A Government Gateway ID is a 12-digit user ID that, along with a password, gives you access to the UK government's digital services. It's essential for tasks like filing corporation tax, completing your Self Assessment, and viewing your personal tax account.

However, the way we access these services is changing. While the Government Gateway is still widely used, it's gradually being replaced by a new, single sign-in system called GOV.UK One Login.

We've delved into the ins and outs of the Government Gateway ID, how the new system affects you, and what to do if you need to set one up or recover a lost one.

What is a Government Gateway ID and why is it required?

A Government Gateway ID is a way for HMRC to verify your identity when you use their services online. This 12-digit ID allows you to securely access a variety of areas on the HMRC website.

Examples of services you need it for:

• Your personal tax account
• Submitting or managing your Self Assessment tax return
• The Construction Industry Scheme (CIS)

To access these services, you'll be asked to provide your Government Gateway ID and a password. This confirms your identity to HMRC and protects the sensitive data stored in your account.

The move to GOV.UK One Login

The Government Gateway is being phased out and replaced by a new system called GOV.UK One Login. The goal is to have a single, secure way for users to access all government services.

HMRC is managing this transition in stages. Since May 2024, new users registering for HMRC services for the first time have been invited to create a GOV.UK One Login account. If you already have a Government Gateway account, you can continue to use it until you're invited to switch. HMRC plans to migrate existing individual customers to the new system between late 2026 and 2027.

Tax agents and organisations will also continue to use Government Gateway until they are invited to move to GOV.UK One Login.

How to get your Government Gateway ID

You are issued a Government Gateway ID when you first register for an HMRC online service, such as Self Assessment or VAT. Your ID would have been sent to you by email or post at the time of registration.

If you don't have one, here's how to set one up:

1. Go to the HMRC online services registration page and select the service you need.
2. You'll be taken to the sign-in page. Scroll down and select the option to 'create sign in details'.
3. Enter the email address you want to use for the account. You'll be sent a confirmation code to this address.
4. Input the confirmation code from the email.
5. Enter your full name, create a secure password, and set up a recovery word for your account.
6. Once complete, your 12-digit Government Gateway ID will be displayed on the screen and also sent to you by email. Make sure you keep a secure record of your ID and password.
7. For some services, HMRC will also post an activation code to your registered address. This can take up to 10 working days to arrive in the UK, or 21 days if you're abroad. You'll need to enter this code online to fully activate your account.

What to do if you’ve lost your Government Gateway ID

If you enter the wrong ID or password multiple times, HMRC will lock your account for two hours for security reasons. If you're unsure of your details, it's best to use the recovery service.

First, try searching your email inbox for "Government Gateway" to find the original confirmation email. If you can't find it, you can recover your details on HMRC's 'problem signing in' page.

• If you've lost your User ID: You'll need the email address you registered with to have your ID sent to you again.
• If you've lost your password: You can reset it online. You'll need to provide your Government Gateway User ID and the email address you registered with.
• If you've lost both your User ID and password: You'll need to prove your identity to HMRC to get new login details. You will need your National Insurance number and details from a valid UK passport, payslip, or P60.

It's also important to know that HMRC deactivates accounts that have not been used for three years, so you may need to re-register if it has been a while since you last logged in.

If you're still having trouble, you can contact the HMRC Self Assessment helpline on 0300 200 3310. The line is open Monday to Friday, 8am to 6pm, and is often less busy before 10am.

HMRC also offers accessible contact methods, including Relay UK for text-based calls, webchat, and a video service for British Sign Language (BSL) users.

Can I share my Government Gateway ID?

No. HMRC advises that you should never share your login information with anyone, including your accountant. These details should be treated with the same level of security as your online banking login. Your account contains sensitive personal and financial information that could be misused if it fell into the wrong hands.
