The Hall County Board of Commissioners denied a claim by Publix Supermarkets for a refund on property taxes paid from 2011 through 2013, a move that has been repeated by other counties across the region. Chief Tax Assessor Steve Watson said Publix is seeking the refunds based on a new methodology used to calculate how much vendor credits would reduce its inventory levels at six stores across Hall County. Inventory levels are one measure used to assess the value of commercial properties.
