Downsizer Contributions: Turning a Home Sale Into a Super Boost

Selling a long-held home after 55 unlocks a super contribution pathway most other rules don’t offer: up to $300,000 per person, completely outside the normal contribution caps.

For anyone whose FIRE plan involves downsizing later in life — or who inherits a parent’s downsizing decision as part of a broader family financial picture — this is one of the largest single contribution opportunities in the system.

Downsizer contributions are unusual among super rules in having no income test, no work test, and no interaction with the concessional or non-concessional caps.

How Downsizer Contributions Work

Australians aged 55 or over can contribute up to $300,000 each ($600,000 per couple) from the proceeds of selling an eligible home into super, regardless of the normal concessional or non-concessional caps, and regardless of the total super balance test that blocks other non-concessional contributions above $2.1 million. The contribution must be made within 90 days of settlement and reported to the fund on the correct ATO form. The ATO’s downsizer super contributions page has the current form and the full eligibility checklist.

Downsizer contributions don’t require the home to be genuinely “downsized” in size or value — the name describes the typical use case, not a legal requirement. Selling a $2 million home and buying another $2 million home still qualifies, provided every other condition is met.

The Eligibility Conditions That Actually Matter

The property must have been owned for at least ten years and have qualified for the main residence capital gains tax exemption (in full or in part). Only one downsizer contribution can be made per person, per lifetime, per eligible sale — it isn’t a repeatable strategy across multiple property sales. Both members of a couple can each make downsizer contributions from the same sale, which is how the combined $600,000 figure is reached — it isn’t a single joint contribution.

Why This Sits Outside the Normal Cap System

Every other significant super contribution — concessional, non-concessional, carry-forward — interacts with either an annual cap or the total super balance test. Downsizer contributions do neither, which is precisely why they matter to people already near or above the general transfer balance cap who would otherwise be locked out of contributing more. For a FIRE plan that includes eventually selling a family home, downsizer contributions can meaningfully accelerate the super side of a two-portfolio strategy in a single transaction. Moneysmart’s downsizer contribution guide covers the same rules in plain language, alongside the interaction with the Age Pension assets test worth checking before relying on this strategy.

Downsizer contributions also don’t require actually retiring — someone could sell, contribute, and keep working, which decouples the super-boost decision from the FIRE date itself.

Frequently Asked Questions

Do I need to buy a smaller home to use the downsizer contribution?

No — despite the name, there’s no requirement to actually downsize. The rule applies to the sale of an eligible main residence regardless of what happens next with the proceeds.

Does the downsizer contribution count toward my concessional or non-concessional caps?

No — it sits entirely outside both cap systems, which is the specific feature that distinguishes it from every other contribution type.

Can I use the downsizer contribution more than once?

No — it’s limited to one contribution per person across a lifetime, tied to a single eligible property sale.
