Illinois Short-Term Rental Laws (2026)

Illinois short-term rental compliance combines a statewide hotel-tax framework with city-specific licensing, registration, zoning, and operating rules. A property that can operate in Chicago or Rockford may face different requirements - or a prohibition - in another municipality.

This 2026 guide uses current Illinois Department of Revenue and municipal sources. Always verify the exact property address with state and local authorities before advertising or accepting a reservation.

Illinois Short-Term Rental Laws - Quick Answer

State tax applies: Illinois treats qualifying short-term rentals as hotels for Hotel Operators’ Occupation Tax purposes when at least one room is rented for less than 30 consecutive days and the accommodation is reserved in advance.
Register with IDOR: Operators subject to Hotel Operators’ Occupation Tax register with the Illinois Department of Revenue and generally file Form RHM-1.
Local rules control operation: Licensing, zoning, registration, caps, and bans vary by municipality.
Chicago has two paths: A unit may require shared-housing registration or a vacation-rental business license, depending on how it is operated.
Naperville prohibits short-term residential rentals: It does not operate the permit system described in the former version of this article.

What Illinois calls a short-term rental

The Illinois Department of Revenue defines a short-term rental as an owner-occupied, tenant-occupied, or non-owner-occupied dwelling in Illinois - including an apartment, house, cottage, or condominium - where at least one room is rented for less than 30 consecutive days and all accommodations are reserved in advance. A dwelling rented as a single unit is treated as one room for this definition.

IDOR’s Hotel Operators’ Occupation Tax applies to persons in the business of renting rooms to the public as living quarters for periods of less than 30 days. A binding right to occupy for at least 30 consecutive days may qualify the guest as a permanent resident, but early termination can make the earlier occupancy taxable. Confirm the contract facts with IDOR rather than relying only on the number of nights actually stayed.

Rate, registration, and returns

The state Hotel Operators’ Occupation Tax rate is 6% of 94% of gross receipts - an effective state rate of 5.64% before Chicago-area and local hotel taxes. Illinois does not apply the ordinary 6.25% sales-tax rate to the room charge as the former article claimed.

Operators register through MyTax Illinois or Form REG-1 and must list their Illinois properties. IDOR generally requires Form RHM-1. Monthly returns are due by the last day of the following month unless IDOR assigns quarterly or annual filing. Keep the registration certificate and records supporting receipts and deductions.

Hosting platforms in 2026

Hosting platforms for Illinois short-term rentals entered the Hotel Operators’ Occupation Tax framework on July 1, 2025 when they met the re-renter definition. Effective July 1, 2026, Illinois revised the marketplace-facilitator and re-renter rules. A platform may be responsible when it meets the statutory role and threshold, but hosts should not assume that every state, Chicago-area, or local tax is covered. Confirm the platform’s collection statement and the operator’s remaining IDOR and municipal filing duties.

Shared housing registration versus vacation-rental licensing

Chicago does not use one generic “short-term rental license.” Its code distinguishes shared housing units from licensed vacation rentals. Determine the correct category with the Department of Business Affairs and Consumer Protection before listing.

A shared housing host must register each unit, receive a unique registration number, and include that number in advertisements, platform listings, rental agreements, and bookings. Advertising or booking while the registration is pending is prohibited. Registration includes zoning review, review of the city’s prohibited-building list, and review of restricted residential zones. Registration is reviewed annually and is not transferable.

A property operated as a vacation rental follows the regulated-business-license provisions in Chicago Municipal Code Section 4-6-300. Building limits apply to vacation rentals and shared housing units in combination. The code generally limits the combination to no more than six units or 25% of the dwelling units in a building, whichever is less, unless a lawful adjustment applies.

Chicago also maintains a prohibited-building list, and individual precincts can become Restricted Residential Zones that prohibit new or additional shared housing units or vacation rentals. Check the current address lists before relying on an existing registration nearby.

Chicago tax

Chicago Municipal Code Section 3-24-030 imposes three city components on a vacation rental or shared housing unit:

4.5% Chicago Hotel Accommodations Tax;
4% vacation-rental/shared-housing surcharge; and
2% additional vacation-rental/shared-housing surcharge.

