Quote: There is only one body in the US that regulates nonprofits. That's the IRS.
Wholly untrue.
In NYS until 15 years ago, both the Department of State and the NYS AG's office regulated them in New York. The former dealt with registration and the later with reporting & enforcement. In 1995/6, as a cost saver, etc., that was consolidated to the AG.
"All charitable organizations operating in New York State are required by law to register and file annual financial reports with the Attorney General's Office. This includes any organization that conducts charitable activities, holds property that is used for charitable purposes, or solicits financial or other contributions."
I've worked on cases where people went to jail. In one case, data I was able to retrieve from a seized PC cost a lawyer his freedom and his profession [convicted felons can't practice law].
For example, he tried to hide purchases he made with trust funds for collectable wines he got from a Florida PBS auction as "investments" for the trust. The WordPerfect print-out entitled "My Wine Collection" from his personal PC made his lawyer's contention look silly.
