Calculation basis and official references

Reviewed on:

Formula basis

For each category, tax = net amount × its rate, rounded using the selected rule. Gross = net + rounded tax, and the two independently rounded results are added.

Calculation method

This calculator applies two separate consumption-tax rates to two tax-exclusive amounts, then totals the tax and tax-inclusive prices.

Exclusions and checks required

  • Only two rate categories are supported, and the calculator does not classify goods as reduced-rate, standard-rate, exempt, or outside scope.
  • Rounding each category separately can differ from accounting that rounds once across an entire invoice.
