The IRS maintains an abusive tax shelter hotline that people can use to provide information (anonymously, if preferred) about abusive tax shelter transactions. The Office of Tax Shelter Analysis is primarily interested in in potentially abusive transactions that may be employed by many taxpayers and could pose a significant compliance risk to the IRS.
Don't use this hotline if you want to report an individual or company that you suspect or know isn't complying with the tax laws or has failed to pay the tax that they owe. Please refer to Reporting Suspected Tax Fraud and Whistleblower Informant Awards for more information on reporting these individuals or companies.
