Why UK Residents Need a US ITIN

The United Kingdom has close economic ties with the United States. British entrepreneurs, investors, and professionals regularly operate US entities, receive US income, or invest in US markets — all of which trigger IRS reporting obligations that require an ITIN.

Why British residents apply for a US ITIN:

  • US LLC or C-Corp ownership — annual IRS filing requires ITIN
  • Amazon UK sellers expanding to US — tax documentation required
  • US investment income — dividends, interest (US-UK treaty reduces withholding)
  • Consulting or freelancing for US companies — W-8BEN requires ITIN
  • YouTube, Twitch, Substack — US-sourced creator income
  • US real estate — FIRPTA withholding requires ITIN to reduce rate

US-UK Tax Treaty: The United Kingdom and the United States have a comprehensive double taxation agreement. British residents with an ITIN and W-8BEN can reduce or eliminate withholding taxes on dividends, royalties, and interest.

⚠️ Critical: Use an IRS Certified Acceptance Agent (CAA)

Many ITIN services are not registered IRS Certified Acceptance Agents. When a non-CAA submits your W-7, the IRS may reject it — issuing a CP567 notice that explicitly states the submitter lacked CAA authorization. This can cost you months of delays and lost fees.

ITIN Plus is a registered IRS Certified Acceptance Agent. We submit your application directly to the IRS with certified document authentication. Your application is processed correctly from day one.

Frequently Asked Questions — ITIN for United Kingdom Residents

Can a UK resident get a US ITIN without travelling to the US?

Yes. As an IRS Certified Acceptance Agent (CAA), ITIN Plus authenticates your documents remotely. No US embassy or consulate visit required.

How long does ITIN take for UK residents?

8–14 weeks from CAA submission to the IRS. This is faster and safer than self-filing, which requires mailing your original passport.

Does the US-UK tax treaty benefit ITIN holders?

Yes. The US-UK Double Taxation Agreement allows British residents to reduce withholding on US dividends to 15% and royalties to 0% using a W-8BEN with ITIN.

What documents does a British resident need?

A valid UK passport is the primary document. For LLC-related applications, your EIN confirmation letter is also required.

What is the cost?

$99 flat fee. No hidden charges. No annual renewals.

Why not apply for an ITIN directly through the IRS?

Direct IRS applications require mailing your original passport, which can take 11+ weeks and risks document loss. CAA submission is faster, safer, and certified.
