What is a Government Gateway user ID?
A Government Gateway user ID is a unique sign-in identifier, up to 12 characters long, used with a password to access HMRC and certain other UK government online services.
It helps identify the account you use for services such as Self Assessment, Corporation Tax, VAT and PAYE. You may also need to complete an additional security check when signing in.
Government Gateway is gradually being replaced by GOV.UK One Login, but existing Government Gateway credentials remain valid for services that still use them.
Government Gateway user ID explained
Your Government Gateway credentials allow HMRC to recognise your online account and help protect sensitive tax information.
Your unique identifier
Your Government Gateway user ID contains up to 12 characters. It is separate from your National Insurance number, UTR and Companies House authentication code.
Secure account access
You sign in with your user ID and password, with additional verification where required. Keep your credentials private.
Access tax services
Government Gateway is still used for various HMRC services, although GOV.UK One Login is being introduced progressively.
Where do I find my Government Gateway user ID?
If you already have a Government Gateway account, the first place to look is the email address you used when registering.
Search your email inbox
Search for "Government Gateway", "user ID" or registration confirmation. Check archived emails and junk folders as well.
Check your saved login details
Look in your password manager or any secure record where you stored the user ID when you first registered.
Use the official recovery process
If you cannot find your ID, visit HMRC's sign-in page and follow the forgotten user ID instructions. The verification steps depend on your account.
Forgotten your Government Gateway user ID?
If you've lost your Government Gateway user ID, you may be able to recover it without creating another account.
If you've forgotten your user ID
- Check the email account originally used to register.
- Open the official HMRC sign-in service.
- Select the forgotten user ID option when available.
- Complete the identity and security checks requested.
If you've forgotten your password
- Open the relevant Government Gateway sign-in page.
- Select the forgotten password option.
- Provide your registered details and verification information.
- Create a new password when instructed.
For official instructions, see HMRC help with signing in.

Government Gateway vs GOV.UK One Login
Both systems provide secure access to government services, but they use different sign-in details and are not interchangeable for every service.
| Feature | Government Gateway | GOV.UK One Login |
|---|---|---|
| Sign-in identifier | User ID of up to 12 characters | Email address |
| Password | Yes | Yes, or other supported sign-in methods |
| HMRC services | Existing supported services | Services enabled for One Login |
| New registrations | Still used where required | Being introduced to new users |
| Future position | Being phased out over time | Intended replacement |
| Existing users | Continue using it until instructed otherwise | Use where the relevant service supports it |

What can you use a Government Gateway user ID for?
Depending on your account type and the services you have registered for, Government Gateway credentials may be used for:
Self Assessment
Access supported Self Assessment services, manage returns and review tax information.
Corporation Tax
Access business tax services and manage relevant Corporation Tax obligations.
VAT
Access VAT services and authorise compatible Making Tax Digital software.
PAYE for employers
Manage employer-related HMRC online services and payroll tax information.
Business tax account
View tax services linked to your business and manage available online functions.
Tax agent services
Authorised agents may use relevant Government Gateway and agent account credentials.
Not every service uses the same sign-in route. Some government services require separate accounts, and access may depend on whether a tax service has been added to your account.
Common Government Gateway login problems
These are some of the most common access issues and the appropriate next steps.
| Problem | Recommended action |
|---|---|

| Lost access to phone | Follow HMRC's access code recovery instructions to change your verification method. |
| Account locked | HMRC states that accounts locked after repeated incorrect attempts unlock after two hours. |
| Tax service missing | Check whether the service is linked to the correct account and whether enrolment is required. |
| Multiple accounts | Identify which account is linked to the relevant tax service before registering again. |

Is a Government Gateway user ID the same as a UTR?
No. Your Government Gateway user ID identifies your sign-in account. Your Unique Taxpayer Reference (UTR) identifies you or your business for particular tax purposes.
Government Gateway user ID
Used to sign in to supported government online services. It is a login credential rather than a tax reference number.
Unique Taxpayer Reference (UTR)
A 10-digit tax reference used by HMRC, including for Self Assessment and Corporation Tax records.
How to get a UTR number →A Government Gateway user ID is also different from a National Insurance number, a PAYE employer reference and a Companies House authentication code. Each serves a separate purpose.
Government Gateway user ID FAQs
Quick answers to common questions about finding, using and recovering Government Gateway credentials.
What is a Government Gateway user ID?
It is a unique sign-in identifier of up to 12 characters used with a password to access HMRC and certain other government online services.
How do I find my Government Gateway user ID?
Search the email address you used when creating the account, check your password manager, or use the forgotten user ID option through the official government sign-in service.
Is a Government Gateway user ID always 12 digits?
No. HMRC currently describes Government Gateway user IDs as having up to 12 characters. Do not assume that every ID must contain exactly 12 digits.
Can I recover my Government Gateway ID without my email?
Recovery can be more difficult if you cannot access your registered email address. Follow the recovery instructions for your service and contact the relevant official support team if necessary.
Is Government Gateway being replaced?
Yes. GOV.UK One Login is gradually replacing older government sign-in methods, including Government Gateway. Existing HMRC users should continue with their current credentials until directed to change.
Can I use GOV.UK One Login instead of Government Gateway?
Only where the relevant service supports it. Having a GOV.UK One Login for one government service does not automatically mean you can use it for every HMRC service.
Do I need a Government Gateway ID to file a tax return?
You need an accepted sign-in method to file through HMRC's online Self Assessment service. Depending on your circumstances, this may be Government Gateway or GOV.UK One Login. An authorised accountant may also file on your behalf using appropriate agent access.
Can my accountant use my Government Gateway login?
Your accountant should normally use the appropriate HMRC agent authorisation process rather than sharing your personal password and security codes. Authorisation allows an accountant to deal with permitted tax matters on your behalf.
Can I have more than one Government Gateway account?
It is possible to have multiple accounts, but this can cause confusion if different tax services are linked to different credentials. Check which account holds the relevant service before creating another.
What should I do if my Government Gateway account is locked?
HMRC says an account locked after too many incorrect sign-in attempts normally unlocks after two hours. If the problem persists, follow the official sign-in help guidance.
