Plus, we’ll share expert tips to legally reduce your CGT bill. Let’s dive in!
What Is Capital Gains Tax (CGT)?
Think of Capital Gains Tax (CGT) as the ATO’s way of sharing in your success, whenever you sell an asset for more than you paid for it, they want a slice of the profit. That profit, aka your capital gain, gets added to your taxable income for the year and is taxed at your marginal tax rate.
How Does Capital Gains Tax Work?
Unlike a flat tax, where everyone pays the same percentage, CGT scales with your earnings. The more you make, the more you pay. But don’t worry, there are ways to reduce CGT, and we’ll cover those soon!
📌 Quick Example:
- You buy shares for $10,000 and sell them for $15,000.
- That $5,000 profit (capital gain) is added to your taxable income.
- If you’ve held the shares for over 12 months, you may be eligible for the 50% CGT discount (meaning only $2,500 is taxed).
Bottom line? CGT isn’t a separate tax—it’s just part of your overall taxable income.
What Assets Are Subject to CGT?
Not everything you sell will attract CGT. The ATO doesn’t care if you offload your old couch or finally say goodbye to that second-hand car from 2005. But if you’re cashing in on the following, CGT applies:
📌 Assets that attract CGT:
- ✅ Investment properties – If it’s not your main home, it’s fair game for CGT.
- ✅ Shares & ETFs – Whether you’re a long-term investor or a frequent trader, capital gains (or losses) apply.
- ✅ Cryptocurrency – Buying and holding crypto? No problem. But the moment you sell, swap, or even use it to buy something, CGT is triggered.
- ✅ Business assets – Selling a business or business property? You’ll likely face CGT, though small business concessions may apply.
- ✅ Collectibles over $500 – Art, rare coins, vintage cars—if they appreciate in value and you sell them, the taxman wants in.
📌 Assets that are CGT-exempt:
- 🚫 Your main residence (as long as you’ve lived in it the whole time). We’ll explain this one in more detail below.
- 🚫 Personal-use assets under $10,000 (e.g., your car, furniture, or that giant flat-screen TV).
- 🚫 Depreciating business assets (like computers and machinery).
CGT Exemptions and Discounts
The ATO isn’t completely heartless—there are several CGT exemptions and discounts to soften the blow:
- 50% CGT Discount – If you’ve held the asset for more than 12 months, individuals and trusts can slash their taxable gain by 50%. (Sorry, companies, you miss out on this one.)
- Main Residence Exemption – If the property you’re selling has been your primary home since day one, you won’t pay a cent in CGT. However, if you’ve rented it out or used it for business, you might only get a partial exemption.
- The Six-Year Rule (Even After Moving Out or Divorce) – If you move out of your main home and rent it out, you can still claim the main residence exemption for up to six years, as long as you don’t buy another “primary residence”.
- Relationship breakdown? If a property is transferred between spouses due to divorce or separation, CGT is usually deferred until the receiving party sells it meaning no immediate tax hit. However, if they later sell, the CGT calculation will consider the original purchase date and price, not the date of transfer.
- Small Business CGT Concessions – Own a small business? You might qualify for some serious tax breaks, including a 15-year CGT exemption or the ability to roll over your CGT liability into another investment.
✅ Pro tip: The best way to legally reduce CGT is through strategic timing and tax planning, which is why an automated capital gains tax calculator is a game-changer.

Calculating CGT manually is about as fun as doing your own dental work. Every sale requires you to track costs, sale prices, holding periods, deductions, and offsets—and get one figure wrong? The ATO won’t be amused.

Tips to Reduce Your Capital Gains Tax
No one likes handing over more tax than necessary. Here are proven strategies to minimize your CGT bill:
1. Hold Assets for 12+ Months
Selling too soon? You’ll miss out on the 50% CGT discount. If possible, hold onto assets for at least a year to halve your tax bill.
2. Offset Gains with Losses
If you’ve had a bad investment year, don’t despair—use capital losses to offset capital gains and reduce your tax liability.
3. Time Your Sale in a Low-Income Year
CGT is added to your taxable income, so if you’re expecting a lower-income year (e.g., career break, maternity leave, or retirement), selling then could push you into a lower tax bracket.
4. Contribute to Superannuation
Did you know you can use super contributions to offset CGT? If you’re under the concessional cap ($27,500 per year), making a pre-tax contribution can reduce your taxable income and lower your CGT bill.
5. Use the Bring-Forward Rule
Did you know you can carry forward unused concessional super contributions for up to five years if you’ve contributed less than the annual caps? This allows you to make a larger tax-deductible contribution, reducing both your taxable income and CGT liability, as long as your super balance is under $500,000.
6. Automate CGT Calculations with TaxTank
Tracking CGT across property, shares, crypto, and business assets can be overwhelming. TaxTank automates everything, cost base tracking, loss offsets, and CGT discounts, ensuring you never overpay. It also applies grandfathering provisions, securely stores all records, and generates ATO-compliant reports, saving you time, stress, and tax dollars.
