You’ve just sold the investment unit you bought in 2019. The settlement’s gone through, the proceeds are sitting in your account, and for a brief moment you’re feeling pretty good. Then your partner asks, “How much of that are we going to lose to tax?” and the glow fades. If you’ve ever sold an asset — shares, an investment property, even crypto — and then stared at the words “capital gain” on your tax return without fully understanding what they meant for your bank balance, you’re in the right place. The ATO’s 2023–24 data shows over 2.5 million individuals reported a net capital gain, contributing more than $23 billion to the taxable income pool that year. Capital Gains Tax Australia 2026 isn’t a separate tax but a slice of your income tax, and how much you pay depends on what you sold, how long you held it, and what other income you earned.
In this plain-English guide, I’ll walk you through exactly how CGT works, how to calculate a capital gain step by step, the 50% discount and main residence exemption that can slash your bill, and what happens when you sell shares, a property, or something a bit more unusual. You’ll also get practical tips to minimise CGT legally, and you’ll know where to use NeonPlay’s free tax calculator to see your exact position. Let’s pull apart the jargon and give you a clear picture.
What Is Capital Gains Tax and How Does It Work?
Capital gains tax is not a separate tax with its own rates — it’s part of your income tax, triggered when you make a profit from selling an asset. That profit, called a capital gain, gets added to your assessable income for the financial year in which the sale occurs, and it’s taxed at your marginal rate (plus the Medicare levy). You pay CGT on the gain, not the full sale price. So if you bought a rental property for $400,000 and sold it for $600,000, only the $200,000 difference is potentially taxable.
What Triggers a CGT Event?
A CGT event is ATO-speak for any transaction that brings about a gain or loss. The most common one is selling an asset, but it can also include giving it away, losing it, or even moving overseas and ceasing to be an Australian resident (deemed disposal). Assets subject to CGT include real estate (other than your main residence), shares, units in managed funds, cryptocurrency, collectibles (like art or jewellery), and business goodwill. Personal assets like your car, furniture, and the home you live in are generally exempt, as are assets acquired before 20 September 1985 — the day CGT was introduced in Australia.
How Capital Gains Are Taxed
When you lodge your tax return for the 2025–26 financial year, any net capital gain is added to your assessable income and taxed along with your salary, interest, and dividends. There’s no separate rate. If you earn $90,000 from your job and make a $40,000 capital gain, your total taxable income becomes $130,000, and you’ll be taxed according to the **Australia tax brackets 2026**. The effective tax on the gain itself depends on your marginal rate — for that $130,000, the gain pushes into the 30% and 37% brackets, so the tax bite could be around $10,500 including the Medicare levy, before any discount. Understanding your marginal rate is crucial, and our Australia tax brackets 2026 guide breaks down every threshold so you can see exactly where you land.
How to Calculate Your Capital Gain (Step by Step)
Calculating a capital gain is a three-part exercise: work out the sale price, subtract the cost base, and then apply any discounts or exemptions you’re entitled to. The ATO calls the sale price the “capital proceeds”, and the cost base is essentially what you paid to acquire, hold, and improve the asset. Let’s walk through it.
The Cost Base
The cost base includes:
-
The purchase price (what you paid for the asset).
-
Incidental costs of buying and selling: stamp duty, legal fees, agent’s commission, advertising.
-
Costs of owning the asset that you haven’t already claimed as a tax deduction — such as interest on the loan if the asset was an investment property (but only if you didn’t claim the interest as a deduction), and rates and insurance.
-
Improvement costs: a new kitchen in an investment property, for example.
-
Capital expenditure to preserve or defend your title.
You subtract the cost base from the capital proceeds to get your gross capital gain. If you sold for less than the cost base, you’ve made a capital loss, which can offset other capital gains (but not other income) and can be carried forward indefinitely.
The CGT Discount and Indexation
If you’re an Australian resident individual or trust and you’ve held the asset for more than 12 months, you can generally reduce your capital gain by 50%. That’s the “CGT discount”. For superannuation funds, the discount is 33.3%. Companies don’t get the discount. You must satisfy the 12-month holding period (the contract date, not settlement date, for real estate). Once you apply the discount, the remaining 50% is added to your income and taxed at your marginal rate.
For assets acquired before 21 September 1999, you can choose indexation instead of the discount, which adjusts the cost base for inflation up to that date. In practice, the discount usually beats indexation unless inflation was exceptionally high during your holding period. Here’s a quick comparison to show the power of the discount.
| Scenario | Gross Capital Gain | Discount Applied | Taxable Gain | Tax Payable (marginal 37% + Medicare) | Effective Tax Rate |
|---|---|---|---|---|---|
| Held <12 months (no discount) | $100,000 | No | $100,000 | $39,000 | 39% |
| Held >12 months (50% discount) | $100,000 | Yes | $50,000 | $19,500 | 19.5% |
Assumes taxpayer is in the 37% bracket (plus 2% Medicare levy), sale of an asset other than a main residence. Tax payable is illustrative only.
