Quick Answer

SARS requires you to keep all tax-related documents for at least 5 years from the date of assessment.

Residency Status

If you are a South African tax resident, you must declare all foreign income including salary, dividends, interest, and rental income from abroad.

Double Taxation Relief

South Africa has double taxation agreements with many countries. You can claim foreign tax credits for tax paid overseas to avoid being taxed twice on the same income.

Documentation Needed

Gather foreign employment contracts, payslips, foreign tax returns, proof of foreign tax paid, and bank statements showing foreign income deposits.
