Car Rental Business Regulations in Illinois

Illinois requirements at a glance

What licenses do you need to rent cars in Illinois?

Register the business with the Illinois Department of Revenue before renting a single vehicle, register the fleet with the Secretary of State, and register separately with the Chicago Department of Finance if you operate in the city.

Tax registration comes first

Registration with the Department of Revenue must be complete before you make any purchases, sales or hires. Registering through MyTax Illinois takes one to two business days. The paper route, Form REG-1, takes four to six weeks, which is long enough to delay a launch.

Fleet registration with the Secretary of State

Illinois has no rental-specific plate class. What it does have is a fleet registration program for first-division vehicles: you file a signed application under penalty of perjury, pay the standard registration fees, enter into a contract with the Secretary of State, and demonstrate electronic data interchange capability. The Secretary may impose further qualifications based on fleet size and your registration history.

Chicago is a separate registration

Operating in Chicago means registering with the Chicago Department of Finance for two city taxes covered below. A state registration does not cover them, and the city expects businesses renting vehicles on a daily or weekly basis to register.

What is the Illinois automobile renting tax?

Five percent of gross receipts under the Automobile Renting Occupation and Use Tax Act, on any transfer of possession for one year or less. The 5 percent occupation tax is your liability as the rentor; a matching 5 percent use tax is the renter's liability, which you collect and state separately on the invoice.

What falls outside the taxable base

Three charges are excluded when separately itemized: additional insurance coverage, refueling the vehicle, and a waiver. That is a direct argument for itemizing your rental agreement rather than quoting one bundled figure, because a bundled total is taxed in full.

Why sales tax does not apply to your rental receipts

Illinois brought leases into the Retailers' Occupation Tax on 1 January 2025, but expressly carved out motor vehicles required to be titled or registered with the state. The Department of Revenue confirmed the position again in April 2026: for registered vehicles, dealers owe retailers' occupation tax, lessors owe use tax, and lessees owe neither. In practice, sales tax is a purchase-side cost when you buy the vehicle, not a charge on the rental.

The vehicles covered are broader than most operators expect: first-division vehicles, pickup trucks and SUVs, motorcycles, qualifying motor homes, and passenger vans seating 7 to 16. Peer-to-peer car sharing is excluded where retailers' occupation tax or use tax was paid on the vehicle at purchase or on entry into Illinois.

What does a Chicago operator pay on top?

Three more layers. The MPEA tax at 6 percent across Cook County, the Chicago Personal Property Lease Transaction Tax at 15 percent, and the Chicago Motor Vehicle Lessor Tax at 50 cents per rental period.

The MPEA tax applies across Cook County

The Metropolitan Pier and Exposition Authority levies 6 percent of gross receipts on automobile renting anywhere in Cook County, in force since October 1992. It is administered and collected by the Illinois Department of Revenue rather than by the authority, so it files with your state return. Taxicab and livery rentals are excluded.

Worth noting: the MPEA airport departure tax is a different charge entirely, applying to taxis, livery, buses and scheduled service. Rental cars are not a taxable category under it.

The Chicago lease transaction tax is the one that moved

Chicago's Personal Property Lease Transaction Tax rose from 9 percent to 11 percent on 1 January 2025, and to 15 percent on 1 January 2026. If your pricing was set before 2025 it is now four percentage points behind. The city's own rate page has not been updated to reflect the current figure, so confirm with the Department of Finance rather than the website.

The lessor tax moved the other way

The Chicago Motor Vehicle Lessor Tax fell from $2.75 to $0.50 per vehicle per rental period on 1 January 2026. It is small, but it is a per-rental charge rather than a percentage, so it weighs most on short, cheap rentals. Government entities are exempt, as are taxpayers subject to the ground transportation tax.

