Save $300,000: Downsizer contribution checklist for Australians 55+

Save $300,000: Downsizer contribution checklist for Australians 55+

If you're 55 or older and selling your home, you can contribute up to $300,000 of the sale proceeds into super as a downsizer contribution, with couples potentially adding a substantial combined amount. The catch is timing: the contribution has to land in your fund within 90 days of settlement, using the ATO's approved form. Before you sign anything, check your fund will accept it and whether the sale could affect an Age Pension assessment.

TL;DR:

  • The maximum downsizer contribution per person is limited to the sale proceeds, with couples able to combine their limits if they sell jointly owned property.
  • The contribution must be made within 90 days of settlement, with a proper form submitted before or at the same time as the funds are received.
  • Eligibility requires at least 10 years of ownership by the seller or spouse, and the property must qualify as a main residence in Australia.
  • Making the contribution earlier than modeling the pension impact can prevent unexpected reductions in Age Pension entitlement.
  • The contribution avoids the 15% super tax but impacts the super balance and transfer balance cap, potentially affecting future pension benefits.

What is a downsizer contribution?

A downsizer contribution lets you put money from selling your home into super, outside the usual annual caps that trip up most people over 55. It's a once-only concession. Once you've used it, you can't use it again for a different property, or for a later part sale of the same one, according to SuperGuide.

The rule exists because older Australians often hold most of their wealth in the family home, with little room left under the standard non-concessional contribution limits to move that value into super. Downsizer contributions sidestep that bottleneck entirely.

A few things worth knowing upfront:

  • You don't actually have to downsize. MoneySmart confirms you can buy a bigger place, or no place at all, and still qualify.
  • The contribution sits outside your concessional and non-concessional caps, but it still counts towards your total super balance.
  • It's available even if you're retired, no longer working, or past the age where compulsory contributions apply, which is precisely when other contribution paths often close off, as SuperGuide notes.

Are you eligible for a downsizer contribution?

Eligibility hinges on four conditions, and missing any one of them invalidates the whole contribution.

  • Age: You must be 55 or older at the time you make the contribution. There's no upper age limit, unlike most other super contributions.
  • Ownership period: You or your spouse must have owned the property for at least 10 continuous years before the sale.
  • Property type: It needs to be a residential property in Australia that generally qualifies, in whole or part, for the main residence capital gains tax exemption.
  • First and only use: You cannot have made a downsizer contribution from a previous home sale.

The most overlooked detail is that ownership doesn't need to sit in one name. If your spouse has owned the home for the full 10 years but you've only recently been added to the title, you may still qualify because the rule looks at either spouse's ownership period, per the ATO.

The number that matters: a specific limit applies per eligible person for downsizer contributions, meaning a couple selling a jointly owned home can potentially move a significant combined amount into their retirement savings from one sale.

How much can you contribute, and what limits the amount?

The cap per eligible person applies, but the real ceiling in many cases is the sale price itself.

  • There is a maximum contribution per eligible person.
  • Couples may combine their individual limits up to the total sale proceeds.
  • Your downsizer contribution can never exceed the total proceeds from the sale.
  • These contributions don't reduce your concessional or non-concessional caps for that year, so you can still make other super contributions on top, subject to those caps.

That last point is where the strategy gets interesting for pre-retirees still working part time. You could top up super through salary sacrifice or personal deductible contributions in the same financial year, then add a downsizer contribution on top, without either eating into the other's limit.

How do you make a downsizer contribution?

The process is straightforward, but the sequencing matters more than most how to sell property in any condition in Australia guides let on.

  1. Contact your super fund before settlement. Confirm they'll accept downsizer contributions and, if you need one, get an account opened. Not every fund handles them the same way.
  2. Complete the Downsizer contribution into super form (NAT 75073). This is the ATO's approved form, and it has to reach your fund before or at the same time as the money does, not after, according to Financial Planning with Alan.
  3. Make the contribution within 90 days of receiving the sale proceeds. This is the hard deadline covered in more detail below.
  4. Use a separate form for each fund or each payment if you're splitting the contribution across multiple funds or making it in instalments.
  5. Check your fund's confirmation and, later, your ATO online services record to make sure the contribution was reported correctly.

Pro Tip: Get the NAT 75073 form to your fund on settlement day, not after the money clears. Funds have been known to reject late paperwork even when the 90-day window technically hasn't closed, because their internal processing cut-offs are tighter than the ATO's own deadline.

What is the 90-day rule, and can you get an extension?

The 90-day clock starts when you receive the sale proceeds, usually the settlement date, not the contract signing date. "Received" generally means the funds have been made available to you.

  • Extensions are possible if applied for before the 90 days expire.
  • Grounds for extension typically involve genuine delays outside your control.
  • The ATO will not extend the deadline to help you meet the age requirement.
  • A common mistake is miscalculating the start of the 90-day period due to mixing funds or delays in paperwork.

How is a downsizer contribution taxed, and does it affect your pension?

