Introduction
As a South African business owner, navigating the complexities of foreign income tax South Africa is essential for staying compliant with SARS and avoiding costly penalties. Whether you run an export business, earn dividends from offshore investments, or receive royalties from international clients, understanding how your foreign earnings are taxed locally can save you thousands of rands. At Blu Solutions, we specialise in helping businesses across Mossel Bay, George, Knysna, and Cape Town manage cross-border tax obligations seamlessly. In this comprehensive guide, we break down everything you need to know about taxing foreign income in South Africa — from residency rules to double taxation agreements (DTAs) and practical filing tips.
1. Who Must Declare Foreign Income in South Africa?
South Africa taxes its residents on their worldwide income. This means if you are a South African tax resident, all foreign earnings — regardless of where they are sourced — must be included in your annual tax return. The key factor is your residency status, not where the money is earned.
What Determines Tax Residency?
SARS uses two main tests to determine residency:
- Ordinarily Resident Test: You are considered a resident if South Africa is your true home — where you live, work, and have your family and economic ties.
- Physical Presence Test: If you are not ordinarily resident, you become a resident if you were physically in South Africa for more than 91 days in the current tax year, and more than 91 days in each of the previous five tax years, totalling at least 915 days over that five-year period.
Practical tip: If you spend significant time abroad for business, keep a detailed travel diary. SARS may request proof of days spent in and out of the country.
2. Types of Foreign Income Subject to Tax
Not all foreign income is treated the same. Here are the most common categories that South African business owners need to report:
- Foreign business profits: Income from a foreign branch or subsidiary.
- Foreign dividends: Dividends received from non-South African companies.
- Interest and royalties: Interest on offshore savings accounts or royalties from intellectual property used abroad.
- Rental income: Property rentals from overseas real estate.
- Capital gains: Profits from selling foreign assets such as shares or property.
Example: If you own a rental apartment in London and earn R150,000 in rental income annually, that amount must be declared in your SARS return. You may be able to claim a foreign tax credit for UK taxes paid (see Section 4).
3. The Foreign Employment Income Exemption (Section 10(1)(o)(ii))
For employees who work outside South Africa for more than 183 days in a 12-month period (with at least 60 continuous days abroad), the first R1.25 million of foreign employment income may be exempt from South African tax. However, this exemption does not apply to business owners who are self-employed or earn income through a company they control — it is strictly for employees.
Important change: From 1 March 2020, the exemption is capped at R1.25 million. Any foreign employment income above that threshold is fully taxable in South Africa. Business owners earning through their own company should consult a tax professional to structure their affairs correctly.
4. Double Taxation Agreements (DTAs) and Foreign Tax Credits
South Africa has signed DTAs with over 70 countries to prevent the same income from being taxed twice. If you pay tax on foreign income in another country, you can claim a foreign tax credit in South Africa — but only up to the amount of South African tax payable on that income.
How to Claim a Foreign Tax Credit
- Complete the relevant section in your tax return (ITR12 for individuals).
- Attach proof of foreign tax paid (e.g., a tax assessment from the foreign revenue authority).
- Ensure the foreign tax is a final tax (not a provisional payment).
Example: You earn R500,000 in consulting fees from a US client and pay R75,000 in US federal tax. Your South African tax on that income is R100,000. You can claim a credit of R75,000, so you only pay R25,000 to SARS.
5. Exchange Control Regulations and Reporting
While South Africa’s exchange control rules have been liberalised, business owners must still comply with certain reporting requirements when moving funds abroad. The South African Reserve Bank (SARB) requires that:
- Foreign capital (e.g., investments) be reported via a Tax Clearance Certificate for International Transfers (TCS).
- Any foreign assets exceeding R10 million must be declared in the annual tax return (including foreign bank accounts, shares, and property).
Practical tip: Keep a record of all cross-border transactions, including bank statements and exchange rate calculations. SARS may request these during an audit.
6. Common Mistakes South African Business Owners Make
Avoid these pitfalls to stay on the right side of SARS:
- Assuming foreign income is tax-free: Unless you qualify for a specific exemption (like Section 10(1)(o)(ii) for employees), all foreign income is taxable.
- Ignoring foreign exchange gains: If you convert foreign currency back to rands, any exchange rate gain may be taxable as a capital gain or income.
- Not claiming foreign tax credits: Even if the foreign tax is higher than SA tax, you must still declare the income and claim the credit to avoid double taxation.
- Failing to declare foreign assets: SARS now requires disclosure of offshore assets above R10 million. Non-disclosure can lead to penalties of up to 200% of the tax due.

Frequently Asked Questions (FAQ)
1. Do I pay tax on foreign income if I’m not a South African resident?
No. Non-residents are only taxed on South African-sourced income. If you are a non-resident, you do not need to declare foreign income to SARS.
2. What is the foreign income tax rate in South Africa?
Foreign income is taxed at the same progressive rates as local income — from 18% to 45% for individuals, and 27% for companies (effective 2024/2025). The rate depends on your total taxable income.
3. Can I avoid tax by keeping money offshore?
No. South African residents are taxed on worldwide income, regardless of where the money is held. SARS has agreements with many countries to share financial information (CRS).
4. How do I convert foreign currency to rands for tax purposes?
Use the average exchange rate for the tax year (published by SARS) or the spot rate on the day the income was received. Keep a record of the rate used.
5. What happens if I don’t declare foreign income?
SARS can impose penalties of up to 200% of the tax understated, plus interest. In severe cases, criminal prosecution may follow.
