TFSA: no tax on interest, dividends, or capital gains. Taxable: interest taxed at 36% after R23,800 annual interest exemption. Lifetime TFSA limit: R500,000. Annual limit: R36,000. Excess contributions attract 40% penalty.
Using a Tax-Free Savings Account to Save for Property TFSA basics • Limits • Strategy
What is a Tax-Free Savings Account (TFSA)?
South Africa's Tax-Free Savings Account (TFSA), governed by Section 12T of the Income Tax Act, was introduced in March 2015. It allows South Africans to save and invest without paying any tax on interest, dividends, or capital gains earned within the account.
- Annual contribution limit: R36,000 per person per tax year (R3,000/month)
- Lifetime contribution limit: R500,000 per person
- Excess contributions: Penalised at 40% tax on the excess amount
- No tax on growth: Interest, dividends, and capital gains within the TFSA are completely exempt from tax
- Withdrawals: Allowed at any time, but withdrawn amounts do not restore your contribution limit
A key point: if you withdraw from your TFSA, the contribution room is permanently lost. You cannot re-contribute the amount you withdrew. This makes TFSA savings best treated as long-term, purpose-driven savings.
TFSA vs Taxable Savings Account
Taxable: Effective Rate = Gross Rate × (1 − Marginal Tax Rate)
Tax Saved per Year = Interest Earned × Marginal Rate (above R23,800 exemption)
Lifetime TFSA Advantage = Cumulative Tax Saved + Compounded Growth Differential
Worked Example — Nomsa Saving for a Deposit
Nomsa wants to save R300,000 for a property deposit. She contributes R3,000/month into a TFSA earning 9% per annum. She is in the 36% marginal tax bracket.
In a TFSA: At 9% gross, Nomsa reaches R300,000 after approximately 68 months (5.7 years).
In a taxable savings account: Her effective after-tax rate is approximately 9% × (1 − 36%) = 5.76%. She would reach R300,000 after approximately 78 months (6.5 years) — nearly a year longer.
Over 10 years at R3,000/month (reaching the R360,000 contribution cap), her TFSA balance would be approximately R559,000 versus R510,000 in a taxable account — a R49,000 advantage from the TFSA structure, plus she pays no tax on withdrawals.
Frequently Asked Questions
What is the TFSA annual and lifetime limit in South Africa for 2026?
The annual contribution limit is R36,000 per person (R3,000 per month), and the lifetime limit is R500,000 per person. These limits have remained unchanged since 2015. Contributions exceeding R36,000 in any tax year attract a 40% penalty tax levied by SARS on the excess amount. Your spouse has their own separate limits.
Can I use my TFSA for a property deposit in South Africa?
Yes. There are no restrictions on what you use TFSA proceeds for. You can withdraw your full TFSA balance at any time to use as a property deposit — with no tax payable on the withdrawal. The caveat is that once you withdraw, you lose that contribution room permanently. You cannot re-contribute the withdrawn amount (unlike a retirement annuity).
What happens if I contribute more than R36,000 per year to my TFSA?
SARS will levy a 40% tax on any contributions exceeding R36,000 in a tax year. This penalty is included in your annual tax assessment. Your financial institution is required to report all TFSA contributions to SARS, so excess contributions are automatically detected. Always monitor your total annual contributions if you have multiple TFSA accounts across different institutions.
Is a TFSA or a retirement annuity (RA) better for saving for property?
For a property deposit, a TFSA is better because withdrawals are flexible and penalty-free, with no tax payable. A Retirement Annuity (RA) gives you a bigger upfront tax deduction (contributions are deductible), but you cannot access the money before age 55, and only 1/3 is available as a lump sum at retirement — the rest must purchase an annuity. Use the RA for long-term retirement savings and the TFSA for medium-term goals like a property deposit.
Which SA banks and platforms offer Tax-Free Savings Accounts?
Major TFSA providers in South Africa include: FNB (tax-free cash deposit and ETF options), Nedbank (JustSave and investment options), Absa (savings and investment TFSAs), Standard Bank (MySavings and investment), Capitec (flexible and fixed deposits), and investment platforms such as Allan Gray, Coronation, Sanlam, Discovery, and Easy Equities (ETF-based TFSAs with potential for higher returns).
