The Death of the 50% CGT Discount
The historic 50% Capital Gains Tax discount is being abolished. Find out how this historic 2027 reform impacts your investment property and what you must do to protect your wealth.
Announced in the May 2026 Federal Budget, the Australian government is introducing the most radical reforms to Capital Gains Tax (CGT) in four decades. From 1 July 2027, the beloved 50% discount will officially end.
Why is the 50% Discount Being Abolished?
Since its introduction in 1999, the 50% CGT discount has allowed property investors and share traders who hold an asset for more than 12 months to pay tax on only half of their capital profit. To curb housing speculation and shift the tax base toward compound inflation offsets, the government is replacing the flat discount with an indexed compound inflation model.
The New Regime: CPI Cost Base Indexation
Instead of discounting your profits, the new rules adjust your initial cost base for CPI inflation over the period of ownership. While this protects you from paying tax on paper profits caused by general inflation, it eliminates the massive tax concessions enjoyed on high-growth assets.
How Transitional Split-Treatment Saves You
Thankfully, the government is introducing transitional rules to avoid retrospectively taxing wealth accumulated prior to the reform. If you purchased your property before 1 July 2027 and sell after, your gain is divided:
- Pre-Reform Portion: Fully eligible for the legacy 50% discount.
- Post-Reform Portion: Subject to the new CPI indexation and 30% floor tax.
⚠️ The Crucial Lock-in Method
To lock in your pre-reform gains under the 50% discount, you can use the Market Valuation Method. This requires a formal registered property valuation as of 1 July 2027. Without it, you are forced to use day apportionment, which assumes linear growth and can cost you thousands if your property grew faster in the early years.
Three Action Items You Must Do Now
To prepare for the transition, investors should begin planning immediately:
Audit Your Historical Receipts
Collect every purchase invoice, stamp duty receipt, and renovation invoice. A flawless digital cost base ledger is the only defense you have to lower your future tax margins.
Pre-Book a 1 July 2027 Property Valuation
Property valuers will be swamped in mid-2027. Lock in a professional surveyor in advance to ensure you have a certified legal record of your property value on the exact transition date.
Simulate Your Tax Strategy
Run different sale dates and inflation percentages to see if selling before or after 1 July 2027 yields a better after-tax outcome.
