HMRC does not allow any software to submit amendments/corrections for P11d/P11d(b).
All P11D/P11D(b) amendments/corrections must be processed via your company Government Gateway account.
For guidance on correcting P11D/P11D(b) forms online, please refer to the official HMRC page, Expenses & benefits for employers. This comprehensive guide provides step-by-step instructions to help you navigate the correction process accurately.
Should you encounter any difficulties accessing the system, assistance is available from the HMRC Online Services Helpdesk at 0300 200 3600.
Amending a P11d
Amending a P11d
You must include all the benefits and expenses for the tax year - not just the ones you are changing.
HMRC Example: You submitted a P11D showing a medical benefit of £300 and a car benefit of £2,100. The car benefit is correct but the medical benefit should be £500. Submit a P11D showing both the medical benefit of £500 and the car benefit of £2,100.
The information you will need to submit your corrections is:
- Tax year
- Business name
- Business address
- Employer PAYE reference
Amending a P11d(b)
Amending a P11d(b)
When submitting an online P11D(b) correction, you must ensure to input the total amount of Class 1A National Insurance owed, rather than the difference from your prior submission.
HMRC Example: If your initial online P11D(b) indicated a £10,000 payment due for Class 1A National Insurance, and you later discover you forgot an additional £500, your revised online P11D(b) should reflect the total amount as £10,500.
The information you will need to submit your corrections is:
- Tax year
- Business name
- Business address
- Employer PAYE reference
