If you’ve over- or underreported certain benefits or expenses, you can amend your P11D submission.
Before you begin
- Make sure you include all the benefits and expenses for the tax year, not just the ones you’re trying to amend.
Example: Your original P11D listed a medical benefit of £210 and a car benefit of £4000. The correct medical benefit is actually £200. Your amended P11D should show the new medical benefit amount of £200 and the original car benefit of £4000.
- If you submitted P11Ds for a benefit outside of UK Payroll in addition to P11Ds within UK Payroll, include the values from all of the submitted P11Ds in the amended P11D.
- Remember, amending a P11D may result in an amendment to the Class 1A National Insurance due. Submit an amended P11D(b) as well to reflect the new total Class 1A National Insurance due.
How to amend your P11D submission
- Fill in the P11D and P11D(b) correction forms using your HMRC Government Gateway account.
