How To Change Your Address On HMRC: The Complete Compliance Guide
Updating your address with HM Revenue and Customs (HMRC) is a mandatory requirement for maintaining fiscal compliance and ensuring the secure delivery of correspondence regarding your National Insurance, Tax Credits, and Self Assessment accounts. The most efficient method for updating your records is through your Personal Tax Account via the official GOV.UK portal, which typically processes the change immediately for most HMRC services.
Prerequisites for Updating Your HMRC Address
Before initiating the change, verify that you have access to your digital government credentials to avoid delays. HMRC requires verification to prevent identity theft and ensure that sensitive financial documents are not redirected to unauthorized locations.
- Essential Documentation and Data:
- Government Gateway User ID: You must have your unique ID and password. If you have forgotten these, use the account recovery options on the GOV.UK sign-in page.
- National Insurance Number: Keep this readily available as a secondary security verification measure.
- Proof of New Address: While not required during the digital submission, ensure you have a utility bill or bank statement reflecting the new address for your personal records and potential future verification.
- Estimated Duration: The online process typically requires 5 to 10 minutes of active interaction.
- Financial Impact: There is no cost to update your address. Failure to update, however, can result in lost tax refunds or missed deadline notifications, which may lead to late filing penalties.
Systematic Procedure for Updating Your Address
To modify your address, follow the digital workflow established by HMRC. This process synchronizes your data across multiple HMRC departments, including PAYE, Self Assessment, and Tax Credits.
Step 1: Access Your Personal Tax Account
Navigate to the official GOV.UK website and search for "Sign in to your Personal Tax Account." Select the green "Start now" button to be redirected to the Government Gateway sign-in page. Authenticate your identity using your user ID and password. If you have enabled two-step verification, ensure you have your mobile device ready to receive the authorization code.
Step 2: Navigate to Profile Settings
Once logged in, locate the "Your account" or "Profile and settings" section within the main dashboard. This area acts as the centralized hub for all your personal data, including contact details, correspondence preferences, and employment information. Click on the link labeled "Update your address" or "Change your personal details."
Pro-Tip: If you are an employee, check if your employer has updated their payroll records. HMRC often receives address updates directly from employers via the Full Payment Submission (FPS) data sent at the end of each pay period.
Step 3: Enter the New Residential Details
Input your new address using the official address lookup tool provided on the page. By entering your postcode and selecting your house number, the system automatically pulls data from the Royal Mail Postcode Address File (PAF). This ensures the address matches official postal standards, which prevents delivery errors. Ensure that you also specify the date you moved into the new property, as HMRC may need this for retrospective tax calculations.
Step 4: Confirm and Submit Changes
Review the provided summary page to ensure there are no typographical errors in your house name, street, city, or postcode. Click the "Submit" button to finalize the update. You will receive a confirmation message on the screen, and a notification will be sent to your secure message inbox within your Personal Tax Account.
Warning: Do not rely on third-party websites claiming to act as intermediaries for address changes. HMRC does not authorize private agencies to process these updates; using them may expose your personal information to phishing risks.

Addressing Common Update Failures and Errors
Even with a streamlined digital system, users may encounter specific blockers that prevent successful updates. Understanding the root cause is critical to preventing account lockouts.
Failed Authentication:
Root Cause: Incorrect Government Gateway credentials or a lapsed two-factor authentication device.
Actionable Fix: Use the "I have forgotten my user ID or password" link on the sign-in page. Ensure you have your National Insurance number and P60 or recent payslip details to verify your identity during recovery.
Address Not Found in Lookup Tool:
Root Cause: Your new property may be a new build or a complex multi-dwelling unit not yet reflected in the Royal Mail PAF.
Actionable Fix: Choose the option to enter the address manually if the software allows, or contact the HMRC income tax helpline to request a manual entry by an agent.
Multi-Service Data Mismatch:
Root Cause: Your address in the PAYE system does not match the address held by the Department for Work and Pensions (DWP).
Actionable Fix: Verify your details across the GOV.UK "Update your details" hub. If the mismatch persists, call the HMRC department specifically handling your primary income source to reconcile the datasets.
Frequently Asked Questions
Does my employer need to be notified separately?
Yes. Updating your address with HMRC does not automatically update your employer's payroll software. You must provide your new address to your HR or payroll department to ensure your P60, P45, and other statutory documents are mailed to the correct location.
Will changing my address affect my Tax Code?
In most cases, changing your address will not affect your tax code. However, if your move involves relocating between Scotland and the rest of the UK, your tax residency status may change, which could trigger a transition to Scottish Rate Income Tax.
Can I update my address if I am currently under investigation?
If you have an active tax investigation or are in the process of an appeal, you should contact your assigned caseworker directly. While you are still required to update your address, it is vital that the specific team managing your file is aware of the change to maintain the integrity of their correspondence.
Is it necessary to notify HMRC if I move abroad?
Yes. If you are leaving the UK permanently or for an extended period, you must notify HMRC by completing the P85 form. This allows HMRC to determine your tax residency status and ensure you are taxed correctly based on your departure date.
