South Africa income tax calculator

No tax-free band — a rebate that creates one

The South African scale starts taxing at the first rand, at 18.0%. There is no exempt band. What produces the threshold below which nobody pays is something else: a rebate subtracted from the tax after it is calculated.

The primary rebate is R17 820. Because the first rate is 18.0%, the income at which the tax exactly equals the rebate is R17 820 ÷ 18.0% = R99 000 — and R99 000 is precisely the tax threshold SARS publishes.

That relationship is worth stating because it is checkable, and this site checks it: if the rebate and the published threshold did not reconcile, one of the two would have been transcribed wrong. At R99 000 the calculator returns R0.

The mechanism has the same distributional logic as Canada's basic personal amount: a fixed amount off the tax is worth the same to everyone, where an exempt band is worth your marginal rate on it. South Africa reaches the same place by a different route.

Additional rebates apply from age 65 and again from 75, raising the threshold substantially for older taxpayers. Only the primary rebate is applied here, so for anyone over 65 this figure is an overstatement.

Seven bands, and a top rate that arrives late

The scale has seven bands running from 18.0% to 45.0%. On R500 000 the tax is R98 417 after the rebate — an effective rate of 19.7% against a marginal band of 31.0%.

The top rate of 45.0% does not begin until R1 878 600, which is a long way up. For almost everyone the relevant part of the scale is the section below R887 000.

SARS publishes the scale as a cumulative amount plus a rate on the excess — "R44 118 + 26.0% of taxable income above R245 100" — rather than as a list of rates. That format is unusually explicit and it makes verification easy: the engine here is checked against those cumulative amounts at every band boundary.

Checking against published amounts rather than percentages is what catches a displaced threshold. A band that starts one rand off produces perfectly plausible percentages and the wrong money, and only the cumulative figure reveals it.

The tax year runs 1 March to the end of February, so the 2027 tax year covers 1 March 2026 to 28 February 2027. That is a fourth distinct pattern among the countries on this site.

What comes off a South African payslip that is not here

UIF. The unemployment insurance contribution is 1% of remuneration up to a monthly ceiling, matched by the employer. Everyone in formal employment pays it and it is not in the figure above.

Medical scheme fees tax credits. These are fixed monthly amounts per member and per dependant, subtracted from tax in the same way as the rebates. For a family they are substantial, and omitting them makes this figure an overstatement for anyone on a medical scheme.

Retirement fund contributions. Deductible within limits, and for anyone contributing to a pension, provident or retirement annuity fund they reduce taxable income before the scale applies.

The secondary and tertiary rebates. From 65 and from 75, they raise the threshold to R153 250 and R171 300 respectively. Only the primary rebate is applied here.

Put together, a South African payslip and this figure can differ meaningfully in both directions — UIF pushes the deduction up, the medical credits and retirement contributions push the tax down. That is why the boundary is stated rather than approximated.

The scale at four incomes

The rebate flattens the bottom of the curve and the seven bands steepen the middle, so the effective rate climbs faster through the middle of the range than at either end.

On R200 000: R18 180 of tax after the R17 820 rebate, an effective rate of 9.1% with a marginal rate of 18.0%.

On R400 000: R67 417 of tax after the R17 820 rebate, an effective rate of 16.9% with a marginal rate of 31.0%.

On R700 000: R169 033 of tax after the R17 820 rebate, an effective rate of 24.1% with a marginal rate of 39.0%.

On R1 200 000: R370 293 of tax after the R17 820 rebate, an effective rate of 30.9% with a marginal rate of 41.0%.

The gap between effective and marginal is widest in the middle rows, which is where the rebate still matters relative to the bill and the higher bands have started to bite.

Four ways a South African estimate goes wrong

Looking for a tax-free band. There is not one. The scale taxes from the first rand and the rebate creates the threshold afterwards. Modelling it as an exempt band gives the wrong answer everywhere except at the threshold itself.

Applying only the primary rebate to an older taxpayer. From 65 the secondary rebate adds R9 765 and from 75 the tertiary adds R3 249, raising the threshold substantially.

Forgetting the medical scheme credits. They come off the tax like the rebates and for a family they are a significant amount, so a figure without them overstates the bill.

Using the wrong tax year. It runs 1 March to end February, so the 2027 tax year is mostly calendar 2026. A figure labelled with a calendar year is ambiguous at best.

