Downsizer Superannuation Contribution: What Brisbane Sellers Over 55 Need to Know

The federal Downsizer Contribution scheme allows eligible Australians aged 55 and over to put up to $300,000 each from the sale of their home into superannuation. For Brisbane sellers who have held the family home for decades, it is one of the more useful financial planning tools attached to a sale, and one of the most misunderstood.

The Downsizer Contribution is a Commonwealth superannuation measure, not a real estate scheme and not a tax concession on your sale. It lets eligible Australians aged 55 and over move up to $300,000 each (so up to $600,000 per couple) from the proceeds of selling their home into superannuation, on top of and separate from the usual contribution caps. It was introduced in 2018 with an initial eligibility age of 65, dropped to 60 in 2022 and then to 55 in January 2023. The age threshold has not moved since, so the rule as of 2026 is simply that you must be 55 or over at the time you make the contribution.

For many Brisbane sellers in their late 50s, 60s and 70s who have lived in the same home in suburbs like Bulimba, Hawthorne, Norman Park, Camp Hill or Carindale for twenty or thirty years, a sale produces a large lump sum that needs a destination. The downsizer scheme is one of the few mechanisms available to get a significant amount of money into the concessionally taxed super environment in a single transaction, without bumping into the standard contribution caps that ordinarily limit what you can put in each year.

The eligibility rules, in plain terms

To make a downsizer contribution, all of the following need to be true:

Age. You must be 55 or older at the time of the contribution. There is no upper age limit. This is unusual in super: most contribution types have a work test or age cap once you are over 67, but the downsizer contribution does not. A 78-year-old can make one just as easily as a 56-year-old.

Ownership period. You (or your spouse, or you and your spouse together) must have owned the home for at least 10 years. The clock runs from the settlement of your original purchase to the settlement of the sale, not from the contract dates. If you bought in 2017 and you are settling the sale in 2026, you are over the line; if you bought in 2017 and settle in early 2027, you are not.

Australian home. The property must be in Australia. It cannot be a caravan, mobile home or houseboat. Almost any standard Brisbane house, townhouse or apartment will satisfy this.

Main residence status. The home must qualify, in full or in part, for the capital gains tax main residence exemption. A home you lived in for the whole period of ownership clearly qualifies. A home that you lived in for part of the period and rented out for part of it qualifies on a partial basis, and you can still make a downsizer contribution provided some portion of the sale is covered by the main residence exemption. A pure investment property you never lived in does not qualify.

Contribution amount. You can contribute up to $300,000 per person, capped at the total sale proceeds. So if the home sells for $1.6 million and you and your spouse are both eligible, you can together contribute up to $600,000. If a single seller has a sale of $250,000, the contribution is capped at $250,000, not $300,000.

Timing. The contribution must reach your super fund within 90 days of settlement. An extension can be requested from the ATO in genuine cases (a fund delay, an unexpected health event), but the default is 90 days and missing it without a granted extension means the contribution will be rejected as a downsizer and counted against your normal caps.

Form. You must give your super fund a completed ATO downsizer contribution form (NAT 75073) before or at the time of the contribution. A contribution made without the form will not be treated as a downsizer contribution, even if you would otherwise have qualified, and it cannot be retrospectively reclassified.

Once per home sale. The downsizer rule is a one-off in connection with the sale of one home. You cannot split it into two transactions. If you sell again later, you may be eligible to make another downsizer contribution in connection with that future sale, provided the eligibility rules are met again, but you cannot use the scheme twice on the same property sale.

It is not actually about downsizing

The name is misleading and worth unpacking, because it confuses people. The scheme has nothing to do with whether you are actually downsizing. You do not need to buy a smaller home. You do not need to buy any home at all. You can sell the family home in Norman Park, rent for a year, and still make a downsizer contribution. You can sell and buy something larger or more expensive, and still make a downsizer contribution. The only requirement on your next housing decision is that you make one of your own choosing, the scheme is silent on it.

This matters for Brisbane sellers who are weighing up moving from a four-bedroom house in the inner east to a two-bedroom apartment in New Farm, or moving in with adult children, or moving into a retirement village, or moving regionally to the coast. All of those paths are compatible with making a downsizer contribution. The decision about where to live next can be made on its own merits, not on whether it preserves super eligibility.

Why the contribution caps matter

The reason the downsizer contribution is valuable is that it sits outside the ordinary contribution caps. In the 2026 financial year, the standard non-concessional contribution cap is $120,000 per person per year, with a three-year bring-forward of up to $360,000 available to people under 75 who satisfy the total super balance conditions. The concessional (pre-tax) cap is $30,000 per person per year. For most people in their 60s and 70s, particularly those with super balances already near the transfer balance cap, the bring-forward rule is restricted or unavailable.

A downsizer contribution is treated as non-concessional but does not count against the non-concessional cap. It is not blocked by a high total super balance (although your subsequent ability to make other non-concessional contributions may be). It does not require a work test. For someone aged 72 who is retired, has a super balance over $1.5 million and has sold the family home, the downsizer contribution may be the only practical route to get another $300,000 into super at all. Without it, the cap rules would block almost any other path.

How a Brisbane couple should think about the numbers

Imagine a couple in Camp Hill, both aged 65, who bought their home in 1998 for $185,000 and are selling in 2026 for $1.7 million. The home has been their principal residence for the entire period of ownership, so the sale is fully CGT-exempt under the main residence exemption. After agent fees, marketing, conveyancing and the mortgage payout on a small remaining loan, they expect to net around $1.55 million.

