How to authorise a UK tax adviser: form 64-8

What HMRC agent authorisation does, how it protects you, and how Matthew deals with HMRC on your behalf.

Short answer: Authorising Matthew as your tax agent (Form 64-8) allows him to speak directly to HMRC on your behalf. He handles the correspondence, resolves queries, and files your returns so you never have to sit on hold or decipher HMRC letters.

Key points

  • Form 64-8 allows Matthew to deal with HMRC directly for your tax affairs.
  • You stay in full control and approve your return before anything is submitted.
  • Stops you having to wait on hold on busy international HMRC telephone lines.
  • Authorisation can be set up in minutes using HMRC's secure online service.

What agent authorisation allows Matthew to do

When you authorise Matthew as your agent with HMRC, he can view your official tax records, check payments made, request missing information, and resolve HMRC enquiries directly.

This means when HMRC sends complex tax letters or raises questions, Matthew handles the response for you.

You always stay in complete control

Authorisation does not give an adviser power to submit returns without your approval. You always review and sign off your tax figures before any return is sent to HMRC.
