What is a P11D?

Step 01

What a P11D is

GOV.UK explains that your employer might submit a P11D to tell HMRC if you get benefits in kind — for example a company car or an interest-free loan. Employers also report many expenses and benefits under the wider expenses-and-benefits rules (company cars, health insurance, travel and entertainment, childcare, and similar). The exact reporting and tax treatment depend on the benefit type.

Most employees do not fill in a P11D themselves. The employer files; you may get a copy or a record of what was reported.

Step 02

What it is not (and payrolling)

A P11D is not your Self Assessment tax return and not your P60 end-of-year summary. If your employer takes the tax you owe on benefits out of your pay (payrolling), GOV.UK says they will not need to submit a P11D for those benefits — they should write to you to explain how that works. Employer guidance also notes you still may need other returns (such as P11D(b) for Class 1A National Insurance) in some cases; that is an employer topic, not this page.

Step 03

Getting your P11D details

If you need the figures, ask your employer for a record of what they reported on the P11D, including how much each benefit is worth. If they cannot give you one, contact HMRC. GOV.UK also says that at the end of each tax year your employer will give you details of company benefits they told HMRC about — which might be a copy of your P11D. Keep those details for **2 years** after the tax year they relate to. Tell HMRC about company benefits you or your family start or stop getting from work, even if tax and National Insurance were already taken through payroll — follow GOV.UK company-benefits guidance for the exact process.

Step 04

How it can affect take-home and coding

Taxable benefits can change the Income Tax you owe and may feed into your tax code or end-of-year bill. If something on a benefit statement looks wrong, ask payroll first, then check what HMRC holds for you.
