Tax Returns

In accordance with URPO Ruling #5, effective 1/1/2016 tax collectors and taxpayers must file their tax returns electronically. If you need to file an amended return for a previous year, please contact our Customer Service unit at 312-747-4747 to obtain the appropriate form(s).


Instructions for Submitting Final Returns 

If your business is closed, a final return must be filed for each tax for which the business is registered within 45 days of the date your business ceased operations.  In addition, a Business Change Form and an Affidavit for Final Tax Period must be completed if you are closing or selling your business.  Note: all taxes for which the business is registered should be included on the Affidavit for Final Tax Period.

If you are selling your business, a Bulk Sales Notice must be filed at least 45 days prior to the date of sale or transfer on a form provided by the department.

For questions regarding these forms please call 312.747.4747.
