The Fulton County assessors office will mail about 345,000 assessment notices on June 15, telling property owners their tax values and how much they can expect to pay. The notices start the clock on the 45-day appeal deadline.

They’re going out a month later than last year. Chief Appraiser David Fitzgibbon cited staff vacancies and a need for quality control and editing. Two years ago there was a disastrous chain of events after the office sent overblown estimates to about 136,000 Atlanta property owners, attributed to a computer glitch and careless staff.
