Platte County notes for business owners
Platte County charges 6 percent on sales but only a 1 percent local lodging tax, so lodging totals 12 percent rather than the 13 percent seen in most 6 percent counties. That makes it the only county on the October 2026 chart with a 1 percent county-wide local lodging rate.
An equal 50-50 LLC needs a tie-breaker. Without one, two members with equal votes can deadlock on hiring, borrowing or selling. Wyoming lets the operating agreement set the rule (W.S. 17-29-110): a buy-sell clause, a named third person to break ties, or an agreed outside advisor. Write it before there is a disagreement.
The Platte County Clerk takes mail at P.O. Box 728 in Wheatland, and the county's site is plattecountywyoming.com. Equipment sold to farmers for agricultural use may qualify for exemptions; keep the certificates.
