HMRC Is Changing How You Log In — Here's What You Need to Know
If you've ever had to hunt through old emails trying to find your Government Gateway ID, you'll be pleased to hear that HMRC is finally modernising the way people access its digital services.
From 9 February 2026, new HMRC users will no longer need to register with a 10-12 digit Government Gateway ID. Instead, they'll sign up using GOV.UK One Login — a simpler system based on just an email address and password. It's a small change on paper, but for anyone who has struggled with the old system, it's a welcome one.
What is GOV.UK One Login?
GOV.UK One Login is the government's plan to create a single, unified login for all government services online. Rather than having separate accounts and login details for HMRC, Companies House, passport applications, and everything else, the idea is that eventually one login covers it all.
HMRC joining the system brings the total number of services accessible through GOV.UK One Login to over 200. The long-term vision is that you prove your identity once and can reuse it across every government service — saving time and reducing the headache of managing multiple accounts.
Does this affect you right now?
That depends on where you're starting from. Here's a straightforward breakdown:
If you're new to HMRC's digital services and don't yet have a Government Gateway account, you'll now register using GOV.UK One Login from the outset. No Government Gateway ID required.
If you already have a Government Gateway account, nothing changes for now. You don't need to do anything. HMRC will contact you directly when it's time for you to make the switch, and the rollout will be gradual and phased.
If you already have a GOV.UK One Login that you use for a different government service — such as managing your state pension or accessing Companies House — you might assume you can use it for HMRC too. Not yet. For the time being, existing HMRC users still need to use their Government Gateway to access HMRC services specifically. The two systems haven't been fully joined up yet, but that's the direction of travel.
What does this mean in practice?
For most people with existing accounts, the honest answer is: not much changes right now. HMRC is being careful about the rollout and wants to make sure it works properly before moving everyone across. That's sensible.
Where it will make a real difference is for anyone registering for HMRC services for the first time — new businesses, people filing Self Assessment for the first time, or employees accessing personal tax accounts. The process will be simpler and more straightforward than it has been.
