How do I Report Someone Who Is Lying on Their Indiana IRS Taxes?

It is your responsibility to report anyone you suspect of tax fraud to the IRS.

Lying on your income tax return is called fraud, and tax fraud is a serious offense in the United States. Taxpayers that commit tax fraud and are caught doing so face hefty fines and possible jail time. If you suspect a resident of Indiana, or any state, of committing tax fraud, it is your duty to report that person to the Internal Revenue Service. An investigation of the alleged person or persons will take place to determine whether fraud was committed. If so, that person or persons will face monetary fines and time in jail.

Instructions

1. Obtain form 3949-A from the Internal Revenue Service website. This form is used to report taxpayers suspected of committing tax fraud. If you do not want to file form 3949-A, you can compose a letter to the IRS instead.

2. Enter the information on form 3949-A or on your letter to the IRS, including the name and address of the person you suspect of committing fraud, the taxpayer identification number of that person, a description of why you suspect fraud, the year or years the taxpayer allegedly committed fraud and an estimate of the amount of any unreported income. Your personal information is requested, though it is not required.

3. Mail either form 3949-A or your composed letter to the Internal Revenue Service at:

   Internal Revenue Service
