After the event, sellers should file a special event sales tax return by the 20th of the month following the first day of the special event, if they have not remitted sales tax to the event organizer. For example, if an event was held from February 13-15, the special event sales tax return will be due on or before March 20th. More information about filing a return can be found on the "How to File a Special Event Return" section below.

All sellers participating in the event must collect the applicable state and state-administered local sales taxes due and remit the sales tax collected to the Department. However, sellers may elect to remit such taxes to the event organizer, if the organizer has obtained a special event license. A seller participating in the event may make this election even if the seller has obtained a special event license of their own.

The Annual Flower Trial Garden is a devoted horticultural research garden on the campus of Fort Collins' Colorado State University, open to the public throughout the year near the campus' Center for the Arts. The garden strives to serve as a trial space for the performance of annual plant cultivars in the region's high-altitude Rocky Mountain environmental conditions, with primary annual plantings on display between late May and mid-October. Plant varieties are grouped by genus and arranged by color, with more than 1,000 different cultivars typically on display each year. In addition to the main annual showcase, the garden also presented an annual pansy display, which is planted in fall and on display through the early spring. Perennials cultivated by the garden are also on display year-round across the street from the garden facility.
