Our Services

What our ITIN service covers

From eligibility review to ITIN delivery, we break the process into four clear stages. Start with the one that matches where you are today.

01
Eligibility

Get the qualifying reason right — that's where most rejections start

On Form W-7, the "Reason for applying" field is the single most common cause of rejection. We map your real situation — LLC ownership, marketplace seller, U.S. tax return filing, treaty benefits, dependent or spouse — to the correct reason code, then list exactly which supporting documents the IRS expects for that reason.

  • Review of passport, visa status, income sources, and qualifying reason
  • Walk through related materials: LLC operating agreement, platform statements, tax filings
  • Determine upfront whether your case needs a 1040-NR return or can be filed standalone

Six pitfalls most ITIN applicants hit

These are the points where applications get stuck. Wrong reason code, missing documents, lost passports — any one of them can cause a rejection and add months to your timeline.

Wrong qualifying reason
Picking the wrong "Reason for applying" code on Form W-7 — or choosing one that doesn't match your supporting documents — is the single biggest cause of rejections.
Mailing your passport
Sending your original passport to the IRS is risky — loss, delay, and travel disruption all happen. CAA online verification removes that risk entirely.
Unverified CAA credentials
Many providers claim to handle ITINs, but only a fraction hold a real IRS CAA authorisation. Working with a provider not listed on IRS.gov is a compliance risk.
W-7 form errors
Date of birth, address, name transliteration, signature placement — any small mistake on the W-7 can trigger a request for additional information and delay you by months.
No visibility after mailing
Once the W-7 is in the mail, most applicants have no way to track it. We've seen people wait three months only to discover their application was rejected weeks earlier.
No support after rejection
Plenty of agents take the money and disappear. When the IRS rejects an application, applicants are left to handle the resubmission, identity re-verification, and tax adjustments on their own.
