A Tax-Free Savings Account does exactly what the name says: no income tax, no dividends tax, no capital gains tax on anything it earns, and no tax on withdrawals either. The part that catches people out is not the tax benefit — it is how the contribution limit actually behaves, in ways that are not obvious from how these accounts are marketed as flexible and easy to access.
What actually makes it "tax-free"
Inside a TFSA, interest, dividends and capital gains all accumulate without any tax deducted, and you can withdraw the money tax-free too. That is a genuinely different structure from an ordinary savings account, where interest above your annual exemption is taxable. Real products vary in how they deliver this: our own catalogue includes a flexible, instant-access savings account and a locked 12-month fixed deposit from the same bank (Absa), plus similar products from FNB and Capitec — see the comparison below.
The limits: R46,000 a year, R500,000 for life — per person, not per account
As of 1 March 2026, you can contribute up to R46,000 per tax year across all your TFSAs combined (up from R36,000 previously), with a R500,000 lifetime limit. Both figures are confirmed directly on SARS's own site. Critically, these limits apply to you as a person, not to any single account — opening a second or third TFSA does not give you a second allowance.
Mistake #1: multiple banks, one combined limit nobody is watching for you
You are allowed to hold TFSAs at more than one provider, and plenty of people do — spreading money between a flexible savings account and a fixed deposit, for instance. Each provider reports your contributions to SARS on an IT3(s) certificate, but critically, no single provider can see what you have contributed at a different bank while you are making the deposit. Nothing stops you, in the moment, from putting R30,000 into a TFSA at one bank and another R30,000 into a TFSA at a different bank in the same tax year — R14,000 over the R46,000 limit — until SARS reconciles the certificates at tax time and the 40% penalty applies to the excess. If you hold more than one TFSA, tracking your own combined total across all of them is entirely on you.
Mistake #2: withdrawing does not give you your allowance back
This is the one that catches out people who treat a TFSA like a normal flexible savings account. If you contribute R46,000 in a tax year and then withdraw R10,000 of it, you have not freed up R10,000 of allowance to use again — your usage for the year stays at R46,000, and putting that R10,000 back in counts as a brand new contribution against whatever room you have left (in this example, none, for the rest of that tax year). Products that emphasise "immediate access" or "withdraw anytime" — like the flexible Absa Tax-Free Savings Account in our catalogue — do not warn you about this in the marketing copy, but the SARS rule applies regardless of how easy the provider makes it to take money out.
Cash TFSA vs. investment TFSA — we only cover one of these
The products in our deposits category are cash-based: a savings account or a fixed deposit paying interest. Several banks also offer a market-linked "tax-free investment account" built on unit trusts or ETFs, which carries investment risk and a different return profile entirely — that is a distinct product category we do not compare here. If you are choosing between a cash TFSA and an investment-linked one, that is a different decision than choosing between two savings accounts, and worth treating as such.
Real products compared
All four products below share the same R46,000/R500,000 SARS limits — what differs is access and structure:
- Absa Tax-Free Savings Account: R1,000 minimum, immediate access, no monthly fee — rate not published on the product page.
- Absa Tax-Free Fixed Deposit: R30,000–R36,000 once-off, locked for 12 months, up to 7.6% — no access until maturity.
- FNB Tax-Free Cash Deposit: from R300, 100% capital guarantee, up to 7.2% at R1,000,000+ — but a 32-day notice period to access funds, not instant.
- Capitec Tax-Free Savings Account: no monthly fees, but a R300 fee applies if you access funds early, before the account's agreed capitalisation date.
Frequently asked questions
If I have TFSAs at two different banks, will one of them stop me from going over the limit?
No. Each provider only sees your activity with them — neither can see what you have contributed elsewhere in real time. Tracking your combined total across every TFSA you hold is your own responsibility.
I withdrew money from my TFSA — can I just put it back?
Not for free. Redepositing it counts as a new contribution against whatever annual or lifetime allowance you have left; it does not restore the amount you withdrew.
What actually happens if I go over the limit?
SARS applies a 40% tax on the amount that exceeds either the annual limit or the lifetime limit, whichever applies.

Separately from the tax treatment, your TFSA balance is also protected up to R100,000 per bank under the same deposit insurance scheme that covers ordinary savings accounts.
