Crook County notes for business owners
Crook County is one of three counties whose rate changes at the start of 2027. Through December 31, 2026, sales are taxed at 5 percent and lodging at 12 percent. From January 1, 2027, a new 1 percent specific purpose tax takes sales to 6 percent and lodging to 13 percent. A guest ranch that takes deposits now for summer 2027 stays should quote the 2027 rate on those bookings.
A guest ranch mixes taxable lines: the cabin night, meals and possibly guided activities. Set each up separately so the lodging rate only lands on the room portion. Ask the Department of Revenue's taxability desk about guided services before you publish package prices.
The Crook County Clerk takes mail at a post office box in Sundance. If the ranch land is held personally today and you want it in the LLC, the deed is recorded there after formation.
