Calculate your capital gains tax liability based on ATO rules for 2024-25

Capital Gains Tax (CGT) is a critical consideration for Australian taxpayers when disposing of assets. This guide explains how CGT works under the Australian Taxation Office (ATO) rules, how to calculate your liability, and strategies to legally minimise your tax obligation.

What is Capital Gains Tax?

Capital Gains Tax is the tax you pay on the profit (capital gain) made from the sale of an asset. Unlike income tax which applies to your earnings, CGT applies to the increase in value of your assets from the time you acquire them until you dispose of them.

Key points about CGT:

• It’s not a separate tax – it’s part of your income tax
• You only pay tax on the net capital gain (after applying discounts and offsets)
• Not all assets are subject to CGT (your home may be exempt under the main residence exemption)
• The tax is calculated based on your marginal tax rate

Which Assets Are Subject to CGT?

The ATO considers most assets you’ve acquired since 20 September 1985 (when CGT was introduced) as subject to CGT. Common examples include:

Asset Type	CGT Applies?	Special Considerations
Investment properties	Yes	May qualify for 50% discount if held >12 months
Shares and ETFs	Yes	Dividends may also have tax implications
Cryptocurrency	Yes	ATO treats crypto as property, not currency
Collectibles (art, jewellery)	Yes (if acquired for >$500)	Special rules for collectibles held >12 months
Business assets	Yes	Small business concessions may apply
Personal use assets (car, boat)	Only if cost >$10,000	Special exemption for personal items
Main residence (family home)	Generally No	Full exemption usually applies

How to Calculate Your Capital Gain

The basic formula for calculating your capital gain is:

Capital Gain = Capital Proceeds – Cost Base

1. Capital Proceeds

This is what you receive from the sale of the asset. It includes:

• The sale price of the asset
• Any compensation you receive for the asset
• The market value if you give the asset away

2. Cost Base

This is the total cost of acquiring, holding, and disposing of the asset. It typically includes:

• The original purchase price
• Incidental costs of acquisition (legal fees, stamp duty)
• Costs of ownership (interest on loans to acquire the asset isn’t included)
• Capital improvements (renovations that increase value)
• Incidental costs of disposal (agent’s commission, advertising)

3. Net Capital Gain

After calculating your capital gain, you may be able to:

• Apply the 50% CGT discount (if you’ve held the asset for more than 12 months)
• Apply any capital losses from other assets
• Use small business concessions if eligible

Capital Gains Tax Discounts

The most significant CGT discount is the 50% discount for individuals and trusts (33.33% for super funds) when you’ve held an asset for more than 12 months.

Entity Type	Discount Percentage	Minimum Holding Period
Individuals	50%	12 months
Trusts	50%	12 months
Self-Managed Super Funds	33.33%	12 months
Companies	0%	N/A
Non-residents	0%	N/A (since 8 May 2012)

Important note: The 50% discount was removed for non-residents for CGT events happening on or after 8 May 2012, except for certain temporary residents.

Capital Gains Tax Rates 2024-25

CGT isn’t a separate tax – it’s added to your assessable income and taxed at your marginal tax rate. Here are the current tax rates for Australian residents (2024-25):

Taxable Income Threshold	Tax Rate	Plus
$0 – $18,200	0%	Nil
$18,201 – $45,000	19%	Nil
$45,001 – $120,000	32.5%	$5,092
$120,001 – $180,000	37%	$29,467
$180,001 and over	45%	$51,667

For non-residents, the tax rates are different:

• 0% on income up to $120,000
• 32.5% on income $120,001-$180,000
• 37% on income $180,001-$250,000
• 45% on income over $250,000

Special Cases and Exemptions

1. Main Residence Exemption

Your family home (main residence) is generally exempt from CGT when you sell it. However, there are important conditions:

• The property must have been your main residence for the entire ownership period
• You can’t claim the exemption for more than one property at a time (with some exceptions)
• The land size must be 2 hectares or less (there are some exceptions)
• You can’t have used the property to produce assessable income (e.g., as a rental)

If you’ve used part of your home to produce income (e.g., running a business from home), you may need to apportion the capital gain.

2. Small Business Concessions

If you’re a small business owner, you may be eligible for one or more of these concessions:

1. 15-year exemption: If you’ve owned the asset for 15 years and are retiring or over 55
2. 50% active asset reduction: Reduces the capital gain by 50% (on top of the general 50% discount)
3. Retirement exemption: Up to $500,000 lifetime limit (no CGT on this amount)
4. Rollover: Defer the capital gain if you buy a replacement asset

To qualify, your business must have aggregated turnover of less than $2 million or net assets of less than $6 million.

