Web Fill-in Form Instructions

  • For the form to work correctly, you must use Adobe Reader with javascript enabled. Javascript automatically formats your entered amounts to display with ".00" cents. If this does not occur, your javascript is not enabled.
  • You must complete all four pages of Form D-400 and both pages of  Form D-400TC by using your computer to enter the required information.
  • Do not mix pages from web fill-in forms with pages from other types of forms such as software generated forms, preprinted forms or forms from booklets.
  • Do not handwrite any information.
  • Do not submit photocopies of returns. Submit all pages of original returns only.
  • Do not use brackets for negative numbers on returns. Use a minus sign to show that the amount is negative (Example: -112345.00).
  • Do not select "no graphics" options on your printer.
  • Set Page Scaling to "none". The Auto-Rotate and Center checkbox should be unchecked.
  • Do not use commas when entering amounts.
