What Is The Government Gateway? (2026 Guide) – Find Your User ID, Set Up & Sign In to HMRC

The Government Gateway is the login system you use to reach HMRC's online services. You sign in with a 12-digit user ID and password to file Self Assessment, manage VAT, run PAYE and view your tax account. It is gradually being replaced by GOV.UK One Login but it is still how most businesses reach HMRC in 2026.

Key Highlights
  • HMRC sends a Government Gateway activation code by post within 10 working days, and the code expires after 28 days if not used.
  • Sole traders and ltd company directors need separate Government Gateway IDs for each business they operate.
  • Five failed login attempts lock your account for two hours, and further failures can lock it indefinitely.
  • Companies House WebFiling moved to GOV.UK One Login in October 2025, but HMRC services remain on Government Gateway with no confirmed migration date.
  • Your Government Gateway user ID is a 12-digit code, not your email address or UTR number.

What Is a Government Gateway User ID? (Your 12-Digit Login)

A Government Gateway User ID is a unique 12-digit identifier used alongside a password to access HMRC online services through a gateway account securely.

This ID is essential for:

  • Individuals: To access your personal tax account, view tax-free allowances, and manage tasks like Self Assessment for the current tax year.
  • Businesses: To handle VAT, Corporation Tax, or check details on a business tax account, depending on your type of account.
  • Tax Agents: To efficiently manage multiple clients’ tax affairs across HMRC’s digital services.

Your gateway user ID and password serve as your official sign-in credentials, enabling you to sign in to your gateway with confidence. You’ll also need them to prove your identity through the ID check app or photo ID, especially when setting up or accessing a new online account.

What Is a Government Gateway Account Used For?

With one Government Gateway user ID you can: file and pay Self Assessment; register for and submit VAT returns (Making Tax Digital); run PAYE and submit payroll; file Corporation Tax; check your National Insurance record and State Pension; and view your tax account, refunds and HMRC letters.

How to Find Your Government Gateway User ID?

Your Government Gateway user ID is a 12-digit number – not your email address. To find it:

  • Check the confirmation email HMRC sent when you registered – the 12-digit ID is in that email.
  • Look at any earlier HMRC letters or your saved sign-in details.
  • If you cannot find it, go to HMRC’s “Problem signing in” page, choose “I have lost my user ID”, and recover it using the email address and password you registered with.

What You Need Before You Register?

  • A personal email address (your recovery contact)
  • Your National Insurance number (for an individual account)
  • For a limited company: your Companies House number and Corporation Tax UTR
  • Any service reference you plan to enrol – for example your VAT number or PAYE reference

How to Set Up a Government Gateway Account (6 Steps)?

Yes, you must register for a Government Gateway account to access HMRC’s digital services. The process is straightforward for both individuals and businesses.

Here’s how to do it:

  1. Go to the HMRC sign-in page.
  2. Scroll to the section for new users and click ‘Create Sign-In Details’.
  3. Provide your preferred email address.
  4. Check your email inbox for a confirmation code; use this code to complete the verification on the site. Important: This email code verifies your address; do not confuse it with service-specific postal activation codes.
  5. After verification, you will be issued a unique 12-character User ID for your account.
  6. Select whether you are registering as an individual or on behalf of a company, then follow the on-screen prompts to complete setup.
  7. Your Government Gateway registration is now complete.
  8. The ID will also be sent to your registered email address. Once your account is set up, you can sign in and enrol for the tax services you need.

Individual, Organisation or Agent: Which Account Type to Choose

  1. Individual – personal tax, Self Assessment and your Personal Tax Account
  2. Organisation – a limited company, partnership or charity managing VAT, PAYE and Corporation Tax
  3. Agent – accountants or bookkeepers acting for clients

Choose Organisation for a limited company; most sole traders choose Individual.

How to Recover a Lost Government Gateway User ID or Password?

If you’ve lost your Government Gateway credentials, don’t worry. Use one of these methods to recover them:

  1. Search your emails

    When you set up your Government Gateway account, your user ID was sent to your registered email address. Search your email inbox (and any folders, including spam) using the keyword “Government Gateway user ID.” If you haven’t deleted the confirmation email, you can locate your user ID there.

  2. Use HMRC’s ‘Problem Signing In’ page

    • Click on Recover your user ID and follow the prompts.
    • Click on ‘reset your password’ to reset your password.
    • Enter the email address associated with your account, and your user ID will be sent to you. The service also allows you to recover or update a forgotten email address.

