Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether HMRC’s apps and website are accessible via the One Login system.

HMRC customers currently access digital services via the GOV.UK website or via the HMRC app by logging in with their Government Gateway credentials.

HMRC will be transitioning its customers (individuals, agents and organisations) to GOV.UK One Login.

Once HMRC customers have transitioned to GOV.UK One Login they will be able to access their digital HMRC services in the same way they currently do (via the GOV.UK website or the HMRC app) using their GOV.UK One Login credential instead of Government Gateway.

More details on HMRC’s plans to transition to GOV.UK One Login can be found in HMRC’s Transformation Roadmap, published in July 2025: HMRC's Transformation Roadmap - GOV.UK
