Flanked by business and real estate leaders, Crist put his name to HB 521. The bill lowers the burden of proof for owners who dispute property tax assessments to a preponderance of the evidence – a lower standard than the clear and convincing threshold they now must meet to overturn a property appraiser’s estimate.

Local governments had successfully scuttled earlier efforts to lower the standard. In the just-signed version, property appraisers still enjoy the presumption that their estimates are correct, but the legislative analysts say the bill will cost local governments $157 million during the current fiscal year, increasing to $693 million a year by 2013.
