State of Wyoming

2 stops

  1. Wyoming Business Registration

    Event planning businesses operating in Wyoming must register with the Wyoming Secretary of State if operating as an LLC, corporation, or partnership. Sole proprietors using a trade name must file a DBA registration with the state or county clerk. An LLC provides personal liability protection, which is especially important when coordinating large events.

  2. Wyoming Sales Tax Permit (if applicable)

    Event planning coordination services are generally not subject to sales tax in Wyoming, but if your business sells taxable items — such as event supplies, decorations, floral arrangements, or other tangible goods — you must collect and remit state sales tax. Some states specifically tax event planning or entertainment services. Confirm your obligations with the Wyoming Department of Revenue.

City of Casper / Natrona County

3 stops

  1. Casper Business License (not required for event planning)

    Casper does not require a general business license. The city licenses only specific business types (junk dealers, pawnshops, itinerant merchants, secondhand dealers, hotels/rooming houses, taxicabs); event planning is not one of them, so no city business license is needed. If you work from home coordinating events, confirm home-occupation rules with the city. Events using public spaces need a Special Events Permit (separate requirement).

  2. Casper Special Event Permit (for events in public spaces)

    Events that obstruct public rights-of-way (streets, sidewalks, trails) or occur on outdoor City of Casper property with more than 100 attendees require a Special Event Permit under Municipal Code Chapter 10.72. As the event planner, you may obtain this permit on behalf of your client. Apply through the city's online self-service portal; review can take up to 30 days, so submit as early as possible. Insurance or other conditions may apply depending on the event - see the city's Special Event Guide or call (307) 235-7568.

Confirm requirements for your event with Natrona County Planning at (307) 235-9447 well in advance.
