PAYE in Kenya 2026: Employer's Complete Guide to Calculation, Filing & Penalties

Pay As You Earn (PAYE) is the income tax deduction mechanism that every Kenya employer with at least one employee on a payroll must operate. Administered by the Kenya Revenue Authority (KRA) under the Income Tax Act (Cap 470), PAYE requires employers to compute, deduct, and remit income tax on behalf of their employees every month — before the salary lands in the employee's account. Errors cost money. Late remittances attract a 5% penalty on the outstanding tax plus interest at 1% per month. Underpayments attract the same charges, and deliberate non-compliance can result in criminal prosecution of company directors. This guide covers everything you need to know to operate PAYE correctly in 2026.

Who Must Register for PAYE?

Any employer — company, NGO, foreign branch, individual employer, or government body — that pays emoluments to employees in Kenya must register for PAYE. Emoluments include salaries, wages, allowances, benefits in kind, directors' fees, and deemed employment income. There is no minimum payroll threshold. Even if you have a single employee earning below the tax-free band, you are still required to register so that you can file a nil return each month.

Registration is done through the KRA iTax portal. You will need your company's KRA PIN, a valid business permit, and the National Identification details of the authorised tax representative. Foreign nationals on Kenya payroll also require an individual KRA PIN for expatriates before they can be processed through PAYE.

2026 PAYE Tax Bands

Kenya operates a graduated (progressive) PAYE system. The current income tax bands applicable to employment income in the 2025/2026 tax year are as follows:

• First KES 24,000 per month (KES 288,000 per year): taxed at 10%
• Next KES 8,333 per month (KES 288,001 – KES 388,000 per year): taxed at 25%
• Next KES 467,667 per month (KES 388,001 – KES 6,000,000 per year): taxed at 30%
• Next KES 300,000 per month (KES 6,000,001 – KES 9,600,000 per year): taxed at 32.5%
• Income above KES 9,600,000 per year (above KES 800,000 per month): taxed at 35%

Every employee is entitled to a monthly personal relief of KES 2,400, which is deducted directly from the computed tax liability. Insurance relief of 15% of premiums paid (capped at KES 5,000 per month) also applies where applicable. Always verify the most current bands on the KRA official website, as the Finance Act may adjust rates annually.

How to Calculate PAYE: A Worked Example

Consider an employee earning a gross monthly salary of KES 150,000 with no other allowances or benefits in kind.

1. Tax on first KES 24,000: KES 24,000 × 10% = KES 2,400
2. Tax on next KES 8,333: KES 8,333 × 25% = KES 2,083
3. Tax on remaining KES 117,667 (150,000 − 24,000 − 8,333): KES 117,667 × 30% = KES 35,300
4. Gross PAYE: KES 2,400 + KES 2,083 + KES 35,300 = KES 39,783
5. Less personal relief: KES 39,783 − KES 2,400 = KES 37,383 net PAYE payable

Benefits in kind — company car, employer-paid rent, employer-paid school fees — are taxed at prescribed rates under the Income Tax Act and must be added to cash emoluments before calculating PAYE. Many employers understate benefits in kind; this is one of the most common findings in a KRA PAYE audit.

Statutory Deductions Running Alongside PAYE

PAYE is only one of several monthly statutory obligations. Every Kenya payroll must also account for:

• NSSF (National Social Security Fund): Under the NSSF Act 2013 (as upheld by the Court of Appeal in 2023), Tier I contributions are 6% of pensionable pay up to KES 7,000 (employee) plus a matching employer contribution. Tier II contributions apply to income above KES 7,000 up to the upper earnings limit. Visit NSSF Kenya for the current schedule.
• SHIF (Social Health Insurance Fund): Replaced NHIF from October 2023. The contribution rate is 2.75% of gross salary, with no upper cap. Both employer and employee contribute. Visit the Social Health Authority for current rates.
• Housing Levy: 1.5% of gross salary deducted from the employee plus a 1.5% matching employer contribution, remitted to the Kenya Mortgage Refinance Company.
• NITA Levy: Employers with more than five employees must contribute KES 50 per employee per month to the National Industrial Training Authority.

Together, these obligations make Kenya payroll significantly more complex than simply deducting income tax. A missed or miscalculated statutory deduction typically triggers back-payments with interest and penalties during a KRA or NSSF audit.

Filing PAYE Returns on KRA iTax

PAYE is filed monthly on iTax using the P10 monthly return. The process requires you to:

1. Log into the iTax portal with your company PIN and password.
2. Download the P10 Excel template and populate each employee's earnings, deductions, and PAYE amounts for the month.
3. Upload the completed P10 template and generate an e-slip (payment registration number).
4. Pay the PAYE amount via M-Pesa, bank transfer, or KRA agent bank using the e-slip reference before the 9th of the following month.

An annual P9 form must be issued to each employee by the 28th of February each year, summarising their total emoluments and tax deducted for the previous year. Employees use the P9 to file their individual income tax returns on iTax.

PAYE Deadlines and Penalties

The PAYE remittance deadline is the 9th of each month for the previous month's deductions. Filing a return without paying by this date is treated as a late payment. Consequences include:

• A 5% penalty on the outstanding PAYE amount, applied on the day after the deadline
• 1% interest per month on the tax outstanding (compounding)
• Late filing penalty of KES 10,000 for a nil return filed after the due date
• Potential director's liability for deliberate non-remittance

Employers who discover historical PAYE errors should consider a voluntary disclosure to KRA. The authority does offer penalty waivers in some circumstances, but this requires experienced tax advisory support to navigate correctly.

Common Employer Mistakes

Based on our HR and payroll compliance audits across 385+ client organisations, the most frequent PAYE errors we find are:

• Failing to tax benefits in kind (company car, employer-paid rent, medical over the exempt limit)
• Using outdated tax band tables from a prior Finance Act year
• Not registering casual workers earning above the threshold for PAYE
• Misclassifying employees as contractors to avoid PAYE obligations
• Not applying the correct pension relief for registered occupational schemes
• Filing a nil return without also issuing a zero P9 to employees
• Failing to account for PAYE on termination payments (gratuity above the exempt threshold is taxable)

When Payroll Outsourcing Makes Sense

For most organisations with fewer than 200 employees, the cost of maintaining a dedicated payroll team with current iTax, NSSF, SHIF, and Housing Levy knowledge exceeds the cost of outsourcing. Our managed payroll service in Kenya handles the entire compliance cycle — P10 filing, NSSF, SHIF, and Housing Levy — for a fixed monthly fee with a zero-penalty guarantee. We also conduct annual payroll audits for organisations that want independent verification of their in-house processing. For companies without a Kenyan legal entity, our Employer of Record service handles the entire employment and payroll obligation under our entity.
