Illinois registration fees depend on vehicle weight and age

Illinois charges registration fees based on the gross vehicle weight rating (GVWR)—the maximum weight your vehicle is designed to carry, not what it actually weighs. A passenger car typically falls into the 3,001 to 4,000 pound category, while SUVs and trucks often land in higher brackets. The older your vehicle, the lower the fee, because Illinois reduces registration costs for cars over 10 years old.

The state also charges a $20 vehicle use tax on top of the registration fee itself. This is separate from the registration cost and applies to all vehicles. If you're registering a vehicle for the first time in Illinois, you'll pay both the registration fee and the use tax together.

Exact dollar amounts vary by weight class and vehicle age, so the best way to know your specific cost is to check the Illinois Secretary of State website or contact your local Secretary of State office. They can tell you the fee for your vehicle's GVWR and age before you renew.

Key Takeaways

  • Illinois registration fees are based on your vehicle's gross vehicle weight rating, not its actual weight, with heavier vehicles costing more to register.
  • Vehicles over 10 years old pay a reduced registration fee compared to newer cars in the same weight class.
  • All registrations include a separate $20 vehicle use tax on top of the base registration fee.
  • The Secretary of State website or your local office can tell you the exact fee for your specific vehicle before you renew.

How weight class affects what you pay

Illinois divides vehicles into weight brackets, and each bracket has its own fee schedule. A sedan weighing 3,500 pounds falls into a different category than a pickup truck rated at 6,000 pounds, and the truck owner will pay more. The GVWR is listed on a label inside the driver's door jamb or in your owner's manual—not the actual weight of your car right now.

The fee difference between weight classes can be $20 to $40 or more per year, depending on which brackets you're comparing. If you're buying a vehicle and registration cost matters to you, checking the GVWR before purchase gives you a real sense of what you'll pay annually.

Discounts for older vehicles

Once your vehicle reaches 10 years old, Illinois reduces the registration fee. The reduction is significant enough that owners of older cars pay noticeably less than owners of newer ones in the same weight class. This discount continues as long as you own and register the vehicle in Illinois.

The age is calculated from the model year, not the purchase date. A 2014 model year vehicle became may be able to access for the reduced rate in 2024. If you're unsure whether your vehicle qualifies, the Secretary of State office can confirm based on your vehicle identification number (VIN).

Vanity plates and specialty registration options

Illinois offers personalized license plates with custom letter and number combinations. These cost more than standard plates—typically an additional fee beyond your base registration. The exact amount depends on the specific combination you choose and whether it's a standard personalized plate or a specialty design.

The state also offers specialty plates supporting various causes, military service, and organizations. These plates may have different fee structures than standard registration. If you're interested in a specialty plate, the Secretary of State website lists all available options and their associated costs.

What happens if you register late

Illinois allows a grace period after your registration expires, but driving on an expired registration is illegal and can result in a traffic citation. If you renew after the expiration date, you may owe a late fee in addition to your regular registration cost. The amount of the late fee depends on how long past the expiration date you renew.

Registrations expire on your birthday each year, and the state sends renewal notices before that date. Setting a calendar reminder a month before your birthday helps you avoid the rush and any late fees. You can renew online, by mail, or in person at a Secretary of State office.

Online renewal and payment methods

The Illinois Secretary of State website allows you to renew your registration online if your vehicle is may be able to access. Not all vehicles may have access to for online renewal—commercial vehicles, vehicles with liens, and some other categories must renew in person or by mail. The website will tell you whether your vehicle is may be able to access when you enter your license plate number.

Online renewal is faster than visiting an office in person, and you can pay by credit card, debit card, or electronic check. The state charges a small online processing fee in addition to your registration and use tax. If you choose to renew by mail, you'll need to include a check or money order.

Registering a vehicle you just bought

When you purchase a vehicle in Illinois, you have 30 days to register it. During that 30-day period, you can drive with the dealer's temporary registration or a bill of sale. After 30 days, you must have a valid Illinois registration or you're driving illegally.

To register a new-to-you vehicle, you'll need the title (or a bill of sale if the title hasn't transferred yet), proof of insurance, and your driver's license. First-time registrations include the vehicle use tax plus the registration fee. If the vehicle was previously registered in another state, you may need to provide an out-of-state registration document as well.

Frequently Asked Questions

Can I register my vehicle online if I just moved to Illinois?

If you're registering a vehicle for the first time in Illinois, you must do so in person or by mail—online renewal is only for vehicles already registered in the state. Bring your out-of-state registration, title, proof of insurance, and driver's license to a Secretary of State office, or mail the same documents with a check.

What if my vehicle has a lien on the title?

Vehicles with active liens must be registered in person or by mail, not online. The lienholder's name appears on the title, and the Secretary of State needs to verify the lien information. Bring the title and proof of insurance to a local office, or mail them with your registration form and payment.

Do I pay registration fees if my vehicle is registered to a business?

Commercial and business vehicles pay registration fees just like personal vehicles, based on weight class and age. Some commercial vehicles fall into different weight categories or may have additional fees depending on their use. Contact the Secretary of State to confirm the fee for a commercial vehicle's specific GVWR and classification.

What if I sell my vehicle before the registration expires?

Once you sell a vehicle, you're no longer responsible for its registration. Notify the Secretary of State that you've sold it so the registration transfers to the new owner. You don't receive a refund for the unused portion of your registration, but you won't owe any additional fees.

How do I know my vehicle's gross vehicle weight rating?

The GVWR is printed on a label on the inside of the driver's door jamb, usually on the edge of the door itself. It's also listed in your owner's manual. The label shows the GVWR in pounds and is separate from the actual weight of your vehicle—it's the maximum safe weight the vehicle can carry when fully loaded.
