FAQ

Questions UK Income Tax Calculator owners ask.

  • 01

    How does the Personal Allowance tapering work?

    If your annual earnings exceed £100,000, your Personal Allowance is reduced by £1 for every £2 earned above this threshold. This effectively increases the tax rate on income in this range.

  • 02

    What National Insurance classes are supported?

    The capability supports Class 1 NI (for employees) and Class 4 NI (for self-employed individuals).

  • 03

    Can I get a full breakdown of my take-home pay?

    Yes, by using the get_tax_summary_report capability, you can receive a comprehensive report including total income tax, total NI contributions, and your final net take-home pay.
