New Mexico does have a state income tax
New Mexico taxes wages, salaries, business income, and most other forms of earned and unearned income. The state income tax rate ranges from 1.7% to 5.9% depending on your income bracket, and it applies to both residents and nonresidents who earn money in the state. If you work in New Mexico or live there, you will owe state income tax unless you fall into a narrow category of exemptions.
The state also taxes capital gains, dividends, and interest income at the same rates as ordinary income. Unlike some states that tax only certain types of income, New Mexico's approach is broad: most money you receive is taxable unless a specific law carves out an exception.

Who has to file a New Mexico tax return
You must file a New Mexico return if you are a resident with income above the filing threshold, or a nonresident who earned income in the state. Residency for tax purposes generally means you lived in New Mexico for more than half the tax year, or you maintained a permanent home there and spent more than 30 days in the state during the year.
The filing threshold depends on your age and filing status. For 2024, a single person under 65 must file if their gross income exceeds $13,850; a single person 65 or older has a higher threshold. Married couples filing jointly have different thresholds based on whether one or both spouses are 65 or older. These thresholds change annually, so check the New Mexico Department of Revenue website for the current year's amounts.
Nonresidents who earned wages, self-employment income, or business income in New Mexico must file even if they do not meet the resident threshold, because the state taxes income earned within its borders regardless of where you live.
Tax brackets and rates for 2024
New Mexico uses a progressive tax system with five tax brackets. The lowest rate is 1.7% on the first portion of taxable income, and the highest is 5.9% on income above a certain level. The exact bracket thresholds depend on your filing status—single, married filing jointly, married filing separately, or head of household—and they are adjusted each year for inflation.
For example, a single filer in 2024 pays 1.7% on income up to roughly $6,000, then 3.2% on the next bracket, and so on, until reaching 5.9% on income above roughly $100,000. A married couple filing jointly has wider brackets at each rate. Because these numbers change annually, use the New Mexico Department of Revenue's tax tables or a tax calculator to find your exact bracket for the year you are filing.
The state also allows a deduction for federal income tax paid in the same year. This deduction can meaningfully lower your New Mexico taxable income, especially if you paid substantial federal tax.
Retirement income and special exemptions
New Mexico offers significant tax breaks for retirement income. Social Security benefits are fully exempt from state income tax. Distributions from IRAs, 401(k)s, 403(b)s, and similar retirement plans are also exempt, as long as you are 55 or older (or 50 or older if you separated from service). This exemption applies to the full amount of your retirement distributions, not just a portion.
Military pensions and federal pensions also receive preferential treatment. Active-duty military pay is completely exempt. Military retirees and federal employees who receive pension income may be able to exclude a portion of that income from taxation, though the rules vary by the type of pension.
In addition, New Mexico exempts certain types of income entirely: interest from U.S. government bonds, income from certain municipal bonds, and income earned by Native Americans on tribal land (subject to specific conditions). If you receive income from any of these sources, you may not owe state tax on it even if you owe federal tax.
How to file your New Mexico return
You can file your New Mexico return on paper using Form PIT-1 (the individual income tax return), or you can file electronically through the state's online system or through tax software that supports New Mexico returns. The state encourages electronic filing and processes e-filed returns faster than paper returns.
Your federal return and your New Mexico return are separate documents, even though they use similar information. You will need your W-2s, 1099s, or other income documents, plus records of any deductions or credits you plan to claim. If you are claiming the federal income tax deduction, you will need your federal return to know the amount.
The filing important date is the same as the federal important date: April 15 of the following year, unless that date falls on a weekend or holiday. If you need more time, you can request an extension, which gives you until October 15 to file (though any tax owed is still due by April 15).
Nonresident income and part-year residents
If you moved to or from New Mexico during the tax year, you are a part-year resident. You owe New Mexico tax only on income earned while you were a resident, and you owe it on all income earned in the state during the months you were a nonresident. This requires careful tracking of when you established or left residency.
Nonresidents who worked in New Mexico for only part of the year still owe tax on that income. For example, if you worked a summer job in New Mexico but live in another state, you owe New Mexico tax on those wages. You will file a nonresident return (Form PIT-1-NR) showing only the income earned in the state.
If you worked remotely for an out-of-state employer while living in New Mexico, the income is generally subject to New Mexico tax because you earned it while a resident. The location of your employer does not matter; what matters is where you were when you earned the income.
Credits and deductions that lower your tax bill
Beyond the federal income tax deduction, New Mexico offers several credits that can reduce your tax liability. The Earned Income Tax Credit (EITC) is available to low- and moderate-income workers and is calculated based on your federal EITC. The state also offers credits for dependent care expenses, education expenses, and certain other situations.
You can also deduct contributions to traditional IRAs, HSAs (Health Savings Accounts), and certain other retirement or savings accounts, which lowers your taxable income before you calculate your tax. These deductions work the same way they do on your federal return.
If you are over 65, you may be may have access to to an additional standard deduction, which increases the amount of income you can exclude from taxation. Check the current year's tax tables to see whether this applies to you.
Frequently Asked Questions
Do I have to pay New Mexico income tax if I just moved there?
You owe New Mexico tax starting the day you become a resident. If you moved mid-year, you are a part-year resident and owe tax only on income earned after you arrived. You will file a part-year resident return showing the date you established residency. Keep documentation of your move—lease, utility bills, or driver's license—to prove when residency began.
Is Social Security taxed in New Mexico?
No. New Mexico fully exempts Social Security benefits from state income tax, regardless of your age or income level. This is one of the most generous Social Security tax treatments in the country. You do not need to report Social Security on your state return.
Can I deduct my federal income tax on my New Mexico return?
Yes. New Mexico allows you to deduct the federal income tax you paid during the same tax year. This deduction is taken on your state return and reduces your New Mexico taxable income. You will need your federal return to know the amount to claim.
What if I worked in New Mexico but lived in another state?
You owe New Mexico income tax on the wages you earned in the state, even if you lived elsewhere. You will file a nonresident return reporting only that income. You may also owe tax to your home state, depending on its rules. Some states offer credits to prevent double taxation, so check both states' rules.
Are military pensions taxed in New Mexico?
Military retirement pay is exempt from New Mexico income tax. Federal pensions and other government pensions receive preferential treatment but may not be fully exempt depending on the type of pension and when you retired. Review the state's pension exemption rules or contact the Department of Revenue if you are unsure whether your specific pension qualifies.
