PAYE Explained: How Income Tax Is Calculated in Kenya
Published March 2026
Pay As You Earn (PAYE) is the system used in Kenya to collect income tax from employees. Under this system, employers deduct income tax directly from an employee’s salary before the salary is paid and remit the tax to the Kenya Revenue Authority (KRA). The goal of PAYE is to ensure that income taxes are collected regularly and efficiently while spreading the tax burden across the year instead of requiring employees to make large lump-sum payments.
PAYE is calculated based on taxable income and applies progressive tax rates introduced in the Finance Act 2023. A progressive tax system means that higher portions of income are taxed at higher rates. Employees also benefit from tax reliefs such as the personal relief which reduces the total tax payable each month.
Step 1: Calculate Gross Taxable Income
The first step in calculating PAYE is determining the employee’s gross taxable income. This includes the basic salary as well as other earnings such as allowances, commissions, bonuses, overtime payments, and other benefits that form part of employment income. Essentially, gross taxable income represents the total amount earned before statutory deductions are applied.
Step 2: Deduct Allowable Deductions
After determining gross income, certain allowable deductions are subtracted to determine the taxable pay. The most common deduction is the National Social Security Fund (NSSF) contribution, which is deducted from the employee’s salary. Other pension contributions that qualify under tax rules may also reduce taxable income. Once these deductions are removed, the remaining amount becomes the employee’s taxable pay used for calculating PAYE.
Step 3: Apply the Monthly Tax Bands
Kenya uses progressive tax bands introduced under the Finance Act 2023. Each portion of income falls into a different tax bracket, and the applicable rate is applied to that portion only. The monthly PAYE bands are structured as follows:
- First KSh 24,000 – taxed at 10%
- Next KSh 8,333 – taxed at 25%
- Next KSh 467,667 – taxed at 30%
- Next KSh 300,000 – taxed at 32.5%
- Income above KSh 800,000 – taxed at 35%
Because the tax system is progressive, only the portion of income within each band is taxed at the corresponding rate. This ensures that individuals with higher earnings pay a larger share of tax while protecting lower-income earners from heavy taxation.
Step 4: Subtract Personal Relief
After calculating the gross tax from the tax bands, employees are entitled to a personal relief of KSh 2,400 per month. This relief directly reduces the tax payable. Personal relief is applied uniformly to all qualifying employees and helps lower the final PAYE amount deducted from monthly income.
Example PAYE Calculation
Consider an employee whose taxable income is KSh 50,000 per month. The PAYE calculation would be performed step by step across the tax bands.
- First KSh 24,000 taxed at 10% = KSh 2,400
- Next KSh 8,333 taxed at 25% = KSh 2,083.25
- Remaining KSh 17,667 taxed at 30% = KSh 5,300.10
The total gross tax comes to approximately KSh 9,783. After applying the monthly personal relief of KSh 2,400, the final PAYE payable would be about KSh 7,383.
Other Statutory Deductions
In addition to PAYE, Kenyan employees typically have other statutory deductions taken from their salaries. These deductions include the Social Health Insurance Fund (SHIF), which is calculated at 2.75% of gross income, and the Housing Levy which requires a 1.5% contribution from employees and a matching 1.5% contribution from employers. While these deductions are not part of PAYE, they affect the employee’s final take-home salary.
When PAYE Is Paid
Employers are responsible for deducting PAYE from employees’ salaries every month and remitting the collected taxes to the Kenya Revenue Authority. The remittance must be made by the 9th day of the following month. Failure to remit PAYE on time can result in penalties and interest charges for the employer.
Why PAYE Matters
PAYE is one of the largest sources of government revenue in Kenya and plays a critical role in financing public services such as infrastructure, healthcare, education, and security. By collecting taxes directly from salaries, the system simplifies tax compliance for employees while ensuring that the government receives a steady stream of revenue throughout the year.
For employees, understanding how PAYE is calculated is important for financial planning and verifying payroll deductions. Reviewing payslips regularly helps ensure that taxes and other statutory deductions are correctly applied and remitted.
