Frequently asked
Is the doc fee capped in Illinois?
Yes. Illinois limits the documentation fee by law: capped (indexed yearly; ~$360). A doc fee above the cap on your contract is a compliance problem — point it out and ask for it to be corrected.
How much is sales tax on a used car in Illinois?
6.25% state + local. Tax is a government charge, not dealer profit — but check that it is calculated on the correct price, with any trade-in credit applied where Illinois allows it.
Which dealer fees can I refuse in Illinois?
Government charges (sales tax, title, registration) are fixed. Everything else — doc fee, dealer prep, VIN etching, paint protection, nitrogen tires, appearance packages — is dealer profit. You may not get individual lines removed, but you can negotiate the out-the-door total down to offset them, or walk away.
What is a fair out-the-door price in Illinois?
Take the agreed vehicle price, add Illinois's tax (6.25% state + local), title (~$165), and registration, plus a doc fee in line with capped (indexed yearly; ~$360). If the quote is meaningfully above that math, ask the dealer to walk you through every added line.
Figures are typical published amounts as of 2026-07-03 and can change with legislation or local rates. Always verify current caps, tax rates, and fees with the Illinois DMV or your county before signing.
