Who We Help

Confusing U.S. tax rules?

Stay compliant with a trusted pro.

  • Non-U.S. citizens who need an ITIN to file U.S. taxes, claim treaty benefits, or open a U.S. business

  • U.S. expats and citizens living abroad with non-resident alien spouses or children

  • Founders/investors and foreign entities that need an EIN

  • U.S. expats and nonresident aliens who need U.S. tax filing support (1040-NR, treaty positions, real estate sales, inheritance, withholding questions)

Why Work with a Certified Acceptance Agent (CAA)

  • Identity & status verified without mailing your passport to the IRS

  • Application accuracy that avoids common document rejection errors

  • Direct coordination with the IRS ITIN unit to monitor progress and resolve issues

Our Services

  • ITIN (Form W-7) preparation & CAA certification

  • EIN acquisition for non-U.S. entities and startups

  • U.S. tax returns & forms for nonresidents/expats (1040, 1040-NR, treaty disclosures)

  • Advisor/firm bundles (law, investment, property managers) when multiple client ITINs are needed

Documents Required

  • Valid passport (or accepted alternative ID)

  • Supporting reason for ITIN (filing a tax return, treaty article, etc.)

  • Additional documents (W-2/1099/1042-S/K-1 as applicable)

3-Step Process

  1. Intake & Reason Check: we confirm your ITIN reason and documents

  3. Submission & Tracking: I file your W-7/return and track status with the IRS

Once we verify your ITIN reason, the process is easy: 

Timing & Expectations

​ITIN processing is controlled by the IRS. We prepare, certify, and submit quickly; the IRS timeline varies by season and workload. Processing usually takes several months.
