Australia’s New 30% Capital Gains Tax Hits Low-Income Earners From July 2027

Australia’s government has overhauled capital gains tax rules in the 2026 budget, effective July 1, 2027. The 50% discount on long-term gains is being scrapped and replaced with cost base indexation tied to inflation, plus a 30% minimum tax rate on real gains. Low-income earners and first-home buyers face unintended consequences, including losing access to tax-free thresholds and lower tax brackets on investment gains.

What’s changing on July 1, 2027

Since 1999, Australian investors have applied a flat 50% discount to capital gains on assets held over 12 months. From July 1, 2027, this discount vanishes. The tax office will instead adjust your cost base upward using the consumer price index (CPI) to account for inflation. Any remaining gain is your real gain, taxed at your marginal rate or 30%, whichever is higher. This applies to property, shares, and other CGT assets. Existing properties purchased before the reform are largely grandfathered, keeping the old 50% discount.

Low-income households face a tax trap

A wife with under $10,000 annual income from bank interest and dividends normally pays no tax. Under the new rules, if she sells shares after June 30, 2027, she could owe 30% tax on the capital gain, even though her income is so low. She loses the benefit of both the tax-free threshold and the 16% tax bracket. This creates an unintended consequence: households ineligible for the age pension due to a spouse’s defined benefit income miss out on proposed pensioner exemptions.

Indexation can cut both ways

Treasury modelling shows indexation is not always worse than the old 50% discount. For a house held five years, the effective discount averaged 42% over the past 20 years; for ten years, 36%. Lower-growth assets may fare better under indexation than the flat 50% cut. Higher-growth assets will pay more tax. The outcome depends entirely on your rate of return and how long you held the asset. Investors should seek advice on whether selling before June 30, 2027 makes sense for their situation.

Shift toward dividend investing expected

The CGT reforms may accelerate a structural shift toward income-investing strategies. As the historical tax advantage of capital growth narrows, investors may increasingly favour dividend-paying companies and franked income streams over speculative growth and small-cap investments. Australian equities underperformed global markets for a fourth consecutive year in FY26, but income-oriented strategies outperformed the broader local market. The new tax regime may make after-tax income returns more attractive than pure capital gains.

Final Thoughts

The CGT overhaul reshapes investment incentives from July 2027, with winners and losers depending on asset type, holding period, and income level. Low-income earners face an unintended tax squeeze, while dividend strategies may gain appeal. Investors should model their specific holdings before the cutoff date.
