Understanding PAYE in Kenya: A Practical Guide for Employers

Pay As You Earn (PAYE) is the system through which employers in Kenya deduct income tax from employees’ salaries and remit it to the Kenya Revenue Authority (KRA) on their behalf. If you employ even one person earning above the taxable threshold, PAYE compliance is your responsibility, not your employee’s.

1. Who must operate PAYE?

Every employer who pays salaries, wages, bonuses, commissions, or most cash allowances must register for a PAYE obligation on iTax. This applies to:

• Companies of any size, from a two-person startup to a listed group
• Sole proprietors and partnerships with staff on the payroll
• NGOs, schools, churches, and other non-profit employers
• Individuals employing domestic staff above the threshold

Registration is done once, but the obligation runs monthly for as long as you have employees.

2. How the graduated bands work

PAYE is not a flat rate. An employee’s taxable pay is sliced into bands, and each band is taxed at its own rate, rising as income rises. Only the portion of income that falls inside a band is taxed at that band’s rate, which is why a salary increase never leaves anyone worse off after tax.

After computing gross tax across the bands, the monthly personal relief is subtracted to arrive at the PAYE actually withheld. Statutory deductions such as SHIF, NSSF, and the Affordable Housing Levy also affect the arithmetic, because some of them are deductible before tax is applied.

3. Key deadlines to diarise

Obligation	Deadline
PAYE remittance and return (P10)	9th of the following month
Issue P9 forms to employees	End of the tax year
Employee individual returns	30th June

Missing the monthly deadline attracts a penalty of 25% of the tax due (minimum KES 10,000) plus interest, so late filing is one of the most expensive habits a small business can develop.

4. Common mistakes we see

1. Treating allowances as tax-free. Most cash allowances are fully taxable; only a narrow list of benefits enjoys preferential treatment.
2. Forgetting new statutory deductions. Payroll rules have changed several times in recent years, and running last year’s formulas is a fast route to under-deduction.
3. Filing nil returns while paying casual wages. Casual and part-time pay is still employment income in KRA’s eyes.
