Can I Apply for an ITIN Through an Online Agent From the UK?

Can you apply for an ITIN through an online agent from the UK?
The short answer is yes — many UK residents successfully apply for ITINs remotely through IRS-authorised Acceptance Agents and Certifying Acceptance Agents (CAAs).
However, it is important to understand how the process works, what the IRS allows, and how to ensure the service provider is legitimate.
According to the official IRS Acceptance Agent Program, authorised Acceptance Agents and Certifying Acceptance Agents are approved by the IRS to assist applicants with Form W-7 preparation and ITIN application support.
What Is an ITIN?
An ITIN (Individual Taxpayer Identification Number) is a tax processing number issued by the Internal Revenue Service (IRS) to individuals who are not eligible for a U.S. Social Security Number (SSN) but still need to meet U.S. tax obligations.
UK residents may require an ITIN for:
- Filing U.S. tax returns
- Owning U.S. property
- Operating a U.S. LLC
- Receiving U.S.-source income
- Opening U.S. financial accounts
- Claiming tax treaty benefits
