Tax Calculator 2026 (South Africa): SARS 2026/27 Rates & the Four Levers That Move Your Answer

This piece grew out of a real planning question: what is the tax on R600,000 for someone aged 36, and how low can it legally go? The calculator above answers the first half — for a 36-year-old earning R600,000 in 2026/27, the answer is R132,907 a year, an effective rate of 22.15% in the 36% marginal bracket. The rest of this article answers the second half: how far that number can legally fall, and what it costs you to get there. Along the way it clears up a naming trap that trips up almost everyone searching for a "tax calculator 2026".

Which year is the "2026 tax year"?

SARS names a tax year by the calendar year in which it ends. So the 2026 year of assessment runs from 1 March 2025 to 28 February 2026 — that is the return most people file from mid-2026. The year you are living and earning in right now is the 2026/27 year (1 March 2026 to 28 February 2027), which closes in the 2027 year of assessment.

This matters because planning only helps for a year that is still open. The brackets in the calculator default to 2026/27 — the year you can still influence — but the toggle lets you check the 2026 figures for the return that is due now. The 2026 Budget, tabled on 25 February 2026, shifted the brackets up 3.4% for inflation, the first such relief since 2023/24.

It is worth being precise about how the R132,907 is built, because the same arithmetic underpins every scenario below. On a R600,000 taxable income the tax before rebates is R150,727; subtract the R17,820 primary rebate and you are left with R132,907 payable, which is R11,075.58 a month off your payslip as PAYE. Nothing about that number is a choice — it is what you pay if you claim nothing. Everything interesting happens once you start using the deductions and credits the ITR12 was built to capture.

What the ITR12 actually lets you claim

The annual return — the ITR12 — separates two very different mechanisms. Deductions reduce the income that gets taxed; their value depends on your marginal rate, so a deduction is worth more the higher your bracket. Credits reduce the tax bill itself, rand for rand, regardless of bracket. Optimising your tax affairs is mostly a matter of knowing which boxes on the ITR12 turn which lever, and having the paperwork to support each one.

Deductions that reduce your taxable income

Retirement fund contributions — Section 11F. The most powerful lever for a salaried earner. You may deduct the lesser of 27.5% of the greater of your remuneration or taxable income, and R430,000 a year — a cap lifted from R350,000 on 1 March 2026, its first move since 2016. At R600,000 the 27.5% ceiling is R165,000, comfortably inside the cap. Crucially, anything you contribute over the limit is not lost: SARS programmatically carries the excess forward to the next tax year, where it counts toward that year's deduction.

Donations to Section 18A organisations. Donations to a SARS-approved public benefit organisation are deductible up to 10% of taxable income, with the excess again carried forward. You need a valid Section 18A tax certificate, and the PBO number must be entered on your ITR12, where SARS validates it automatically. The honest framing: this is not a way to keep more money — you are giving it away — but if you were going to give anyway, the deduction means SARS effectively co-funds the gift.

Home office expenses — Section 11(a), read with s23(b) and s23(m). As a salaried employee your ability to claim general expenses is heavily restricted, but a home office can qualify if you meet strict criteria: the space must be specifically equipped and used solely for your trade (a dedicated study, not the dining table), you must perform more than half of your duties from it, and you need a letter from your employer confirming you are permitted to work from home. Most salaried earners will not clear all three bars, which is why this lever rarely features in the headline scenarios below — but for genuine remote workers it is real.

Travel expenses. If your package includes a taxable travel allowance (IRP5 code 3701), you can deduct business travel — but only against a meticulous logbook of daily business kilometres. No logbook, no deduction. It is the most commonly forfeited claim on the return, purely for want of record-keeping.

Credits that reduce your tax bill directly

Medical scheme fees credit — Section 6A. A flat monthly credit that comes straight off your tax, regardless of your bracket: R376 each for the main member and first dependant, and R254 for every dependant after that (the 2025/26 figures were R364 and R246). Because it is fixed, it does not change which planning route is best — it simply lowers every scenario by the same amount.

Additional medical expenses credit — Section 6B. For high out-of-pocket costs. Under 65 and without a disability, the credit is 33.3% of the amount by which your qualifying out-of-pocket expenses plus "excess" scheme contributions (those above three times your Section 6A credit) exceed 7.5% of taxable income. It is a high threshold, so it tends to matter only in years with a major medical event.

