How Illinois vehicle taxes and fees add up

Buying and registering a car in Illinois involves several separate costs. The state levies a 6.25% sales tax on the purchase price, and local jurisdictions can add more — the counties listed above average about 1.65%, for a combined rate near 7.90%. On top of the purchase price you pay one-time DMV fees to transfer the title and issue plates, plus an annual registration fee of about $151 to keep the vehicle legal on the road.

Insurance is the largest recurring cost for most drivers. Full coverage in Illinois averages about $1,390 per year, which works out to roughly $116 per month. Over a typical five-year ownership period that is about $6,950 in insurance alone.

Car insurance requirements in Illinois

Illinois is an at-fault (traditional liability) state, so the driver who causes an accident is generally responsible for the other party's losses. Drivers must carry at least $25,000 per person / $50,000 per accident in bodily injury liability and $20,000 in property damage liability. Uninsured/underinsured motorist coverage is $25,000/$50,000. Most drivers choose limits well above the minimum to protect their assets, and lenders typically require comprehensive and collision coverage while a loan is outstanding.

Illinois requires periodic vehicle inspections, so factor that into your maintenance schedule and budget.

Illinois EV and alternative-fuel incentives

VehCalc does not track a standing state-level EV purchase credit for Illinois in 2026 — several programs have wound down, and the federal EV tax credit ended September 30, 2025. Incentives change frequently, so verify current eligibility with your state energy office or the vehicle manufacturer before relying on any credit. Local utilities sometimes offer separate rebates for home charging or EV purchases.

How to lower your Illinois ownership costs

• Negotiate on the vehicle price, not the monthly payment — sales tax is charged on the price.
• Compare at least three insurance quotes; premiums for the same driver vary widely.
• Raise your credit score before financing to qualify for a lower APR.
• Check current EV and efficiency incentives that may apply to your vehicle.
• Keep registration and inspections current to avoid late fees and penalties.
