How to Register a Business in Illinois

If you want to create a legal entity for your business in Illinois, you have several options. A Illinois Limited Liability Company, or LLC, provides key legal protections for your company while requiring a minimum of paperwork.

A Illinois Corporation provides all of the legal protections of an LLC, in addition to special treatment as a full business entity for accounting and tax purposes, at the cost of slightly more paperwork and reporting requirements.
