Effective December 1, 2018, the Colorado Department of Revenue will require out-of-state retailers who do business and have substantial nexus in Colorado to register to collect and remit retailer’s use tax. This policy change is in reaction to the South Dakota v. Wayfair decision. The state did not pass enabling legislation. The Department plans to provide guidance for out-of-state retailers by administrative rule. The Department is soliciting feedback on the emergency rules. The rule will be consistent with the Supreme Court’s decision in Wayfair, including prospective application and a small-seller exception for retailers. An out-of-state retailer must apply for a Colorado Sales Tax License and if they don’t have a location in Colorado they will collect Colorado retailer’s use tax if, in either the previous or current calendar year the retailer has:
The Colorado retailer’s use tax does not apply to county or city taxes that are administered by the state. Remote sellers will be responsible for collecting the state tax plus the RTD/CD/RTA taxes. This legislation only applies to state administered taxes. If any home rule city imposes similar legislation it would be in violation of the dicta in the South Dakota v Wayfair case.
Beginning November 1, 2018, out-of-state retailers can register for a Colorado sales tax license. Out-of-state retailers who exceed the economic nexus threshold have a registration deadline of November 30, 2018. Because the rule will not be applied retroactively, out-of-state retailers are not required to collect sales tax on sales that occurred prior to the registration deadline. For more information, you can read the Department’s news release or their FAQ page.

UPDATE: The Colorado Department of Revenue has implemented a grace period for remote sellers to ensure that retailers have sufficient time to make required systems changes to comply with Colorado’s post-Wayfair sales tax collection requirements. The grace period will run through May 31, 2019 and will apply the new economic nexus laws and destination sourcing changes. Starting June 1, 2019, sellers will need to follow the new sales and use tax rules. However, it is important to note that if a retailer does not collect sales tax during the grace period, they must still comply with Colorado’s reporting statute. The reporting requirements statute, which requires non-collecting retailers to provide notices to Colorado customers and the Department about purchases where the retailer didn’t collect tax, will be strictly enforced during the grace period.
