Please Note: For all Personal Income and Business Tax Forms printed in 2008 and every year after, Delaware now requires a 1d barcode to be placed on the form. All forms on this page contain a 1d barcode in their design, except where noted. If there is not a barcode in the design, you do not need to add a barcode to the form. If there is a barcode in the design, the barcode is mandatory if you plan to add that form to your software package. Each barcode is different, depending on the software company producing the form, the form type and the form's page number. To create your barcodes, use the 1d Barcode Generator.

Forms with an asterisk (*) do not contain a barcode.
