The Quick Answer: Buying a used car out of state (such as in Indiana, Wisconsin, or Missouri) does not allow Illinois residents to avoid local sales taxes. Under Illinois Department of Revenue guidelines, sales and use taxes are determined strictly by the buyer’s home address upon registration via Form RUT-25. If you pay 7.0% tax in Indiana, Cook County will legally recapture the remaining 1.25% to 3.25% difference before the Secretary of State issues metal license plates. Once you factor in travel time, temporary transit tags ($30–$75), out-of-state electronic titling surcharges, and mandatory Illinois EPA emissions testing, purchasing out of state frequently costs $800 to $1,500 more than buying locally. At Autos of Chicago in Arlington Heights, our on-site electronic titling desk eliminates all registration friction, and our Black Friday Sale (live through November 30, 2026) delivers $1,000 to $2,500 off inventory with financing starting at 4.99% APR.
When shopping for a used vehicle online, it is easy to spot a car in Milwaukee, Indianapolis, or Gary advertised for $500 less than local listings in Arlington Heights or Schaumburg. Many Chicago-area buyers assume that by traveling across state lines, they can escape Cook County’s local sales tax rates or snag a regional bargain.
However, cross-border vehicle transactions carry complex legal and financial tax-recapture mechanisms enforced by the Illinois Department of Revenue and the Secretary of State.

The Reality of Illinois Form RUT-25: How Taxes Are Recaptured
The State of Illinois enforces strict statutory use-tax laws to prevent residents from shopping out of state to avoid local taxation:
-
1. Tax Is Based on Your Home Address:
Even if you sign purchase contracts in Wisconsin (where state sales tax is 5.0%), the Illinois Department of Revenue requires you to file Form RUT-25 upon bringing the vehicle home. Illinois assesses use tax based strictly on where the vehicle is garaged. If you live in Arlington Heights, you owe Cook County’s local tax rate. -
2. Out-of-State Reciprocity Credits:
Illinois grants credit for sales tax legally paid to another state up to the Illinois state rate. However, if the out-of-state rate was lower than your local Cook County rate, you must pay the remaining balance to the Illinois Department of Revenue before the Secretary of State will release your license plates. -
3. The 30-Day Filing Penalty:
Form RUT-25 must be submitted within 30 days of the vehicle crossing state lines. Failing to file within 30 days incurs immediate late-filing financial penalties and interest charges from Springfield.
