Interstate Commerce Simplification Act of 2024

This bill amends an existing law (Public Law 86-272) to clarify the definition of "solicitation of orders" for businesses operating across state lines. It adds a new provision stating that any business activity facilitating order solicitation - such as online sales tools or marketing efforts - counts as "solicitation," even if the activity has other business purposes. This change directly affects businesses engaged in interstate commerce, particularly those selling goods or services remotely. The amendment aims to reduce legal ambiguity about when states can tax out-of-state sellers, without creating new tax rules or altering existing obligations.
