If you live overseas but have UK tax affairs, contacting HM Revenue & Customs (HMRC) can sometimes feel more complicated than it needs to be. The key is knowing which HMRC service you need and using the correct overseas contact route. The good news is that you do not need to be physically in the UK to contact HMRC. Depending on your circumstances, you can use online services, webchat, telephone, post, or an authorised tax agent.

The correct route depends on whether you are dealing with Self Assessment, PAYE, VAT, Corporation Tax, National Insurance, or another tax matter. HMRC maintains separate contact channels for many of these services, and overseas telephone numbers can differ from the numbers used inside the UK. This guide explains how to contact HMRC from abroad, which numbers to use, what information to have ready, and what overseas company directors and business owners should know.

Can You Contact HMRC from Outside the UK?

Yes. HMRC provides dedicated contact arrangements for people who live outside the UK or are calling from overseas. For some services, HMRC publishes a specific international telephone number. For others, the standard UK number may be accompanied by an overseas alternative. HMRC also provides online services and digital assistance that can often be used regardless of where you are located.

This is particularly important for international founders who own or manage a UK company while living in countries such as the United States, Canada, Nigeria, India, the UAE, Australia or elsewhere. For example, a director living abroad may still need to contact HMRC about:

• Corporation Tax
• VAT
• PAYE and employee payroll
• Self Assessment
• National Insurance
• tax payments
• tax registrations
• penalties or compliance notices
• changes to personal or business information
• repayment claims

The important point is that Companies House and HMRC are separate organisations. Companies House deals primarily with company registration and statutory company information, while HMRC administers UK taxation and customs.

The Best Way to Contact HMRC from Abroad

Before calling, start with HMRC's official contact finder. It lists the relevant contact route for different taxes and services. In practice, your options are:

1. Online HMRC services
2. Digital assistant or webchat
3. International telephone numbers
4. Post
5. An authorised tax adviser or agent

For straightforward matters, online services are often the easiest starting point. If your question concerns a specific tax record or requires HMRC to verify information about you or your company, you may need to speak with an adviser.

Contact HMRC Online from Overseas

Many HMRC matters can be handled without making an international telephone call. Depending on the tax involved, you may be able to use your Personal Tax Account or Business Tax Account to view information, make changes, manage tax services and deal with certain administrative tasks.

HMRC also provides digital assistants for several services. For Self Assessment, for example, the digital assistant can help with matters including registration, filing, payments, refunds, penalties and Making Tax Digital. If it cannot resolve the issue, users may be able to transfer to webchat with an adviser when available. This can be particularly useful when you are calling from a country where international telephone charges are expensive.

When online contact makes sense

Use HMRC's online services first when you need to:

• check tax information
• manage your account
• make certain changes
• access tax records
• deal with routine administrative issues
• find guidance about a tax obligation
• check the status of certain requests

However, online services do not replace every HMRC telephone service. Some matters require an adviser or a specific HMRC department.

HMRC Phone Numbers for People Outside the UK

There is no single international HMRC telephone number for every tax issue. This is one of the most important points to understand. The number you need depends on the tax or service involved.

Self Assessment

For general Self Assessment enquiries, HMRC lists: Outside the UK: +44 161 931 9070, The current published opening hours are Monday to Friday, 8am to 6pm, excluding bank holidays. HMRC recommends having your Unique Taxpayer Reference (UTR) available when dealing with Self Assessment. This route may be relevant to UK taxpayers who have moved abroad but still have UK income or other tax obligations.

For payment-specific Self Assessment enquiries, HMRC publishes a different overseas number: +44 15 0647 6066, HMRC states that this line is for people who need help paying a Self Assessment bill and advises callers to have their UTR available.

Important distinction

A question about your tax return is not necessarily the same as a question about making a payment. Using the appropriate HMRC contact can reduce unnecessary transfers and delays.

Corporation Tax: Contacting HMRC from Abroad

If you operate a UK limited company while living overseas, Corporation Tax is likely to be one of the most important HMRC services you will deal with. For general Corporation Tax enquiries, HMRC currently lists: Outside the UK: +44 151 268 0571, The published opening hours are Monday to Friday, 8am to 6pm, excluding bank holidays.