Where these figures come from

The scale, the rebates and the thresholds all came from SARS — Rates of Tax for Individuals (2027 tax year), rebates and thresholds, read on 2026-09-02. SARS publishes several years on the same page, and this is the 2027 tax year table specifically.

That multi-year publication is itself a hazard: a page showing four tables one after another is easy to read from the wrong one, and the years are labelled by the year the tax year ends rather than the year it mostly falls in.

The engine reproduces the cumulative amounts SARS publishes at every band boundary — R44 118, R79 998, R125 599, R259 783, R666 339 — and the test asserts that the primary rebate and the published threshold reconcile at 18.0%.

What is not modelled is stated under the calculator: UIF is not deducted. The unemployment insurance contribution is 1% of remuneration up to a monthly ceiling, matched by the employer, and it comes off the payslip. Medical scheme fees tax credits are not applied. They are fixed monthly amounts per member and dependant, subtracted from tax like the rebates, and for a family they are substantial. Retirement fund contributions are deductible within limits and are not deducted here.

The arithmetic is deterministic. The AI explains figures it is given and never produces one.

How South Africa compares with the rest of this site

Against Canada, the mechanism is the same idea reached independently: a fixed amount subtracted from the tax rather than an exempt band. Canada calls it the basic personal amount and computes it as a credit at the lowest rate; South Africa calls it the primary rebate and subtracts it directly. Both are worth the same to everyone, which an exempt band is not.

Against the UK and Australia, the contrast is the missing exempt band. Both of those exempt a first slice of income outright; South Africa taxes from the first rand and rebates afterwards, which produces the same threshold and a different distribution above it.

Against the US, the scale is steeper and arrives sooner in local terms, and there is no sub-national income tax layer at all — no provincial or municipal schedule of the kind that makes the US side of this site thousands of pages long.

Against India, both use credits and rebates rather than allowances, and both publish their scales as a cumulative amount plus a rate on the excess — a format that makes verification straightforward and that this site takes advantage of in both cases.

The transferable point across all ten: whether relief is delivered as an exempt band, a deduction, a credit or a rebate changes who benefits, even when the threshold looks identical.

PAYE, and the reconciliation most people never see

Tax is deducted monthly by the employer under PAYE, calculated by annualising the month's pay and applying the scale and rebates. For a steady salary that lands close to the right figure.

It lands badly for irregular pay. A large bonus in one month is annualised as though it repeated all year, so the deduction that month is disproportionate — and the reconciliation happens on assessment rather than in the pay cycle.

Medical scheme fees tax credits are applied through PAYE where the employer administers the scheme, and claimed on assessment where they do not. That difference alone can make two people with identical cover see different monthly deductions.

SARS issues auto-assessments to a growing share of taxpayers, populated from employer, bank and medical scheme data. Accepting one that omits a deduction you were entitled to is easier than noticing it, which is the risk auto-assessment introduces.

Filing season for individuals opens after the tax year ends in February. Anyone with retirement annuity contributions, medical expenses beyond the credits, or income the employer did not see has something to gain from filing rather than accepting.

Four more ways an estimate goes wrong

Reading the SARS page from the wrong table. Several tax years are published one after another on the same page, and they are named for the year the tax year ends rather than the year it mostly falls in.

Treating the rebate as an exempt band. They produce the same threshold and different results above it. A rebate is worth R17 820 to everyone; an exempt band of the same size would be worth your marginal rate on it, which at 45.0% would be more than twice as much.

Using gross salary as taxable income. Retirement fund contributions are deductible within limits and come off before the scale applies, so entering gross overstates the bill for anyone contributing.

Forgetting that the tax year straddles the calendar. It runs 1 March to end February, so a bonus paid in January and one paid in April fall in different tax years despite being three months apart.

Three rebates, two extra thresholds

The primary rebate of R17 820 applies to everyone. The secondary rebate of R9 765 is added from age 65, and the tertiary rebate of R3 249 from age 75.

They stack. A taxpayer aged 75 or over receives all three, which is why South Africa publishes three tax thresholds rather than one: roughly R99 000 under 65, and materially higher at each of the two age steps.

The mechanism is worth being precise about, because it is not the same as an age-related allowance. The rebate reduces the tax computed by the scale; it does not reduce the income the scale is applied to. Two people with the same income and different ages therefore face the same marginal rate and different total tax.

A rebate cannot go below zero. Someone whose computed tax is less than their rebates pays nothing and receives nothing — there is no refundable element, unlike some credits elsewhere.