Downsizer contributions avoid the 15% contributions tax that applies to most super deposits, and you can't claim a tax deduction for them either, since they're treated as a distinct category rather than a personal contribution.

  • Total super balance: The full amount counts towards your total super balance as at 30 June, which can affect your eligibility to make future non-concessional contributions if your balance climbs near the relevant threshold.
  • Transfer balance cap: If you later move the money into a retirement-phase income stream, it counts against your transfer balance cap, according to MoneySmart.
  • Age Pension impact: Selling your main residence changes how Centrelink treats that asset. A home is generally exempt from the assets test while you live in it, but once it's sold and the proceeds sit in super or cash, they typically become assessable, which can reduce your Age Pension entitlement, MoneySmart notes.

Here's the trade-off in numbers: moving $300,000 from an exempt home into an assessable super balance can shift your position under the assets test enough to reduce or eliminate a part Age Pension, depending on your other assets. Check current thresholds with Services Australia before you commit, because this is the single most common surprise homeowners report after making the contribution.

What happens after you make the contribution?

Your fund has to report the contribution to the ATO, generally within 10 business days for funds other than SMSFs, and it should appear in your ATO online services account labelled "Proceeds of primary residence disposal," per the ATO.

  • Log into ATO online services through myGov a few weeks after your fund confirms receipt, and check the contribution is labelled correctly.
  • If it's missing or mislabelled, contact your fund immediately. Don't wait for tax time to sort it out.
  • If the ATO determines the contribution was never eligible, your fund will be told, and the amount may be reclassified as a personal non-concessional contribution or returned to you outright.
  • A reclassified amount could then push you over your non-concessional cap for the year, triggering excess contributions tax, which is a far worse outcome than the paperwork delay that usually causes the problem.

Worked examples: how the numbers play out

  1. Single seller: Margaret, 67, sells her home for $280,000. Even though the per-person cap is $300,000, her contribution is limited to the sale proceeds, so she can contribute a maximum of $280,000.
  2. Couple, one name on title: Tom and Elena have owned their home together for 15 years, but only Tom is on the title. Both can still qualify under the ownership rules, provided Elena's spousal connection meets the ATO's ownership test. They sell for $700,000, and each contributes $300,000, using $600,000 of the proceeds, leaving $100,000 outside super.
  3. Partial sale, split payments: David sells a share of his property for $200,000 now and expects a further payment later. He contributes the first $200,000 within 90 days of receiving it, lodging a separate NAT 75073 form, then repeats the process for the second payment when it arrives, keeping each 90-day window tracked independently.

How modelling clarifies the downsizer decision

Deciding whether to make a downsizer contribution isn't just a super question. It's a retirement income question, a tax question, and often a pension question, all tangled together.

Useful modelling weighs the sale proceeds, any capital gains tax exposure on non-exempt components, the effect on your Age Pension means test, and what happens to the transfer balance cap if you eventually shift the money into retirement phase. Change the timing of the contribution or where the funds sit afterwards, and the outcome on your pension entitlement can shift meaningfully, since AlphaIQ's modelling work shows these interactions are more sensitive to sequencing than most people expect.

  • Compare "contribute now, draw a pension later" against "wait and contribute next financial year" if your circumstances allow it.
  • Test how much of your $300,000 you actually need in super versus keeping outside for accessibility.

Pro Tip: Run the numbers before you sign the ATO form. Once a contribution is made, undoing it involves your fund, the ATO, and potentially amended tax returns. Model it while you can still change your mind.

What I'd tell a homeowner weighing this decision

Most people treat the downsizer contribution as a super question. It's really a sequencing question. The paperwork rarely trips people up. What trips them up is contributing first and checking the pension impact later, when the only options left are unwinding a contribution or living with a reduced Age Pension they didn't see coming.

The order I'd follow: confirm fund acceptance, model the pension and transfer balance cap effects, then lodge the NAT 75073 form, then transfer the money. Not the reverse. And always verify the ATO's online record within a month, because a mislabelled contribution sitting quietly against your non-concessional cap is the kind of error that only surfaces at tax time, when it's harder to fix.

Model your downsizer scenario before you commit

A downsizer contribution is a one-shot decision with tax, super, and pension consequences that don't reverse easily, so it pays to see the numbers before you sign the ATO form. AlphaIQ's Super Calculator is built for exactly this kind of scenario testing. It models how a $300,000 or $600,000 downsizer contribution changes your projected retirement income, how it interacts with your transfer balance cap if you move funds into pension phase, and what the flow-on effect looks like for Age Pension eligibility under the assets test.

It won't replace a conversation with a licensed adviser for genuinely complex cases, joint ownership disputes, blended family estates, or overlapping pension entitlements, for instance. But for most homeowners weighing whether to contribute $200,000 now or $300,000 after a further sale, seeing the retirement income projection side by side with the pension impact makes the trade-off concrete instead of theoretical. Head to the calculator, enter your expected sale proceeds and current super balance, and model your own numbers before you complete the NAT 75073 form.
