Sales Tax Deadlines

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. This is a one-time extension of the April 20, 2020 filing and remittance deadline for state and state-administered sales taxes. The extension does not apply to self-collecting home-rule jurisdictions. The Deparment will waive penalties and interest that may accrue retailers that file their return and remit the full amount of state and state-administered sales tax due April 20, 2020 on or before May 20, 2020.

Temporary Suspension of IFTA Requirements

On March 10, 2020, Governor Jared Polis declared a State of Emergency for the state of Colorado.

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.
