Why It Matters

The change simplifies access to multiple government services with a single credential for new users, reducing friction and future administrative complexity, while staged migration aims to avoid disruption for current Government Gateway account holders.

Summary

GOV.UK One Login is a new unified sign-in system for HMRC and other government services that allows users to access accounts with an email address and password after proving their identity. New HMRC users who do not already have a Government Gateway account can create a GOV.UK One Login when registering for online HMRC services by following on-screen prompts. Existing Government Gateway users should continue using their 12‑digit User ID and password for now; HMRC will notify users when they can migrate to GOV.UK One Login. Eligibility and timing to switch will vary by individual, and guidance is available on GOV.UK and related videos.
