The cost to register a standard passenger vehicle in Illinois for the first time is typically $151, but the final amount can vary significantly based on your vehicle's age, weight, and your county of residence. The total fee is composed of a base registration fee, license plate costs, and a title fee, with local county taxes often being the largest variable.
Here’s a breakdown of the standard fees for a passenger car (under 8,000 lbs):
| Fee Component | Standard Cost | Notes |
|---|
| Base Registration Fee | $101 | This is the state fee to register the vehicle for one year. |
| Vehicle License Plate Fee | $21 | Covers the cost of a new set of standard plates. |
| Title Fee | $155 | A one-time fee for a new title issued in your name. |
| Vehicle Tax (Most Counties) | Varies (e.g., $100+) | The largest variable. It's a percentage of the car's value, determined by a formula set by your county. |
| Plate Transfer Fee | $15 | If you are transferring plates from another vehicle you own. |
| Late Registration Penalty | $20 | Applied if you register the vehicle more than 30 days after purchase. |
The most significant cost factor is the vehicle tax assessed by your county. For a new car valued at $30,000 in a county with a standard tax rate, this tax could be around $300, making your total out-the-door cost closer to $450-$500. For older, less valuable cars, this tax is lower. All fees are paid to the Illinois Secretary of State (IL SOS). You can get a precise estimate using the official fee calculator on the IL SOS website by entering your vehicle identification number (VIN) and county.
