Georgia property tax appeal deadline is 45 days from your Notice of Assessment. Complete county-by-county timeline, how to calculate your deadline, and what happens if you miss it.
Under O.C.G.A. § 48-5-311, Georgia property owners have exactly 45 days from the date on their Notice of Assessment to file an appeal with their county Board of Tax Assessors. Unlike Texas — where the deadline is triggered by the mailing date — Georgia's deadline is typically calculated from the date printed on the notice itself. The 45-day clock starts on the date of the notice, not the date you received it. If your notice is dated May 1, 2026, your appeal deadline is June 15, 2026. Filing one day late means your appeal is rejected.
Georgia's 159 counties each operate their own tax assessor's office, and notice mailing timelines vary by county. Most Georgia counties mail notices between April and June, with the largest counties (Fulton, Gwinnett, Cobb, DeKalb) typically mailing between April and May.
The calculation is straightforward: find the date printed on your Notice of Assessment and add 45 days. That is your deadline. Georgia does not have a statewide uniform deadline like Texas's May 15 — your deadline is specific to your county and your notice date.
To validly appeal your Georgia property tax assessment, you must file a written notice of appeal with your county Board of Tax Assessors by the 45-day deadline. The appeal must identify your property and state that you are appealing — basic language is sufficient. Georgia allows you to appeal for three reasons: you disagree with the fair market value, you believe the assessment ratio is incorrect (should be 40% of fair market value), or an exemption was improperly denied. TaxAppeal files your appeal via USPS certified mail with return receipt — creating a legally documented record that your appeal was mailed before the deadline. Georgia, unlike Florida, requires postmark by the deadline — not receipt.
If you miss the 45-day window, the county's assessment becomes final and you cannot appeal until the following year. There are no extensions and no second chances. You will pay taxes on the inflated value for the entire year. This is why acting quickly after receiving your notice is essential. Don't set it on a pile of mail — the 45-day window closes faster than most homeowners expect.

TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
