If you run a UK business, work as a sole trader, employ staff or deal with HM Revenue & Customs (HMRC), you will eventually encounter Government Gateway. For years, Government Gateway has been one of the main ways individuals and businesses access HMRC's online services. It provides a user ID and password that can be used to sign in to eligible government services and manage tax-related responsibilities online.

However, the UK government is now moving towards GOV.UK One Login, which will gradually replace existing sign-in routes, including Government Gateway. Since February 2026, new individual HMRC customers without existing Government Gateway credentials have started being offered GOV.UK One Login instead. Existing Government Gateway users should continue using it until HMRC tells them to move.

That transition makes understanding Government Gateway particularly important for business owners who already have an account. This guide explains what a Government Gateway account is, what it is used for, how businesses and individuals access HMRC services, what to do if you lose your credentials and how Government Gateway differs from Companies House accounts.

What Is a Government Gateway Account?

A Government Gateway account is a set of online sign-in credentials used to access certain UK government digital services. Traditionally, this means a Government Gateway user ID and password. Depending on the service, you may then be asked for additional security information, such as a verification code sent by text message, voice call or through an authenticator app. HMRC says most of its accounts have additional protection through multi-factor authentication. For businesses, Government Gateway is particularly associated with HMRC services. You might use it to access services relating to:

• VAT;
• PAYE and employers;
• Corporation Tax;
• Self Assessment;
• Making Tax Digital;
• tax registrations;
• certain HMRC business services; and
• other online tax administration.

The exact services available depend on the account and what you have registered or enrolled for.

Is Government Gateway the same as HMRC?

No. HMRC is the government department responsible for administering taxes and certain payments. Government Gateway is a sign-in mechanism used to access government online services. A useful way to think about the relationship is:

HMRC provides the tax service; Government Gateway has historically provided the door through which many users sign in.

That distinction becomes even more important as GOV.UK One Login is introduced.

What Is a Government Gateway User ID?

A Government Gateway user ID is the identification number associated with your Government Gateway sign-in. It is traditionally a 10- to 12-digit number. It is not the same thing as:

• your company's Companies House number;
• your VAT registration number;
• your Unique Taxpayer Reference (UTR);
• your PAYE reference; or
• your National Insurance number.

These identifiers serve different purposes. For example, a UK limited company might have:

Keeping these separate can prevent a surprisingly common source of confusion when dealing with UK business administration.

What Can You Use Government Gateway For?

The services available through your sign-in depend on your circumstances and the HMRC services connected to your account.

VAT

VAT-registered businesses can use HMRC's online services to manage VAT obligations. This includes submitting VAT Returns and dealing with other VAT-related services. For businesses using Making Tax Digital for VAT, compatible accounting software generally connects to HMRC rather than relying on a person manually entering every VAT figure into the Government Gateway interface.

PAYE

Employers can use HMRC's online services for employer-related responsibilities, including PAYE administration. A business employing staff therefore may need access to relevant HMRC services even if its directors do not personally complete Self Assessment.

Corporation Tax

A limited company may need to interact with HMRC regarding Corporation Tax. The company itself is a separate legal entity, so business tax administration should not automatically be confused with the director's personal tax affairs.

Self Assessment

Individuals who are required to submit Self Assessment tax returns can use HMRC's online services to manage their personal tax responsibilities. This can include sole traders, landlords and other taxpayers who meet the relevant requirements.

Making Tax Digital

Making Tax Digital is increasingly important for businesses and individuals. MTD for VAT is already established, while MTD for Income Tax is being introduced in stages for qualifying sole traders and landlords. Government Gateway has historically been one of the sign-in routes used for HMRC's digital services, although HMRC is moving towards GOV.UK One Login.

How Do You Create a Government Gateway Account?

For existing services that still use Government Gateway, the creation process normally begins from the relevant GOV.UK or HMRC service. The exact process varies depending on the service. Government Gateway credentials are not necessarily created as one universal account that automatically gives you access to every HMRC service.

Instead, you may need to register for the particular service and then enrol or activate additional services. For example, HMRC's guidance for agents explains that an agent can create a Government Gateway user ID and then enrol for particular tax services.

