Illinois car registration costs depend on your vehicle type and weight

Illinois charges a base registration fee of $148 for most passenger cars, plus an additional $20 for the title certificate if you're registering a vehicle for the first time in the state. If you're renewing an existing registration, you pay only the $148 fee. The total cost is $148 for renewal or $168 for a new registration that includes the title.

However, your actual bill may be higher. Illinois adds a $10 fee to fund vehicle safety inspections, and some counties charge a local use tax that ranges from 0.25% to 2.25% of the vehicle's value. The state also charges a $5 fee for electronic registration processing. These extras mean most people pay somewhere between $163 and $200 for a standard renewal, depending on where they live and whether their county has a local use tax.

Trucks, motorcycles, and other vehicle types have different base fees. A motorcycle registration costs $48. Trucks are charged based on their gross vehicle weight rating (GVWR), starting at $148 for vehicles under 8,000 pounds and increasing for heavier trucks. Trailers and recreational vehicles have their own fee schedules.

When you need a title certificate versus just renewal

If you're registering a car in Illinois for the first time—because you just bought it, moved to the state, or are registering a vehicle you've owned but never registered—you need both a title certificate and a registration. The title costs $20 and the registration costs $148, for a total of $168. You'll also need to provide proof of ownership, such as a bill of sale or the title from your previous state.

If you already have an Illinois title and are straightforward renewing your registration because it's expiring, you pay only the $148 registration fee. Renewal notices are mailed to you about 30 days before your registration expires, and you can renew online, by mail, or in person at a Secretary of State office or authorized dealer.

The title certificate is a one-time cost. Once Illinois issues you a title, you don't pay that $20 fee again unless you need a duplicate title, which costs $10.

County use tax and where it applies

Illinois allows individual counties to charge a local use tax on vehicle registration. This tax is calculated as a percentage of your vehicle's fair market value, not the price you paid. The rate varies by county and ranges from 0.25% to 2.25%. Some counties do not charge a use tax at all.

For example, if you live in a county with a 1% use tax and your vehicle is valued at $15,000, you would owe $150 in use tax on top of the state fees. Cook County (which includes Chicago) charges a 1.25% use tax. DuPage County charges 0.5%. You can find your county's rate on the Illinois Secretary of State website or by calling your local county clerk's office.

The use tax is collected when you register or renew. If you move to a different county within Illinois, you may owe a different use tax rate when you renew, so it's worth checking before your renewal date.

How to pay and where to register

You have three ways to register a vehicle in Illinois: online through the Secretary of State website, by mail, or in person at a Secretary of State office or an authorized vehicle dealer. Online renewal is the fastest option and takes about 10 minutes. You'll need your current registration card, driver's license, and a payment method (credit card, debit card, or electronic check).

If you're registering a vehicle for the first time in Illinois, you cannot do it entirely online. You must go in person or mail in documents, because the Secretary of State needs to verify your proof of ownership and issue a title. Bring your bill of sale, the title from your previous state (if you have one), proof of residency, and a photo ID. Processing by mail typically takes 2 to 3 weeks.

In-person registration at a Secretary of State office or authorized dealer is the fastest way to complete a new registration. You'll walk out with temporary registration paperwork the same day, and your official registration card arrives by mail within 7 to 10 business days. Secretary of State offices are located throughout Illinois, and you can find the nearest one on their website.

Additional fees you might encounter

Beyond the base registration fee and county use tax, Illinois charges a $10 vehicle safety inspection fee on all registrations. This fee funds the state's vehicle safety inspection program. You don't pay this separately—it's included in your total registration bill.

If you need to register a vehicle that hasn't been registered in Illinois for more than two years, you may need to pass a safety inspection before registration is complete. This is a separate inspection performed at an authorized inspection station, and the cost varies but is typically $20 to $30. The inspection checks your brakes, lights, horn, windshield wipers, and other safety equipment.

If you register in person at a Secretary of State office or dealer, there may be a service fee of $1 to $5 depending on the location. Some authorized dealers charge a small convenience fee for handling your registration. Online registration through the Secretary of State website does not include an additional service fee.

Vanity plates and specialty registration options

Illinois offers vanity license plates, which let you choose a custom plate number instead of using a random assignment. A vanity plate costs an additional $50 on top of your registration fee. You can request a vanity plate when you register or renew online, by mail, or in person. The Secretary of State checks whether your requested plate is available before processing your order.

The state also offers specialty plates that support specific causes or organizations, such as military veteran plates, environmental plates, or university alumni plates. These plates typically cost between $25 and $50 extra per year, depending on the plate type. The additional fee goes to the organization or cause the plate supports.

If you want a vanity or specialty plate, add the extra cost to your base registration fee. For example, a vanity plate on a standard passenger car renewal would cost $148 (registration) plus $50 (vanity plate) for a total of $198, before any county use tax.

Frequently Asked Questions

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

No, you cannot complete a new registration entirely online. You must go in person or mail documents to the Secretary of State because they need to verify your proof of ownership and issue a title. However, you can renew an existing Illinois registration online.

What happens if I register my car after the expiration date?

Driving with an expired registration is illegal in Illinois. If you're caught, you can be fined. If your registration has expired, renew it as soon as possible. There is no additional late fee, but you cannot legally drive until your registration is current.

Do I have to pay the county use tax if I move to a county with a lower rate?

Yes, you pay the use tax rate of the county where you live when you renew. If you move to a county with a lower rate, you'll pay the lower rate at your next renewal. The use tax is based on your current residence, not where you registered the vehicle originally.

How much does a safety inspection cost if my car hasn't been registered in two years?

A safety inspection at an authorized inspection station typically costs $20 to $30. You'll need to pass this inspection before the Secretary of State will issue your registration. Find an authorized inspection station on the Illinois Secretary of State website.

What if I lose my registration card before it expires?

You can request a duplicate registration card from the Secretary of State for $5. You can order it online, by mail, or in person. A duplicate card takes about 7 to 10 business days to arrive by mail.
