The Downsizer Super Contribution: How Selling the Family Home Can Add Up to $300,000 to Your Super in 2026-27
From age 55, selling a home you've owned for ten years or more lets you put up to $300,000 of the proceeds into superannuation as a downsizer contribution – $600,000 for a couple – without touching the usual concessional or non-concessional caps. There's no upper age limit and no work test, which is unusual for a super contribution made later in life.
In practice, the clients who come to us about this are rarely confused about the big number. What catches people out is everything around it: whether the ten-year ownership test is actually met when a property was inherited partway through, what happens if only part of the home was ever the main residence, and the 90-day window that starts ticking the moment settlement happens – not when someone gets around to calling their super fund.
Baron Tax & Accounting works with clients across Australia who are planning a home sale around retirement, and this guide walks through who actually qualifies, how the cap works for couples, what the contribution does and doesn't do to your tax and pension position, and the timing mistakes that cost people the opportunity entirely.

What a Downsizer Contribution Actually Lets You Do
A downsizer contribution lets someone aged 55 or over take part of the proceeds from selling a home they've owned long-term and put it straight into superannuation, separate from the contribution rules that apply to everything else going into that account. The cap is $300,000 per person, so a couple can between them move up to $600,000 out of a home sale and into the concessional tax environment of super.
The name is a bit misleading. Despite what it's called, the ATO doesn't require you to actually downsize – there's no rule that says the next home has to be smaller or cheaper, and you don't have to buy another home at all. We've had clients move into a retirement village, into a child's spare room, or simply decide to rent, and all of them still qualified.
What makes this different from most super contributions is the complete absence of a work test. Normally, once someone's past a certain age, continuing to add non-concessional amounts to super depends on meeting a work test or a limited exception. Downsizer contributions sidestep that entirely, which is largely the point of the measure – it was designed to free up larger homes and give older Australians one more way into super on the back of an asset most of them already hold.
Who Qualifies: Age, Ownership and the Main Residence Test
Three conditions do most of the work here, and all three need to be satisfied, not just one or two.
Age: you need to be 55 or older at the time you actually make the contribution – not when the home sold, not when the contract was signed. There's no upper age limit, which is one of the few places in the super contribution rules where that's true.
Ownership period: you, or your spouse, need to have owned the home for ten years or more before the sale, generally measured from settlement to settlement rather than from the date the contract was signed. A property inherited partway through, or a share bought into later, can still work, but the ownership period is calculated carefully rather than assumed, so it's worth checking rather than guessing.
The main residence test: the sale needs to qualify, fully or partly, for the main residence CGT exemption. This is where we see the most genuine confusion. A full exemption isn't required – a partial one is enough – but it does mean a property that was entirely a rental, or a commercial premises that was never lived in, won't qualify. Where part of a home was rented out, used for a home-based business, or only became the main residence partway through ownership, the eligibility still generally stands; it's the calculation of how much can be contributed that gets more involved.
One more condition worth flagging: you can't have made a downsizer contribution before, whether from this home or an earlier one, and you can't come back for a second round from a later part-sale of the same property.
How the $300,000 Cap Works for Individuals and Couples
The cap applies per person, not per property and not per sale. That distinction matters more than it sounds. Because the cap is personal, a couple can contribute up to $300,000 each – $600,000 combined – from a single home sale, even if only one of them is named on the title, provided both of them otherwise meet the age and ownership conditions.
Take a Brisbane couple, both 67, selling a home they've owned for 22 years for $950,000. Between them they can direct up to $600,000 of that sale into their two super accounts as downsizer contributions, leaving $350,000 free for whatever else they're planning – paying down debt, investing outside super, or simply keeping it liquid.
Two limits cap the amount in practice: nobody can contribute more than $300,000 individually, and the combined downsizer contributions from a sale can't exceed the total sale proceeds. A smaller sale caps the contribution accordingly – someone selling a $400,000 home doesn't get to still find $300,000 from somewhere else to make up the difference.
The contribution doesn't have to go in as one lump sum. It can be made in instalments within the 90-day window, with a separate form lodged for each payment – something worth knowing if the sale proceeds arrive in stages or if there's a reason to spread the timing.
Why This Contribution Skips the Usual Caps – and Where It Still Counts
A downsizer contribution doesn't count toward the concessional contributions cap or the non-concessional contributions cap for the year it's made. That's the main appeal: someone who has already used up this year's caps through salary sacrifice or other contributions can still make a downsizer contribution on top, without breaching anything.
That said, it isn't invisible to every other test in the system. It's included in your total super balance, calculated as at 30 June each year, which in turn affects whether you're eligible to make future non-concessional contributions and whether higher-balance measures, including Division 293 tax for high earners or the newer tax on very large super balances, end up applying to you. It also counts toward the transfer balance cap once the money is moved into a retirement phase pension account, the same as any other super money would.
There's a pension angle too. Money that sits in a family home is generally not assessed under Centrelink's asset test while it remains the principal home, but moving it into superannuation changes how it's assessed, especially once it sits in an account-based pension. For clients close to or already receiving the age pension, this is usually the part of the decision that deserves more attention than the contribution mechanics themselves, and it's worth checking your position with Services Australia or a financial adviser before the sale goes unconditional, not after the money has already landed in super.
The 90-Day Window You Cannot Afford to Miss
Of everything involved in a downsizer contribution, the deadline is the one piece that genuinely can't be fixed after the fact in most cases. The contribution has to be made within 90 days of receiving the sale proceeds, usually settlement, and the relevant form, the ATO's Downsizer contribution into super form, needs to be with the super fund before or at the same time as the money arrives, not sent through afterwards as a formality.