    These methods should help you regain access to your account. If you still cannot recover your credentials, consider contacting HMRC for further assistance.

  3. Call the HMRC helpline

    If you cannot remember the associated email address, you will need to call HMRC’s online service helpline. Be ready with identity verification information such as your National Insurance number, UTR number, residential and registered office address.

Four HMRC Online Tax Services on Government Gateway You Must Enrol in After Forming a Limited Company

Through your Government Gateway business account, you can manage essential tax-related tasks:

These tools are essential for efficient financial management and compliance with UK tax regulations.

Use Your Personal Tax Account to Check Income Tax, Claim Refunds, and Manage Benefit

For your personal service account, you can:

  • Check your Income Tax estimate and tax code.
  • Fill in, send, and view a personal tax return.
  • Claim a tax refund.
  • Check your Child Benefit, income from work (last 5 years), and Income Tax paid (last 5 years).
  • Manage tax credits and check your State Pension.
  • Check if you’ll benefit from and can pay voluntary National Insurance contributions.
  • Track submitted tax forms, check/update Marriage Allowance, and tell HMRC about name/address changes.
  • Check/update work benefits (company car, medical insurance).
  • Find your National Insurance number and Unique Taxpayer Reference (UTR) number.
  • Check your Simple Assessment tax bill.

Add a Tax Service to Your Account by Linking Your VAT Number, UTR, or Employer Reference

To manage a tax, duty, or scheme, go to the HMRC login page and sign in. Once logged in, navigate to the ‘Business Tax Summary’ page and select ‘Add a tax, duty, or scheme.’ You will see two options:

  1. Option 1: You are already registered for the tax (e.g., registered elsewhere but haven’t linked it to your Gateway account). You will need specific details:

    • VAT: VAT Number, Principal Place of Business postcode, Date of VAT registration, Final month of last VAT return submitted, and Amount paid to HMRC.
    • Corporation Tax: Company UTR, Principal Place of Business postcode, Company Registration Number (CRN).
    • CIS/PAYE: Employer Reference, Accounts Office Reference.
    • Self-Assessment: Personal Unique Taxpayer Reference (UTR), Postcode, National Insurance Number.
    • Note on Activation Codes: After signing up for a service, HMRC often sends an activation code by post to your registered office within 10 days. You must activate the service within 28 days, as the code will expire. Request a new code if it expires.
  2. Option 2: You have not yet registered for the tax.

    Select ‘I want to tell HMRC that I am in business and need to register for a new tax or that the company is now active.’ Follow the on-screen prompts through sections like ‘What types of business can use this service,’ ‘Types of business that cannot use this service,’ and ‘What to do next.’ Once completed, you can register for VAT, PAYE/CIS, Corporation Tax, or Self-Assessment. In some cases, HMRC may request identity verification (e.g., driving licence, mobile phone).

Create a New User ID Only After Exhausting All Recovery Options

If you have exhausted all recovery options for your existing Government Gateway User ID and cannot regain access, creating a new account is an alternative. This process involves registering for any government service that requires it, either through the HMRC website or another government portal. Be aware that creating a new ID effectively replaces your old one, and you will need to re-enrol in any previously used services as if you’re signing up for the first time. Identity verification may be required again before HMRC grants access to sensitive services under your new ID.

Five Failed Logins Lock Your Account for Two Hours

If you make five unsuccessful login attempts to your Government Gateway account, you’ll be temporarily locked out for 2 hours. During this period, you won’t be able to log in, and HMRC support will not be able to assist you.

Your account may be locked indefinitely if further failed attempts occur after the 2-hour lockout. In this case, you’ll need to contact HMRC, who will guide you through identity verification and account recovery. To avoid delays, have your identification details ready when contacting HMRC.

One Login Replaces Separate Credentials with a Single Identity Verified Once

GOV.UK One Login is already live for Companies House WebFiling and rolling out across HMRC services. You create one account, verify your identity once, and use the same credentials for every government service that adopts the platform.

