Federal Tax Withholding Calculations

Federal income tax withholdings are calculated by:

  1. Multiplying gross pay by the number of pay periods per year to compute your annual salary.
  2. Subtracting the value of allowances allowed (for 2018, this is $4,150 multiplied by the number of withholding allowances claimed).
  3. Determining your annual tax by using the single or married rate tables below.
  4. Dividing the amount of tax by the number of pay periods per year to arrive at the amount of federal withholding tax to be deducted per pay period.
