Withholding Formula (Effective Pay Period 02, 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 annual wages.1
1 If gross annualized wages are less than $5,000, taxes will not be withheld.  Determine the standard deduction by applying the following guideline and subtract this amount from the gross annualized wages computed in step 4:
Standard Deduction2 = 15 percent x Annualized Wages
2 Minimum of $1,800/Maximum of $2,700  Determine the dependent allowance by applying the following guideline and subtract this amount from the result of step 5 to determine the taxable income:
