Does the constitutional guarantee against compulsory self-disclosure apply to non-profit organizations?

"... the constitutional guarantee against compulsory self-disclosure concerned primarily with protection of individual civil liberties, is not to be interpreted to insulate economic or other interests of organizations, incorporated and unincorporated, when to do so would be to frustrate appropriate governmental regulation. (United States v. White, 322 U.S. 694, 700, 64 S.Ct. 1248, 1251, 88 L.Ed. 1542.)"

The courts have long recognized that the state may require a physician to report deaths and their causes; and may require a druggist to report the sale of poison even though "compliance with one of these statutory regulations may ... prove an important factor in leading to his detection." These obvious possible self-incriminatory requirements are "not sufficient to render the legislation invalid". People v. Rosenheimer, 209 N.Y. 115, 120, 102 N.E. 530 (1913).
