How PAYE is calculated in Kenya involves a defined, sequential process: establish the employee’s taxable employment income, apply allowable deductions to arrive at taxable pay, apply the current progressive KRA tax bands to calculate gross tax, then subtract personal relief and any other applicable reliefs to arrive at the final PAYE payable. Employers are legally required to deduct this tax from employee emoluments and remit it to the Kenya Revenue Authority (KRA) by the 9th day of the following month
PAYE stands for Pay As You Earn. It is the system through which employers deduct income tax from employment income and remit it to KRA on behalf of their employees. Unlike self-assessment tax, where individuals compute and pay their own tax, PAYE places the deduction and remittance obligation on the employer. Employees do not wait until the end of the year to settle their tax liability; it is withheld at source each month.
The employer’s role is central. Any person who pays emoluments to an employee is required to register for PAYE, deduct tax from those emoluments, and account for the tax deducted to KRA. This applies to both resident and non-resident employees earning Kenyan employment income.
Why does this matter for payroll teams? Because PAYE is not a single flat rate applied to gross salary. It is progressive, band-based, and affected by specific deductions and reliefs that change periodically. An employer who applies outdated bands or incorrectly treats a statutory contribution will deduct the wrong amount, creating underpayment penalties or over-deduction disputes with employees. Getting the calculation right requires using the current verified rules.
How PAYE is calculated in Kenya: the step-by-step process
The PAYE calculation in Kenya follows a consistent sequence. Understanding this sequence is the foundation for accurate payroll processing.
-
Determine gross taxable income. This starts with all cash payments (basic salary, allowances, overtime, bonuses, commissions, director’s fees) plus the value of any non-cash benefits that are chargeable to tax.
-
Apply allowable deductions. Certain contributions reduce the income on which tax is calculated. These include NSSF contributions, approved pension contributions, and SHIF contributions, subject to specific limits. Not every payroll deduction works this way.
-
Calculate taxable pay. Gross taxable income minus allowable deductions equals taxable pay.
-
Apply the tax bands. The progressive monthly tax bands are applied to taxable pay to arrive at gross tax.
-
Subtract personal relief and other reliefs. The monthly personal relief (currently KES 2,400) is deducted from gross tax. Other reliefs, such as insurance relief or mortgage interest relief, may also apply where eligible.
-
Remit the balance. The resulting amount is the PAYE payable, which the employer must remit to KRA by the 9th day of the following month.
What is PAYE in Kenya?PAYE stands for Pay As You Earn. It is a method of collecting individual income tax from employment income. Instead of an employee paying the employment tax directly to KRA each month, the employer deducts the applicable amount from the employee’s pay and remits it to KRA. For example, if an employee earns a monthly salary and the applicable PAYE calculation results in PAYE therefore affects the amount an employee ultimately receives as |

What income is subject to PAYE in Kenya?
Taxable employment income in Kenya includes all cash payments received in respect of employment, however described. According to KRA’s PAYE guidelines, these include wages, salary, sick pay, leave pay, fees, commissions, bonuses, service gratuity, allowances, director’s fees, overtime, pension, and entertainment payments.
Non-cash benefits are also taxable. These include:
-
Value of car benefit (where the employer provides a motor vehicle)
-
Value of housing (where the employer provides residential housing)
-
Loans at interest rates below the prevailing market rate
-
Any benefit or facility exceeding KES 5,000 per month or KES 60,000 per year
Certain income is exempt from PAYE, including meals provided by the employer up to KES 5,000 per month, night-out allowance up to KES 2,000 per day, and employer-provided medical cover. These exemptions apply within specified limits.
A practical point for payroll administrators: the KES 5,000 monthly threshold for non-cash benefits is frequently misunderstood. The threshold does not mean the first KES 5,000 is tax-free. It means the benefit is not taxed if its total value is at or below KES 5,000. Once the value exceeds that amount, the full amount becomes taxable, not just the excess
What deductions are considered when calculating PAYE?
This is where many payroll errors occur. Not all statutory deductions affect taxable income in the same way. Understanding the distinction between allowable deductions, tax reliefs, and non-deductible statutory deductions is essential.
Allowable deductions that reduce taxable income:
-
NSSF contributions. Employee NSSF contributions are allowable deductions up to the statutory limits. From February 2026, the maximum employee NSSF contribution is KES 6,480 per month (Tier I: KES 540; Tier II: KES 5,940).
-
Approved pension contributions. Contributions to registered pension schemes are allowable up to a maximum of KES 30,000 per month, inclusive of NSSF contributions.
-
SHIF contributions. Following the Tax Laws (Amendment) Act, 2024, SHIF contributions (2.75% of gross monthly salary) are now treated as deductible expenses for tax purposes. This means SHIF reduces taxable pay.
-
Post-Retirement Medical Fund (PRMF) contributions. Allowable up to KES 15,000 per month.
-
Mortgage interest. Interest on a mortgage for an owner-occupied house is allowable up to KES 25,000 per month (KES 300,000 annually).
Tax reliefs (subtracted from the tax calculated, not from taxable income):
-
Personal relief. KES 2,400 per month (KES 28,800 annually). This is the most significant relief for most employees.
-
Insurance relief. 15% of premiums paid for life, health, or education policies, capped at KES 5,000 per month (KES 60,000 annually).
Statutory deductions that do NOT reduce taxable income:
-
Affordable Housing Levy (AHL). This is 1.5% of gross monthly salary, matched by the employer. Critically, the AHL is not an allowable deduction for PAYE purposes. It is calculated on gross pay but does not reduce the taxable pay used to calculate PAYE.
This distinction matters. A payroll system that incorrectly deducts AHL before calculating PAYE will understate the employee’s tax liability.
How to calculate PAYE in Kenya step by step
Step 1: Calculate gross taxable income.
Add basic salary, all cash allowances, overtime, bonuses, commissions, and the taxable value of any non-cash benefits.
Step 2: Subtract allowable deductions.
Subtract NSSF (employee contribution, up to KES 6,480), SHIF (2.75% of gross), approved pension (up to KES 30,000 including NSSF), PRMF (up to KES 15,000), and mortgage interest (up to KES 25,000). The result is taxable pay.
Step 3: Apply the tax bands to taxable pay.
Calculate tax for each band progressively.
Step 4: Subtract personal relief and other reliefs.
Deduct KES 2,400 personal relief. Add insurance relief or other applicable reliefs.
Step 5: Result = PAYE payable.
If the result is negative, PAYE payable is zero. Unused personal relief cannot be refunded through PAYE but may be claimed separately.
What is the PAYE filing deadline in Kenya?
Employers must file the PAYE return through iTax and remit the tax deducted on or before the 9th day of the following month. If the 9th falls on a weekend or public holiday, the deadline typically moves to the next working day.
This deadline applies to both filing and payment. Late filing or late payment attracts penalties and interest under the Tax Procedures Act. Payroll teams should build this deadline into their monthly processing calendar to avoid unnecessary exposure.
How payroll software can simplify PAYE calculations
Manual PAYE calculation is possible, but it creates ongoing risk. Every time a statutory rate changes, every time an employee receives a non-cash benefit, and every time a new relief applies, the calculation must be adjusted correctly.
Payroll software centralizes these rules in a single system. When KRA publishes updated bands or when NSSF rates change, the software can be updated once, and all subsequent payroll runs apply the correct logic automatically.
