We are a 501(c)(3) nonprofit research organization. A 501(c)(6) business membership association is starting to show strong support for us, as our research is valuable to them. Can the (c)(6) trade association ask its national membership to support us (either directly, or by collecting donations from members and then sending us one large donation check)?
What charitable solicitation registration requirements would be in play? We know that most "member" organizations are exempt from registrations, but if they are soliciting on behalf of our 501(c)(3), the waters seem to get muddy. Help!
