Capital Gains Tax on Property: What Australian Investors Need to Know in 2026

Capital gains tax (CGT) is one of the most significant tax obligations for Australian property investors. Whether you sell an investment property, transfer shares, or dispose of a rental property, understanding capital gains tax is essential. This guide will help you understand how CGT applies, the 50% CGT discount, cost base rules, key exemptions, 2025-26 tax rates, and effective strategies to help reduce your CGT liability.

Understanding Capital Gains Tax in Australia

What Is Capital Gains Tax (CGT)?

Capital gains tax is not a separate tax — it is part of your income tax. A capital gain or loss is triggered when you sell or dispose of a CGT asset such as property, shares, or a business. The capital gain is the difference between the sale price and cost base, added to your assessable income and taxed at your marginal tax rate. The ATO introduced capital gains tax on 20 September 1985, meaning assets acquired before that date are generally exempt.

When Does Capital Gains Tax Apply?

A CGT event is triggered in several circumstances, and the rules can vary depending on the type of asset:

• You sell an investment property, shares, or other assets for a profit

• You gift or transfer property to another person

• You receive compensation for loss of an asset

• You change the use of a property — for instance, moving from your main residence to a rental property

• You dispose of personal use assets worth more than $10,000 (excluding motorcycles and personal belongings)

Capital gains tax applies to Australian residents on worldwide assets and to foreign residents on taxable Australian property. Depending on your circumstances, the capital gains rules can vary. Seek information and services when making decisions about selling or disposal of assets.

What Assets Are Subject to Capital Gains Tax?

Most assets are subject to CGT, including real estate, shares, managed funds, and business assets. Key exemptions include your main residence (family home), personal use assets under $10,000, vehicles, and assets acquired before 20 September 1985.

How Capital Gains Tax Works on Property

How to Calculate Your Capital Gain or Loss

To calculate your capital gain or loss, subtract the cost base from the capital proceeds (the sale price plus any amounts you receive). If the result is negative, you have a capital loss.

Capital Gain = Sale Price - Cost Base

For example, if you sell an investment property for $850,000 with a cost base of $600,000, the capital gain is $250,000. This amount is included in your tax return and assessed at your marginal rate — unless you qualify for the 50% CGT discount or other options.

What Is Included in the Cost Base?

The cost base includes five elements used to calculate how much you paid to acquire, hold, and dispose of the asset:

1. Original cost — the purchase price paid for the property

2. Incidental costs — stamp duty, legal fees, and conveyancing costs paid at purchase

3. Ownership costs — non-deductible expenses not already claimed as deductions

4. Capital improvements — renovations, building costs, and structural improvements included over time

5. Costs of disposing — agent fees, advertising, and legal costs included in the transaction

Keeping accurate records of all amounts paid is one of the most important rules. The ATO requires records for the period you own the asset plus five years after the sale. This information can help you calculate capital gains accurately and avoid paying more tax than necessary.

The Reduced Cost Base

The reduced cost base excludes costs already claimed as deductions (such as capital works deductions). If you sell for less than the reduced cost base, you realise a net capital loss. Capital losses only offset capital gains — never ordinary income — and carry forward to future years.

The 50% CGT Discount

How the Capital Gains Concession Works

Australians who hold a CGT asset for more than 12 months before selling qualify for the 50% CGT discount — only half the capital gain is included in taxable income. For a self-managed super fund, the concession is one-third (33.33%), reducing the taxable portion. Companies are not eligible for the capital gains concession and must pay tax on the full amount.

Who Qualifies for the 50% CGT Concession?

• Individual Australian residents — assets held more than 12 months

• Trusts — the concession flows through to individual beneficiaries

• Self-managed super funds — one-third discount rate applies

Foreign residents cannot access the CGT discount on assets acquired after May 2012. Non-residents pay capital gains tax on the full amount.

Worked Example: CGT on Investment Property

An Australian resident investor purchased a property in 2019 for $500,000. In 2026, they sell for $750,000 after holding the asset for more than 12 months:

The $87,500 net capital gain is added to the investor's total for the financial year and taxed at their marginal rate. Capital losses from previous years would offset the gain first, reducing CGT paid.

