From the Payroll Desk
The most common New Mexico payroll mistake is ignoring local minimum wage ordinances. The City of Santa Fe's living wage ($15.40/hr as of March 1, 2026) is higher than the state rate, and Albuquerque requires at least $7.20/hr for tipped employees. If you have employees in those cities, you must pay the local rate where it is higher.
State Unemployment Insurance (SUI)
New Mexico SUI is an employer-paid tax on the first $34,800 of each employee's wages per year. New employers pay the greater of 1.0% or their industry's average rate (1.00% to 1.28% in 2026). Experienced employers are rated up to 5.4% based on their claims history, plus an excess claims premium of up to 1%.
SUI is administered by the New Mexico Department of Workforce Solutions. You must register for an SUI account when you hire your first employee and file quarterly wage reports.