That 50% discount effectively halves the tax on your gain. It’s one of the reasons holding an investment property for at least a year is so common.

Major CGT Exemptions and Concessions Australians Should Know
The ATO isn’t heartless — there are important exemptions that can eliminate or reduce your CGT liability. The most famous is the main residence exemption, but there are others worth knowing about.
The Main Residence Exemption
If the property you sell is your principal place of residence — your main home — and you haven’t used it to produce income (like renting part of it out), the full capital gain is usually exempt. This exemption also covers up to six years of absence if you move out and rent the home, provided you don’t treat another property as your main residence for tax purposes during that time. The “six-year rule” is a valuable planning tool for people who relocate for work or travel but might want to sell later without CGT.
There are limits. If you rented out a portion of the home (for example, a granny flat or a room on Airbnb), a partial exemption applies, and you’ll pay CGT on a percentage of the gain. Also, if you acquired the property and used it solely as a rental, you can’t claim the exemption for the period it wasn’t your home. The ATO’s data-matching of property records and rental bonds means it’s quite good at spotting incorrect main residence claims, so get this one right.
Other Exemptions and Concessions
-
Personal use assets acquired for $10,000 or less are exempt. That means that vintage guitar you bought for $5,000 and sold for $12,000 — the gain is disregarded.
-
Collectibles acquired for $500 or less are also exempt.
-
Small business CGT concessions can wipe out all or part of a capital gain on business assets, including goodwill, if you meet the turnover test (under $2 million) or the net asset test (under $6 million). There are four separate concessions, including the 15-year exemption for older businesses, that can be stacked — I won’t unpack them all here, but they’re worth investigating if you’re selling a small business.
-
Roll-over relief lets you defer a capital gain if you replace a business asset with a new one, or if an asset is transferred due to relationship breakdown or deceased estate.
If you’re planning to lodge your own return, our lodge your own tax return Australia guide walks you through how to report these exemptions in myTax. The system will ask you about capital gains; if the gain is fully exempt under the main residence rule, you simply don’t include it.
Capital Gains Tax on Shares, Property, and Other Assets in 2026
Not all assets are treated identically, and knowing the nuances can save you money. Here’s a rundown of the key differences across the most common types.
Shares and Managed Funds
When you sell shares, the capital gain is the difference between the sale price (less brokerage) and the purchase price (plus brokerage). If you bought shares in multiple batches at different prices, you need to decide which ones you’re selling — you can’t just average the cost base unless you’re using a specific method like first-in-first-out. The 12-month discount applies if you held the shares for more than a year. Dividends are separate income and don’t affect the capital gain calculation.
Investment Property
For real estate, the contract date (not settlement) determines the CGT event date. Deductions like depreciation claimed over the years can reduce the cost base, increasing the capital gain. That’s because you’ve already received a tax benefit from those deductions. If you sold a property and had previously claimed $20,000 in capital works deductions, that amount is effectively added back as part of the gain. It’s a trap for newer investors, so keep good records.
Crypto and Collectibles
Cryptocurrency is treated as a CGT asset, and every trade (including swapping one crypto for another) triggers a potential CGT event. The discount applies if held for more than 12 months. Personal use crypto (like buying something with Bitcoin for $10,000 or less) may be exempt, but the ATO closely watches this space. Collectibles — art, jewellery, antiques — have special rules: capital losses from collectibles can only offset capital gains from other collectibles, not from shares or property.
Here’s a quick-reference table comparing CGT treatment across asset types in 2026.
| Asset Type | CGT Discount (if held >12m) | Key Exemptions | Special Rule |
|---|---|---|---|
| Australian shares | 50% for individuals | None beyond general rules | Must track cost base across multiple buys |
| Investment property | 50% for individuals | Main residence exemption if eligible | Depreciation claimed increases gain |
| Crypto | 50% for individuals | Personal use asset exemption under $10k | Every trade is potentially taxable |
| Collectibles (art, jewellery) | 50% if acquired >$500 | Exempt if acquired ≤$500 | Losses can only offset gains from other collectibles |
All rules apply for the 2025–26 financial year. Always check the ATO website for updates.
For a quick estimate of what you’ll owe after selling any of these, NeonPlay’s free Tax Calculator lets you input a capital gain and see the tax impact alongside your regular income. It’s especially helpful if you’re unsure whether the discount has been applied correctly.
