Estate Tax 

Residents and nonresidents of New Mexico are subject to the Estate Tax Act, Section 7-7-1 et seq. NMSA 1978. If there is a federal requirement to file a federal estate tax return, the estate’s personal representative must file a return with the Taxation and Revenue Department (TRD). The state filing must be completed on or before the deadline for the federal estate tax return, a copy of which must accompany the state filing.  

The due date of the tax is the same as the federal deadline to file and pay, including any extension of time for filing the federal estate tax return.

Estate tax dollars, after refunds, go into the General Fund. Works of art may be accepted in lieu of payment of estate tax under certain circumstances.

The estate tax equals the federal credit on the transfer of the net estate for residents. For nonresidents the tax equals the federal credit imposed on the net estate located in New Mexico.

Taxpayers should make the check or money order payable to Taxation and Revenue Department. Mail the form with payment to:  

New Mexico Taxation and Revenue Department
P.O. Box 25123
Santa Fe, NM 87504-5123

Frequently Asked Questions

Q. Does New Mexico have an estate tax?

Yes. The estate tax applies to the New Mexico portion of the net estate as a proportionate share of the federal credit for state estate taxes. The net estate located in New Mexico of a nonresident is also taxable as a fraction of the federal credit.

Q. Does New Mexico have an inheritance tax on heirs?

No, but an inheritance may be reflected in a taxpayer's modified gross income as defined by New Mexico. If so, New Mexico personal income tax laws would then apply.
