As clubs review dues for members, include the Rotary required items plus the Club costs supported with member assessment.
Rotary International bills semi-annually for dues, magazine, insurance and council on legislation.
Clubs may assess the members for club costs and should clearly disclose that information. Click here for a sample analysis.
Clubs may include optional items with dues billings. Often we see:
  • Club Foundation Donation
  • The Rotary Foundation Donation (can be added as an option but cannot be part of the regular, mandatory dues payments)
From The Rotary Code of Policies:
5.020.2. Prohibition of Mandatory Contributions to The Rotary Foundation 
The Rotary Foundation has developed on the basis of voluntary contributions. Contributions to the Foundation shall not be a condition of membership, and any reference implying such condition of membership shall not appear on the membership application card. Clubs are prohibited from enacting a bylaw that makes contributions to the Foundation a condition of membership. Any reference to such contributions on membership identification cards is not authorized. (November 2004 Mtg., Bd. Dec. 59)
