The brown envelope landed on Amira’s doormat in Stockport on a Tuesday. Inside was a tax code letter she didn’t understand, and a line telling her to check it online. The same week, her husband Craig started taking cash for weekend gardening jobs and found out he’d need to register with HMRC. Two people, one kitchen table, and one question: how do you set up a Government Gateway account in 2026? The answer has changed this year, and it depends on whether you’ve ever had one before.

What a Government Gateway Account Actually Is
Amira set hers up in 2019 to claim Marriage Allowance, wrote the user ID on a Post-it, and stuck it inside a kitchen cupboard. That Post-it is the whole system in miniature. Government Gateway has been the front door to HMRC since 25 January 2001, when it was built for the old Inland Revenue and Customs and Excise. You get a user ID of up to 12 characters and a password, and that single sign-in opens your personal tax account, Self Assessment, VAT, PAYE for employers and Corporation Tax. When you create one you pick a type: Individual, Organisation or Agent. The ID is not your National Insurance number or your 10-digit UTR, a mix-up behind many cases where Government Gateway isn’t working on the first try.
The 2026 Twist: New Users Now Get GOV.UK One Login
Craig hit the twist straight away. He clicked “Create sign in details” expecting a 12-character ID and was asked for an email address and password instead. That’s GOV.UK One Login. Since 9 February 2026, new HMRC customers without a Gateway account have been set up on One Login, and HMRC’s Transformation Roadmap update of 27 July 2026 confirms that all new individual customers now go this way. If you already have a Gateway ID, nothing changes yet: HMRC says carry on using it, and it will contact existing individuals when it’s their turn, with an aim of starting in 2027. Businesses and agents are expected to move by 2030. One Login already covers more than 200 services and is the sign-in half of the wider UK digital ID story.
What to Have Ready Before You Start
The couple wasted 20 minutes hunting for paperwork, so learn from them. Put these on the table first: an email address you can open straight away, your National Insurance number, a mobile phone for security codes, and one form of ID. HMRC accepts a UK passport, a photocard driving licence, a P60 or a recent payslip to confirm who you are, and it may ask extra questions based on credit reference data, such as which company holds your mobile contract. Craig’s UTR only arrives after he registers for Self Assessment, so don’t panic if you haven’t got one. With everything to hand, sign-in set-up takes about 10 to 15 minutes. You can check your National Insurance record online once you’re in, but you need the number to get there.
Step by Step: Creating Your Sign-In Details
Here is the path for a new Gateway account, and the opening steps are the same for One Login. Go to the official HMRC sign-in page on GOV.UK and choose “Sign in”, then “Create sign in details”. Enter your email, then type in the confirmation code HMRC emails you. Give your full name. Create a password. Set a recovery word. Your user ID then appears on screen and is also emailed to you. Write it down somewhere safe at that moment. Next you choose Individual, Organisation or Agent and add services such as VAT or PAYE; some post an activation code that expires after 28 days. Lose the ID later and you’ll need to recover a lost Government Gateway user ID through the sign-in page.
Proving Who You Are
Sign-in details only get you to the gate; HMRC then wants proof you are you. For Amira that meant her name, date of birth and NI number, then her passport for the check. Craig’s One Login route looked different. GOV.UK’s guide to proving your identity lists three options: the GOV.UK One Login app, which scans a passport or driving licence and your face (iPhone 8 or Android 10 and newer); a set of online security questions about things like bank accounts and phone contracts; or a participating Post Office, where staff scan your ID and a result usually comes within a day. One Login saves that proof for other services. Craig did the app in his van and was ready to file Self Assessment online for the first time before the kettle boiled.
Choosing Your 2-Step Verification
Every sign-in asks for a fresh access code, and your choice of method matters more than most people realise. Government Gateway offers three: a text message, a voice call that reads the code aloud, or an authenticator app. One Login gives two: a text to a UK mobile number only, or an authenticator app on a phone, tablet or computer, with each code dying after 15 minutes. Amira picked text in 2019, then changed her number and locked herself out. The fix is simple: sign in, and when the code screen appears choose “You can get help” to switch methods. Pick an authenticator app if you change phones often, and keep a back-up method. The HMRC app skips most of this once set up, letting you in with a 6-digit PIN, fingerprint or face.
What You Can Do Once You’re In
Amira’s brown envelope made sense within minutes of signing in. Her personal tax account showed the tax code, the income HMRC thought she’d earned, and the tax she’d paid across the last 5 years. You can check your tax code online, claim a tax refund, check Child Benefit, see your State Pension forecast, look for gaps in your National Insurance record, manage Marriage Allowance, update your address, and find your NI number or UTR when a form demands it. HMRC’s July 2026 update says 19.7 million people used a personal tax account in 2025 to 2026, and 7.6 million used the HMRC app. Craig’s account was plainer, but it held the one thing he needed, a place to submit his first return.
Locked Out, Lost, or Suspicious?
Things go wrong, and HMRC’s rules on what happens next are clear. Type the wrong password too many times and the account locks for 2 hours, and nobody at HMRC can open it sooner. Lost your user ID or password? Start at the sign-in page and follow the recovery links, which is what Amira did when the Post-it finally fell off. For error messages, identity problems or codes that never arrive, ring the Online Services Helpdesk on 0300 200 3600, Monday to Friday, 8am to 6pm, or use the webchat on tax.service.gov.uk. One more thing: HMRC won’t text you a link asking for your Gateway details or a refund, so an HMRC text scam is the likelier explanation for any surprise message.
Where This Leaves You
By Saturday, Amira’s tax code was sorted and Craig had a One Login, a UTR on its way, and his 5 October 2026 registration deadline covered. A Government Gateway account, or its One Login replacement, is 15 minutes of effort, but it’s the key to almost everything HMRC holds about you. If you already have an ID, sign in this week, check your 2-step method still reaches a phone you own, and move that Post-it somewhere safer. If you’re new, the email-and-password route is waiting.
Frequently Asked Questions
What is a Government Gateway user ID?
It’s the sign-in name for HMRC online services, up to 12 characters long, issued when you create sign-in details. It differs from your National Insurance number and UTR.
Is a Government Gateway account free?
Yes. Creating Government Gateway or GOV.UK One Login sign-in details costs nothing, and HMRC never charges to recover a lost user ID or reset a password.
Do I need to switch to GOV.UK One Login?
Not yet. Existing Government Gateway users keep their ID until HMRC contacts them, with existing individuals expected to move from 2027. Only brand-new individual customers use One Login now.
How long does it take to set up a Government Gateway account?
About 10 to 15 minutes for the sign-in details if your passport or P60 is ready. Activation codes by post or a Post Office visit can add days.
Why is my Government Gateway account locked?
Too many wrong passwords or codes lock the account. It opens again by itself after 2 hours, and HMRC staff cannot release it early, so wait and try again.
