I absolutely hate everything about Colorado sales tax.
You're right, business taxes are more complicated in Colorado (as if they weren't already). I'm with Avalara's social media team in Seattle. As you can imagine, we are getting a lot of calls about this new fee from sellers wondering how tax technology companies will manage it for their customers. Here is a high-level summary of Colorado’s new retail delivery fee that will go into effect on July 1, 2022: Tax rate: $0.27 (adjusted annually for inflation) * Applicable to: delivery of every retail sale of TPP by motor vehicle with at least 1 taxable item Exemptions: follows sale and use product and entity exemptions Registration: set-up delivery fee account Remittance: separate form (DR1786); same filing and payment schedule as SUT; first return and payment: August 20. Who is liable: imposed on the purchaser, but retailers are required to collect and remit Other requirements: - must be displayed on the invoice;- the fee cannot be refunded; - the transaction does not have to originate in CO; - the fee is not subject to sales and use tax I hope this helps.

Sales and Use Tax | City of Boulder
This ordinance was developed by home rule municipal tax professionals, in conjunction with the business community and the Colorado Department of Revenue, as part of a sales tax simplification effort. Economic Nexus requires remote sellers with no physical nexus in Boulder to collect and remit sales tax on retail sales of tangible personal property, commodities, and/or services. Economic nexus levels the playing field between brick-and-mortar retail stores and remote sellers and shifts the responsibility of remitting tax on online sales from the purchasers of goods and services to the retailer.
