Illinois registration costs depend on your vehicle type and weight

Illinois charges a base registration fee of $101 for most passenger cars, plus an additional fee based on the vehicle's declared value. The value-based fee ranges from $20 to $300 depending on what your car is worth. For a typical used sedan worth $10,000 to $15,000, you can expect to pay between $150 and $200 total for a one-year registration.

The state also charges a $10 Leaking Underground Storage Tank (LUST) fee on all registrations. If your vehicle is over 8,000 pounds, the base fee increases — trucks and heavier vehicles pay $151 instead of $101. Specialty plates, vanity plates, or environmental plates add $25 to $50 on top of the standard fee.

Registration is valid for one year from the month you purchase it, and you renew it annually. The Secretary of State's office handles all registrations, but you can complete the transaction at any of Illinois's 159 Driver Services facilities or through an authorized vehicle dealer.

How the value-based fee is calculated

Illinois uses your vehicle's declared value to determine part of your registration cost. You report this value when you register, and the state uses it to calculate a sliding-scale fee. A car worth $5,000 or less pays a $20 value fee; a car worth $5,001 to $10,000 pays $50; a car worth $10,001 to $20,000 pays $100; and so on up to $300 for vehicles valued over $40,000.

The value you declare should match the actual market value of your vehicle, not the price you paid or what you owe on a loan. If you're unsure, you can use resources like Kelley Blue Book or NADA Guides to estimate your car's current value. The Secretary of State's office may request documentation if your declared value seems inconsistent with the vehicle's age and condition.

What documents you need to register

To register a vehicle in Illinois, bring your title or proof of ownership, a completed process for Vehicle Registration (Form VSD 190), proof of insurance, and a valid ID. If you're registering a used car you just purchased, you'll also need the bill of sale or purchase agreement showing the transaction date and price.

For vehicles financed through a loan, your lender's name will appear on the title as lienholder. You don't need the lender's permission to register, but the title document itself must be present. If you're registering a vehicle titled in another state, bring that out-of-state title along with your Illinois documents.

Proof of insurance in Illinois is mandatory before registration. Your insurance company will provide a declarations page or ID card showing your policy number and coverage dates. The registration cannot be issued without this proof.

Where to register and how long it takes

You can register at any of Illinois's 159 Driver Services facilities, which are located throughout the state. The Secretary of State's website lists all locations with hours and wait times. Most facilities operate Monday through Friday during business hours, with some offering limited Saturday service.

In-person registration typically takes 15 to 30 minutes once you're called, though wait times at busy locations can add an hour or more. If you register through an authorized vehicle dealer at the time of purchase, the dealer often handles the paperwork and you receive temporary plates when ready while your permanent registration processes.

Processing time after you submit your process is usually five to seven business days. Your registration certificate and license plates will be mailed to the address you provide. If you need plates when ready, some Driver Services facilities can issue temporary plates on the spot for an additional $5 fee.

Renewing your registration and late fees

Illinois sends renewal notices 30 days before your registration expires. You can renew online through the Secretary of State's website, by mail, or in person at a Driver Services facility. Online renewal is the fastest option and takes about five minutes; your new registration certificate arrives by mail within a week.

If you renew by mail, send your renewal notice with payment to the address listed on the form. If you renew in person, bring your current registration certificate and proof of insurance. The renewal fee is the same as the initial registration fee — $101 base plus your vehicle's value-based fee.

If your registration expires and you don't renew, driving with expired plates is illegal in Illinois. Late renewal carries a penalty of $50 plus your standard renewal fee. If your registration has been expired for more than 90 days, you may need to re-register as if it were a new vehicle rather than straightforward renewing.

Additional fees and special circumstances

If you change your address, you can update it online or at a Driver Services facility for no additional charge. If you need to replace lost or damaged plates, the fee is $15 per plate. Transferring registration to a new owner when you sell your vehicle requires the new owner to register it in their name; you don't transfer an existing registration.

Vehicles registered as commercial or for-hire (taxis, rideshare, delivery) pay higher registration fees — typically $301 base plus value fees. Vehicles registered as antiques or classics (25 years or older) pay a flat $50 registration fee instead of the standard structure, though they have restrictions on how often they can be driven.

If you register a vehicle with a salvage title (rebuilt after a total loss), the registration fee is the same, but you'll need an inspection certificate from an authorized Illinois inspection station before registration can be issued. This inspection costs $50 to $75 and verifies the vehicle is safe to drive.

Frequently Asked Questions

Can I register my car online in Illinois?

You can renew an existing registration online through the Secretary of State's website, but you cannot complete an initial registration online. New registrations and transfers require an in-person visit to a Driver Services facility or registration through an authorized dealer. Online renewal takes about five minutes and your certificate arrives by mail within a week.

What if I buy a car from a private seller instead of a dealer?

You'll need the signed title from the seller, a bill of sale showing the purchase price and date, proof of insurance, and your ID. Take these documents to a Driver Services facility to register the vehicle in your name. You'll pay the standard registration fee based on your car's value. Temporary plates are available for $5 if you need to drive before your permanent plates arrive.

Do I have to register my car in Illinois if I just moved here?

Yes. Illinois law requires you to register any vehicle you own within 30 days of establishing residency. If you move to Illinois with an out-of-state registration, you must register it with the Secretary of State. Driving with an out-of-state plate after 30 days is illegal, even if your out-of-state registration is still valid.

What happens if I register my car for less than its actual value?

The Secretary of State's office may request documentation if your declared value seems inconsistent with the vehicle's age and condition. Intentionally undervaluing a vehicle to avoid fees is considered fraud. If discovered, you may be required to pay back fees plus penalties. It's best to declare the actual market value of your vehicle.

Can I get a refund if I sell my car before my registration expires?

No. Illinois does not refund registration fees for partial-year registrations. Once you've paid for a one-year registration, that fee is not refundable even if you sell the vehicle after a few months. The new owner will need to register the vehicle in their own name and pay their own registration fee.
