P11D

Your employer uses form P11D to tell HMRC about the value of any 'benefits in kind' they've given you during the tax year. This means benefits or expenses that effectively increase your income, like:

• a company car
• private medical insurance
• interest-free loans

Your employer will only declare them if you've earned at least £8,500 in the year, including the value of the benefits. They will work out how much each benefit is worth, record it on the form and send it to HMRC. They'll also give you a copy, which you'll need for your records or if you complete a tax return.

If you apply for a loan or mortgage, banks and building societies will accept form P11D as proof of extra income.
