Appoint someone to deal with HMRC on your behalf
Overview
You can authorise someone else to deal with HM Revenue and Customs (HMRC) for you.
You can:
- authorise an agent to manage your tax affairs (such as an accountant or tax adviser)
- ask a friend or relative to manage your tax online
- authorise a friend, relative or voluntary organisation to talk to HMRC and help you fill in forms
- give someone power of attorney to make tax decisions on your behalf or help you make tax decisions
This guide is also available in Welsh (Cymraeg).
If you have to fill in a Self Assessment tax return, HMRC will send all correspondence to the person you’ve authorised - except tax bills or refunds. Otherwise, HMRC will continue to write to you.
If you just need someone to help you with your Self Assessment in the short term, call HMRC. The person who’s helping you must be with you when you call - HMRC will confirm their identity and check that you’re happy for them to represent you.
