IL SB3009

Adds a new income tax credit for qualified teachers equal to 50% of tuition costs incurred at Illinois public universities, effective for taxable years ending December 31, 2020 and later.

Limits annual credit usage to no more than 20% of the qualified teacher's aggregate credit amount per taxable year.

Defines "qualified teacher" as an individual who graduated from an Illinois public university, is currently employed as a teacher in Illinois, and has worked as a teacher in the state for at least 5 consecutive years.

Allows unused credits exceeding tax liability to be carried forward and applied to the next 5 taxable years, with earlier credits applied first.

Credit cannot reduce tax liability below zero and is exempt from the sunset provisions of Section 250.