Those Chapter 3-24 components total 10.5% of the gross rental charge. They are only the Chicago municipal portion. IDOR also administers the Illinois state Hotel Operators’ Occupation Tax and Chicago-area taxes, including the Illinois Sports Facilities, Metropolitan Pier and Exposition Authority, and Chicago Municipal Hotel taxes. Use IDOR’s current rate table and city guidance for the full stack rather than adding a generic sales-tax percentage.

Naperville Short-Term Rentals Are Prohibited

Naperville Ordinance No. 20-087, effective September 1, 2020, makes it unlawful to operate, use, offer for rent, or advertise property in Naperville as a short-term residential rental, subject to the ordinance’s narrow post-closing leaseback exception. The ordinance defines the prohibited use as a residential structure offered for 30 consecutive days or less and excludes hotels, bed-and-breakfast establishments, and boarding facilities regulated under other provisions.

Naperville’s official guidance lists a $1,000-per-day fine and a $2,500-per-day fine for a subsequent violation within 12 months. The former article incorrectly described a Naperville permit and inspection program and a 5% short-term-rental tax. Hosts should treat Naperville as prohibited unless the city confirms that a different regulated accommodation category applies.

Rockford Short-Term Rental Rules

Rockford maintains a Rental/Short-Term Rental Registry and links its Short-Term Rental Ordinance from the city registration page. Register the property and verify zoning, inspection, safety, local-contact, and renewal requirements through the city’s registry before listing.

Rockford’s official tax page lists two local hotel/motel taxes: a 1% Redevelopment Fund Tax and a 5% Tourism/Hotel-Motel Tax. The local total is 6%, not the 7% stated in the former article. Returns and payments are due monthly by the last day of the month following the reporting month. State hotel tax remains separate.

Aurora Rental and Hotel-Tax Rules

Aurora’s official residential-property registration form identifies short-term rentals such as Airbnb within its non-owner-occupied rental registration process. The city’s materials require non-owner-occupied and multi-unit rental properties to register in the Rental Licensing Program and describe annual licensing and inspection duties. Because Aurora’s official materials do not present a standalone, universally applicable STR permit, confirm the property type, zoning, occupancy, and licensing path directly with Property Standards.

Aurora’s official Hotel Occupancy Tax page lists a 3% city hotel occupancy tax and requires a tax-collector certificate of registration for providers of covered accommodations. The former article’s 5% Aurora rate was unsupported and has been removed.

Illinois Host Compliance Checklist

Confirm the municipality and zoning district. Check municipal boundaries, county rules, building restrictions, condominium rules, and homeowners association restrictions.
Determine whether the use is allowed. A nearby city’s permit system does not override a local ban such as Naperville’s.
Classify the accommodation correctly. In Chicago, determine whether the unit is shared housing, a vacation rental, or another licensed accommodation.
Complete local registration or licensing before advertising. Include the required registration or license number in listings.
Register for Illinois hotel tax. Obtain the IDOR certificate and calendar Form RHM-1 deadlines.
Map taxes by address and booking channel. Separate state, Chicago-area, city, county, and platform-remitted amounts.
Verify building and safety rules. Confirm occupancy, smoke and carbon-monoxide alarms, exits, insurance, local-contact, parking, and inspection requirements with the responsible city.
Track changes. Renew registrations and licenses and recheck local rules before changing ownership, management, occupancy, or booking platforms.

Common Illinois Compliance Mistakes

Calling the Illinois room tax a 6.25% sales tax instead of using the Hotel Operators’ Occupation Tax framework.
Assuming a platform remits every state, Chicago-area, and municipal tax.
Calling every Chicago operation a “short-term rental license” without distinguishing shared housing from vacation rentals.
Assuming every Chicago host must reside in the building. Eligibility depends on the category, property, building, and applicable code restrictions.
Describing Naperville as a permit market when the city prohibits short-term residential rentals.
Using the former 5% Aurora and 7% Rockford local tax figures. Current official materials list 3% for Aurora and 1% plus 5% for Rockford.

Bottom Line

Illinois hosts need both state tax compliance and address-specific local authorization. Register with IDOR when required, then confirm that the municipality permits the use and complete every local license, registration, tax, zoning, and safety step before listing.
