me and a couple buddies are planning to host a car show/ audio competition for autism awareness. all proceeds will be donated to autism research. im not looking for information on how, where, or why to host this event, but i need information on any permits/licenses will be needed to host a non profit event. will this be any different from hosting any other event? or will we need to get extra permits or some kind of paperwork saying the proceeds are going directly to charity. any input is appreciated. thanks!
