Illinois dealer fees: what's capped, what's real, what you can refuse
The short answer
Illinois has no cap we could confirm on the dealer documentation fee. With no limit, the fee is part of the price you negotiate: compare it across dealers and negotiate the out-the-door total. Below: what the law does say, the state's own title and registration fees, and the add-ons you can refuse.

Is there a limit on the doc fee in Illinois?
We couldn't find a Illinois statute or rule that caps the dealer documentation fee. Indexed. The base was $300 on Jan. 1, 2020, adjusted each year by the percentage change in the BLS CPI.
What the dealer has to tell you
Every retail installment contract must include a notice saying the documentary fee is not an official fee and not required by law, giving the $300 base and the annual CPI adjustment, and stating "THIS NOTICE IS REQUIRED BY LAW."
If the fee isn't shown the way the rule requires, that's leverage: point to the rule and ask for it to come off.
Worth checking: Ask the Illinois Attorney General's Consumer Protection Division for the exact 2026 CPI-adjusted maximum, and the Illinois Department of Revenue whether the doc fee is taxable (dealer sources say it is).
Fees you can say no to
Beyond tax, title, registration and the doc fee, most other lines a dealer adds are optional: nitrogen in the tires, VIN etching, paint and fabric protection, "dealer prep", and market adjustments. Ask for them to come off in writing; if they're already on the car, that's a price question, not a fee.
