From Purchase to Sale: How This Calculator Works

Our Capital Gains Tax Calculator reflects the way the ATO actually taxes a gain. Start by selecting the relevant financial year, so the right rates apply. Then enter your cost base (purchase price plus buying, selling, and improvement costs) and your sale price. Tell us whether you’ve held the asset for more than 12 months, as this determines if the 50% CGT discount applies. Then select your entity type; individual, trust, or company, since each is taxed differently.

Add any other taxable income so we can apply the correct marginal rate. In seconds, you’ll get a full breakdown: your capital gain, the discount applied, your taxable gain, the applicable rate, and your estimated CGT payable.

AAD Taxation got me a refund I never knew I was entitled to. Professional, quick, and explained everything in plain English. They found deductions my previous accountant completely missed. Absolutely outstanding!

Priya S.

As a small business owner, BAS and payroll was a nightmare. AAD took everything off my plate and the fixed pricing means no surprises. Their team responds within hours — incredible service, highly recommended.

Raj M.

I had 3 overdue tax returns and was terrified of the ATO. AAD sorted everything, negotiated my penalties down, and set up a payment plan. Now I’m fully up to date. They literally saved me thousands!

FAQs

Got Questions? We've Got Answers

Straight answers to the capital gains tax questions Australians ask most.

What is capital gains tax in Australia?

Capital gains tax isn’t a separate tax; it’s the tax you pay on the profit made when you sell an asset, added to your income for that financial year.

How is capital gains tax calculated?

Your capital gain is the sale price minus the original purchase price and eligible costs, like legal fees or improvements. If you’ve held the asset for more than 12 months, you may only need to include half of that gain in your taxable income.

Do I have to pay CGT on my home?

Your main residence is usually exempt from CGT, but there are times when it might not be if you’ve used part of it to make money or moved out and rented it out before selling.

What is the 50% CGT discount?

If you’re an individual and you’ve owned the asset for more than 12 months, you can reduce your taxable capital gain by 50% before it’s added to your income.

Do I pay CGT when I sell shares?

Yes. Shares are treated as CGT assets, so any profit made on selling them is generally subject to capital gains tax, unless an exemption applies.

Can I offset a capital loss against a capital gain?

Yes. Capital losses can reduce capital gains in the same year, and any unused losses can be carried forward to offset gains in future years.

Do I need to report a capital gain even if I don’t sell everything?

Yes. Capital gains tax (CGT) is charged when you sell or give away an asset, even if you only give it away in part. This means that you have to report any capital gains.

Does a company pay CGT the same way as an individual?

Not at all. People don’t get the 50% CGT discount, and the gain is taxed at the company tax rate instead of the marginal rate for an individual. This means the same sale can result in a very different tax outcome depending on the entity that owns the asset.
