HMRC

What is HMRC and what does it do?

HMRC's name reflects the department's origins. Today, its remit covers tax and customs, along with specific payment and enforcement duties.

What does the name mean, and how was HMRC formed?

HMRC stands for His Majesty's Revenue and Customs. GOV.UK styles the department's public name HM Revenue & Customs. The initials refer to a UK authority, not a tax authority for other countries.

Parliament created HMRC in 2005 as a new department replacing the Inland Revenue and Customs and Excise. This history explains why revenue and customs appear together in the name: responsibilities associated with the two former departments now sit within one UK department. GOV.UK classifies HMRC as a non-ministerial department.

Which responsibilities sit with HMRC?

HMRC's UK responsibilities include administering and collecting taxes such as Income Tax, Corporation Tax and VAT; administering National Insurance; and handling customs and excise duties. An HMRC notice might therefore concern an Income Tax bill, National Insurance or customs duty. The underlying tax or customs activity determines which service a person or business needs.

The department also administers targeted support, including Child Benefit and tax credits, and has responsibilities for certain statutory payments. A parent dealing with a Child Benefit claim is dealing with HMRC about a payment rather than a tax bill. HMRC also enforces the National Minimum Wage, but this role does not make it the authority for every employment-rights question. In the UK, employment status for tax and employment status for rights are separate questions; an HMRC tax-status view does not settle a worker's statutory rights.

Company filings also span more than one authority. A UK private limited company files its annual accounts with Companies House and its Company Tax Return with HMRC. The document being filed, rather than the broad label “company paperwork,” identifies the right authority.

When might a person or business deal with HMRC?

Employment pay, other income, running payroll, company taxes and customs each lead to different HMRC services. Identify the activity first, then choose the service.

Employees and individuals: PAYE, tax codes and support

An employee can have an HMRC matter even though the employer handles payroll. Under Pay As You Earn (PAYE), a UK employer calculates Income Tax and National Insurance deductions and reports employees' pay and deductions to HMRC. The employee does not need to operate that employer reporting process to have a question about their own tax.

For example, an employee who receives a tax-code notice can use their personal tax account to check the code and Income Tax estimate. The same service lists tasks such as claiming a tax refund and checking Child Benefit. A tax-code question concerns how employment income is taxed; a Child Benefit question concerns a targeted payment. Both can lead an individual to HMRC through a personal service.

PAYE employment alone does not require a Self Assessment return. Other income or circumstances may change that answer, so the employee should use HMRC's return eligibility guidance before assuming a return is due.

Sole traders and other Self Assessment users

Income or other circumstances may require a person to send a Self Assessment tax return to HMRC. A sole trader, or an employee with separate untaxed income, should check the current eligibility conditions instead of assuming that every side activity requires a return. An employee who starts paid freelance work, for example, has a new income question to check; their PAYE employment alone does not answer it.

Checking whether a return is needed, registering for Self Assessment if required and sending the return are distinct steps. HMRC directs people to check the need before registering. A personal tax account may provide access to registration or show return tasks, but merely opening the account does not determine the filing obligation or send a return. The eligibility result indicates the next step under the current rules.

Employers: payroll and employment tax

A UK employer using PAYE records employee pay, calculates Income Tax and National Insurance deductions, and reports the pay and deductions to HMRC through payroll. It also pays HMRC the PAYE bill, including the tax and National Insurance owed. The amount can reflect adjustments reported through an Employer Payment Summary, and eligible employers may pay quarterly; the payment is not necessarily identical each month.

A supplier invoice is a different kind of payment record. Receiving one does not itself create an employee payroll report or settle the worker's UK tax status. The actual engagement must be considered before treating someone labelled a contractor as either a payroll employee or an independent supplier.

For a business taking on its first UK employee, HMRC's employer registration guidance is the practical starting point. It explains when an employer normally registers and sets up PAYE; the business can then follow HMRC's payroll reporting instructions for that employee. This process concerns employing staff in the UK. It does not apply to every purchase of services from a contractor.

