How the calculation works
The calculator applies the rates in the order the law does: band by band where a country taxes profit in slices, or one rate to the whole profit where eligibility decides the rate. Surcharges are applied to the tax, local business taxes to the profit. The result is an estimate: it does not include loss relief, tax credits, deferred tax or group rules.
