Who this ITIN service in Mexico is for
The IRS list for Mexico showed 10 acceptance agents on 6 Nov 2026; listing is opt-in, so the real number may be higher.
You have to file a U.S. tax return
You earned U.S. income while living in Mexico and can’t get a Social Security number, so the return needs an ITIN.
You own part of a U.S. LLC or partnership
Members of multi-member LLCs and partners often need an ITIN for the return or the K-1 they receive.
You are the spouse or dependent on a U.S. return
Each person listed on the return without an SSN needs their own ITIN and their own documents.
You sold or rent out U.S. property
Property sellers and landlords often need an ITIN to report the sale or rent and to get back withholding.
Your ITIN expired or will expire
An ITIN not used on a federal return for three tax years in a row expires. Renewal uses the same Form W-7.
Your application was rejected
Got a CP567 or CP566 notice? We read the reason, fix the documents and file again correctly.
Getting an ITIN from outside the U.S. is full of small traps
The IRS rejects a large share of ITIN applications, and most rejections and long delays come from a handful of avoidable mistakes: the wrong documents, a missing tax return or exception proof, or originals lost in the mail.
Common pitfalls
What usually goes wrong when filing alone
- Mailing your original passport to the IRS in Austin and waiting weeks to get it back.
- Using a notarized copy, which the IRS does not accept.
- Ticking the wrong W-7 reason, or missing the tax return or exception documents the IRS requires.
- Names and dates that don’t match across the passport, the W-7 and the tax return.
Our approach
How we prevent each of those problems
- Our CAA examines your original passport on a recorded video call and certifies a copy.
- Only the CAA-certified copy goes to the IRS with your application.
- We confirm your W-7 reason and the return or exception documents before filing.
- Every W-7 line is checked against your passport and supporting documents.
What we actually do for you
Check your case and documents
We confirm you need an ITIN at all, pick the right W-7 reason and confirm whether you file with a tax return or under an exception. Your passport from Mexico is usually the only identity document needed.
Verify your passport by video
You show your original passport on a recorded video call with our Certifying Acceptance Agent. We then certify the copy and prepare your Form W-7 for your approval.
File and follow up with the IRS
We send the W-7, the certified copy and your return or exception documents to the IRS, then track the application until your CP565 assignment notice arrives.

Three ways a Form W-7 reaches the IRS
Every ITIN application needs the W-7, proof of identity and foreign status, and usually a tax return. These are the routes the IRS lists for getting your documents to it. You can use any of them yourself — the ITIN is free.
| Route | How it works | Who can use it | Your original documents |
|---|---|---|---|
| Certifying Acceptance Agent (CAA) | An IRS-authorized agent reviews your original passport (in person or on a video interview) and certifies a copy | Anywhere in the world | Original passport is not mailed to the IRS |
| Mail to the IRS | Internal Revenue Service, ITIN Operation, P.O. Box 149342, Austin, TX 78714-9342 | Anywhere in the world | You mail originals or copies certified by the issuing agency; originals are returned by mail |
| IRS Taxpayer Assistance Center | In-person appointment at a designated IRS office (844-545-5640) | Inside the U.S. only | Documents reviewed and returned at the appointment |
- Processing time. The IRS says to allow 7 weeks for an ITIN decision, or 9–11 weeks if you apply during peak season (January 15 – April 30) or from overseas. Nobody — no agent and no paid service — can make the IRS process an ITIN faster.
- Certified copies only. Copies must be certified by the agency that issued the document. Notarized copies are not accepted.
- A return, or an exception. Form W-7 must be attached to a valid federal income tax return unless you qualify for one of the exceptions listed in the W-7 instructions.
Why the route matters: Applications filed through a Certifying Acceptance Agent were rejected 12.3% of the time, against 27.3% when originals were mailed to the IRS and 18.4% through IRS offices (National Taxpayer Advocate, CY2023 to September 2024).
What to expect when you apply from Mexico
Two clocks apply to every ITIN. Ours: we prepare and certify your application within 1–3 business days of receiving your documents and completing the video verification. The IRS’s: it says to allow 7 weeks, or 9–11 weeks from January 15 to April 30 or when you apply from abroad — and nobody can speed that up. We track your application through the IRS wait, follow up once the IRS window has passed, and tell you as soon as your ITIN is assigned.
Day 1 — fit check
You tell us why you need an ITIN. We confirm the W-7 reason and the documents it needs.
Within 1–3 business days — prepared and certified
After you send your documents and complete the video verification, we prepare the W-7 and certify your passport copy.
On your approval — filed with the IRS
We send the application package to the IRS ITIN Operation and keep you updated.
IRS processing — allow 9–11 weeks from abroad
The IRS says to allow 7 weeks for an ITIN decision, or 9–11 weeks if you apply during peak season (January 15 – April 30) or from overseas. Nobody can shorten this. The IRS mails the CP565 notice with your ITIN.

Common questions from non-U.S. applicants
If your question isn't here, contact us — we'll answer honestly, even if the answer is 'this isn't a fit for our service.'
Can I get an ITIN while living in Mexico?
Yes. You don’t need to travel to the U.S. An ITIN is for individuals who have a U.S. federal tax filing or reporting requirement and are not eligible for a Social Security number. You can apply from Mexico by mailing your documents to the IRS yourself, or through a Certifying Acceptance Agent like us, who verifies your passport and certifies a copy.
Do I have to send my original passport to the IRS?
Not if you apply through a Certifying Acceptance Agent. Our CAA examines your original passport on a recorded video call and certifies a copy, and the copy goes to the IRS. Copies must be certified by the agency that issued the document. Notarized copies are not accepted.
Does the U.S. tax treaty with Mexico matter for my ITIN?
It can. The U.S. has an income tax treaty with Mexico. If you need an ITIN to claim a treaty benefit, Form W-7 reason (a) applies, and you may be able to apply without a tax return under Exception 2 — with documents that show the treaty claim, such as a letter from the payer. Whether a benefit applies to your income is a tax question; we check that the W-7 reason and documents match what you or your tax adviser decide.
How long does an ITIN take from Mexico?
Two clocks apply. Ours: 1–3 business days to prepare and certify after we have your documents and the video verification. The IRS’s: 7 weeks (9–11 weeks from January 15 to April 30 or from abroad). Applications from abroad fall in the longer window. Nobody can make the IRS go faster.
How much does it cost?
The IRS charges nothing for an ITIN. Our fee covers preparation, CAA certification, filing and follow-up. See the pricing page for our packages.
How do I check an acceptance agent in Mexico?
The IRS publishes acceptance-agent lists by country. The IRS list for Mexico showed 10 acceptance agents on 6 Nov 2026; listing is opt-in, so the real number may be higher. Agents based in other countries can also serve you by video. You can check our own status on our Verify us page.
