St. Simons Island attorney Jay Roberts, who is representing a group of taxpayers in three class action lawsuits against Glynn County, estimates the total amount of taxes at stake in the suit could be as high as $15 to 17 million. The suits alleges some local taxpayers, using the Scarlet Williams homestead exemption, were overtaxed because the tax commissioner at the time assigned their properties the wrong base year. The three lawsuits cover somewhere in the neighborhood of 6,500 to 9,000 taxpayers. The case started with the first class action filed in 2012 with two more filed in 2013 and 2014. Roberts said the amount is still increasing as the case drags on because the alleged problem has not been remedied and interest is accruing.
