Kenya Income Tax Calculator
Estimate income tax in Kenya across a tax-free allowance and two rate bands, with effective and marginal rates.
About Kenya Income Tax Calculator
Progressive systems tax each slice of income at its own rate rather than applying one rate to the whole amount. That is why the effective rate is always below the marginal rate — only the last slice is taxed at the top rate you reach. Indicative bands for Kenya. Confusing the marginal rate with the effective rate leads people to believe a pay rise leaves them worse off, which progressive banding never does.
Formula
Kenya Income Tax
Tax = (band 1 income × basic rate) + (income above the threshold × higher rate)
- allowance
- Income taxed at zero per cent
- threshold
