This 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 any property visible on such platforms must include estimated ad valorem taxes. The bill prohibits the display or use of current owners' ad valorem taxes for these estimates, although it allows for their inclusion as historical tax information under specific conditions. Additionally, if a tax estimator or buyer payment calculator is used, the listing platform must calculate and display the estimated taxes based on the listing price and current millage rates, accompanied by a disclaimer regarding potential variations in millage rates and other tax considerations.

Furthermore, the bill outlines requirements for listing platforms, the Department of Revenue, and property appraisers, while providing liability protection for platforms that comply with the new regulations. It also prohibits the inclusion of current owners' ad valorem taxes in printed materials or social media posts related to property listings. The Department of Revenue is tasked with developing an annual formula for estimating ad valorem taxes and must publish this information on its website starting December 15, 2025. The act is set to take effect on January 1, 2026.
