You can find all of the information you need to report a tax cheat at the IRS Whistleblower website. If you want to report some possible tax fraud activity just for the fun of it (without claiming a reward) use IRS Form 3949-A.

The person can contact the IRS for concrete or suspected violations, and the organization will most likely launch an investigation of the accused party. The phone number to call and report such things is 1-800-829-0433. The IRS also has a special form that the person can complete and send to a special address. An interested person can call 1-800-829-3676 to order the special form.
