Bonus & 13th Cheque Tax Calculator
SARS doesn't tax bonuses at a separate "bonus rate" — it adds the bonus to your annual income and taxes the total. This calculator shows you exactly how much of your bonus you'll actually take home.

Why does my bonus get taxed so heavily?
It's a common misconception that bonuses are taxed at a flat, higher "bonus tax rate" in South Africa. In reality, SARS simply adds the bonus to your annual salary and recalculates your total tax for the year using the normal progressive brackets. Because the bonus pushes your annual income higher, the portion made up by the bonus is often taxed at your highest marginal rate — which is why it can feel like a large chunk disappears.
Bonus tax FAQs
Is there a separate tax rate for bonuses in South Africa?
No. SARS doesn't apply a special flat "bonus tax rate." Your bonus is added to your annual salary and the combined total is taxed using the normal progressive brackets — for example, on a R25,000.00 salary plus a R25,000.00 bonus, roughly R6,500.00 of the bonus goes to extra tax, an effective rate of about 26% on the bonus itself.
Why does my bonus feel like it's taxed at 40% or more?
Because the bonus is added on top of your existing salary, it often falls entirely within your highest tax bracket, so the rate on that specific slice of income looks much higher than your overall effective tax rate.
Can I reduce the tax on my bonus?
Contributing part of a bonus to a retirement annuity can lower the taxable amount, since RA contributions are tax-deductible up to certain limits. This calculator doesn't model RA contributions — speak to a registered tax practitioner for advice specific to your situation.
Does a 13th cheque get taxed the same way as a performance bonus?
Yes. Whether it's called a 13th cheque, performance bonus, or incentive payment, SARS treats any once-off or irregular payment the same way: added to annual income and taxed under the normal brackets.
