Colorado DOR to Paper Filers: Beware!


 ... of outdated forms and blue ink.

In keeping with the season, the Colorado Department of Revenue has issued a somewhat scary warning to business taxpayers who still file Colorado tax returns on paper:  Beware.

The warning should be heeded. It reads (in bold):

“Starting now, if you continue to use outdated Colorado business tax forms, the Department of Revenue will not process these forms, which may result in a  late filing penalty and loss of the vendor/service fee (timely filing discount).”

Not only must the latest version be used, it must be completed in black ink. The department is switching over to a new imaging system and other ink colors aren’t recognized.

If this sends chills up your spine, it should.

Correct forms are:

  • Mailed to you by the department, for the specific filing period. OR
  • Downloaded at the time you file a return from www.TaxColorado.com. Do not modify downloaded forms in any way.
  • Are 8 ½ x 11 and have a barcode that automates and facilitates processing.

Incorrect forms are:

  • In the “old coupon booklet” (disallowed since January 1, 2014).
  • Old forms copied and whited out.
  • Photocopied forms and faxed forms.
