How to claim
Claim online
You’ll need to sign in with your Government Gateway user ID and password (if you do not have a user ID, you can create one when you first try to sign in).
You can make a change to your claim after you submit it, for example because you need to add another pension. If you do this you will need to provide details for all the pensions you added previously, including any new ones. This will replace your previous claim for the selected tax year only.
If you need to make changes to multiple tax years, you’ll need to do this separately for each tax year affected.
You can also remove pension details for a selected tax year but this will cancel your claim for that year.
Online claims
You’ll need to use the same Government Gateway user ID and password that you used to make your initial claim.
You can make changes to the information you submitted. You should do this as soon as possible by signing into the service and selecting the relevant option to make changes.
Claims by post
You must send us a letter with all the details you want to add or remove from your claim, for each tax year affected.
A link has been added to find out when you can expect to receive a reply from HMRC to a query or request you've made.
