Investing in shares is a popular way for Australians to build wealth, but with the potential for profits also comes the responsibility of tax compliance. Understanding how much tax you pay on shares in Australia can be crucial in shaping your investment strategies and maximising returns. In the points below, we break down what taxes apply, how they are calculated, and what you need to know as a shareholder in Australia.
Capital Gains Tax (CGT) on Shares
One of the most significant taxes associated with shares in Australia is Capital Gains Tax (CGT). When you sell shares at a profit, the gain is generally considered part of your taxable income and is subject to CGT – here’s how it works:
- Short-term vs Long-term Investments: If you hold shares for less than 12 months before selling them, the entire profit from the sale is subject to tax at your marginal income tax rate. However, if you hold your shares for more than 12 months, you may be eligible for a 50% CGT discount. This means you’ll only pay tax on half of the capital gain, which can make a substantial difference.
- Calculating CGT on Shares: The gain is calculated by subtracting the purchase price (plus any associated costs like brokerage fees) from the sale price. It’s essential to keep accurate records of purchase and sale transactions, as these figures are needed to determine the gain and your tax liability.
- Losses Offset Gains: If you incur a capital loss from selling shares, it can be used to offset capital gains made on other investments. If your losses exceed your gains, you can carry them forward to offset future gains, which can help reduce your tax in years when you’ve profited from other investments.
Dividend Income and Franking Credits
In addition to capital gains, shareholders are also liable for tax on any dividend income they receive – dividends are typically paid out of a company’s profits and can be either franked or unfranked.
- Franking Credits on Dividends: Franked dividends come with a tax credit, known as a franking credit, which represents the company tax already paid on that profit. When you declare the dividend income in your tax return, you may be eligible to claim this franking credit as a tax offset, reducing your overall tax liability.
- Unfranked Dividends: Unfranked dividends do not have a tax credit attached, meaning you will be required to pay tax on the full dividend amount at your marginal tax rate.
Tax Rates and Brackets for Shareholders
The amount of tax you’ll pay on shares in Australia depends on your income level. Australia operates on a progressive income tax system, so the higher your taxable income, the higher your tax rate.
- Marginal Tax Rates: Individual income tax rates apply, meaning that any capital gains or dividends will be taxed at your marginal rate. Understanding how much tax you pay on shares in Australia involves knowing where your income falls within the tax brackets for that financial year.
- Self-Managed Super Funds (SMSFs): If you hold shares within an SMSF, the tax implications differ. SMSFs benefit from a lower tax rate of 15% on income and can also access a one-third CGT discount if they hold assets for over a year, making them an appealing option for retirement savings.
Reporting and Paying Tax on Shares
Tax on shares must be reported in your annual tax return – here are some essential steps to follow:
- Keep Accurate Records: Document all purchase and sale transactions, dividend statements, and any costs related to buying or selling shares. These records are critical in calculating your CGT and declaring your dividend income accurately.
- Declare Capital Gains and Dividends: Include any capital gains or dividends as part of your taxable income. Your tax return should show all income from shares, including any franking credits.
- Use Tax Offsets and Concessions Where Eligible: Take advantage of the 50% CGT discount if you qualify and claim franking credits for dividends to reduce your overall tax bill.

Navigating Tax on Shares with Confidence
Understanding the tax implications on shares is essential for any investor. Taxes can significantly impact your investment returns, but by knowing the rules around CGT, dividend income, and offsets like franking credits, you can make informed decisions and structure your portfolio to suit your financial goals.
