• Agent Grant Authorisation

Your Agent Grant Authorisation / Verification of Agent Reference Number was incomplete. Please correctly enter the Agent Reference Number (ARN) and Re-Authorise

Process 1: HMRC MTD Agent Grant Authorisation
To use the Agent Authorisation Service, you need to obtain HMRC Authorisation by doing MTD Agent Grant Authorisation, which will allow our server to interact with HMRC on your behalf.

Process 2: Verification of Agent Reference Number (ARN)
You’ll need an Agent Reference Number from HMRC to complete Agent Grant Authorisation. Please carefully enter your correct Agent Reference Number (ARN) details below.

If you do not have Agent HMRC Gov Gateway Credentials or an Agent Reference Number (ARN), you must first register with HMRC as a Tax agent and apply for an ARN. Once you have obtained your Agent credentials and ARN, you can return here to proceed with the Agent Grant Authorisation process.
