What is Illinois Sales Tax on Used Cars?
The Illinois sales tax on used cars is a mandatory tax levied by the state and local governments on the retail sale of pre-owned vehicles. When you purchase a used car in Illinois, whether from a dealership or a private seller, a percentage of the vehicle’s selling price is collected as sales tax. This tax revenue helps fund public services across the state.
Understanding this tax is crucial for budgeting your vehicle purchase accurately. It’s important to note that the sales tax applies to the purchase price, not necessarily the book value of the car. For most buyers, this calculator simplifies the process of estimating these costs.
A common misunderstanding revolves around the tax rate. While the state rate is fixed, various counties and municipalities in Illinois impose their own additional sales taxes. This calculator helps account for both the base state rate and any supplementary local rates you might encounter. Ignoring these local taxes can lead to unexpected expenses when registering your vehicle.
This calculator is designed for anyone purchasing a used car in Illinois, including private individuals and those buying from licensed dealerships. It clarifies the breakdown of state and local taxes, providing a transparent view of the total tax burden.
Illinois Used Car Sales Tax Formula and Explanation
The calculation for Illinois sales tax on used cars is straightforward but requires attention to both state and local rates. The primary formula is:
Total Sales Tax = (Vehicle Price × State Tax Rate) + (Vehicle Price × Additional Local Tax Rate)
This can be simplified to:
Total Sales Tax = Vehicle Price × (State Tax Rate + Additional Local Tax Rate)
And the estimated total cost, often referred to as the “out-the-door” price, is:
Total Out-the-Door Price = Vehicle Price + Total Sales Tax
Variables Explained:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Vehicle Price | The agreed-upon selling price of the used vehicle. | $ (Currency) | $1,000 – $50,000+ |
| State Tax Rate | The mandatory base sales tax rate set by the State of Illinois. | % (Percentage) | 6.25% |
| Additional Local Tax Rate | Extra sales tax rates imposed by counties, municipalities, or special districts within Illinois. | % (Percentage) | 0% – 4.75% (or higher in some areas) |
| Total Sales Tax | The combined amount of state and local sales tax due. | $ (Currency) | Calculated |
| Total Out-the-Door Price | The final price including the vehicle cost and all applicable sales taxes. | $ (Currency) | Calculated |
Practical Examples
Example 1: Standard Purchase
Sarah buys a used car for $12,000. She lives in a region of Illinois with only the standard state sales tax.
- Vehicle Price: $12,000
- State Tax Rate: 6.25%
- Additional Local Tax Rate: 0.00%
Calculations:
- State Sales Tax = $12,000 × 0.0625 = $750.00
- Additional Local Tax = $12,000 × 0.00 = $0.00
- Total Sales Tax = $750.00 + $0.00 = $750.00
- Estimated Total Out-the-Door Price = $12,000 + $750.00 = $12,750.00
Sarah will pay an estimated $750.00 in Illinois sales tax.
Example 2: Purchase with Higher Local Taxes
John purchases a used SUV for $25,000. He lives in a Chicago suburb that has an additional 1.75% local sales tax on top of the state rate.
- Vehicle Price: $25,000
- State Tax Rate: 6.25%
- Additional Local Tax Rate: 1.75%
Calculations:
- Combined Tax Rate = 6.25% + 1.75% = 8.00%
- Total Sales Tax = $25,000 × 0.0800 = $2,000.00
- Estimated Total Out-the-Door Price = $25,000 + $2,000.00 = $27,000.00
John will pay an estimated $2,000.00 in Illinois sales tax.

Key Factors That Affect Illinois Used Car Sales Tax
- Vehicle Purchase Price: This is the most significant factor. The higher the price you pay for the car, the greater the sales tax amount will be, as the tax is a direct percentage of this price.
- Base State Sales Tax Rate: Illinois has a uniform state sales tax rate of 6.25% applicable to most retail sales, including used vehicles. This rate is a foundational component of the total tax.
- Local Sales Tax Rates (County/Municipal): This is a critical variable. Different counties, cities, and even special districts within Illinois impose their own sales taxes. These rates vary widely and can significantly increase the total tax burden. For instance, taxes in the Chicago metropolitan area are often higher than in more rural regions. Always verify the combined rate for your specific delivery location.
- Delivery Location: The sales tax rate applied is typically based on the location where the vehicle is delivered or principally used, especially if purchased online or out-of-state but brought into Illinois. Ensure you are using the rate for the correct jurisdiction.
- Exemptions (Rare for Private Sales): While most used car sales are taxable, certain specific situations might involve exemptions (e.g., sales between immediate family members in some cases, or certain non-profit organizations). However, for the vast majority of private and dealer sales, tax is due. Check with the Illinois Department of Revenue for details on specific exemptions.
- Trade-in Value: In Illinois, the sales tax is generally calculated on the full purchase price of the vehicle, *before* any trade-in value is applied. Unlike some other states, you don’t deduct the trade-in value from the taxable amount. You pay tax on the price of the new car and potentially also on the value of the car you traded in (depending on how the transaction is structured). This calculator assumes tax is applied to the stated purchase price.