Main Residence Exemption

How the Main Residence Exemption Applies

The main residence exemption is the most powerful CGT exemption for Australian property owners. If you sell your family home — the property you lived in as your main residence — the entire capital gain is exempt, provided you meet the eligibility rules:

• You lived in the property as your main residence for the entire period of ownership

• You did not use it to produce rental income

• You did not claim it as a home office or business deduction

• The land is 2 hectares or less

You can only nominate one property as your main residence at any time. Making the right choice can help you avoid capital gains entirely.

The Six-Year Rule (Absence Rule)

The six-year rule is one of the most valuable rules for investors. If you move out of your main residence — moving interstate or overseas for work — you can treat the property as your main residence for up to six years while it is rented out. The six years begins from when you first move out.

The six-year rule allows you to:

• Rent your home for up to six years and still claim the main residence exemption when you sell

• Collect rental income during the six-year period

• Reset the six-year period by moving back in before it expires, then moving out again

If you rent beyond the six years without moving back, a partial exemption applies based on the portion of time it was your main residence. Over time, this benefits Australians moving for work while keeping long-term investment options open.

Partial Main Residence Exemption

If you first used a property as your main residence then later rented it out, the capital gain is apportioned based on the number of days the property was your main residence versus the total ownership period.

CGT and Different Entity Types

Individuals

For individuals, the net capital gain is added to total taxable income at your marginal rate. The 50% CGT discount applies for assets held over 12 months.

Companies

A company pays tax on the full capital gain at the company rate (25% or 30%). Companies are not eligible for the 50% concession. Shares held in companies follow the same capital gains rules.

Trusts

A trust distributes capital gains to beneficiaries, who include them in individual tax returns. Trusts offer flexibility distributing to beneficiaries in lower brackets, which can help families manage capital gains liability.

Self-Managed Super Funds (SMSFs)

An SMSF in accumulation phase pays 15% on capital gains (10% effective with the one-third concession for assets held over 12 months). In retirement phase, capital gains are tax-free — making super attractive for long-term wealth.

2025-26 Capital Gains Tax Rates

Individual Tax Rates (2025-26 Financial Year)

Capital gains are taxed at your marginal tax rate for the financial year you sell:

Plus 2% Medicare levy. A large capital gain can push you into a higher bracket, so timing matters. The Stage 3 tax reforms introduced in 2024-25 continue to apply, providing lower rates for Australians making capital gains.

Foreign Resident Tax Rates

Foreign residents receive no tax-free threshold and pay 30% from the first dollar up to $135,000, then 37% and 45% at higher levels. If you are a non-resident selling Australian property, seek professional advice and information about your tax obligations.

Capital Losses: Reducing Your Capital Gains

Using Capital Losses to Offset Capital Gains

If you sell shares, property, or another asset for less than its reduced cost base, you realise a capital loss. Capital losses offset capital gains only — never ordinary income. Key rules to understand:

• Apply capital losses before the 50% CGT discount

• Losses from collectibles only offset capital gains from collectibles

• Wash sales (selling shares at a loss then immediately buying back) may be disallowed by the ATO

• You cannot avoid these rules by using different financial services or accounts

Carrying Forward Capital Losses to Future Years

Net capital losses carry forward indefinitely to offset capital gains in future years. This makes timing strategically important — consider selling a losing investment in the same year as a profitable property to reduce CGT paid.

Effective Strategies to Reduce Capital Gains Tax

Hold Assets for More Than 12 Months

Hold your investment property or shares for more than 12 months to qualify for the 50% CGT discount. On a capital gain of $200,000, you pay tax on only $100,000 — making this one of the most effective options.

Maximise Your Cost Base

Keep records of every expense included in the cost base — renovations, improvements, building costs, stamp duty, legal fees, and agent commissions. Making the effort to track amounts paid can help reduce capital gains substantially.

Time Your Sale Strategically

Consider selling in a financial year when your other income is lower. Since capital gains are added to taxable income, selling when income is lower means the gain falls into a lower bracket. If you are approaching retirement, this can help reduce CGT paid. Exchange contracts before or after 30 June to align with the most favourable year.

