With the tax year now behind us, many employers are turning their attention to the forms and paperwork that still need to be completed. One important document on the list is the P11D — but what exactly is it, who needs to complete one, and when? Here’s a simple breakdown, plus how THL Accountancy can make the whole process easy and stress-free.
What is a P11D?
A P11D is a form that employers must submit to HMRC to report benefits and expenses provided to employees and directors that aren’t put through payroll. These can include things like:
- Company cars
- Private medical insurance
- Interest-free or low-interest loans
- Relocation expenses
- Other perks or “benefits in kind”
Essentially, if an employee or director receives something that isn’t strictly salary but has a monetary value, it often needs to be reported on a P11D.
Who Needs to Complete a P11D?
Employers — not employees — are responsible for submitting P11D forms. If you’ve provided any taxable benefits to your employees or directors during the tax year, you’ll likely need to complete and submit a P11D for each individual who received benefits.
Even if you’ve already settled the tax on certain benefits through a PAYE Settlement Agreement (PSA), you may still need to report other benefits separately on a P11D. In addition, employers must also submit a P11D(b) form, which is used to confirm the total amount of Class 1A National Insurance due on all the expenses and benefits reported.
Key Filing Dates for P11Ds
Here’s what you need to know about deadlines:
- 6th July following the end of the tax year (which runs from 6th April to 5th April):
Final date to file P11D and P11D(b) forms with HMRC and provide copies to employees. - 22nd July (or 19th July if paying by post):
Deadline for paying any Class 1A National Insurance owed.
Missing these deadlines can result in penalties from HMRC, so it’s important to stay on top of the process!