Typical information you may need

Depending on the service, you could be asked for information such as:

• your name;
• email address;
• business details;
• tax reference numbers;
• company information;
• contact details; and
• information used to verify your identity or business.

The requirements vary by service, so it is better to follow the instructions for the particular HMRC service rather than assume every Government Gateway registration works identically.

Government Gateway for Businesses

One of the most important points for company owners is that a business and its director are not necessarily the same user for HMRC purposes. A limited company is a separate legal entity. Where HMRC provides a business service, the business may have its own relevant credentials or account arrangements.

For example, HMRC's guidance on money laundering supervision states that a sole proprietor can use their personal Government Gateway user ID, while a limited company should use the business's Government Gateway user ID. This distinction matters when several people work on the same company's tax affairs.

Can an Accountant Use Your Government Gateway Login?

You should not give your Government Gateway password to your accountant. This is an important security and compliance point. HMRC's current policy states that sharing HMRC sign-in details is prohibited. Instead, customers should authorise an accountant or other representative through HMRC's approved authorisation processes.

In other words: Do not give your accountant your Government Gateway credentials just because they are handling your tax affairs. The proper approach is to give them authorised access through HMRC's agent arrangements. This protects both the business and the adviser and creates a clearer record of who is authorised to act.

Government Gateway vs Companies House

These two systems are frequently confused, particularly by new company owners. They are not the same.

Companies House

Companies House is responsible for incorporating companies and maintaining the public register of companies. You use Companies House for matters such as:

• incorporating a company;
• filing confirmation statements;
• filing accounts;
• changing directors;
• changing registered office details;
• recording certain share changes; and
• maintaining statutory company information.

HMRC and Government Gateway

HMRC deals with taxation. Government Gateway has historically been one of the main authentication routes for HMRC's online services. A limited company can therefore have: Companies House account/access + HMRC account/access, without those being interchangeable. Changing your Companies House password does not change your Government Gateway credentials.

What Is the Difference Between Government Gateway and GOV.UK One Login?

This is increasingly important in 2026. Government Gateway is the established sign-in system used by many existing HMRC customers. GOV.UK One Login is the government's newer sign-in system intended to provide a more unified way of accessing government services. HMRC says GOV.UK One Login will eventually replace other sign-in routes, including Government Gateway.

From 9 February 2026, new individual customers without an existing Government Gateway account began being able to create a GOV.UK One Login for HMRC services using an email address and password instead of a 10- to 12-digit Government Gateway user ID. However, this does not mean every existing Government Gateway user should immediately create a new account. HMRC says existing users do not need to do anything differently until they are prompted to move.

Why the transition matters

If you search for "Government Gateway account" today, you may encounter instructions referring to GOV.UK One Login. That does not necessarily mean your existing Government Gateway account has stopped working. The transition is being introduced progressively. For business owners, the safest approach is to follow the sign-in option HMRC presents for the particular service you are trying to access.

What If You Forget Your Government Gateway User ID?

If you lose your Government Gateway user ID or password, don't create multiple new accounts immediately. First use HMRC's official recovery process. HMRC provides help for forgotten credentials and explains how users can recover or reset their sign-in details. Depending on your circumstances, you may need access to:

• your registered email address;
• your existing user ID;
• your password;
• your multi-factor authentication method; or
• other information used to verify your identity.

If you have forgotten your password, follow the "forgotten password" process shown when you sign in. If you have forgotten the user ID, use the recovery option provided by HMRC.

What Happens If You Enter the Wrong Details Too Many Times?

Security controls can temporarily lock you out. HMRC states that if you enter incorrect sign-in details too many times, the account will be locked for two hours. HMRC helpdesk advisers cannot manually unlock it during that period. If this happens, repeatedly trying different passwords is unlikely to help. Instead:

1. stop attempting to sign in;
2. check that you are using the correct credentials;
3. wait for the lockout period to expire;
4. use HMRC's recovery process if necessary; and
5. check whether there is a wider HMRC service issue.

What If You Change Your Phone Number?

Multi-factor authentication can involve receiving an access code through:

• text message;
• voice call; or
• an authenticator app.

