New Mexico State Tax Rate Guide – New Mexico offers one of the more competitive tax environments in the U.S., with relatively low property taxes and targeted relief for seniors, veterans, and low-income families. Whether you’re a resident filing your 2025 taxes in 2026, a business owner, or considering a move to the Land of Enchantment, this New Mexico state tax rate guide provides the latest, official rates and rules. All information is current as of April 2026 and drawn from trusted sources including the New Mexico Taxation and Revenue Department (TRD), the Tax Foundation, and AARP.
Overview of New Mexico Taxes
New Mexico uses a graduated individual income tax, a gross receipts tax (GRT) instead of a traditional sales tax, and low property taxes. The state has no estate or inheritance tax, making it attractive for retirees and families. Rates vary by filing status, income level, and location, but New Mexico consistently ranks favorably for overall tax burden compared to many other states.
Key taxes covered in this guide:
- Individual income tax (1.5%–5.9%)
- Gross receipts tax (state base 4.875% + local)
- Property tax (average effective rate 0.63%)
- Corporate income tax (flat 5.9%)
New Mexico Individual Income Tax Rates and Brackets
New Mexico imposes a graduated personal income tax with six brackets ranging from 1.5% to 5.9%. Taxable income starts with your federal adjusted gross income (AGI), and New Mexico largely conforms to federal rules.
Here are the 2026 tax brackets (unchanged from recent years following 2025 adjustments that added a new middle bracket for middle-income relief):
Single Filers
| Taxable Income | Rate |
|---|---|
| $0 – $5,500 | 1.5% |
| $5,501 – $16,500 | 3.2% |
| $16,501 – $33,500 | 4.3% |
| $33,501 – $66,500 | 4.7% |
| $66,501 – $210,000 | 4.9% |
| Over $210,000 | 5.9% |
Married Filing Jointly / Head of Household
| Taxable Income | Rate |
|---|---|
| $0 – $8,000 | 1.5% |
| $8,001 – $25,000 | 3.2% |
| $25,001 – $50,000 | 4.3% |
| $50,001 – $100,000 | 4.7% |
| $100,001 – $315,000 | 4.9% |
| Over $315,000 | 5.9% |
Married Filing Separately
Brackets are roughly half of joint filers (e.g., top bracket starts over $157,500 at 5.9%).
Important notes:
- You may claim the federal standard deduction ($15,750 single / $31,500 joint for 2025 returns filed in 2026, subject to inflation adjustment) or itemize.
- Social Security benefits are fully exempt for lower- and middle-income filers (AGI under $100,000 single / $150,000 joint).
- Retirement income deduction up to $8,000 for those 65+ or blind.
- Active-duty military pay is exempt; military pensions exempt up to $30,000.
Low-income residents may qualify for rebates. Always use the official TRD tax lookup tables for precise calculations.
New Mexico Gross Receipts Tax (GRT) – The State’s “Sales Tax”
New Mexico does not have a traditional sales tax. Instead, businesses pay a Gross Receipts Tax (GRT) on most goods and services, which is typically passed on to consumers.
- State base rate: 4.875%
- Combined state + local rates: Range from 5.25% to 9.44% depending on city and county (highest in Taos Ski Valley at 9.4375%).
- Average combined rate across the state is approximately 7.67%.
The GRT applies to both tangible goods and most services—unlike many states. Out-of-state sellers must collect compensating (use) tax at the same rate as the destination location. Most groceries, prescription drugs, and gasoline are exempt. New Mexico also offers an annual three-day GRT holiday (July 31–August 2, 2026) for back-to-school clothing, computers, and supplies.
Businesses register with the TRD and use the official Gross Receipts Location Code and Tax Rate Map to determine the exact rate by address.
New Mexico Property Tax Rates
New Mexico has some of the lowest property taxes in the nation.
- Average effective rate: 0.63% of assessed home value (one of the lowest in the U.S.).
- Median annual property tax paid: approximately $1,043–$1,776 depending on county and home value.
Property is assessed at one-third of market value, then multiplied by local mill rates set by counties, cities, and school districts. Rates vary significantly:
- Highest median taxes: Los Alamos County (~$2,717)
- Lowest: Harding County (~$305)
Exemptions and relief:
- $2,000 head-of-household exemption on primary residence
- Up to $10,000 for veterans
- Disabled veterans: up to 100% exemption
- Age 65+ and disabled: property value freeze (if income ≤ $44,200) and possible rebate up to $250 (or more in select counties)
New Mexico Corporate Income Tax Rates
In 2025, New Mexico simplified its corporate income tax to a flat 5.9% rate on all corporate income (previously graduated). This change made the state more predictable for businesses while keeping the rate competitive nationally.

- Gas tax: Approximately 17–18.88 cents per gallon (regular gasoline); special fuels 21 cents
