How South Africa Income Tax Works — SARS
South Africa uses a progressive income tax system with 7 brackets from 18% to 45%, administered by the South African Revenue Service (SARS). The key feature is the tax rebate system — instead of a tax-free threshold built into brackets, a fixed rebate (R17,235 primary for under-65s) is subtracted from the calculated tax. This effectively makes income below approximately R95,750 tax-free. The tax year runs from 1 March to 28/29 February — different from most countries.
| Taxable Income (ZAR) | Tax Rate | Tax Threshold (after rebate) |
|---|---|---|
| R0 – R237,100 | 18% | Effective 0% below ~R95,750 |
| R237,101 – R370,500 | 26% | R42,678 + 26% above R237,100 |
| R370,501 – R512,800 | 31% | R77,362 + 31% above R370,500 |
| R512,801 – R673,000 | 36% | R121,475 + 36% above R512,800 |
| R673,001 – R857,900 | 39% | R179,147 + 39% above R673,000 |
| R857,901 – R1,817,000 | 41% | R251,258 + 41% above R857,900 |
| Above R1,817,000 | 45% | R644,489 + 45% above R1,817,000 |
- →Primary rebate: R17,235 (all taxpayers under 65). Secondary rebate: R9,444 (age 65–74). Tertiary rebate: R3,145 (age 75+). These are subtracted from the calculated tax — not from income.
- →Tax thresholds: zero tax below R95,750 (under 65), R148,217 (65–74), R165,689 (75+) — derived from the rebates applied against 18% bracket.
- →UIF (Unemployment Insurance Fund): 1% employee contribution, capped at R177,312 annual gross income — maximum R1,773/year.
- →Medical Aid Tax Credit (MATC): R364/month for the first two medical aid members (main member + first dependent), R246/month for each additional. Directly reduces your tax bill — not just a deduction.
- →Retirement contributions: up to 27.5% of greater of remuneration or taxable income (capped at R350,000/year) deductible. This makes pension/RA contributions one of the most powerful tax reduction tools in SA.
- →Auto-assessment: SARS now auto-assesses most salaried employees using employer IRP5 data, investment income (IT3b), and other third-party data. Review and accept (or edit) on eFiling — no manual filing needed for most employees.
- →Provisional tax: required if you earn non-employment income (rental, freelance, investments) above R30,000/year. Two payments: end of August and end of February.
Frequently Asked Questions
What is the difference between tax rebates and deductions in South Africa?
A deduction reduces your taxable income (useful if you're in a high bracket — a R10,000 deduction saves R4,500 at 45%). A rebate directly reduces your final tax bill by a fixed rand amount regardless of income. South Africa's primary rebate of R17,235 reduces your actual tax payable by R17,235 — this is why someone earning exactly R95,750 pays zero tax (18% × R95,750 = R17,235, exactly offset by the rebate). The Medical Aid Tax Credit (MATC) also works as a rebate — R364/month × 12 = R4,368/year off your tax bill directly.
How does the Medical Aid Tax Credit work?
The Medical Aid Tax Credit (MATC) gives you R364/month credit for the first two medical aid members (you + one dependent) and R246/month for each additional dependent. These credits are applied against your income tax liability — not your income. If you contribute to a qualifying medical aid and are below 65, you get R364 × 12 = R4,368/year directly off your tax bill. People over 65 or with a disability get an enhanced additional medical expenses deduction. The credit does NOT apply to hospital insurance (gap cover) — only registered medical aid schemes qualify.
What is provisional tax and who needs to pay it?
Provisional tax (IRP6) is required for individuals who earn income other than a salary from a single employer — specifically, non-employment income exceeding R30,000/year. This includes rental income, freelance/consulting income, investment income (interest, dividends above the exemption), and business income. You make two advance payments: first estimate by August 31 (for 6 months into the tax year), second by February 28 (year end). A third optional payment is due September 30 after assessment. If your advance payments fall short of the final liability by more than 20%, SARS charges interest on the shortfall.
When do South Africans need to file a tax return?
SARS sends auto-assessments to most salaried employees — you receive an SMS and can review it on eFiling. If you agree with the auto-assessment, no action is needed. You must file a return (ITR12) if: you earn non-employment income above R30,000; you disagree with your auto-assessment; you have foreign employment income; you emigrated or have foreign assets above R250,000; you want to claim additional deductions not in the auto-assessment. The filing season for non-provisional taxpayers is typically July–October. Provisional taxpayers have until January 23. Late filing penalties start at R250–R16,000 depending on income level.
