New Mexico taxes wage income at rates up to 5.9 percent
Yes, New Mexico has a state income tax. The state taxes wages, salaries, interest, dividends, and other forms of income. The tax rate depends on your filing status and total income, ranging from 1.7 percent to 5.9 percent. Unlike some states, New Mexico does not exempt retirement income or Social Security from taxation, though certain deductions and credits can reduce what you owe.
If you work in New Mexico or live there, you will file a state return in addition to your federal return. The state uses a progressive tax system, meaning higher earners pay a higher percentage. Your employer typically withholds state tax from your paycheck based on the W-4 information you provide.

- The state taxes wages, investment income, and retirement distributions, including Social Security in some cases.

How New Mexico's tax brackets work
New Mexico uses tax brackets that change each year. The lowest bracket starts at 1.7 percent and applies to the first portion of your income. As your income rises, you move into higher brackets with higher rates, up to the top rate of 5.9 percent. The exact income thresholds that trigger each bracket vary by filing status—single, married filing jointly, married filing separately, and head of household each have different breakpoints.
For example, a single filer in 2024 might pay 1.7 percent on the first $5,900 of taxable income, then 3.2 percent on income between $5,900 and $11,800, and so on. A married couple filing jointly would have higher thresholds before entering each bracket. The state updates these brackets annually to account for inflation, so the exact numbers change year to year. You can find the current brackets on the New Mexico Department of Revenue website or on your state tax form instructions.
What income is taxed and what is not
New Mexico taxes most types of income: W-2 wages, self-employment income, interest, dividends, capital gains, rental income, and distributions from retirement accounts. Social Security benefits are taxable in New Mexico if your combined income exceeds certain thresholds, unlike some other states that exempt Social Security entirely. Pension income and distributions from IRAs and 401(k)s are also subject to tax.
Some income is excluded. Municipal bond interest is not taxed. Certain military benefits and combat zone pay are excluded. Gifts and inheritances are not taxed as income. If you receive workers' compensation or unemployment benefits, those are taxable in New Mexico. The key is to review your specific situation, because the rules differ depending on the source of the money.
Deductions and credits that lower your tax bill
You can reduce your New Mexico taxable income using either the standard deduction or itemized deductions, just as you do on your federal return. The standard deduction amount varies by age and filing status and changes annually. If you are 65 or older, you receive an additional standard deduction. Many taxpayers use the standard deduction because it is simpler than itemizing.
New Mexico also offers tax credits that directly reduce the tax you owe. The state has a dependent exemption credit, a working families tax credit for lower-income earners, and credits for education expenses. Some credits are refundable, meaning you can receive money back even if you owe no tax. Others are nonrefundable and can only reduce your tax liability to zero. Credits are often more valuable than deductions because they reduce your tax dollar-for-dollar rather than reducing your taxable income.
What happens if you work in New Mexico but live elsewhere
If you live in a neighboring state but work in New Mexico, you typically owe tax to New Mexico on the income you earn there. New Mexico taxes residents on all income and nonresidents on income earned within the state. This means you may file returns in both states. However, most states offer a credit for taxes paid to another state to prevent double taxation. You would claim a credit on your home state's return for the New Mexico tax you paid.
The credit usually equals the lesser of the tax you paid to New Mexico or the tax your home state would have charged on that same income. If New Mexico's tax rate is higher, you may still owe your home state the difference. If your home state's rate is higher, the credit covers the full New Mexico tax and you owe only your home state. The mechanics vary by state, so review both states' instructions or consult a tax professional if you work across state lines.
How to file your New Mexico state return
You file your New Mexico return using Form PIT (Personal Income Tax Return) or a simplified form if your situation is straightforward. The form asks for your income from all sources, deductions, credits, and withholding information. You must report your federal adjusted gross income as a starting point, then make any New Mexico-specific adjustments. The state provides detailed instructions with the form.
You can file by mail, electronically through the state's website, or through tax software that supports New Mexico returns. If you owe tax, payment is due by April 15 unless you file for an extension. If you overpaid through withholding, you will receive a refund. The state processes returns and issues refunds, though timing varies. If you miss the important date, penalties and interest accrue on unpaid tax, so filing on time or requesting an extension before the important date is important.
Withholding and estimated tax payments
Your employer withholds New Mexico state tax from your paycheck based on the W-4 form you complete. The withholding is an estimate of your annual tax liability. If too much is withheld, you receive a refund when you file. If too little is withheld, you owe when you file. You can adjust your withholding by submitting a new W-4 to your employer if your situation changes—for example, if you get married, have a child, or take a second job.
If you are self-employed or have income not subject to withholding, you may need to make quarterly estimated tax payments to New Mexico. These are due on April 15, June 15, September 15, and January 15. Underpayment penalties explore if you do not pay enough throughout the year. The state provides a worksheet to calculate your estimated payment. If your income is uneven or unpredictable, you can adjust your payments each quarter based on actual earnings.
Frequently Asked Questions
Does New Mexico tax Social Security?
Social Security is taxable in New Mexico if your combined income (adjusted gross income plus nontaxable interest plus half of Social Security benefits) exceeds $25,000 for single filers or $32,000 for married couples filing jointly. If you are below those thresholds, your Social Security is not taxed. If you are above them, up to 85 percent of your benefits may be subject to tax.
Can I deduct federal income tax paid on my New Mexico return?
No. New Mexico does not allow a deduction for federal income tax paid. However, you can deduct state and local taxes (SALT) on your federal return, subject to the $10,000 annual cap. New Mexico state income tax is one of the taxes you can include in that federal deduction.
What is the important date to file my New Mexico return?
The important date is April 15 unless that date falls on a weekend or holiday, in which case it moves to the next business day. You can request an automatic extension to October 15 by filing Form PIT-EXT before the April important date. An extension gives you more time to file but does not extend the time to pay; tax owed is still due by April 15 or penalties explore.
Do I have to file a New Mexico return if I live there part of the year?
If you are a resident for any part of the tax year, you must file a New Mexico return on all income earned during the time you were a resident. If you moved to New Mexico mid-year, you report income for the full year but may claim a credit for taxes paid to your previous state. The state considers you a resident if you maintain a home there or spend more than 183 days there during the year.
What if I did not have enough tax withheld and cannot pay the full amount?
Contact the New Mexico Department of Revenue to discuss payment options. The state may allow you to set up a payment plan to pay your balance over time. Interest and penalties continue to accrue on unpaid tax, so paying as soon as possible reduces the total amount you owe. Filing your return on time, even if you cannot pay when ready, is important to minimize penalties.
