FL H0827

Online real estate listing platforms must display estimated ad valorem taxes for Florida residential properties based on the listing price and current millage rates, rather than showing the current owner's tax amount

Platforms must use either the Department of Revenue's published formula with current millage rates or the countywide aggregate average millage rate to calculate estimates, and include a disclaimer that actual taxes may vary

Current owner's ad valorem taxes cannot be displayed on listing platforms (except as historical information in limited circumstances) or included in printed listing materials

The Department of Revenue must publish tax calculation formulas and countywide aggregate millage rates on its website annually beginning December 15, 2026, with data provided by county property appraisers

Listing platforms and real estate licensees are protected from liability for the accuracy of estimated ad valorem taxes; effective date is February 1, 2027
