Taxes in Las Cruces
New Mexico's real, current 2026 graduated income tax (1.5% to a top 5.9%) and its hard-cliff Social Security exemption run genuinely favorable for many movers, alongside a currently time-limited military retirement pay exemption and Las Cruces's own recently-increased gross receipts tax -- a real, honestly mixed overall tax picture this record discloses precisely.

Learn moreNew Mexico's Real, Current Graduated Income Tax: 1.5% to a Top 5.9%
New Mexico's real, current individual income tax applies six graduated brackets for 2026, from 1.5% up to a top 5.9% rate applying above $210,000 taxable income (single filers; $315,000 for married filing jointly). This record verified this exact current bracket structure fresh this pass rather than assuming an earlier year's figures still apply.
A Real, Hard-Cliff Social Security Exemption -- Not a Phase-Out
New Mexico exempts Social Security benefits from state income tax only for taxpayers with AGI under real, current thresholds ($100,000 single / $150,000 married filing jointly, head of household, or surviving spouse / $75,000 married filing separately). This is a real, disclosed HARD CLIFF: income at or above the threshold makes the federally-taxable portion of benefits (up to 85%) taxable at ordinary graduated rates. Other retirement income (pensions, 401(k)/IRA withdrawals) is taxed at New Mexico's ordinary 1.5%-5.9% rates with no separate broad exemption.
A Real, Currently Time-Limited Military Retirement Pay Exemption -- Genuinely Relevant Given White Sands Missile Range
New Mexico's military retirement pay exemption (up to $30,000/year) is enacted only for tax years 2024 through 2026 under current law -- 2026 is its final year unless extended. Separate, real, still-pending 2026 legislation (SB497) would remove the dollar cap entirely, but this record did not independently confirm this pass whether that bill was enacted. Active-duty military pay for New Mexico resident service members remains fully exempt regardless of this cap.
Gross Receipts Tax: Las Cruces's Own Rate Rose to 8.39% in July 2025
Las Cruces's combined gross receipts tax (New Mexico's functional sales-tax equivalent) rose from 8.065% to a real, current 8.39% effective July 1, 2025, following a voter-approved November 2024 ballot measure projected to generate approximately $11 million/year for capital improvements. Groceries and medicine remain exempt from the tax base.
Property Tax: Genuinely Comparable to the National Median in Las Cruces Specifically
As detailed in full on the property-taxes topic page, New Mexico's real 1/3 assessment ratio keeps property tax bills comparatively low relative to home value statewide, but Las Cruces's own cited median effective rate (~0.99%) runs closer to the national median (~1.02%) than New Mexico's broader low-tax reputation might suggest -- a real, disclosed local nuance.
Key takeaways
- New Mexico's real, current graduated income tax runs 1.5% to a top 5.9% (above $210,000 single / $315,000 MFJ taxable income) for 2026.
