We send you a personalized checklist based on your situation and review every document to confirm it meets IRS acceptance criteria before anything is submitted.
We prepare your complete W-7 application accurately and error-free. IRS rejections are almost always due to form errors, which we eliminate entirely.
We guide you on the safest way to submit certified identification, through your document's issuing agency, a US embassy or consulate, or an IRS Taxpayer Assistance Center, so you can avoid mailing your original passport whenever possible.
Your completed W-7 package is submitted directly to the IRS Austin Service Center via certified mail. We handle the submission so nothing is delayed by address or packaging errors.
We monitor your application status with the IRS and follow up proactively if processing takes longer than expected. You are never left wondering where your ITIN is.
Once your ITIN arrives, we walk you through what to do next: updating your bank account, filing your tax return, linking to your LLC EIN, and any annual renewal requirements.
Applying for an ITIN means proving your identity to the IRS. There are a few accepted paths: mailing your original passport, submitting a certified copy from the passport's issuing agency, or getting your documents certified in person at an IRS Taxpayer Assistance Center or by a Certifying Acceptance Agent. Many applicants do not realize they have options beyond mailing their originals.
We review your documents in detail before anything is submitted, flag anything that commonly causes IRS rejections, and walk you through the certified-copy and in-person options available for your situation so you can choose the path that works best for you. Your completed W-7 package is then prepared error-free and submitted directly to the IRS Austin Service Center.
