Form W-4 Calculator

  The app uses the requested fields, the worksheets and tables from  Form W-4 for 2020.  It combines those with the Employer's Withholding Worksheet from Publication 15  to display the expected FIT withholding.

   The calculator displays a screen for entering the information on each of the four steps of the Form W-4.  Where needed, the screen shows any additional worksheet fields and does the calculations needed.  The expected FIT withholding is continuously shown at the botton of the window.
   At any time the W-4 info button displays the entries for the Form W-4.  The Worksheet button shows, in a scrollable window, the resulting Employer's Withholding Worksheet values.  The final value on the worksheet is the FIT withholding shown at the bottom of the screen.
   After installing, no connection to the Internet is needed.  No information is downloaded, uploaded or saved when the calculator is exited.
