It presents concise coverage of the taxes of major interest including: personal income tax, corporate income tax, and sales and use taxes. Other Illinois taxes are summarized, as well, including the administration and imposition of city of Chicago taxes, with particular emphasis placed on persons or transactions subject to the tax, the basis and rate of tax, and the new annual return provisions. New with the 2003 Edition, the Guidebook includes additional practical tips, pointers and examples to practitioners by Marilyn A. Wethekam, Esq. of Horwood Marcus & Berk in Chicago. This valuable new commentary helps practitioners further apply the complex principles of Illinois tax law to specific practice situations. For the user's convenience in determining what is new in the Illinois tax law, a special Highlights of Tax Changes section is included to provide at-a-glance awareness of key legislative developments in the law. While this handbook focuses on the law applicable to the filing of income tax returns in 2003 for the 2002 tax year, legislative changes effective after 2002 are also noted with an indication of the effective date to avoid confusion and to assist in future tax planning. Helpful references to both the Illinois and related federal provisions are provided throughout for those who wish to more fully examine explanations and text of the applicable law. Also, detailed Tables of Contents, Law and Regulations Finding Lists, a Topical Index, and an organized presentation of the content combine to make pinpointing critical information quick and easy.
