Calculate your CGT liability based on your asset type, holding period, and taxable income.

What is Capital Gains Tax (CGT) in Australia?

Capital Gains Tax (CGT) is the tax you pay on the profit made from the sale of an asset that has increased in value since you acquired it. In Australia, CGT is not a separate tax but forms part of your income tax. When you sell an asset for more than you paid for it, the difference (your capital gain) is added to your assessable income and taxed at your marginal tax rate.

Key points about Australian CGT:

• Applies to assets acquired after 20 September 1985 (when CGT was introduced)
• Only applies when you sell or dispose of an asset (realised gain)
• Different rules apply for different types of assets (property, shares, crypto, etc.)
• The 50% CGT discount is available for assets held for more than 12 months
• Special concessions exist for small businesses and primary residences

How Capital Gains Tax is Calculated in Australia

The basic formula for calculating CGT is:

1. Determine your capital proceeds – This is the amount you received from selling the asset
2. Calculate your cost base – This includes:
   • Original purchase price
   • Incidental costs of acquisition (stamp duty, legal fees)
   • Incidental costs of disposal (agent commissions, advertising)
   • Costs of owning the asset (for property: interest, rates, insurance)
   • Capital improvements (renovations, upgrades)
3. Compute the capital gain – Capital Proceeds minus Cost Base
4. Apply any discounts or concessions – Most common is the 50% discount for assets held >12 months
5. Add the net capital gain to your taxable income – This determines your marginal tax rate
6. Calculate the tax payable – Based on your total taxable income including the capital gain

Capital Gains Tax Rates in Australia (2023-24)

The actual CGT rate you pay depends on your total taxable income (including the capital gain) and your residency status. Here are the current Australian tax rates for residents:

Taxable Income (AUD)	Tax Rate	Tax Payable on This Tier
$0 – $18,200	0%	$0
$18,201 – $45,000	19%	19c for each $1 over $18,200
$45,001 – $120,000	32.5%	$5,092 plus 32.5c for each $1 over $45,000
$120,001 – $180,000	37%	$29,467 plus 37c for each $1 over $120,000
$180,001 and over	45%	$51,667 plus 45c for each $1 over $180,000

For non-residents, the CGT rates are different and generally higher, with no access to the 50% discount for most assets acquired after 8 May 2012.

CGT Discounts and Concessions

1. The 50% CGT Discount

The most common concession is the 50% discount for individuals and trusts (33.33% for super funds) when you’ve held the asset for more than 12 months. This effectively halves the capital gain that’s added to your taxable income.

Example: If you make a $100,000 capital gain on shares held for 18 months, only $50,000 would be added to your taxable income.

2. Small Business Concessions

If you’re a small business owner, you may be eligible for additional concessions:

• 15-year exemption – No CGT if you’ve owned the asset for 15 years and are retiring or permanently disabled
• 50% active asset reduction – Additional 50% reduction on top of the general discount
• Retirement exemption – Up to $500,000 lifetime limit (no CGT if proceeds are contributed to super)
• Rollover – Defer the gain if you reinvest in another active asset

3. Main Residence Exemption

Your family home (main residence) is generally exempt from CGT, provided:

• The property has been your main residence for the entire ownership period
• You haven’t used it to produce assessable income (e.g., renting it out)
• The land is 2 hectares or less

Partial exemptions may apply if you’ve used part of your home for business or rented it out for part of the ownership period.

Capital Gains Tax on Different Asset Types

1. Property (Investment and Rental)

For investment properties, CGT applies to the difference between the sale price and your cost base (purchase price + costs). Key considerations:

• You can claim deductions for property-related expenses while you own it
• The 50% discount applies if held for more than 12 months
• Special rules apply if you’ve lived in the property (main residence exemption)
• Capital improvements (renovations) can be added to your cost base

2. Shares and Managed Funds

CGT applies when you sell shares or units in managed funds. Special rules include:

• The 50% discount applies if held for more than 12 months
• Dividend reinvestment plans may create multiple acquisition dates
• Capital losses can be offset against capital gains
• Special rules for employee share schemes

3. Cryptocurrency

The ATO treats cryptocurrency as a CGT asset. Key points:

• Every crypto-to-crypto trade is a CGT event
• Using crypto to purchase goods/services is a disposal
• The 50% discount applies if held for more than 12 months
• Record-keeping is critical (dates, values in AUD, transaction purposes)

4. Collectibles and Personal Use Assets

Special rules apply to collectibles (art, jewelry, antiques) and personal use assets (boats, cars):

