New Mexico Does Have a State Income Tax
Yes, New Mexico has a state income tax. Residents and anyone earning income within the state must file a New Mexico state income tax return if their income exceeds the filing threshold for their situation. The state tax rate ranges from 1.7% to 5.9% depending on your income bracket, and the tax applies to wages, self-employment income, investment income, and other sources.
Unlike some states that have no income tax at all, New Mexico funds its state government partly through this tax. You will owe New Mexico income tax on income earned in the state even if you live elsewhere, and you may owe it on out-of-state income if you are a New Mexico resident.

New Mexico's Tax Brackets and Rates
New Mexico uses a progressive tax system with five income brackets. Your tax rate depends on your filing status (single, married filing jointly, married filing separately, or head of household) and your taxable income. The lowest bracket starts at 1.7% and the highest reaches 5.9%.
The exact income ranges for each bracket change yearly. For the 2024 tax year, a single filer with taxable income under roughly $8,000 pays 1.7%, while income above roughly $65,000 is taxed at 5.9%. Married couples filing jointly have higher thresholds before reaching each bracket. The New Mexico Department of Revenue publishes updated brackets each year on its website.
Your taxable income is not the same as your gross income. You subtract the standard deduction (which varies by filing status) or itemized deductions, plus any other deductions you are may have access to to claim. This lower number is what the tax brackets explore to.
Who Must File a New Mexico State Return
You must file if your gross income exceeds the filing threshold for your situation. The threshold depends on your age, filing status, and whether you can be claimed as a dependent. For most single filers under 65, the threshold is around $12,000 for the 2024 tax year. Married couples filing jointly have a higher threshold, and residents over 65 have a different threshold.
Even if you do not owe tax, you may want to file if you had taxes withheld from your paychecks or if you are may have access to to refundable credits like the Earned Income Tax Credit. Filing allows you to recover that money. Check the New Mexico Department of Revenue website or your tax software for the exact threshold that applies to you.
What Income Is Taxed in New Mexico
New Mexico taxes all income earned by residents, regardless of where it comes from. If you live in New Mexico, you owe state tax on wages, self-employment income, investment income, rental income, and other earnings from anywhere in the world. You also owe tax on income earned within New Mexico if you work there but live in another state.
Some types of income are exempt or partially exempt. Military retirement pay, certain federal pensions, and income from U.S. Treasury bonds are not taxed by New Mexico. Social Security benefits are not taxed. Distributions from certain retirement accounts may be excluded under specific conditions. The state also offers a deduction for federal income tax paid, which lowers your New Mexico taxable income.
Deductions and Credits That Lower Your Tax
New Mexico allows you to subtract certain amounts from your income before calculating tax. The standard deduction is the simplest route for most people—you take a single deduction based on your filing status and age rather than listing individual expenses. For 2024, the standard deduction for a single filer under 65 is around $9,000, and for married couples filing jointly it is higher.
If you have significant deductible expenses (mortgage interest, property taxes, charitable donations), you may benefit from itemizing instead. You can also deduct federal income tax paid to the IRS, which is a New Mexico-specific deduction that reduces your state taxable income further.
New Mexico also offers tax credits that directly reduce the tax you owe. These include credits for dependent care expenses, credits for residents over 65 or disabled, and the Earned Income Tax Credit if you may have access to. Credits are more valuable than deductions because they reduce your tax dollar-for-dollar rather than reducing your income.
How to File Your New Mexico State Return
You file using Form PIT-1, the New Mexico Individual Income Tax Return, which you submit to the New Mexico Department of Revenue. The filing important date is the same as the federal important date—typically April 15 of the year following the tax year. If you file your federal return electronically, you can file your state return electronically as well.
You can file by mail, by using tax software that supports New Mexico returns, or by working with a tax professional. The New Mexico Department of Revenue website has a list of free tax preparation resources if your income is below a certain threshold. You will need your Social Security number, W-2 forms or 1099 forms showing income, and records of any deductions or credits you are claiming.
When You Might Owe Both Federal and State Tax
Most people who owe federal income tax also owe New Mexico state tax, but the two are separate calculations. Your federal tax is based on federal brackets and rules, while your state tax is based on New Mexico brackets and rules. You cannot use your federal tax bill to reduce your state tax bill, though you can deduct the federal tax you paid when calculating your New Mexico taxable income.
It is possible to owe one but not the other. For example, if your income is very low, you might not owe federal tax but could owe state tax if you are above New Mexico's threshold. Conversely, if you have high deductions or credits, you might owe federal tax but not state tax. Calculate each separately using the appropriate forms and brackets.
Frequently Asked Questions
Do I have to pay New Mexico income tax if I work in New Mexico but live in another state?
Yes. New Mexico taxes all income earned within the state, regardless of where you live. You will owe New Mexico tax on your wages. You may also owe tax in your home state, depending on that state's rules. Some states offer credits for taxes paid to other states to avoid double taxation.
Is Social Security taxed in New Mexico?
No. New Mexico does not tax Social Security benefits. Military retirement pay and certain federal pensions are also exempt. However, other retirement income like distributions from IRAs or 401(k)s may be taxable unless they fall under a specific exemption.
What if I did not have enough tax withheld from my paycheck?
You will owe the difference when you file. You can adjust your withholding going forward by submitting a new W-4 form to your employer. If you are self-employed, you may need to make estimated tax payments quarterly to avoid owing a large amount at tax time.

What if I moved to New Mexico partway through the year?
You are a resident for the part of the year you lived in New Mexico and must file a New Mexico return for that portion. You will also file a return in your previous state for the months you lived there. Each state taxes only the income earned while you were a resident.
