ITIN Renewal for Mexico-Based Tax Refund Claimants
Non-residents in Mexico owed a U.S. tax refund face a specific hurdle when their Individual Taxpayer Identification Number (ITIN) has expired. Unlike individuals applying for a new ITIN, you are specifically looking to renew an existing number. This often arises for individuals who previously filed U.S. tax returns, perhaps as rental property owners, freelancers, or in cross-border family situations, and are now seeking to claim a refund of over-withheld U.S. tax. The U.S.-Mexico tax treaty may offer benefits, but an expired ITIN prevents filing the necessary Form 1040-NR to claim these refunds. The IRS uses a rolling expiration schedule for ITINs, meaning even if you haven't filed recently, your ITIN might be invalid. Proactively checking your ITIN status before tax season is more efficient than waiting for IRS notices like the CP-48.
When ITIN Renewal is Required
Your ITIN requires renewal if it has expired. The IRS inactivates ITINs that have not been used on a federal tax return for three consecutive years. Additionally, the IRS has implemented a rolling expiration schedule based on the middle digits of the ITIN. For example, ITINs with the middle digits 70, 71, or 72 issued before 2013 expired in 2023. ITINs with middle digits 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, and 90 issued before 2013 expired in 2024. If you received a CP-48 notice from the IRS, it indicates your ITIN is no longer valid for tax filing. However, relying solely on this notice is risky; many individuals do not receive one. It is best to verify your ITIN's validity proactively, especially if you intend to file a tax return to claim a refund.
Required Documents for ITIN Renewal
To renew your ITIN, you must submit an application using Form W-7, with the 'Renew an Existing ITIN' box checked. You will need to provide original or certified copies of specific identification documents. The most critical document is typically your valid passport. If you do not have a passport, other identification documents may be accepted, but a passport is the preferred primary identification. You may also need to provide your previously issued ITIN notice, if available, to help the IRS locate your record. Crucially, you must also include your current federal tax return with your Form W-7 application. This demonstrates your need for an ITIN for tax purposes. Ensure all submitted documents are clear, legible, and accurate to avoid processing delays.
The ITIN Renewal Application Process
The ITIN renewal process begins with completing Form W-7, ensuring you check the box for renewal. You must then gather your supporting identification documents and your current federal tax return. There are two primary methods to submit your application: directly to the IRS or through a Certified Acceptance Agent (CAA). Submitting directly to the IRS requires mailing your original identification documents, which can be a concern for many. The IRS typically processes ITIN applications within 5–10 business days when submitted through a CAA. If you apply directly to the IRS, processing times can be significantly longer. Using a service like itin.net, which acts as a / Certified Acceptance Agent, can expedite the process and secure your original documents.
Common Mistakes for Mexico-Based Tax Refund Claimants
Tax refund claimants in Mexico often make specific errors during the ITIN renewal process. One common pitfall is not checking the ITIN status proactively and waiting for a CP-48 notice, which may never arrive. Another frequent issue involves discrepancies in personal information. Ensure the name on your Form W-7 exactly matches your passport and any other identification documents. Mismatched names are a primary reason for application rejection. Furthermore, ensure you are filing the correct tax form; for non-residents claiming refunds, this is typically Form 1040-NR. Incorrectly filed tax returns can delay or jeopardize your refund claim and ITIN renewal.
Benefits of Using a Certified Acceptance Agent (CAA)
A Certified Acceptance Agent (CAA) acts as an IRS-authorized intermediary who can help you through the ITIN application or renewal process. When you use a CAA like itin.net, they can verify your original identification documents, such as your passport, on your behalf. This means you do not have to mail your original documents directly to the IRS, reducing the risk of loss or delay. The CAA reviews your application package, including Form W-7 and supporting documents, for completeness and accuracy before forwarding it to the IRS. This pre-screening significantly increases the chances of your application being accepted without further delays. The typical timeline for ITIN renewal through a CAA is considerably faster, often within 5–10 business days.
Next Steps After ITIN Renewal
Once your ITIN renewal is approved, you will receive an official ITIN assignment letter from the IRS. You can then use this renewed ITIN to file your pending Form 1040-NR to claim your tax refund. Ensure you correctly enter the renewed ITIN on all relevant tax forms. If you are considering other U.S. tax or business matters, such as forming a /llc or opening a /bank-account, having a valid ITIN is often a prerequisite.

Practical tips
- Use the same legal name across Form W-7, your passport, and any prior IRS correspondence; mismatched name fields are the most common rejection reason.
- Double-check that your ITIN middle digits are not part of the current IRS expiration schedule; proactive verification avoids last-minute filing issues.
- Ensure your submitted tax return is complete and accurate before attaching it to your Form W-7 renewal application.
- If using original documents, consider using a traceable courier service when sending them to the IRS or a CAA.
- Keep copies of all submitted documents, including your Form W-7 and passport, for your records.
Frequently asked questions
How do I know if my ITIN has expired?
Your ITIN may have expired if it hasn't been used on a federal tax return for three consecutive years or if its middle digits fall within the IRS's current expiration schedule. You might receive a CP-48 notice, but it's best to check your status proactively.
Can I renew my ITIN online?
No, the ITIN renewal process cannot be completed entirely online. You must submit Form W-7 along with original or certified copies of identification documents and your current tax return, either by mail to the IRS or through a Certified Acceptance Agent (CAA).
What is the difference between a new ITIN application and renewal?
A new ITIN application is for individuals who have never been issued an ITIN. Renewal is for those who previously had an ITIN that has since expired or become invalid due to non-use or the IRS's expiration schedule. The application form, Form W-7, is used for both, but you must check the appropriate box.
How long does ITIN renewal typically take for someone in Mexico?
When applying through a Certified Acceptance Agent (CAA) like itin.net, the typical processing time for ITIN renewal is 5–10 business days. Applying directly to the IRS can take significantly longer.
Do I need my old ITIN card to renew?
You do not need your old ITIN card, but having your old ITIN notice or knowing your ITIN number is essential for the renewal application.
Can I use my Mexican passport for ITIN renewal?
Yes, a valid Mexican passport is typically the primary identification document accepted for ITIN renewal applications.
