I'm starting a new 5K race. My committee and I want to donate any money we have left over after expenses to a good cause. We'd also like sponsors and other donors to be able to take a tax deduction for their contributions. So I assume we need to be set up as a non-profit organization so that we can do this and that we ourselves are not liable for taxes. I've looked a bit into 501(c)3 organizations, but I've read it can take 4-6 months to go through the process and be quite complicated. How are other races set up if they're not part of an organization that's already a non-profit? Any advice would be greatly appreciated. Thanks!
