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 of current owners' ad valorem taxes for certain purposes, although it allows for their inclusion as historical tax information under specific conditions. Additionally, it requires that if estimated taxes are calculated using a tax estimator, the listing platform must display these estimates based on the property's listing price and current millage rates, along with a disclaimer regarding potential variations in millage rates and other tax considerations.

Furthermore, the bill stipulates that the Department of Revenue will develop and publish a formula for estimating ad valorem taxes, which listing platforms must use starting December 15, 2025. It also provides protection from liability for listing platforms and licensees regarding the accuracy of the estimated taxes when they comply with the new requirements. The act is set to take effect on January 1, 2026.
