This proposal authorizes a new homestead exemption from ad valorem taxes for municipal purposes in an amount equal to the amount by which the current year assessed value of a homestead exceeds the adjusted base year value of such homestead. This exemption would only apply to persons residing in a municipal corporation that is located in more than one county, that levies a sales tax for the purposes of a metropolitan area system of public transportation, and that has within its boundaries an independent school system. It enacts Code Section 48-5-44.1 of the Official Code of Georgia Annotated. If approved by a majority of the voters, the Act becomes effective on January 1, 2019, and applies to all tax years beginning on or after that date.
