Understanding P11D Value

What P11D value means and how it's used to calculate company car tax in the UK.

What is P11D Value?

The P11D value (also called "list price") is the official taxable value used to calculate Benefit in Kind (BiK) tax on company cars. It's named after the HMRC form P11D, which employers use to report expenses and benefits provided to employees.

For company cars, the P11D value is the car's recommended retail price when new, including VAT and any factory-fitted accessories. This value remains fixed throughout the car's life, regardless of depreciation or market value changes.

How P11D Value Affects Your Tax

The P11D value is the starting point for calculating your company car tax. A higher P11D value means higher BiK tax, even if you negotiated a discount or the car has depreciated.

Example Impact

Base Model P11D:£35,000

With £5,000 Options:£40,000

BiK tax increase (25% BiK rate, 40% taxpayer):

Extra annual tax:£500/year (£42/month)

Important: Every £1,000 added to the P11D value increases your annual BiK tax by £20-£168 depending on the car's BiK percentage and your income tax rate. Consider carefully whether expensive options are worthwhile.

Finding a Car's P11D Value

1. Manufacturer's Price List

Check the manufacturer's official price list for the exact specification. This shows the "on the road" price minus road tax and first registration.

2. Online Configurators

Use the manufacturer's website to build the exact specification. The total price (with VAT) is the P11D value.

3. Your Employer

Your HR or fleet manager should provide the P11D value when you choose a company car.

4. Form P11D

Check your P11D form (sent annually after the tax year ends) which shows the exact value used for tax calculations.

Capital Contributions

If you make a capital contribution (an upfront payment towards the car's cost), you can reduce the P11D value used for BiK calculations by up to £5,000.

Example

Original P11D value:£40,000

Your capital contribution:£5,000

Reduced P11D for tax:£35,000

Tax Saving (25% BiK, 40% taxpayer):

Annual saving:£500/year

Contribution paid back in 10 years of reduced tax

Maximum deduction is £5,000. Contributions above this amount don't provide additional tax benefits. Capital contributions are not refunded if you return the car.

Using Car Cost Comparison

Benefit in Kind is calculated from the P11D list price, not from what was paid. Car Cost Comparison uses that list price:

Enter the P11D value including factory-fitted options
See how list price feeds the cash equivalent and income tax
Compare personal purchase costs using the same list price

Figures are illustrative. They are not a recommendation of which specification to choose.