Companies: Corporation Tax, VAT, customs and Companies House

A business may encounter HMRC through several UK tax and customs activities. Corporation Tax concerns a company's tax return and payment. A company or association that receives a notice to deliver a Company Tax Return must file it even if it made a loss or owes no Corporation Tax. VAT depends on taxable activity and the applicable registration rules, while moving goods into the UK may require an import and customs declaration process. UK or cross-border business activity alone does not show which obligations apply.

For example, a non-UK seller considering UK VAT must check the facts of its transactions. HMRC's VAT registration notice addresses UK taxable supplies, place of supply and marketplace arrangements. It includes rules for non-established taxable persons making taxable sales in the UK, so the seller cannot rely on a general assumption that all overseas businesses are either registered or exempt.

A UK private limited company has two filing destinations. Its annual accounts go to Companies House, while its Company Tax Return goes to HMRC. Paying Corporation Tax is another HMRC task. Some eligible software can combine accounts and return submission in one workflow, but the obligations still have different recipients. The company's confirmation statement also goes to Companies House; it is separate from the accounts and tax return. A director told to “file with HMRC” should identify the document or payment before choosing a service.

How do HMRC online services and contact routes work?

The appropriate account or service depends on the HMRC activity and whose affairs it concerns. The app, online services and contact pages serve different purposes.

Personal, business and agent accounts

HMRC distinguishes personal, business and tax-agent online accounts. A person checking their own tax code or refund starts with personal tax services. An employer handling PAYE or a business handling VAT needs the appropriate business service. A tax agent dealing with a client's affairs uses an agent service after the appropriate authorisation. A member of the business managing its own account has a different role.

Government Gateway and GOV.UK One Login currently coexist across HMRC services. GOV.UK One Login covers some personal tax users, while HMRC tells existing Government Gateway users to continue with their existing details for the relevant service even if they have One Login for another purpose. Follow the sign-in instructions for the specific service: One Login is not a universal replacement for business or agent access.

The account categories do not put every HMRC service behind one sign-in. HMRC lists separate access points for some excise, import and export, childcare, and UK-property Capital Gains Tax services. A business that already uses its tax account for PAYE, for example, should follow the import service's sign-in guidance when it handles goods entering the UK. Its payroll account does not necessarily provide that access.

App, web service and subject-specific contact

The HMRC app supports selected personal tasks, including checking a tax code or National Insurance information, viewing Self Assessment details and payments, and managing Child Benefit. If the app does not offer a task, the HMRC page for that service identifies the appropriate online account or separate sign-in. Check the app's feature list for the specific job rather than treating it as a complete list of HMRC services.

HMRC also routes contact by subject. The official contact directory has separate entries for Self Assessment, Income Tax and PAYE, employer tax, VAT, and contact that may not be genuine. Someone with a Self Assessment question should open that subject's contact page; a business with a VAT query should use the VAT entry. Starting from the live directory provides the current contact method instead of an easily outdated generic HMRC number.

What does HMRC mean for contractor arrangements?

For UK contractor work, HMRC's concern is the tax treatment of a particular engagement. How the worker supplies the services and what happens in practice determine which question needs answering.

Tax status is a question about the actual engagement

UK employment status for tax depends on the contract and the real working arrangement. HMRC's Check Employment Status for Tax guidance asks about the parties' responsibilities, who controls the work and how payment works. A “contractor” label, an invoice or a platform used to arrange payment does not, on its own, establish the tax status.

For example, a UK client may receive invoices from a designer while also deciding what work is done and how it is carried out. Those facts need to be assessed together with the contract; the invoices alone cannot tell the client whether payroll treatment or a supplier payment route is appropriate. HMRC's CEST tool can give a tax-status view based on the facts entered. HMRC says it will stand by a result when the information remains accurate and is used in line with its guidance. The result therefore depends on the engagement being described correctly.

Employment status for statutory rights is a separate question. A CEST result about UK tax treatment does not decide the worker's rights, and a rights determination need not settle the tax answer. Each assessment uses its own applicable facts and process.

