Authorise someone to deal with HMRC for you

You can arrange for an ‘intermediary’ to deal with HMRC for you. This could be a friend, relative or a voluntary organisation.

You might do this if you’re ill, have a disability or do not speak English.

An intermediary can:

  • talk to HMRC and answer any questions on your behalf
  • help you to fill in forms

An intermediary will not have access to your tax online.

To authorise an intermediary to help deal with your tax, write to HMRC.

National Insurance contributions and Employers Office

The letter must include:

  • your name and address
  • your date of birth
  • your tax reference number, for example your Unique Taxpayer Reference (UTR)
  • the name and address of the person or organisation you want to authorise
  • your signature

If you cannot sign the letter, you’ll need to contact the relevant department at HMRC or get someone to do it for you.
