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 property listings must include estimated ad valorem taxes. The bill prohibits the use of the current owner's ad valorem assessment or taxes for calculating these estimates under certain conditions and requires listing platforms to use specified methods for calculating and displaying estimated taxes. Additionally, it mandates that listing platforms provide links to county property appraisers' homepages and tax estimators, while also ensuring that previous years' ad valorem taxes are not displayed as part of historical tax information.

Furthermore, the bill provides immunity for inaccuracies in estimated ad valorem taxes listed on these platforms and prohibits the inclusion of current owners' ad valorem taxes in printed materials. The Department of Revenue is tasked with developing a formula for calculating estimated ad valorem taxes and must publish this formula and the countywide aggregate average millage rate annually on its website. The bill is set to take effect on February 1, 2027.
