Use the correct tax bracket table
This calculator applies the cumulative upper limits and marginal rates you enter. It does not automatically choose a country’s tax rules or tax year. Replace the sample table with rules that apply to your situation.
Each rate applies only to income inside its band. The deduction is removed first, limits must increase and the last limit must be Infinity. Credits and surcharges are excluded.
