Indonesia Income Tax Calculator
Estimate income tax in Indonesia across a tax-free allowance and two rate bands, with effective and marginal rates.
About Indonesia 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 Indonesia. 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
Indonesia Income Tax
Tax = (band 1 income × basic rate) + (income above the threshold × higher rate)
- allowance
- Income taxed at zero per cent
- threshold
