CML Model Ordinance - Economic Nexus & Marketplace Facilitators
In This Section
Background
The CML Model Ordinance on Economic Nexus and Marketplace Facilitators was developed in early 2020 by home rule municipal tax professionals, in conjunction with the business community and the Department of Revenue, as part of a sales tax simplification effort. The Model Ordinance is only for the 68 self collecting home rule municipalities in Colorado.
It has long been recognized, by governments and businesses alike, that various home rule municipalities giving the same term different meanings is a source of complexity in our tax system for businesses that operate in multiple municipalities. Use of “standardized” definitions, such as those put into the Model Ordinance, can help minimize this complexity and provide clarity to those remitting taxes to governments that self collect on the local level in Colorado.
For those municipalities that are not going to be joining the state single point of remittance portal ("SUTS"), we ask that you not adopt the language on economic nexus and continue to move forward with voluntary compliance. The risk of a lawsuit under the United States Commerce Clause if you were to enforce economic nexus without the single point of remittance is high. Using the single point of remittance portal and uniform language will assist in lessening that risk, although not removing it entirely. Please have your attorney review the ordinance as there are certain legal risks, which are touched on in the memo.
If you do adopt the language and/or join with the state single point of remittance, please let us know. We will be keeping track of which municipalities have done what to ease in any confusion.
