How do I authorise an agent for Making Tax Digital for Income Tax?

How do I authorise an agent for Making Tax Digital for Income Tax? Your agent sends you a link from their HMRC agent services account. You sign in with your own HMRC details and accept it within 21 days. If you start MTD in April 2027, do this well before 7 August 2027. GOV.UK says the link expires after 21 days. Your agent can send you a new request from their agent services account. The ones you use for that tax service, usually the user ID and password for your Self Assessment. If you have more than one account, make sure you use the right one. If you have none, you can create them from the link. No. Authorisation lets the agent act for you. They still need to sign you up for MTD, which they can do from their agent services account once you have authorised them. Read the full answer, with every source, at rightotax.co.uk.
