Provide for digital advertising tax

SB 192 would have imposed a 10% tax on digital advertising revenue generated within Montana by companies with worldwide annual digital advertising revenue exceeding $25 million. It directly affects large digital advertisers (like major tech or social media platforms) operating in Montana, taxing only the portion of their revenue derived from ads served to Montana users. The tax would be calculated using an apportionment method based on Montana ad revenue relative to total U.S. ad revenue, with returns due annually by April 15. All collected revenue would have been deposited into Montana's general fund, as specified in the bill's provisions. The bill died in committee in May 2025 and was not enacted.
