From 1 July 2026, Australian property investors face updated capital gains tax (CGT) thresholds, revised discount rules for certain trusts, and stricter ATO data-matching on property transactions – changes that make working with a qualified accountant more important than ever. Understanding how these updates affect your investment strategy could save you thousands of dollars at tax time.
Capital gains tax changes for Australian property investors in 2026 – 2026 AU guide
What has actually changed with CGT in 2026?
Always verify the current rules with the ATO before acting – capital gains tax settings, trust integrity measures and data-matching programs are routinely updated. The headline 50% CGT discount for individuals who have held an asset for more than 12 months remains an entrenched feature, but additional integrity rules and record-keeping requirements apply for discretionary trusts claiming the discount on property disposals.
The ATO operates expanding data-matching programs covering state and territory land title offices, rental bond authorities and share registries – the agency publishes annual outcomes and the scope of each program. For property investors, this means undeclared sales or incorrectly calculated cost bases are far more likely to be detected than they were even two years ago. See the ATO data-matching protocols page for the current program list.
Investors selling property used partly for private purposes – such as a holiday home occasionally rented out – must apportion their cost base and capital proceeds. The ATO publishes capital gains tax guidance on accepted apportionment methodologies – check that page for current rulings and Practical Compliance Guidelines.
How the 50% CGT discount works – and who qualifies
The 50% CGT discount is one of the most valuable concessions available to Australian property investors. If you are an individual or a beneficiary of a trust and you have owned an investment property for more than 12 months before selling it, only half of your net capital gain is included in your assessable income. Superannuation funds qualify for a one-third discount rather than half, while companies receive no discount at all.
To access the discount in 2026, you must:
- Be an Australian resident for tax purposes at the time of the CGT event - Have held the asset for at least 12 months (calculated from the contract date of purchase to the contract date of sale) - Not be in the business of property development or trading (in which case profits are treated as ordinary income, not capital gains)
If your property was acquired before 21 September 1999, you may also be eligible to use the indexation method instead of the discount method – whichever produces the better outcome.
Working with one of the best accountants in Sydney or in your local area can help you model both methods before you commit to a sale strategy.
Calculating your capital gain – common mistakes investors make
Your net capital gain is your capital proceeds minus your cost base. The cost base is broader than simply the purchase price. It includes:
- Stamp duty and conveyancing costs paid at purchase - Capital improvements made to the property (not deductible repairs) - Costs of sale such as agent commissions and legal fees - Borrowing costs not otherwise deducted (where applicable)
One of the most frequent mistakes the ATO identifies is investors forgetting to reduce their cost base by any depreciation deductions already claimed through a quantity surveyor's report. If you have claimed building write-off (Division 43) deductions over several years, those amounts reduce your cost base, increasing the eventual capital gain. Australia has a large investor-property cohort (see ATO Taxation Statistics for current rental-schedule counts) – and a significant proportion of those investors have never reviewed their depreciation schedules in relation to their eventual CGT liability.
Negative gearing losses carried forward do not offset capital gains directly; they offset your taxable income in the year they are incurred. Understanding this distinction matters enormously when planning a sale, and an experienced property accountant can model the timing of a disposal to minimise your combined tax position.
The main residence exemption – partial exemptions and traps
The main residence exemption can fully or partially exempt a property from CGT if it has served as your principal place of residence. However, several scenarios create only partial exemptions and catch investors off guard:
Renting out your former home: If you move out and rent the property, the "absence rule" allows you to treat the property as your main residence for up to six years, provided you do not nominate another property as your main residence simultaneously. If you sell within that six-year window, full exemption may still apply. Purchasing before selling: If you are building or purchasing a new home before selling the old one, you can hold two main residences simultaneously for up to six months without losing the exemption on either. Airbnb and short-term rental: Using part of your home for income-generating purposes – even occasionally – creates a partial CGT liability. The ATO receives data directly from short-term rental platforms and will cross-reference this against your tax return.Review our cost guide if you are unsure whether engaging a tax accountant for a partial exemption calculation is worth the fee – in most cases involving a property worth $700,000 or more, it absolutely is.
Comparing your options: DIY, tax agent, or specialist property accountant
Choosing how to manage your CGT obligations involves balancing cost against complexity and risk. The table below compares your three main options in 2026:
| Option | Typical AUD cost (2026) | Best suited to | Key risk | |---|---|---|---| | DIY via myTax | $0 – $50 (software) | Simple single-property sale, no partial exemptions | Errors in cost base; missed concessions | | General tax agent / H&R Block style | $300 – $800 per return | One or two properties, straightforward history | May lack specialist property CGT knowledge | | Specialist property accountant | $1,200 – $3,500+ per engagement | Multiple properties, trusts, development activity, partial exemptions | Higher upfront cost; ensure they hold a current CPA or CA designation |For most investors selling property with a gain above $100,000, the fee charged by a specialist accountant is likely to be recovered many times over through correct cost base construction, timing advice, and concession eligibility assessment.

What to ask your accountant before you sell
Before engaging an accountant or proceeding with a sale, prepare to discuss:
1. Your full ownership history – dates, prices, structural improvements, and any periods of private use 2. Your marginal tax rate – because CGT is added to your other income, the timing of a sale can push you into a higher bracket 3. Trust or company structures – if the property is held in a trust or SMSF, different rules and discount rates apply 4. State land tax obligations – while not CGT, land tax liabilities can affect net proceeds and should be factored into any sale modelling
FAQ
Q: Is the 50% CGT discount being abolished? A: There is periodic public debate about the discount, but the 50% CGT discount for individuals holding assets for more than 12 months remains an entrenched feature of Division 115 of the ITAA 1997. Current changes generally relate to trust integrity measures and ATO data-matching rather than the individual discount rate – check the ATO CGT discount page for the current position. Q: Do I pay CGT if I transfer investment property to my spouse? A: A transfer between spouses is generally a CGT event, though rollover relief may be available in the context of a relationship breakdown under Section 126-5 of the ITAA 1997. In other circumstances, the transfer is treated as a disposal at market value and CGT applies – seek advice before proceeding. Q: How long do I need to keep records related to a property sale? A: The ATO requires you to keep records for five years after you lodge the tax return in which you report the capital gain or loss. For properties held for many years, this means retaining purchase records, renovation invoices, and loan documents potentially for decades. Q: Can I offset a capital gain on an investment property with a capital loss on shares? A: Yes. Capital losses from any source – including shares, managed funds, or other assets – can be applied against capital gains on property in the same income year. Unused capital losses are carried forward indefinitely and applied against future capital gains.---
