Bonus Tax Calculator South Africa 2026/2027

How bonuses are taxed in South Africa

SARS does not tax bonuses at a separate flat rate. Instead, SARS treats a bonus as an annual payment. Your bonus is added once to your annual pay and the total tax is recalculated. The difference between your tax with and without the bonus is the PAYE deducted from your bonus.

This means your bonus is effectively taxed at your marginal tax rate: the rate that applies to the highest portion of your income. If your annual salary puts you in the 26% bracket, most of your bonus will be taxed at 26%, with any portion that pushes you into the 31% bracket taxed at 31%. The PAYE Calculator in the box above shows the PAYE and effective rate on your salary alone.

The SARS annual payment method, step by step

Worked example: R25,000 salary + R25,000 bonus

Will you get a tax refund on your bonus?

Possibly. The PAYE on your payslip is your employer's withholding, worked out from SARS's tables on your salary annualised to 12 months; your final tax is set when SARS assesses your year against what you actually earned. If more was withheld than you owe, for example because you started mid-year or pay into a retirement annuity privately, the assessment refunds the difference. A salary of R500,000 or less from one employer that deducted PAYE could exempt you from filing for the 2026 year of assessment under SARS's filing notice, but a return is how you claim a deduction payroll did not apply, so check what a return would refund before you skip it.

Real-world example: a higher earner's bonus

The example above shows a R25,000/month earner whose bonus falls entirely within the 26% bracket. Higher earners often see a different picture. Consider an employee earning R45,000/month (R540,000/year) who receives a R40,000 performance bonus, bringing their annual income to R580,000, still inside the 36% bracket.

Notice the effective rate jumped from 26% to 36% simply because this employee's salary alone already sits in the 36% bracket. This is the core mechanic to understand: your bonus tax rate depends on where your combined annual income lands, not on any special "bonus rate".

13th cheque vs performance bonus: same tax treatment

Whether your bonus is a guaranteed contractual "13th cheque" paid every December, or a discretionary performance bonus tied to targets, SARS treats both identically for tax purposes. Both are added to your annual income and taxed via the annual payment method described above. The only practical difference is predictability. A contractual 13th cheque lets you plan around a known bonus tax hit each year, while a discretionary bonus is harder to budget for since the amount (and therefore the marginal tax impact) can vary year to year.

Common bonus tax mistakes to avoid

The most frequent misreading is comparing a bonus-month payslip with a normal month's. The bonus month carries the PAYE on the bonus on top of the normal month's PAYE, so the whole payslip looks heavily taxed even though your salary is taxed exactly as before; compare the bonus line alone with the tax on the bonus shown above. A second common mistake is expecting your payslip's bonus-month deduction to be your final tax liability on the bonus; it is only an estimate, and the actual amount is only confirmed once SARS processes your annual tax return.

A third mistake, particularly relevant for employees who change jobs mid-year, is forgetting that a bonus received from a previous employer still counts towards your total annual income when your new employer or SARS calculates your final tax position. If you received a bonus from Employer A in June and started at Employer B in August, both the bonus and the subsequent salary form part of the same tax year's calculation. Leaving the first employer's IRP5 off your return can result in an unexpected tax bill.

Does bonus tax affect your retirement contributions?

If your employer deducts retirement fund contributions as a percentage of your total remuneration (including bonuses), as many provident fund rules do, a bonus month can temporarily increase your retirement contribution alongside the extra tax. Check with your payroll department, since some retirement fund rules calculate contributions only on basic salary while others include variable pay like bonuses and commission. Where bonuses are included, this can push your annual retirement contributions closer to the Section 11F deduction cap (the lesser of R430,000 a year, 27.5% of the greater of your remuneration or taxable income, and your taxable income; the R430,000 figure was announced in Budget 2026, legislation pending), which may reduce your taxable income further and partially offset the bonus tax hit, but only if you have room left under the cap. Use our Retirement Annuity Calculator to check how much deduction room you have left this tax year.
