Does Illinois Offer a Pass-Through Entity Tax Election?
Yes. The current Illinois profile lists a pass-through entity tax election with a rate of 4.95%.
What the Current State Tax Profile Shows
Publication 129 is the checked-in source for Illinois pass-through entity treatment in this rollout.
Why This Matters for LLC Owners
LLC owners often look only at federal pass-through treatment and miss the separate state layer. The checked-in tax profile for Illinois is meant to reduce that risk by keeping the rate, election, registration, and source-link details in structured JSON that can be refreshed later.
