Seeking legislation germane to the organization's programs is a permissible means of attaining social welfare purposes. Thus, a section 501(c)(4) social welfare organization may further its exempt purposes through lobbying as its sole or primary activity without jeopardizing its exempt status. An organization that has lost its section 501(c)(3) status due to substantial attempts to influence legislation may not thereafter qualify as a section 501(c)(4) organization. In addition, a section 501(c)(4) organization that engages in lobbying may be required to either provide notice to its members regarding the percentage of dues paid that are applicable to lobbying activities or pay a proxy tax .
