Retirement Financial Planning in Australia: How Downsizer Contributions and Non-Concessional Strategies Can Boost Your Super Before You Stop Working

The kids have moved out, the spare rooms are full of boxes and the garden takes up every second weekend. For many Australians in their late fifties and sixties, selling the family home and moving somewhere smaller starts to make sense. What fewer people realise is that the sale can also be one of the best chances they’ll ever get to boost their super.

Two strategies do much of the heavy lifting here: downsizer contributions and non-concessional contributions. Used together, and timed well, they can move a large amount of money into the low-tax super environment before you retire. This step-by-step guide explains how each works and how they fit into wider retirement financial planning.

Please note this is general information only and doesn’t consider your personal circumstances. Contribution rules and caps change, so check current limits with the ATO or a licensed adviser before acting.

Step 1: Understand Why Super Is Worth Topping Up

Super is taxed lightly compared with most other places you can hold money. Investment earnings in the accumulation phase are generally taxed at up to 15%. Once you retire and move your balance into a retirement income stream, such as an account-based pension, earnings on that money are generally tax-free, up to the transfer balance cap.

That’s why moving money from a bank account or an investment property into super before retirement can make a meaningful difference over time. The same returns, taxed less, compound faster. Good retirement financial planning starts by working out how much of your wealth sits outside super and whether moving some of it in would help.

Step 2: Check Whether You Qualify for a Downsizer Contribution

The downsizer contribution lets eligible people put up to $300,000 each from the sale of their home into super. For a couple, that’s up to $600,000 combined.

To qualify, you generally need to be 55 or older, and you or your spouse must have owned the home for at least 10 years. The home must be in Australia, and it needs to have been your main residence at some point, so that the sale qualifies for at least a partial main residence capital gains tax exemption.

Despite the name, you don’t actually have to buy a smaller home. You can move into a rental, retirement village or anywhere else. And there’s no upper age limit or work test.

Step 3: Get the Timing and Paperwork Right

This is where people trip up. The contribution generally has to be made within 90 days of receiving the sale proceeds, which is usually the settlement date. Miss that window and you may lose the chance, unless the ATO grants an extension.

You also need to give your super fund the ATO’s downsizer contribution form before or at the time you make the contribution. Without it, the fund may treat the money as a regular non-concessional contribution, which could push you over your cap.

The downsizer contribution can only be used once, from the sale of one home. If you’re planning several property moves, think carefully about which sale to use it on.

If you’re in Queensland, booking in for retirement planning in Brisbane before the house goes on the market gives you time to line up the paperwork and the settlement date.

Step 4: Layer In Non-Concessional Contributions

Non-concessional contributions are after-tax contributions, money you’ve already paid tax on. The annual cap is currently $120,000.

If you’re under 75, you may be able to use the “bring-forward” rule, which lets you contribute up to three years’ worth of caps at once. That’s up to $360,000 in one go. However, eligibility depends on your total super balance. You can’t make non-concessional contributions once your balance reaches the general transfer balance cap (currently $2 million), and the amount you can bring forward reduces as you get closer to that limit.

Here’s the key point: downsizer contributions don’t count towards your non-concessional cap, and they aren’t restricted by your total super balance. That means a couple who qualify could potentially combine both strategies and move a large sum into super in a relatively short time.

Step 5: Think About Who Holds the Money

For couples, it’s often worth considering how super is split between you. Each person has their own transfer balance cap, so holding balances more evenly can increase how much you can eventually move into the tax-free retirement phase.

Spouse contributions, contribution splitting and directing the downsizer contribution to the partner with the lower balance are all ways to even things out. The best approach depends on your ages, balances and when each of you plans to stop working.

Step 6: Check the Effect on the Age Pension

Your family home is exempt from the Age Pension assets test. Once you sell it and put the proceeds into super, that money is generally counted once you reach Age Pension age, even though super in the accumulation phase is ignored before then.

For some people this has little impact, because their assets are already above the pension thresholds. For others, it could reduce or remove their pension entitlement. Running the numbers before you sell is the only way to know which group you’re in.

Don’t forget about other costs, too. Stamp duty on a new home, moving costs and any renovations all come out of the sale proceeds before you decide how much goes into super.

Step 7: Bring It Together With Professional Advice

Each of these strategies has rules, deadlines and trade-offs. Combining them well means looking at your whole picture: your property, super balances, other investments, tax position, pension eligibility and the lifestyle you want after work.

Lifelong Wealth is one financial planning firm that helps clients map out these decisions, from contribution strategies to retirement income. Whoever you speak with, make sure they’re listed on ASIC’s Financial Advisers Register.

Aim to start these conversations six to twelve months before you plan to sell. That gives you time to sort out contribution timing, paperwork and the order of each step without rushing.

One last tip: talk to an adviser before you sign a sale contract, not after. Settlement dates, contribution windows and cap limits are much easier to manage when they’re planned from the start, and getting the order right could make a lasting difference to how comfortable your retirement turns out to be.
