What You Need to Do to Register a Car in Illinois
To register a car in Illinois, you submit documents to the Secretary of State's office — either in person at a Driver Services facility, by mail, or online through their website. You will need the vehicle's title, proof of ownership, a completed process form, and proof of a passing emissions test (for most vehicles). The process takes about two weeks by mail or same-day if you go in person, and costs between $150 and $300 depending on the vehicle's age and weight.
Illinois does not issue temporary registration stickers while you wait. You must have valid registration before you drive the vehicle legally on public roads, so plan to complete this before you need to use the car.
Key Takeaways
- You need the vehicle title, proof of ownership, a completed Form DSD 178 or 180, and an emissions test result to register in Illinois.
- New residents have 30 days from moving to Illinois to register an out-of-state vehicle; existing residents must register before driving.
- Most vehicles require a passing emissions test from an Illinois-certified testing station before registration is complete.
- Registration costs vary by vehicle weight and age, ranging from roughly $150 to $300, plus emissions test fees of $25 to $35.
- You can register online, by mail, or in person at a Driver Services facility; online is fastest for renewals, but new registrations often require in-person submission.
Documents You Must Bring or Submit
The Illinois Secretary of State requires a vehicle title showing your name as the owner. If you bought the car from a dealer, the title will arrive in the mail from the previous owner's lender or the state where the car was last registered. If you bought it privately, the seller must sign the title and give it to you before you can register it.
You also need proof of ownership — typically the bill of sale, purchase agreement, or dealer invoice showing your name and the vehicle identification number (VIN). Bring a government-issued photo ID and proof of your Illinois address, such as a utility bill, lease, or mortgage statement dated within 30 days of your process.
Complete Form DSD 178 (process for Vehicle Registration) if this is your first registration in Illinois, or Form DSD 180 (process for Vehicle Registration Renewal) if you are renewing. Both forms are available on the Secretary of State website or at any Driver Services facility.
The Emissions Test Requirement
Illinois requires an emissions test for most gasoline vehicles model year 1996 and newer, and diesel vehicles model year 2007 and newer. Vehicles registered in Cook County (Chicago) and the collar counties have stricter testing requirements than the rest of the state. Electric vehicles and vehicles model year 2025 and newer are exempt.
You must pass the test before you submit your registration. Find a certified testing station through the Illinois Environmental Protection Agency website — search by ZIP code to locate one near you. The test costs $25 to $35 and takes about 15 minutes. You will receive a certificate showing your VIN and test result; include this with your registration documents.
If your vehicle fails, you have 30 days to repair it and retest at no additional cost at the same station. After the repair, bring the new passing certificate with your registration process.
Registration by Mail, Online, or In Person
If you are renewing an existing Illinois registration, you can renew online through the Secretary of State's website using your driver's license number and vehicle registration number. Online renewal takes minutes and is the fastest option for renewals only.
For a new registration (first time registering a vehicle in Illinois), you typically must submit documents in person at a Driver Services facility or by mail. Mail submissions take two to three weeks; in-person visits are same-day. To register by mail, send your completed form, title, proof of ownership, emissions certificate, and a check or money order to the address listed on the Secretary of State website. Include a copy of your ID and proof of address.
To register in person, visit any Driver Services facility with all original documents. Bring the title, not a copy. Facilities are open Monday through Friday, 8 a.m. to 5 p.m., and some locations offer Saturday hours. Wait times vary; check the Secretary of State website for current wait times at your nearest location.
Registration Costs and Payment
Illinois registration fees are based on the vehicle's age and gross vehicle weight rating (GVWR). A passenger car typically costs $150 to $200 for the first registration and $150 to $180 for renewal, but the exact amount depends on the vehicle's weight. Trucks and SUVs with higher GVWRs cost more — sometimes $250 to $300 or higher.
You will also pay for the emissions test ($25 to $35) and any late fees if you register after your important date. If you register in person, you can pay by cash, check, debit card, or credit card. By mail, send a check or money order. Online renewals accept credit and debit cards only.
The Secretary of State website has a fee calculator where you enter your vehicle's VIN and it shows the exact registration cost for your car.
Timeline and When Registration Is Valid
Illinois registration is valid for one year from the date it is issued. Your registration sticker shows the expiration month and year. If you register in person, you receive your sticker and registration card when ready. If you register by mail, the sticker arrives within two to three weeks; do not drive the vehicle until it arrives.
New residents moving to Illinois from another state have 30 days to register their vehicle. After 30 days, driving an out-of-state registered vehicle is illegal. If you miss the important date, you may face fines and your vehicle could be impounded.
If you buy a vehicle from a dealer in Illinois, the dealer may handle the registration for you as part of the sale. Confirm this before you leave the lot. If you buy privately, you are responsible for registering within the required timeframe.
Special Situations: Salvage, Rebuilt, and Antique Vehicles
Salvage and rebuilt vehicles require additional inspection and documentation. A salvage title means the vehicle was declared a total loss by an insurance company; a rebuilt title means it was repaired after being declared a total loss. Both require an in-person inspection at a Driver Services facility before registration is issued. Bring the salvage or rebuilt title, proof of ownership, and proof of repairs.
Antique vehicles (25 years old or older) can be registered with an antique vehicle plate, which costs less than standard registration and does not require an emissions test. You must own the vehicle primarily for hobby or collection purposes, not for regular transportation. Use Form DSD 178 and note that it is an antique vehicle.
Frequently Asked Questions
Can I drive my car before I receive my registration sticker?
No. You must have valid registration before driving on public roads in Illinois. If you register in person, you receive your sticker when ready. If you register by mail, wait for the sticker to arrive before driving. Driving without registration can result in fines and vehicle impoundment.
What if my title is from another state?
You can register in Illinois with an out-of-state title. Bring the original title, proof of ownership, and your other required documents. The Secretary of State will process the out-of-state title and issue an Illinois title. This does not change the registration process or cost.
Do I need insurance before I register?
Illinois does not require proof of insurance to register a vehicle, but you must have liability insurance before you drive it on public roads. Insurance and registration are separate requirements. Confirm your insurance is active before you pick up your registered vehicle.
What happens if I register late?
Late registration incurs a penalty fee on top of the standard registration cost. The penalty increases the longer you wait. If your registration expires and you do not renew within a set period, your vehicle registration is suspended and you cannot legally drive the vehicle.
Can someone else register my car for me?
Yes, if you give them a signed power of attorney form (available on the Secretary of State website) and all required documents. The person registering on your behalf must bring the original title, your signed power of attorney, and their own ID. In-person registration requires the title in original form, so mail-in registration may be easier if someone else is handling it.
