AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
SARS's tax-free investment rules do not exclude foreign nationals; whether you can open one depends on the provider's own account-opening checks. From 1 March 2026 you can put in up to R46,000 a tax year and R500,000 over your lifetime, and SARS adds 40% of any excess as tax. The returns are free of income tax and capital gains tax in South Africa.
What SARS says about who qualifies
SARS's Tax Free Investments page (updated 20 March 2026) sets the limits and lists who may offer the accounts: licensed banks, long-term insurers, registered collective investment scheme managers and certain others. It says parents can invest for a minor child, who uses their own limits. It says nothing about citizenship, residence permits or nationality. So the question is not whether SARS allows you, but whether the bank or fund house will onboard you.
Providers apply their own customer checks. Ask in advance which documents they accept from permit holders, such as a passport, a valid visa or permit and proof of address, and whether they need a SARS tax reference number. If you do not have one, see getting a SARS tax number as a foreign national.
The limits
| Tax year | Annual limit |
|---|---|
| 2016 to 2017 | R30,000 |
| 2018 to 2020 | R33,000 |
| 2021 to 2026 | R36,000 |
| 2027 onward (from 1 March 2026) | R46,000 |
- Lifetime limit
- R500,000 per person
- Unused annual limit
- Forfeited; it does not carry forward
- Penalty on excess
- 40% of the excess, added to your tax
- Withdrawals
- Do not restore the limit; money withdrawn and put back counts as a new contribution
SARS's own example
A R50,000 contribution in the 2027 tax year is R4,000 over the R46,000 limit; 40% of R4,000 is a R1,600 penalty. At the full R46,000 a year, the R500,000 lifetime limit is reached in just under 11 years (R500,000 divided by R46,000 is about 10.9).
What you can hold in one
SARS lists fixed deposits, unit trusts, certain long-term insurer endowment policies, linked investment products and exchange traded funds classified as collective investment schemes. Since 1 March 2018 you can transfer between tax-free accounts at different providers. A transfer is not a withdrawal, so use the transfer process if you change provider rather than closing one account and opening another.
Mistakes that trigger the penalty
Most TFSA penalties come from honest errors, not from trying to beat the system.
- Opening a second TFSA at another bank and forgetting that both count towards one R46,000 limit.
- Withdrawing in an emergency and topping the account back up later in the same year: the top-up is a new contribution.
- Moving money between providers by withdrawing and reinvesting instead of using a formal transfer.
- A parent opening an account for a child and then the child, as an adult, opening another and contributing the full amount.
- A debit order that keeps running after the year's limit is reached.
Keep your own running total across all accounts, by tax year, from 1 March to the end of February, and check it against each provider's annual statement. If you find an excess, ask a tax practitioner how SARS will assess it before you file.
Is it worth it if you might leave?
The benefit is South African: no income tax, dividends tax or capital gains tax on the returns in South Africa (Budget 2026 Tax Guide). If you later move back to Nigeria, the account does not move with you, and Nigeria's tax rules, not SARS's, decide how the returns are treated once you are resident there. Cashing it in before you leave uses up the contributions you made, which cannot be replaced.
- Short stay, a year or two: a TFSA's advantage is small and the R46,000 annual cap limits it anyway.
- Long stay or permanent residence: using the annual limit each year builds a meaningful tax-free pot.
- Unsure: a TFSA unit trust can be held for years, so contributing now keeps the option open.
Compare it with the interest exemption: the Budget 2026 Tax Guide exempts up to R23,800 a year of South African-source interest for people under 65, so a small savings balance may already be tax-free without a TFSA. A TFSA wins once your interest would exceed that, or for growth assets where dividends and capital gains matter. This is information, not advice.
Steps to open one
- Get your SARS tax reference number.
- Choose the product type: a bank deposit for certainty, or a unit trust or ETF for growth.
- Ask the provider whether it onboards holders of your permit or visa, and which documents it needs.
- Open the account and set a debit order that keeps you under R46,000 a tax year.
- If you hold more than one TFSA, add up the contributions yourself; the limit is per person, across all providers.
Where Pryme fits
A TFSA is a rand product; Pryme does not offer one. If you also save in naira for goals at home, Savings Boxes are for naira held in Nigeria, with rates shown in the app (Savings Boxes). Before choosing where to save, see saving in naira or rand: an inflation example. Your Personal Assistant can remind you of the 28 February tax year end (Personal Assistant).
Questions people ask
Can I open a TFSA with a passport in South Africa?
SARS's rules do not exclude foreign nationals. Whether a passport is accepted depends on the provider's onboarding checks, so ask the bank or fund house first.
What is the tax-free savings limit for 2026/27?
R46,000 a tax year from 1 March 2026, and R500,000 over your lifetime, according to SARS.
What happens if I put in too much?
SARS adds 40% of the excess to your tax. Putting in R50,000 in the 2027 tax year means a R1,600 penalty on the R4,000 excess.
Can I withdraw and put the money back later?
You can withdraw, but money put back counts as a new contribution against both the annual and lifetime limits.
