A P11D form is a document used by a business to inform HMRC about the employee benefits provided to employees. For example, any extras such as corporate cars or private health insurance.
You can report these to HMRC on your yearly Self Assessment return using the annual P11D form.
You might not receive a P11D if your employer deducts the tax you owe on your benefits from your wages.

When do I need to file a P11D?
P11D forms must be submitted to HMRC by the 6th of July after the end of the tax year. For example, the tax year 2021–22 ends on April 6, 2022 will require P11D forms to be submitted by July 6, 2022.
It is up to the employer to submit the P11D form, not the employee. If you fail to file your P11D form on time, you will face financial penalties. This starts with a £300 fine, followed by a £60 fine a day until HMRC receives your P11D paperwork.
Additionally, you must file a P11D(b) form if:
- You’ve submitted any P11D forms
- You’ve paid workers’ expenditures or benefits through payroll

You must include:
