File Using Tax-Prep Software

 
 

You may choose to file online using computer tax preparation (Tax-Prep) software. This allows you to file your IL-1040 electronically using department approved commercial software or web-based applications. In some instances, the commercial software can be downloaded from the software company's web site. Some providers of Tax-Prep software may charge a fee for their service.
