1. Idaho Secretary of State — Business Registration

   An event planning business structured as an LLC, corporation, or partnership registers with the Idaho Secretary of State through the SOSBiz portal. A sole proprietor trading under a name other than their own legal name files a Certificate of Assumed Business Name instead. Idaho has no county-level DBA filing — assumed business names are registered only with the Secretary of State, whether you are a sole proprietor or an entity trading under a different name. An LLC is worth the modest cost here — coordinating large events means signing venue and vendor contracts in the business's name and carrying real liability exposure.

2. Idaho Seller's Permit (only if you sell taxable goods)

   Idaho taxes tangible personal property and a short list of specifically enumerated services; event planning and coordination labor is not on that list, so your planning fees are not taxable. You do need a seller's permit if you sell taxable items — decorations, favours, floral arrangements, rented or resold supplies — or if you buy goods for resale to clients. Marking goods up and rebilling them to a client is a taxable sale even when the planning fee beside it is not. Registering for a seller's permit through the Tax Commission's Taxpayer Access Point (TAP) is free — there is no application fee. Note the agency is the Idaho State Tax Commission; Idaho has no 'Department of Revenue'.

1. No Nampa General Business License Required

   Nampa does not issue a general business license. Event planning businesses need no city business license unless they operate in one of the specific licensed categories — a Special Event Permit applies only when you coordinate an event using city public property. If you work from home, Nampa's Home Occupation Permit rules may still apply.

2. City of Nampa Special Event Permit

   Events using Nampa public parks, streets, plazas, or other public venues need a Special Event Permit from the City Clerk, routed through Parks & Recreation and other departments for sign-off. As the planner you may be pulling this on the client's behalf. The application covers event details, dates and frequency, expected attendance, a site plan, and proof of general liability insurance. Reserving a specific park or facility is a separate Parks & Recreation booking, and Lloyd's Square carries its own rental fee.

   $50 for one event, $100 for 2–5 events, $150 for 6–10, $200 for 11–15, $250 for 16 or more. Lloyd's Square adds $300 for a half day or $600 for a full day; non-profits get a 30% discount. Park reservations are billed separately.·2–6 weeks; apply at least 30 days ahead for most events and 60 or more days for large events or anything needing street closures.

3. Canyon County Land Use Approval for Events on Unincorporated Land

   Canyon County's Temporary Use permit does not cover events — the checklist limits it to a temporary residence while a dwelling is built, farm worker housing, and occupying an RV outside an RV park for up to 90 days. There is no county special event or public assembly permit. A large outdoor event on private property in unincorporated Canyon County is handled as a land use question through Canyon County Development Services, and where the use is not permitted outright it requires a Conditional Use Permit through a public hearing. Fire, sanitation, and traffic sign-offs are coordinated separately. None of this applies inside Nampa city limits, which uses the city's own Special Event Permit.