One credit people still ask about no longer applies: the residential solar tax credit (25% up to R15,000) existed only for the 2024 year of assessment. It is not available for 2026/27, so leave it out of your planning.

R600,000, the default versus full optimisation

To see what these levers are worth, start with the two extremes. Scenario A claims nothing. Scenario B is fully optimised: the maximum R165,000 into a retirement annuity, the maximum R43,500 donation (10% of the post-RA R435,000), and a single-member medical credit.

Two deductions move you out of the 36% bracket and into the 31% one, and the medical credit shaves the bill again. Net tax falls from R132,907 to about R57,296 — roughly R75,611 saved for the year, with the effective rate more than halving. On the 2025/26 rates the same exercise lands at R135,632 versus R62,269, a R73,363 saving; the shape is identical, the inflation-adjusted brackets just nudge the figures.

> The retirement contribution alone carries most of the benefit — and it does double duty: the R165,000 saves you tax today and compounds tax-free inside the fund for retirement.

What "take-home" really means

Here is where the comparison gets honest. "Lowest tax" and "most money in your pocket" are not the same thing, because two of these levers spend cash to save tax.

In Scenario A you pay R132,907 in tax and keep R467,093 as liquid cash — about R38,924 a month — with nothing saved. In Scenario B your tax drops to R57,296, but you also spent R165,000 on the RA and R43,500 on the donation, so liquid take-home cash falls to about R334,204 (~R27,850 a month). Your monthly spendable cash drops by roughly R11,074 — yet your total retained wealth (cash plus the RA asset) rises to about R499,204, because SARS subsidised R75,611 of those contributions. You feel poorer month to month and are wealthier overall.

That tension is why a third route matters. Scenario C — the "smart saver" — maxes the R165,000 RA and claims the medical credit but makes no donation. Tax lands around R72,500, liquid cash is about R362,500 (~R30,208 a month), and because nothing is given away, total retained wealth is the highest of the lot at about R527,500. You have simply redirected money that would have gone to SARS straight into your own retirement.

Scenario D: adding a tax-free savings account

A TFSA behaves unlike the deductions. Contributions are not tax-deductible — you fund it with after-tax money, so it does not lower this year's taxable income. Its power is on the other side: all interest, dividends and growth inside it are exempt forever, withdrawals are tax-free, and the 2026/27 annual limit is R46,000 (up from R36,000), with a R500,000 lifetime cap. Over-contribute and SARS levies a 40% penalty on the excess, so the limit applies across all your TFSAs combined.

Scenario D keeps the R165,000 RA and splits the R43,500 that was a pure donation in B between giving and a TFSA. Split 1 sends 60% to the TFSA (R26,100) and 40% to a donation (R17,400); Split 2 reverses it. Both TFSA amounts sit safely under the annual limit.

The verdict on Scenario D is that it buys you a balanced middle ground. By redirecting R26,100 out of a permanent donation and into your own TFSA, Split 1 lifts total retained wealth to about R515,500 — roughly R16,000 more in your corner than the all-donation Scenario B — while you still give R17,400 to a cause and claim the matching deduction. And the money in the TFSA now compounds in a completely tax-free environment alongside the RA, which is about as efficient as long-term wealth building gets in South Africa.

The caveat the comparison hides

A rand in a retirement annuity is not the same as a rand in cash or a TFSA. RA money is locked until age 55, and when you eventually draw it, the income portion is taxed at your marginal rate then — so part of today's deduction is really tax deferred, not tax avoided. A TFSA, by contrast, is fully liquid and never taxed again, and cash is already yours.

That is why the "retained wealth" column slightly flatters the RA-heavy routes, and why the "best" scenario is genuinely personal. Scenario C wins on raw retained wealth, but only if you are comfortable locking the most away and giving nothing. Scenario D keeps more liquid and more flexible. Scenario B does the most social good. The right balance depends on when you will need the money, what your tax rate is likely to be in retirement, and what you want your money to do — which is exactly the judgement a licensed adviser is for, not a calculator.
