The bill amends section 689.261 of the Florida Statutes to enhance the disclosure of estimated ad valorem taxes for residential properties listed on public-facing online platforms. It introduces definitions for "listing platform" and "property," and mandates that listings must include estimated ad valorem taxes. The current owner's ad valorem taxes are prohibited from being displayed or used for certain calculations, although they may be included as part of historical tax information under specific conditions. The bill also outlines requirements for listing platforms, the Department of Revenue, and property appraisers, including the development of a formula for estimating taxes that must be published annually on the Department's website.

Additionally, the bill provides protection from liability for listing platforms and licensees regarding the accuracy of estimated ad valorem taxes when they comply with the new regulations. It specifies that the current owner's ad valorem taxes cannot be included in printed materials or social media posts related to the property. The Department of Revenue is tasked with collecting necessary information from property appraisers to develop the tax estimation formula, which will be made publicly available starting December 15, 2025. The act is set to take effect on January 1, 2026.
