New Mexico state income tax withholding

State unemployment insurance (SUTA)
Every New Mexico employer pays state unemployment tax. Rates are experience-rated — new employers start at a standard rate, then rates adjust based on how often former employees claim benefits.
Check your specific rate letter from the Department of Workforce Solutions.
New-hire reporting
Federal law requires reporting every new hire to the state within 20 days. New Mexico uses the same form/portal for both federal and state reporting.
Filing frequency
Federal (IRS Form 941): quarterly for most employers. Deposits monthly or semi-weekly based on liability.
New Mexico withholding: frequency varies based on liability — most small employers file quarterly.
