Buying a vehicle in Illinois comes with more than just the sticker price. Between the state sales tax, local taxes, and registration fees, your final cost can be significantly higher than expected—unless you know how to navigate the system.
This guide breaks down how Illinois vehicle sales tax works, explains county surtaxes, and reveals strategies to help you save thousands on your next vehicle purchase or registration.
Illinois Vehicle Sales Tax Overview
Illinois charges a state sales tax of 6.25% on most vehicle purchases. However, additional local taxes may apply depending on where you live or register the vehicle.
Here’s the general breakdown:
- State sales tax: 6.25%
- Local tax (varies by county and city): Up to 2.75%
- Total potential tax rate: Up to 9% or more in some areas
The total tax is based on either the purchase price or the fair market value of the vehicle, depending on the sale type.
Tax on Dealer vs. Private Sales in Illinois
Illinois distinguishes between vehicle purchases from a licensed dealership and those from a private seller:
- Dealer purchases: Tax is based on the actual purchase price.
- Private party purchases: Tax is based on the vehicle’s age and type, using a flat-rate chart published by the Illinois Department of Revenue.
Example: A private sale of a 6-year-old passenger vehicle would typically be taxed at a flat rate of $90 (as of 2024).

Tips to Save Thousands on Illinois Vehicle Taxes
- Trade-In Credits
Illinois allows trade-in deductions when buying from a dealer. You only pay sales tax on the difference between the new vehicle’s price and the trade-in value. - Buy Privately for Older Vehicles
Private sales of vehicles older than 7 years come with flat-rate tax amounts, often lower than what you’d pay through a dealership. - Register in a Lower-Tax Area (if legal)
Sales tax is based on the registration address, not the dealer location. If you have a second residence or valid out-of-state registration option, this may lower your tax liability. - Avoid Overpaying on Add-Ons
Extended warranties, documentation fees, and accessories may be taxed. Ask for a breakdown and remove what you don’t need. - Use a Registration Service
Services like Ride Legal can help ensure all paperwork is submitted correctly and help you structure your transaction for the biggest legal savings.

What This Means for Your Vehicle Purchase
Illinois has one of the more complex vehicle tax systems in the country due to its many layers of local taxes and split rules for private vs. dealer sales. That means your total tax bill could range from under $100 to several thousand dollars, depending on how and where you buy.
Planning ahead, asking questions, and knowing what exemptions and credits you qualify for can make a major impact on your total cost.
