It is possible to report fraud anonymously, including home-based business tax scams, abuses in tax shelters, retirement plans, and other tax avoidance transactions. The Internal Revenue Service offers hotlines and forms for people to report suspected business and tax fraud. The Social Security Administration also accepts anonymous alleged fraud reports.
The IRS Office of Tax Shelter Analysis is primarily interested in information about transactions that could create compliance risks for the IRS. The Office of the Inspector General, Social Security Administration shields the identity of people who report suspected fraud. Individuals can make anonymous reports, but their anonymity may impede an agency's ability to investigate the situation thoroughly.
