How Australian Tax Works on Foreign Shares

Australia taxes its residents on their worldwide income. This means if you live in Australia and own shares in a US company, a UK-listed ETF, or any other foreign investment, the income from those shares is assessable in Australia. The ATO requires you to declare foreign dividends, capital gains, and any other returns on your annual tax return.

The key difference from Australian shares is that foreign shares don't come with franking credits. Australian shares have a dividend imputation system where the company pays tax on its profits and attaches franking credits to dividends. Foreign companies typically don't participate in this system, so you can't claim franking credits on foreign dividends. However, you may have already paid foreign withholding tax on those dividends, which brings us to the foreign income tax offset.

If you hold foreign shares through a managed fund or an Australian-listed ETF that invests internationally (like VGS or BGBL), the fund manager handles much of this complexity. They calculate the foreign income component and any foreign tax credits for you, which are then reported on your annual tax statement. This makes it simpler for everyday investors who want international exposure without managing individual overseas share accounts.

Foreign Dividend Taxation Explained

When a foreign company pays you a dividend, the amount you receive is often reduced by foreign withholding tax. The rate depends on the tax treaty between Australia and the country where the company is based. For example, US dividends typically have 15% withholding tax under the US-Australia tax treaty, while without the treaty it would be 30%. This tax is paid to the foreign government before the dividend reaches your bank account.

Here's how the ATO treats foreign dividends. You declare the gross dividend amount (before withholding tax) as assessable income on your tax return. Then, you claim a foreign income tax offset (FITO) for the tax already paid to the foreign government. If your Australian marginal tax rate is higher than the foreign withholding rate, you'll pay Australian tax on the difference. If it's lower, the offset covers your Australian tax liability, but unlike franking credits, the FITO is non-refundable — you won't get a refund for excess foreign tax credits.

In this example, your effective tax rate on the dividend is 30% (your Australian marginal rate), but you've only paid 15% directly. The foreign income tax offset reduces your Australian tax bill by the $150 already paid to the US government. Your total tax paid is $300, split between $150 to the US and $150 to Australia. Some countries also have capital gains taxes, and you may need to manage your overall income tax position carefully when investing across multiple jurisdictions.

Capital Gains Tax on Foreign Shares

When you sell foreign shares at a profit, Australian CGT applies to the gain. The cost base is the Australian dollar value of the shares when you bought them, and the sale proceeds are the Australian dollar value when you sold them. You must convert all foreign currency amounts to AUD using the exchange rates on the transaction dates. The ATO publishes monthly exchange rates for this purpose, or you can use the actual exchange rate from your broker statement.

The 50% CGT discount applies to foreign shares held for more than 12 months, just as it does for Australian assets. This means if you've held foreign shares for at least a year before selling, you only include 50% of the capital gain in your assessable income. If you've made a capital loss on foreign shares, you can offset it against capital gains from other investments, but you can't offset capital losses against your salary or dividend income.

One important aspect of foreign shares is currency fluctuations. Even if the share price in the foreign currency stays the same, the AUD value of your investment changes with exchange rates. The ATO treats these currency gains or losses as part of your CGT calculation. If you hold the shares for investment purposes rather than currency speculation, these currency movements are captured within the CGT framework rather than being treated as separate foreign exchange gains.

Using the Foreign Income Tax Offset (FITO)

The foreign income tax offset (FITO) is the mechanism that prevents double taxation on your overseas investments. It's calculated as the lesser of the foreign tax paid and the Australian tax payable on that foreign income. This ensures you never pay more in combined tax than the higher of the two rates, but you also can't get a refund if the foreign tax rate is higher than your Australian rate.

To claim the FITO, you need to fill out the relevant section of your tax return with the details of each foreign income source and the tax paid. You'll need supporting documents like dividend statements from the foreign company or your broker showing the withholding tax deducted. For managed funds and ETFs, your annual tax statement from the fund manager will include this information broken down by country.

There's a simplified method available if your total foreign income tax offset is $1,000 or less across all foreign investments. In this case, you don't need to itemise each source separately — you can claim the total as a single figure. If the offset is more than $1,000, you need to provide detailed breakdowns. This is one area where using our take-home pay calculator alongside your investment planning can give you a clearer picture of how foreign income affects your overall tax position.

Foreign Shares and Your Other Tax Obligations

Foreign dividend income affects several other tax obligations you need to be aware of. Your worldwide income, including foreign dividends and capital gains, counts toward the income thresholds for the Medicare levy. The 2% Medicare levy applies to your total taxable income, including overseas investment returns, once your income exceeds the threshold of approximately $27,222 for FY 2025-26.

