How to Calculate PAYE in Kenya: Current Tax Bands and Worked Examples

Pay As You Earn (PAYE) is the method through which the Kenya Revenue Authority (KRA) collects income tax from employees. Every employer in Kenya is legally required to deduct PAYE from employee salaries and remit the funds to KRA by the 9th of the following month. Failure to comply attracts penalties of 25% of the unpaid tax plus interest at the prevailing Central Bank rate.

A strong PAYE calculation starts before the tax bands are applied. The payroll team must first decide what counts as taxable employment income, what is allowable as a deduction, which reliefs apply, and whether non-cash benefits or reimbursed expenses should be included. This is where many spreadsheet payrolls fail: the formula may be correct, but the taxable base is wrong.

Current PAYE Tax Brackets

Kenya uses a graduated tax system where each portion of monthly taxable income is taxed at the rate for that band. As at this update, KRA publishes individual income tax bands ranging from 10% to 35%, with personal relief of KES 2,400 per month for resident individuals. The bands apply to taxable employment income after allowable deductions, not simply to the gross salary shown on the employment contract.

Step-by-Step PAYE Calculation

1. 1Start with the employee's gross salary including all taxable allowances such as house allowance, commuter allowance, and overtime pay.
2. 2Add taxable non-cash benefits where applicable, such as motor vehicle benefit, housing benefit, low-interest loan benefit, or other benefits above the allowable monthly threshold.
3. 3Subtract allowable deductions such as employee NSSF, approved pension contributions, eligible post-retirement medical fund contributions, qualifying mortgage interest, Affordable Housing Levy, and SHIF where the current tax treatment allows it.
4. 4The result is the taxable income. Apply the graduated tax rates from the table above to each portion of the taxable income.
5. 5Subtract the personal relief of KES 2,400 per month from the total tax calculated.
6. 6If the employee has an approved insurance policy, subtract insurance relief at 15% of premiums paid, capped at KES 5,000 per month.
7. 7The final figure after all reliefs is the net PAYE to remit to KRA.

Personal Relief and Insurance Relief

Every resident taxpayer in Kenya is entitled to a personal relief of KES 2,400 per month (KES 28,800 annually). This is deducted from the tax payable, not from taxable income. Insurance relief applies where an employee has a life, education, or health insurance policy and is calculated at 15% of the premiums paid, subject to a maximum of KES 5,000 per month.

What Counts as Taxable Employment Income?

KRA treats employment income broadly. Cash payments such as wages, salary, leave pay, commissions, bonuses, overtime, director fees, entertainment allowances, and other employment-related payments normally form part of taxable income. Some non-cash benefits can also be taxable, including employer-provided housing, motor vehicle benefit, low-interest loan benefit, and benefits above the statutory allowance. This means payroll should not only hold a basic salary field; it should support taxable and non-taxable earning categories with a clear audit trail.

Common PAYE Mistakes in Kenyan Payroll

• Applying the tax bands to gross pay without first handling allowable deductions.
• Treating all allowances as non-taxable without checking whether they are taxable employment income.
• Forgetting taxable non-cash benefits such as car benefit, housing benefit, or low-interest loan benefit.
• Using personal relief as a deduction from income instead of a credit against tax payable.
• Changing statutory rates in the payroll system without preserving how older payroll runs were calculated.
• Failing to reconcile the payslip PAYE amount with the PAYE return filed through iTax.

Worked Example: Monthly PAYE Calculation

Consider an employee earning a gross salary of KES 80,000 per month. If the payroll setup treats the current employee-side statutory deductions as allowable before PAYE, taxable income starts from gross pay less employee NSSF, SHIF/SHA, and Affordable Housing Levy. Using Year 4 NSSF rates, employee NSSF would be KES 4,800, SHIF/SHA at 2.75% would be KES 2,200, and Housing Levy at 1.5% would be KES 1,200. The taxable income would therefore be KES 71,800 before reliefs. Applying the bands gives KES 2,400 on the first KES 24,000, KES 2,083 on the next KES 8,333, and KES 11,840 on the remaining KES 39,467. Total tax is KES 16,323. After personal relief of KES 2,400, the net PAYE is about KES 13,923.

Payroll Controls Before You File PAYE

1. 1Review employees added, terminated, or moved between departments during the month.
2. 2Confirm variable pay such as overtime, commission, bonuses, and deductions before payroll approval.
3. 3Compare gross pay, taxable pay, PAYE, SHIF/SHA, NSSF, Housing Levy, and net pay against the prior month.
4. 4Investigate large movement before filing, especially for senior employees, casual conversions, and backdated allowances.
5. 5Lock the approved payroll run so later changes are made through a controlled adjustment instead of editing history.
6. 6Store the payroll summary, payslips, statutory schedules, iTax filing confirmation, and payment receipts together.
