For individuals residing in the United Kingdom (UK) who have US tax filing requirements but are not eligible for a Social Security Number (SSN), obtaining an Individual Taxpayer Identification Number (ITIN) is essential. An ITIN allows non-US citizens and residents to comply with US tax laws and reporting requirements. In this guide, we'll walk you through the process of applying for an ITIN from the United Kingdom, providing step-by-step instructions and helpful tips along the way.


Step 1: Determine Your Eligibility

Before applying for an ITIN, it's important to confirm your eligibility. You may be eligible for an ITIN if you:

- Are a non-US citizen or resident alien.

- Have a filing requirement for US tax purposes.

- Need to report income to the Internal Revenue Service (IRS) or claim certain tax treaty benefits.


Step 2: Complete Form W-7

The first step in applying for an ITIN is to complete Form W-7, Application for IRS Individual Taxpayer Identification Number. You can download Form W-7 from the IRS website or obtain a copy from a US embassy or consulate in the UK.


Step 3: Gather Required Documentation

Along with Form W-7, you'll need to submit supporting documentation to verify your identity and foreign status. Commonly accepted documents include:

- Original or certified copies of your passport or national identification card.

- A copy of your birth certificate (if available).

- Documentation to support your eligibility for an ITIN, such as tax returns, letters from financial institutions, or other official documents.


Step 4: Submit Your Application

Once you've completed Form W-7 and gathered all required documentation, you can submit your application to the IRS. There are several options for submitting your application from the UK:

- Mail your application to the IRS address listed on Form W-7.

- Use a Certifying Acceptance Agent (CAA) located in the UK to assist with the application process.

- Visit a US embassy or consulate in the UK to submit your application in person.


Step 5: Await Processing

After submitting your ITIN application, it may take several weeks or months for the IRS to process your application and issue your ITIN. Once assigned (or rejected), the IRS will write to you.


Step 6: Use Your ITIN for Tax Purposes

Once you receive your ITIN, you can use it for tax filing and reporting purposes. Be sure to include your ITIN on any tax returns, forms, or other documents submitted to the IRS.



Applying for an ITIN from the United Kingdom is a straightforward process, but it's important to ensure that you provide accurate information and submit all required documentation. By following the steps outlined in this guide and seeking assistance from tax professionals if needed, you can obtain your ITIN and fulfill your US tax obligations with confidence.