3. Inherited Assets

When you inherit an asset, you’re generally taken to have acquired it at its market value at the date of death (for assets acquired before 20 September 1985) or at the deceased’s cost base (for assets acquired after that date).

The 12-month ownership period for the CGT discount includes the period the deceased owned the asset.

How to Reduce Your Capital Gains Tax

There are several legitimate strategies to minimise your CGT liability:

1. Hold assets for more than 12 months: This makes you eligible for the 50% discount
2. Use capital losses: Offset capital gains with any capital losses you’ve incurred
3. Time the sale: If possible, sell in a year when your income is lower to reduce your marginal tax rate
4. Contribute to super: If eligible, you might contribute some of the sale proceeds to superannuation
5. Use the small business concessions: If you qualify, these can significantly reduce or eliminate CGT
6. Consider partial exemptions: For assets used partly for income-producing purposes
7. Use the temporary absence rule: For your main residence if you move out temporarily

Common Mistakes to Avoid

Many taxpayers make errors when dealing with CGT. Here are some common pitfalls:

• Not keeping proper records: You need to keep records of acquisition and disposal for 5 years after the CGT event
• Forgetting to include all costs: Many people only consider the purchase price and forget incidental costs
• Incorrectly calculating the 12-month period: The discount applies if you’ve owned the asset for more than 12 months, not from settlement to settlement
• Not considering partial exemptions: For assets used partly for income and partly private purposes
• Assuming all property sales are tax-free: Only your main residence is generally exempt
• Not reporting crypto transactions: The ATO has sophisticated data-matching for cryptocurrency
• Ignoring foreign assets: Australian residents must pay CGT on worldwide assets

Record Keeping Requirements

The ATO requires you to keep records that relate to acquiring, holding, and disposing of assets for CGT purposes. You must keep these records for:

• 5 years after the CGT event (for most assets)
• As long as you own the asset + 5 years (for assets you still own)

Records you should keep include:

• Receipts of purchase and sale
• Contract of sale
• Receipts for incidental costs (legal fees, stamp duty)
• Receipts for capital improvements
• Market valuations (if relevant)
• Records of how you calculated your capital gain or loss

How the ATO Tracks Capital Gains

The ATO has sophisticated data-matching systems to identify capital gains that should be reported. They receive information from:

• Share registries for share transactions
• Property title offices for real estate sales
• Cryptocurrency exchanges
• Banks and financial institutions
• Foreign tax authorities (through international agreements)

If you don’t report capital gains when you should, you may face:

• Penalties and interest charges
• Audits and more detailed scrutiny of your tax affairs
• Potential criminal charges for serious cases of tax evasion

Recent Changes to CGT Rules

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

1. Foreign resident CGT rules: Since 2017, foreign residents are subject to CGT on Australian property regardless of when it was acquired
2. Main residence exemption for non-residents: Since 2020, non-residents can no longer claim the main residence exemption
3. Vacant land changes: Tighter rules on claiming the main residence exemption for vacant land
4. Cryptocurrency reporting: Increased ATO focus on crypto transactions with data-matching programs
5. Small business concessions: Some changes to eligibility rules for small business CGT concessions

Frequently Asked Questions

Do I pay CGT if I sell my home?

Generally no, if it’s been your main residence for the entire time you’ve owned it. However, if you’ve rented it out or used part of it for business, you may need to pay CGT on a portion of the gain.

How is CGT calculated for shares?

The calculation is the same as for other assets: sale proceeds minus cost base. For shares, your cost base includes the purchase price plus brokerage fees. If you’ve received dividends through a dividend reinvestment plan, these increase your cost base.

What if I make a capital loss?

Capital losses can be used to offset capital gains in the same year or carried forward to offset future capital gains. You can’t offset capital losses against other income.

Do I pay CGT if I give an asset away?

Yes, the ATO considers giving away an asset as a disposal for CGT purposes. The market value at the time of the gift is considered your capital proceeds.

How does CGT work for inherited property?

When you inherit property, you’re generally taken to have acquired it at its market value at the date of death. If you later sell it, you’ll pay CGT on the difference between the sale price and this market value.

Can I avoid CGT by reinvesting the proceeds?

Generally no, unless you qualify for the small business rollover concession. For most assets, you’ll need to pay CGT when you sell, regardless of what you do with the proceeds.

When to Seek Professional Advice

While this calculator provides a good estimate, CGT can be complex. You should consider seeking professional advice from a tax accountant or financial advisor if:

• You’re dealing with large capital gains (over $100,000)
• You have complex ownership structures (trusts, companies)
• You’re a non-resident or your residency status has changed
• You’re selling a business or business assets
• You’ve inherited assets with complex ownership history
• You’re dealing with international assets
• You’re unsure about any aspect of your CGT obligations
