How to Report a Person Not Filing Income Taxes in Missouri

Filing income tax is required.

Paying income tax is a necessary part of being employed or owning a business in the U.S. Tax fraud is a crime that cheats the Internal Revenue Service (IRS) out of millions of dollars each year. If you become aware of an individual or business in Missouri that is not filing income taxes, there are a few different ways to initiate the reporting process. Be sure that your assumptions are valid and that your information is correct prior to initiating any type of complaint or report.

Things You'll Need

• Stationery supplies
• Postage

Instructions

1. Contact the Missouri State Department of Revenue by telephone at 573-751-3505. Let the operator know that you wish to report an individual who is not filing income taxes. Have as much information on the individual as possible prior to calling. Alternatively, you can mail a letter to the Missouri State DOR at:

   Individual Income Tax
   P.O. Box 2200
   Jefferson City, MO 65105-2200

2. Fill out IRS form 3949 A, also known as the Information Referral Form. The Internal Revenue Service (IRS) has this form available to download and print from its website at no charge. Once you have filled out this form accurately and completely, you can mail it in to the IRS office at:

   Internal Revenue Service
   Fresno, CA 93888

3. Write a letter to the IRS if you would prefer not to fill out form 3949 A. Be sure to include information in your letter, such as the name and address of the person you are reporting, the dollar amount that you feel is not being claimed and any information related to the person's business that may be helpful. Mail this letter to the IRS office at:

   Internal Revenue Service
   Fresno, CA 93888

4. Mail a follow-up letter to the IRS one month after sending in your complaint. This should allow the IRS ample time to investigate and the IRS should be able to verify that it has received your complaint. You may receive an acknowledgment in the mail prior to the follow-up letter if the IRS has already processed your complaint.

Tips & Warnings

• You do not have to include your name when reporting an individual or business to the IRS. You have the right to remain confidential.

• False reporting is a crime. Be accurate with all information that you provide to the IRS.