Government Gateway vs GOV.UK One Login Comparison
Feature Government Gateway GOV.UK One Login What to do now
Sign-in credential 12-digit user ID and password Email address and password with two-factor authentication via smartphone Keep your 12-digit Government Gateway ID stored securely. You still need it for all HMRC services.
Identity verification Postal activation code per service, expires after 28 days One-time verification using a passport or UK driving licence. Users without photo ID must verify in person at a Post Office. Activate each Government Gateway postal code within 28 days or request a replacement. When you register for One Login, use the Post Office route if you lack photo ID.
Companies House WebFiling No longer supported since October 2025 Required for all Companies House filings Create a One Login account if you file with Companies House.
HMRC services Still required for Self Assessment, VAT, PAYE, Corporation Tax Not yet available for HMRC tax services Continue using Government Gateway for all HMRC filings.
Tax agent access Agents can access client services through their own Gateway credentials Agents cannot use One Login to act on behalf of clients. Firms must maintain both systems. If you use an accountant or tax agent, confirm they still have Government Gateway access for your filings.
Account recovery Email search, HMRC online portal, or phone (0300 200 3600) Email-based recovery with identity reverification. Some users report permanent account locks with no recovery path. Note the HMRC helpline number now. If your One Login account is locked, contact GOV.UK support directly.
Lockout policy Five failed attempts locks account for two hours. Further failures lock indefinitely. Users have reported broken links, blank screens, and valid email addresses not recognised during login. Reset your Government Gateway or One Login password on the first failed attempt rather than retrying.
Status Legacy system, no shutdown date announced by HMRC. Only new users are being directed to One Login for certain services. Rolling out department by department. Many existing users are confused about whether to switch. Use both systems in parallel until HMRC contacts you about migration. Do not switch voluntarily.

Frequently Asked Questions on Government Gateway

Is Government Gateway the same as my Personal Tax Account?

Government Gateway and your Personal Tax Account are not the same, but they are closely related. The Government Gateway is a secure login portal used to access various UK government services, including your HMRC Personal Tax Account. Your Personal Tax Account is a specific online service provided by HMRC where you can view and manage your tax records, income, and National Insurance information. You use your Government Gateway credentials (username and password) to log in to your Personal Tax Account; however, these credentials serve different purposes.

Do I need a separate Government Gateway ID for each business?

If you operate more than one business, you should create a separate Government Gateway ID for each company. This ensures each business has its distinct tax account linked to its Unique Taxpayer Reference (UTR). It helps HMRC keep your business records accurate and allows you to manage VAT returns, Corporation Tax, PAYE, and other filings independently for each entity. Maintaining separate Government Gateway accounts also simplifies authorisation, access control, and audit trails, especially if you appoint accountants or tax agents.

Do I need to switch from Government Gateway to GOV.UK One Login right now?

Use both systems in parallel until HMRC migrates your account. HMRC will contact you directly when your services move across. Do not create a One Login account to replace your existing Government Gateway.

Can I still use my Government Gateway ID if GOV.UK One Login is available?

If you already have a Government Gateway account, you continue using it for all HMRC services until HMRC migrates your account. GOV.UK One Login is currently only required for new users registering for certain services, and for Companies House WebFiling, which moved to One Login in October 2025. Do not create a new One Login account to replace your existing Government Gateway — use both systems in parallel during the transition period.

I created a GOV.UK One Login for Companies House. Will HMRC use the same account when it migrates?

HMRC has not confirmed whether your existing One Login account will carry over to HMRC services when they migrate from Government Gateway. The GOV.UK One Login system is designed as a single credential across all government departments, which suggests your Companies House account should eventually work for HMRC too. However, HMRC has not published a migration timeline or confirmed the technical process. Keep your Government Gateway credentials active until HMRC contacts you directly with instructions. Do not delete or deactivate either account during the transition period.

Will HMRC transfer my enrolled tax services automatically when Government Gateway shuts down?

HMRC has not announced how enrolled services will transfer from Government Gateway to GOV.UK One Login. The department has not confirmed whether Self Assessment, VAT, PAYE, and Corporation Tax enrolments will migrate automatically or require manual re-registration under a new One Login account. Until HMRC publishes a formal migration process, keep a record of every tax service enrolled under your current Government Gateway ID. Save your 12-digit user ID, the email address linked to your account, and your activation dates for each service. These records will simplify re-enrolment if the transfer is not automatic.

Where do I find my Government Gateway user ID?

It is the 12-digit number emailed to you when you registered. If you have lost it, use HMRC’s “Problem signing in” page and recover it with your registered email and password.

Is the Government Gateway the same as GOV.UK One Login?

No. The Government Gateway uses a 12-digit user ID; GOV.UK One Login is a newer single account (email + password + security code) that is gradually replacing it. Most HMRC services still use the Government Gateway.

Why will my Government Gateway not let me log in?

Usually a mistyped user ID or password, an account locked after five failed attempts (unlocks after two hours), or a service you have not enrolled for. Use HMRC’s “Problem signing in” page.

How much does a Government Gateway account cost?

Nothing – registering and using HMRC online services is free.
