RA Contribution Limits 2026: The 27.5% and R350k Rules Explained

The rule in one line, and why it pays you back

A retirement annuity (RA) lets you deduct contributions from your taxable income, which means SARS effectively refunds part of what you put in. The 2026 rule: you can deduct up to 27.5% of the greater of your remuneration or your taxable income, with a hard ceiling of R350,000 per tax year. Whichever of those two income figures is larger is the base you multiply by 27.5%, and the answer is capped at R350,000.

The deduction is not a flat rebate handed to everyone — it is worth your marginal tax rate. If your top slice of income is taxed at 36%, every rand you deduct via an RA gives you 36 cents back. At 41%, it is 41 cents. That is the entire mechanism: you move money from taxable income into a retirement product, your taxable income falls, and SARS recalculates your tax on the lower figure. The gap between the two is your refund.

This is why RAs are the most efficient voluntary deduction available to a salaried South African. A R36,000 TFSA contribution grows tax-free but gives you nothing back today. A R36,000 RA contribution at a 41% marginal rate puts R14,760 back in your pocket this year and still grows in a tax-sheltered fund. The trade-off is access: RA money is locked until age 55, whereas a TFSA can be withdrawn (you just lose the room). This is general information, not personalised advice.

Employer pension and provident contributions count toward the same 27.5%

The single most misunderstood point: the 27.5% / R350,000 limit is a combined limit across all your retirement funds. If you are a member of a workplace pension or provident fund, the contributions made to that fund — both yours and your employer's — already use up part of your 27.5% allowance. Your private RA only gets the room that is left over.

Worked through: say you earn R600,000 and your employer fund takes 15% of pensionable pay between you and them. That is roughly R90,000 already deducted through payroll. Your 27.5% ceiling on R600,000 is R165,000. Subtract the R90,000 already used, and you have about R75,000 of headroom left for a private RA before you hit the cap. Contribute more than R75,000 into the RA and the excess is not wasted, but it is not deductible this year either.

Note the wrinkle on the employer's share: the amount your employer contributes to a pension or provident fund on your behalf is added to your taxable income as a fringe benefit, and then the same amount is allowed as a deduction. The net effect is neutral for the employer portion, but it still consumes your 27.5% room. So before you decide how much to pour into a private RA, get your retirement-fund contribution figure off your payslip or IRP5 — that number determines your real headroom.

Worked example: R600,000 income

Assume an under-65 taxpayer earning R600,000 in taxable income, no workplace fund, contributing the maximum to a private RA. Their 27.5% ceiling is 0.275 × R600,000 = R165,000, comfortably under the R350,000 cap. So they can deduct the full R165,000.

Now the refund. At R600,000, this person sits in the 36% bracket (the band from R512,801 to R673,000). But the R165,000 deduction is large enough to drag their taxable income down past a bracket line, to R435,000 — which lands in the 31% band. So the refund is blended, not a flat 36%. The top R87,200 of the deduction (the slice that was sitting above R512,800) is refunded at 36% = R31,392. The remaining R77,800 falls in the 31% band and refunds at 31% = R24,118.

Total tax refund: R55,510 on a R165,000 contribution — an effective 33.6% back. Put differently, R165,000 of retirement saving cost this person only R109,490 out of pocket after the refund. The lesson: when a big contribution crosses a bracket boundary, your average refund rate is lower than your headline marginal rate, because the lower slices of the deduction only save tax at the lower band.

Worked example: R1.2 million income

Now a taxpayer on R1,200,000 of taxable income. Their 27.5% ceiling is 0.275 × R1,200,000 = R330,000 — still below the R350,000 cap, so the cap does not bite yet. They can deduct R330,000.

This person's marginal rate is 41% (the band from R857,901 to R1,817,000). The R330,000 deduction lowers taxable income from R1,200,000 to R870,000 — and both of those figures sit inside the same 41% band, which runs from R857,901 to R1,817,000. R870,000 is above the R857,900 line, so it never drops into the 39% band below. Because the entire deduction stays within one bracket, the refund is a clean 41%: R330,000 × 41% = R135,300.

So R330,000 of retirement saving costs R194,700 after a R135,300 refund. Compare the two examples honestly: the R1.2m earner gets a higher refund rate (41% vs a blended 33.6%) because their income never drops out of the top band they are saving from. Higher earners extract more value per rand from an RA — which is exactly why the cap exists.

The R350,000 cap and what carries forward

The R350,000 ceiling only starts to bite once your income exceeds about R1,272,727 (because 27.5% of that figure is R350,000). Below that, the 27.5% rule is your binding constraint; above it, the flat R350,000 is. Someone earning R2,000,000 cannot deduct 27.5% (which would be R550,000) — they are capped at R350,000, and the difference is non-deductible this year.

Here is the part people miss: contributions above your annual deductible limit are not lost. The excess is carried forward to the next tax year, where it can be deducted if you have room. It rolls forward indefinitely until it is used. And if it is still unused when you retire, the disallowed contributions reduce the tax on your retirement lump sum, and the portion that buys an annuity comes out tax-free up to the carried-forward amount. So over-contributing is not a penalty the way a TFSA over-contribution is (which gets taxed at 40%) — it is just deferred benefit.

That changes the calculus for a high earner near the cap. If you receive a bonus or sell an asset and have spare cash, contributing beyond R350,000 in one year is reasonable: you bank the deduction for a future year. What you should not do is assume the refund lands this year. Always check whether the 27.5% figure or the R350,000 figure is your real limit before you commit the cash.

Run your own numbers

The two examples above use round salaries and assume no workplace fund. Your real answer turns on three inputs specific to you: your exact taxable income, how much your pension or provident fund already absorbs of the 27.5%, and which bracket your deduction lands in once it pulls your income down. A R10,000 difference in income can change whether the cap binds, and a bracket crossing can knock several percentage points off your blended refund rate.

The tax tool does this calculation for you — it applies the 27.5% test, the R350,000 cap, the 2026 brackets and rebate, and shows the rand refund for your specific income, plus how an RA stacks against a TFSA and Section 13sex for the same cash. Enter your income and current retirement-fund contributions and see your exact deductible amount and refund, then decide how much more to contribute before the tax year closes.
