Introduction
New Mexico has several tax features that distinguish it from other western states. The state’s income tax system is progressive with five brackets, topping out at 5.9% for high earners — a rate added in 2021 that applies only to income above $210,000 for single filers or $315,000 for married filers. For the majority of New Mexicans in lower and middle income brackets, the effective rate is considerably lower.
Two changes in 2023 significantly improved New Mexico’s attractiveness for retirees: the state enacted a broad Social Security exemption for individuals earning under $100,000 (married: $150,000), and military retirement pay became fully exempt. New Mexico has also long been recognized as a low-cost, warm-climate retirement destination offering a genuine quality-of-life value proposition compared to neighboring Arizona and Texas.
New Mexico’s approach to consumption taxes is unique: rather than a standard sales tax, the state uses a Gross Receipts Tax (GRT) that is technically levied on businesses rather than on individual consumers at the point of sale. In practice, the cost is typically passed to consumers, but the legal distinction matters for businesses and creates some different exemption patterns than a standard sales tax. This guide covers all major New Mexico taxes for workers, retirees, and business owners.
Section 01
New Mexico Income Tax: Progressive Brackets and the 2021 High-Earner Rate
New Mexico’s Five-Bracket Progressive System
New Mexico uses a progressive income tax with five brackets. For single filers in 2025, the brackets are approximately:
1.7%: Up to $5,500
3.2%: $5,501 to $11,000
4.7%: $11,001 to $16,000
4.9%: $16,001 to $210,000
5.9%: Over $210,000
For married filing jointly, the brackets are wider, with the 5.9% top rate applying above $315,000. The vast majority of New Mexico taxpayers fall in the 4.7–4.9% brackets for most of their income. The 5.9% rate was added by the legislature in 2021 as part of a revenue package and affected only the highest earners.
The 2021 Top Rate: Context and Impact
New Mexico’s 5.9% top rate is competitive with, though slightly above, neighboring states like Colorado (4.4% flat) and Utah (4.55% flat). It is, however, dramatically lower than California (top rate 13.3%) and well below Minnesota (top rate 9.85%). For the typical New Mexico resident earning $60,000–$100,000, the effective state income tax rate — total tax divided by total income — is typically 3.5–4.5%, making New Mexico moderately competitive in the region.

Estimates approximate after standard deductions. Actual amounts vary based on filing status, deductions, and specific bracket thresholds. Arizona moved to a flat 2.5% rate in 2023.
New Mexico Standard Deduction and Modifications
New Mexico allows a deduction equal to the federal standard deduction or federal itemized deductions, whichever is higher — making New Mexico’s starting point fairly aligned with federal taxable income. New Mexico then applies its own additions and subtractions, most notably the retirement income and Social Security exemptions discussed below.
Section 02
The Gross Receipts Tax: New Mexico’s Unique Consumption Tax
What Makes New Mexico Different
Unlike every other US state, New Mexico does not have a traditional sales tax levied on the consumer. Instead, New Mexico imposes a Gross Receipts Tax (GRT) on the “privilege of doing business” in the state. The GRT is legally a tax on the seller — the business — not on the buyer. However, businesses are expressly permitted to pass the GRT cost to consumers separately on invoices and receipts, and virtually all do. The practical effect for most everyday purchases is similar to a sales tax: you pay more at the register.
GRT Rates by Location
The state GRT rate is 5.125%. Municipalities and counties can add local increments on top of this:
Albuquerque: 5.125% state + 2.75% local = 7.875% combined
Santa Fe: 5.125% state + 3.3125% local = 8.4375% combined
Las Cruces: 5.125% state + 2.5% local = 7.625% combined
Rio Rancho: 5.125% state + 2.625% local = 7.75% combined
Farmington: 5.125% state + 3.1875% local = 8.3125% combined
What’s Different Under GRT vs. a Standard Sales Tax
Several categories work differently under the GRT than under a traditional sales tax:
Services: Many professional services (legal, accounting, consulting) that would not be subject to sales tax in other states ARE subject to GRT in New Mexico, because the GRT applies to gross receipts from all business activity
Prescription drugs: Exempt from GRT
Groceries: Certain food items have a reduced GRT rate or exemption under New Mexico law, though the rules are more complex than a simple grocery exemption
Medical services: Healthcare services provided by licensed practitioners are generally exempt
Manufacturing: Manufacturers may deduct certain inputs from their GRT base, providing relief similar to other states’ manufacturing exemptions
Property Tax: Moderate with Unique Exemptions
New Mexico’s effective property tax rate of approximately 0.80% of market value is moderate — below the national average but above the lowest-rate western states. Property is assessed at one-third of market value for residential property; the millage rate then applies to this assessed value. The Head of Family exemption provides a $2,000 reduction in taxable value (applied to assessed value, not market value) for heads of household on their primary residence. New Mexico also provides a veterans’ exemption of $4,000 reduction in taxable value for qualifying veterans and an additional low-income valuation freeze for seniors.
Section 03
Retirement Income, Social Security Exemption, and New Mexico as a Retirement Destination
The 2023 Social Security Exemption: A Major Shift
Until 2022, New Mexico taxed Social Security benefits as ordinary income — one of just a handful of states that did so with no income-based limitation. This was a significant deterrent for retirees considering New Mexico. In 2023, the legislature enacted a broad Social Security exemption:
Single filers: Social Security is fully exempt if AGI is $100,000 or less
Married filing jointly: Social Security is fully exempt if AGI is $150,000 or less
Above those thresholds: Social Security benefits are included in taxable income as before
For the vast majority of New Mexico retirees, this exemption eliminates Social Security from the state income tax calculation entirely. A retired couple with $80,000 in AGI (including Social Security, pension, and investment income) now owes no New Mexico income tax on their Social Security benefits. This change, combined with military retirement exemptions added in the same period, has made New Mexico substantially more competitive for retirees.
New Mexico Pension and Retirement Income Tax Treatment
Military retirement pay: Fully exempt from New Mexico income tax (enacted 2022)
New Mexico Public Employees’ Retirement Association (PERA): Pension income fully exempt
Educational Retirement Board (ERB) — for NM teachers: Pension income fully exempt
Federal civil service pensions (CSRS/FERS): Taxable — no blanket exemption; higher-income federal retirees will owe New Mexico income tax on federal pension income
Private pensions, IRA, and 401(k) distributions: Taxable at standard progressive rates
New Mexico as a Retirement Destination
New Mexico has several structural advantages for retirees considering the Mountain West:
Low cost of living: Housing, groceries, and services are generally less expensive than neighboring Colorado or Arizona cities
Warm climate: Southern New Mexico (Albuquerque, Las Cruces) offers significantly warmer winters than Colorado or northern states
Cultural richness: Santa Fe and Taos are nationally recognized arts and culture destinations with active retiree communities
Proximity to Texas and Arizona: Major cities in all three neighboring states are within driving distance for family visits or specialized medical care

