### Withholding Formula (Effective Pay Period 07, 2024)

- Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
- Subtract the nontaxable biweekly Federal Employees Health Benefits Plan payment(s) (includes dental and vision insurance program and Flexible Spending Account — health care and dependent care deductions) from the amount computed in step 1.
- Add the taxable biweekly fringe benefits (e.g., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
- Multiply the adjusted gross biweekly wages by the number of pay dates in the tax year to obtain the gross annual wages.
- If the employee has submitted a 2020 or later Federal Form W-4, then subtract the annual deductions claimed in step 4b of the Federal Form W-4.

Note: If the result is less than zero, the Adjusted Annual Wage Amount is zero.

- Apply the taxable income computed in step 4, or if applicable, in step 5, to the following tables to determine the annual New Mexico tax withholding:
