What Do You Need to Register a Car in Illinois?

Registering a vehicle in Illinois means working through the Illinois Secretary of State's office — not the DMV, as Illinois doesn't have a traditional DMV system. The process is similar to other states in its general shape, but the specific documents, fees, and steps depend on factors like where you bought the vehicle, whether it's new or used, and whether you're transferring a plate or getting a new one.

Here's how Illinois vehicle registration generally works and what most drivers will need to have ready.

The Core Documents You'll Typically Need

Illinois requires a standard set of documents for most registration transactions. While your exact situation may call for additional paperwork, these are the baseline items:

Proof of ownership This is the vehicle's title. If you bought the car from a private seller, you'll need the signed-over title in your name. If you bought from a dealership, the dealer typically handles the title application on your behalf. If you're registering a vehicle you've owned in another state, you'll need to transfer the out-of-state title to an Illinois title first.

Proof of Illinois insurance Illinois requires liability insurance to register a vehicle. You'll need to show proof of coverage that meets the state's minimum requirements. An insurance card or declaration page is usually acceptable.

Completed application form The standard form is the Secretary of State's Vehicle Registration / Title Application (Form VSD 190). Dealers often complete this for you. Private-party buyers typically fill it out themselves.

Payment for fees and taxes Registration fees in Illinois vary based on vehicle type, weight, and sometimes fuel type. You'll also owe Retailers' Occupation Tax (sales tax) if you purchased the vehicle — rates vary based on the county and municipality where you live, not where you bought it. Tax is calculated on the purchase price or fair market value.

Odometer disclosure For most vehicles under 10 years old, federal law requires a mileage disclosure at the point of sale. This is usually included on the title itself or on a separate disclosure form.

New vs. Used: How the Process Differs

🚗 Buying from a dealer is generally more streamlined. Illinois dealers are required to handle the title and registration paperwork on your behalf, and many collect the fees and taxes at closing. You typically receive temporary registration and wait for permanent plates or a renewal sticker.

Buying from a private seller puts more responsibility on you. You have 20 days from the purchase date to apply for a title and registration before late fees can apply. You'll take the signed title and other documents to a Secretary of State facility yourself.

Transferring from another state involves surrendering your out-of-state title and getting an Illinois title issued first — then completing registration. If the vehicle has a lien, the lienholder's involvement may be required.

Fees: What Shapes What You'll Pay

Illinois registration fees aren't flat across the board. Several factors affect the total:

Illinois also charges a private-party vehicle use tax instead of sales tax when buying from an individual — the rate depends on the purchase price. This is separate from the registration fee itself.

What About Plates?

If you're transferring plates from a vehicle you already own, the process is different from getting brand-new plates. Illinois allows plate transfers in many situations, which can affect your fees and what you need to bring. If you're getting new plates, standard passenger plates are issued by default unless you request specialty or personalized options.

Where to Register

Illinois Secretary of State facilities handle in-person registration. Some transactions — particularly renewals — can also be done online or by mail, but new title applications and out-of-state transfers typically require an in-person visit. Some currency exchanges and authorized agents around Illinois also process certain registration transactions.

Situations That Add Complexity

Certain circumstances require extra steps or documentation:

• Vehicles with liens: The lienholder may hold the title; you may need a release letter or the lienholder must be noted on the Illinois title
• Inherited vehicles: Requires estate or probate documentation
• Rebuilt or salvage titles: Additional inspection requirements may apply
• Commercial vehicles: Weight-based registration rules differ significantly from passenger vehicles
• Leased vehicles: The leasing company is typically the title owner; registration is handled differently

The Pieces That Depend on Your Situation

Illinois registration isn't complicated in concept, but the exact documents, fees, taxes, and steps you'll face depend on where in the state you live, where and how you bought the vehicle, what type of vehicle it is, and what its title history looks like. A straightforward private-party purchase of a passenger car is a different process than registering a truck with an out-of-state title and an active lien.
