Georgia property tax: the complete homeowner's guide

The big picture

Georgia's effective property tax rate sits around 0.77% of market value — below the national average. Two structural features explain why. First, Georgia has no statewide property tax for general operations: the state ad valorem levy was phased out and has been zero since January 1, 2016, so property tax is purely a local affair levied by counties, cities, and school districts. Second, property is not taxed on its full value — it is assessed at 40% of fair market value. That 40% ratio, applied to a market that is moderate by national standards, is the single biggest reason Georgia's effective rate stays low.

Because the tax is entirely local, there is no one Georgia rate. Each county, city, and school district sets its own millage, and the combined millage is what turns your assessed value into a bill. Two homes with the same market value — one in metro Atlanta, one in a rural county — can carry very different bills depending on where the millage lands.

How a Georgia tax bill is built

The bill is assembled in a few clear steps:

1. The county Board of Tax Assessors determines your home's fair market value. Georgia requires annual valuation — all property is to be returned and assessed at fair market value every year, and counties compare digest values against recent sales.
2. The assessor applies the 40% assessment ratio: assessed value equals 40% of fair market value, unless a different ratio is specified by law. A $300,000 home, for example, carries a $120,000 assessed value before any exemptions.
3. Exemptions are subtracted from the assessed value — starting with the $2,000 standard homestead exemption for an owner-occupied primary residence, plus any age or veteran exemptions you qualify for.
4. The combined millage of your county, city, and school district is applied to the net assessed value. A mill is one dollar of tax per $1,000 of assessed value, and the millage that funds schools is typically the largest single component.

Bills are issued and collected by your county Tax Commissioner, not the state. The Georgia Department of Revenue's pay-property-tax-online page routes you to the right county portal to look up and pay what you owe.

Exemptions: where the savings live

Georgia's exemptions reduce the assessed value your millage is applied to. The homestead exemptions worth knowing:

• $2,000 standard homestead exemption. The statewide base exemption, applied to county and school taxes for an owner-occupied primary residence. You must own and occupy the home as your legal residence to qualify, and you apply once with your county.
• Age 65+ exemption. An additional $4,000 off assessed value for qualifying owners 65 and older, subject to an income limit.
• Age 62+ education exemption. Owners 62 and older may qualify for an exemption of up to $10,000 of assessed value against school (education) taxes — meaningful because school millage is usually the largest part of the bill.
• Disabled veteran exemption. A substantial exemption for qualifying disabled veterans — $121,812 of assessed value for 2025, a figure that is adjusted over time.

On top of these flat exemptions, Georgia enacted a statewide floating homestead exemption under HB 581. Rather than a fixed dollar amount, it exempts the amount by which your homestead's current-year assessed value exceeds an adjusted base-year value — effectively capping the taxable growth of your assessment to the consumer price index. The base year is the 2024 digest, and the first inflation index applies to the 2026 digest (there is no index for 2025). The exemption is statewide, but any county, city, consolidated government, or school district is allowed to opt out, so whether it applies to your bill depends on your local jurisdictions' decisions.

A 2025 follow-on law, HB 92, narrowed the floating exemption: it limits the benefit to a primary residence plus up to 5 contiguous acres, and it requires jurisdictions that opted out to print an opt-out notice and phone number on tax bills.

Appealing your assessment

Because the bill flows from the county's fair-market-value estimate, the value is where most homeowners have leverage. If you believe your assessment overstates what your home would actually sell for, Georgia's process generally runs through the county Board of Tax Assessors and, if unresolved, the county Board of Equalization. The broad shape of an appeal:

• Start with the assessment notice. When the county mails your annual notice of assessed value, review the fair market value it assigns — that number, times 40%, drives your assessed value.
• File an appeal with the county. Georgia provides a formal appeal path through the Board of Tax Assessors; an unresolved appeal can escalate to the county Board of Equalization (or other options the county offers).
• Bring evidence of market value. Recent comparable sales, a private appraisal, or documented condition issues are the kinds of evidence that support a lower fair market value — and a lower assessed value follows automatically from the 40% ratio.

Because appeal deadlines and procedural details are set at the county level, check your specific county's notice and Tax Commissioner or assessor page for the exact dates and forms. Run our assessment appeal savings calculator to see what even a modest reduction in your fair market value would do to your bill.

County-by-county variation

The 40% assessment ratio is uniform statewide, but everything downstream of it is local. Your combined millage is the sum of the rates your county, city, and school district each adopt, and those rates differ widely across Georgia. Metro-Atlanta counties and municipalities with large school budgets tend toward higher combined millage; rural counties often sit lower. The Georgia DOR publishes millage rate information at the local-government level.

This is why a single statewide "Georgia property tax rate" is misleading. To see how a specific area compares, our Georgia property tax by ZIP code lookup shows the median tax, median home value, and effective rate for each ZIP from the Census American Community Survey, alongside the state and national medians.

Common Georgia mistakes

• Not filing the homestead exemption. The $2,000 standard homestead is not automatic for a new owner-occupant — you have to apply with your county. Skipping it leaves money on the table every year.
• Missing the age-based exemptions. The age-65 and age-62 education exemptions stack on top of the standard homestead, and the education exemption hits the largest part of the bill. Owners often don't realize they qualify the year they become eligible.
• Assuming HB 581 applies to you. The floating exemption is statewide, but your county, city, or school district may have opted out — and HB 92 limits it to a primary residence plus 5 contiguous acres. Check whether your jurisdictions opted out before counting on the cap.
• Treating the assessed value as the market value. Your assessed value is only 40% of fair market value. A homeowner who reads the assessed value as a market estimate can badly misjudge both their home's worth and whether an appeal is worth filing.

Putting it together

Georgia's low effective rate is not an accident — it comes from the 40% assessment ratio and the absence of a statewide operating levy, layered with a $2,000 homestead exemption, stacking age and veteran exemptions, and now HB 581's inflation cap on taxable growth. The bill itself is purely local: the county assesses at 40% of fair market value every year, and county, city, and school millage turns that into what you owe.

The mistakes that cost the most are passive — not filing the homestead, missing an age exemption, or never questioning an inflated valuation.
