Report suspected abusive tax promotions or preparers The IRS warns you to look out for promoters who peddle false hopes of large tax deductions from abusive arrangements. These "deals" are generally marketed by unscrupulous promoters who make false claims about their legitimacy and charge high fees to boot. These promoters frequently devise new ways to cheat the system and market them aggressively. Some taxpayers play the audit lottery hoping they don't get noticed. Promoters make statements relating to a tax benefit or a gross valuation overstatement that they know or should know are false or fraudulent. They often promise to eliminate or substantially reduce your tax liability. We rely on you to help us identify promoters of “too good to be true” tax schemes and tax preparers using improper methods to avoid paying taxes. Help us protect American taxpayers from unscrupulous individuals who promote improper and abusive tax schemes as well as tax return preparers who deliberately prepare improper returns by reporting them to us. Examples of what to report Many promotions are complex and involve improper flow-through entities such as trusts and limited liability companies. They disguise the true ownership of income or assets. Other schemes are less complex involving the sale of low value photograph prints or inappropriate claims for refund or credit. Examples include: Abusive syndicated conservation easements Abusive micro-captive arrangements Potentially abusive use of the U.S.-Malta tax treaty Improper claims of business credits Improper monetized installment sales For detailed information on the tax schemes listed above as well as other schemes not listed here, visit the IRS Dirty Dozen page.
