Preparing ITIN docs

Venturing into the U.S. tax compliance sphere, especially as a foreign national or non-resident alien, necessitates having an Individual Taxpayer Identification Number (ITIN). Getting this nine-digit number from the IRS involves a step-by-step process. Having the right documents ready is key.

In this post, we share a detailed checklist. It will help make your ITIN application process smoother. We also explain how ITIN Support can guide you through it.

The Document Trail to ITIN

IRS Form W-7:

The IRS Form W-7 is central to your ITIN application. It's also known as the 'Application for IRS Individual Taxpayer Identification Number'. It's essential to fill out all the fields accurately to ensure the information reflects your current status.

Federal Tax Return:

Unless you qualify for an exception, attach your federal tax return with the W-7 form. This document serves as a basis for your tax compliance.

Proof of Identity and Foreign Status:

The IRS requires original documents or certified copies from the issuing agency to verify your identity and foreign status. Commonly accepted documents include:

  • Passport (which can stand alone)
  • National ID card (must be in English)
  • U.S. driver’s license
  • Foreign driver’s license
  • U.S. state ID card
  • Foreign voter’s registration card
  • Visa issued by U.S. Department of State

Additional Documents:

Your situation might require extra documents. These could include birth certificates, school records, or other official papers that support your claims.

Certified English Translation:

For documents in languages other than English, a certified English translation is necessary.

The Road Less Traveled: Exception Applications

Certain individuals don't need to submit a tax return with their ITIN application. These include:

  • Spouses or dependents of U.S. citizens or resident aliens.
  • Spouses or dependents of non-resident alien visa holders.

Enlist the Help of Certified Acceptance Agents (CAAs)

The ITIN application process can be complex, but Certified Acceptance Agents (CAAs) can provide invaluable assistance. They review your documents, provide necessary certifications, and forward your application to the IRS, ensuring accuracy and completeness. ITIN Support offers a platform to connect with CAAs, simplifying the process for a smoother experience.