Compared to Arizona, New Mexico’s income tax is somewhat higher for middle-to-upper earners. However, New Mexico’s lower housing costs in cities like Albuquerque and Las Cruces — and the state’s generous exemptions for Social Security (below the income threshold) and government pensions — can make the overall cost of retirement in New Mexico competitive or superior depending on individual circumstances.

New Mexico has a progressive income tax with five brackets: 1.7%, 3.2%, 4.7%, 4.9%, and 5.9%. The 5.9% top rate applies only to income above $210,000 for single filers or above $315,000 for married filing jointly. Most New Mexico residents earning $60,000–$150,000 will have a 4.7–4.9% marginal rate on most of their income, with an effective rate typically between 3.5% and 4.5%.
Q
Does New Mexico tax Social Security benefits?
As of 2023, New Mexico exempts Social Security benefits for single filers with AGI of $100,000 or less, and for married filers with AGI of $150,000 or less. If your income exceeds these thresholds, Social Security benefits are included in New Mexico taxable income at the standard progressive rates. This 2023 change was a significant improvement from prior law, when New Mexico taxed all Social Security with no income-based exemption.
Q
What is New Mexico’s Gross Receipts Tax and how is it different from a sales tax?
New Mexico’s Gross Receipts Tax (GRT) is legally a tax on businesses for the privilege of conducting business in New Mexico, rather than a tax on the consumer at the point of sale. The state GRT rate is 5.125%, with local additions bringing combined rates to approximately 7.875% in Albuquerque and 8.4375% in Santa Fe. Businesses can separately state and pass the GRT to consumers, so in practice it works similarly to a sales tax. One key difference: GRT applies to many professional services that would not be taxed under a traditional sales tax in other states.
Q
Is military retirement pay taxed in New Mexico?
No. New Mexico fully exempts military retirement pay from state income tax as of 2022. New Mexico Public Employees’ Retirement Association (PERA) and Educational Retirement Board (ERB) pension income for state and local government employees and teachers is also fully exempt. Federal civil service pensions (CSRS/FERS) are taxable at the standard progressive rates.
Q
What is the property tax rate in Albuquerque?
New Mexico’s effective property tax rate averages approximately 0.80% of market value statewide. In Albuquerque (Bernalillo County), a $300,000 home typically generates an annual property tax bill of approximately $2,000–2,600/year. New Mexico assesses residential property at one-third of market value before applying millage rates. The Head of Family exemption provides a $2,000 reduction in taxable assessed value for heads of household on their primary residence.
Q
Does New Mexico have an estate tax or inheritance tax?
No. New Mexico has no state estate tax and no inheritance tax. Assets inherited from New Mexico residents are not subject to any New Mexico state-level transfer tax. The federal estate tax may apply to very large estates exceeding the federal exemption threshold, but New Mexico imposes no additional state tax.
Q
Is New Mexico a good state for retirees from a tax perspective?
New Mexico has become significantly more competitive for retirees after the 2022–2023 reforms. Key advantages: Social Security is now exempt for most income levels (under $100k single/$150k married), military retirement is fully exempt, and PERA/ERB state pensions are exempt. Property taxes are moderate at ~0.80%. The main drawback is the progressive income tax reaching 5.9% for higher earners and the GRT rates of 7.5–9.3% on purchases. For retirees with government pensions or Social Security as their primary income sources, the combined picture is genuinely favorable, especially when combined with New Mexico’s lower overall cost of living compared to Colorado or Arizona.
