When is the deadline to challenge my Milton property tax assessment?

Fulton County mails Milton property owners an annual assessment notice that states the exact appeal deadline for that year, since it is calculated from the mailing date rather than fixed on the calendar. That deadline applies whether you appeal informally with the assessor's office or go straight to a formal written appeal. Losing track of the notice is the most common reason homeowners miss their window entirely. Keep the envelope and check the date the moment it arrives.
