Illinois tax, title, and license fees break into three separate charges

When you buy a vehicle in Illinois, you pay three distinct fees at the time of purchase: sales tax on the vehicle itself, a title fee to register ownership with the state, and a license plate fee. The total you owe depends on the vehicle's price, its age, and whether you're buying from a dealer or a private seller. Illinois does not have a single "tax, title, and license" package — each piece is calculated separately and collected by different parts of the state system.

The largest piece is almost always sales tax. Illinois charges 6.25 percent state sales tax on vehicle purchases, though some counties and municipalities add their own local tax on top of that. A $20,000 vehicle will cost you at least $1,250 in state sales tax alone, plus whatever local tax applies in your area. The title and license fees are much smaller — typically under $300 combined — but they are mandatory and non-negotiable.

Key Takeaways

  • Illinois state sales tax on vehicles is 6.25 percent, and your county or city may add local tax on top of that amount.
  • The title fee in Illinois is $150 for a new title and $50 for a duplicate or transfer, depending on your transaction type.
  • License plate fees range from $98 to $248 per year depending on vehicle weight and whether you choose a standard or specialty plate.
  • You pay sales tax on the full purchase price, even if you trade in another vehicle — the trade-in reduces the taxable amount only if the dealer reports it correctly.
  • Private sales are subject to the same sales tax as dealer sales in Illinois, and you must pay it when you register the vehicle with the Secretary of State.

Sales tax rates vary by county and city

The 6.25 percent state rate is the floor. Cook County (which includes Chicago) adds 1.25 percent, bringing the total to 7.5 percent in unincorporated areas. Within Chicago itself, the city adds another 1.25 percent on top of that, for a combined rate of 8.75 percent. Other counties and cities have their own local rates, ranging from zero additional tax to as much as 2 percent.

To find your exact rate, you need to know both your county and your city or village. The Illinois Department of Revenue publishes a complete tax rate table by municipality on its website. If you are buying from a dealer, they will calculate the correct rate for your location. If you are buying privately and registering the vehicle yourself, you will owe the tax based on where you register it, not where you bought it.

Sales tax is calculated on the purchase price of the vehicle. If you trade in another car, the trade-in value reduces the taxable amount — you pay tax only on the difference. For example, if you buy a $25,000 vehicle and trade in a car worth $5,000, you pay sales tax on $20,000, not $25,000. This applies whether you buy from a dealer or a private seller, but only if the transaction is properly documented.

Title fees depend on whether you are transferring or creating a new title

The Illinois Secretary of State charges $150 to issue a new title when you buy a vehicle. This is the standard fee for any first-time registration of a vehicle in Illinois. If you already own a vehicle registered in Illinois and you are transferring the title to a new owner, the fee is still $150 for the new owner.

A duplicate title — issued when you have lost or damaged your existing title — costs $50. A corrected title, issued when information on your existing title is wrong, also costs $50. These lower fees explore only to replacements of titles you already hold, not to new registrations.

The title fee is separate from registration. You pay the title fee once, when the vehicle is first registered in your name. You do not pay it again unless you sell the vehicle to someone else or you need a replacement copy of your title document.

License plate fees are annual and based on vehicle weight

Illinois charges an annual license plate fee that depends on the vehicle's gross vehicle weight rating (GVWR), not its actual weight. A passenger car typically falls into the lowest weight class and costs $98 per year. A pickup truck or SUV might cost $123 to $173 per year depending on its GVWR. Heavy trucks can cost $248 or more per year.

You pay this fee every time you renew your registration, which in Illinois happens every two years. When you first register a vehicle, you pay the full two-year fee upfront. If you register mid-year, some counties prorate the fee, but this varies by location — ask the Secretary of State's office or your local vehicle registration facility.

Specialty plates — such as environmental plates, veteran plates, or personalized plates — may cost more than the standard plate fee. A personalized plate, for example, costs an additional $25 per year on top of the standard license fee. Environmental plates typically cost the same as standard plates but may have different renewal terms.

