Do I Need to Tell HMRC If I Change Address?

Relocating to a new home can be an exciting and transformative experience. Whether it’s moving across town, to a different city, or even abroad, a change of address comes with a long checklist — forwarding mail, updating utility accounts, and informing important institutions. Among these institutions, one of the most critical is Her Majesty’s Revenue and Customs (HMRC). But do you actually need to tell HMRC if you change address? The short answer is yes — and not doing so can result in serious consequences, including missed tax refunds, penalties, or even identity theft risks.

In this comprehensive guide, we’ll explore everything you need to know about informing HMRC of your address change, who specifically must do it, the correct procedures, and what happens if you fail to act. Let’s dive in.

Why You Must Inform HMRC About Your New Address

When you move, notifying HMRC is not just good practice — it’s a legal obligation in many cases. HMRC is responsible for managing your tax affairs in the UK, including income tax, National Insurance, self-assessment, benefits, and more. Your address is central to how they communicate with you and process your information.

Legal Requirement to Keep Your Records Up to Date

The UK tax system operates on a self-assessment model for many taxpayers. That means individuals are required to report changes to their personal circumstances — including address changes — to ensure accurate tax calculations and communications. According to HMRC guidelines:

• Self-employed individuals must update their address in their self-assessment records.
• Company directors are legally required to inform Companies House, which in turn informs HMRC.
• Company representatives (like agents or accountants) must ensure the business address on file is current.

Failing to do so could lead to HMRC deeming your records as non-compliant, potentially triggering investigations or financial penalties.

Risks of Not Updating Your Address with HMRC

Ignoring this step might seem harmless, especially in our increasingly digital world, but the consequences can be severe:

1. Missed Communications
HMRC uses your registered address to send critical documents. These include self-assessment tax returns, payment reminders, tax credit decisions, confirmation statements, or correspondence regarding inquiries into your tax status. If these are sent to an old address and go unseen, you could face late payments or missed deadlines.

2. Incorrect Tax Assessments
Your address can sometimes be linked to regional benefits, local taxes, or eligibility for certain relief schemes (e.g., Marriage Allowance, Universal Credit, or Local Housing Allowance). An outdated address could result in incorrect calculations or loss of entitlement.

3. Risk of Identity Theft or Fraud
If HMRC continues sending sensitive tax information to an address you no longer occupy, it could fall into the wrong hands. A former tenant or neighbor receiving your tax documents might inadvertently (or intentionally) misuse the data, leading to fraud.

4. Payment Delays or Refund Issues
If you’re due a tax refund, HMRC will send it by cheque to your registered address. Without an update, the refund may be returned, delayed, or lost. Even with direct bank deposits, a missing or incorrect address can trigger verification processes that slow things down.

Who Needs to Inform HMRC About an Address Change?

Not everyone has the same responsibilities when it comes to informing HMRC. Your obligation depends on your tax status and involvement with the UK tax system. Here’s a breakdown:

Self-Employed Individuals

If you run your own business or work as a sole trader, you are responsible for reporting to HMRC for Self Assessment. This means you must notify HMRC of your new address via your online tax account. You’ll need to update not only your personal address but also your business address if your operations are home-based or if you have a registered business location.

How Self-Employed People Can Update Their Address

1. Sign in to your Government Gateway account.
2. Go to ‘Self Assessment’ and select ‘Update your details’.
3. Choose ‘Change your address’ and enter your new information.
4. Submit your changes — confirmation will be sent to your updated email address.

Note: If you don’t have a Government Gateway account, you’ll need to register for one first.

Company Directors and Business Owners

Company directors are required to inform Companies House of address changes — and HMRC automatically receives this information. However, it’s still good practice to double-check that the update has been reflected in your HMRC records.

Businesses with a Corporation Tax reference also need to inform HMRC directly if their registered office changes. This includes Limited Companies and LLPs.

