Last verified 2026-09-14 · every numeric claim independently fact-checked against primary sources · items marked “Not yet verified” are being sourced, never guessed.

1. Documentary Fee / Dealer Processing Charge

Illinois doc fee: $378 statutory cap

CONFLICT FLAGGED: primary-source research and grounded review reported no statutory dollar cap, but adversarial review flagged this as a likely error — Illinois is widely treated as a capped doc fee state with an annually CPI-adjusted maximum documentary fee administered via Secretary of State / dealer regulation authority (recent years approx. $347–$358). Cap set to null pending primary-source verification with IL SOS Vehicle Services / Dealer Licensing. Fee must be disclosed and included in advertised price, and is part of the taxable selling price under the Retailers’ Occupation Tax Act. Verify current-year maximum before publication. | 2026-09-20 council verify: 815 ILCS 505/2L CPI-indexed statutory maximum; $377.63 for 2026 per Illinois AG annual notice (seat with web search). Re-pull every January.

Taxable base: taxable selling price (doc fee included in base); dealer sales taxed under Retailers’ Occupation Tax Act, private-party sales taxed under separate Private Party Vehicle Use Tax schedule (Form RUT-50)

Both sources corroborate the dual structure (ROTA for dealer sales; Private Party Vehicle Use Tax for private sales) but neither verified the numeric rate; 6.25% is the standard Illinois state base rate with local jurisdiction add-ons varying — verify current combined rates with IL DOR.
