New Mexico Tax Extension: Everything You Need to Know

Need more time to file your New Mexico taxes? You’ve got options.

If you're running behind, New Mexico allows both individuals and businesses to request a filing extension. Just remember—an extension gives you extra time to file, not extra time to pay what you owe.

In this guide, we’ll break down everything you need to know: key deadlines, filing requirements, and how to get your extension request submitted quickly and painlessly.

Why File a New Mexico Tax Extension?

Filing a tax extension gives you additional time to prepare and file an accurate return. This is especially helpful if:

• You’re waiting on financial documents or information.
• Your tax situation is complex and requires careful calculation.
• You’ve already filed for a federal extension and want to align your deadlines.

While a tax extension gives you more time to file, any taxes owed must still be paid by April 15th to avoid interest.

How to File a New Mexico Tax Extension

Step-by-Step Guide

1. Determine Your Eligibility:

• Individuals and businesses must establish that they cannot file by the original deadline due to circumstances beyond their control.

2. Submit Form RPD-41096:

• If required, complete and submit Form RPD-41096 to the New Mexico Taxation and Revenue Department by the original due date.
• Include a written explanation of why the extension is needed if required.

3. Make a Payment:

• Payments can be made online at the Taxpayer Access Point - State of New Mexico.

4. Keep Documentation:

• Retain copies of your federal extension approval or New Mexico extension form for your records.

Eligibility and Requirements

Who is Eligible?

• Corporations, S corporations, fiduciaries, pass-through entities, and individuals can file for an extension if they meet the state’s eligibility criteria.

Payment Requirement:

• New Mexico waives failure to file and pay penalties during the extension period. However, unpaid taxes accrue interest daily starting from the original due date. We recommend paying as much as you can to avoid high interest charges.

Federal Extensions:

• If you have a valid federal extension, you do not need to submit Form RPD-41096 unless you need more time beyond what the federal extension provides.

Deadlines and Penalties

Original Filing Deadline:

• April 15th if filing by mail
• April 30th if filing electronically

Extension Deadline (with federal extension):

• October 15th, 2025 — If you filed a valid federal extension (Form 4868), New Mexico will honor it for state filing purposes. No state form is needed.

Extension Deadline (without federal extension):

• You must file Form RPD-41096 by the original due date of the return to request a state-only extension. This extension grants up to 60 additional days to file.

State Extension: A maximum of 60 days is granted by default. Longer extensions require justification and are not guaranteed.

Penalties:

• Interest accrues daily at a rate set quarterly by the New Mexico Taxation and Revenue Department (based on IRS rates).
• Negligence Penalty for late filing or late payment is 2% each month, with a maximum of 20%.
• Failure-to-file and failure-to-pay penalties are waived during the extension period, provided the return is filed and full payment is made by the extended deadline.

What Happens If I Don’t Pay My Taxes by April 15th?

Filing late? Here's what it could cost you.
