Frequently Asked Questions
How long does the ITIN process take?+
After IRS receipt, processing typically takes 7–11 weeks. We track your file the entire time.
Do ITINs expire?+
Yes. An ITIN expires if not used on a U.S. federal tax return for three consecutive years, or based on its middle digits.
Is ITINServices.mx affiliated with the IRS?+
No. We are an independent firm whose principal is an IRS-authorized Certified Acceptance Agent.
How do you protect my personal information?+
Documents are transmitted over an encrypted portal, stored on servers with strict access controls, and never shared outside the engagement.
What causes ITIN rejection?+
Common reasons include missing supporting documents, incorrect W-7 reason codes, or unsigned tax returns. We prevent these before submission.
Can I apply without filing a return?+
Yes, if you qualify for a treaty exception — for example, certain gambling refunds or U.S. financial-institution reporting.
What if my ITIN expired?+
We renew it under the same W-7 process and submit it together with your next U.S. tax filing.
Do I need to mail my passport?+
No. As a Certified Acceptance Agent, we certify your Mexican passport so you keep the original.
