Unemployment tax

Typically companies in New Mexico become eligible to receive an Unemployment Employer Account Number (EAN) once they have paid $450 of wages in a calendar quarter OR employ at least one person in any part of the week for 20 weeks within a calendar year.

Once you are eligible, you may register with the New Mexico Department of Workforce Solutions online. You should receive your Employer Account Number and tax rate instantly after registering. For new employers the rate is typically 1%, but may vary depending on the industry. You can also call the agency at (877) 664-6984 to inquire about your account number and rate.

Workers' Compensation Assessment Fee

The New Mexico Workers’ Compensation Act supports the regulation of Workers’ Compensation Assessment Fee in New Mexico. It is separate from your Workers’ Compensation insurance policy. Currently, employers with 3 or more active employees (even if only one employee is working in New Mexico, and even if some of your workers are contractors and/or temporary workers) are required to be covered and pay the Workers’ Compensation Assessment Fee. The fee is calculated based on the number of covered workers at the end of each quarter. Find out more info about required coverage from the New Mexico Workers’ Compensation Administration site.

To have Gusto pay your New Mexico Workers' Assessment Fee, update your "New Mexico Workers Comp. Act Coverage" to "Covered" in Gusto:

  1. Click Company Details.
  2. Scroll to the headline "New Mexico Tax Setup."
  3. Click Manage Taxes.
  4. Scroll to "State Tax Settings."
  5. Click edit next to "Worker's Comp. Act Coverage."
  6. Select Covered for the New Mexico Workers Comp. Act Coverage.

Troubleshooting TPA for unemployment tax

  • Selecting effective dates
    •  The "begin date" needs to be the beginning of the quarter MM/YY (Q1 = 01/01, Q2 = 04/01, Q3 = 07/01 and Q4 = 10/01) or Gusto may not be able to file or make tax payments.
    • The TPA "end date" should be left blank.
  • Prior payroll service provider
    • If you're switching from another provider, you must un-assign roles from your previous provider and assign roles to Gusto.
    • The TPA end date for your prior payroll service provider should be updated to show the end date for the quarter they last filed for you (Q1 = 03/31, Q2 = 06/30, Q3 = 09/30 and Q4 = 12/31).
      • The previous TPA access and roles will need an end date, before roles can be assigned to Gusto.
  • Multiple locations
    • If your company has more than one reporting unit/location, please be sure that Gusto has TPA roles for each unit. By default, the agency's system assigns Gusto TPA roles to all reporting units.

If you have any questions in regards to assigning Gusto's roles to your account, please contact NMDWS at (877) 664-6984.
