If you own residential or investment property in Metro Atlanta, your Annual Notice of Assessment has either landed in your mailbox or is on its way. While it’s easy to stash that statement away with your utility bills, ignoring it could cost you thousands over the next few years.
Because each Metro Atlanta county operates on its own schedule, there is no single statewide deadline. Here is what you need to know about county-specific cutoffs, key deadlines, and how to protect your property’s value.
45 Days to Act: Key County Deadlines
Under Georgia law, homeowners have exactly 45 days from the date printed on their notice to submit an official appeal to the county Board of Tax Assessors. Missing this window means you forfeit your right to challenge your valuation until next year.
Crucial Rule: Your 45-day countdown begins on the Notice Date printed on the form—not the day you open your mail!
Why Filing an Appeal Is Worth the Effort
County tax assessors estimate property values en masse using regional market algorithms. These automated calculations frequently overlook property-specific flaws, delayed renovations, or hyper-local price fluctuations.
If your notice lists a market value higher than what your home would actually sell for on the open market, appealing can directly lower your annual property tax burden.
The Georgia “3-Year Freeze” Advantage
Winning an appeal does not just reduce your tax bill for a single year. Under O.C.G.A. § 48-5-299(c), an appeal resulting in a reduced valuation locks that lower assessed value for three consecutive tax years (the current year plus the next two). This provides a vital safeguard against rapid assessment spikes.
3 Steps to File Your Appeal
Filing an initial appeal with your local Board of Equalization (BOE) costs $0:
- Verify Your Notice Date: Locate the exact deadline printed on your assessment notice.
- Collect Recent Market Data: Gather 3–5 comparable home sales in your immediate neighborhood that sold for less than your assessed value.
- Submit Online or by Mail: File online via your county’s tax assessor portal (e.g., Fulton Assessor, Cobb Tax Assessor) or send your Georgia PT-311A appeal form via certified mail postmarked before midnight on your deadline date.
