New Mexico Tax on Inherited IRA Withdrawals (2026)

Updated October 16, 2026. Quick answer: New Mexico’s documents read give an IRA distribution no exclusion and do not mention inherited IRAs: the PIT-1 return starts from “federal adjusted gross income as reported on your federal Form 1040”, and the retirement exemptions printed include one for armed forces retirement pay.

What the New Mexico documents say

The PIT-1 instructions list an IRA distribution among the payments for which a filer should “collect all your federal Form(s) 1099-R, RRB-1099 and SSA-1099”. The return then starts from federal adjusted gross income on the federal Form 1040.

On beneficiaries the instructions speak only of estates and trusts: “each beneficiary of the estate or trust must include” the beneficiary’s share of the estate or trust income on the New Mexico PIT-1. That is about income an estate or trust passes through, and the instructions do not say how an inherited IRA is treated.

The PIT-ADJ instructions allow “an amount equal to $30,000 of armed forces retirement pay” for an armed forces retiree or the surviving spouse of one. A separate exemption for persons 65 or older, or blind, says “You may be eligible for an exemption of up to $8,000” based on filing status and federal adjusted gross income.

The federal 10-year rule and your New Mexico tax year

IRS Publication 590-B says a beneficiary may be required to take the entire account balance by the “end of the 10th year following the year of the owner’s death”, with exceptions for certain beneficiaries. Because the balance generally has to come out within that window, the timing of each withdrawal decides which tax year it lands in. See the 10-year rule and annual RMDs, lump sum versus spreading withdrawals and inherited IRA rules.

Withholding and other state taxes

Whether a state withholds from a withdrawal is a separate rule: see state withholding on retirement withdrawals. For New Mexico’s own death taxes, see inheritance tax by state.

What the documents do not say

  • The documents read do not mention inherited accounts or beneficiaries of retirement accounts.
  • The documents read do not print New Mexico’s rate schedule, so none is shown here.
  • They do not say whether the $8,000 exemption for persons 65 or older can be claimed by a beneficiary of an inherited IRA.
  • They say nothing about a deduction or credit for estate tax or income in respect of a decedent.

Common mistakes

  • Assuming New Mexico’s rule for your own retirement income also covers an account you inherited: read whether its documents address beneficiaries, and confirm the point with a New Mexico preparer.
