How Australia’s CGT Overhaul Reshapes Value Investing Strategy

The 2026 Federal Budget has introduced the most significant changes to Australia’s investment taxation system in decades, with profound implications for value investing strategies. The replacement of the 50 per cent capital gains tax discount with an inflation-indexation model and a 30 per cent minimum tax floor represents a fundamental shift in the calculus between income and capital growth.

What Has Changed

Under the previous system, Australians who held investments for more than 12 months generally paid tax on only half of their capital gain. The new regime, effective for gains accruing from 1 July 2027, adjusts the original purchase price for inflation before calculating the taxable gain, while simultaneously applying a 30 per cent minimum tax on real capital gains for most investors outside superannuation.

The practical impact can be illustrated simply: under old rules, a $10,000 gain would be taxed on $5,000. Under the new rules, with 3 per cent annual inflation over a decade, the taxable gain would rise to approximately $6,561—a 31 per cent increase in the taxable amount.

The Value Investing Advantage

This tax reform creates a structural advantage for value-oriented portfolios. As Reece Birtles of ClearBridge Investments observed, the changes “further incentivise investing for profits and income over future capital gains”. Value stocks, by their nature, tend to pay higher dividends and generate more immediate income relative to growth stocks, which derive a greater proportion of returns from capital appreciation.

The minimum 30 per cent tax floor substantially reduces the ability to time asset sales to low-income years—a strategy that historically benefited growth investors who could defer capital gains until retirement. With this option curtailed, the relative appeal of dividend-paying value stocks increases materially.

Sector Implications

The tax changes are likely to accelerate the rotation already underway in Australian equity markets. Growth funds were among the poorest performers in FY26, with Hyperion Asset Management’s Small Growth Companies Fund declining 34.3 per cent and its Australian Growth Companies Fund falling 29.2 per cent.

Conversely, value-oriented strategies that emphasise earnings resilience and dividend income stand to benefit. Sectors such as banking, energy, and infrastructure—which typically offer higher yields and more predictable earnings—become more attractive relative to technology and other growth-oriented sectors.

Practical Portfolio Considerations

The transition period to 1 July 2027 provides a window for investors to reassess their portfolios. For assets already held, gains accrued up to that date may continue to access the previous 50 per cent discount, while gains accruing afterwards fall under the new indexed regime. Investors will need to establish the value of their assets on 1 July 2027 to determine the split between the two periods.

The franking credit system, which provides a structural tax advantage for ASX equities over global holdings, remains unchanged. This further reinforces the case for domestic value stocks, particularly those offering fully franked dividends.

For value investors, the CGT overhaul represents not merely a tax adjustment but a strategic inflection point. The relative attractiveness of income-generating, fairly valued businesses over speculative growth stories has been structurally enhanced, creating a tailwind for disciplined value strategies that was absent in the previous tax regime.