HMRC says users can change how they receive access codes, including where they change their phone number. This is why keeping your security information current is important. A business owner who changes their phone, loses access to an old number or changes their authentication device should update their sign-in arrangements rather than waiting until an important tax deadline.

Government Gateway Security: What Businesses Should Know

Government Gateway credentials can provide access to sensitive financial and tax information. Treat them like banking credentials. HMRC recommends using a unique password and says multi-factor authentication provides additional protection.

Businesses should also avoid storing passwords in unsecured documents or sending them through ordinary email or messaging platforms. Most importantly, do not give your credentials to a third party simply because they claim they need them to file your tax return. HMRC's 2026 policy explicitly states that customers should authorise third parties through approved processes rather than share sign-in details.

Be particularly cautious with software

HMRC's May 2026 policy also addresses third-party software that asks customers to provide HMRC sign-in details. Businesses should be wary of any service that asks them to hand over Government Gateway credentials when an authorised integration or agent process should be used instead.

Government Gateway for Overseas Company Directors

A director or founder living outside the UK may still need to interact with HMRC if they have UK tax responsibilities. However, being an overseas director does not automatically mean you need a personal Government Gateway account. The correct arrangement depends on:

• whether you are dealing with personal or company tax;
• whether the company has UK tax obligations;
• which HMRC service you need;
• whether an accountant or tax agent is acting for you; and
• whether the relevant service now uses GOV.UK One Login.

For global founders, it is particularly important to keep Companies House compliance and HMRC compliance separate. A company can be properly registered at Companies House while still having outstanding HMRC obligations. Conversely, having an HMRC account does not mean Companies House filings have been completed.

Government Gateway FAQ

Is Government Gateway still used in 2026?

Yes. Existing Government Gateway accounts continue to be used for services that support them. However, HMRC is moving towards GOV.UK One Login, and new individual HMRC customers without existing Government Gateway credentials began using One Login from February 2026.

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

No. They are different sign-in systems. GOV.UK One Login is the newer system that the government intends eventually to use instead of existing sign-in routes, including Government Gateway.

Is Government Gateway the same as Companies House?

No. Companies House manages the UK's company register, while HMRC administers tax. Government Gateway has historically been one of the main authentication systems used to access HMRC online services.

Do limited companies need a Government Gateway account?

A limited company may need HMRC online access for services such as Corporation Tax, VAT or PAYE. The precise registration and sign-in arrangements depend on the services the company uses.

Can my accountant use my Government Gateway account?

You should not give your accountant your Government Gateway login details. HMRC requires customers to use approved authorisation arrangements when allowing agents to act on their behalf.

What is a Government Gateway user ID?

It is the sign-in identifier traditionally used with Government Gateway. It is generally a 10- to 12-digit number and is different from your company number, VAT number or UTR.

What should I do if I forget my Government Gateway password?

Use HMRC's official password recovery process. You may need your user ID, registered email address and security information, depending on the account.

Can I have more than one Government Gateway account?

Different HMRC services and circumstances can result in different account arrangements. Before creating another account, check whether the service expects you to use an existing Government Gateway ID.

Do overseas directors need Government Gateway?

Not automatically. An overseas director may need access to HMRC services depending on their personal or company tax responsibilities. The relevant service and circumstances determine what sign-in arrangement is required.

Conclusion

A Government Gateway account is essentially a way of accessing UK government online services, particularly HMRC services, using credentials that historically consisted of a user ID and password. For UK businesses, understanding the distinction between Government Gateway, HMRC and Companies House is essential. Companies House deals with corporate registration and statutory filings; HMRC deals with taxation; and Government Gateway has traditionally provided the authentication layer for many HMRC online services.

There is now an important change underway. GOV.UK One Login is gradually replacing Government Gateway, with new individual HMRC customers already being moved onto the newer system. Existing Government Gateway users should continue using their current credentials until HMRC instructs them otherwise.

For founders, directors and global entrepreneurs, the practical rule is simple: keep your HMRC access secure, do not share your login credentials with accountants or third parties, use the proper agent-authorisation process, and pay attention to which sign-in method HMRC requires for each service. Government Gateway may eventually disappear as the UK's standard government sign-in route, but understanding how it works remains important for businesses navigating HMRC today.
