What This Calculator Estimates
This tool gives a general estimate of Kenyan income tax liability based on the income and rate you provide. Kenya's income tax runs on progressive bands set by the Kenya Revenue Authority (KRA), so someone's effective rate typically rises as taxable income increases, rather than a single flat percentage applying to every shilling earned. Because band thresholds and relief amounts are periodically revised in the Finance Act, this calculator keeps the rate editable so you're not stuck with a number that no longer matches current law.
How to Use This Calculator
- Enter annual income.
- Enter estimated deductions.

Tips for a More Accurate Estimate
- Separate your gross income from any allowances or benefits that may be taxed differently before entering a figure here.
- If you have multiple income sources, KRA may require aggregating them for tax purposes — this calculator handles one figure at a time.
- Business owners should note that allowable business deductions differ from employment-related reliefs.
- Check KRA's iTax portal for the most current published bands before relying on this for filing decisions.
- Treat this as a starting point for planning, not a substitute for a filed tax return.
Frequently Asked Questions
How is this different from the PAYE calculator?
This tool is meant for a broader income tax estimate, while the PAYE calculator is framed specifically around monthly employment withholding. Both use the same editable-rate approach for the same reason: official bands change.
Does Kenya tax worldwide income or only local income?
Kenya generally taxes residents on income sourced within Kenya, with specific rules for foreign-sourced income depending on residency status — this is worth confirming with KRA guidance or a tax advisor for your situation.
What counts as taxable income in Kenya?
Taxable income generally includes employment income, business income, and other income sources after allowable deductions and reliefs, per KRA rules.
Can I use this for business income instead of salary?
You can enter any income figure, but remember business income may have different allowable deductions than employment income, so treat the result as a rough planning estimate.
How often does KRA update tax bands?
Kenya's tax bands are most commonly revised through the annual Finance Act, so it's worth checking KRA's site each fiscal year for the latest figures.
