All vehicles must be registered through the Illinois Secretary of State’s (SOS) office. If you have just moved to Illinois, you must register your vehicle within 30 days in person at the SOS office. Auto insurance must be purchased before registering the vehicle.
New resident registration
If you are new resident and wish to register you vehicle you must provide the following:
- A completed application for vehicle transaction form
- Evidence you live in Illinois
- Registration and title
- Description of vehicle, such as make, model, and year, VIN, and date of purchase
- Tax forms, which depend on whether you bought from a private seller or dealer
- Registration fee, which is $101
- Tax fees, which are based on the value of the car
As soon as you buy or receive a vehicle in Illinois, whether you have purchased it or inherited it, you have 20 days to register it. If you purchase it from a dealer, they send all of the documents to the SOS office. It is important to double check with the dealer to make sure everything is completed. If you bought your vehicle from a private seller, you must register the vehicle yourself, in person, at the local SOS office.

Military members who are not residents of Illinois must have auto insurance and proper registration on their vehicles from their home state. If this is not done, a law enforcement officer can pull you over and risk getting a fine.
Illinois does not require emissions testing to register a vehicle. However, vehicles are required to have regular emissions tests. You can do this by submitting your VIN to the Title and Registration Status Inquiry page, which will tell you if you need an emissions test.
If you have any more questions about this process, be sure to visit the Illinois CyberDrive SOS website.
