax) contribution. There is no personal income tax deduction, but equally no 15% contributions tax is taken out by the fund on the way in. The contribution sits outside the standard non-concessional cap and is not affected by work test requirements. Once in the fund, it is treated like any other super balance: it can be invested, and — subject to the transfer balance cap — it can be converted to a tax-free retirement phase pension.

The transfer balance cap (TBC) limits how much superannuation each person can hold in the tax-free retirement phase. The current general TBC for FY2025-26 is $2.0 million per person (up from $1.9M in FY24-25 following CPI indexation). Personal caps may differ — check via myGov ATO portal. (See related transfer-balance-cap article for full mechanics.) For couples with combined super well below the cap, a $600,000 downsizer contribution presents no issue: the whole amount can potentially be converted to pension phase. For couples already close to the cap, the arithmetic must be done beforehand — amounts above the cap that cannot move to pension phase remain in accumulation, where fund earnings are taxed at 15%.

The most common misunderstanding about the downsizer contribution concerns its effect on the Age Pension. The contribution is sometimes presented as a way to reduce assessable assets under the Centrelink means test. For retirees who have both reached Age Pension age, this is generally not what happens. At Age Pension age, superannuation is fully included in both the assets test and the income test (via deeming — see DSS Social Security Guide section 4.4.1.10). Moving money from a bank account into super does not change your total assessable position; it shifts assets from one assessed category to another. The main purpose of the downsizer contribution is tax efficiency, not Centrelink efficiency, for this cohort.

There are three situations where the downsizer contribution does provide a meaningful advantage. The first is when at least one member of a couple is under Age Pension age: that person's super balance is not currently assessed by Centrelink, which means contributing in their name provides temporary asset-test shelter until they reach pension age. The second is when the contributed balance can be converted to retirement phase — where fund earnings are tax-free — and the contributor has headroom within the transfer balance cap to do so. The third is estate planning: superannuation with valid beneficiary nominations can be a useful tool in blended-family situations or where specific beneficiary control matters.

The downsizer contribution is a one-time opportunity per person. Once used, it cannot be used again. This makes the decision consequential: it is worth understanding the mechanics thoroughly before the window opens, not after the property has already settled.

What does an Age Pension trap from a successful downsizer look like?

Margaret and David, both 70, sell a $1.6M family home and downsize to a $900,000 unit. Surplus = $700,000. They each contribute $300,000 via downsizer ($600,000 combined) to super, leaving $100,000 in cash.

Pre-sale Centrelink position: home exempt; modest other assets; full Age Pension. Post-sale: their new $900,000 home is exempt; the $600,000 in super (now their pension/accumulation) is assessable as a financial asset and deemed for income; the $100,000 cash is also deemed.

Their assessable assets jumped from ~$60,000 (cash + small holdings) pre-sale to ~$700,000 post-sale. They are now well above the couple homeowner full-pension threshold ($481,500), in the taper zone. Pension reduction: ($700,000 - $481,500) × $3 ÷ $1,000 / 2 = ~$328/fortnight per partner. Combined Age Pension drops by ~$655/fortnight = ~$17,030/year. This is the most-overlooked downsizer trade-off: the home moves from exempt-under-Centrelink to super-which-is-assessable, often costing real Age Pension dollars even though the family's underlying wealth is unchanged.

What does a pre-Pension-age sale where super is sheltered look like?

Helen, 64, single, sells a $1.4M home. She is below Age Pension age (will be eligible at 67). She contributes $300,000 via downsizer to her own super in accumulation phase, plus uses non-concessional bring-forward to add another $360,000 (her TSB is well under $1.76M). Total super move: $660,000 from sale proceeds. The remainder she keeps as cash for living needs and a smaller home purchase.

When Helen turns 67 and applies for Age Pension, her super is now in pension phase (or remains in accumulation depending on her structure choices). The $660k counts in the assets test. But during the 3 bridging years between the sale and Age Pension age, she had no Centrelink consequences from the structure — and the funds grew tax-effectively inside super (15% earnings tax in accumulation, vs personal marginal rate outside).

The two examples illustrate the timing point: downsizer is structurally most useful when the contributor is below Age Pension age (super shelters until eligibility) — for Age Pension–age homeowners using downsizer, the assets-test impact often outweighs the contribution benefit.

Key takeaways

  • Eligible Australians aged 55 or older can contribute up to $300,000 each ($600,000 per couple) from the sale of their home into super, outside the normal contribution caps and regardless of Total Super Balance — but only once per person, ever.
  • The 90-day contribution window starts from the day sale proceeds are received, not from settlement — this is the single most common way retirees accidentally miss out on the downsizer opportunity.
  • A spouse who is not on the property title can still make their own downsizer contribution, provided they independently meet the age and 10-year ownership conditions — a frequently overlooked planning opportunity for couples.
  • For retirees who have already reached Age Pension age, a downsizer contribution usually does not reduce Centrelink assessable assets — it just moves money from an exempt home into assessable, deemed superannuation, which can meaningfully reduce Age Pension entitlement.
  • The contribution is structurally most valuable when at least one partner is still under Age Pension age, since their super remains unassessed by Centrelink until they reach pension age — sheltering the funds during the bridging years.

Frequently asked questions

Who is eligible to make a downsizer contribution?

You must be 55 or older at the time of the contribution, have owned the property for at least 10 years, and the property must qualify in whole or part for the CGT main residence exemption. The contribution must be made within 90 days of receiving the sale proceeds. There's no requirement to actually buy a smaller home — you can rent, move in with family, or buy any other property afterwards. Total Super Balance doesn't restrict eligibility, even if it's above $2.0 million.

Does a downsizer contribution reduce my Age Pension assessable assets?

Generally no, if you've already reached Age Pension age. Superannuation is fully assessable under both the Centrelink assets test and income test (via deeming) once you're at pension age, so moving money from a bank account or home sale proceeds into super simply shifts it from one assessed category to another — it doesn't reduce your total assessable position. The main benefit for pension-age retirees is tax efficiency within super, not a reduced Age Pension assessment.

How long do I have to make a downsizer contribution after selling my home?

You have 90 days from the date you receive the sale proceeds — not from the settlement date — to make the contribution, with the required Downsizer Contribution Form lodged with your super fund at or before the time of deposit. The ATO can grant an extension on application, but approval isn't guaranteed, so it's best treated as a firm deadline and planned for before the property is even listed.

Can I use the downsizer contribution more than once?

No. The downsizer contribution is a once-in-a-lifetime opportunity per person. Once you've used it — even for a smaller amount than the $300,000 maximum — you cannot use it again for a future home sale, so it's worth thinking through the full contribution amount and timing carefully before making the contribution.
