UK P11D Calculator

P11D total of taxable benefits = sum of all BIK items.

⚠ 2024-25 UK tax-year figures. Estimates only — consult HMRC or a tax adviser.

How to use UK P11D Calculator

  1. Enter the benefit-in-kind details (e.g., company car value, CO2 emissions band, private fuel).
  2. The calculator estimates the taxable benefit value for P11D reporting purposes.

Limitations

  • Company car benefit rates depend on CO2 bands that are updated by HMRC periodically — always cross-check against the current tax year's official P11D rates before filing.
