Zero Capital Gains Rate in Australia: Policy Prospects & Impact in 2026

Australia’s capital gains tax (CGT) is not a separate tax, but profits from the sale of investments (like shares, property, or crypto) are added to your assessable income and taxed at your marginal rate. There are some key features:

• 50% Discount: If you hold an asset for more than 12 months, individuals and trusts can reduce their capital gain by 50% before tax is applied.

• Superannuation Funds: Funds enjoy a 33.3% discount on assets held longer than a year.

• Exemptions: Your primary residence is typically exempt, but investment properties and shares are not.

With property and share prices rebounding in 2026, many Australians are set to realise significant gains, making CGT more relevant than ever.

The concept is simple: eliminate tax on profits from the sale of investments. In practice, it could take several forms:

• Complete abolition of CGT for individuals, trusts, and companies.

• Targeted zero rates for certain assets (e.g., startups, green investments, or first-home buyers selling their first property).

• Time-limited zero rates to encourage investment during periods of economic slowdown.

Internationally, countries like New Zealand have no broad-based CGT, while others (like Singapore) offer zero or reduced rates for long-term investments. The debate in Australia has heated up as policymakers look to spur economic growth and attract global capital in a post-pandemic environment.

Adopting a zero capital gains rate would have far-reaching implications:

Winners

• Everyday investors could see greater returns and more flexibility in managing their portfolios.

• Startups and small business owners might find it easier to attract venture capital, as investors would keep more of their exit profits.

• Retirees and super funds could benefit from higher after-tax returns, supporting better retirement outcomes.

Losers

• The Federal Budget would take a hit—CGT raised over $20 billion in 2023-24, funding schools, hospitals, and infrastructure.

• Property affordability could worsen if investors flood the market, driving up prices further.

• Wealth inequality may widen, as wealthier Australians are more likely to own assets that attract capital gains.

Some economists argue that zero CGT could increase economic dynamism, while others warn it might encourage speculation and short-termism, undermining market stability.

While no major party has tabled a zero CGT bill, the idea is on the radar. The Federal Treasury’s 2026 review of Australia’s tax system is examining the efficiency and fairness of existing CGT rules. There is mounting pressure from business groups and some crossbench senators to consider targeted CGT relief for startup founders and green investment projects.

At the same time, the Albanese Government is focused on housing affordability and closing tax loopholes, making a blanket zero CGT rate unlikely in the short term. However, the conversation is not going away—especially as Australia seeks to stay competitive in a region where capital is increasingly mobile and tax competition is fierce.

Investors should stay alert to policy developments, as any CGT changes will have major implications for portfolio strategy, property investment, and superannuation planning in the years ahead.

To better understand the potential effects of a zero capital gains rate, let's explore some practical scenarios:

Scenario 1: Selling an Investment Property

Imagine an investor, Jane, who purchased an investment property in Sydney for $500,000 in 2015. By 2026, the property's value has increased to $800,000. Under the current system, Jane would pay CGT on the $300,000 gain, reduced by the 50% discount if held for over a year. However, with a zero capital gains rate, Jane retains the entire $300,000 gain, significantly boosting her reinvestment capacity or retirement savings.

Scenario 2: Startup Exit

Consider a tech entrepreneur, Alex, who started a company in Melbourne. After five years, Alex sells the business for a substantial profit. With no CGT, Alex keeps more of the proceeds, which could be reinvested into new ventures or used to support local economic growth. This scenario highlights the potential for increased entrepreneurial activity and innovation.

Portfolio Diversification

Investors should consider diversifying their portfolios to mitigate risks associated with potential policy changes. A mix of property, shares, and other assets can provide stability and growth opportunities.

Stay Informed

Keep abreast of policy developments by following updates from authoritative sources like the Australian Taxation Office (ATO) and the Australian Securities and Investments Commission (ASIC). Engaging with financial advisors who understand the evolving tax landscape can also be beneficial.

Long-term Planning

Consider the implications of a zero CGT rate on long-term financial planning. While the prospect of higher after-tax returns is appealing, it's crucial to balance this with potential risks, such as increased market volatility or changes in government policy.

What is Capital Gains Tax (CGT)?

Capital Gains Tax is the tax you pay on profits from selling assets like property, shares, or businesses. It's calculated on the difference between the sale price and the purchase price, with certain discounts available for long-term holdings.

How does a zero capital gains rate benefit investors?

A zero capital gains rate allows investors to retain all profits from asset sales, increasing their disposable income and investment capacity. This could lead to greater financial flexibility and enhanced portfolio growth.

Are there any downsides to a zero capital gains rate?

While beneficial for investors, a zero capital gains rate could reduce government revenue, impacting public services and infrastructure funding. It may also exacerbate wealth inequality and drive up property prices, affecting affordability.

What should I do to prepare for potential CGT changes?

Stay informed about policy updates and consider consulting a financial advisor to understand how changes might affect your investment strategy. Diversifying your portfolio and planning for the long term can help mitigate risks.
