The real difference is when you pay the tax
A tax-free savings account (TFSA) and a retirement annuity (RA) are both genuinely tax-smart, but they hand you the tax break at opposite ends. Money going into a TFSA has already been taxed. In return, nothing it earns is ever taxed again: no income tax on interest, no dividends tax, no capital gains tax, and nothing when you take it out. Money going into an RA has not been taxed yet, because your contribution comes off your taxable income this year. The growth inside is also untaxed, but what you draw in retirement is taxed.
So the TFSA is tax-free at the end, and the RA is tax-free at the start. Which end is worth more depends on your tax bracket today and on how long you can live without the money. The second question matters more than it used to, because the two-pot system changed what "locked away" means.
The rules for 2026/27
For the TFSA, from 1 March 2026:
- You can contribute R46,000 per tax year, up from R36,000, and R500,000 over your lifetime. Anything above either limit is hit with a 40% penalty on the excess, and the limits apply across all your TFSAs combined.
- Unused annual room is forfeited, not carried forward.
- Withdrawals do not give the room back. Money you put back in counts as a new contribution. Growth that stays inside does not use up room, only the money you add does.
- Only certain products qualify, such as unit trusts, fixed deposits and ETFs that are classified as collective investment schemes. Our beginner's guide to ETFs covers what is and is not allowed.
For the RA:
- Your deduction is the lesser of 27.5% of the greater of your remuneration or taxable income and a rand cap, which is R430,000 for the tax year that began on 1 March 2026 (it was R350,000 the year before). The 27.5% is combined across every retirement fund you have, and an employer's contributions count toward it.
- Only very high earners ever meet the rand cap: 27.5% reaches R430,000 at roughly R1.56 million of income. For everyone else the percentage is the limit.
- Contributions above the limit are not lost. They carry forward to later years, and anything still unused when you retire can be set against tax on your lump sum or annuity.
- At retirement you can take part of the fund as cash and must use the rest to buy an annuity, unless the pot is small enough to take in full (that threshold rose to R360,000 on 1 March 2026). The first R550,000 of retirement lump sums over your lifetime is taxed at 0%. Annuity income is taxed at your marginal rate.
What the RA deduction is actually worth
The deduction is only worth your marginal rate, so it varies enormously. Take someone contributing R3,000 a month, or R36,000 a year, using the 2026/27 tax tables:
- Taxable income of R200,000 (18% bracket): the deduction saves R6,480, so the contribution really costs R29,520.
- Taxable income of R300,000 (26% bracket): it saves R9,360.
- Taxable income of R500,000 (31% bracket): it saves R11,160.
- Taxable income of R800,000 (39% bracket): it saves R14,040, so R36,000 really costs R21,960.
If your taxable income is under the R99,000 tax threshold, the deduction is worth nothing, because there is no tax to reduce. That is the one group for whom a TFSA is clearly the better first stop. The saving usually arrives when SARS assesses your return, as a lower bill or a refund, not on the day you contribute.
An RA is no longer fully locked
Since 1 September 2024, new RA contributions are split: one third goes into a savings component, and two thirds into a retirement component you cannot touch before retirement. You can make one withdrawal from the savings component per tax year, with a minimum of R2,000, and it is taxed at your marginal rate. Only the pre-September 2024 balance stays locked until age 55. Our guide to RAs, pension and provident funds has the full access rules.
That sounds like flexibility, but look at the arithmetic. Say you are in the 31% bracket and put R10,000 into an RA. The deduction returns R3,100, so it really cost you R6,900. About R3,333 of it lands in the savings component. Withdraw that and SARS takes 31%, leaving R2,300. That is exactly what that slice cost you after the deduction, so you get your money back but the tax benefit is gone, and the slice stops compounding. The same withdrawal from a TFSA is untaxed. The savings component is an emergency exit, not a substitute for liquid savings.
A 25-year comparison
Here is a sum you can check yourself. Assume R10,000 of salary before tax, a 31% bracket, 8% growth a year for 25 years, no fees, and no adjustment for inflation. These are my assumptions for illustration, not a forecast.
- TFSA: after 31% tax you have R6,900 to invest. It grows to about R47,250, all tax-free.
- RA: the full R10,000 is invested. It grows to about R68,500 before tax. Assume one third is taken as a lump sum within the R550,000 tax-free band, and the other two thirds is taxed as annuity income. If your marginal rate in retirement is 18%, you keep about R60,300. At 26% you keep about R56,600. Even at 31%, the same bracket you contributed in, you keep about R54,300.
So on pure tax maths the RA stays ahead, because a third of it escapes tax altogether and people often retire into a lower bracket. The catch is everything the sum ignores: fees vary by product and compound against you in both accounts, and the whole advantage depends on you leaving the money alone for 25 years. Cash out early and the edge shrinks or disappears. That is why the real decision is about access, not tax.
A sensible order for your next rand
- Build a starter buffer in an ordinary savings account. Neither a TFSA nor an RA is an emergency fund. See how to start a buffer fund.
- Clear store card and credit card debt. It costs more than either account can reasonably earn.
- Check what your employer already contributes. It uses up part of your 27.5%, so your RA room may be smaller than you think.
- Then choose by bracket and horizon. If your taxable income is above R383,100 (31% and up) and you will not need the money before retirement, the RA deduction is hard to beat. If you are in the 18% bracket, or the money has a job within ten years, fill the TFSA first.
- Recycle the refund. Put the tax you save from an RA contribution into your TFSA. It is money you would not otherwise have had.
Mistakes that cost real money
- Treating a TFSA like a current account. Withdrawals permanently use up your lifetime room, and at the full R46,000 a year it still takes about eleven years to reach R500,000. Taking money out early costs you room you cannot buy back.
- Locking up money you will need. Contributing beyond what you can comfortably leave until retirement, just to chase the deduction, leaves you with a pot you cannot use and no cash for the years in between.
- Not claiming the deduction. RA contributions made through a provider are among the items an auto-assessment can leave out. Check that the figure on your return matches the IT3(f) certificate your provider issues. If you are still correcting last year's return, our guide to the SARS auto-assessment deadline covers the 23 October 2026 cut-off. Contributions you make now belong to the 2027 tax year.
- Opening a second TFSA without counting the first. The limit is per person, not per provider.
Quick answers
Can I have a TFSA and an RA at the same time?
Yes. They are separate products with separate limits, and for most people the eventual answer is both, funded in a deliberate order.
Which should a freelancer or irregular earner fund first?
Usually the buffer, then the TFSA, since it stays reachable if income dips, and then the RA in the stronger months. The method in irregular income budgeting shows how to size the buffer.
What happens if I put more than R46,000 into my TFSA in a year?
SARS charges a 40% penalty on the excess, added to your tax assessment. Growth inside the account does not count toward the limit, only new contributions do.
Does the R430,000 RA cap apply to the return I am filing now?
No. For the year ended 28 February 2026 the cap was R350,000. The R430,000 figure applies to contributions from 1 March 2026.
Keeping both in view
Budget Hub's investments hub lets you record a TFSA and an RA as holdings, next to your unit trusts and shares, so your retirement money does not disappear from view. Their values come from your provider statements and are updated by hand, and the hub flags a holding once it has gone too long without an update. The free plan holds three investments. One thing it does not do is track how much you have contributed in a tax year, so keep your provider's statements, and the IT3(f) for the RA, for that number.
