Does New Mexico have an estate tax or an inheritance tax?

No New Mexico inheritance tax

The New Mexico Taxation and Revenue Department states that New Mexico does not impose an inheritance tax. Someone who inherits money, a house or other property from a New Mexico estate does not pay a state tax simply for receiving it.

New Mexico's estate tax has been phased out

According to the Taxation and Revenue Department, New Mexico's estate tax was phased out because of federal tax law changes as of January 1, 2005. For deaths since then, New Mexico does not collect an estate tax.

There is one paperwork wrinkle. The department says that if a federal estate tax return (Form 706) must be filed for any reason, a New Mexico estate tax return should also be filed. In practice that affects only the small number of estates large enough to need a federal return.

The federal estate tax in 2026

The federal estate tax applies only to large estates. The IRS reports that the basic exclusion amount for people dying in 2026 is $15,000,000, up from $13,990,000 in 2025, after legislation amended the Internal Revenue Code to set the 2026 figure.

A federal estate tax return is required when the gross estate, plus adjusted taxable gifts and specific gift tax exemption, exceeds the threshold for the year of death. The gross estate counts everything the person owned or had certain interests in at death, at fair market value, including cash and securities, real estate, insurance, trusts, annuities and business interests. That includes property that passes outside probate.

Most Albuquerque estates are far below this level and owe no federal estate tax.

Married couples and portability

Property that passes to a surviving spouse can generally be deducted when the taxable estate is calculated. The IRS also allows the estate of a person survived by a spouse to elect to pass any unused exclusion to the surviving spouse. That election is made on a timely filed estate tax return, so some families file Form 706 even when no tax is due. A tax professional can tell you whether it is worth doing.

Gifts

For 2026, the IRS lists the federal annual gift tax exclusion as $19,000 per recipient. Larger gifts during life interact with the estate tax exclusion, so anyone giving large amounts should get tax advice first.

Taxes that can still apply to an estate

• The decedent's final income tax returns, federal and New Mexico, for the year of death.
• Income the estate earns after death, such as interest, rent or a gain on a sale, which can require fiduciary income tax returns. The Taxation and Revenue Department covers New Mexico's fiduciary income tax on the same page as its estate tax guidance.
• Property tax on real estate keeps running during probate and has to be paid from the estate.
• Other states. If the person lived in, or owned real estate in, another state, that state's estate or inheritance tax rules may apply.

Paying taxes is one of the personal representative's jobs before distributing property. See personal representative duties and probate costs.

What this means for planning

Because state death taxes are not a factor and the federal threshold is high, most New Mexico families plan for other reasons: avoiding probate, protecting a spouse's share of community property, and naming who will handle money and medical decisions. See estate planning in Albuquerque. Tax law changes often, so check the current IRS figures in the year of death.