When you buy from a dealer versus a private seller

A dealer collects all three charges — sales tax, title fee, and license fee — at the time of sale and handles the registration with the Secretary of State on your behalf. You leave the lot with temporary plates and receive your permanent registration documents by mail within two to three weeks. The dealer's paperwork must show the correct sales tax rate for your location.

When you buy from a private seller, you are responsible for paying sales tax and the title fee yourself. You must take the bill of sale, the seller's title document, and proof of insurance to a Secretary of State facility or an authorized vehicle registration facility. You pay the sales tax and title fee at that time, and you receive your new title and license plates. This process typically takes one to two hours at the facility.

In both cases, you owe the same total amount in taxes and fees. The difference is who collects the money and when. Dealers collect everything upfront; private sales require you to handle registration yourself and pay the state directly.

Trade-ins and how they affect your total cost

If you trade in a vehicle, the trade-in value is subtracted from the purchase price before sales tax is calculated. A $25,000 vehicle with a $5,000 trade-in means you pay sales tax on $20,000, not $25,000. This applies to both dealer and private sales, though private sales are less common for trade-ins.

The title fee and license fee do not change based on trade-in value. You still pay $150 for the new title and the annual license fee based on the new vehicle's weight. The trade-in affects only the sales tax calculation.

If you owe money on your trade-in vehicle — if you have an outstanding loan — the dealer will typically pay off that loan from the trade-in credit before calculating your out-of-pocket cost. This does not affect the sales tax calculation, but it does affect how much cash you need to bring to the transaction.

What happens if you buy out of state and bring the vehicle to Illinois

If you buy a vehicle in another state and register it in Illinois, you still owe Illinois sales tax. The state taxes the purchase price of the vehicle, regardless of where you bought it. You pay this tax when you register the vehicle with the Secretary of State, not when you buy it.

If you already paid sales tax in the state where you bought the vehicle, Illinois will give you a credit for that amount, up to the Illinois rate. For example, if you paid 5 percent tax in another state and Illinois charges 7.5 percent in your county, you owe an additional 2.5 percent to Illinois. If you paid 8 percent in another state and Illinois charges 7.5 percent, you owe nothing more — you have already paid more than Illinois requires.

You still pay the $150 title fee and the annual license fee when you register in Illinois. These fees do not change based on where the vehicle was purchased.

Frequently Asked Questions

Do I have to pay sales tax if I buy a vehicle from a family member?

Yes. Illinois taxes all vehicle purchases, including those from family members, at the same rate as dealer sales. The only exception is if the vehicle is being transferred as a gift with no money changing hands — in that case, you pay the title fee but not sales tax. You must have documentation showing it was a gift, not a sale.

What if I buy a vehicle in one Illinois county and register it in another?

You pay the sales tax rate of the county where you register the vehicle, not where you bought it. If you buy in Cook County but register in DuPage County, you pay DuPage's rate. This matters most when buying from a private seller, because the seller's location does not determine your tax rate.

Can I get a refund if I return the vehicle within a certain time?

Illinois does not have a mandatory cooling-off period for vehicle purchases. If you buy from a dealer and the dealer offers a return policy, that is the dealer's choice, not a legal requirement. Sales tax and registration fees are not refunded unless the sale itself is reversed through a formal dispute or fraud claim.

Do electric vehicles pay a different license fee?

Electric vehicles pay the same license plate fee as gasoline vehicles of the same weight class. There is no tax break or discount for electric vehicles at the state level, though some municipalities offer local incentives. Check with your city or county for any local programs.

What if the dealer made a mistake on the sales tax amount?

Contact the dealer when ready. If the dealer charged you the wrong rate, they are responsible for correcting it with the state and refunding or collecting the difference from you. If you registered privately and the Secretary of State facility charged the wrong rate, you can file a claim with the Illinois Department of Revenue for a refund, though this process can take several months.
