A bonus is added to that month’s pay and taxed at your highest band, which is why most of it is taxed at 30% or more.

Quick answer

A KSh 50,000 bonus on a KSh 80,000 salary leaves you KSh 32,337 after PAYE, SHIF and Housing Levy.

Why bonuses feel heavily taxed

Kenya has no separate bonus tax. Your bonus is added to that month’s salary and run through the normal PAYE bands. Because it sits on top of your salary, almost all of it falls into your highest band, usually 30%, so the tax on the bonus is higher than your average tax rate.

SHIF (2.75%) and the Housing Levy (1.5%) are also charged on the bonus because both are based on gross pay. NSSF usually does not rise, since most salaries are already above the KSh 108,000 Tier II ceiling or close to it.

Ways to keep more of a bonus

Ask whether your employer can pay part of the bonus into a registered pension scheme. Pension contributions are deductible up to KSh 30,000 a month, so a one-off contribution in the bonus month reduces the PAYE on it. Splitting a bonus across months does not usually help, because each month is still taxed at your top band.

Frequently asked questions

How is a bonus taxed in Kenya?

A bonus is added to your salary for the month it is paid and taxed through PAYE using the normal bands of 10% to 35%. SHIF at 2.75% and the Housing Levy at 1.5% also apply to it.

Is there a tax-free bonus amount?

No. Unlike some countries, Kenya does not exempt any part of a cash bonus. Only specific items, such as bonus or overtime for low-income employees in certain cases, have special treatment.

Why is my bonus taxed at 30%?

Because it sits on top of your salary, it falls into your highest PAYE band. For anyone earning above about KSh 32,333 in taxable pay, that band is 30%.

Does NSSF apply to bonuses?

NSSF is capped at pensionable pay of KSh 108,000 a month. If your normal salary is already above that, the bonus adds no extra NSSF.
