New Mexico tax rates run across several separate systems: a personal income tax with six brackets from 1.5% to 5.9%, a flat 5.9% corporate income tax, a gross receipts tax that typically lands between 5% and just over 9% depending on location, county-administered property tax applied to one-third of a home’s assessed value, and targeted excise taxes on cigarettes, motor fuel, cannabis, and alcohol. Each one works differently, and the rate that matters to you depends on what you earn, what you buy, and what you own.
Personal Income Tax Brackets
Individual income tax is progressive, with rates climbing through six brackets. For single filers:1Justia. New Mexico Code 7-2-7 – Individual Income Tax Rates
- Up to $5,500: 1.5%
- $5,501 to $16,500: 3.2%
- $16,501 to $33,500: 4.3%
- $33,501 to $66,500: 4.7%
- $66,501 to $210,000: 4.9%
- Over $210,000: 5.9%
Joint filers and heads of household get wider brackets at every tier, with the top 5.9% rate kicking in above $315,000 for married couples filing jointly. Married couples filing separately have brackets roughly half the size of the joint brackets. The rates themselves are identical across filing statuses; only the thresholds move.
Residents owe tax on all income no matter where it was earned. Nonresidents owe only on income from property, employment, or business activity inside New Mexico, and part-year residents pay on income attributable to the time they lived in the state.2Justia. New Mexico Code 7-2-3 – Imposition and Rate of Tax The state generally follows federal definitions for adjusted gross income.
Social Security and Retirement Income
Most Social Security benefits escape state income tax. Single filers earning under $100,000 and joint filers under $150,000 owe nothing on their Social Security. The threshold for married couples filing separately is $75,000.3NM Taxation & Revenue Department. Social Security Income Tax Exemption Above those lines, a portion of benefits can be taxed.
Military retirees can exclude up to $30,000 of military retirement pay from state taxable income, and disability retirement pay for service-connected injuries is fully excluded. Private-sector pension income is generally taxed at the normal individual rates.
Gross Receipts Tax Rates
New Mexico does not have a traditional sales tax. The gross receipts tax falls on businesses for the privilege of operating in the state and is calculated on their total receipts.4New Mexico Legislature. Overview of New Mexico Gross Receipts and Compensating Tax Act Most businesses pass it through as a line item, so it looks and feels like sales tax at the register.
The rate on a receipt combines the state base with local add-ons from the county and municipality where the transaction is sourced. Combined rates generally run from 5% to just over 9%. Albuquerque, Santa Fe, and Las Cruces each sit at different combined rates, so the same purchase costs slightly more or less depending on where you make it.
Since July 2021, most transactions use destination-based sourcing. The rate is set by where goods are delivered or where the product of a service is received, not where the seller is located.5NM Taxation & Revenue Department. New Gross Receipts Tax Rules Take Effect July 1 An Albuquerque firm doing work for a Taos client charges the Taos rate.
Certain goods are deductible from gross receipts and effectively untaxed. Groceries sold at qualifying retail food stores fall under Section 7-9-92, covering most staple food items for home consumption. Hot prepared food, restaurant meals, alcohol, and tobacco do not qualify. Prescription drugs are also deductible under a separate provision.
Corporate Income Tax Rate
Corporate income is taxed at a flat 5.9%. A 2024 legislative change replaced the previous two-tier structure (4.8% on income under $500,000, 5.9% above) with the single flat rate, effective for tax years beginning January 1, 2025.6Justia. New Mexico Code 7-2A-5 – Corporate Income Tax Rates A corporation earning $100,000 now pays the same rate as one earning $10 million. Corporations doing business in New Mexico also owe franchise tax, filed on the same return.
Property Tax and the One-Third Rule
Property tax is administered at the county level, and the key feature is that only 33.33% of a property’s assessed value is subject to tax.7Justia. New Mexico Code 7-37-3 – Tax Ratio Established A home assessed at $300,000 has a taxable value of $100,000 before any exemptions. The actual mill rate applied to that taxable value is set locally.
Homeowner and Veteran Exemptions
The head-of-family exemption cuts taxable value by $2,000 for a New Mexico resident who owns and occupies a home as the head of a household.8Justia. New Mexico Code 7-37-4 – Head-of-Family Exemption
Veterans get a $4,000 exemption from taxable value, and it extends to an unmarried surviving spouse.9New Mexico Legislature. Veteran Property Tax Exemption Disabled veterans receive an additional percentage-based exemption equal to their federal disability rating applied to the remaining taxable value, which can zero out the property tax for veterans rated 100% disabled.10Justia. New Mexico Code 7-37-5.1 – Disabled Veteran Exemption
The 3% Annual Cap
Residential taxable value cannot climb more than 3% in a single year under Section 7-36-21.2.11Justia. New Mexico Code 7-36-21.2 – Limitation on Increases in Valuation of Residential Property The cap resets when a home sells (the new owner’s value starts fresh at current market value), when significant improvements are made, or when zoning changes. Non-residential property gets no cap at all.
Excise Tax Rates
Cigarettes carry a state excise tax of 10 cents per cigarette, or $2.00 per standard pack of twenty.12Justia. New Mexico Code 7-12-3 – Excise Tax on Cigarettes
Motor fuel is taxed at a base rate of 17 cents per gallon, with additional surtaxes bringing the total state gasoline tax to roughly 18.9 cents per gallon. Those funds support road construction and maintenance.
Cannabis sold at retail is subject to the cannabis excise tax, which climbs on a set schedule. The rate is 13% from July 2025 through June 2026, rises to 14% in July 2026, and continues up one percentage point each year until it reaches 18% in July 2030.13NM Taxation & Revenue Department. Cannabis Excise Tax Retail cannabis sales also owe the regular gross receipts tax on top, so the real tax load is well above the excise rate alone.
Alcohol is taxed at per-unit rates that vary by type and volume, with spirits carrying the highest rate, beer the lowest, and wine in between.
Filing Deadlines and Late Penalties
Individual income tax returns are due April 15, matching the federal deadline. The state’s Taxpayer Access Point (TAP) handles electronic filing and payment and confirms receipt immediately. Paper returns are still accepted but process more slowly.
An extension using Form RPD-41096 buys more time to file but not more time to pay. Any tax you owe is still due April 15, and unpaid balances start accruing penalties right away.
The late-filing or late-payment penalty is 2% per month (or any fraction of a month) on the unpaid balance, capped at 20% of the total tax due.14Justia. New Mexico Code 7-1-69 – Civil Penalty for Failure to Pay Tax or File a Return Interest runs on top of the penalty. The cleanest way to avoid both is to pay your best estimate by April 15 even if the finished return comes later.
