Should I form my LLC in Illinois or another state?

If you conduct business primarily in Illinois, form your LLC here. Forming in another state (Wyoming, Delaware, New Mexico) and then operating in Illinois requires paying foreign registration fees in Illinois anyway — you end up paying both states' fees.
