What You Need to Register a Vehicle in Illinois

Illinois registration requires you to submit proof of ownership, a completed process form, and proof of a passing emissions test (in most counties). The Secretary of State's office processes all registrations, but you can complete the transaction at a local Secretary of State facility, through the mail, or online for renewals. First-time registrations and transfers of ownership must be done in person or by mail.

The documents you'll need depend on whether you're registering a new vehicle, transferring ownership, or renewing an existing registration. A bill of sale, title certificate, proof of insurance, and a valid ID are standard requirements. If you're registering a vehicle purchased from a dealer, the dealer typically handles the title transfer paperwork, and you receive temporary registration to drive while the permanent registration processes.

Illinois charges registration fees based on vehicle type and weight. Passenger cars have a flat fee, while trucks and other vehicles may cost more. You'll also pay an emissions testing fee in counties that require it — currently Cook, DuPage, Kane, Lake, McHenry, and Will counties. The total cost varies, so check the Secretary of State website or call your local office for the exact amount for your vehicle.

How to Register a New Vehicle in Illinois

If you're registering a vehicle for the first time in Illinois, you'll need to visit a Secretary of State facility in person or submit documents by mail. Bring your title certificate (or a bill of sale if you don't have the title yet), proof of insurance, a completed process form (Form DSD 190), and a valid ID. If you purchased from a dealer, ask them for the title process paperwork — dealers often submit this on your behalf, but confirm before you leave the lot.

Before you register, you must pass an emissions test if you live in Cook, DuPage, Kane, Lake, McHenry, or Will County. Schedule the test at an approved emissions testing station and bring your test results to the Secretary of State office. The test costs around $30 to $40 and takes about 15 minutes. If your vehicle is brand new or was just purchased from a dealer, you may be exempt from the first-year emissions test — ask the testing station or the Secretary of State office.

At the Secretary of State office, you'll pay the registration fee and receive temporary registration when ready. Your permanent registration plate and sticker will arrive by mail within two to four weeks. You can drive legally with the temporary registration during this time, but do not remove it from your windshield until the permanent sticker arrives.

Renewing Your Illinois Registration Online

Illinois allows online renewal for most passenger vehicles if your registration is not expired and you have no outstanding violations or unpaid fees. Visit the Secretary of State's online renewal system, enter your vehicle information and driver's license number, and pay the renewal fee by credit or debit card. The process takes about 10 minutes, and your new sticker will arrive by mail within one to two weeks.

You cannot renew online if your vehicle requires an emissions test and you haven't passed it yet. In that case, you must renew in person or by mail after obtaining your emissions test results. Similarly, if your registration has been expired for more than a year, you'll need to renew in person at a Secretary of State office.

Keep your temporary registration sticker visible on your windshield until the permanent sticker arrives. Driving without a valid registration sticker is a violation and can result in a ticket.

Transferring Vehicle Ownership in Illinois

When you buy a used vehicle from a private seller, you must transfer the title into your name. The seller should provide you with the title certificate signed on the back. Complete the title transfer process (Form VSD 190) and submit it along with the signed title, proof of insurance, a valid ID, and the transfer fee to a Secretary of State office or by mail.

The Secretary of State will issue a new title in your name and send it by mail. You cannot legally register the vehicle until the title transfer is complete. If you're purchasing from a dealer, they typically handle the title transfer and provide you with temporary registration to drive while the paperwork processes.

If the seller cannot locate the title, you may be able to explore for a duplicate title through the Secretary of State. This process takes longer and may require additional documentation, so contact your local office for guidance.

Emissions Testing Requirements in Illinois

Six Illinois counties require emissions testing: Cook, DuPage, Kane, Lake, McHenry, and Will. If you live in one of these counties, your vehicle must pass an emissions test before you can register or renew your registration. The test checks your vehicle's exhaust emissions to may support it meets state air quality standards.

You can take your vehicle to any state-approved emissions testing station. The test costs between $30 and $40 and takes about 15 minutes. Bring your vehicle's registration or VIN, and the testing station will provide you with a test result form. If you pass, bring the results to the Secretary of State office when you register or renew. If you fail, you'll need to have your vehicle repaired and retested before you can complete registration.

New vehicles are typically exempt from emissions testing for the first model year. Vehicles that are 25 years old or older are also exempt. If you're unsure whether your vehicle requires testing, contact an emissions testing station or the Secretary of State office in your county.

Where to Register Your Vehicle in Illinois

The Secretary of State maintains dozens of facilities across Illinois where you can register your vehicle in person. Find the office nearest you by visiting the Secretary of State website and using the facility locator. Most offices are open Monday through Friday during standard business hours, though some have extended hours or Saturday appointments.

You can also mail your registration documents to the Secretary of State's central office in Springfield. Include all required documents, a check or money order for the registration fee, and a self-addressed stamped envelope. Processing by mail typically takes two to four weeks. The address and mailing instructions are available on the Secretary of State website.

For renewals only, the online system is the fastest option and requires no visit to an office. You'll receive your new sticker by mail within one to two weeks of completing the online transaction.

Registration Fees and What They Cover

Illinois registration fees vary based on vehicle type and weight. A standard passenger car registration costs one amount, while trucks, motorcycles, and other vehicle types have different fees. The Secretary of State website displays the exact fee for your vehicle type, or you can call your local office for a quote.

Your registration fee covers the cost of your registration plate and sticker for one year. If you live in a county that requires emissions testing, you'll pay an additional emissions testing fee (separate from the registration fee). Some vehicles may also be subject to a weight-based fee if they exceed certain thresholds.

Registration is valid for one year from the date it's issued. You'll receive a renewal notice by mail about 30 days before your registration expires. Renewing on time keeps you in compliance with state law and avoids late fees or penalties.

Frequently Asked Questions

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

No. Online renewal is only for existing Illinois registrations. If you're new to Illinois or registering a vehicle for the first time in the state, you must register in person at a Secretary of State office or by mail. After your first registration, you can renew online in future years.

What happens if my registration expires while I'm waiting for the new sticker?

If you renew before your registration expires, you can legally drive with your old sticker until the new one arrives by mail. The new sticker is valid from the date you renew, not from the date it arrives. Keep your renewal receipt in your vehicle as proof if you're stopped by police.

Do I need to retake an emissions test every year?

Yes, if you live in a county that requires emissions testing, your vehicle must pass the test every year before you can renew your registration. The only exceptions are new vehicles in their first model year and vehicles 25 years old or older.

What if I buy a vehicle out of state and move it to Illinois?

You have 30 days to register your out-of-state vehicle in Illinois. Bring your out-of-state title or bill of sale, proof of insurance, a valid ID, and proof of an emissions test (if required in your county) to a Secretary of State office. You'll pay the Illinois registration fee and receive a new Illinois title and registration.

Can I register a vehicle if the title has a lien on it?

Yes. If a lender holds a lien on your vehicle, the title will show the lender's name. You can still register the vehicle in Illinois. Bring the title showing the lien, proof of insurance, and your ID to the Secretary of State office. The registration will be issued in your name, and the lien information will be noted on your registration documents.
