We will use this information to access your tax information with HMRC and to produce the HMRC 64-8 ‘Authorising your agent’ form. We will send this to you to sign and send to HMRC so we can talk to them about your tax matters. HMRC will only accept live-signed 64-8 forms so we will prepare one and send it to you electronically and ask you to print, sign and post it back to us or to HMRC directly.
