Our earlier article sets out the details of a new requirement for tax advisers to register with HMRC from May 2026 which has much wider application than the description suggests. The regime will impact anyone who ‘interacts’ with HMRC in relation to the tax affairs of a client although some exceptions apply. HMRC have recently updated their guidance on this new requirement to confirm that financial services organisations within scope will not have to register until the end of the year. The guidance now states that “You’ll need to register for an agent services account from 18 May 2026, unless one of the following applies:
- if you already have a Self Assessment or Corporation Tax account, you’ll need to register from 18 August 2026
- if you only provide third-party payroll services on behalf of clients and do not interact with HMRC in any other way, you’ll need to register from 18 November 2026
- if you are a financial services organisation, you’ll need to register from 31 December 2026.”
The guidance was also updated to confirm that intermediaries for the Import One Stop Shop scheme do not need to register if this is their only interaction with HMRC. Details of how to register are still outstanding.
