IL SB2430

Extends Illinois' Hotel Operators' Occupation Tax (6% total - 5% base plus 1% additional) to short-term rentals beginning January 2026

Defines "short-term rental" as any residential dwelling rented wholly or partially for less than 30 continuous days, including houses, apartments, condos, and timeshares

Requires short-term rental unit providers to pay the tax unless the rental is booked through a short-term rental marketplace (like Airbnb or VRBO) that meets volume thresholds

Short-term rental marketplaces must collect and remit the tax if they have either $100,000 or more in cumulative gross receipts from Illinois rentals OR 200 or more separate rental transactions in Illinois

Adds definitions for "residential dwelling," "short-term rental," "short-term rental marketplace," and "short-term rental unit provider" to the Hotel Operators' Occupation Tax Act
