State of Connecticut

2 stops
  1. Connecticut business registration (Secretary of the State) and trade name filing

    Event planning businesses formed as an LLC, corporation or partnership must register with the Connecticut Secretary of the State; an LLC's certificate of organization costs $120 and the annual report is $80. Sole proprietors and partnerships operating under a trade name file a trade name certificate with the town clerk of the town where the business is located (CGS Sec. 35-1) - Connecticut has no county government and no county clerks, and the Secretary of the State does not file sole proprietor trade names. An LLC also provides personal liability protection that a trade name filing does not.

  2. Connecticut Sales and Use Tax Permit (if selling taxable goods or services)

    Event planning coordination is generally not itself a taxable service in Connecticut, but a planner who sells tangible goods - supplies, decorations, rented items, floral arrangements - or any enumerated taxable service must register with the Department of Revenue Services before making those sales. Registration is done online through myconneCT under 'New Business/Need a CT Registration Number?'. DRS then issues a Sales and Use Tax Permit that must be displayed conspicuously for customers; a separate permit is required for each business location, and a permit issued to a previous owner cannot be reused when a business is purchased.

    $100 registration fee to collect sales and use tax, charged once per location at registrationRegistration through myconneCT is completed online; the Sales and Use Tax Permit follows registration

City of New Haven / New Haven County

3 stops
  1. No general business license required in New Haven

    New Haven does not issue a blanket municipal business license covering every business, and event planners do not need one. City licensing is category specific - food service, peddlers and vendors, and similar regulated activities. Events using public parks, streets or plazas need a separate special event permit, and a trade name certificate ($20) is filed with the City Clerk if you work under a business name.

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

    Events that use New Haven's public parks, streets, plazas or other city venues need a special event or pavilion permit from the city, and as the event planner you may be applying on the client's behalf. Availability is reserved through the parks permit office before the application is filed, and personal checks are not accepted for permit payments.

  3. New Haven Special Event / Temporary Use Permit

    Connecticut has no unincorporated land and no county government, so every event site sits inside a city or town. Events using New Haven parks, streets, plazas or other public property require a special event or pavilion permit from the city (Parks and Public Works, with sign-offs from police, fire and health as the event requires). Expect to provide a site plan, proof of insurance and sanitation arrangements for larger gatherings.
