What Should You Look For in an ITIN Service?

7 factors distinguish a quality ITIN service from a risky one. Use this checklist when evaluating any provider, including itin.so.

1. IRS-Authorized CAA Status

A Certifying Acceptance Agent (CAA) is authorized by the IRS under Revenue Procedure 2017-14 to verify identity documents. This means you keep your original passport. Non-CAA services require you to mail your passport to the IRS or use a notarized copy. Verify CAA status at IRS.gov. itin.so is an IRS-authorized CAA. Read about the CAA vs regular agent difference.

2. Transparent Pricing

The full cost should be stated upfront with no hidden fees. Some services advertise low base prices then add document review fees, submission fees, or rush charges. itin.so pricing: $297, EIN $97. No additional charges. Compare on our ITIN cost guide.

3. Document Security

Your passport and identity documents should never leave your hands. CAAs verify documents and submit a Certificate of Accuracy (Form 13551) to the IRS instead of your originals. This protects against lost documents in the mail. The IRS receives approximately 5 million pieces of mail daily; documents do get lost.

4. Responsive Support

Questions should get answered within 1 business day. If the IRS sends a notice (CP 567, CP 566) about your application, the service should help you respond. itin.so offers WhatsApp support (+880 1750 278508) for all clients. Learn more about our team.

5. Free Resubmission Policy

If the IRS requests corrections or additional documents, the service should resubmit at no extra charge. Some providers charge $50-$150 for resubmissions. Both itin.so plans include free resubmission for IRS-requested corrections.

6. Multi-Language Support

ITIN applicants come from 150+ countries and speak dozens of languages. At minimum, a service should operate in English and Spanish, since Spanish-speaking applicants represent a large portion of ITIN filers. itin.so operates in both English and Spanish.

7. Clear Processing Timeline

The service should clearly state preparation time (their part) separately from IRS processing time (6-11 weeks, which no service can speed up). Be cautious of services claiming to get ITINs in 2-3 weeks, as only the IRS controls processing speed. Check current IRS processing times.
