Tax-free savings accounts (TFSA) explained
A TFSA is one of the most valuable tools available to South African investors. Used well over many years, it can save you a meaningful amount in tax. Here's how it works.
What is a TFSA?
A tax-free savings account is a special investment account introduced by the South African government to encourage saving. Everything that grows inside it — interest, dividends and capital gains — is completely free of tax. Normally you'd pay tax on those returns; inside a TFSA, you don't.
Contribution limits
The tax break comes with limits set by SARS:
- Annual limit: R36,000 per tax year (at the time of writing).
- Lifetime limit: R500,000 in total contributions (at the time of writing).
These figures can change, so always confirm the current limits before contributing. Importantly, the limits apply across all your TFSAs combined, not per account.
What can you hold in a TFSA?
Depending on the provider, a TFSA can hold cash, ETFs, unit trusts and other approved investments. Because growth is tax-free, many long-term investors use their TFSA to hold growth assets like equity ETFs, where the tax saving on decades of compounding can be substantial.
The power of tax-free compounding
The real magic is time. When returns compound year after year without tax dragging them down, the difference versus a taxable account grows wider the longer you stay invested. That's why financial educators often suggest maximising your TFSA early and holding for the long term.
Common mistakes to avoid
- Over-contributing — the penalty is 40% of the excess. Track every contribution.
- Using it as a bank account — frequent withdrawals waste precious lifetime room.
- Holding only cash — for long horizons, growth assets often make better use of the tax shelter (though this depends on your goals and risk tolerance).
A TFSA works best as one part of a broader plan. Learn how to build a diversified portfolio to see where it fits.