5 Practical Tips for Australians to Minimise Capital Gains Tax
-
Hold assets for at least 12 months and one day to get the 50% CGT discount. The difference between selling at 11 months versus 13 months can be thousands in extra tax. If you’re close to the year mark, wait it out unless the market is crashing.
-
Time the sale for a low-income year. Because the gain is taxed at your marginal rate, if you’re taking a career break, on parental leave, or retiring, pushing the sale into a year where your other income is lower can mean a smaller slice going to the ATO.
-
Use capital losses strategically. If you have a dud stock that’s lost value, selling it in the same financial year as a large gain can offset the gain dollar for dollar. You can’t choose to not apply a loss — if you have one, it must be used — so plan the timing.
-
Keep every receipt for improvements and incidental costs. Even the stamp duty on the purchase, the conveyancer’s fee on the sale, and the cost of advertising for a tenant can all be added to the cost base. Those receipts directly reduce your capital gain, so don’t toss them.
-
Consider contributing to super to offset the tax bite. If you’ve made a big gain, making a concessional contribution (like salary sacrifice or a personal deductible contribution) can reduce your taxable income. The gain still pushes you up, but the super contribution can pull it back down, and the money goes into your retirement. Our salary sacrifice super Australia guide details the caps and setup.
Common Mistakes Australians Make With Capital Gains Tax
Mistake 1: Forgetting that the main residence exemption doesn’t apply if they rented the house out first.
If you bought a property purely as a rental and then moved in later, you’ll pay CGT for the period it was an investment. The exemption only covers the time it was genuinely your home. Many sellers are caught off guard by the partial exemption calculation.
Mistake 2: Not realising that depreciation boosts the capital gain.
When you claim depreciation on an investment property, you reduce the cost base. That means a larger capital gain when you sell. It’s not a trap, but it’s a deferral — you got deductions earlier, and you pay some back via CGT. Keep depreciation schedules in your records.
Mistake 3: Assuming they don’t need to report a gain because it’s “only a few thousand dollars.”
The ATO receives data from share registries, platforms, and state revenue offices. Even a small unreported gain can trigger a please-explain letter. When you lodge your own return, it’s far less painful to include it correctly the first time.
Mistake 4: Forgetting to apply the CGT discount if they held the asset for more than a year.
The myTax system does not automatically apply the 50% discount — you must select it. I’ve seen people pay double the tax they needed to because they skipped this box. Always double-check the holding period.
Conclusion
Capital Gains Tax in Australia 2026 doesn’t have to be a mystery. It’s simply the tax you pay on profit from selling an asset, added to your regular income and charged at your usual marginal rate. The two biggest tools at your disposal are the 50% CGT discount for assets held longer than a year and the main residence exemption for your home. Master those, keep solid records, and time your sales thoughtfully, and you can keep more of your profit where it belongs.
Right now, the smartest move is to open NeonPlay’s free Tax Calculator and plug in a hypothetical capital gain. You’ll immediately see the dollar impact, with or without the discount, and that clarity will guide your next step. If you’re about to lodge, our lodge your own tax return Australia guide will show you exactly where to report the gain. Play smart with your money — and don’t let CGT surprise you.
FAQ
What is the capital gains tax rate in Australia for 2026?
There is no separate CGT rate. Capital gains are added to your assessable income and taxed at your marginal income tax rate, which ranges from 0% to 45% plus the Medicare levy. If you held the asset for more than 12 months, you may be eligible for the 50% discount, halving the taxable gain.
How do I calculate capital gains tax on an investment property in Australia?
Subtract the cost base (purchase price plus stamp duty, legal fees, improvements, and certain holding costs) from the sale price. If you owned it for over 12 months, apply the 50% discount if eligible. Add the discounted gain to your income and calculate tax at your marginal rate.
Is my home exempt from capital gains tax?
Generally yes, if it’s your main residence and you haven’t used it to generate income. The exemption can also cover up to six years of absence if you move out and don’t claim another property as your main residence. Partial exemptions apply if you rented out part of the home.
Do I pay capital gains tax on shares in Australia?
Yes, if you make a profit when you sell. The capital gain is the difference between sale proceeds (less brokerage) and the purchase cost (plus brokerage). If held for more than 12 months, the 50% discount applies. Dividends are taxed separately as income.
Can I offset capital gains with capital losses?
Yes, capital losses must be offset against capital gains before applying the CGT discount. If your losses exceed gains, you can carry the net loss forward to future years but cannot deduct it against other income like salary. Losses from collectibles can only offset gains from collectibles.
