Sales Tax 

Colorado retailers that are required to file a sales tax return and remit sales tax on April 20, 2020 may extend their filing and remittance deadline to May 20, 2020.

As such, the Colorado Department of Revenue (CDOR) is providing tax relief in the form of a temporary suspension of the requirements associated with the International Fuel Tax Agreement (IFTA) for any motor vehicle engaged in interstate disaster relief efforts as part of the COVID-19 relief effort until June 30, 2020. This suspension will expedite the process of getting needed relief supplies and fuel into affected areas and immediately reduce the cost and administrative burden of getting these critical supplies across state lines.
