Withholding Formula (Effective Pay Period 03, 2025)

  1. Subtract the nontaxable biweekly Thrift Savings Plan contribution from the gross biweekly wages.
  2. 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.
  3. 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.
  4. Multiply the adjusted gross biweekly wages by the number of pay dates in the tax year to obtain the gross annual wages.
  5. Determine if the employee's gross salary and wages are less than or equal to the amount shown in the Low Income Exemption Table below. If so, no income tax is to be withheld.

1 Number of regular allowances claimed on DE-4.

Note: If the employee uses additional allowances for estimated deductions to reduce the amount of salaries and wages subject to withholding, such allowances must not be used in the computation of the low income exemption (Step 5) or standard deduction (Step 7).

  1. Determine the additional withholding allowance for itemized deductions (AWAID) by applying the following guideline and subtract this amount from the gross annual wages:

AWAID = $1,000 x Number of Itemized Allowances Claimed for Itemized Deductions on 
DE-4 or W-4.

  1. Subtract the standard deduction shown in the Standard Deduction Table below from the result of step 6 to determine the taxable income.

must not be included when determining the tax credit.
