New Mexico Income Tax: Graduated Brackets Up to 5.9%
New Mexico uses a progressive income tax system with 6 brackets under HB 252 (in force since 2025). Rates range from 1.5% to 5.9%, with higher income taxed at higher rates. New Mexico taxable income is federal AGI minus the federal standard or itemized deduction, minus a low- and middle-income exemption of up to $2,500 per exemption for lower incomes. New Mexico exempts most Social Security income from state taxation.
Like federal taxes, New Mexico's system is marginal — only the income within each bracket is taxed at that bracket's rate. Combined with federal taxes (10%–37%), New Mexico residents can face a total marginal rate of up to 42.9% on their highest dollars of income.
New Mexico Tax Brackets for 2026 (Single Filer)
The New Mexico income tax brackets for single filers are:
- 1.5% on taxable income from $0 to $5,500
- 3.2% on taxable income from $5,500 to $16,500
- 4.3% on taxable income from $16,500 to $33,500
- 4.7% on taxable income from $33,500 to $66,500
- 4.9% on taxable income from $66,500 to $210,000
- 5.9% on taxable income over $210,000
Example: a single filer earning $60,000 has New Mexico taxable income of $43,900 after the $16,100 standard deduction and owes about $1,654 (2.8% of gross income). Your marginal rate is the rate on your last dollar of income. Your effective rate (total tax divided by total income) is always lower because of the progressive structure.
Tips to Lower Your New Mexico Tax
Maximize pre-tax retirement contributions to reduce both federal and New Mexico taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). New Mexico allows the federal standard or itemized deduction, so lowering federal taxable income lowers New Mexico tax too. This calculator ignores New Mexico dependent deductions and credits.
Tips for Getting Accurate Results
For the most accurate results, use up-to-date numbers from official sources. Double-check your inputs before calculating — small errors in the starting values can lead to significantly different outputs. If you are comparing scenarios, keep all variables the same except the one you are testing. Save or screenshot your results for future reference. This calculator uses standard formulas and is designed to give you a reliable quick estimate, though professional advice may be needed for complex situations.
