Managing Pay As You Earn (PAYE) in Kenya is a critical aspect of payroll compliance for all businesses, regardless of size. The regulatory landscape is dynamic, with recent Finance Acts introducing significant changes that impact how employers calculate and remit taxes. As of July 5, 2026, businesses must be fully conversant with the latest allowable deductions, their respective caps, and the procedural shifts to ensure accurate payroll processing and avoid penalties from the Kenya Revenue Authority (KRA).

PAYE is a system designed to collect income tax from employees at the source, making employers indispensable agents in the tax collection process. This system ensures a steady flow of government revenue while allowing employees to meet their tax obligations incrementally throughout the year. For Kenyan Small and Medium-sized Enterprises (SMEs), corporates, and entrepreneurs, a thorough understanding of these provisions is not merely a compliance task but a strategic imperative for sound financial management and employee satisfaction.

The Finance Act 2025, effective July 1, 2025, brought a pivotal change by mandating employers to automatically apply all eligible tax reliefs and exemptions when computing employees’ PAYE, thereby streamlining the process and reducing the burden on employees who previously had to seek refunds directly from the KRA. This shift underscores the need for robust payroll systems and up-to-date knowledge within every organisation.

Navigating Key Allowable PAYE Deductions in Kenya

Allowable deductions are amounts subtracted from an employee’s gross emoluments to arrive at the taxable income, which is then subjected to the applicable tax rates. These deductions effectively reduce an individual’s tax burden. It is crucial to distinguish between deductions, which lower taxable income, and reliefs, which reduce the final tax payable.

The Income Tax Act (Cap 470) and subsequent Finance Acts govern these provisions, with the KRA providing guidelines for their application. Employers must ensure their payroll software and processes are configured to correctly identify and apply these deductions for each employee, based on their individual circumstances and supporting documentation.

Staying informed about the latest amendments is paramount. For instance, while the Finance Bill 2026 did not include proposed PAYE relief for lower-income workers as some had anticipated, it is essential to focus on the deductions and reliefs that are currently in force, as detailed in recent legislative updates.

Personal Relief: A Universal Benefit

Personal Relief is a fundamental tax relief granted to all resident individuals in Kenya. This relief is designed to lighten the overall tax burden on taxpayers, offering a direct reduction from the calculated tax payable, rather than a deduction from the taxable income itself. It is a fixed amount that every eligible employee can claim.

For the tax year 2026, Personal Relief is set at KSh 2,400 per month, amounting to KSh 28,800 per annum. Employers are responsible for factoring this relief into their monthly PAYE calculations, thereby reducing the net tax remitted to the KRA on behalf of their employees.

Social Health Insurance Fund (SHIF) Contributions

The Social Health Insurance Fund (SHIF) replaced the National Hospital Insurance Fund (NHIF) from October 2024, becoming a mandatory statutory deduction. SHIF contributions are fully deductible from an employee’s taxable income, meaning the amount contributed reduces the gross earnings before PAYE is calculated.

The rate for SHIF contributions is 2.75% of the gross salary, without an upper earnings limit. This deduction is a crucial component of Kenya’s social security framework, aiming to provide comprehensive health insurance coverage for all citizens. Employers must accurately deduct and remit SHIF contributions alongside other statutory payments by the 9th of the following month.

Mortgage Interest Relief: Supporting Homeownership

Mortgage Interest Relief serves as a significant incentive for Kenyan residents to achieve homeownership. This relief allows individuals to deduct a portion of the interest paid on a qualifying mortgage from their taxable income, directly reducing their PAYE liability.

To be eligible for this relief, the mortgage must be from an approved financial institution and must be for the purchase or improvement of premises occupied by the individual for residential purposes. The relief is capped at KSh 30,000 per month, translating to KSh 360,000 per annum.

Eligibility and Qualifying Loans

For an employee to qualify for Mortgage Interest Relief, they must be a Kenyan resident. The loan must originate from one of the financial institutions specified in the Fourth Schedule to the Income Tax Act. These typically include commercial banks and other registered lenders. The property in question must be the individual’s principal residence.

The Finance Act 2025 expanded the scope to include construction costs as part of the deductible mortgage interest, further broadening the applicability of this relief. Additionally, the Finance Bill 2026 proposes to allow a deduction for interest on loans advanced by the Central Bank of Kenya to an employee for the construction, purchase, or improvement of a residential house, also capped at KSh 360,000 per year.

  • Residential Occupancy: The property for which the mortgage interest is claimed must be occupied by the taxpayer for residential purposes, serving as their primary home rather than an investment property.
  • Approved Lenders: The mortgage must be obtained from a financial institution that is explicitly approved and registered under the relevant sections of the Income Tax Act, ensuring legitimacy and compliance.
  • Annual Cap Adherence: The maximum allowable deduction for mortgage interest is strictly capped at KSh 360,000 per annum, or KSh 30,000 per month, irrespective of the total interest paid in a given year.
  • Supporting Documentation: Taxpayers must retain official interest certificates or statements from their lenders to substantiate the interest amounts paid, which are crucial for KRA verification during audits.
  • Principal vs. Interest: Only the interest portion of the mortgage repayment is eligible for relief; the principal repayment component remains non-deductible for tax purposes.

