New Mexico does have a state income tax
New Mexico taxes the income of residents and non-residents who earn money within the state. The state income tax rate ranges from 1.7% to 5.9% depending on your income level, and it applies to wages, self-employment income, investment income, and other sources. Unlike some states that have no income tax at all, New Mexico funds state services through this tax.
If you live in New Mexico or work there, you will owe state income tax on your earnings. The tax is progressive, meaning higher earners pay a higher percentage. You file New Mexico state taxes separately from your federal return, usually on Form PIT (Personal Income Tax Return).

Who must file a New Mexico state income tax return
You must file if you are a New Mexico resident with income above the filing threshold. For the 2023 tax year, that threshold depends on your filing status and age. A single person under 65 must file if they had gross income of $12,200 or more; a married couple filing jointly must file if their combined income was $24,400 or more. These thresholds change each year, so check the current year's instructions on the New Mexico Department of Revenue website.
Non-residents who earned income within New Mexico must also file a state return, even if they do not live there. This includes people who worked in New Mexico for part of the year or received income from New Mexico sources like rental property or business operations. Part-year residents—people who moved to or from New Mexico during the tax year—file a return showing income for the months they lived in the state.
You may need to file even if your income is below the threshold if you had taxes withheld from your paychecks or if you owe self-employment tax. Filing allows you to claim a refund of any overpaid tax.
New Mexico income tax brackets and rates
New Mexico uses a progressive tax system with five tax brackets. The lowest rate is 1.7% on income up to a certain amount, and the rate increases as your income rises, reaching 5.9% on the highest bracket. The exact dollar amounts for each bracket change annually to account for inflation.
For example, a single filer in 2023 paid 1.7% on income up to $5,900, then 3.2% on income between $5,900 and $11,800, and so on, with the top rate of 5.9% explore to income over $210,000. Married couples filing jointly have higher bracket thresholds. The state publishes updated brackets each year, so your actual tax depends on the year you are filing for.
The progressive system means you do not pay the top rate on all your income—only on the portion that falls into the highest bracket you reach. This is different from a flat tax, where everyone pays the same percentage regardless of income level.
Deductions and credits that lower your New Mexico tax
New Mexico allows you to deduct federal income taxes you paid during the year. This is one of the largest deductions available and can significantly reduce your state taxable income. You claim this deduction on your state return, not on your federal return.
The state also offers a dependent exemption credit. You can claim a credit for each dependent, which reduces your tax liability dollar-for-dollar. The amount varies by dependent and changes annually. Additionally, New Mexico has credits for education expenses, including contributions to a 529 college savings plan, which may lower your state tax.
Other credits may be available depending on your situation, such as credits for property taxes paid or for certain types of income. The New Mexico Department of Revenue publishes a full list of available credits with each year's tax forms and instructions.
How to file your New Mexico state income tax return
You file your New Mexico return after you complete your federal return, since your federal tax information carries over to the state form. New Mexico accepts returns filed by mail or electronically through approved tax software or a tax professional. The state does not operate its own e-file system; you must use IRS-approved software or a preparer.
The main form is the PIT (Personal Income Tax Return), which asks for your income, deductions, credits, and filing status. You attach schedules for different income types—for example, Schedule C if you are self-employed, or Schedule NEC if you received non-employee compensation. The instructions that come with the form walk through each line.
You can file electronically starting in late January each year. The important date is April 15, the same as the federal important date. If you need more time, you can request an extension, which gives you until October 15 to file. An extension to file does not extend the important date to pay; if you owe tax, you should pay by April 15 to avoid penalties and interest.
Payment options and what happens if you do not file
If you owe New Mexico state income tax, you can pay by check, money order, electronic funds withdrawal, or credit card. Payments by check or money order go to the address listed on the tax form instructions. Electronic payments are processed through the state's online system or through approved payment processors.
If you do not file a required return, the state may assess a penalty. The penalty is typically a percentage of the unpaid tax, and interest accrues on any tax owed. The longer you wait, the larger the penalty and interest become. If you owe back taxes, filing as soon as possible and paying what you can reduces the total amount owed over time.
If you filed but underpaid your tax, the state will send you a bill. You can pay in full or, in some cases, request a payment plan. Contact the New Mexico Department of Revenue if you receive a bill and cannot pay when ready.
Frequently Asked Questions
Does New Mexico tax retirement income or Social Security?
New Mexico does not tax Social Security benefits. Retirement income from pensions and 401(k) withdrawals is taxable, though the state offers a pension income deduction for certain types of retirement income. The rules vary by the source of the retirement funds, so check the current year's instructions or contact the Department of Revenue for your specific situation.
What if I moved to New Mexico partway through the year?
You file as a part-year resident and report only the income you earned while living in New Mexico. You also report income from New Mexico sources earned before you moved there. Your tax brackets and deductions are prorated based on the number of months you were a resident. The state form includes a schedule to calculate this.
Can I file my New Mexico return without filing a federal return?
You can file a state return without filing a federal return, though many people file both. If you had taxes withheld from your paychecks, filing a state return may result in a refund even if you do not owe federal tax. However, some state credits require you to have filed a federal return to claim them.
What if I worked in New Mexico but live in another state?
You must file a New Mexico non-resident return for the income you earned in the state. You may also owe tax to your home state on the same income. Some states have reciprocal agreements to avoid double taxation, but you should file in both states and check whether you may have access to for a credit on one return for taxes paid to the other.
Where do I send my New Mexico tax return?
Mail paper returns to the address shown in the current year's form instructions, which is typically the New Mexico Department of Revenue in Santa Fe. If you file electronically, the software or preparer submits it directly to the state. Keep a copy of your return and proof of mailing or electronic filing for your records.
