Australia’s Capital Gains Tax Overhaul: What the 2026 Budget Means, June 06

Australia’s 2026 Federal Budget introduces one of the most significant tax reforms in decades. Treasurer Dr Jim Chalmers announced plans to abolish the long-standing 50% capital gains tax (CGT) discount and replace it with an inflation-indexed system and a 30% minimum tax floor. The changes take effect July 1, 2027, and will directly affect how Australians calculate gains on investments, property, and business sales.

How the New CGT System Works

Under the new rules, the cost base of an asset will be adjusted for inflation before tax is calculated. The 50% CGT discount disappears entirely for assets held over 12 months. A 30% minimum tax floor applies to all capital gains realised after July 1, 2027.

A limited exemption allows newly built residential properties to choose between the old and new methods. This gives some property investors a transition window, but the flat discount is gone for most taxpayers.

Trusts Face Steeper Tax Burden

Discretionary trusts will face a 30% minimum tax on taxable income from July 1, 2028. This significantly reduces the tax flexibility trusts have historically offered. Distributions to low-income beneficiaries, retirees, and minors will be taxed at the 30% minimum, eliminating tax credits that exceed that rate.

Corporate beneficiaries face an effective tax rate of 51% on trust income. SME owners using trusts for tax planning must now review whether their current structure remains suitable for business and family needs.

Who Gets Hit Hardest

Low-income individuals and retirees receiving trust distributions lose the most. They will pay 30% tax on income they might normally pay 15% or less on, with no refund of excess tax credits. Families using trusts to split income across multiple beneficiaries lose a key planning tool.

Investors holding long-term assets will see higher tax bills when they sell. The inflation indexation method may provide some relief in high-inflation years, but the 30% floor removes downside protection.

What Investors Should Do Now

Investors have until July 1, 2027, to plan. Consider realising capital gains before the new rules take effect if you have losses to offset. Review trust structures with an accountant to assess whether distributions to beneficiaries will trigger the 30% minimum tax.

For newly built residential properties, accountants recommend documenting the choice between old and new methods before July 1, 2027. Business owners should stress-test their exit strategies under the new tax regime.

Final Thoughts

The 2026 Budget fundamentally shifts Australia’s tax system away from discounts toward minimum tax floors. Investors and trust beneficiaries face higher tax bills, especially on long-held assets and low-income distributions. Plan ahead before July 1, 2027.
