Selling to downsize: how the Age Pension protects your home sale proceeds (and the catch most people miss)

Downsizing is one of the most common moves in retirement — sell the big family home, buy something smaller and easier to manage, and free up some cash. But there's almost always a gap between selling the old place and settling, building, or renovating the new one, and during that gap the sale proceeds sit in a bank account. A large lump sum in the bank is exactly the kind of thing that can wreck an Age Pension — the means-tested government payment administered by Services Australia. The good news is that Centrelink has a rule to protect you through that gap. The catch is that the protection is narrower than most people assume, it has a deadline, and it doesn't make the money disappear entirely. Understanding the detail is the difference between a smooth downsize and an unpleasant surprise on your next pension statement. This article is general information only, not personal advice.

What problem does the rule solve?

Your family home is an exempt asset — it doesn't count in the Age Pension assets test. The moment you sell it, though, that exempt asset turns into cash, which normally is assessable. Without a special rule, selling an $800,000 home would dump $800,000 of assessable assets into your means test overnight, potentially cancelling your pension right when you're mid-move and most need the stability. The home sale proceeds rule prevents that whipsaw — provided you're selling in order to secure another home to live in.

What does the exemption protect?

When you sell your principal home and intend to use the proceeds to buy, build, rebuild, repair, or renovate another home that will become your principal home, the portion of the proceeds you intend to use is exempt from the assets test (DSS Social Security Guide 4.6.3.90, https://guides.dss.gov.au/social-security-guide/4/6/3/90). Two things are worth underlining straight away. First, it's only the portion you genuinely intend to use for the new home that's protected — not automatically the whole sale price. If you sell for $800,000 and intend to spend $600,000 on the new place, it's the $600,000 that's exempt; the other $200,000 is assessable from the date of sale (Services Australia, https://www.servicesaustralia.gov.au/real-estate-assets). Second, the rule covers more than just buying — building, rebuilding, repairing, and renovating all count, which matters for knock-down-rebuilds and major renovations. A useful related point: you continue to be assessed as a homeowner throughout the exemption period, so the homeowner asset thresholds apply to your other assets.

What is the time limit?

The exemption doesn't last forever. For homes sold on or after 1 January 2023, it applies for up to 24 months from settlement (DSS Social Security Guide 4.6.3.90, https://guides.dss.gov.au/social-security-guide/4/6/3/90) — a window that was extended from the old 12-month rule in recognition that buying, and especially building, can take a long time. In limited circumstances — where you haven't been able to buy, build, rebuild, repair or renovate within the 24 months, delays are genuinely beyond your control, and you've made reasonable attempts — the period can be extended by a further 12 months, to a maximum of 36 months (DSS Social Security Guide 4.6.3.90, https://guides.dss.gov.au/social-security-guide/4/6/3/90). If you reach the end of the window with the money still unspent, the proceeds you're holding become fully assessable.

What is the catch most people miss — does deeming still apply?

Here's the part that surprises people. The exemption is an assets-test exemption only. The same proceeds are still assessed under the income test through deeming — the rule that treats financial assets as earning a set rate of income regardless of what they actually earn. The softener is that, during the exemption period, the protected proceeds intended for the new home are deemed at only the lower deeming rate — currently 1.25% (Services Australia; DSS Social Security Guide 4.4.1.10, https://guides.dss.gov.au/social-security-guide/4/4/1/10) — rather than the 3.25% upper rate that would otherwise apply to larger balances. Any extra proceeds you're not putting toward the new home are deemed at the regular rates. So the money isn't invisible: it still generates a deemed income figure that counts in your income test, just at a concessional rate on the protected portion.

What this means in practice depends on which test currently limits your pension. If you're assets-tested, the exemption is enormously valuable — your largest chunk of cash drops out of the test that's actually constraining you. If you're income-tested, the benefit is more modest, because deeming on the proceeds continues regardless; the lower rate helps, but the money still shows up in the test that matters for you.

What do worked examples look like?

These show the rule working — and its edges. They are illustrative only — not personal advice, and Services Australia determines your assessment.

Margaret, a single age pensioner, sells her home for $800,000. She intends to spend $600,000 on a smaller unit and keep $200,000 for living costs. On these facts the $600,000 she intends to use is exempt from the assets test for up to 24 months and is deemed at only the lower 1.25% rate under the income test during that window (DSS Social Security Guide 4.6.3.90, https://guides.dss.gov.au/social-security-guide/4/6/3/90), while the $200,000 she's keeping is assessable from the date of sale and deemed at the normal rates, because she doesn't intend to use it for the new home. If Margaret buys the unit ten months later, the exemption has done its job: her pension stayed stable through the move. On these facts, because she was assets-tested to begin with, sheltering that $600,000 from the assets test is the difference between a disrupted pension and a steady one — so making her genuine intention clear to Centrelink and buying within the window is generally rational.

Robert and Helen, a retired couple, sell their home for $1.1 million and decide to knock down and rebuild on a block they've bought, intending to put $750,000 into the new home. On these facts the $750,000 intended for the rebuild is assets-test exempt and deemed at the lower 1.25% rate, and they remain assessed as homeowners while they build. But construction runs long — council delays and a builder going under push them past the 24-month mark with the home unfinished. On these facts, because the delays are genuinely beyond their control and they've made reasonable attempts to get the build done, it is generally rational for them to apply to Centrelink early, with documentation, for the further 12-month extension that takes the maximum exemption to 36 months (DSS Social Security Guide 4.6.3.90, https://guides.dss.gov.au/social-security-guide/4/6/3/90). If they let the 24 months lapse without raising it, the unspent $750,000 would become fully assessable and their pension would be reassessed — so watching the clock is the whole game.

What should you actually do?

A few practical steps make the difference. Tell Centrelink when you sell, and declare how much of the proceeds you intend to use for the new home, because the exemption isn't automatic — it depends on your stated, genuine intention, and Centrelink may ask for evidence. Keep the protected portion identifiable rather than assuming your whole bank balance is exempt; only the intended-to-use part is. Watch the clock and track the 24-month deadline, and if delays are outside your control, raise the possibility of an extension with Centrelink early, with documentation. Plan for the deeming, since the proceeds still count under the income test and your pension won't be completely unaffected. And get advice on any surplus, because the money you're not putting into the new home is often the bigger means-test issue — and what you do with it, including super strategies, is worth proper advice (our companion piece on when to claim the Age Pension covers the age-gap super angle). Downsizing can be one of the smartest financial moves in retirement; the sale proceeds rule is there to make the transition smoother, but like most Centrelink concessions, it rewards the people who understand its edges.
