How is income tax calculated in South Africa?
South Africa uses a progressive tax system. The more you earn, the higher the percentage of tax you pay — but only on the portion of your income that falls inside each bracket. You don't pay 31% on your whole salary just because you cross into the 31% bracket; only the rand earned above the bracket boundary is taxed at that rate.
Once your tax is calculated from the brackets, SARS subtracts rebates that everyone gets. The primary rebate (currently R17,820 per year) means the first R99,000 you earn is effectively tax-free if you are under 65. People 65 and older get an additional secondary rebate, and those 75 and older get a third tertiary rebate on top.
If you contribute to a medical scheme, you get a fixed monthly tax credit per member that reduces your PAYE further. If you contribute to a Retirement Annuity, that contribution comes off your taxable income before the brackets are applied — so your tax bill drops, although the contribution itself still leaves your bank account.
UIF (Unemployment Insurance Fund) is a separate deduction. It is 1% of your gross salary, capped at R177.12 per month. Your employer pays another 1% on your behalf.

Frequently asked questions
What is the tax threshold for 2026/2027?▾
If you are under 65, you pay no income tax on annual earnings below R99,000. For ages 65–74 the threshold is R153,250, and for 75 and older it is R171,300.
How is UIF calculated?▾
UIF is 1% of your monthly gross salary, capped at R177.12 per month — the cap is based on the SARS earnings ceiling of R17,712 per month. Your employer matches this with another 1%.
Do I need to file a tax return?▾
If your only income is a salary below R500,000 from one employer and PAYE has been deducted, SARS may automatically assess you. If you have multiple income sources, claim deductions like RA contributions, or earned more than R500,000, you must file.
What is the difference between PAYE and income tax?▾
PAYE (Pay-As-You-Earn) is the system your employer uses to deduct income tax from your salary each month and pay it to SARS on your behalf. The tax itself is income tax — PAYE is just how it is collected.
How do medical aid tax credits work?▾
Medical scheme fees tax credits reduce your tax payable each month. For 2026/2027 it is R376 for the main member, R376 for the first dependent, and R254 for each additional dependent. The credits apply automatically through PAYE if your employer pays your scheme.
