How Property Taxes Are Calculated in Liberty County
Liberty County uses the same statewide formula as the rest of Georgia:
- Fair Market Value (FMV): Set by the Liberty County Board of Tax Assessors, generally based on recent comparable sales.
- Assessed Value: 40% of fair market value statewide, including in Liberty County.
- Millage Rate: Set annually by the county, the Liberty County School System, the Hospital Authority, the Development Authority, and (if you live in an incorporated city that levies its own tax) your city government.
- Tax Bill: Assessed Value ÷ 1,000 × Total Millage Rate = Tax Owed, before exemptions.
Liberty County’s overall millage rates run higher than most of its neighbors. County finance officials point to Fort Stewart, which occupies 31% of the county’s land and cannot be taxed, plus large areas of marshland, as key reasons the taxable land base is smaller relative to the county’s service costs than in surrounding counties.
Worked Example: $275,000 Home in Hinesville
| Fair Market Value | $275,000 |
| Assessed Value (40%) | $110,000 |
| County millage (Hinesville rate) | 18.314 |
| School millage | 14.114 |
| Hospital Authority millage | 3.789 |
| Development Authority millage | 2.000 |
| City of Hinesville millage | 9.980 |
| Total millage | 48.197 |
| Estimated tax (pre-exemption) | $5,301.67 |
That’s $110,000 ÷ 1,000 × 48.197 = $5,301.67 per year before any homestead exemptions are applied. Hinesville’s county-portion millage (18.314) is lower than the rest of the county (20.3–20.9) because city residents aren’t charged twice for services like fire protection that the city itself provides.
2025 Millage Rates by Jurisdiction
Every Liberty County property pays the same base of School (14.114), Hospital Authority (3.789), and Development Authority (2.000) millage. On top of that, the county levies a different rate depending on whether you live in Hinesville, in Walthourville or Flemington (which began levying their own city millage for the first time in 2025), or elsewhere.
| Jurisdiction | Total Millage | Est. Effective Rate |
|---|---|---|
| City of Walthourville | 52.256 | 2.09% |
| City of Hinesville | 48.197 | 1.93% |
| City of Flemington | 43.085 | 1.72% |
| Midway, Riceboro, Gum Branch & Allenhurst | 40.803 | 1.63% |
| Unincorporated Liberty County | 40.256 | 1.61% |
Walthourville passed its first-ever city property tax in November 2025 (12 mills), and Flemington adopted its first city millage (2.829 mills) in mid-2025 — both cities previously had no municipal property tax at all. Midway, Riceboro, Gum Branch, and Allenhurst do not currently levy their own separate city millage and are billed under the county’s general “other incorporated” rate. Liberty County’s overall rates are meaningfully higher than nearby Bryan, Chatham, and Effingham counties; local officials attribute this in part to Fort Stewart’s tax-exempt land and extensive marshland limiting the county’s taxable base. Rates shown are estimates based on officially reported 2025 millage rates and are not a substitute for your actual tax bill.
Exemptions in Liberty County
Liberty County offers several local exemptions on top of the state baseline. Local exemption amounts supersede the state amount whenever they’re more generous. Every homeowner should start with the standard homestead exemption; several others may apply depending on your age, income, or veteran status.
Standard Homestead Exemption
Available to all homeowners who own and occupy their home as their legal residence. A $2,000 exemption is deducted from the 40% assessed value, applying to county M&O, county school M&O, and the state mill rate (not bonded indebtedness).
Standard Elderly School Tax Exemption
Homeowners 62 or older whose net income doesn’t exceed $10,000 for the prior year qualify for up to $10,000 off the assessed value, applied to school tax only (including school bond debt).
Standard Elderly General Homestead Exemption
Homeowners 65 or older whose net income (and spouse’s) doesn’t exceed $10,000 for the prior year (Social Security and certain retirement income excluded) qualify for $4,000 off the assessed value, applied to county, school, and state tax, including bonded debt.
Age 65+ Exemption from State Ad Valorem Taxes
Homeowners 65 or older who already qualify for another homestead exemption also receive a 100% exemption from the state portion of ad valorem tax on their home and up to 10 acres of land.
Disabled Veterans Exemption
Qualifying disabled veterans (with VA or physician documentation of a serious service-connected disability) receive up to $50,000 off the assessed value, applied to all ad valorem levies. The unremarried surviving spouse of a U.S. service member killed in any war or armed conflict qualifies for the same $50,000 exemption.
Floating (Varying) Homestead Exemption
Homeowners 62 or older with gross household income of $30,000 or less can elect this exemption, which grows as the home’s value rises. It applies only to state and county tax (not school) and replaces any other state/county exemption already in place — the county cautions that in some cases this can initially increase total taxes, so ask the Tax Assessor’s office before switching.
Surviving Spouse of a Firefighter or Peace Officer Killed in the Line of Duty
The unremarried surviving spouse of a firefighter or peace officer killed or fatally injured in the line of duty receives a full exemption from all ad valorem taxes on the home.
How and When to Apply
Homestead applications are filed with the Liberty County Tax Assessor’s Office (first-time applicants should bring a copy of their warranty deed):
Main Office: 112 N. Main St., Room 106, Hinesville, GA 31313 — (912) 876-3389
Midway Office: 9397 E. Oglethorpe Hwy, Midway, GA 31320 — (912) 884-3500
Applications are accepted year-round but must be received by April 1 to apply to that tax year. Once granted, exemptions renew automatically unless you change residence, ownership, or want to switch to a different exemption type.
