Property Tax Appeal
Chatham County Property Tax Appeal Appraisal
Independent market evidence for Chatham County homeowners appealing their Annual Notice of Assessment — from Savannah's historic squares to the fast-growing west Chatham suburbs.
Appeal Window: Chatham County property owners generally have 45 days from the date on their Annual Notice of Assessment to file an appeal. This is based on standard Georgia procedure — always verify the exact deadline printed on your own notice and file with Chatham County Board of Assessors — boa.chathamcountyga.gov before ordering an appraisal.
The Chatham County Board of Assessors values everything from centuries-old homes near Savannah's historic squares to new-construction communities in Pooler and Garden City — genuinely different markets valued by the same countywide mass-appraisal system. When your notice doesn't reflect what your specific property would actually sell for, an independent appraisal gives you organized, defensible evidence instead of just a disagreement.
Understanding Your Notice
Understanding Your Chatham County Assessment
Who Sets Your Value
The Chatham County Board of Assessors values property and mails Annual Notices of Assessment each year; billing and collection are handled separately by the Chatham County Tax Commissioner's Office. Your notice reflects the Board of Assessors' opinion of your property's fair market value as of January 1.
Like every Georgia county, Chatham County assesses residential property at 40% of fair market value for tax purposes. An appeal challenges the county's opinion of fair market value — exactly what an independent appraisal is built to evaluate.
Your Tax Bill vs. Your Assessment
Your final tax bill layers county, school, and — inside city limits — municipal millage on top of the county's assessed value, plus any homestead exemptions you've filed. Savannah, Pooler, Garden City, Port Wentworth, and Tybee Island each set their own city millage, so identical assessed values inside and outside city limits can produce different bills. An independent appraisal speaks to fair market value — the figure actually being appealed — not the tax calculation itself.
When It May Help
Common Reasons Chatham County Assessments Get Questioned
The county's mass-appraisal model may not capture what makes your specific property in Chatham County different from its neighbors.
Recent repairs or deferred maintenance aren't reflected in the county's file on your property.
County records may list an upgrade, addition, or feature your home doesn't actually have.
Your assessment rose well beyond what comparable Chatham County sales would support this year.
Local Appeal Process
How to Appeal in Chatham County
Chatham County property owners have 45 days from the date printed on their Annual Notice of Assessment to file a written appeal using the state's PT-311A form. Appeals can be filed online, by mail to P.O. Box 9786, Savannah, GA 31412, or in person at 222 West Oglethorpe Avenue, Suite 113, inside the Pete Liakakis Government Building. Certified mail is recommended for proof of timely filing; email and fax submissions are not accepted.
You can typically file through the Chatham County Board of Assessors' online filing option (boa.chathamcountyga.gov). Georgia Valuation Source provides independent appraisal evidence for your case — we do not file appeals or provide legal representation.

Reviewed first by the Board of Assessors; if unchanged, automatically forwarded for a hearing before this citizen panel. No fee to the taxpayer.
Hearing Officer
Available for non-homestead real property or wireless property above the statutory value threshold, heard by a state-certified appraiser.
Arbitration
Requires submitting a certified appraisal with your appeal; if rejected by the Board, the case proceeds to a binding arbitration hearing.

Building Your Case
What Evidence Matters
Recent closed sales of genuinely comparable homes — similar size, age, condition, and location — with the differences between those homes and yours accounted for individually.
Photographs and a description of any condition issues, deferred maintenance, or functional problems the county's mass-appraisal model would not have observed.
Documentation of the property's physical characteristics (square footage, lot size, room count, systems age) if it differs from county records.
A clear, professionally organized opinion of value — not just a lower number, but the market evidence and reasoning behind it.

Residential Appraisal Considerations in Chatham County
Coastal and tidal influence: Marsh-front, barrier-island (Tybee Island), and other tidally-influenced properties often require specialized flood-zone and insurability analysis distinct from inland comparables.
Historic housing stock: Savannah's Historic Landmark District contains pre-1900s housing with condition and functional characteristics that generally require a different analytical approach than newer suburban construction.
New-construction growth corridor: Western Chatham (Pooler, Bloomingdale, Garden City) has seen substantial new-subdivision activity tied to port and logistics-sector growth, a distinct submarket from the historic core.

Local Market Considerations
Chatham County Market Diversity
Chatham County spans genuinely distinct markets: Savannah's historic, high-demand intown neighborhoods, established mid-county communities, and rapidly-growing new-construction suburbs in Pooler, Garden City, and Port Wentworth. A countywide mass-appraisal model calibrated to one of these submarkets can easily misstate value in another — exactly the nuance an individual appraisal is built to capture.