Offset Capital Gains with Capital Losses

If you hold shares or other assets that have fallen in market value, consider selling them in the same financial year as your property. This tax-loss harvesting strategy can help reduce your net capital gain. Avoid wash sales — the ATO monitors these transactions.

Use the Main Residence Exemption and Six-Year Rule

The six-year rule lets you rent your home while keeping the main residence exemption. Moving back before the six years expires resets the clock. This is one of the most effective strategies to eliminate capital gains on properties that would produce significant gains.

Contribute to Superannuation

Making additional super contributions in the year you sell reduces total taxable income, pushing the capital gain into a lower bracket. Concessional contributions are taxed at 15% inside super. Speak to a financial adviser about caps, eligibility, and other options.

Choose the Right Ownership Structure

The entity structure affects your capital gains outcome. Individuals receive the 50% CGT discount, trusts offer distribution flexibility to beneficiaries, and super funds provide concessional rates. Getting the right structure is critical for long-term gains — changing ownership triggers a CGT event.

Small Business CGT Concessions

Small business owners may qualify for generous concessions: the 15-year exemption, 50% active asset reduction, retirement exemption, and rollover relief. These concessions can substantially reduce or eliminate capital gains on business assets. Australians should seek professional services to determine eligibility.

Seek Professional Tax Advice

Capital gains rules are complex. A tax professional can help you calculate your gain, identify available options, structure your investment portfolio, and manage obligations. The ATO provides free information and services including a CGT calculator on their website for Australians.

Frequently Asked Questions About Capital Gains Tax

Do I Pay CGT on My Family Home?

Generally no. If the property was your main residence for the entire period, the main residence exemption applies and you avoid paying CGT. If you rented it out, a partial exemption may apply depending on your circumstances and the rules for your situation.

Can I Avoid Capital Gains Tax on Investment Property?

You cannot completely avoid capital gains tax unless specific exemptions apply (the six-year rule allowing up to six years of renting, or assets acquired before 20 September 1985). However, effective strategies can reduce your capital gains significantly — holding for 12 months, maximising cost base, and making strategic timing decisions.

How Do I Report Capital Gains on My Tax Return?

Capital gains and losses are declared in your tax return for the year the CGT event occurred. The ATO provides record-keeping tools and information to calculate your net capital gain or loss. A tax professional can help find options to minimise tax paid.

What Happens If I Inherit Property?

Inheriting property does not trigger a CGT event. When you later sell, capital gains tax applies. The cost base depends on when the deceased acquired the property. For assets acquired before 20 September 1985, the cost base is market value at death. Rollover relief defers CGT until the beneficiary sells.

Are Foreign Residents Treated Differently?

Yes. Foreign residents face no tax-free threshold, no 50% CGT discount (for post-May 2012 assets), withholding on property transactions over $750,000, and different rates from the first dollar. Seek expert advice and services if you are a non-resident selling Australian property.

CGT Events and Timing

CGT is triggered by a "CGT event," typically when selling, gifting, or transferring ownership of an investment property, rental property, or other CGT asset. The CGT event is dated from when you sign the contract of sale, not the settlement date. This distinction matters because the contract date determines which financial year the gain falls into and whether you qualify for the 50% CGT discount.

Holding Period Benefits

Holding property for over 12 months allows investors to benefit from market cycles, as property values tend to appreciate over time, potentially resulting in significant capital gains. Long-term ownership of property not only provides tax benefits but also allows for the accumulation of rental income, which can improve the overall return on investment.

Main Residence Exemption in Detail

To qualify for the main residence exemption, the property must have been your genuine home, meaning you and your family lived there, your personal belongings were kept there, and your mail was delivered there. Foreign residents generally cannot claim the main residence exemption unless meeting specific conditions.

If you buy a new home before selling your old one, both can be treated as your main residence for an overlap of up to six months if specific conditions are met.

The 6-Year Rule Explained

If you move out of your main residence and rent it out, you can still claim the main residence exemption for up to six years under the 6-year rule, provided you have not nominated another property as your main residence during that time. If you sell your property within the six-year exemption period, you can generally claim a full main residence exemption from capital gains tax, provided you have not nominated another property as your main residence during that time.
