A P11D reports the cash value of benefits in kind (BIKs) an employee or director receives on top of salary: a company car, employer-paid fuel, a van with private use, a cheap loan, private medical insurance. The employee pays income tax on that value at their marginal rate, and the employer pays Class 1A National Insurance at 15%. Enter your benefits below to see the 2026/27 taxable value and both tax bills.
The manufacturer's list price when new, including VAT, delivery and factory options, not what was actually paid. Enter 0 if there is no company car.
0 for a pure electric car. Shown on the V5C or the manufacturer's spec sheet.
Only matters for plug-in hybrids emitting 1 to 50 g/km. Longer electric range means a lower BIK percentage.
Money you personally put towards the cost of the car reduces the list price for the benefit calculation, capped at £5,000.
Interest-free or cheap loans, including an overdrawn director's loan account. No benefit arises if the balance stays at £10,000 or below all year.
The premium your employer pays for your cover. The taxable value is simply the cost to the employer.
Benefits are reported on a P11D by 6 July after the tax year, or taxed in real time through payroll if the employer has registered to payroll benefits. Payrolling most benefits becomes mandatory from April 2027, so employers still on P11Ds should plan the switch now.
