In this ongoing scam, the perpetrator files a fake information return, such as a Form 1099 Original Issue Discount (OID), to justify a false refund claim on a corresponding tax return. In some cases, individuals have made refund claims based on the bogus theory that the federal government maintains secret accounts for U.S. citizens and that taxpayers can gain access to the accounts by issuing 1099-OID forms to the IRS.
Don't fall prey to people who encourage you to claim deductions or credits to which you are not entitled or willingly allow others to use your information to file false returns. If you are a party to such schemes, you could be liable for financial penalties or even face criminal prosecution.
Frivolous Arguments
Promoters of frivolous schemes encourage taxpayers to make unreasonable and outlandish claims to avoid paying the taxes they owe. The IRS has a list of frivolous tax arguments that taxpayers should avoid. These arguments are false and have been thrown out of court. While taxpayers have the right to contest their tax liabilities in court, no one has the right to disobey the law.
Falsely Claiming Zero Wages
Filing a phony information return is an illegal way to lower the amount of taxes an individual owes. Typically, a Form 4852 (Substitute Form W-2) or a "corrected" Form 1099 is used as a way to improperly reduce taxable income to zero. The taxpayer may also submit a statement rebutting wages and taxes reported by a payer to the IRS.
Sometimes, fraudsters even include an explanation on their Form 4852 that cites statutory language on the definition of wages or may include some reference to a paying company that refuses to issue a corrected Form W-2 for fear of IRS retaliation. Taxpayers should resist any temptation to participate in any variations of this scheme. Filing this type of return may result in a $5,000 penalty.

Misuse of Trusts
For years, unscrupulous promoters have urged taxpayers to transfer assets into trusts. While there are legitimate uses of trusts in tax and estate planning, some highly questionable transactions promise reduction of income subject to tax, deductions for personal expenses and reduced estate or gift taxes. Such trusts rarely deliver the tax benefits promised and are used primarily as a means of avoiding income tax liability and hiding assets from creditors, including the IRS.
IRS personnel have seen an increase in the improper use of private annuity trusts and foreign trusts to shift income and deduct personal expenses. As with other arrangements, taxpayers should seek the advice of a trusted professional before entering a trust arrangement.