Updating Company Address via Companies House

You can file a confirmation statement (formerly an annual return) or submit a change of director or company details form (Form CH01 or AD01). Once processed, Companies House will notify HMRC, usually within a few days.

Employees and PAYE Taxpayers

Employees on a PAYE (Pay As You Earn) scheme do not typically need to inform HMRC directly if they move. Your employer handles tax code changes and reporting via your monthly payroll submissions. However, it is essential to:

• Tell your employer about your address change so they can keep their records accurate.
• Ensure your P60 and P45 forms reflect your new address.
• Update your address if you claim tax relief on expenses (e.g., working from home).

If HMRC needs to send you a tax calculation or refund, they rely on information provided by your employer, so miscommunication could still lead to delays.

Self-Assessment Taxpayers (Non-Self-Employed)

Not all people who file a Self Assessment tax return are self-employed. Others include landlords, higher-rate taxpayers, or those with foreign income or capital gains. Regardless of your reason for filing, if you’re registered for Self Assessment, you must update your address in your HMRC online account.

Failure to do so can result in missed tax return deadlines or delayed processing of submissions.

Recipients of Benefits or Tax Credits

If you receive Universal Credit, Child Benefit, Pension Credit, Working Tax Credit, or any other HMRC-managed benefit, it’s essential that you inform HMRC of your move. Changes in location may affect your payment amount — especially if housing costs or local benefits vary by region.

For example:

You can update your address through your online benefits account or by calling the HMRC helpline for the specific benefit you’re receiving.

How to Tell HMRC You’ve Moved

The process for updating your address depends on your role in the tax system. Below are the different methods:

Online via Your Personal Tax Account

The fastest and most convenient way is through your Government Gateway account. Here’s how:

1. Go to the HMRC online services portal and sign in.
2. Navigate to ‘Your profile and settings’ or ‘Personal details’.
3. Select ‘Change your address’ and enter your new address.
4. Confirm the details and save the changes.
5. You may receive a confirmation email or letter (sent to your old or new address for verification).

Note: If you’ve recently moved, ensure your email address on file is still active — otherwise, you may miss confirmation messages or vital updates.

Via Telephone

For those without internet access or facing technical issues, HMRC offers a helpline for address updates. However, it typically takes longer and may require verification through security questions.

Contact the following HMRC departments based on your situation:

• Self Assessment: 0300 200 3310
• PAYE for employees: 0300 200 3296
• Universal Credit and benefits: 0800 328 5644

Be prepared with your National Insurance number, date of birth, previous and new addresses, and other personal details to verify your identity.

By Post

While less commonly used, you can update your address by sending a signed letter to HMRC. Include:

• Full name and date of birth
• National Insurance number
• Previous and new addresses
• Reason for the change (if relevant)
• Any reference numbers (UTR, PAYE, etc.)

Send your letter to the appropriate HMRC office based on your tax type. For example:

Self Assessment Address:
HM Revenue and Customs
Self Assessment
BX9 1AS
United Kingdom

Note: Updates by post can take several weeks to process and are not recommended unless absolutely necessary.

Through Your Accountant or Agent

If you appoint someone to manage your tax affairs (such as an accountant or tax advisor), they can update your address on your behalf. They must act through their agent services account in HMRC’s portal. Ensure you’ve granted them permission through the Government Gateway.

When Should You Inform HMRC of Your Address Change?

Timing is everything. You should update your address:

• Immediately after the move, ideally before you leave your old home.
• At least within 30 days of your change of residence.
• Before key tax-related events, such as filing your Self Assessment tax return (due by 31 January each year).
• If you receive a letter from HMRC indicating a review, audit, or upcoming deadline.

Delaying the update increases the risk of falling out of compliance. For example, if HMRC sends a tax inquiry to your old address and it goes unanswered, they may assume you’re avoiding contact — triggering further scrutiny.

