New Mexico recognizes and accepts an IRS automatic extension of time to file. If you obtained the federal six-month automatic extension by filing federal Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return for tax year 2020, you have until October 15, 2021 to file your New Mexico return.
To extend your deadline beyond the six months, you are required to obtain an additional extension through the IRS or the state.
If you only need a New Mexico extension, submit Form RPD-41096, Application for Extension of Time to File .
Note that this is an extension of time to file, not an extension to pay any tax due.
