An authorised agent is someone you've officially appointed to act on your behalf when dealing with HMRC. This is usually a professional accountant or tax adviser who meets HMRC’s standards and has permission to manage specific tax matters for a client.

 

What an Authorised Agent Can Do

Once authorised, an agent can:

• File tax returns (e.g. Self Assessment, VAT, Corporation Tax)

• View and manage your tax account

• Communicate directly with HMRC

• Handle CIS deductions and submissions

• Assist with investigations or compliance checks

 

Why Authorisation Matters

HMRC won’t discuss a taxpayer’s affairs with anyone unless they’ve been formally authorised. Authorisation ensures:

• Secure access to tax records

• Legal permission to act on the client’s behalf

• Clear accountability and audit trail
