A bill to amend chapter 21 of the Internal Revenue Code of 1954 and title II of the Social Security Act to provide that the payment of social security taxes by a nonprofit organization with respect to its employees shall constitute (for both tax and benefit purposes) a constructive filing by such organization of the certificate otherwise required to provide social security coverage for such employees if it has not received a refund or credit of such taxes, and to require the filing of such a certificate by any nonprofit organization which paid such taxes but received a refund or credit because it had not previously filed such certificate.
