Frequently Asked Questions About Benefits in Kind
For the 2026/27 tax year, the Benefit in Kind (BIK) tax rate for pure zero-emission electric vehicles (0 g/km CO2) is 3% of the car's list price (P11D value).
Multiply the car's official P11D value (list price including options and VAT) by its CO2 emissions BIK percentage, then multiply that taxable benefit by your personal income tax rate (20%, 40%, or 45%).
BIK tax is typically collected through your monthly PAYE salary by adjusting your HMRC tax code down, or directly through your employer's payrolled benefits system.
