Frequently asked questions
How does a Tax-Free Savings Account (TFSA) work in South Africa?
Under SARS regulations, South Africans can invest up to R36,000 per tax year and R500,000 lifetime into approved TFSA funds without paying local dividends tax, income tax on interest, or capital gains tax.
What is a realistic investment return rate in South Africa?
Long-term historical annualized returns on the JSE All Share Index (ALSI) average around 10%–12% before inflation, balanced unit trust funds average 8%–10%, and cash/fixed income yields 7%–9%.
How does inflation impact South African investments?
With SARB target inflation between 3% and 6% (averaging ~4.5%–5%), your real return is nominal return minus inflation. Achieving at least CPI+4% preserves long-term purchasing power.
What happens if I exceed the R36,000 annual TFSA limit?
SARS levies a 40% penalty tax on any contribution exceeding the annual R36,000 limit or lifetime R500,000 threshold.
