Special Considerations

State W-4 Form

New Mexico accepts the federal Form W-4 for withholding purposes. Employees may use New Mexico Form RPD-41359 to claim different allowances or additional withholding for state purposes.

Electronic Filing Mandate (NEW for 2026)

Effective January 1, 2026: New Mexico requires electronic filing and payment for most employers.

Who must file electronically:

  • All employers with 25 or more employees
  • Employers with annual withholding of $25,000 or more

Electronic options:

  • New Mexico Taxpayer Access Point (TAP)
  • Approved third-party payroll providers
  • EFT payment

Withholding Tables

New Mexico Taxation and Revenue Department publishes annual withholding tables. The FYI-104 publication contains percentage method formulas and wage bracket tables.

No Local Income Taxes

New Mexico does not permit local income taxes. Only state withholding is required.

Gross Receipts Tax

New Mexico imposes a Gross Receipts Tax (GRT) on businesses, but this is not a payroll withholding tax. It functions similarly to a sales tax and is not withheld from employee wages.

Reciprocal Agreements

New Mexico has no reciprocal agreements with other states. All wages earned in New Mexico are subject to withholding regardless of the employee's state of residence.