Special Considerations: Moving Abroad or Temporarily

Moving Permanently Overseas

If you’re relocating abroad, your tax obligations may change significantly. You may need to:

• Inform HMRC that you’re leaving the UK tax system.
• Complete a P85 form to claim tax relief or settle outstanding tax liabilities.
• Update your address to a non-UK one and provide details like your new country of residency.
• Declare whether you intend to return, as this affects your domicile status.

Even if you no longer reside in the UK, HMRC may still need to contact you for final tax assessments, especially if you have UK property income or investments.

Temporary Moves or Second Homes

If you’re moving temporarily — for example, renting a flat while renovating your primary home, or staying with family during a transition — you should still consider whether your tax affairs are affected.

For most tax purposes, your main residence is what matters. If your permanent address hasn’t changed, you likely don’t need to update HMRC. However, if you’re self-employed and operating from a temporary location, or if your business correspondence address changes, inform HMRC accordingly.

Common Mistakes When Updating Your Address

Even small errors can delay processing or cause complications. Avoid these common pitfalls:

Using Incomplete or Incorrect Address Details

Ensure your address uses the correct formatting:

• Include full postcode
• List flat or apartment number, if applicable
• Avoid abbreviations (‘St’ instead of ‘Street’, etc.)

HMRC uses third-party databases to verify addresses, so discrepancies may cause your update to be rejected.

Forgetting to Update Multiple Accounts

You might have several HMRC-linked accounts: Self Assessment, Corporation Tax, VAT, PAYE for employees, etc. Changing your address in one place doesn’t automatically update it across all systems. Be sure to check each account.

Not Informing Other Departments

HMRC isn’t the only organization you need to notify. Others include:

• Your bank and credit providers
• Your GP and local council
• DVLA (Driver and Vehicle Licensing Agency)
• Your employer
• Electoral register

A coordinated approach ensures your entire records ecosystem stays in sync.

What Happens After You Update Your Address?

Once HMRC processes your change:

• Your new address will appear on all future correspondence.
• Any pending refunds or letters will be mailed to your updated location.
• In some cases, HMRC may send a confirmation letter or email to verify the change.
• You might receive updated tax codes or forms based on your new circumstances.

It’s wise to regularly check your online HMRC account to ensure the information is correct. If you notice errors, correct them immediately.

Real-Life Scenarios: When Address Updates Matter

Let’s look at a few hypothetical but realistic cases showing the importance of updating HMRC:

Case 1: Missed Tax Refund

Sarah, a freelance graphic designer, moved from Leeds to Bristol without updating her HMRC account. A few months later, she was due a £647 tax refund. HMRC sent a cheque to her old flat. The new tenant opened it, assumed it was junk, and discarded it. It took Sarah three months and multiple phone calls to recover the funds.

Lesson: Update your address before you move, especially if you’re expecting a refund.

Case 2: Self-Assessment Deadline Missed

Raj, a landlord with two rental properties, relocated to Scotland. Because HMRC continued mailing notices to his English address, he missed the Self Assessment deadline. He incurred a £100 penalty, even though he had already prepared his return.

Lesson: Digital access is great, but HMRC still relies on physical mailing for certain reminders.

Case 3: Benefit Entitlement Reduced Due to Incorrect Location

Lucy moved from a low-rent area in Northern England to high-cost London. However, because she hadn’t updated her Universal Credit account, the housing cost portion of her benefit remained calculated for her former area, leaving her short £300 monthly.

Lesson: Moving to a more expensive region without notifying HMRC can directly impact your financial support.

Conclusion: Make HMRC Notification Part of Your Moving Checklist

A change of address is more than just redirecting your mail — it’s about maintaining continuity, compliance, and security within the UK’s tax framework. Whether you’re self-employed, a company director, a benefits recipient, or a salaried employee with additional tax responsibilities, informing HMRC is non-negotiable.

The process is quick, simple, and often free when done online. But the cost of neglecting it — in time, money, and peace of mind — can be substantial.

So, the next time you move, be sure to place “Update HMRC address” at the top of your relocation to-do list. It’s not just good administrative practice — it’s a smart financial safeguard that keeps you compliant, informed, and in control of your tax affairs.

