If you live, work, or run a business in New Mexico, you’ll deal with four main taxes: a personal income tax that runs from 1.7% to 5.9%, a gross receipts tax that replaces the traditional sales tax and typically falls between about 5.25% and 9% depending on where you are, property tax calculated on one-third of your home’s market value, and — for incorporated businesses — a corporate income tax of 4.8% to 7.6%. The taxes you pay in New Mexico depend on your income, your location, what you buy, and what you own, so the sections below walk through each one in turn.
Personal Income Tax
New Mexico’s Income Tax Act taxes everyone who lives in or earns money in the state.1Justia Law. New Mexico Code 7-2-1 – Short Title Full-year residents owe tax on all their income no matter where it was earned. Part-year residents and nonresidents owe tax only on income earned from New Mexico sources while they lived or worked here.
There are five brackets. The lowest rate of 1.7% applies to the first slice of taxable income, then rates step up through 3.2%, 4.7%, and 4.9% before reaching the top rate of 5.9%.2New Mexico Legislature. New Mexico Personal Income Tax – A Brief History and Review of Selected Provisions That top rate kicks in at $315,000 for married couples filing jointly, $210,000 for single filers, and $157,500 for married individuals filing separately. Only the income above each threshold gets taxed at the higher rate, so higher earners still pay the lower rates on their first dollars.
New Mexico’s standard deduction matches the federal standard deduction dollar for dollar.3New Mexico Legislature. Fiscal Impact Report – HB0093 Your state taxable income starts with your federal adjusted gross income, then gets reduced by whichever deduction you take plus any state-specific adjustments.
Social Security Income
If your Social Security benefits are included in your adjusted gross income, you can exempt them from New Mexico tax when your AGI falls below $100,000 for single filers, $150,000 for married couples filing jointly, or $75,000 for married individuals filing separately.4New Mexico Legislature. SB-156 Bill Analysis and Fiscal Impact Report Below those caps, the deduction is total. Legislation has been introduced to remove the caps entirely for tax years beginning in 2026, so confirm the current rule with the Taxation and Revenue Department before you file.
Gross Receipts Tax
New Mexico does not have a traditional sales tax. In its place is the gross receipts tax, which the state imposes on businesses for the privilege of doing business here. Legally the tax falls on the seller, not the buyer, but nearly every business passes it along as a separate line on your receipt. The distinction still matters because the obligation to report and pay rests entirely with the business.
The state base rate is 4.875%. Counties and cities layer their own increments on top, so the total rate you actually see on a receipt depends on the location of the transaction. In some rural unincorporated areas the combined rate stays around 5.25%, while locations with multiple special taxing districts push past 9%, and a few areas with overlapping local levies reach roughly 10.8%.5Sierra County, New Mexico. Gross Receipts and Compensating Tax Rate Schedule – Effective July 1, 2025 Through June 30, 2026
What It Covers
The gross receipts tax applies broadly: tangible goods, services, leases, and certain licensing arrangements. Where most states exempt a long list of services, New Mexico taxes nearly all of them. Haircuts, legal fees, plumbing repairs, and most other professional and labor-based services generally carry the tax.
Some categories do get deductions or exemptions. Prescription drugs, oxygen and related medical equipment services, and many healthcare services billed through Medicare or TRICARE can be deducted from a provider’s gross receipts.6New Mexico Legislature. Gross Receipts Taxation and Healthcare Dozens of other statutory deductions exist, so businesses should check the full list for anything that fits their activity.
Late Filing Penalties
A business that files or pays its gross receipts tax late is assessed a penalty of 2% of the unpaid tax for each month or partial month the return is late, up to a maximum of 20%.7NM Taxation & Revenue Department. Penalty Interest Rates Interest accrues separately on the unpaid balance. The same penalty structure applies to every tax the department administers.