The age is measured at the end of the tax year, so someone turning 65 in January of a tax year ending in February qualifies for the full year's secondary rebate. The calculator applies the rebate you select.

Medical scheme fees credits, the other fixed subtraction

Alongside the rebates, South Africa gives a medical scheme fees tax credit: a fixed monthly amount for the main member, the same again for the first dependant, and a smaller fixed amount for each additional dependant.

Like the rebates, it is a credit against tax and not a deduction from income, so it is worth the same regardless of your marginal rate. That was a deliberate reform: the previous deduction-based system was worth more to higher earners for identical cover.

A separate additional medical expenses credit picks up out-of-pocket costs and contributions above a multiple of the fixed credit, with a more generous formula for taxpayers over 65 or with a disability. It is claimed on assessment, not through payroll.

Neither is modelled in the figure above, which applies the scale and the age rebates only. Anyone on a medical scheme should treat the result as an overstatement of their actual liability.

They are described here because leaving them unexplained would make the calculator's number look wrong to most South African employees, whose PAYE already reflects the fixed credit where the employer administers the scheme.

Reading the SARS table without misreading it

SARS publishes the scale as a cumulative amount plus a rate on the excess: for a band starting at R245 100, the table reads as a fixed rand figure plus 26.0% of the amount above it.

That format is easier to verify than a list of rates, because each row states an amount that must equal the tax at the band's floor. This site's tests check exactly that — every published cumulative figure is reproduced by the engine — which is the strongest available evidence that the thresholds are entered correctly.

The top rate of 45.0% begins at R1 878 600. There is nothing above it: no surcharge, no additional band, no separate high-income levy of the kind India and Ireland both apply.

Below the top, the steps are close together by international standards — seven bands, with the first four falling inside the first R695 800. The scale climbs quickly relative to local salaries, which is why the effective rate rises steeply through the middle of the range.

Tax years are named for the year in which they end. The year ending 28 February 2027 is referred to as the 2027 year of assessment despite ten of its twelve months falling in 2026, and picking the wrong row off a page listing several years is the most frequent source of a plausible but wrong South African estimate.

UIF and SDL, the two charges outside the scale

Unemployment Insurance Fund contributions are deducted from wages at a flat percentage, matched by the employer, and capped at a monthly earnings ceiling. Above the ceiling the contribution stops, so it is a fixed rand amount for most salaried professionals rather than a percentage of pay.

The Skills Development Levy is paid by the employer on payroll above an annual threshold and never appears as an employee deduction, though it is part of the cost of employing someone.

Neither is income tax and neither is modelled here. UIF is the one that shows on a payslip, and its effect on take-home is small and flat rather than progressive.

Mentioning them matters for the same reason ACC matters in New Zealand and PRSI in Ireland: the gap between a tax figure and a net-pay figure is made of charges like these, and a calculator that does not name them invites the reader to assume there are none.

Questions

How much tax do I pay on R500 000 in South Africa?

R98 417 after the R17 820 primary rebate — an effective rate of 19.7% with a marginal rate of 31.0%. UIF comes off on top; medical scheme credits and retirement contributions would reduce it.

What is the tax threshold in South Africa?

R99 000 for someone under 65. It is not an exempt band: the scale taxes from the first rand at 18.0%, and the R17 820 primary rebate cancels the tax up to exactly that income. From 65 and from 75 further rebates raise it to R153 250 and R171 300.

Does South Africa have a tax-free band?

No, and the distinction matters. Other systems exempt a first slice of income; South Africa taxes everything and then subtracts a fixed rebate from the tax. The effect at the threshold is the same and the effect above it is not — a rebate is worth the same to everyone, an exempt band is worth your marginal rate on it.

Is UIF included in this figure?

No. The unemployment insurance contribution is 1% of remuneration up to a monthly ceiling, matched by the employer, and everyone in formal employment pays it. It is a real deduction and it is stated as excluded rather than folded in.

What about medical scheme credits?

Not modelled. They are fixed monthly amounts per member and dependant, subtracted from tax in the same way as the rebates, and for a family they are substantial — so the figure above overstates the bill for anyone on a medical scheme.

When does the South African tax year run?

1 March to the end of February, and it is named for the year it ends in. The 2027 tax year therefore covers 1 March 2026 to 28 February 2027, which is mostly calendar 2026.
