Please remember that you must claim the state sales tax refund (TABOR refund) when filing your state income tax return. If you claimed a 2023 refund, the TABOR refund will be combined and issued out with your refund. Unlike the 2022 Colorado cashback, no separate check will be issued.

DENVER, Colo. - January 5, 2022 - The Colorado Department of Revenue (CDOR) understands some taxpayers will be unable to meet Colorado filing and payment deadlines as a result of the recent Marshall Fire. CDOR is offering relief on state-collected taxes to Colorado taxpayers who have been affected by the Marshall Fire. The tax relief measures will mirror IRS measures in the same declared disaster area. 

The Department is offering this relief to any area designated by the Federal Emergency Management Agency (FEMA) as qualifying for individual assistance. The current list of eligible localities is available on the disaster relief page on

Affected taxpayers will be granted a penalty and interest waiver for:

  1. The 2021 4th quarter estimated payment due on January 18, 2022 and the 2022 1st quarter and extension payments due on April 18, 2022. Following the IRS extension, taxpayers will have until May 16, 2022, to make these payments. Colorado offers an automatic extension for filing (October 17); taxpayers do not need to contact the Department if they intend to file by the extension deadline.  
  2. The January 20, 2022 deadline for sales tax (monthly, quarterly, or annual) is extended until May 20, 2022.  For subsequent sales tax deadlines, affected taxpayers are encouraged to either file zero returns, close a location, or to close their accounts through Revenue Online.  Taxpayers are encouraged to use Revenue Online to file sales tax, rather than the Sales and Use Tax System (SUTS), if they plan on asking for a penalty and interest waiver.
  3. Withholding deadlines will be waived for any returns and payments due in January until May 16, 2022..  In addition, annual reconciliations due by January 31 will be extended to March 31.
  4. The Department of Revenue will waive penalty and interest for other taxes and fees on a case by case basis.  Taxpayers are encouraged to contact the Department at 303-238-7378 to discuss their specific needs.

CDOR is not able to automatically apply these tax deadline waivers so affected taxpayers will need to call the tax information hotline at 303-238-SERV (7378) on Monday through Friday from 8 a.m. to 4:30 p.m. to request penalty and interest relief after they receive a bill. CDOR exemptions do not apply to home-rule jurisdictions who collect their own taxes. Please contact them directly to find out if they have also waived any tax deadlines.
