The recent Federal Budget announcements present sweeping changes to how investment returns are taxed in Australia. For those holding property or shares, the proposed adjustments to the Capital Gains Tax framework represent a significant structural shift. It is important to state clearly upfront that these measures are currently proposals and are not yet law. They require parliamentary approval before taking effect.
Replacing the 50 Per Cent Discount
Under the current system, an investor who holds an asset for more than 12 months generally receives a 50 per cent discount on the capital gain upon sale. The government intends to remove this discount from 1 July 2027.
Instead, the system will return to an inflation-based indexation model, similar to the rules in place prior to 1999. When calculating the taxable profit, the original purchase price of the asset will be adjusted upwards in line with the Consumer Price Index. Investors will then only pay tax on the real increase in the value of the asset above that inflation adjusted cost base.
Understanding the 30 Per Cent Minimum Tax
Alongside indexation, the budget proposes a minimum 30 per cent tax rate on those real capital gains, applying from 1 July 2027. If an investor’s marginal tax rate on their capital gain falls below 30 per cent, they will be required to pay a top up tax to reach that threshold.
Analysis provided by the ASX illustrates the financial impact of this measure. Consider an investor with a taxable income of $25,000 who realises a capital gain of $10,000 on an asset purchased after July 2027. Normally, the tax on that gain for someone in this tax bracket might be $1,400, reflecting an effective rate of 14 per cent. Under the proposed rules, the investor must pay an additional $1,600 to bring the total tax on the gain up to $3,000, ensuring the 30 per cent minimum is met.
The intent is to deter investors from deferring the sale of assets to years when their regular income is low, such as during early retirement. It is worth noting that individuals receiving means tested government income support payments, such as the Age Pension, are exempt from this minimum tax.
Legacy Assets and Transitional Rules
A major surprise in the budget was the removal of the permanent blanket exemption for legacy assets acquired before 20 September 1985. As detailed by Pitcher Partners, from 1 July 2027, these legacy assets will be brought into the tax net.
The capital gains that have accrued on these assets up until 1 July 2027 will remain permanently exempt. However, the asset’s cost base will effectively be reset to its market value on that date. Any subsequent growth in value after 1 July 2027 will be subject to the new indexation and 30 per cent minimum tax rules.
For assets purchased after September 1985 but before 1 July 2027, transitional rules will apply. Investors will receive the 50 per cent discount on the portion of the gain that accrued up to 1 July 2027. Any value gained after that date will fall under the new indexation rules. This will require investors to either obtain a formal market valuation as of 1 July 2027 or use an apportionment formula provided by the tax office.
Real World Scenarios
For property investors, the distinction between established and newly built housing is vital. According to Chartered Accountants ANZ, the government has carved out an exception to support housing supply.
If an investor purchases a newly built residential property that genuinely adds to the housing stock, they will have the unique option to choose between the old 50 per cent discount or the new indexation and minimum tax model. Importantly, this choice is limited strictly to the original purchaser of the new build. It does not extend to subsequent buyers who purchase the property second hand at a later date.
Strategic Next Steps
While 1 July 2027 may seem distant, the transition to an inflation adjusted model with a firm minimum tax rate alters the mathematics of wealth creation. The removal of exemptions for pre 1985 assets means that thousands of portfolios will need careful reassessment.
For anyone holding significant growth assets, establishing the value of those investments near the 1 July 2027 transition date will be essential for accurate future reporting. Speaking with a qualified tax professional or financial advisor early will help clarify exactly how these impending changes will alter long term financial planning.
