2026 edition · statute-cited · part of Clear Money Guide’s 51-state retirement tax series. This guide covers state taxes on retirement income and estate transfers; property and sales taxes vary by county and are outside its scope.

Updated July 24, 2026. Quick answer: New Mexico exempts Social Security for the overwhelming majority of retirees — the TY2022 reform makes benefits fully exempt when AGI is at or below $100,000 single / $150,000 joint — but taxes pensions, 401(k) and IRA withdrawals at graduated rates from 1.5% to 5.9% (bracket structure restructured for TY2025 by HB 252), softened by an $8,000 exemption at 65+ that phases out at moderate incomes (NMSA §7-2-5.2). Military retirement gets a $30,000 exemption for armed forces retirement pay, including surviving spouses, with no expiration date in the current statute (NMSA §7-2-5.13). And a genuine curiosity: reach age 100 without being anyone else’s dependent and New Mexico stops taxing you entirely (NMSA §7-2-5.7).

What the 2022–2025 reforms actually left in place

The Social Security exemption is the load-bearing fact — and its AGI test is a cliff worth planning around: at $100,001 single, the exemption is gone entirely — a hard cliff, not a phase-out (NMSA §7-2-5.14; the MFS limit is $75,000) — and federally taxable benefits flow into New Mexico income. The $8,000 65+ exemption applies against all income but phases out quickly; HB 252 (2024) restructured brackets downward for TY2025, lowering effective rates at low and middle incomes. And the military exemption needs a date-stamp most coverage lacks: several national sites describe the $30,000 exemption as applying “2024 and beyond,” and that is now correct: the 2026 sunset was removed and the statute (NMSA §7-2-5.13, incl. surviving spouses) carries no expiration date, so a 2027-and-later move can count on the exemption under current law.

Probate: reasonable fees and a $50,000 affidavit

New Mexico is a UPC state — reasonable compensation (NMSA 1978 §45-3-719), no percentage schedule. Small estates: up to $50,000 of personal property passes by collection affidavit (§45-3-1201) after a 30-day wait. Context: probate cost by state · small-estate limits by state.

Is New Mexico a good state to retire in for taxes?

Below the $100,000/$150,000 AGI lines, quite good: exempt Social Security, modest graduated rates, no death taxes, and cheap probate. Above the lines, the SS exemption vanishes at once — a cliff that makes Roth conversions and withdrawal sequencing unusually valuable here. Military retirees do well; large-drawdown portfolio retirees face the 5.9% top rate with little shelter. Against Arizona’s flat 2.5%, New Mexico wins mainly for lower-income retirees — run both before moving for taxes.

What probate costs in New Mexico

New Mexico sets probate compensation by a “reasonable fee” standard with no percentage schedule, so anyone quoting a firm figure is estimating. And the small-estate shortcut of $50,000 does not clear a solely owned house on its own, which is the detail most guidance omits. Full detail with the governing statute, the court filing fee and the threshold: New Mexico probate cost. To price a specific estate, use the probate cost calculator.
