You've Been Extended
Your New Mexico return is extended to October 15, 2026. File now to get your refund faster.
New Mexico grants an automatic six-month extension for filing personal income tax returns to taxpayers who have been approved for a federal extension by the IRS. The New Mexico Taxation & Revenue Department aligns with the federal timeline, moving the state filing deadline from April 15, 2026, to October 15, 2026.
Pay 100% to Avoid Interest—Late Payment Penalties Are WaivedNew Mexico has a notably taxpayer-friendly policy: late payment penalties are waived during the extension period. However, if you do not pay 100% of your tax liability by April 15, 2026, interest will still accrue on the unpaid balance from the original due date. To avoid both penalties and interest, pay your full liability by April 15.
New Mexico-Only Extension (No Federal Extension)If you have not filed a federal extension, New Mexico offers an automatic 60-day extension upon a timely initial state application. Extensions beyond 60 days require a written request. Form RPD-41096 may be used to request an additional extension when attached with a copy of any prior state or federal extension.
How to Make Extension Payments- ACH / E-Check (Free): Use the Taxpayer Access Point (TAP) at tap.state.nm.us. Electronic check payments are free.
- Credit Card: Also available through TAP. A convenience fee applies.
- Mail: Use Form RPD-41096 and send to: Taxation and Revenue Department, P.O. Box 8390, Santa Fe, NM 87504-8390.
New Mexico imposes a 2% failure-to-file penalty per month, up to 20%. The failure-to-pay penalty is also 2% per month, capped at 20%—but this is waived during the extension period. Interest on unpaid tax accrues from the original due date regardless.
Best Practices- File IRS Form 4868 to secure your federal extension.
- Pay 100% of your New Mexico tax liability by April 15, 2026, to avoid interest accrual.
- Use TAP at tap.state.nm.us for free e-check payments.
- File your return by October 15, 2026.
New Mexico's extension is taxpayer-friendly—late payment penalties are waived, though interest still accrues if you don't pay in full by April 15. Secure your federal extension, pay via TAP, and file by October 15, 2026.
