Tax basics for your South African payslip

Short answer
Gross salary is the amount before deductions. PAYE is calculated from taxable income, while UIF is a capped contribution. Pension contributions, medical aid, benefits, and rebates can change the final number, which is why two people with the same gross salary can take home different amounts.
Gross is the starting point, not the finish line
Gross salary is the amount before deductions. PAYE is calculated from taxable income, while UIF is a capped contribution. Pension contributions, medical aid, benefits, and rebates can change the final number, which is why two people with the same gross salary can take home different amounts.
- Start with gross monthly salary.
- Separate statutory deductions from voluntary deductions.
- Treat any online estimate as a planning tool, not a payroll statement.
PAYE and UIF do different jobs
PAYE is a withholding tax collected through payroll. UIF is a social insurance contribution with a cap. They show up together on a payslip, but they are not interchangeable and they do not respond to salary changes in the same way.
- PAYE generally rises as taxable income rises.
- UIF reaches its cap at a lower salary than many people expect.
- Your employer's payroll calculation remains the source of truth.
Use the calculator as a conversation starter
Run a take-home-pay estimate when you compare a job offer, review a raise, or plan a new monthly budget. If the result differs from your payslip, look at benefits, tax credits, pension, and other deductions before assuming the calculator is wrong.
Worked South African example
For example, enter a R30,000 monthly salary, review the indicative PAYE and UIF lines, and then use the estimated take-home amount in a monthly budget.
