South Africa Income Tax Calculator

Estimate income tax in South Africa across a tax-free allowance and two rate bands, with effective and marginal rates.

About South Africa 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 South Africa. 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

South Africa Income Tax

Tax = (band 1 income × basic rate) + (income above the threshold × higher rate)

allowance
Income taxed at zero per cent
threshold
