Estimate ordinary individual income tax in Kenyan shillings using monthly or annual bands. Gross-pay mode separates taxable non-cash benefits, deductions allowed for tax and contributions actually paid. Resident-only personal and insurance reliefs are applied after the progressive tax calculation. Automatic NSSF uses the 2026 contribution ceilings by payroll date.

Formula

Taxable income = cash pay + taxable benefits − allowed deductions − valid PWD exemption. PAYE = max(progressive tax − personal relief − min(15% of qualifying insurance premiums, relief cap), 0). Cash after PAYE = cash pay − tax − actual listed cash deductions; non-cash benefits are excluded from cash received.

Examples

Monthly salary with statutory contributions

Cash salary KES 100,000; employee NSSF 6,000, AHL 1,500 and SHIF 2,750. Taxable income 89,750; resident PAYE 19,308.35; cash after those deductions 70,441.65.

A PRACTICAL GUIDE

When to use this calculator

Kenyan PAYE and take-home cash depend on both taxable benefits and actual cash deductions. This calculator separates those concepts so that a non-cash benefit can affect tax without being incorrectly added to the money the employee receives.

Information to prepare

Prepare cash pay, benefits, qualifying deductions and the applicable month. Review pension limits and the insurance-relief calculation rather than entering a premium as if it were the tax reduction itself. Confirm the NSSF, housing levy and health-insurance amounts or assumptions used in the selected case.

How to interpret the result

Gross salary, taxable pay, contribution earnings and cash received can be different amounts. A non-cash benefit may increase tax without increasing the deposit, while a cash deduction may reduce take-home pay without being deductible for tax. Compare the bases and individual lines before comparing totals alone. Timing also matters: the monthly equivalent of an annual estimate does not necessarily reproduce a payslip containing arrears, variable benefits or cumulative adjustments. Keep the stated scope of each tax and contribution component visible.

A practical comparison

When comparing two payslips, examine taxable income, relief and cash deductions separately. Similar taxable incomes can produce different cash deposits when benefits or deductions differ. The PAYE result is one component of the breakdown, while VAT on a personal or business purchase is a separate obligation.

Check your calculation step by step

  1. Match the figures to the selected period and use KES for monetary inputs. If you start with a document in another currency or covering several periods, resolve that difference before entering a combined amount.
  2. Calculate the documented case first. Then change one input at a time to compare scenarios. Keep the original values available so a change in the result can be traced to a particular assumption rather than several simultaneous edits.
  3. Read the component breakdown alongside the formula and examples below. If an official document differs, check the date, base, rounding and omitted concepts before changing a rate or treating the difference as an error.

Frequently asked questions

Is KES 5,000 the monthly insurance premium limit?

No. It is the monthly tax-relief cap. A qualifying premium of KES 10,000 gives KES 1,500 relief. Relief reaches KES 5,000 when 15% of the premiums reaches that amount. Annual relief is capped at KES 60,000 and applies to resident individuals.

What NSSF rate applies in 2026?

Employee and employer each contribute 6% of pensionable wages up to the applicable ceiling. The employee ceiling is KES 4,320 in January and KES 6,480 from February. The annual option assumes equal monthly wages and combines both stages.

Do tax caps reduce the cash contribution paid?

No. The form keeps actual pension and medical-fund payments separate from their tax-deductible portions. Registered pension contributions, including NSSF, share the deduction limit; it also cannot exceed 30% of pensionable income.

Are AHL and SHIF insurance tax reliefs?

They are deductible contributions under the current rules, not additional 15% insurance relief. Automatic employee AHL is 1.5% of the applicable salary base; SHIF is 2.75% with a KES 300 monthly minimum. Enter assessed contributions or adjusted bases where necessary.

Why does taxable-income mode not show take-home salary?

Taxable income can include non-cash benefits and exclude amounts still paid in cash. Gross-pay mode is needed to estimate cash after deductions. Mortgage interest and insurance premiums reduce payroll cash only when selected as deducted from that pay.
