A practical checklist of the filing mistakes South Africans abroad should avoid before submitting a SARS return.
Last updated: 20 May 2026
- Do not treat being overseas as proof that no South African return is needed.
- Residency, source of income, foreign tax paid, and SARS profile status must be checked separately.
- Keep travel, employment, foreign tax, and South African income records in one audit file.
Mistakes to avoid
- Assuming foreign salary is always tax-free in South Africa.
- Claiming the foreign employment exemption without proving the day-count and employment requirements.
- Ignoring South African rental, retirement, investment, or capital gains information.
- Using a treaty position without keeping foreign tax-residence proof.
- Missing SARS notices because contact details or OTP details are outdated.
Prevention checklist
- Build a travel calendar before filing.
- Separate South African-source and foreign-source income.
- Keep foreign payslips, assessments, and tax certificates.
- Check eFiling pre-populated data against your own records.
- Get help before changing tax residency or claiming treaty relief.
Records to keep
- Travel dates, passport pages, visas, leases, and employment contracts.
- South African and foreign tax returns, assessments, certificates, and proof of tax paid.
- Bank, investment, property, retirement, medical, and SARS eFiling records that support the return.
- A note explaining the tax year, residency position, income source, exchange rate, and SARS source checked.
