If you've owned an investment property for years and retirement is getting closer, it's natural to wonder whether that money would be better off in super. 

You can put money from the sale into super, but there are limits on how much goes in. Once it's there, you generally can't take it out until you meet a condition of release, such as retiring after your preservation age or turning 65.

The 2026 Federal Budget has added to the question, because it changes how property is taxed outside super from 1 July 2027. Here's what you need to know:

• Super funds aren't covered by the Budget's capital gains and negative gearing changes. So from 1 July 2027, tax inside super compares differently with owning property in your own name. It doesn't change the capital gains tax on selling your own property.
• You generally can't move a rental you already own into super. The usual route is to sell it and contribute some of the cash.
• The main way in is through the yearly contribution caps. In 2026–27 that's up to $130,000 a year that you don't claim a tax deduction for, or up to $390,000 in one go if you can use the next two years' limits early.
• The downsizer contribution generally needs the property to have been your home. It lets you add up to $300,000 each, outside the caps, but a property you've only ever held as a rental generally won't qualify.
• The Budget didn't change how much you can put into super.
• Capital gains tax still applies to the sale, and the date you sign the contract can matter.

The rest of this guide explains each point, so you can go into a conversation with your accountant or financial adviser knowing what to ask.

How much can I put into super from the sale?

For most rental property sales, there are three main ways to get the money into super, and each has its own limit.

After-tax contributions

These are contributions you don't claim a tax deduction for, such as savings or money from a sale, and your fund doesn't tax them again. Putting sale money in this way doesn't reduce the capital gains tax you owe on the sale. The bring-forward rule lets you put in up to three years' worth at once.

How much you can bring forward depends on your total super balance on the previous 30 June. That's an ATO measure of everything you hold in super, which can differ from simply adding up your account statements.

If you've already used the bring-forward rule in the past two years, your limit is lower until that period ends.

Before-tax contributions

These usually come from your employer or through salary sacrifice. You can also put in money from your own savings and claim it as a tax deduction. It then counts towards the $32,500 cap and is taxed at 15 per cent in your fund, and the deduction lowers your taxable income for that year. If that's the year you sell, it's worth asking your tax agent how it works with your capital gain.

To claim the deduction, you'll need to send your fund a notice of intent and get its acknowledgement. Do this before you lodge your tax return for that year (or by the end of the next financial year, if that comes first). Also send it before you withdraw any of the money, roll it over to another fund or start a pension with it. Otherwise you could lose some or all of the deduction.

A few other things to check:

• The deduction can't create or add to a tax loss, so it's only useful up to your taxable income for the year.
• If you're 67 to 74, you'll need to meet a work test (or qualify for an exemption from it) to claim the deduction.
• If your income for Division 293 purposes plus your before-tax contributions is more than $250,000, an extra tax called Division 293 can apply. The ATO notes this can happen for a single year when you make a capital gain, so the year you sell is worth checking with your tax agent.

Downsizer contributions

If you're 55 or older, you may be able to put up to $300,000 from the sale of a home into super without it counting towards your caps. If you're a couple, you can each contribute up to $300,000, as long as the total isn't more than the sale proceeds.

Here's the catch for investors: the sale must qualify, at least partly, for the main residence exemption from capital gains tax. In practice, that generally means the property was your home at some point while you owned it. The ATO's downsizer guidance gives the example of a rental the owner never lived in, and it doesn't qualify. A former home you later rented out can qualify, even if only part of the gain is exempt.

You'll also need to:

• have owned it for at least 10 years (you or your spouse)
• sell a home in Australia, not a caravan, houseboat or other mobile home
• contribute within 90 days of receiving the sale proceeds, usually at settlement
• give your fund the downsizer form before or when you contribute

You can only make downsizer contributions from one home sale. A downsizer contribution doesn't count towards your caps, but it does add to your total super balance.

How it could look: an example

This is a made-up example to show how the limits fit together. It isn't a recommendation.

Margaret is 62 and retired. She's selling a unit she bought in 2010 and has always rented out. She signs the contract in 2026–27. Her total super balance was $600,000 on 30 June 2026, she hasn't used the bring-forward rule in the past two years, and she hasn't made any other contributions this year. Her taxable income for 2026–27, including the capital gain, is well above $32,500.

• Downsizer: not open to her, because the unit was never her main residence, so no part of the gain is covered by the main residence exemption.
• After-tax contributions: her balance is under $1.84 million and she's under 75, so she could put in up to $390,000 at once using the bring-forward rule.
• Before-tax contributions: she's retired, so there are no employer contributions. She could put in up to $32,500 and claim it as a tax deduction, because her income is high enough to use it. Her balance is over $500,000, so she can't add unused cap from earlier years.

