Have you ever sold something for a tidy profit, only to later realise the taxman wants a cut? It’s a nasty surprise. You thought you’d come out ahead, but suddenly there’s this thing called Capital Gains Tax (CGT) staring you down.
And it’s not a separate tax with its own rate. It’s part of your income tax. Which means, if you’re not careful, a decent chunk of your gain can vanish straight into the ATO’s pocket.
If that sounds like something you’d rather avoid, keep reading. This could save you from making a very expensive mistake.
What exactly is a capital gain?
Put simply, a capital gain is the profit you make when you sell an asset for more than you paid for it. It could be shares, an investment property, cryptocurrency, a managed fund, or even collectables like coins and art.
Say you bought some shares for $5,000 and sold them for $9,000. That $4,000 profit is a capital gain. On the flip side, if you sold them for $3,000, you’ve made a capital loss. Losses aren’t a total waste, though — they can be used to reduce future gains.
There’s no separate CGT rate in Australia
Here’s where people get caught out. Australia doesn’t have a special CGT tax rate. Your net capital gain is added to your regular income and taxed at your marginal rate. So if you’re already in a higher income bracket, your gain could be taxed at 37% or even 45%.
Think about that for a second. You might have planned to use that profit for a holiday or an upgrade to the family car. Instead, a big slice of it could end up going to the ATO.
What’s covered and what’s not
CGT applies to:
- Shares and units in trusts
- Investment properties
- Cryptocurrencies
- Managed funds
- Collectables (over $500 for certain items)
- Personal use assets worth more than $10,000, like boats or caravans
CGT doesn’t apply to:
- Your main residence (with some exceptions if you’ve rented it out or used it for business)
- Cars and motorbikes
- Depreciating business assets such as laptops, tools, or machinery
If you’re unsure whether something is covered, don’t guess. The ATO uses data-matching from share registries, property sales, and crypto platforms. If you’ve sold it, chances are they already know.
How to work out your gain or loss
- Figure out your cost base: this is what you paid for the asset, plus buying costs like stamp duty, legal fees, agent commissions, and improvement expenses.
- Work out your capital proceeds: what you got when you sold it, or its market value if you gave it away.
- Subtract the cost base from the proceeds: if it’s positive, that’s your gain. If it’s negative, that’s your loss.
Sounds simple, but get it wrong and you might pay more tax than you should.
The 50% CGT discount
If you’re an individual and you’ve held the asset for at least 12 months before selling, you could be eligible for a 50% discount on the gain. That means only half the gain gets added to your taxable income.
Here’s the difference it can make:
- Sell shares with a $20,000 gain after 12 months — only $10,000 is taxable.
- Sell them in less than 12 months — the full $20,000 is taxable.
Timing matters. Selling too early could cost you thousands.
Using capital losses
Capital losses can only be used to reduce capital gains. You can’t use them to lower your salary or business income. But if your losses are bigger than your gains, you can carry them forward to offset gains in future years.
This is where good record-keeping pays off. Without the paperwork, you could lose the chance to use those losses.
When CGT kicks in
CGT is triggered by what the ATO calls a “CGT event”. Most of the time, this is when you sell or give away the asset. The date matters because it determines which financial year you need to report it in.
If you sell in May, you report it in that year’s tax return. If you sell in July, it goes into the next one. Get the timing wrong and you could end up lodging incorrect information — and that’s not a conversation you want to have with the ATO.
Keep your records — it’s not optional
The ATO expects you to keep:
- Purchase and sale contracts
- Receipts for related costs like stamp duty and legal fees
- Records of improvements or renovations
- Any valuations used
Keep these for at least five years after you sell the asset. Without them, proving your cost base becomes tricky, and the ATO could end up using a less favourable figure.
Why this matters right now
It’s easy to think, “I’ll worry about it when I sell.” But CGT planning starts long before you sign the sale contract. The timing of a sale, whether you qualify for the discount, and how you use past losses can all change the amount you pay.
Think about two investors selling the same property for the same profit. One sells after 13 months and uses the 50% discount, saving thousands. The other sells at 11 months and pays full tax on the gain. The only difference? Timing.
Final word
If you sell something for more than you bought it, the ATO wants its share. CGT isn’t something you can ignore or hope will slip under the radar. Keep your records, know the timing rules, and take advantage of the discount where you can.
Getting this right could mean the difference between keeping that extra money in your pocket or sending it to the tax office. And if you’re unsure, get professional advice before you sell because once the sale is done, so is your chance to change the tax outcome.
