Minimising Capital Gains Tax on investment property guide
.
When selling an investment property, your CGT liability affects your total taxable income for the financial year. The Australian Tax Office calculates this tax based on your net capital gains – the difference between your property’s sale price and its cost base. Understanding these calculations helps property investors minimise their tax obligations legally. Your property’s cost base includes more than just the purchase price. Capital improvements, maintenance costs, and eligible deductions for depreciation and capital works all factor into your calculations. Building these costs into your records helps reduce your taxable capital gains while meeting ATO requirements for property investment taxation. The timing of your sale, your current marginal tax rate, and your property’s rental income history all influence your final CGT calculation.

Reducing your Capital Gains Tax liability (CGT) is possible with proper planning and by using things like exemptions and tax deductions.
Here are key strategies to help you lower the amount you pay when selling your investment property:
Property ownership duration and CGT discounts
If you’ve owned your investment property for more than a year as calculated from the contract date not the settlement date, you may qualify for the 50% Capital Gains Tax (CGT) discount. This significantly reduces your taxable capital gain and your overall Capital Gains Tax (CGT) liability. Carefully timing your sale to align with this threshold can make a big difference in the tax you pay.
Natural persons and trusts are eligible for the 50% discount. SMSFs get a 33% discount, however companies which own CGT assets such as land and buildings do not qualify for the CGT discount.
Main residence CGT exemption rules
Properties that were once your main residence may qualify for partial or full exemptions from Capital Gains Tax (CGT). This can apply if you previously lived in the property before renting it out within a six year period. Read our article How the “6-Year Rule” can reduce your Capital Gains Tax (CGT) to learn more. The Australian Taxation Office recognises this exemption, making it a valuable way to avoid Capital Gains Tax (CGT) on properties with dual purposes.
The six-year absence rule
If you rented out your former primary residence, you could claim a Capital Gains Tax (CGT) exemption for up to six years after moving out. Selling the property within this timeframe allows you to offset or eliminate CGT. This rule helps reduce tax liability on rental income properties used for temporary investment purposes. To learn more about how the six year rule works, read our article How the “6-Year Rule” can reduce your Capital Gains Tax (CGT).
Property cost base calculations
To minimise your taxable capital gain, include all allowable expenses in your property’s cost base. Items like legal fees, stamp duty, renovation costs, and sale costs lower the total net capital gain. Properly calculating these figures ensures you don’t overpay on your Capital Gains Tax (CGT) property obligations.
How to maximise your property’s cost base
Lowering your tax bill when selling property starts with knowing which expenses count toward your property’s total value. Adding these costs to your purchase price can significantly reduce the tax you’ll owe on your investment property sale.
Different types of expenses qualify and can help lower your tax when selling. Each qualifying cost you track and document helps maximise your tax benefits.
Costs you can add to your property’s tax base
Improvements
Upgrades like new kitchens, home extensions, or structural changes that make your property more valuable or last longer.
Legal fees
Essential costs when buying or selling, such as conveyancing fees needed to transfer ownership.
Advertising costs
Money spent marketing your property for sale, including your advertising campaigns and sales materials.
Agent’s commissions
Fees you pay real estate agents whether buying or selling the property.
Stamp duty
Property transfer tax paid during purchase – a major cost you can include.
Repairs and maintenance
While regular upkeep doesn’t count, big improvements or major repairs that boost your property’s value may qualify.
How a capital gains report can save you tax money
A capital gains reduction report, also known as a quantity surveyor’s report, provides a detailed review of your eligible costs to help minimise your tax and maximise your deductions when selling property.
Comprehensive cost review
List every allowable expense to ensure you claim all possible deductions.
Tax planning
Cost adjustments can help you time your property sale for better tax outcomes.
Audit protection
Ensure you meet the Australian Tax Office’s standards, giving you confidence during tax reviews or audits.
Which tax strategy suits your investment property?
Choosing the right Capital Gains Tax (CGT) approach affects your investment property’s tax outcome. Your personal situation and investment goals shape which method will deliver the best results.
Main residence exemption
This strategy eliminates your Capital Gains Tax when you sell a property that served as your primary residence. It works particularly well if you lived in the property before converting it to a rental. However, you can only claim this exemption for one property at a time, and you’ll need evidence like utility bills to prove it was your main home.
Six-year rule
You can keep your CGT exemption for up to six years while earning rental income from your former main residence. This suits temporary moves or shorter-term investment plans. Keep in mind that claiming another property as your primary residence during this period cancels the exemption on your rental.
50% CGT discount
By holding your investment property for over 12 months, you can halve your taxable capital gain. While this common strategy offers significant savings, remember that your marginal tax rate still applies to the remaining 50% of your capital gain, affecting your final CGT liability.
Case study: Reducing property Capital Gains Tax
John bought a Sydney investment property for $700,000 and sold it a decade later for $1.2 million, generating a $500,000 capital gain. To reduce his Capital Gains Tax (CGT), he used several key strategies.
By keeping the property for over 12 months, John qualified for the 50% CGT discount, cutting his taxable gain in half. He then added $60,000 in qualifying costs to his property’s base value, including legal fees, renovations, and selling expenses. Using a $20,000 capital loss from an earlier investment further reduced his tax bill.
These steps brought his taxable gain down to $200,000. With his 37% tax rate, John’s final CGT came to $74,000 – saving him more than $100,000 compared to his initial tax estimate. His approach shows how strategic planning and proper expense tracking can significantly lower an investor’s tax burden when paying Capital Gains Tax (CGT).
Steps on how to calculate Capital Gains Tax
You can work out your Capital Gains Tax (CGT) by following a clear process.
Here are the key steps to determine what you’ll need to pay:
Find your capital proceeds
Work out what you received from the property sale or CGT event. For properties sold below market value or given away, use the current market value as your proceeds.
Work out your cost base
Add up your property’s purchase price plus capital expenses, legal fees, stamp duty, and eligible maintenance costs. For properties bought before September 21, 1999, you can use indexed cost base instead of the CGT discount.
Calculate your gain or loss
Subtract your cost base from your capital proceeds. A higher sale price means a capital gain, while a lower one creates a capital loss.
Total all CGT events
Add up gains and losses from all your CGT events in the financial year.
Use your capital losses
Take away any capital losses from your gains. Start with carried-forward losses, using them first against gains that don’t qualify for CGT discounts.
Check your CGT discounts
For assets owned over 12 months, you might get a 50% CGT discount (individuals and trusts) or different rates for Self-Managed Super Funds. Remember, you can’t use both indexation and discounts.
Complete your tax return
Include your net capital gain or loss in your income tax return. You’ll pay tax on gains at your marginal tax rate, while losses can reduce future capital gains.
