South Africans living abroad may still have SARS filing duties, South African-source income issues, or residency questions. This guide explains the checks to make before assuming you are outside the South African tax net.

- Start with tax residency and source of income, not citizenship alone.
- Keep travel, employment, foreign tax, and South African income records together.
- Use treaty rules carefully because each country agreement can differ.
Start with tax residency, not citizenship
South African tax for expatriates depends mainly on tax residency and source of income. Citizenship, a South African passport, or the fact that you live abroad does not automatically decide the tax answer.
A South African tax resident is generally taxed on worldwide income, subject to exemptions, credits, and treaty relief. A non-resident may still be taxed in South Africa on South African-source income, such as rental income from South African property or income for services performed in South Africa.
Questions expatriates should answer first
- Are you still ordinarily resident in South Africa?
- Do you meet the physical presence test?
- Have you formally declared a change in tax residency to SARS, if required?
- Do you earn South African-source income while abroad?
- Have you paid foreign tax on the same income?
- Does a double taxation agreement apply to your facts?
Foreign employment income
Foreign salary is not automatically tax-free for South Africans abroad. The answer depends on residency status, where services are rendered, the foreign employment income exemption, any foreign tax paid, and the wording of the relevant treaty.
If your foreign income is above the exemption limits or does not meet the exemption conditions, you may need to consider South African tax, foreign tax credits, and supporting records.
Common expatriate mistakes
- Assuming emigration, a visa, or a foreign job automatically ends South African tax residency.
- Ignoring South African rental income, investment income, or business interests after moving abroad.
- Failing to keep travel calendars, employment contracts, payslips, foreign tax assessments, and proof of days outside South Africa.
- Relying on a treaty without checking the exact country agreement and tie-breaker article.
FAQ
Do South African expatriates still file tax returns?
Possibly. Filing depends on SARS requirements, residency status, income type, and whether SARS has requested a return.
Does living abroad make me a non-resident?
Not by itself. SARS looks at ordinary residence, physical presence, and treaty position based on the facts.
Can foreign tax reduce South African tax?
It may, depending on the income, treaty position, and foreign tax credit rules. Keep proof of foreign tax paid.
Next steps
- Prepare a timeline of where you lived and worked during the tax year.
- Separate South African-source and foreign-source income before filing.
- Check whether SARS or a foreign tax authority needs a residency certificate or supporting proof.
