An assessment in Chatham County, Georgia, may not tell the whole story about your property. Its condition, location, and comparable sales can all affect the case for a different value. Reviewing your assessment is a useful first step when the number does not seem to fit your home.
A Chatham County property tax appeal is a formal challenge to an assessment, with filing rules and evidence requirements specific to Georgia. Review your notice, confirm the applicable valuation date, and check the official local instructions before filing. The guide below brings together the countyβs filing details, process, and resources so you can understand what preparation is involved.

Step 1: Read the notice date.
Your Notice of Assessment arrives from the Chatham County Board of Assessors, typically in June. The 45 days run from the date on it.
Step 2: Check the fair market value.
The notice shows a fair market value and the 40% assessed value derived from it. Your appeal targets the fair market value.
Step 3: Document the coastal facts.
Flood zone, elevation, unrepaired storm or wind damage, historic-district restrictions. In Chatham this is often the difference between a denial and a reduction.
Step 5: File Form PT-311A in writing
with the Board of Assessors before the 45 days run out.
Step 6: Settlement conference, then the board.
Georgia requires the assessors to offer a conference. If it does not resolve, the Chatham County Board of Equalization hears the case.
Step 7: The freeze.
A value reduced on appeal is generally held for the following two tax years under O.C.G.A. Β§ 48-5-299(c).

In the meantime, here's general information about how a property tax appeal works in Chatham County. Check the county's official site for current deadlines and fees.
The Chatham County Board of Assessors values everything from Victorian District row houses to Pooler new builds to Tybee Island cottages, and it does it with mass appraisal models. Those models handle square footage and build year well. They handle a coastal market badly.
Georgia assesses at 40% of fair market value (O.C.G.A. Β§ 48-5-7). The ratio is fixed statewide, so a Chatham County appeal is an argument about the fair market value the county assigned.
You have 45 days from the date on your Notice of Assessment to appeal in writing (O.C.G.A. Β§ 48-5-311). Chatham mails in June β in the 2026 cycle notices went out June 16 and the county set the appeal and exemption deadline at July 31, 2026. Read your own notice for the operative date.
Coastal value is not a smooth surface. Two houses a block apart can sit in different flood zones, and the one with the worse zone carries higher insurance, a smaller buyer pool and a lower sale price β none of which an automated model necessarily sees. Storm and wind damage that has not been repaired rarely makes it into county records. Elevation, drainage and proximity to the marsh all move price in ways square footage does not capture.
Savannah's historic districts add another layer. A landmark-district property carries renovation restrictions that constrain what a buyer can do with it, and a model comparing it to an unrestricted house of the same size is comparing two different products.
Roughly 30% to 60% of properties nationally are over-assessed. About 5% of owners appeal.
Under O.C.G.A. Β§ 48-5-299(c), a value changed through appeal is generally frozen for the following two tax years β worth watching in a market where coastal values have moved hard in short stretches.

It affects your property's fair market value, which is what the assessment is supposed to reflect. A worse flood zone means higher insurance and a smaller buyer pool, and both show up in sale prices. Chatham's mass appraisal models do not always capture it, which is exactly the kind of gap an appeal is for.
Unrepaired damage lowers market value and frequently is not reflected in county records. Photograph it, get repair estimates, and put both in the appeal.
Georgia's statewide assessment ratio (O.C.G.A. Β§ 48-5-7). Property is assessed at 40% of fair market value and taxed at the local millage rate. An appeal challenges the fair market value, not the 40%.
Usually market value. Both grounds exist in Georgia, but recent comparable sales are what a Board of Equalization weighs most heavily.
Generally yes. O.C.G.A. Β§ 48-5-299(c) freezes a value set through appeal for the following two tax years, with limited exceptions such as substantial improvements to the property.
