How do tax-free savings accounts work?

Please note: The tax-free savings account limits discussed in Everything Counts episode 42 reflect the regulations in place at the time of recording. Following changes announced in the Budget Speech on 25 February 2026, the annual contribution limit has been increased from R36 000 to R46 000 per tax year, effective 1 March 2026. This article has been updated to reflect new limit.

What is the tax-free savings account limit?

• Annual contribution limit:  From 1 March 2026, you can invest up to R46 000 per tax year into tax-free savings accounts (previously, the limit was R36 000 per tax year).
• Lifetime contribution limit: Over your lifetime, you can invest a total of R500 000 into tax-free savings accounts.

How do tax free savings accounts work?

A tax-free savings account (TFSA) is a government-approved investment account that allows South Africans to earn interest, dividends and capital gains without paying tax on that growth.

They have been available to South Africans for more than a decade, yet many people are still unsure how they work and where they fit into a long-term financial plan. They’re often spoken about in the same breath as savings accounts or unit trusts, but they are fundamentally different in purpose and design.

In a recent episode of Everything Counts, Motheo Khoaripe is joined by Investec financial adviser Vumi Dludlu and Johan Loubser, head of adviser enablement at Investec, to unpack what tax-free savings accounts are, why they were introduced, and how to use them effectively.

Why tax-free savings accounts were introduced

Tax-free savings accounts (TFSAs) were introduced in March 2015 to encourage household savings in South Africa. For many years, South Africa has struggled with a poor savings culture. Policymakers recognised the need for an incentive that would motivate individuals to put money aside for the long term.

That incentive is simple but powerful: no tax on growth.

Within a TFSA, you do not pay tax on interest, dividends or capital gains. In contrast, a regular savings account may attract tax on interest earned above certain thresholds, and other investment vehicles may trigger capital gains tax or dividend withholding tax. The absence of these taxes makes a TFSA a highly efficient long-term wealth-building tool.

However, it’s important to understand that “tax-free” does not mean “risk-free,” nor does it mean “short-term.” The benefit is maximised when the investment is left to grow over time.

Tax free-savings vs regular savings accounts

A TFSA is not just another savings account.

While a TFSA can hold different types of investments, from cash and fixed deposits to unit trusts and exchange-traded funds (ETFs), its real value lies in long-term compounding. The longer the money remains invested, the greater the benefit of tax-free growth.

Because of this, it is generally not suitable as an emergency fund. Emergency savings should be easily accessible and separate from long-term investments. Withdrawing from a TFSA may be allowed, but it comes with an important consequence: you cannot replace withdrawn contributions.

How do tax-free savings accounts work?

The rules governing tax-free savings accounts are straightforward but strict.

From 1 March 2026, you may contribute up to R46 000 per tax year (not calendar year), with a lifetime contribution limit of R500 000. These limits apply per individual, not per account. You can have multiple tax-free savings accounts across different providers, but your combined annual contributions may not exceed R46 000.

The R500 000 cap applies only to contributions, not to growth. If your investments perform well and the value grows beyond R500 000, that’s perfectly acceptable. The limit restricts how much you can put in, not how much it can grow to.

However, if you withdraw money, that portion of your lifetime allowance is permanently reduced. For example, if you contribute R46 000 in a tax year and then withdraw R16 000, you cannot re-contribute that R16 000 in the same tax year. Similarly, unused contribution room does not carry over to the next tax year. If you only contribute R40 000 this year, you cannot contribute R52 000 in the next tax year to “catch up”.

This is why planning and consistency are so important.

The power of opening a tax-free savings account early

Time is one of the most powerful drivers of investment growth. The earlier you start, the greater the impact of compounding.

Even if R46 000 per year sounds daunting, breaking it down makes it more manageable. R46 000 per year equates to around R3 833 per month or roughly R127 per day. Setting up an automated monthly debit order can help ensure you consistently maximise your annual allowance without scrambling at the end of the tax year.

For those who find themselves close to the end of the tax year (which runs from 1 March to the end of February), making a lump sum contribution before the deadline can allow you to use that year’s allowance fully. From there, you can begin the new tax year with a fresh R46 000 limit.

Where does a TFSA fit in your portfolio?

A tax-free savings account should form part of a broader, well-structured financial plan.

Emergency funds typically sit in accessible savings products. Retirement annuities and pension funds are designed specifically for retirement and offer upfront tax deductions on contributions but come with restrictions on access.

TFSAs differ in that they do not reduce your taxable income today, but they eliminate tax on future growth. They also offer flexibility: you have full access to the funds both before and after retirement, although the intention should be to preserve the investment for long-term goals.

Used strategically, a TFSA can complement retirement savings by providing tax-efficient income or liquidity later in life.

Avoiding common mistakes around tax-free savings accounts

Several misconceptions persist around tax-free savings accounts. Some believe they can be used freely as emergency funds without consequence. Others assume they can exceed contribution limits without penalty.

In reality, over-contributions may attract tax penalties, and withdrawals reduce your lifetime allowance. Transferring between providers is allowed, but it must be done as a formal transfer rather than a withdrawal and reinvestment, to avoid affecting your contribution record.

Ultimately, the key to making the most of a tax-free savings account lies in understanding the rules, starting as early as possible, and remaining disciplined.

Tax-free savings accounts are not a shortcut to wealth, but when used correctly and consistently, they are one of the most effective long-term wealth-building tools available to South Africans.
