Summary
Thornton levies a 7% excise tax on the price paid for hotel rooms, guesthouses, mobile homes, autocamps and other public accommodations rented to guests, collected in lieu of the city's general sales tax. Marketplace facilitators listing rentals, including short-term rental platforms, are treated as vendors responsible for the tax under City Code Section 26-466.
There is levied an excise tax on the price paid or charged for the lease, rental or furnishing of rooms or other public accommodations to any person who, for a consideration, uses, possesses or has the right to use or possess any room or other public accommodations in any hotel, apartment hotel, guesthouse, guest ranch, mobile home, autocamp, trailer court or park or any other place furnishing rooms or other public accommodations... Such tax on public accommodations shall be subject to the following conditions: (1) The tax levied shall be in lieu of city sales tax on such rental or furnishing of public accommodations. (2) The tax levied shall be collected and paid at the rate of seven percent of the purchase price. (3) The purchase price paid or charged for such accommodations shall exclude the sale of any goods, services and commodities other than the furnishing of rooms or other accommodations. (4) Any person or marketplace facilitator offering or facilitating the sale, lease or rental of such rooms or other public accommodations available shall, for all purposes of this article, be deemed to be a retailer or vendor as defined in Section 26-388.

Full Breakdown
Thornton imposes an excise tax under Chapter 26, Article VII of the City Code on anyone who rents or is furnished a room or other public accommodation in the city for consideration. Section 26-466 sets the rate at seven percent of the purchase price and applies it "in lieu of city sales tax" so guests are not charged both taxes on the same room charge. " Ordinance No. 3644, adopted February 28, 2023, added subsection (4), which folds short-term rental platforms into the tax by declaring any "marketplace facilitator" that offers or facilitates the lease or rental of taxable rooms a retailer or vendor under Section 26-388, so Airbnb-style hosts and booking platforms must collect and remit the seven percent charge the same as a traditional hotel.
The taxable purchase price excludes any goods, services, or commodities sold apart from the room itself, such as restaurant meals or parking. Section 26-467 carves out an exemption for permanent residents: a guest who signs a written agreement, before occupancy begins, for at least 30 consecutive days during the calendar or preceding year pays no lodgings tax on the room charge, though the exemption does not extend to other goods or services sold to that resident unless separately exempt. Operators who collect the tax must remit it under the estimated-tax and collection procedures of Section 26-393.
Violations & Fines
Operators who fail to pay the lodgings tax owe the full amount plus a ten percent penalty and interest computed under Section 26-393, and the unpaid balance becomes a debt collectible by the city under Section 26-468. Any violation of Article VII is punishable under Section 1-8(a) as a municipal offense, but Section 26-469 bars incarceration for anyone under 18 unless ordered for contempt or failure to obey a court order.
