Where to register and what documents you need

Vehicle registration in Illinois is handled by the Secretary of State's office through local branch locations and online. You can register a new vehicle, transfer ownership, or renew an existing registration at any of the 73 branch offices across the state, or you can complete most transactions online through the Secretary of State website.

Before you go to a branch or start an online registration, gather these documents: your vehicle's title (or proof of ownership if the title is being mailed), a completed process for Vehicle Registration (Form VSD 190), proof of a passing emissions test (required for most vehicles), proof of insurance, and a photo ID. If you're registering a vehicle purchased from a dealer, the dealer usually handles the initial paperwork and sends it to the Secretary of State on your behalf.

The cost of registration varies based on your vehicle's weight and type. A standard passenger car typically costs between $95 and $135 for a one-year registration, but the exact amount depends on the vehicle's gross weight rating. You can find the fee calculator on the Secretary of State website by entering your vehicle information.

Key Takeaways

  • Illinois vehicle registration is processed through the Secretary of State's 73 branch offices or online, and you must have your title, completed Form VSD 190, proof of insurance, and a passing emissions test.
  • Registration fees depend on your vehicle's weight and type, and you can calculate the exact cost on the Secretary of State website before you register.
  • New vehicles purchased from dealers are usually registered by the dealer, but you will receive the registration documents by mail within two to three weeks.
  • You can renew your registration online, by mail, or in person, and Illinois sends renewal notices 30 days before your current registration expires.

Registering a new vehicle you purchased privately

When you buy a vehicle from a private seller in Illinois, you become responsible for getting it registered. You must complete this within 30 days of purchase, or you risk a fine. Start by obtaining the title from the seller — it should be signed over to you, and the seller's name should be removed as the registered owner.

Take the signed title, your proof of insurance, and your photo ID to any Secretary of State branch office. Bring a completed process for Vehicle Registration (Form VSD 190), which you can fill out before you arrive or at the office. You will also need proof that the vehicle passed an emissions test within the past 30 days. Illinois requires emissions testing for most vehicles, though some older or specially equipped vehicles are exempt — the branch office can tell you if yours needs it.

The branch will process your registration on the spot, and you will receive your registration card and license plates when ready if you are registering in person. If you register online through the Secretary of State website, you will receive your registration documents by mail within five to seven business days.

Registering a vehicle purchased from a dealer

When you buy a vehicle from a licensed Illinois dealer, the dealer handles most of the registration work for you. Before you leave the dealership, the dealer will give you a temporary registration permit that is valid for 30 days while your permanent registration is being processed. This permit allows you to drive the vehicle legally during that time.

The dealer submits your registration paperwork to the Secretary of State on your behalf. You will receive your permanent registration card and license plates by mail within two to three weeks. During this waiting period, keep the temporary permit in your vehicle. If you do not receive your permanent registration within three weeks, contact the dealership to confirm they submitted the paperwork.

You are responsible for providing proof of insurance to the dealer before the sale is finalized. The dealer will not complete the registration without it, so have your insurance information ready before you sign the purchase agreement.

Online registration and renewal

The Secretary of State's online registration system allows you to renew an existing registration or register a vehicle without visiting a branch office. You can access the system through the Secretary of State website using your driver's license number and vehicle identification number (VIN).

Online registration works best for renewals, since you already have a registration on file. For new registrations of privately purchased vehicles, you will still need to visit a branch office in person to present your title and proof of ownership. However, you can start the process online and complete it at the office to save time.

When you renew online, you pay the registration fee by credit or debit card. Your new registration documents are mailed to you within five to seven business days. You can renew up to 90 days before your current registration expires, so you do not have to wait until the last moment.

Emissions testing requirements

Illinois requires an emissions test for most vehicles before registration or renewal. The test must be completed within 30 days before you register or renew. You can take your vehicle to any licensed emissions testing station in Illinois — the Secretary of State website has a list of stations by county.

The test costs between $25 and $35 and takes about 15 minutes. Your vehicle must pass the test to complete registration. If your vehicle fails, you have 30 days to make repairs and retest at no additional charge. Some vehicles are exempt from emissions testing, including vehicles that are 25 years old or older, diesel vehicles, and certain hybrid or electric vehicles.

When you pass the emissions test, you will receive a certificate or sticker showing the test date. Bring this proof to the Secretary of State branch office or upload it when you register online. If you register through a dealer, the dealer will handle the emissions test requirement as part of the registration process.

License plates and registration stickers

When you register a vehicle in Illinois for the first time, you receive a set of license plates and a registration sticker. The registration sticker goes on your license plate and shows the month and year your registration expires. You must display both the plates and the sticker on your vehicle at all times.

If you register in person at a branch office, you receive your plates and sticker when ready. If you register online or through a dealer, your plates and sticker are mailed to you. During the waiting period, use the temporary registration permit provided by the dealer or the branch office.

License plates in Illinois are valid for the life of the vehicle unless you request a replacement. You do not need new plates when you renew your registration — you only need a new registration sticker. If a plate is lost, stolen, or damaged, you can request a replacement at any branch office for a small fee.

What to do if you move or change your address

If you move to a different address in Illinois, you must notify the Secretary of State within 30 days. You can update your address online through the Secretary of State website, by mail, or in person at a branch office. Bring your current registration card and a photo ID if you update in person.

Updating your address does not require a new registration or new plates — it is a straightforward administrative change. The Secretary of State will mail any future registration documents to your new address. If you move out of Illinois, you will need to register your vehicle in your new state and surrender your Illinois registration.

Frequently Asked Questions

How long does it take to register a vehicle in Illinois?

If you register in person at a branch office, registration is processed when ready and you receive your plates and sticker the same day. If you register online or through a dealer, your documents are mailed within five to seven business days. Temporary registration permits are valid for 30 days while you wait for permanent documents.

Can I register a vehicle without an emissions test?

Most vehicles require an emissions test within 30 days before registration. Vehicles 25 years old or older, diesel vehicles, and certain electric or hybrid vehicles are exempt. Check the Secretary of State website or ask at a branch office whether your vehicle needs testing.

What if I buy a vehicle from out of state?

You must register the vehicle in Illinois within 30 days of moving it to the state. Bring the out-of-state title, proof of insurance, and a photo ID to a branch office. The branch will help you transfer the title to Illinois and complete registration. You will also need a passing emissions test.

Do I need to register a vehicle if I only drive it occasionally?

Yes. Any vehicle you own and drive on Illinois roads must be registered, regardless of how often you drive it. The only exception is a vehicle stored off-road that is not driven. If you store a vehicle for the winter or long-term, you can let the registration expire, but you cannot drive it on public roads without active registration.

What happens if I register late?

If you do not register within 30 days of purchase, you face a fine. The fine amount depends on how late the registration is. If you are pulled over while driving an unregistered vehicle, you can receive a ticket. Register as soon as possible after purchase to avoid penalties.