That's up to $422,500 contributed in 2026–27, before the 15 per cent tax her fund takes from the $32,500. Because the capital gain lifts her income that year, her tax agent would also check whether Division 293 applies. Anything beyond that stays outside super this year. If she claims the deduction, she'll need to send her notice to the fund before she withdraws any of that money or starts a pension with it.

Whether doing any of this suits Margaret depends on her income, her plans and the tax on her gain, which is where an adviser comes in.

What did the 2026 Budget change?

In short, the Budget changed how property is taxed outside super from 1 July 2027, and left the super contribution rules as they were. It was delivered on 12 May 2026, and its main property changes became law in June 2026.

If you already owned your rental before Budget night, the negative gearing change doesn't apply to it while you keep it.

The capital gains and negative gearing changes don't apply to super funds. A complying super fund still pays 15 per cent tax on its earnings, with a one-third discount on capital gains for assets held at least 12 months. 

Individuals, meanwhile, move to indexation for gains made from 1 July 2027, and a minimum 30 per cent tax applies to certain gains. That difference is worth understanding if you're comparing the two, alongside the limits on getting money into super and the tax your fund pays on contributions.

If you own a property on 1 July 2027 and sell later, the gain is split at that date, using the property's market value just before 1 July 2027. 

An alternative method for people who don't get a valuation is still being finalised, and the ATO will update its capital gains tax reform page as it's settled. If you expect to sell after that date, it's worth asking your accountant whether to get a valuation.

If you bought your property before 20 September 1985, its gains have been exempt from capital gains tax. That stays true for gains made before 1 July 2027, but gains made from that date will be taxed.

Will I pay tax when I sell?

Usually, yes. Capital gains tax isn't a separate tax: your net capital gain (after any capital losses and discounts) is added to your income for the year and taxed at your marginal rate. If you've owned the property for at least 12 months and you're an Australian resident, you can currently halve the gain before it's taxed. Different rules apply if you've been a foreign resident.

For property, the sale date for tax purposes is usually the date you sign the contract, not settlement. If you sign before 1 July 2027, today's rules apply to the whole gain. If you sign later, the part of the gain made from 1 July 2027 falls under the new rules, including, for certain gains, the minimum 30 per cent tax for individuals.

Once money is in super, the fund generally pays 15 per cent tax on its earnings, with a one-third discount on capital gains for assets held at least 12 months. Earnings on assets that support a retirement income stream (a pension paid from your super) can be tax-free.

When can I get the money back out?

Money in super is preserved, which means you usually can't withdraw it until you meet a condition of release. These include reaching your preservation age and retiring, or turning 65. Your preservation age depends on when you were born, and it's 60 if you were born on or after 1 July 1964. If you're 60 or older and have retired, you may already meet a condition of release.

If you haven't, it helps to be sure you won't need the sale money before then.

Could my super buy a property instead?

A self-managed super fund (SMSF) can buy property, but the rules are strict:

• The property must be held for the sole purpose of providing retirement benefits to the fund's members.
• If it's residential property, you, your family and other related parties can't live in it or rent it.
• The fund can't buy it from you, a relative or another related party, unless it's business real property (land and buildings used wholly and exclusively in a business) bought at market value. Business real property can then be leased to a related party at market rent.
• Since 10 August 2026, an SMSF can only borrow to buy real property if it's business real property, so generally not a rental home. It can still buy a home with its own money. Loans taken out before 10 August 2026, refinancing of those loans, and purchases where the fund had exchanged a binding contract before that date aren't affected. The ATO explains it on its SMSF borrowing changes page.
• The fund's investment strategy has to consider liquidity, so it can still pay its expenses and members' benefits.

ASIC's Moneysmart (July 2026) warns against feeling pressured into buying property through an SMSF, and to watch for sales tactics such as competitions, free flights to sales meetings or free meals. Advice on setting up an SMSF should come from someone authorised under an Australian financial services licence.

Questions to work through with your adviser

These rules interact, so it helps to have your answers to a few questions ready before you sit down with a licensed financial adviser or a registered tax agent:

• When will you need the money? Once it's in super, you generally can't take it out until you meet a condition of release.
• What was your total super balance on 30 June? It sets how much you can put in after tax.
• Was the property ever your home? If it was, a downsizer contribution may be open to you.
• How big is the gain, and when would the contract be signed? The tax rules change for gains made from 1 July 2027.
• What's your income in the year you sell? It affects the tax on the gain and on any contribution you claim as a deduction.
• Is your super balance close to $3 million? From 1 July 2026, Division 296 adds an extra 15 per cent tax on the share of earnings from the part of a balance above $3 million, and a further 10 per cent above $10 million. Both thresholds are indexed.

It's worth having that conversation before you sign a contract, because the contract date usually decides which tax rules apply to the sale.