Extensions exist, but the ATO grants them only in limited circumstances, and specifically not to fix the age requirement, so turning 55 two weeks after settlement doesn't get backdated. Once a fund has the contribution and the form, it has ten business days to report it to the ATO, where it shows up in ATO online services under primary residence disposal proceeds. It's worth checking that it actually appears there and under the right category, rather than assuming the paperwork went through cleanly.
If we had to rank the risks in this whole process, this is the one that matters most. Getting the ownership period calculation slightly wrong, or choosing which spouse contributes more, are things that can usually be corrected or adjusted. Missing the 90 days generally closes the door on that sale entirely.
Mistakes We See With Downsizer Contributions
A few patterns come up often enough to be worth naming directly.
Confirming eligibility with the super fund only after the sale has already settled, rather than before signing. Not every fund, particularly some older or closed products, accepts downsizer contributions without extra steps, and finding that out with the 90-day clock already running is the wrong time.
Assuming the contribution reduces assessable income. It doesn't. The money goes in from after-tax proceeds, and there's no deduction attached to it, which is part of what makes it different from a concessional contribution, and a distinction that trips people up because the $300,000 figure sounds like it should come with a tax benefit beyond the one it already has.
Treating "downsizer" literally and assuming a smaller or cheaper home has to be bought afterwards. It doesn't, and plenty of eligible clients don't buy another home at all.
Contributing against the wrong figure, using the sale price rather than the actual proceeds received, or not accounting for a jointly owned property correctly when working out each spouse's share.
Not checking the age pension and total super balance consequences until after the money has already gone into super, when the planning window to do anything differently has closed.
How It Compares With Other Ways to Add to Super
The downsizer contribution sits alongside several other mechanisms that get money into super outside the standard concessional cap, and clients are often weighing more than one at the same time.
The First Home Super Saver Scheme works in the opposite direction, using super to help get money out for a first home deposit, rather than putting a home sale into super, and tends to suit a completely different stage of life, though the two sometimes come up in the same family conversation when parents and adult children compare notes.
The government super co-contribution rewards lower and middle-income earners who make their own after-tax contributions, topping them up by up to $500 a year, which is a modest but genuinely free addition that downsizer-eligible clients sometimes forget they can still use in the same year.
The spouse super contribution tax offset works differently again, giving the contributing spouse a tax offset of up to $540 for building up a partner's lower super balance, which can be worth stacking alongside a downsizer contribution rather than choosing between them.
None of these compete directly with the downsizer contribution – they apply to different amounts, different ages and different sources of money – but we generally find it's worth looking at the full picture in the same conversation rather than treating a home sale and a regular contribution strategy as unrelated decisions.
What Sole Traders and Self-Funded Retirees Should Think Through
For a sole trader planning to wind down a business that was also run from home, the main residence test is where things can get complicated rather than straightforward. If part of the property was claimed as a place of business, a home office claimed at a fixed rate, or a larger area set aside for trade purposes, the main residence exemption may only apply to part of the gain, and the downsizer contribution calculation follows that same proportion rather than treating the whole sale as eligible.
For self-funded retirees who've already maximised their concessional contributions for the year, or who are past the point where further large non-concessional contributions are realistic without a work test, the downsizer rule is often one of the few remaining ways to move a significant lump sum into the concessional tax environment of super in one step. The trade-off, as above, is usually less about tax and more about how it interacts with the age pension and future total super balance thresholds, which is why we'd rather have this conversation with a client before a contract of sale is signed than review it afterwards.
How Baron Tax & Accounting Can Help You Plan This
Working out whether a specific property and ownership history actually meets the ten-year and main residence tests, timing the 90-day form submission correctly with the right fund, and modelling what the extra balance does to future caps or an age pension assessment is exactly the kind of planning our registered tax agents at Baron Tax & Accounting handle for clients across Australia from our Rochedale South office. We look at the downsizer contribution alongside your broader retirement and tax position rather than as an isolated form to fill in, because the form itself is the easy part – the eligibility and the consequences are where the real decisions sit.
If you're planning a home sale in the next year and want to know whether a downsizer contribution makes sense for your circumstances, get in touch with Baron Tax & Accounting before you sign anything, and we'll work through it with you.

Frequently Asked Questions
Can I make a downsizer contribution if I only owned part of the home?
Generally yes, provided the combined ownership period across you and your spouse reaches ten years and the sale still qualifies for at least a partial main residence exemption, though your own contribution is limited to your share of the proceeds, not the full sale price.
Does a downsizer contribution affect my age pension?
It can. Money that sits in your home is generally not assessed under Centrelink's asset test, but once it moves into super, especially into an account-based pension, it's assessed differently, so it's worth checking your position with Services Australia or an adviser before you sell.
Can both my spouse and I contribute from the same home sale?
Yes. Each of you can contribute up to $300,000 from the one sale, so up to $600,000 combined, even if only one of you is on the title, as long as you both meet the age and ownership requirements separately.
What happens if I miss the 90-day deadline?
In most cases the fund can no longer accept it as a downsizer contribution once the window closes, and the ATO only grants extensions in limited circumstances that don't include fixing the age requirement, so this isn't a deadline to leave until the last week.
Do I have to buy a smaller home afterwards?
No. Despite the name, there's no requirement to buy another home at all, let alone a smaller or cheaper one.
Is the downsizer contribution tax deductible?
No. It's made from after-tax sale proceeds and there's no deduction available for it, which is one of the main differences between a downsizer contribution and a concessional contribution.
