How do I respond to a notice from IDOR that increases the private party tax due on a vehicle I purchased or was gifted?

If you purchased a motor vehicle from or were gifted a motor vehicle by a private party and received an assessment from the Illinois Department of Revenue for increased tax due based on the fair market value of the vehicle, respond to the notice with a signed copy of your bill of sale or a fair market value appraisal from a licensed dealer to support the tax originally remitted with your Form RUT-50, Private Party Vehicle Use Tax Transaction Return.

Form RUT-49, Vehicle Transaction Affidavit, is available to verify information reported or provide information not reported on Form RUT-50. This form can also be used in lieu of a bill of sale for Form RUT-50. 

You may also complete and file Form RUT-50-X, Amended Private Party Vehicle Use Tax Transaction Return, or complete the IDOR-1-TRN, Return Correction Notice, that is issued when you receive an assessment on Form RUT-50 to make any necessary changes to information on your return.

See the instructions to Form RUT-50 for a list of exemptions and exceptions to the standard tax calculations on Form RUT-50. When marking an exemption or exception on Form RUT-50, ensure that the correct exemption or exception is clearly indicated/circled, and provide any supporting documentation you may have.

You may access additional information by searching the entire Illinois Department of Revenue website.

If you have additional inquiries, you may submit them on the Questions, Comments, or Requests form.
