South Africa Cross-Border Tax Guide

Tax Residency Tests

An individual is considered ordinarily resident in South Africa if South Africa is their natural home — the country to which they return after periods of travel or work abroad. The test is qualitative, considering factors such as physical presence, family ties, property ownership, and economic connections. If an individual is not ordinarily resident, the physical presence test applies: 91 days in the current tax year, 183 days in total over the current and five prior years, and 183 days physically present in South Africa during the current tax year.

Non-residents are taxed only on South African-source income, including income from services rendered in South Africa, dividends from South African companies, rental income from South African property, and capital gains from the disposal of immovable property in South Africa. Interest income for non-residents is generally exempt from South African tax if the beneficial owner is a non-resident, subject to certain conditions.

Foreign Employment Income Exemption (Section 10(1)(o)(ii))

South African residents working outside the country may qualify for an exemption on foreign employment income if they spend at least 183 days outside South Africa in a 12-month period, with at least 60 consecutive days outside South Africa during that period. For 2026, the first ZAR 1.25 million of foreign employment income is exempt from South African tax under this provision. Amounts exceeding ZAR 1.25 million are fully taxable in South Africa at marginal rates (18–45%).

This exemption applies only to employment income (salary, wages, bonuses) and not to other foreign income such as investment income, rental income, or business profits. Taxpayers claiming the exemption must be able to demonstrate their physical presence outside South Africa for the required period, typically through travel records, passport stamps, and employer letters. The exemption is claimed as part of the annual ITR12 tax return filing.

Foreign Tax Credit (Section 6quat)

When foreign-source income is taxable in both South Africa and another jurisdiction, section 6quat of the Income Tax Act provides a rebate for foreign taxes paid. The credit is limited to the lower of the foreign tax actually paid and the South African tax attributable to that foreign income. This prevents double taxation while ensuring that South Africa's right to tax is not exceeded by the credit. The credit is claimed on the ITR12 return and must be supported by proof of foreign tax paid.

The section 6quat rebate is only available for foreign taxes that are similar to South African income tax. It does not apply to foreign withholding taxes on dividends, interest, or royalties — these may be creditable under different provisions or DTAs. For capital gains, the foreign tax credit is calculated separately on the inclusion rate portion of the gain (40% inclusion for individuals). Taxpayers who cannot claim the full credit may be able to deduct the excess foreign tax as an expense.

Double Taxation Agreement (DTA) Network

South Africa has concluded DTAs with over 80 countries, including all major trading partners such as the United Kingdom, United States, Germany, China, India, Australia, and other African nations. These agreements allocate taxing rights between South Africa and the treaty partner, typically following the OECD Model Tax Convention. DTAs may override domestic law and can provide reduced withholding tax rates on dividends, interest, and royalties paid to residents of treaty countries.

Under most DTAs, employment income is taxable in the country where the employment is physically exercised. If an individual works in another treaty country for less than 183 days in a 12-month period and the employer is a South African resident (and the salary is borne by the South African employer), the employment income remains taxable only in South Africa. This is commonly known as the 183-day DTA exemption and is frequently relied upon by cross-border workers. Taxpayers should review the specific DTA with the relevant country, as provisions vary.
