New Mexico State Tax Updates:  Any changes to Exempt status, Filing Status or Deductions amount (4b) on your Federal Form W-4 are also applied to your State of New Mexico withholding.  Should you require an additional amount of withholding, a different Deductions amount (4b), or wish to claim Exempt for the State of New Mexico Income Tax, print the form at University of New Mexico Payroll Department State Withholding form and deliver it to the Payroll Office directly, as Payroll personnel must update it.

New Employees:  Your W-4 is defaulted to Single.  You may update your W-4 after your start date.