Insurance Relief: Securing Your Future

Insurance Relief is another vital tax incentive designed to encourage Kenyans to take up life, health, and education insurance policies. This relief provides a reduction in the tax payable, thereby promoting financial security and access to essential services for individuals and their families.

The relief is calculated at 15% of the premiums paid for qualifying policies. This benefit is capped at a maximum of KSh 5,000 per month, or KSh 60,000 per annum. It is a direct reduction from the tax liability, similar to Personal Relief, and significantly contributes to lowering an individual's overall tax burden.

Conditions and Maximum Benefits

For an insurance policy to qualify for relief, it must be for life insurance, health insurance, or an education policy. In the case of education policies, a specific condition requires the policy to have a maturity period of at least 10 years. The premiums can be paid for the individual, their spouse, or their children.

Employees seeking to claim Insurance Relief must provide their employers with the necessary supporting documentation, typically a certificate from their insurer detailing the premiums paid. Employers then factor this into the monthly PAYE computation. Without proper documentation, the relief cannot be applied, highlighting the importance of diligent record-keeping for both employees and employers.

  • Life Insurance Policies: Premiums paid for policies that secure a capital sum payable in Kenya and are denominated in Kenyan currency are eligible for relief, promoting long-term financial planning for dependents.
  • Health Insurance Policies: Contributions towards health insurance for the taxpayer, their spouse, or children qualify for relief, supporting access to medical care and reducing out-of-pocket health expenses.
  • Education Policies: Premiums for education policies are eligible, provided the policy has a minimum maturity period of ten years, encouraging structured savings for future educational needs.
  • Maximum Annual Relief: The total insurance relief that can be claimed is limited to KSh 60,000 per annum (KSh 5,000 per month), regardless of the total premiums paid if they exceed this threshold.
  • Documentation for Employers: Employees must furnish their employers with valid insurance premium certificates from their respective insurance providers to enable accurate calculation and application of the relief in payroll.

Approved Pension and Provident Fund Contributions

Contributions made to registered pension or provident funds represent a crucial allowable deduction, encouraging individuals to save for their retirement. The government provides tax incentives to foster a culture of long-term savings, recognising the importance of financial security in post-employment years.

For the tax years 2025 and 2026, the maximum allowable deduction for contributions to registered pension or provident funds, or registered individual retirement funds, is KSh 30,000 per month, or KSh 360,000 per annum. This limit applies to both employee and employer contributions.

This deduction directly reduces an employee's taxable income, thereby lowering their PAYE liability. It is a significant benefit for employees planning for their future, and for employers, it forms part of a competitive compensation package. The Tax Laws (Amendment) Act, 2024, increased this limit, reflecting a governmental push to enhance retirement savings.

Beyond the regular contributions, certain pension-related payments are fully exempt from PAYE. For instance, pension income derived from registered retirement benefit schemes is exempt from tax for individuals who have attained the retirement age defined by their schemes, or who withdraw accrued benefits due to ill health, or after a minimum of 20 years of membership. Similarly, an amount not exceeding KSh 360,000 paid by an employer as gratuity into a registered retirement pension scheme for each year of service is also exempt.

The Affordable Housing Levy (AHL): A Mandatory Deduction with Tax Benefits

The Affordable Housing Levy (AHL) is a mandatory statutory contribution introduced under the Affordable Housing Act, 2024, to fund the government’s affordable housing programme. This levy affects all employed persons in Kenya, both in the formal and informal sectors, and represents a significant addition to the statutory deductions landscape.

The AHL is calculated at 1.5% of an employee’s gross monthly salary, with the employer also contributing a matching 1.5%. Both portions are remitted to the KRA through the PAYE filing system by the 9th of the following month. Crucially, the employee’s contribution to the AHL is classified as an allowable deduction for PAYE purposes. This means the 1.5% is subtracted from the employee’s gross salary before income tax is calculated, providing a direct reduction in their taxable income.

Unlike some other deductions, there is no upper earnings limit or cap for the Affordable Housing Levy, meaning it is applied to the full gross monthly salary. This makes accurate calculation and timely remittance paramount for employers to maintain compliance and avoid penalties. The levy is a key social policy initiative aimed at addressing Kenya’s significant housing deficit.

  • Employee Contribution Rate: Each employed individual is mandated to contribute 1.5% of their gross monthly salary towards the Affordable Housing Levy, directly impacting their net take-home pay.
  • Employer Matching Contribution: Employers are required to remit a matching 1.5% contribution based on each employee's gross monthly salary, adding to the overall cost of employment.
  • Gross Salary Basis: The levy is calculated on the employee's total gross income, which encompasses basic salary and all regular cash allowances, without any upper earnings limit or cap.
  • PAYE Deductibility: The employee’s 1.5% contribution is an allowable deduction for PAYE purposes, meaning it reduces the taxable income before income tax is computed.
  • Remittance Deadline: Both employee and employer portions of the AHL must be remitted to the Kenya Revenue Authority (KRA) via the iTax portal by the 9th day of the subsequent month, aligning with PAYE remittance schedules.
  • Non-Compliance Penalties: Failure to remit the AHL on time attracts a penalty of 3% per month on the outstanding unpaid amount, which can significantly escalate costs for businesses.

