How much of your salary you keep in South Africa

Published May 18, 2026 · 3 min read

A clear way to estimate net salary in South Africa from gross pay, using an effective income tax rate and a social contributions rate.

Gross, net and everything in between

Gross salary is the figure in your contract. Net salary is what reaches your bank account after income tax and social contributions such as pension, health or unemployment insurance. In South Africa the exact deductions depend on your income, residence, family situation and employer arrangements.

Worked example

Here is the calculation with sample figures. Change any number in the South Africa Salary After Tax Calculator to run your own.

Use an effective rate, not the top rate

Income tax is usually progressive, so only the slice of income in a higher band is taxed at the higher rate. Your effective rate, total income tax divided by gross income, is almost always lower than your top marginal rate. The calculator asks for an effective rate so you can plug in a figure from a recent payslip or tax return.

Monthly versus annual

Divide the annual net by 12 for a monthly figure, but remember that some countries pay 13 or 14 salaries a year, and bonuses can be taxed differently.

Quick reference at 15%

Common amounts in South Africa, worked both ways: adding tax to a net price, and extracting it from a price that already includes tax.

How South Africa compares