Renting outside the city does not put you outside the city tax

This is the trap. Chicago applies the lease transaction tax to the privilege of using leased property in the city, not only to rentals that start there. For rental locations within three miles of the city border, excluding O'Hare, the Department of Finance will presume on audit that Chicago residents use the vehicle in Chicago and non-residents do not. There is an exemption where the vehicle is used more than half the time outside Chicago, but the burden of proof sits with you and it must be in writing. A 25 percent safe harbor is available instead: treat a quarter of rental charges to Chicago residents as taxable and skip the detailed record-keeping.

What does the Chicago tax stack cost on a real rental?

On a $250 rental charge, with insurance, fuel and waiver charges itemized separately and therefore outside the base:

The same vehicle at the same rate costs a Chicago renter $53 more in tax than a Springfield renter. If you quote a single statewide rate across both markets, you are absorbing that difference yourself.

One caveat on the arithmetic. Whether Chicago computes its 15 percent on the bare rental charge or on the charge plus the state and MPEA taxes is not settled in published guidance. The figures above compute each tax on the bare $250. Confirm the ordering with the Department of Finance before building it into a pricing engine. The Springfield figure also assumes no local municipal or county tax, which is worth checking by address.

How do you file and pay Illinois rental tax?

Monthly, on Form ART-1, due by the 20th day of the month following the reporting period. A return is required even in a month with no rental receipts.

Operators with more than one location also file Form ART-2, the multiple site form, which reports receipts by site so the correct local rate applies to each. That matters because municipalities and counties may each impose up to 1 percent, and many have. The Department of Revenue publishes no list of which ones, so rates have to be looked up by address in the MyTax Illinois Tax Rate Finder.

If the 20th falls on a weekend or holiday, the deadline moves to the next business day.

What insurance is required for rental vehicles in Illinois?

Illinois requires minimum liability of 25/50/20: $25,000 bodily injury per person, $50,000 per crash, and $20,000 property damage. Uninsured motorist coverage is required at the same 25/50 bodily injury limits.

Those limits have applied since January 2015. Underinsured motorist coverage is required only where your uninsured motorist coverage exceeds the statutory minimum, so a bare-minimum policy carries no separate underinsured obligation.

Treat 25/50/20 as a legal floor rather than adequate protection. A $20,000 property damage limit is below the replacement cost of most vehicles in a rental fleet. Confirm appropriate commercial coverage with a broker who works with rental operators.

What must an Illinois rental agreement disclose?

Illinois regulates rental agreements through the Vehicle Code and a dedicated damage waiver act. You must inspect and verify the renter's licence before handing over the vehicle, provide an emergency assistance telephone number, and keep a record of every rental.

The renter or a designated driver must hold a valid licence from Illinois or their home jurisdiction. You must inspect the licence, including by electronic or digital means, and verify it is current, before renting. Motorcycle rentals require a current motorcycle operator's licence. You must provide an emergency telephone number to personnel capable of handling roadside assistance and customer service, and make the owner's manual accessible through customer service.

Advertised rental rates must include the entire amount except taxes, a mileage charge and airport concession charges, and you must supply an estimated total on request. Required fuel charges and required airport surcharges are prohibited outright. Optional insurance, accessories, alternative return location fees and actual refueling costs are all permitted.

Records must cover the vehicle registration number, the renter's name and address, and their licence number and place of issuance. Electronic records satisfy this, and they must be available for police inspection.

Damage waiver rules are strict and specific

A damage waiver may only be voided on nine enumerated grounds, including carrying persons or property for a charge, racing, criminal acts by the driver, and operation by a driver not permitted under the agreement. You need the renter's written agreement before selling a waiver at all.

The agreement must carry a notice that the waiver is optional and that the renter should review existing insurance first, in boldface type of at least 10 points, with a space for a signed acknowledgment. Advertising must show the daily waiver rate conspicuously and state that it is an optional additional charge: print ads at a minimum of 10-point type, television disclosures at one-third the size of the depiction of the rental cost, and radio an oral statement immediately after any mention of cost. Locations must post a sign or supply a pamphlet explaining the waiver. Illinois sets no cap on what you may charge.