If you have a HECS-HELP debt, your repayment income includes all foreign-source income as well. This means foreign dividends and capital gains can push you into a higher repayment bracket or trigger HECS repayments if you're near the threshold. The HECS repayment threshold for FY 2025-26 is $67,000, with rates increasing progressively up to 10% for incomes over $179,286.

Your superannuation contributions are unaffected by foreign income directly, but your total taxable income determines how much you can contribute under the concessional cap ($30,000 for FY 2025-26) and the non-concessional cap ($120,000). If you're considering salary sacrificing to super, remember that foreign investment income doesn't reduce your PAYG withholding or salary, but it does add to your total assessable income for purposes like the Medicare Levy Surcharge.

Reporting Foreign Shares on Your Tax Return

Reporting foreign shares on your Australian tax return requires careful record-keeping. You need to track the purchase date, purchase price in foreign currency, the AUD equivalent at the time of purchase, dividends received (gross and net), foreign withholding tax paid, and any brokerage or transaction fees. The more organised your records, the easier your annual tax return becomes.

For shares held through a brokerage that offers international trading (like Commsec International, Interactive Brokers, or Stake), your annual trading report often includes AUD conversions and summaries of dividends and withholding tax. However, you're ultimately responsible for the accuracy of your tax return, so it's worth cross-checking broker reports against the source documents. If your total foreign investments are significant, consider using tax software or a registered tax agent who specialises in international tax matters.

Don't forget about foreign exchange reporting requirements. If you have a foreign bank account or brokerage account holding over AUD $100,000 at any point during the financial year, you must report it separately. The ATO automatically receives financial account information from over 100 countries through the Common Reporting Standard (CRS), so it's important to be accurate and complete in your reporting to avoid compliance issues and potential penalties.

Tax-Effective Strategies for Foreign Shares

One common strategy for Australian investors is using Australian-domiciled ETFs that invest in international shares. Funds like VGS, IVV, and BGBL offer international exposure but are structured as Australian trusts. They handle the foreign tax complexities internally, and you receive a simplified tax statement each year. The dividends are classified as foreign-sourced income but the fund manages the FITO calculations, making your tax return much simpler.

Another consideration is the currency risk and timing of your investments. If you believe the AUD will strengthen against the US dollar, the value of your US shares in AUD terms will decrease even if the US share price stays flat. Some investors use currency hedging through hedged ETFs (like IHWL or HGBL) to neutralise this risk, though hedging costs can reduce returns over time. For long-term investments, unhedged exposure can provide natural diversification benefits.

If you're earning significant foreign dividends, consider how your investments interact with salary sacrifice arrangements. While salary sacrificing reduces your employment income for tax purposes, your foreign investment income remains taxable at your marginal rate. Combining salary sacrifice with international investments can be an effective strategy if you're in a high tax bracket and looking to optimise your overall tax position across all income sources.

Frequently Asked Questions

Do I need to pay Australian tax on foreign shares?

Yes, Australian residents are taxed on their worldwide income, including dividends and capital gains from foreign shares. You declare this income on your Australian tax return and pay tax at your marginal rate, but you can claim a foreign income tax offset for any tax already paid overseas.

How is foreign withholding tax on dividends treated in Australia?

Foreign withholding tax paid on dividends is claimed as a foreign income tax offset (FITO) on your Australian tax return. This offset reduces your Australian tax liability by the amount of tax already paid overseas, preventing double taxation. Unlike franking credits, the FITO is non-refundable.

What is the US-Australia tax treaty rate for dividends?

Under the US-Australia tax treaty, the withholding tax rate on dividends is generally 15% for Australian residents. Without the treaty, the US would withhold 30%. You need to file a W-8BEN form with your US broker to claim the reduced treaty rate.

Can I use the 50% CGT discount on foreign shares?

Yes, the 50% CGT discount applies to foreign shares held for more than 12 months, just as it does for Australian assets. The discount applies to the capital gain calculated in AUD, after accounting for currency fluctuations between purchase and sale.

Do I need to report foreign shares if they're held in an Australian brokerage?

Yes, you still need to declare income from foreign shares on your tax return, even if you bought them through an Australian broker like Commsec or CMC Markets. The ATO requires you to report all foreign-source income regardless of where the shares were purchased. Your broker's annual statement will include the foreign income components.
