Do You Pay Taxes When You Buy a Car From a Private Seller in Illinois?

When you buy a car and register it in Illinois, you owe sales tax—whether you purchase it from a dealer or a private seller. The tax law does not make a distinction for private-party vehicle sales.

The statewide sales tax on vehicles in Illinois currently stands at 6.25% of the purchase price of the car. For example, if you buy a used car from a private party for $10,000, you’ll pay $625 in sales tax plus local (city and county) tax, depending on where you live in the state.

The total vehicle sales tax in Illinois is at its highest at 11.5% in such towns as Harvey, Harwood Heights, and Matteson. If you’re thinking about buying a car in Chicago, you’ll have to pay the state tax (6.25%), local taxes (3% in city and county rates), and an additional 1% in special district tax for a total of 10.25%.

You’ll find the lowest sales tax rates in cities like Robinson and Momence, which don’t levy local tax, and whose citizens pay the 6.25% state tax rate only.

Here is a table of total car sales tax rates for the ten largest cities in Illinois:

How is Used Car Sales Tax Calculated in Illinois?

Sales taxes are assessed as a percentage of the vehicle’s purchase price. If you think you can outsmart the state by negotiating a low “official” purchase price and paying the remainder in a side transaction, think again. The Illinois Department of Motor Vehicles is way ahead of you.

Understanding Fair Market Value

The Illinois Department of Motor Vehicles has the option of using the car's "fair market value" (not the car price) as the basis for calculating sales tax. The DMV establishes what the car is worth on the open market by referring to the Kelley Blue Book or other reliable sources of information about used car prices. If the DMV concludes that the car's fair market value is greater than the purchase price, the sales tax can be assessed based on the fair market value.

If you’re buying the car from a private party, you should declare the car's fair market value to the DMV and pay the appropriate amount of sales tax based on that value. Failing to do so may result in fines and penalties.

Is the Sales Tax the Same as Use Tax?

In Illinois, “sales tax” and “use tax” both refer to a tax paid on the purchase of a product or service. Are they exactly the same thing? The official website is about as clear as mud on the issue. If you’ve recently purchased a used car in Illinois, you owe sales tax—or use tax—to the DMV when you register it. Call it what you will; you’ll be paying the state’s 6.25% plus any applicable local taxes in any case.

The rate for private party vehicle use tax is determined by the car's fair market value or the purchase price. Where the stated price is not available (as in the case of a gift), the Illinois DMV will calculate the use tax rate based on the fair market value. If the vehicle’s price is less than $15,000, the tax is based on the age of the vehicle. If the vehicle purchase price is $15,000 or more, the tax is based on the purchase price.

How to Avoid Paying Sales Tax on a Car in Illinois?

Sorry to break it to you, but unless you qualify for an exemption, there is no way to legally avoid paying sales tax on used cars in Illinois or in any other state where sales tax is levied.

Who is Exempt From Paying Taxes in IL?

You can avoid paying sales tax if your vehicle purchase falls into any of the following categories:

You are a member of a tax-exempt organization. To be exempt from state and municipal sales taxes, a business must be non-profit and operated exclusively for charitable, religious, educational, or governmental reasons. The organization must submit their request and complete the Application for Tax Sales Exemption Form (STAX-1).
Federal, state, and local governments are exempt from paying sales tax when buying motor vehicles. They must provide the dealer with a purchase order or letter of authorisation on official letterhead at the time of purchase.
The vehicle was designed for use on farms and is mostly utilized for agricultural output.
The buyer relocated to Illinois from another state, and the vehicle was driven in another state for at least three months.
If someone buys a car in Illinois, immediately moves to another state, and registers the car in their new state, they will not pay Illinois sales tax. If their new state of residence charges sales tax, they will pay it per that state’s tax rate.
The car was a gift from an estate to the surviving spouse.
The buyer is not an Illinois resident and will register the car in a different state and pay sales tax as per that state’s tax, if applicable.

The state of Illinois will expect appropriate documentation to substantiate any qualifying tax exemptions, so have your paperwork in order when you go to register your vehicle and transfer the title.

Moving to a State With No Vehicle Sales Tax

Moving to a state with no sales tax is the best way to avoid paying taxes on used cars. Alaska, New Hampshire, Oregon, Delaware, and Montana do not charge sales taxes on vehicle purchases.

If you plan to move to one of these states, you should postpone purchasing a car until after the move. Otherwise, we don't recommend attempting to avoid paying car sales tax in Illinois or anywhere else. The thousands of dollars you might save are not worth the legal and financial implications, nor the loss of your peace of mind.

How to Pay Illinois Vehicle Sales Tax

Here's how to pay car sales tax in Illinois after you’ve purchased a used car from a private seller:

1. You and the seller each complete the Vehicle/Vessel Bill of Sale. When you buy the car on PrivateAuto, we provide an official Washington bill of sale and prompt both of you to sign it in our app at the appropriate stage of the transaction process.
2. Calculate the amount of sales tax due depending on the tax rate for your city and county. The Illinois sales tax rate on cars is 6.25 percent. To figure out how much the sales tax is, multiply the price of the car by 0.0625, but if you’re subject to local sales tax, add the local rate (divided by 100) to this number before multiplying the price of the car by it. Or just use our sales tax calculator to make things easier.
3. Complete the Sales Tax Transaction Return (Form ST-556) for the motor vehicle that must be titled and registered by an agency of the Illinois state government.
4. Bring the completed form, along with the computed sales tax amount, to the county tax office.
5. Pay the sales tax and any other fees that apply, such as title and registration fees.
6. Get a receipt for your payment.
7. If applicable, the county tax office will process your payment and provide your registration and license plates.
8. Once you've paid the sales tax and turned in the necessary paperwork, you'll get your new registration and title for the car. The title and registration will show that you bought the car and that the sales tax has been paid. You will also get new license plates.

Many people think buying from car dealers is much easier than preparing all the paperwork yourself. It’s true that dealers are awfully convenient at handling the paperwork, but you pay way more when you go to a dealer.

What’s more, dealerships charge a "documentation fee" above and beyond the taxes you pay to the state. The documentation fee in Illinois goes as high as $300.

Avoid documentation fees and get lower prices when you buy used cars from private sellers right here on PrivateAuto.
