Timing a Property Sale Around the Year Your Income Stops

01 The year that counts is the contract year

A capital gains tax event happens when the contract is entered into, not at settlement. A contract signed in June and settled in August falls in the earlier financial year, which is a lever worth knowing about and one that is easy to use.

The gain is reduced by the 50% discount where the asset has been held for more than twelve months, and the discounted amount is added to your assessable income for that year.

Because it is added rather than taxed separately, it stacks on top of salary, rent, interest and everything else. The relevant rate is therefore the rate on the top of your income in that year, not your average rate.

Capital losses are applied before the discount, which is why realising a loss in the same year is worth more than realising it later — the ordering is set out in the loss harvesting post.

The cost base is more than the purchase price. It includes stamp duty, legal fees, the buyer's agent, capital improvements, and selling costs including agent commission and marketing, less any capital works deductions already claimed. Assembling it properly is frequently worth tens of thousands and is done from documents that have to have been kept.

Where the property was ever your home, the gain is apportioned rather than fully assessable, and the six-year absence rule can remove it entirely for a period. That calculation comes before everything in this post, because it changes the size of what is being timed.

02 What retiring does to the rate

A salary of $140,000 puts every dollar of a discounted gain at the top marginal rate that applies to it. With no salary, the first band of the gain is absorbed by the tax-free threshold and the lower brackets before the higher rates apply.

For a moderate gain the difference is close to the full difference in rates. For a very large gain the effect is smaller in proportion, because the gain itself fills the brackets — which is the correction to the simple version of this advice.

Timing across two financial years can help where a property is held jointly or where more than one asset is being sold. Spreading realisations across years uses more than one set of brackets and is one of the few genuinely reliable tactics here.

Joint ownership halves the problem mechanically. A property held equally by two people produces two gains against two sets of brackets, so the effective rate is lower than the same gain in one name — and the difference is largest where one partner has retired and the other has not. Changing the ownership shortly before a sale does not help, because the transfer is itself a capital gains event.

Superannuation is the other absorber. A concessional contribution in the year of sale reduces assessable income directly, and unused carry-forward cap can make that contribution much larger than the annual cap — see the catch-up contributions guide.

Selling before or after the income stops

	While working	After retiring
Rate applied to the gain	Stacked on your salary	Stacked on a much smaller base
Concessional cap available	Reduced by employer contributions	Usually the full cap, plus carry-forward
Work test for a deductible contribution	Not an issue	Applies from 67
Age Pension effect	None, before Age Pension age	Proceeds are assessable and deemed
Rent lost	Replaced by salary	Replaced by nothing until the proceeds are invested
Market risk while waiting	Borne for longer	Already realised

04 What the Age Pension does to the answer

Before Age Pension age, none of this touches Centrelink. A sale at 62 is a tax decision only, which is part of why the window between stopping work and reaching 67 is so valuable.

After Age Pension age, the property was already an assessable asset and the proceeds are too, so the assets test does not change much. What changes is the income test: rent is replaced by deemed income on the proceeds, which may be more or less than the rent was.

The larger Centrelink consideration is what you do with the money. Proceeds spent on the principal home leave the assets test entirely, as covered in the home exemption reference, which is a legitimate use that a sale makes possible and holding does not.

Losing the rent is the part that gets overlooked. A property producing net rent is producing assessable income that also counts under the income test, and the proceeds produce deemed income instead. For a property with a low yield relative to its value, deeming on the proceeds can assess more income than the rent ever did.

Gifting the proceeds to children does not work for five years, under the deprivation rules in the gifting reference. Families frequently plan a sale around exactly that intention.

05 The risks of waiting

The market is the obvious one. Holding an asset for three more years to save tax is a decision to bear three more years of price risk on a single, undiversified, illiquid asset, and the tax saving can be smaller than a moderate price move.

Holding costs are the second. Rates, insurance, maintenance, land tax and any interest continue, and for a property that is negatively geared the deduction is worth much less once the salary has stopped — the rate that made the strategy work has gone.

Tax law risk is the third and the least predictable. The CGT discount and the treatment of rental losses have both been the subject of repeated policy proposals, and a plan that depends on them being unchanged in five years is making an assumption rather than a calculation.

Against all of that, the tax saving from selling in a low-income year is large, knowable and within your control. That is the asymmetry that usually decides it.

There is also a liquidity risk that only shows up at the wrong time. A property takes months to sell in a good market and can be unsellable at any acceptable price in a bad one, so a plan that requires the sale to happen in a particular year is exposed to the one asset class that cannot be sold in a week. Households that need the proceeds to fund the first years of retirement should start the process earlier than the tax answer alone suggests.

06 What I would actually do

Work out the discounted gain first, then model the tax in each of the specific years you could realistically sell. Three numbers settle this, and most people never calculate the second and third.

If the gap between the best and worst year is large and the property is not at risk of a specific decline, waiting for the low-income year is worth doing. If the gap is small, sell when the property should be sold on its own merits.

Then decide the contract date deliberately rather than letting the agent's campaign decide it. A property listed in May and selling well can be contracted in June or in July, and where the two years have materially different rates that is a choice worth making before the campaign starts rather than during the negotiation.

Use the year of sale for a concessional contribution, with carry-forward cap if your total super balance allows it. That is the most reliable way to reduce a one-off spike in assessable income, and it moves the money into a lower-tax environment at the same time.

It is commonly assumed that the discount makes the timing unimportant because the gain is halved either way. It is not — the discount changes the amount, and your marginal rate changes what happens to it, and only one of those two is under your control.