Off-payroll working rules have a narrower trigger

The UK off-payroll working rules address a particular kind of engagement: a worker supplies services through their own intermediary, such as a personal service company, and would have been an employee for tax purposes if the client had engaged them directly. HMRC's client guidance states both conditions. Describing someone as a contractor does not automatically bring the engagement into this process. An intermediary alone is not enough either; the hypothetical direct engagement must be assessed using the actual terms and working practices.

If the off-payroll rules apply, responsibility for the status decision depends on the client. Public authorities and medium or large private or voluntary-sector clients make the determination. For a small private or voluntary-sector organisation, the worker's intermediary is responsible instead. A UK business engaging someone through a personal service company should first examine how the worker supplies services, what the direct working relationship would be and which client category applies. HMRC's size and client-scope guidance includes tests beyond headcount and separate treatment for wholly overseas clients, so those cases require the detailed rules before responsibility can be assigned.

When should an earlier status view be revisited?

Revisit a UK tax-status view when a new contract or changed working practices alter the facts on which it rested. HMRC's CEST guidance asks users to check whether a change affects an earlier result. For example, a contractor who once decided when and how to complete a project might later work under the client's direction on those points. That change makes the old factual answers worth checking; it does not automatically reverse the status outcome.

For a client required to make an off-payroll determination, reassessment is part of a defined responsibility. HMRC's client guidance requires a Status Determination Statement giving the conclusion and reasons, detailed records supporting the decision, and a fresh check when a contract or working practices change. A covered client should retain the facts and reasons supporting its view so it can explain or update the determination. These client-side statement and record duties do not extend to every contractor engagement. Under the relevant rules, the worker's intermediary owns the status decision for a small private or voluntary-sector client.

How can someone use HMRC safely and through the right representative?

Who needs to act, and for which HMRC service, determines the correct authorisation. Unexpected messages should be checked through an independently opened official source before anyone responds.

Authorising an accountant or connecting tax software

Start with the role. An outside accountant handling a client's tax affairs needs an HMRC-approved agent authorisation route for the relevant service. The agent uses their own credentials; the client does not give the agent their sign-in. HMRC offers a digital authorisation process for certain listed tax services, while others have different approved routes. A company's own staff manage its tax affairs through the business account as members of the organisation, rather than being appointed as external tax agents.

Software account access is another use case. In its web-service access policy, HMRC treats a product-owned sign-in page that collects and reuses another person's HMRC web-service credentials for account access as credential sharing. In an HMRC-authorised API consent flow, the user signs in directly with HMRC and the software receives tokenised access instead of the user's credentials. Before connecting a product, a business should establish which HMRC service it seeks to access and follow that service's consent instructions.

Submitting a Self Assessment return through commercial software has its own HMRC instructions. For that filing service, HMRC tells Government Gateway users to use their existing details in the software. Some GOV.UK One Login users instead create a unique Government Gateway ID and password for the software and enter those details there; Making Tax Digital for Income Tax uses another software-authorisation process. These instructions apply to the specified return-submission service. For any filing or account connection, use the official guidance for the exact service instead of applying one credential rule to every HMRC product.

If a business is asked to connect both an accountant and a tax product, it should first ask what each will do. Agent representation, an HMRC web-service account connection and commercial-software return submission have their own official routes. The intended use determines the appropriate authorisation.

Checking an unexpected HMRC message

An unexpected text offering a tax refund is a reason to pause, even if the sender name appears to be HMRC. Do not use the message's link or number to check it. Open GOV.UK independently and consult HMRC's list of genuine contacts. The list covers recent contacts but does not include every genuine communication. An absent entry is not proof of fraud, and a familiar sender label or listed campaign does not authenticate the particular message.

To check whether the underlying tax issue is real, use the HMRC contact directory and choose the relevant subject, such as Income Tax and PAYE, instead of replying to the text. If the contact appears suspicious, follow GOV.UK's reporting instructions for that channel. The routes differ for texts, emails, app messages, calls, letters and social media. Reporting a suspected scam and checking a tax matter are separate actions; one does not establish the outcome of the other.
