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: Standard $197, Express $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 email support for Standard and WhatsApp support (+880 1750 278508) for Express. 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.

Frequently Asked Questions About itin.so Reviews

Is itin.so a legitimate ITIN service?

Yes. itin.so is an IRS-authorized Certifying Acceptance Agent (CAA) service. The IRS vets and approves CAAs under Revenue Procedure 2017-14 to verify identity documents and submit ITIN applications. CAAs allow applicants to keep their original passports instead of mailing them to the IRS. You can verify CAA status through the IRS Acceptance Agent Program page at IRS.gov.

How much does itin.so charge for ITIN applications?

How long does the itin.so ITIN process take from start to finish?

Standard service preparation takes 7-10 business days. Express service preparation takes 2-3 business days. After we submit your application, the IRS takes 6-11 weeks to process and issue your ITIN. Total timeline from starting your application to receiving your ITIN is 8-14 weeks for Standard and 7-13 weeks for Express. Peak tax season (January-April) pushes processing toward the longer end.

What countries does itin.so serve?

itin.so serves applicants from 150+ countries worldwide. We operate in English and Spanish. Top countries include Canada, United Kingdom, India, Brazil, Germany, Australia, Nigeria, Mexico, Colombia, and the Philippines. Non-resident applicants from any country can use our service as long as they have a valid passport or qualifying identity document.

What documents do I need to apply through itin.so?

You need a valid passport (most common), completed Form W-7 (we prepare this for you), and a qualifying tax reason such as a tax return, treaty benefit claim, or third-party withholding. As a CAA, we verify your passport in person or via secure video, then submit a Certificate of Accuracy to the IRS. You keep your original passport throughout the process.

Does itin.so offer a money-back guarantee?

Yes. The Express service ($297) includes a money-back guarantee. If the IRS rejects your application due to an error on our part, we refund your service fee in full. We also resubmit your application at no additional cost. Standard service includes free resubmission if the IRS requests corrections but does not include a money-back guarantee.

How can I contact itin.so support?

Standard service customers receive email support with responses within 1 business day. Express service customers get WhatsApp support at +880 1750 278508 for faster responses. You can also reach us through the contact form on our website. We provide status updates at every stage: application submitted, IRS receipt confirmed, and ITIN issued.

What is the difference between a CAA and a regular tax preparer for ITIN applications?

A Certifying Acceptance Agent (CAA) can verify your identity documents and submit a Certificate of Accuracy to the IRS, which means you keep your original passport. A regular tax preparer or Acceptance Agent (AA) cannot certify documents, so you must mail your original passport to the IRS or use notarized copies. CAAs undergo IRS background checks and must complete annual training.

Can I leave a review for itin.so?

Yes. After your ITIN is issued, we send you an email with a link to share your experience. You can also contact us directly through our website to provide feedback. We welcome honest reviews from all customers, both positive and constructive. Every review helps us improve our service and helps future applicants make informed decisions.

What happens if the IRS rejects my itin.so application?

If the IRS rejects your application, they send a letter (CP 567) explaining the reason. Common reasons include incomplete Form W-7, missing or unacceptable documents, and name discrepancies. We help you understand the rejection, correct the issues, and resubmit at no additional charge. Both Standard and Express plans include free resubmission for IRS-requested corrections.
