New Mexico's income tax moved in 2025, so any register built on the old schedule withholds the wrong amount. House Bill 252, effective 1 January 2025, lowered the bottom rate and added a new middle band. The 2026 schedule, set by the New Mexico Taxation and Revenue Department, runs from 1.5% on the first $5,500 of taxable income up to 5.9% on single-filer income over $210,000.
On the employer side, New Mexico unemployment insurance runs on a $34,800 wage base at a 1.00% new-employer rate. The state minimum wage is $12 an hour and the Healthy Workplaces Act mandates paid sick leave from your first hire.
Does New Mexico have a state income tax in 2026?
Yes. New Mexico has a graduated personal income tax with six brackets for 2026, running from 1.5% on the first $5,500 of taxable income up to a top rate of 5.9% on single-filer income over $210,000. All six rates are set by the New Mexico Taxation and Revenue Department.
House Bill 252 restructured these brackets from 1 January 2025. It lowered the bottom rate to 1.5% and added a new 4.3% band, so a register built on the old schedule withholds the wrong amount from every pay cycle.
The single-filer bands stack like this for 2026: 1.5% up to $5,500, then 3.2% to $16,500, 4.3% to $33,500, 4.7% to $66,500, 4.9% to $210,000, and 5.9% above that. Each rate applies only to income inside its band, so an employee never pays the top rate on their whole salary.
Married-filing-jointly and head-of-household employees hit the 5.9% rate later, at $315,000 rather than $210,000. The HB252 restructure was the first major bracket change since 2005. For the minimum wage and overtime rules that sit alongside these withholding obligations, the weekly wage floor is a separate compliance question. Confirm your withholding tables carry the post-2025 schedule before you run a single pay cycle here, and compare how New Mexico stacks up against neighbouring Texas state income tax, which has no personal income tax at all.
How does New Mexico income tax withholding work for employers?
You withhold New Mexico income tax from every employee's pay and remit it to the Taxation and Revenue Department. New Mexico uses the federal Form W-4, so there is no separate state withholding certificate for most employees.
Withholding tracks the same graduated 1.5% to 5.9% schedule, applied through the department's percentage-method tables in publication FYI-104.
Register with the Taxation and Revenue Department for a Combined Reporting System (CRS) identification number before your first payday. You file and pay withholding on the CRS return, monthly or quarterly depending on the size of your liability, and reconcile annually. The cadence is what catches new employers out, not the rate itself.
Because New Mexico leans on the federal W-4, the onboarding paperwork stays light: one federal form drives both federal and state withholding. The work sits in the back end, getting the right post-HB252 percentage tables loaded and filing the CRS return on time, every period, even in a month when a deposit happens to be small. See how this compares with Colorado state income tax withholding, which runs a flat 4.4% rate.
What is New Mexico's unemployment insurance wage base and rate for 2026?
New Mexico's UI taxable wage base is $34,800 per employee for 2026, up from $33,200 in 2025. New employers pay a rate of 1.00%, or the industry average where that is higher.
Experience-rated employers pay between 0.33% and 5.40%, set by their own layoff history and administered by the New Mexico Department of Workforce Solutions.
Hire your first New Mexico employee and you owe UI on the first $34,800 of that person's annual wages at 1.00%. Once you have enough claims history the rate floats between 0.33% and 5.40%. File and pay quarterly.

You pay UI on the first $34,800 of each employee's annual wages; everything above that in the calendar year is not taxed. A new employer holds the 1.00% rate until it builds enough history to be experience-rated, after which the rate floats with its own claims. Track your termination decisions carefully, since every claim affects next year's rate.
The federal layer sits on top. FUTA is 6.0 percent on the first $7,000 of wages, less the full credit for compliant state payers, which leaves an effective 0.6%. Pay New Mexico UI correctly and on time and you keep that credit; miss it and FUTA can climb. Use the employer cost calculator to see exactly what UI and federal payroll taxes add to your New Mexico headcount cost.
What other payroll rules apply to New Mexico employees?
You run the full federal stack: Social Security at 6.2% to $184,500, Medicare at 1.45%, and FUTA at 0.6% on the first $7,000. New Mexico's minimum wage is $12 an hour, with a $3 cash wage for tipped staff.
New Mexico has no state paid-family-leave programme, so federal FMLA is the only job-protected family leave. It does mandate paid sick leave under the Healthy Workplaces Act, detailed on the New Mexico leave page.
The Healthy Workplaces Act is the rule out-of-state employers miss. Every private employer, from the first employee, must let staff accrue paid sick leave at one hour for every 30 hours worked, usable up to 64 hours a year. You can frontload the 64 hours on 1 January instead of accruing, but you cannot skip it, and you must keep accrual records for four years. See the paid leave page for the full accrual rules.
On wages, the $12 state floor is the baseline, not always the number you pay: Santa Fe and Las Cruces set higher local minimums, while Albuquerque tracks the state rate. There is no state disability insurance and no state paid family leave, so for job-protected family leave you are on federal FMLA at 50 employees. See the full United States hiring guide for how the federal stack applies across all 50 states; what changes is the state layer on top.
How Teamed runs New Mexico payroll end to end
Teamed becomes your legal employer of record in New Mexico for $599 per employee per month flat. Zero FX mark-up. Statutory employer cost passes through at cost, itemised on every invoice. No setup fee, no exit fee.
You hire the person. Teamed registers with the Taxation and Revenue Department and Workforce Solutions, runs the graduated withholding, files UI quarterly, and tracks Healthy Workplaces Act accrual. Everything runs on one platform.
Real HR and legal experts handle your New Mexico hires and know the post-HB252 1.5% to 5.9% schedule, the $34,800 UI wage base, and the one-hour-per-30 sick-leave rule by heart. An actual person, not a chatbot or a pooled queue. You see every cost: state withholding, UI contributions, and federal employer taxes pass through at cost, itemised and auditable on every invoice.
Contractor onboarding, EOR payroll, and entity graduation all live on one platform: a New Mexico contractor who converts to W-2 keeps their record, and that same employee can graduate to your own US entity without switching systems. Use the Crossover Calculator to see the month the cost case for your own entity overtakes the EOR fee, or the employer cost calculator to see what New Mexico headcount actually costs. EOR is the right model for New Mexico, until it isn't.
The thing we flag first on New Mexico is the 2025 bracket restructure. Plenty of payroll setups still carry the old schedule and the old bottom rate, so the withholding is quietly wrong. Get the post-HB252 tables in, run the Healthy Workplaces accrual from day one, and the rest is just filing the CRS return on time.
New Mexico moved its income tax in 2025. The brackets people quote are often the old ones.
Get that wrong and you withhold the wrong amount from every cheque, on a graduated scale that now tops out at 5.9% over $210,000.
Right tables, right UI base, sick leave from day one. That is the part we run for you.
