STATE AND LOCAL TAX UPDATE – Illinois Increases Taxes

by Michael H. Israel, M.A.,J.D., LL.M

The Illinois Department of Revenue has issued an information bulletin regarding the new Illinois income tax rates.  These rates became effective July 1, 2017

Regarding individuals, trusts, and estates, the Illinois Income Tax is increasing from 3.75 percent (.0375) to 4.95 percent (.0495).

Regarding corporations (excluding S corporations), the Illinois Income Tax is increasing from 5.25 percent (.0525) to 7 percent (.07).

Guidance has also been issued as to how estimated payments are impacted by the mid-year tax increases as well as the impact on the apportionment method of calculating income. 

Please feel free to contact us to discuss how these issue may impact you.  

State and Local Tax Reminder about State Income Tax Residency

At DUGGAN BERTSCH, LLC, we are often asked by clients to explain the process by which a taxpayer can establish a “new” state residency for income tax purposes. 

Sometimes we are asked to explain the impact of moving to a new state altogether  or about the impact of remaining in your current state of residence while spending significant amounts of time in another or several other states. 


Our firm represents both individuals as well as numerous and varied business entities.  While determining state tax obligations is always a complex process, when a taxpayer has income from sources in multiple states, the complexity greatly increases.  Past considerations relied upon “physical presence” as the main factor in determining tax reporting obligations - those days have quickly changed.  Some states now assert obligations based upon “economic presence”.
