What is the difference between a federal and state change when filing Form IL-1040-X?

A federal change is anything that pertains to your federal filing status, adjusted gross income, exemption allowance, and earned income credit. A state change is when you are not required to file a federal Form 1040-X, Amended U.S. Income Tax Return. An example is an error is made in calculation of credit, such as the property tax credit or the education expense credit. Another example is if you failed to claim a subtraction on your Form IL-1040 for retirement income shown on lines 4b, 5b, and 6b of your original federal Form 1040, Page 1.