They have already decided to move to a smaller home on the bayside, with a purchase price of around $950,000. That leaves them with roughly $600,000 of surplus cash from the sale (less transfer duty and moving costs on the new purchase). They are both eligible for a downsizer contribution. They each elect to contribute the maximum $300,000 into their respective super accounts within 90 days of settlement. That moves $600,000 into a concessionally taxed environment with earnings taxed at 15% in accumulation phase, or 0% once moved to pension phase up to the transfer balance cap, instead of leaving it in a personal account where investment earnings are taxed at their marginal rates.

The numbers will differ for every household, but the structure of the planning is the same: work out what the sale will net, what the next housing decision costs, what surplus cash is produced, and whether moving some or all of that surplus into super through the downsizer mechanism produces a better long-term outcome than leaving it outside.

The interaction with the Age Pension and Centrelink

The downsizer contribution interaction with the Age Pension is the part most sellers overlook, and the one that can change whether the strategy is sensible for a particular household. The family home is exempt from the Age Pension assets test. Money inside super in accumulation phase is also exempt for people under Age Pension age but is fully assessable once you reach Age Pension age, regardless of whether you have claimed the pension or not. Money inside an account-based pension is assessable. Money sitting in your bank account is assessable.

The practical implication: a couple just below the Age Pension assets test threshold who sell the family home and put $600,000 from the proceeds into super through the downsizer contribution will see their assessable assets rise by $600,000 if they are at or over Age Pension age. Depending on where they sit on the taper, that can reduce or eliminate Age Pension entitlement they would otherwise have received. The same applies whether the money goes into super or stays in the bank, the family home is the only one of those that was exempt.

This does not mean the downsizer contribution is a bad idea. For a couple who are well above the assets test threshold anyway, or who are below pension age, or who are not relying on the pension, the assets test impact is irrelevant. For a couple sitting on the edge of pension eligibility, it is worth modelling carefully before committing. A financial adviser or a Centrelink Financial Information Service officer can run the numbers for your specific household.

Both spouses can contribute, even if only one is on the title

One of the more useful and less well-known features of the scheme is that both members of a couple can each make a downsizer contribution, even if only one of them is on the title of the home being sold. The eligibility for each spouse is assessed individually, but the ownership and main residence tests can be satisfied through either spouse. So if the home is in one partner's name but it has been their joint home for 25 years, both partners can each contribute up to $300,000 (collectively up to the total sale proceeds).

This is particularly relevant for older couples where one spouse was the original purchaser or where the title was never updated through marriage or a relationship change. It is worth checking your specific arrangement with a financial adviser or accountant before settlement, because the eligibility paperwork needs to reflect the actual ownership and main residence history correctly.

What to do in the lead-up to settlement

If you are planning to make a downsizer contribution from your Brisbane sale, the work in the run-up to settlement is mostly administrative and mostly happens away from the real estate side of the transaction. Three things matter most.

Confirm eligibility with your super fund. Speak to your fund (or each fund, if both spouses are contributing into separate funds) and confirm they accept downsizer contributions. Most do, but some self-managed super funds and some smaller industry funds have administrative quirks worth knowing about. Get the relevant form (ATO NAT 75073) and confirm the fund's preferred process and timing.

Plan the cashflow around the 90 day window. The contribution has to be in the fund within 90 days of settlement. If the sale settles on 1 August, the contribution needs to be received by the fund by 30 October. Build that into your settlement-to-contribution timeline rather than leaving it as something to think about after the keys have changed hands.

Get advice on the larger plan. The downsizer contribution is rarely the only financial decision triggered by a home sale. It interacts with the rest of your super position, your Age Pension entitlement, your investment plan for the next 20 years and any estate planning intentions you have. The contribution itself is straightforward, the surrounding decisions deserve a conversation with a licensed financial adviser before settlement, not after.

Common errors and traps

A few things go wrong often enough to be worth flagging in advance.

The contribution is made without the ATO form. The fund treats it as a normal non-concessional contribution. If the contributor is over the cap or has a high total super balance, the contribution can then be excess, with the associated tax and administrative consequences. This is reversible only in narrow circumstances, so getting the form in front of the fund first is critical.

The 90 day window is missed because settlement was later than expected or the fund's processing time was longer than expected. Where the delay is genuinely outside your control, the ATO can grant an extension, but the request must be made and granted, it is not automatic.

The 10 year ownership test is missed by a small margin. This catches people who bought after a brief sale-and-repurchase, or whose ownership was held through a trust or a company at some point. Where the legal ownership has changed during the 10 year period, the test needs careful examination. Your solicitor or conveyancer can help confirm the relevant ownership period from the title history.

One spouse assumes they are not eligible because they are not on the title. As covered above, this is wrong. Both spouses can be eligible based on the same property, provided each individually meets the age and main residence conditions.

The seller assumes the contribution will be tax deductible. It is not. The downsizer contribution is a non-concessional contribution and does not produce a personal tax deduction. The benefit is in the long-term concessional taxation of earnings inside super, not in a deduction in the year of contribution.

Where the downsizer contribution sits in the larger picture

For most Brisbane sellers over 55 who have owned the family home for a long time, the home sale is the single largest financial event of their adult life. The downsizer contribution is one of the few mechanisms specifically designed for that event. It is not the only tool, and for households where the pension interaction is significant or where the surplus cash needs to be readily accessible for the next housing move, leaving the money outside super or staging it differently may be the right answer. But it is a tool worth understanding properly before settlement, because the 90 day window means decisions made after the keys change hands often cannot be undone.

The article above describes the scheme as it stands in 2026. The eligibility rules are set by federal legislation and the figures (the $300,000 cap, the 10 year ownership test, the 55 age threshold, the 90 day contribution window) can change. Before relying on any of this for a specific decision, confirm the current rules with your accountant, your financial adviser, or the ATO directly.
