Overview
If your address falls in the Chicago metro area (Cook, DuPage, and Lake counties in full, plus zip-code-defined parts of Kane, Kendall, McHenry, and Will) or the Metro-East St. Louis area (parts of Madison, Monroe, and St. Clair), you'll also need a passing emissions test before the system lets you renew - required every two years, and the mandatory test itself is free. Renew online, by mail, or in person; online is fastest and gives instant confirmation.

Illinois renewal cost FAQ
How much does it cost to renew registration in Illinois?
$151 for a standard passenger vehicle, $41 for a motorcycle - flat statewide. Add $100 if it's electric, or $13/$7 a year for a vanity/personalized plate. Renewing more than 30 days late adds a flat $20 penalty.
Which counties require an emissions test to renew?
The Chicago metro area - all of Cook, DuPage, and Lake counties, plus zip-code-defined parts of Kane, Kendall, McHenry, and Will - and the Metro-East St. Louis area, covering parts of Madison, Monroe, and St. Clair counties. The mandatory biennial test is free; a voluntary out-of-cycle retest runs about $20.
What happens if I let my registration lapse for months?
You can still renew normally - Illinois doesn't escalate the late fee past the flat $20 - but driving on an expired sticker risks a ticket, and if you're in an emissions county you'll need a current passing test on file before the system processes the renewal.
Can I renew entirely online?
Yes, at ilsos.gov, using your plate number and other identifying information. It's available 24/7, gives instant confirmation, and the sticker typically arrives by mail within about a week to ten days.
Does the emissions test cost anything if my car fails?
The scheduled biennial test itself is free regardless of outcome. If your vehicle fails, Illinois EPA outlines a repair-and-retest process, and low-income vehicle owners may qualify for a waiver if repair costs exceed a set threshold.
