I am considering membership in a 501(d) organization. Is there a way to continue to make contributions to Social Security for a 501(d) member?

“ Is there a way to continue to make contributions to Social Security for a 501(d) member?”---->I don’t think so; 501(d) organizations can have employees. Such individuals are non-members of the organization, and would receive Forms W-2. Members of the organization do not meet the tests and requirements to be treated as employees.
