The kids' rooms have been empty for years. You shut the door on half the house over winter because heating it feels ridiculous. The gutters need doing again, the garden has become a second job, and somewhere at the back of your mind sits the thought that this place is now more work than home.
Then the other thought arrives, the one that stops the conversation: if we sold, where would the money actually go? Into the bank, earning very little, counted by Centrelink, quietly losing ground to the cost of living?
There is a rule built for exactly this moment, and it is one of the most generous in the superannuation system. It lets a couple move up to $600,000 from a home sale into super in a single hit, outside the usual contribution limits. It is called the downsizer contribution — and the name is a little misleading, because you do not actually have to downsize.
What the downsizer contribution actually does
If you are 55 or older at the time you make it, you can contribute up to $300,000 from the sale of your home into your super fund. Each member of a couple can do it, so $600,000 between you, and the home only needs to have been owned by one of you — it does not have to be in both names.
The one hard ceiling is the sale itself. Your combined downsizer contributions cannot exceed the total proceeds. If the house sells for $450,000, that is the most that can go in, however you divide it between you.
The Australian Taxation Office (ATO) sets the conditions, and they are short enough to check over a cup of tea:
- You are 55 or older when the contribution is made.
- You or your spouse owned the home for 10 years or more before the sale.
- It is a residential building in Australia that qualified, at least in part, for the main residence exemption from capital gains tax (CGT). Caravans, houseboats and mobile homes do not count.
- The contribution reaches your fund within 90 days of you receiving the proceeds — normally settlement day.
- You give your fund the ATO's downsizer contribution form (NAT 75073) before or at the time you contribute.
- You have not already made a downsizer contribution from another home.
Note what is not on that list. There is no requirement to buy a smaller home. There is no requirement to buy another home at all. You can sell up, move in with family, rent, or buy something grander, and the contribution still stands.
Why it sits outside the caps, and why that matters
This is the part that makes the downsizer rule genuinely unusual.
In 2026-27 the concessional (before-tax) contributions cap is $32,500 a year and the non-concessional (after-tax) cap is $130,000. Those are real constraints for anyone trying to move a lump sum into super late in their working life.
A downsizer contribution counts towards neither. It sits entirely outside both caps. For someone who has been dripping money in at $130,000 a year and watching the calendar, that is the difference between a three-year plan and a single afternoon's paperwork.
There is a second, quieter advantage. Normally, once your total super balance reaches the general transfer balance cap — $2.1 million from 1 July 2026 — your non-concessional cap drops to nil and you cannot make after-tax contributions at all. The downsizer contribution is not blocked by that test. A balance above the cap does not disqualify you.
Once the money is in, it is treated like any other super: taxed at concessional rates while it is invested, and potentially tax-free once it moves into a retirement income stream.
The traps worth knowing before you sign anything
The 90 days are counted from settlement, not from the day you decide. This is where most people come unstuck. The clock starts when you receive the proceeds, and 90 days disappears quickly in the middle of a move. The ATO can grant an extension in some circumstances, but it cannot extend the clock to fix an age problem — if you turn 55 after the window closes, no extension helps. Talk to your fund before the contract, not after the removalists have gone.
It still counts towards your transfer balance cap. Getting money in is not the same as getting it into a tax-free pension. When your super moves into retirement phase, the downsizer money counts towards that $2.1 million limit like everything else.
It is included in your total super balance at 30 June. That figure governs your eligibility for several other super rules, including future after-tax contributions and the catch-up concessional rules. A large downsizer contribution can close doors you were planning to walk through later.
You only get one. One downsizer contribution, from one home sale, in your lifetime. If you expect to sell again in a few years, it is worth thinking about which sale you want to use it on.
The age pension question nobody asks early enough
Here is the honest trade-off, and it deserves plain language.
Your family home is not counted under the age pension assets test. Your superannuation is — once you reach age pension age, which is 67 for everyone born on or after 1 January 1957. So moving money out of an exempt asset and into an assessable one can reduce your pension, or end it.
If you sell and intend to buy another home, Services Australia can exempt the portion of the proceeds set aside for that purchase from the assets test for up to 24 months, with a further 12 months possible in some circumstances — and during that period those funds are deemed at the lower rate only. But money you divert into super is not money set aside for a new home, and it does not get that shelter.
This is not a reason to avoid the downsizer contribution. For a self-funded retiree, or someone whose pension was always going to be small, the tax advantages usually win comfortably. For someone on a full pension with modest savings, the sums can run the other way. The point is simply that it is a calculation, not an automatic yes — and it is worth doing before you list the house, while you still have choices.
If you are behind, or not sure yet
Plenty of people reach their late fifties with a valuable home and a thin super balance. That is not a failure of planning; it is what happens when a mortgage, children and one or two career interruptions occupy three decades. The downsizer contribution exists precisely because the family home is where so much Australian wealth ended up.
If that is you, a few things are worth doing in the next month rather than the next year. Find out what your home actually sold for in the neighbourhood, not what you hope it is worth. Get your current super balance in front of you. Ask your fund whether it accepts downsizer contributions — most do, but not all. And if the age pension is part of your picture, get a Centrelink estimate on both scenarios before you commit to anything.
Rules in this area change with most budgets. The age threshold alone has come down from 65 to 60 to 55 in a handful of years. What matters is knowing the rule exists and roughly how it works, so that when the house conversation finally happens at your kitchen table, you are weighing a real option rather than guessing.
If you are working through the downsizing decision — the numbers, the timing, the pension consequences and the emotional side nobody warns you about — Downsizing Made Simple (2nd Edition) by Noel Whittaker walks through it step by step. It is $19.99, you can buy direct from the author, and you get both PDF and EPUB formats so it reads on whatever you already use.
