How is tax calculated in South Africa?
South Africa uses a progressive PAYE (Pay As You Earn) system. Your employer estimates your annual income, applies the SARS tax brackets, subtracts your tax rebate, and divides the result over 12 months — that's the income tax taken off each payslip.
On top of PAYE, 1% UIF is deducted from your gross salary (capped at R177.12/month). If you contribute to a retirement annuity or pension, that amount lowers your taxable income — which reduces your PAYE. Medical aid contributions earn a fixed monthly tax credit per member.
Example: R25 000 salary breakdown
- Gross salaryR 25 000
- PAYE (income tax)− R 3 483
- UIF (1%, capped)− R 177
- Net take-homeR 21 340
Effective tax rate: 13.9%. That means roughly 14c of every rand earned goes to SARS as income tax.
Why your take-home pay is lower than expected
Most South Africans look at their gross salary and assume they'll see most of it in their bank account. The reality is that PAYE, UIF, pension, medical aid and group life all come off before payday.
- Marginal vs effective tax: moving into a higher bracket doesn't tax your whole salary at the new rate — only the portion above the threshold. But it still shrinks your raise.
- Bonuses are taxed in full: your once-off bonus is added to annual income, often pushing it into a higher bracket for the year.
- Salary structuring: travel allowances, company car fringe benefits and provident funds all change taxable income.