You should have the company's 10-digit Unique Taxpayer Reference (UTR) available. The Corporation Tax helpline can help with general enquiries involving matters such as accounting periods, Corporation Tax payments, repayments and changes to business details. HMRC also directs businesses towards the Business Tax Account and digital assistant for some questions.

Example: an overseas company director

Imagine a Nigerian entrepreneur owns a UK private limited company but lives permanently in Abuja. The company has a UK Corporation Tax liability and the director needs clarification about a payment that does not appear correctly on the company's HMRC account.

The director does not need to travel to Britain to resolve the matter. They can use the company's online tax services or contact HMRC using the overseas Corporation Tax telephone route, provided they can pass HMRC's security checks. This is one reason keeping the company's UTR, accounting records and HMRC correspondence organised is so important.

VAT: Contacting HMRC from Outside the UK

VAT-registered businesses may also need to contact HMRC from overseas. VAT enquiries can cover:

• VAT registration
• VAT returns
• VAT payments
• VAT repayments
• VAT invoices
• VAT accounting
• Making Tax Digital for VAT
• overseas business VAT matters

Because VAT has several specialised contact routes, businesses should use HMRC's official contact finder rather than relying on an old telephone number found elsewhere online. For example, HMRC publishes a dedicated route for VAT overseas repayments for non-UK businesses. The listed overseas number is +44 (0)300 322 9279, with opening hours Monday to Friday, 8:30am to 4pm, excluding bank holidays. The important lesson is simple: do not assume the telephone number for one VAT issue is the correct number for another.

PAYE and National Insurance from Abroad

If your UK company employs people, you may need to contact HMRC about PAYE (Pay As You Earn) and National Insurance. An overseas director or employer may need assistance with:

• PAYE registration
• payroll submissions
• employee tax codes
• PAYE payments
• National Insurance
• payroll corrections
• employer reporting

HMRC provides different contact routes for different PAYE situations, so use its official contact finder to identify the appropriate service. If you are an accountant or tax adviser acting on behalf of a client, HMRC also provides dedicated agent services. For authorised agents dealing with Self Assessment or PAYE for individuals, HMRC currently lists an agent telephone line at 0300 200 3311.

The distinction between a taxpayer contacting HMRC directly and an authorised agent acting for that taxpayer matters. HMRC will not necessarily disclose confidential information to someone who has not been properly authorised.

What Information Should You Have Before Calling HMRC?

Calling HMRC from abroad without the necessary information can turn a simple question into a frustrating process. Before calling, prepare a short information pack.

For an individual

Depending on the service, you may need:

• full name
• date of birth
• current address
• National Insurance number
• Unique Taxpayer Reference
• previous UK address
• details of the relevant tax return
• HMRC correspondence
• payment information

HMRC may ask security questions before discussing confidential information.

For a company

Have the following available:

• company name
• company registration number
• Corporation Tax UTR
• VAT registration number, if applicable
• PAYE reference, if applicable
• registered office address
• accounting period dates
• relevant HMRC correspondence
• details of recent payments or returns

Do not assume that knowing the company registration number is enough. Companies House information and HMRC tax records are different systems.

Can Someone Else Contact HMRC for You?

Yes, in appropriate circumstances. A business owner living overseas may appoint an accountant, tax adviser or other professional to act as an authorised agent. This can be particularly useful if:

• you are unfamiliar with UK tax administration
• you have multiple tax obligations
• you are dealing with a penalty
• HMRC is conducting an enquiry
• you need help with Corporation Tax or VAT
• you have difficulty communicating with HMRC during UK business hours
• you manage a UK company from another country

However, an agent's authority has limits. HMRC has formal procedures governing what an agent can discuss and manage on behalf of a taxpayer. For international founders, appointing an appropriate UK tax professional can therefore be more than a convenience; it can help maintain continuity when the director is several time zones away.

What If You Need to Write to HMRC?

Telephone contact is not always appropriate. Some matters are better handled in writing, particularly when you need to provide supporting documentation or create a clear record of your position. HMRC publishes specific postal addresses depending on the tax service. For example, general Corporation Tax correspondence can be sent to:

Corporation Tax Services
HM Revenue and Customs
BX9 1AX
United Kingdom

HMRC advises businesses to include the Corporation Tax UTR and to use the address shown on a particular HMRC letter when responding to that letter. For Self Assessment, HMRC publishes:

Self Assessment
HM Revenue and Customs
BX9 1AS
United Kingdom

Always check the latest GOV.UK guidance before posting important documents because HMRC addresses and contact arrangements can change.

