If you need to send an amendment you need to send the amendment on a paper form P11D - even if you submitted the original online.
Include all the expenses and benefits for the tax year, not just the ones you want to change.
To download the P11D from our website at gov.uk - search for 'P11D'
If you're reporting an amendment for a different tax year to the one on the P11D you need to write that you're using the form to correct an error made in a different year to the one printed on the form and the correct tax year on the P11D.
You also need to:
- send a covering letter explaining the reason for the change.
- send an amended P11D(b) if you need to amend their Class 1A return.
Send the form to:
P11D & P11D(b)
HM Revenue and Customs
Tell any affected employee by letter showing the amendment and giving them a new P11D marked 'REPLACEMENT'.
