Employers must withhold a part of the employee’s wages for payment of income tax. New Mexico bases its withholding tax on an estimate of an employee’s State income tax liability. The State credits taxes withheld against the employee’s actual income tax liability on the New Mexico personal income tax return. State withholding tax is like federal withholding tax.
Who Must Withhold
An employer who withholds a portion of an employee’s wages for payment of federal income tax must withhold state income tax. This includes employers of some agricultural workers. There is a limited exception for certain nonresident employees.
Also exempt from withholding tax is income wholly earned by a Native American member of a New Mexico federally recognized Indian nation, tribe or pueblo on the lands of the nation, tribe or pueblo where he or she is enrolled and lives.
The income earned from active-duty military service is also exempt from withholding requirements.