What If You Are Calling HMRC About a UK Company You Own?

This is common among international founders. A company can be incorporated in the UK even when its shareholders or directors live overseas. But incorporation does not remove the company's UK filing and tax responsibilities. An overseas founder should keep separate records for:

• Companies House filings
• HMRC tax registrations
• Corporation Tax returns
• VAT returns
• PAYE reporting
• business bank payments
• accounting records
• correspondence with advisers

A common mistake is to treat Companies House as the central place for everything relating to a UK company. It is not. Companies House and HMRC have different responsibilities, and a change made at one organisation does not automatically mean every relevant tax record has been updated.

How to Avoid Problems When Contacting HMRC from Abroad

1. Use GOV.UK rather than an old phone number

HMRC contact details can change. The safest approach is to start from the official HMRC contact finder.

2. Identify the tax before contacting HMRC

Ask yourself: Is this about Corporation Tax, VAT, PAYE, Self Assessment, National Insurance, or something else? That usually determines the correct department.

3. Keep your reference numbers accessible

UTRs, VAT numbers, PAYE references and other identifiers help HMRC locate the correct record.

4. Keep evidence of important communications

Record:

• date of contact
• department contacted
• name or reference of the adviser where available
• issue discussed
• advice received
• documents submitted
• expected response date

This becomes especially valuable when dealing with penalties, payment disputes or compliance issues.

5. Allow for time-zone differences

HMRC's published opening hours are UK time. If you live in Africa, Asia, North America or another region, check the UK time before calling.

Be Careful About HMRC Scams

International business owners should also be alert to fraudulent calls and messages pretending to come from HMRC. Do not assume that a caller is genuine simply because they know your name, company name or some tax information. If you receive an unexpected call claiming to be from HMRC, verify the contact independently through GOV.UK rather than relying solely on the number provided by the caller.

HMRC publishes guidance for checking whether a telephone call is genuine and provides information about suspicious contacts. Never provide banking passwords, authentication codes or other sensitive credentials simply because someone claims to be an HMRC employee.

What If HMRC Is Not Responding?

If you have already contacted HMRC, do not automatically send the same request repeatedly. HMRC provides online tools that allow taxpayers to check when they can expect a response to certain queries. If the expected response period has passed, follow the relevant HMRC escalation or complaints process. For serious tax matters, particularly where a deadline or penalty is involved, consider obtaining professional tax advice rather than simply waiting indefinitely.

Frequently Asked Questions

Can I contact HMRC online from abroad?

Yes. Many HMRC services can be accessed online through personal or business tax accounts, digital assistants and, where available, webchat.

Can an overseas company director contact HMRC?

Yes. A director living outside the UK can contact HMRC about the UK company's tax affairs, subject to HMRC's identity and security checks.

Can I contact HMRC by post from overseas?

Yes. HMRC maintains postal routes for different tax departments. Use the current GOV.UK guidance or the address provided on the HMRC letter you are responding to.

Final Thoughts

Living outside the UK does not prevent you from managing UK tax affairs. The real challenge is usually knowing which HMRC department to contact and which channel to use. For individuals, that may mean Self Assessment or PAYE. For international founders, it may involve Corporation Tax, VAT, PAYE and other business obligations. Each can have different contact arrangements.

The safest approach is to start with the official HMRC contact finder, identify the specific tax issue, gather your reference numbers and supporting documents, and then use the appropriate online, telephone or postal route. For overseas directors and global founders, good tax administration is largely about preparation. Keep your UK company records, HMRC references, correspondence and payment information organised, and do not wait until a filing deadline or penalty has become urgent before establishing how you will communicate with HMRC.

For businesses using a UK company formation and management platform such as IncorpUK, understanding the distinction between Companies House administration and HMRC tax administration is equally important. The two systems work alongside each other, but they serve different purposes—and knowing where to take a problem can save considerable time and unnecessary expense.
