Frequently Asked Questions — New Mexico State Taxes
Does New Mexico have a state income tax?
Yes. New Mexico levies a state individual income tax in 2023. The rates and brackets shown above apply to residents filing as single or married filing jointly. Uses federal standard deduction. SS income exempt for most filers.
How do New Mexico tax brackets work?
Like federal taxes, New Mexico uses a marginal (progressive) tax system. Only the income within each bracket is taxed at that rate — not all your income. For example, if New Mexico has a 5% top rate, you pay 5% only on income above the top bracket threshold, not on your entire salary.
What is the difference between marginal and effective tax rate in New Mexico?
Your marginal tax rate is the rate on your highest dollar of income. Your effective tax rate is your total state tax bill divided by your gross income — always lower than your marginal rate. For example, a worker at the top bracket in New Mexico may have a marginal rate of 5.9% but an effective rate several points lower due to income in lower brackets.
When were New Mexico's tax brackets last updated?
