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 estimated taxes are calculated using a tax estimator, the listing platform must provide a disclaimer regarding potential variations in millage rates and the exclusion of non-ad valorem assessments.

The bill also outlines requirements for the Department of Revenue and property appraisers, including the annual development and publication of a formula for estimating ad valorem taxes, starting December 15, 2025. It provides protection from liability for listing platforms and licensees regarding the accuracy of the estimated taxes when they comply with the new regulations. Furthermore, it prohibits the inclusion of current owners' ad valorem taxes in printed materials or social media posts related to the property. The act is set to take effect on January 1, 2026.