Other Important Exemptions and Deductible Benefits

Beyond the primary deductions and reliefs, several other exemptions and benefits impact an employee's taxable income, further refining the PAYE computation. Employers must be aware of these provisions to ensure accurate payroll processing and compliance with the Income Tax Act.

These additional considerations often relate to specific types of allowances, non-cash benefits, and certain payments made upon retirement or termination of employment. Understanding these nuances is crucial for both employers and employees to maximise tax efficiency and avoid misinterpretations that could lead to penalties.

The continuous evolution of tax legislation, often through annual Finance Acts, necessitates ongoing vigilance. Businesses should regularly review KRA guidelines and consult with tax professionals to ensure their payroll practices remain fully compliant with the latest regulations, particularly concerning benefits that may be partially or wholly exempt from tax.

Tax-Free Per Diem Allowance

The Finance Act 2025, effective July 1, 2025, significantly increased the tax-exempt threshold for per diem allowances. Employees working out of their usual station or outside their usual workplace on official duties can now receive up to KSh 10,000 per day in per diem without it being subject to tax. This represents a substantial increase from the previous limit of KSh 2,000 per day.

Amounts exceeding KSh 10,000 per day must be substantiated with documentation; otherwise, the excess will be treated as taxable income. This adjustment reflects the rising cost of living and aims to provide more realistic allowances for employees on official assignments, simplifying expense management for employers.

Exempt Non-Cash Benefits and Meal Benefits

Certain non-cash benefits and meal provisions by an employer are also exempt from PAYE up to specific thresholds. The value of a benefit, advantage, or facility granted to an employee in respect of employment is exempt where its aggregate value is less than KSh 5,000 per month, or KSh 60,000 per year.

Similarly, the first KSh 5,000 per month (or KSh 60,000 per year) on the value of meals provided by an employer in a canteen or cafeteria operated by them or a registered third party for the benefit of employees is also exempt from tax. These exemptions aim to provide clarity on the taxability of minor employee benefits.

Post-Retirement Medical Fund Contributions

Contributions made by an employee to a registered post-retirement medical fund are also an allowable deduction from taxable income. This deduction is capped at KSh 15,000 per month. This provision encourages individuals to plan for their healthcare needs in retirement, aligning with broader social welfare objectives.

This deduction, along with pension contributions, highlights the government's efforts to provide incentives for long-term financial and health planning. Employers should ensure that their payroll systems correctly identify and apply this deduction for eligible employees, based on proof of contribution to a registered fund.

Common Mistakes Businesses Make

Even with clear guidelines, businesses often encounter pitfalls in PAYE management, leading to penalties and compliance issues. Avoiding these common mistakes is crucial for maintaining a good standing with the KRA and ensuring smooth payroll operations. Proactive measures and regular reviews of payroll processes are essential.

Ignorance of the latest legislative changes, misinterpretation of specific deduction rules, or simply administrative oversight can all result in non-compliance. These errors not only attract financial penalties but can also lead to time-consuming audits and reputational damage. Businesses must therefore invest in robust internal controls and continuous training for their payroll teams.

The KRA’s increasingly automated compliance systems, which include eTIMS invoicing validation and iTax return matching, mean that errors are now more likely to be detected automatically, triggering penalties without manual intervention.

  • Incorrect Application of Tax Bands: Many businesses fail to apply the correct progressive PAYE tax bands, especially with frequent legislative updates, leading to either under-deductions or over-deductions of tax from employee salaries.
  • Missing or Outdated Reliefs and Deductions: Overlooking the automatic application of eligible reliefs such as Personal Relief, Insurance Relief, or the Mortgage Interest Relief, particularly after the Finance Act 2025 mandates employer application, results in incorrect tax calculations.
  • Inaccurate Affordable Housing Levy Calculation: Miscalculating the 1.5% Affordable Housing Levy on gross salary, or failing to remit both employee and employer portions by the 9th of the following month, is a common error that attracts significant penalties.
  • Late Filing and Payment of PAYE: Failing to file the monthly PAYE return and remit the deducted tax by the 9th day of the subsequent month invariably triggers penalties of 25% of the tax due or KSh 10,000 (whichever is higher) for late filing, and 5% of the tax due plus 1% interest per month for late payment.
  • Inadequate Record-Keeping: Not maintaining comprehensive and accurate payroll records, including P9 forms, payslips, and supporting documentation for deductions like insurance or mortgage interest, can lead to disallowed claims during KRA audits.
  • Ignoring Non-Cash Benefit Taxability: Overlooking the taxability of certain non-cash benefits provided to employees, particularly those exceeding the KSh 5,000 monthly exemption threshold, can result in under-declaration of taxable income.

What Your Business Should Do Now: An Action Checklist for PAYE Compliance in 2026

Ensuring full PAYE compliance in Kenya for 2026 requires proactive measures and a systematic approach.
