Who is required to file a state income tax return in New Mexico?

This requirement applies to both residents and non-residents, as well as members of the military whose residence is still based in New Mexico and members of an Indian tribe or reservation who live or work on land outside of the reservation.
You must also file a New Mexico state income tax return if tax was withheld from your paycheck and you want to obtain a refund.
What is the tax rate for New Mexico state income tax?
New Mexico uses a graduated tax rate with seven tiers ranging from 1.7% to 4.9%.
How do I obtain an extension of time to complete and file my New Mexico state income tax?
New Mexico state income tax is normally due on April 15 of each year. When April 15 falls on a holiday or weekend, tax returns are due on the next business day. However, if you file and pay your state income tax return online, the due date is extended to April 30.
By completing form RPD-41096, you can request an extension of time to file your state income tax return. This form must be submitted by April 15 in order for it to be accepted. Failure to obtain an approved extension may make you subject to penalties and interest on any unpaid tax liability.
New Mexico generally limits extensions of time to file to 60 days, so long as you demonstrate a good cause for the extension. An inability to pay the tax you owe is not considered sufficient reason for an extension.
Even if New Mexico accepts your extensions, they will charge you interest on any unpaid tax liability. In addition, remember that an approved extension only provides you most time to file your state income tax return. There are no extensions on the time to pay any tax liability due, which means you must still pay an estimate of any tax due by April 15.
