Tax estimates

Tax & Self-Employment

Choose a calculator. The interface language, the tax jurisdiction, and the tax year are separate choices.

Each calculator applies a generic engine to a versioned jurisdiction pack. A pack names the calculation profile, the tax year, and the rule version. No result is an official assessment or a filing.

  • VAT calculator

    One rate applies to one amount. A preset rate comes from a released pack. A custom rate is your figure and is not a statutory preset.

  • Income tax estimate

    This is an estimate from the selected pack and tax year. It is not an official tax assessment.

  • Self-employment estimate

    Revenue minus expenses is the profit. Contribution lines come from the pack. They are not a payroll calculation.

Questions

Does the language of this page choose the tax rules?

No. The page language is the interface. The jurisdiction and the tax year are selected in the calculator.

Is the result an official assessment?

No. It is an estimate from a versioned pack, or from a rate you enter for VAT. It is not a filing.
