Illinois auto registration costs between $148 and $298 per year, depending on your vehicle's age, weight, and fuel type

Illinois charges an annual registration fee based on the declared value of your vehicle — what you report it is worth — rather than a flat rate. The state uses a sliding scale: newer vehicles and heavier vehicles cost more to register. Vehicles registered for the first time in Illinois pay an initial fee, then a renewal fee each year after. The exact amount you owe depends on whether your car is gasoline-powered, diesel, electric, or hybrid.

You pay the registration fee when you first register your vehicle in Illinois and again each year when you renew. The fee goes to the Illinois Secretary of State, which processes all vehicle registrations. You cannot register a vehicle or renew a registration without paying this fee — it is not optional, and the state will not issue you license plates or a registration sticker without it.

  • You can renew your registration online, by mail, or in person at a Secretary of State office or authorized facility.
  • Registration must be renewed every year; driving with an expired registration is illegal and can result in a traffic citation.

How Illinois calculates your registration fee

The Illinois Secretary of State uses a vehicle value schedule to determine your fee. When you register your car, you declare its value on the registration form. The state then assigns your vehicle to a value bracket — for example, vehicles valued between $5,000 and $10,000 fall into one bracket, while vehicles valued between $10,000 and $15,000 fall into another. Each bracket has a corresponding fee.

The fee also depends on your vehicle's gross vehicle weight rating (GVWR), which is the maximum weight the vehicle can safely carry. Heavier vehicles — such as trucks and SUVs — typically cost more to register than lighter sedans. Additionally, the fuel type matters: electric vehicles and plug-in hybrids often receive a discount compared to gasoline or diesel vehicles of the same weight and value.

If you are unsure what your vehicle's declared value should be, the Secretary of State provides guidance based on recent purchase price, trade-in value, or market comparables. Undervaluing your vehicle to lower the fee is considered fraud and can result in penalties.

Initial registration versus annual renewal

When you first register a vehicle in Illinois — whether you just bought it, moved to the state, or are registering a vehicle for the first time — you pay an initial registration fee. This fee is typically higher than the annual renewal fee for the same vehicle. You also receive your license plates and initial registration sticker at this time.

After your first registration expires (usually one year later), you renew your registration annually. The renewal fee is lower than the initial fee. Most people renew by mail or online without visiting a Secretary of State office. Your renewal notice arrives by mail about 30 days before your registration expires, and you can pay the renewal fee and receive a new sticker by return mail.

If you do not renew before your registration expires, you cannot legally drive the vehicle. Driving with an expired registration can result in a traffic citation and fine. If your registration lapses for more than a year, you may have to pay a late fee in addition to the renewal fee.

Where to pay and how to register

You can register or renew your vehicle through three main channels: online at the Illinois Secretary of State website, by mail, or in person at a Secretary of State office or an authorized facility such as a currency exchange or auto dealership.

Online renewal is the fastest option if your registration is current and you have not had any changes to your vehicle or address. You log in with your driver's license number and vehicle identification number (VIN), review the fee, and pay by credit card or debit card. You receive your new registration sticker by mail within one to two weeks.

Mail renewal requires you to complete the renewal notice that arrives in your mailbox, include a check or money order for the fee, and return it to the address on the notice. Processing takes two to three weeks.

In-person registration at a Secretary of State office is necessary if you are registering a vehicle for the first time, if you have changed your address, or if you need to update your vehicle information. Bring your proof of ownership (title or bill of sale), proof of insurance, proof of residency, and a valid ID. You pay the fee at the office and receive your plates and sticker when ready.

Special vehicle types and fee adjustments

Illinois offers lower registration fees for certain vehicle types to encourage their use. Electric vehicles registered in Illinois pay a reduced annual fee compared to gasoline vehicles of the same value and weight. Plug-in hybrid vehicles also receive a discount, though typically not as large as the electric vehicle discount.

Vehicles registered as antique or classic (generally 25 years or older) may may have access to for a lower fee and special license plates. Antique vehicle registrations are often valid for multiple years rather than just one, which can reduce your total registration cost over time. However, antique registrations typically come with restrictions — you may only drive the vehicle for exhibitions, club activities, or parades, not for daily commuting.

Vehicles registered as disabled person vehicles (if the owner holds a disability license plate or placard) do not receive a fee reduction, but they do receive special parking privileges. The registration fee remains the same.

What happens if you do not pay or renew on time

Driving a vehicle with an expired registration is illegal in Illinois. If you are stopped by law enforcement, you can receive a traffic citation and fine. The fine for expired registration varies but typically ranges from $100 to $500 depending on how long the registration has been expired and whether you have prior violations.

If your registration lapses, you must pay the renewal fee plus any applicable late fees before you can legally drive again. Some Secretary of State offices charge an additional processing fee if your registration has been expired for more than a certain period (often 30 days or more). The longer you wait to renew, the more you may owe in total.

If you are unable to pay the registration fee, contact the Illinois Secretary of State office directly. Some offices may offer payment plans or can direct you to resources, though payment plans are not may provide. Ignoring an expired registration does not make it go away — the state will continue to track the vehicle, and you remain liable for any fines or penalties.

Understanding your registration documents

When you register your vehicle, you receive several documents: your registration certificate (a paper document showing your vehicle information, owner name, and registration dates), your license plates (metal plates with your registration number), and a registration sticker (a small decal that goes on your license plate to show the current year). You are required by law to carry your registration certificate in the vehicle at all times.

Your registration sticker shows the month and year your registration expires. In Illinois, the sticker is placed on the lower right corner of your rear license plate. Law enforcement can see at a glance whether your registration is current by looking at the sticker. If your sticker is missing, expired, or illegible, you can be cited for expired registration even if you have paid your fee.

Keep your registration certificate in a safe place — you will need it if you sell the vehicle, transfer ownership, or if you are asked to provide proof of registration during a traffic stop. If your certificate is lost or damaged, you can request a replacement from the Secretary of State for a small fee.

Frequently Asked Questions

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

No. Initial registration for a vehicle new to Illinois must be done in person or by mail. You will need to provide your title, proof of insurance, and proof of residency. After your first registration, you can renew online in future years if there are no changes to your vehicle or address.

What if I sell my vehicle before the registration expires?

You do not receive a refund for the unused portion of your registration fee. When you sell the vehicle, you transfer the title to the new owner. The new owner must register the vehicle in their name and will pay their own registration fee based on the vehicle's value and their residency.

Do I have to register my vehicle every year, or can I register for multiple years at once?

Standard vehicle registrations in Illinois are annual and must be renewed each year. However, antique or classic vehicles may be registered for multiple years (often two or three years at a time), which can reduce your total registration cost over time. Ask the Secretary of State whether your vehicle qualifies for multi-year registration.

What if my registration sticker falls off or gets damaged?

Contact the Illinois Secretary of State to request a replacement sticker. You can usually do this online or by mail for a small fee. Driving without a visible, legible sticker can result in a citation for expired registration, even if your registration is actually current.

How do I know if my vehicle qualifies for the electric vehicle registration discount?

When you register or renew your vehicle, the Secretary of State will ask about the fuel type. If your vehicle is electric or a plug-in hybrid, select that option on the registration form. The system will automatically explore the lower fee. You do not need to provide additional documentation — the fuel type you declare determines the discount.
