The deadline for filing the 2024-2025 P11D form is 6 July 2025.
As we near the end of June, you need to make sure that you file in time.
Penalties will hit from the moment the deadline is missed and includes a monthly fine of £100 for every 50 employees.
Do I need to file a P11D?
As the P11D form reports benefits given by employers, it needs to be filed in any instance where benefits have been allocated.
The P11D is an annual requirement and must be filed for each member of staff who receives taxable benefits and expenses.
If you provide company cars, interest-free loans, private healthcare schemes, and certain other benefits, these must all be declared in the P11D form.
The P11D form provides the data that is used by HM Revenue and Customs (HMRC) to calculate the correct amount of Class 1A National Insurance Contributions (NICs) that are owed by employers.
You do not want to be found underpaying your employer NICs, as this will result in further trouble and heavier fines.
To ensure that NICs can be paid by 22 July, P11D forms need to be submitted by 6 July following the previous tax year.
How to not get caught out by your P11D filings
For the time being, P11D filings are an essential part of doing business.
This is set to change in 2027 when Benefits in Kind (BIK) will need to be payrolled instead.
However, that does mean there is one more P11D form to file in 2026, so planning ahead will prevent a panic next year.
Good record keeping will allow for an easier collation of data required to fill out the P11D and will continue to be useful when the P11D is a distant memory.
Seeking professional advice remains the best way to stay on top of all your financial filings so that you can avoid penalties and stay compliant.
For now, focus on getting this year’s P11D submitted before 6 July and ask for help if you need it!