Compensating Tax on Out-of-State Purchases
The compensating tax is the companion to the gross receipts tax for things you buy from out of state. If you purchase tangible goods from an out-of-state seller who didn’t collect New Mexico gross receipts tax, and you use those goods in New Mexico, you owe compensating tax on their value. The state rate mirrors the 4.875% base, and the same local increments apply based on where the property is used.5Sierra County, New Mexico. Gross Receipts and Compensating Tax Rate Schedule – Effective July 1, 2025 Through June 30, 2026 Many online retailers now collect this automatically, but if you’re a business buying equipment or supplies from an out-of-state vendor, check whether the tax was already collected at the point of sale.
Property Tax
Property tax is administered at the county level under statewide rules. The taxable value of any property is one-third of its full market value.8Justia Law. New Mexico Code 7-37-1 – Short Title The county assessor sets the market value, applies the one-third ratio to get the taxable value, and multiplies that by the local mill rate (one mill equals one dollar per thousand dollars of taxable value) to produce your bill.
The 3% Cap for Homeowners
Owner-occupied single-family homes get a 3% annual cap on valuation increases.9New Mexico Department of Finance and Administration. Yield Control Formula Even if the housing market pushes your home’s actual market value up 10% in a single year, the assessed value used for tax purposes can only rise 3%. The cap resets when the property changes hands, and the new owner’s assessment starts fresh at full market value.
When It’s Due
Property taxes come in two installments. The first half is due November 10 and the second half by April 10 of the following year.10NM Taxation & Revenue Department. Important Dates – Property Tax Division You can also pay the full year at once by the November 10 deadline. The money funds local schools, roads, emergency services, and other county and municipal needs.
Corporate Income Tax
Corporations doing business in New Mexico pay a separate corporate income tax on net taxable income. For tax years beginning on or after January 1, 2026, the rates are:
- 4.8% on the first $500,000 of taxable income
- 6.4% on taxable income between $500,001 and $1,000,000
- 7.6% on taxable income above $1,000,00011New Mexico Legislature. SB0211 – Decreasing the Gross Receipts Tax Rate and the Compensating Tax Rate
S-corporations, partnerships, and LLCs that are treated as pass-through entities for federal purposes generally pass their income through to the individual owners, who then report it on their personal New Mexico returns.
Credits That Can Lower What You Owe
Several credits and rebates are designed to reduce the tax burden on lower- and middle-income residents.
Working Families Tax Credit
The Working Families Tax Credit is a refundable credit worth 25% of the federal Earned Income Tax Credit you claim on your federal return.12New Mexico Legislature. Agency Bill Analysis – HB0296 Because it’s refundable, you get the full amount even if it exceeds the state tax you owe. The credit is larger for families with more dependents and phases out as income rises, mirroring the federal EITC. Legislation has been proposed to raise this credit to 50% starting in 2026, so confirm the rate with the Taxation and Revenue Department before you file.
Low Income Comprehensive Tax Rebate
Residents with a modified gross income of $36,000 or less may qualify for the Low Income Comprehensive Tax Rebate, which is meant to offset the gross receipts tax burden that falls hardest on lower-income households. You have to be a New Mexico resident for the full year to claim it, and you apply for it on your PIT-1 return.
Filing Your Return and Key Deadlines
Personal income tax returns are due April 15 each year.13NM Taxation & Revenue Department. New Mexico to Begin Accepting Electronic Income Tax Returns Jan. 16 If April 15 lands on a weekend or holiday, the deadline moves to the next business day. You can request an automatic six-month filing extension, but any tax you owe is still due by the original April 15 date to avoid penalties and interest. Businesses that collect gross receipts tax file and pay either monthly or quarterly, depending on how much they take in.
Individual residents file on form PIT-1, the standard New Mexico personal income tax return.14NM Taxation & Revenue Department. Personal Income Tax Forms You’ll need your federal adjusted gross income from your federal return, Social Security numbers for yourself and any dependents, residency dates if you moved during the year, and documentation for any credits or deductions you’re claiming.
The simplest way to file and pay is through the Taxpayer Access Point, known as TAP.15State of New Mexico: Taxation & Revenue Department. Taxpayer Access Point TAP lets you submit returns, make payments, check refund status, and manage multiple tax accounts — income tax, gross receipts tax, withholding, and others — from one login.16NM Taxation & Revenue Department.

Electronic filing generally produces faster refunds than paper.
