Property tax bills are due Dec. 1, and those who didn’t receive a bill should contact the Hall County Tax Commissioner’s office, Tax Commissioner Keith Echols said. The office can be contacted at 770-531-6950 and is on the first floor of the new Hall County Government Center, 2875 Browns Bridge Road, Gainesville. Payment will be accepted without penalty until Dec. 3 since Dec. 1 falls on a Saturday, he added.