Why is it important to inform HMRC when I change my address?

Informing HMRC of your new address is essential to ensure you continue receiving important tax-related correspondence. This includes tax returns, Self Assessment notices, tax credits decisions, and letters about benefits or pensions. If HMRC continues to send documents to your old address, you may miss critical deadlines, leading to penalties or delays in receiving payments you’re entitled to.

Additionally, HMRC uses your address to determine your tax code, verify your identity, and administer services like Making Tax Digital. Failure to update your address could result in miscommunication and potential compliance issues. By updating your details promptly, you maintain accurate records and support smooth interaction with tax authorities, minimizing avoidable complications down the line.

How can I update my address with HMRC online?

You can easily update your address with HMRC online using your Government Gateway account. Log in to your HMRC online services, navigate to the ‘Personal Tax Account’ section, and select the option to update your personal details. Follow the prompts to enter your new address, and the change will typically take effect immediately.

For individuals who are self-employed or run a business, you can also update your address through the ‘Self Assessment’ section or your Company Records if you’re a company director. Make sure to have your National Insurance number, Unique Taxpayer Reference (UTR), and details of your new address ready. Confirm that the change has been processed by checking your updated profile afterward.

Can I update my address over the phone or by post?

Yes, you can contact HMRC by phone to notify them of your new address. Call the Self Assessment helpline, the Income Tax helpline, or the relevant department based on your circumstances. Be prepared to verify your identity by providing personal details such as your National Insurance number, date of birth, and previous address.

Alternatively, you can send a written notification by post. Include your full name, National Insurance number, old address, new address, and date of move. Send this letter to the HMRC office you normally deal with, which is usually listed on previous correspondence. While this method is valid, it may take longer to process than online updates.

Do I need to inform HMRC if I’m moving abroad?

Yes, it’s crucial to inform HMRC if you’re moving out of the UK, as your tax obligations may change based on your residency status. Moving abroad could affect your liability for UK Income Tax, Capital Gains Tax, or eligibility for certain benefits. You may need to complete a P85 form to notify HMRC of your departure and determine your tax residency.

Depending on your circumstances, you might be considered a non-resident or partially resident for tax purposes. This affects how much tax you pay on UK and foreign income. HMRC will use your new address and departure date to calculate your tax position, so timely notification helps avoid over or underpayment of taxes.

What happens if I don’t update my address with HMRC?

Failing to update your address with HMRC can lead to missed communications, including tax assessments, reminders, and letters about tax credits or benefits. If you don’t receive a Self Assessment tax return or a payment reminder, you could face penalties, surcharges, or interest on unpaid tax, even if you were unaware of the requirement.

Additionally, outdated information may cause delays in processing tax refunds or benefit claims. It could also complicate identity verification processes or flag your account for unusual activity. Keeping HMRC informed protects your tax compliance status and ensures you receive timely support and information.

Do I need to update my address for each tax service separately?

In most cases, updating your address in your Personal Tax Account will automatically update it across multiple HMRC services, including Income Tax, Self Assessment, and State Pension. HMRC centralizes personal data, so a single update typically synchronizes your information across relevant departments.

However, if you’re registered for specific schemes like VAT, PAYE for employers, or Universal Credit, you may need to confirm the update within those individual accounts. It’s wise to double-check each service you use to ensure consistency. For company directors, updating company details with Companies House does not automatically update HMRC records, so separate action is required.

Can someone else update my address with HMRC on my behalf?

If you have appointed an agent, such as an accountant or tax advisor, they can update your address using their HMRC online services account linked to yours. You must authorize them through the ‘authorise an agent’ feature in your Government Gateway account for them to act on your behalf.

Friends or family members cannot update your address unless they have official authorization. For vulnerable individuals, HMRC may allow a trusted person to assist with prior arrangement and verification. Always ensure that third parties handling your tax affairs are trustworthy and properly authorized to protect your personal and financial information.
