New Mexico Filing Due Date: Corporation tax returns are due by March 15 — or by the 15th day of the 3rd month following the end of the taxable year (for fiscal year filers).
Extended Deadline with New Mexico Tax Extension: New Mexico offers a 60-day extension for corporations that don’t have a valid Federal tax extension (IRS Form 7004). If you have a 6-month Federal extension, New Mexico will automatically grant you a state tax extension for the same period of time — which moves the New Mexico filing deadline to September 15 (for calendar year filers).
New Mexico Tax Extension Form: To apply for a New Mexico extension, you must submit Form RPD-41096 or a written letter to the NM Taxation and Revenue Department. Your extension request must be filed by the original deadline of your New Mexico return. When initially filed, Form RPD-41096 will provide you with a 60-day extension.
If you have a valid Federal extension (IRS Form 7004), Form RPD-41096 can be used to request an additional New Mexico extension beyond the automatic 6-months.
New Mexico Extension Payment Requirement: An extension of time to file is not an extension of time to pay. If you owe New Mexico tax, it must be paid by the original due date to avoid interest and penalties. Corporations can use Form CIT-EXT to make a New Mexico extension payment. S corporations should use Form S-CORP-EXT to pay tax with their extension request. To make an extension payment electronically, go to New Mexico Online Services: www.tax.newmexico.gov/Online-Services
New Mexico Tax Extension Tip: If you have an approved Federal tax extension from the IRS (Form 7004), you will automatically receive a corresponding New Mexico tax extension.
