New Mexico does have a state income tax

New Mexico charges state income tax on wages, self-employment income, and most other earnings. The state tax rate ranges from 1.7% to 5.9% depending on your income bracket, and it applies to residents and part-year residents who earned money in the state. If you work in New Mexico but live in another state, you may owe New Mexico tax on that income.

The state also taxes certain retirement income, including distributions from IRAs and 401(k)s, though there are some exemptions for federal pensions and military retirement pay. Property owners pay property tax to counties and municipalities, not to the state directly, but that is a separate obligation from income tax.

New Mexico income tax brackets and rates for 2024

New Mexico uses a progressive tax system, meaning the rate increases as your income rises. The brackets differ based on whether you file as single, married filing jointly, married filing separately, or head of household. For single filers in 2024, the rates start at 1.7% on income up to $5,900 and reach 5.9% on income over $210,000. Married couples filing jointly have higher income thresholds before entering each bracket.

These brackets adjust each year for inflation, so the dollar amounts change annually. The New Mexico Department of Revenue publishes updated brackets before each tax year. Your actual tax bill depends on which bracket your total income falls into, minus any deductions or credits you claim.

Who has to file a New Mexico state tax return

You must file a New Mexico state return if you are a resident or part-year resident and your income exceeds the filing threshold for your status. A resident is someone who lived in New Mexico for the entire tax year or established a permanent home there. A part-year resident moved into or out of New Mexico during the year. Nonresidents who earned income in New Mexico may also have to file, depending on the amount and type of income.

The filing threshold varies by age and filing status. Generally, if you are under 65 and single, you file if your income is above the standard deduction amount. If you are 65 or older, the threshold is higher. Even if you do not have to file, you may want to if you had taxes withheld from your paychecks, because you could receive a refund.

Deductions and exemptions that lower your New Mexico tax

New Mexico allows a standard deduction that reduces your taxable income. For 2024, the standard deduction for single filers is $6,500 and for married filing jointly is $13,000, though these amounts increase if you are 65 or older. You can also claim a dependent exemption of $4,000 per dependent, which further reduces the income subject to tax.

The state also offers a number of tax credits that directly reduce the tax you owe, such as the earned income tax credit (EITC), the child and dependent care credit, and credits for education expenses. Some credits are refundable, meaning you can receive money back even if you owe no tax. The New Mexico Department of Revenue website lists all available credits and the income limits for each.

Retirement income and pension tax treatment in New Mexico

Distributions from IRAs, 401(k)s, and similar retirement accounts are taxable as ordinary income in New Mexico. However, the state exempts federal pensions, including military retirement pay, from state income tax. State and local government pensions are also exempt if you were a member of the retirement system before a certain date, though the rules vary by system.

Social Security benefits are not taxed by New Mexico. If you receive a pension from a private employer, that income is taxable. Some retirees may benefit from spreading withdrawals across multiple years or timing distributions to stay in a lower tax bracket, but those decisions depend on your specific situation and should be discussed with a tax professional.

How to file your New Mexico state income tax return

You can file your New Mexico return on paper using Form PIT-1, which you mail to the New Mexico Department of Revenue, or you can file electronically through the state's website or through tax software. Electronic filing is faster and reduces errors. The state offers free filing software for residents whose income is below a certain threshold, usually around $79,000.

The federal tax deadline is April 15, and New Mexico follows the same deadline unless it falls on a weekend or holiday. If you need more time, you can request an extension, which gives you until October 15 to file. An extension to file is not an extension to pay, so if you owe tax, you should pay by April 15 to avoid penalties and interest.

What happens if you do not pay New Mexico state income tax

If you owe New Mexico income tax and do not pay by the deadline, the state charges interest and penalties. Interest accrues daily at a rate set by the state, and penalties typically start at 5% of the unpaid tax. If you do not file at all, the penalty is higher. The Department of Revenue can place a lien on your property, garnish your wages, or intercept your federal tax refund to collect the debt.

If you cannot pay the full amount by April 15, you can request a payment plan through the Department of Revenue. The state will work with you to set up monthly payments. Filing on time, even if you cannot pay in full, reduces the penalties you face.

Frequently Asked Questions

Do I have to pay New Mexico income tax if I work remotely for an out-of-state company?

If you are a New Mexico resident and work remotely for a company based elsewhere, you still owe New Mexico income tax on your wages. The location of your employer does not matter; what matters is where you live and where you earned the income. If you are a nonresident who works remotely for a New Mexico company, you may owe New Mexico tax on that income as well.

Can I claim a dependent exemption for an adult child who lives with me?

You can claim a dependent exemption for an adult child only if they meet the IRS definition of a dependent, which includes passing a relationship test, a citizen or resident test, an age test, and a support test. Generally, the person must be under 19 (or under 24 if a full-time student) or permanently disabled. New Mexico follows federal rules for dependent status, so if you can claim the dependent on your federal return, you can claim the exemption on your state return.

What if I moved to New Mexico partway through the year?

You are a part-year resident and must file a New Mexico return for the income you earned while living in the state. You may also owe tax to your previous state on income earned there. Some states have reciprocal agreements that prevent double taxation, but you should check with both states' tax departments to understand your obligations.

Is military retirement pay really exempt from New Mexico income tax?

Yes. Military retirement pay, including pay from the U.S. Army, Navy, Air Force, Marines, Coast Guard, and Space Force, is exempt from New Mexico state income tax. You do not have to report it on your state return. Federal civilian employee pensions are also exempt, but state and local government pensions follow different rules depending on when you joined the system.
