Introduction
If you are a South African business owner earning income from outside the country’s borders, you have likely asked yourself: “How does foreign income tax South Africa actually work?” The answer is not always straightforward, but getting it right is critical. SARS (the South African Revenue Service) has become increasingly sophisticated in tracking offshore earnings, and the penalties for non-compliance can be severe.
This guide simplifies the complex landscape of foreign income tax for 2026. Whether you run an export business, work remotely for an overseas client, or own a property abroad, understanding your tax obligations will save you money and stress. At Blu Solutions, we specialise in helping SA business owners navigate these waters from our offices in Mossel Bay, George, Knysna, and Cape Town. Let us break it down for you.
What Is Foreign Income Tax in South Africa?
South Africa taxes its residents on their worldwide income. This means if you are a South African tax resident, any income you earn – whether it is from a job in London, a business in Dubai, or dividends from a US company – is subject to South African income tax. This is known as the residence-based tax system.
However, there are important exemptions and relief mechanisms. The most notable is the foreign employment income exemption (Section 10(1)(o)(ii) of the Income Tax Act), which previously allowed South Africans working abroad to exempt up to R1.25 million of their foreign salary. Note: This exemption was removed for most taxpayers effective 1 March 2025. For the 2026 tax year, the rules have changed significantly.
If you earn foreign income while physically present in South Africa (e.g., remote work for a UK company while living in Cape Town), that income is fully taxable in South Africa from the first rand. There is no automatic exemption.
Key SARS Definitions You Must Know
- Tax Resident: A person who meets the “ordinarily resident” test or the “physical presence” test (more than 91 days in the current year, 91 days in each of the prior 5 years, and 915 days total in the prior 5 years).
- Foreign Income: Income earned from a source outside South Africa, including salaries, business profits, rental income, interest, and dividends.
- Double Taxation Agreement (DTA): An agreement between South Africa and another country to prevent the same income being taxed twice.
How Foreign Income Is Taxed in 2026
For the 2026 tax year (1 March 2025 – 28 February 2026), the rules are clearer but stricter. Here is the breakdown:
1. Foreign Salary Earned While Working Outside SA
If you are a South African tax resident but physically work outside the country for more than 183 days in a 12-month period (with at least 60 continuous days outside SA), you may qualify for the foreign employment income exemption. However, from 1 March 2025, this exemption is capped at R1.25 million per year of assessment. Any foreign salary above R1.25 million is fully taxable in South Africa.
Example: John works in Dubai for 10 months. He earns R2 million. The first R1.25 million is exempt. He pays tax on the remaining R750,000 at marginal rates (up to 45%).
2. Foreign Business Income (e.g., Exporting Services or Products)
If you run a South African registered business that earns income from foreign clients, that income is fully taxable in South Africa. There is no exemption for business income. You must declare it in your tax return and pay tax at the applicable corporate or individual rate.
Tip: You can claim expenses incurred to earn that foreign income (e.g., travel, marketing, software subscriptions). Keep meticulous records.
3. Passive Foreign Income (Dividends, Interest, Rental)
Foreign dividends, interest, and rental income are fully taxable in South Africa. However, you may be able to claim a foreign tax credit if you paid tax on that income in another country. This prevents double taxation.
Example: You own a flat in London. You earn R100,000 in rent and pay R20,000 in UK tax. In your South African return, you declare R100,000 income, but claim a R20,000 foreign tax credit. You only pay SA tax on the net amount.
Practical Steps for SA Business Owners
Here is how to stay compliant and minimise your tax burden:
Step 1: Determine Your Tax Residency Status
Are you a South African tax resident? If you live and work abroad but still have strong ties to SA (e.g., a home, family, bank accounts), SARS may still consider you a resident. Pro tip: Keep a log of days spent in and out of SA. Use the physical presence test to confirm your status.
Step 2: Register with SARS for Foreign Income
If you earn foreign income, you must register as a taxpayer (if not already) and declare it in your annual return (ITR12). SARS now requires detailed disclosures of foreign assets and income. Use the Foreign Income and Assets Declaration section.
Step 3: Claim All Available Deductions
You can deduct expenses directly related to earning foreign income. For example:
- Travel costs to meet foreign clients
- Bank fees on foreign currency accounts
- Professional fees (accountants, lawyers) for tax compliance
- Exchange rate losses (if you convert foreign income to ZAR)
Step 4: Understand Double Taxation Agreements (DTAs)
South Africa has DTAs with over 70 countries. If you pay tax in a treaty country, you can often claim relief. For example, if you pay 10% tax in the UK on interest, you can credit that against your SA tax liability. Our team at Blu Solutions can help you interpret the specific DTA applicable to your situation.
Common Mistakes SA Business Owners Make
Avoid these pitfalls when dealing with foreign income tax in South Africa:
- Assuming foreign income is tax-free: Unless you qualify for the specific exemption (and it’s capped at R1.25 million), all foreign income is taxable.
- Not declaring foreign bank accounts: SARS requires you to disclose foreign accounts and assets if the total value exceeds R300,000 (or if you earned foreign interest/dividends).
- Ignoring exchange rate fluctuations: SARS requires you to convert foreign income to ZAR using the average exchange rate or the spot rate on the day of receipt. Inconsistent conversions can trigger audits.
- Failing to keep records: Keep contracts, invoices, bank statements, and tax receipts for at least 5 years. SARS can request them at any time.

Frequently Asked Questions (FAQ)
Do I need to pay foreign income tax in South Africa if I live abroad?
If you are a South African tax resident (e.g., you have a home in SA and plan to return), you must declare and pay tax on your worldwide income. If you have formally emigrated and are no longer a resident, you only pay tax on SA-sourced income.
What is the foreign income exemption for 2026?
For the 2026 tax year, the foreign employment income exemption is R1.25 million. It applies only to salary earned while physically outside South Africa for at least 183 days in a 12-month period (with 60 continuous days abroad). Business income and passive income do not qualify.
Can I deduct expenses against foreign income?
Yes. You can deduct expenses directly incurred to earn foreign income, such as travel, accommodation, bank charges, and professional fees. Keep all receipts and records.
What happens if I don’t declare foreign income?
SARS can impose penalties of up to 200% of the tax due, plus interest. In serious cases, criminal prosecution is possible. Voluntary disclosure may reduce penalties – speak to a tax professional immediately.
How do I convert foreign income to Rands for SARS?
Use the average exchange rate for the tax year (published by SARS) or the spot rate on the date you received the income. Be consistent. We recommend using the average rate for simplicity.