• Capital gains on collectibles are only taxed if the gain exceeds $500
• Personal use assets acquired for less than $10,000 are generally exempt
• Different cost base rules may apply

How to Minimise Capital Gains Tax in Australia

While you can’t avoid CGT entirely (unless you qualify for an exemption), there are legitimate strategies to minimise your liability:

1. Hold assets for more than 12 months – To qualify for the 50% discount
2. Use the timing of sales – Sell in a year when your income is lower to reduce your marginal rate
3. Offset capital losses – Use capital losses to reduce your capital gains
4. Contribute to super – Some small business concessions allow tax-free contributions
5. Consider partial exemptions – For properties that were your main residence for part of the ownership
6. Structure your investments – Holding assets in a company or trust may provide tax advantages
7. Keep excellent records – To maximise your cost base and claim all eligible deductions
8. Use the small business concessions – If you qualify, these can significantly reduce or eliminate CGT

Common Capital Gains Tax Mistakes to Avoid

Many taxpayers make errors when dealing with CGT that can lead to overpaying tax or ATO scrutiny:

• Not keeping proper records – Without receipts and documentation, you may miss eligible cost base additions
• Forgetting about the 12-month rule – Selling just before the 12-month threshold means losing the 50% discount
• Incorrectly calculating the cost base – Missing incidental costs or improvements
• Not considering partial exemptions – For properties that were both investment and main residence
• Ignoring capital losses – Not using losses to offset gains in the same or future years
• Assuming all assets are exempt – Many taxpayers incorrectly assume their asset is exempt from CGT
• Not reporting crypto transactions – The ATO has sophisticated data matching for cryptocurrency
• Incorrectly applying small business concessions – These have strict eligibility requirements

Capital Gains Tax for Non-Residents

Non-residents are subject to different CGT rules in Australia:

• No 50% discount – For most assets acquired after 8 May 2012
• Different tax rates – Generally taxed at 32.5% or 45% depending on the gain amount
• Main residence exemption – Only available if you were a resident for at least part of the ownership period
• Withholding rules – 12.5% of the sale price may be withheld for properties over $750,000

Non-residents should seek professional advice as the rules are complex and penalties for non-compliance can be severe.

Capital Gains Tax vs. Income Tax

It’s important to understand how CGT differs from regular income tax:

Feature	Capital Gains Tax	Income Tax
When it applies	Only when you sell/dispose of an asset	On regular income (salary, wages, business income)
Tax rate	Your marginal rate (but 50% discount often applies)	Your marginal rate (no discount)
Timing	One-off event when asset is sold	Ongoing on income as it’s earned
Deductions	Cost base reductions (purchase price, expenses)	Work-related and other deductions
Losses	Can be carried forward to offset future gains	Generally can’t be carried forward (except business losses)
Exemptions	Main residence, small business concessions	Tax-free threshold ($18,200)

Recent Changes to Capital Gains Tax in Australia

The Australian government regularly reviews and updates CGT rules. Recent and upcoming changes include:

• Foreign resident CGT withholding – Increased from 10% to 12.5% for properties over $750,000 (from 1 July 2017)
• Main residence exemption for non-residents – Removed for properties acquired after 9 May 2017
• Cryptocurrency reporting – Increased ATO scrutiny and data matching with exchanges
• Small business concessions – Tightened eligibility rules to prevent misuse
• Collectibles threshold – Increased from $500 to $10,000 for personal use assets

Always check the ATO website for the most current information.

Frequently Asked Questions About CGT in Australia

Do I pay CGT if I inherit property?

Generally no CGT when you inherit property, but you may pay CGT when you eventually sell it. The cost base is usually the market value at the date of death.

What if I sell an asset for less than I paid?

This creates a capital loss, which can be used to offset capital gains (but not other income). Unused losses can be carried forward to future years.

How does CGT work with divorce or separation?

Asset transfers between spouses due to divorce are generally CGT-free, but the receiving spouse takes on the original cost base.

Do I pay CGT on my primary residence?

Generally no, provided it was your main residence for the entire ownership period and the land is 2 hectares or less.

How do I report CGT on my tax return?

You need to complete the Capital Gains section of your tax return (Item 18 for individuals). The ATO provides worksheets to help with calculations.

What records do I need to keep for CGT?

You should keep records of:

• Purchase and sale contracts
• Receipts for purchase costs and improvements
• Records of incidental costs (legal fees, agent commissions)
• Dates of acquisition and disposal
• Market valuations if needed

You must keep these records for 5 years after the CGT event (longer in some cases).
