The clock is ticking for employers across the UK with the 6 July P11D form deadline fast approaching. With this year’s date falling on a Sunday, it’s all the more crucial to get your paperwork sorted well in advance.
What you need to submit
For the 2024/25 tax year, employers must file two key documents with HMRC:
- Form P11D: This must be completed for each employee who received benefits in kind that haven’t been processed through your payroll system, covering everything from company cars to private medical insurance
- Form P11D(b): This calculates the total Class 1A National Insurance contributions (NICs) your company owes on all benefits in kind provided to employees – you must submit this form even if you’ve processed all benefits through your payroll system
How you should submit
HMRC now requires all P11D submissions to be made electronically. You can use HMRC’s online PAYE service if you have fewer than 500 employees or submit through compatible payroll software for larger organisations.
Key dates to remember
6 July 2025 is your triple deadline:
- Submit forms P11D and P11D(b) to HMRC
- Provide employees with copies of their benefit details
- Submit any employment-related securities returns
19 July (electronically) and 22 July (by cheque) mark the payment deadline for Class 1A NICs. Find out more on how to do this here.
Corrections and amendments
Even the most meticulous employers occasionally need to make corrections. HMRC’s system accepts only one electronic P11D submission per PAYE reference, so if you spot an error after filing, you’ll need to use HMRC’s correction service.
While HMRC hasn’t set a strict deadline for corrections, they do expect you to act swiftly once you’ve identified any mistakes. It’s worth noting that employees must receive revised copies of any amended forms, particularly as this information could be crucial for completing their personal tax returns.
Bear in mind that adjusting benefit figures may have a knock-on effect on your National Insurance obligations. You might find yourself needing to recalculate your Class 1A contributions and potentially make additional payments to square things up with HMRC.
The cost of delays
HMRC are strict when it comes to late submissions. The penalty structure is designed to encourage prompt filing:
- For late P11D(b) submissions, you’ll face £100 for every 50 employees (or part thereof) per month until the form is received, meaning even small delays can prove costly for larger employees
- Incorrect P11D forms can attract petalites of up to £3,000 per form, making accuracy as important as timeliness
Getting prepared
With the deadline approaching, now is the time to:
- Review all benefits provided to employees during 2024/25
- Gather supporting documentation
- Ensure your payroll software is up to date
- Double-check employee details and benefit calculations
- Plan your submission well before 6 July
