Property Taxes in Georgia: Rates, Exemptions, and Appeals

Property taxes in Georgia are calculated by taking 40% of your property’s fair market value, subtracting any exemptions you qualify for, and multiplying what’s left by the combined millage rate set by your county, school district, and city. The county Board of Tax Assessors fixes that fair market value as of January 1 each year, and the bill usually arrives in the fall with a December 20 due date. Two homes with the same market value can produce very different bills depending on the county, the exemptions claimed, and the local budgets for schools, roads, and public safety.

How Your Tax Bill Is Calculated

Georgia uses a uniform assessment ratio. Whatever the assessor concludes your property is worth on the open market, the taxable “assessed value” is exactly 40% of that figure.¹ A home appraised at $350,000 carries an assessed value of $140,000. Every exemption and millage calculation starts from that 40% number, not the full market value.

Fair market value itself is defined by statute as the price a knowledgeable buyer would pay and a willing seller would accept in a genuine arm’s-length transaction. Recent buyers have a built-in protection: the sale price of your most recent arm’s-length purchase is the ceiling the assessor can use for the following tax year. If you paid $300,000 and nearby homes have since risen to $330,000, your assessment can’t exceed $300,000 that next year.²

The millage rate is where location drives the result. A mill equals one dollar of tax for every $1,000 of assessed value.³ Your total rate stacks several rates together: the county’s general rate, the school district rate, and often a municipal rate or special district levy. Each entity sets its own figure annually.

Here’s the math in practice. Take that $350,000 home with a $2,000 homestead exemption and a combined rate of 30 mills. Assessed value is $140,000. Subtract the $2,000 exemption and you have $138,000 in taxable value. Multiply by 0.030 and the annual bill is $4,140. The same home in a county levying 25 mills would owe $3,450.

Agricultural and Conservation Land

If your land is in bona fide agricultural use, it’s assessed at 75% of what regular property would be—30% of fair market value rather than 40%.¹ Conservation use property is assessed at 40% of current use value instead of fair market value, which can be substantially lower for undeveloped land.⁴ Both require the land to actually be in that use, and breaking the covenant brings penalties.

Exemptions That Lower the Bill

To claim any homestead exemption you must own and occupy the property as your primary residence on January 1 of the tax year.⁵ Applications are due by April 1, though Georgia now lets you apply as late as the end of the 45-day assessment appeal window.⁶

Standard Homestead Exemption

The basic state exemption reduces your assessed value by $2,000 for county and school taxes, excluding taxes levied to retire bonded debt.⁶ The dollar savings alone are modest, but filing the standard exemption also opens the door to the more valuable local and age-based exemptions. Many counties have passed their own legislation offering higher amounts that stack on top of the state baseline.

Senior and Age-Based Exemptions

Georgia residents 62 and older with combined household income at or below $10,000 (excluding certain retirement and Social Security income) can claim an additional exemption of up to $10,000 off the homestead’s assessed value for school taxes.⁶ A separate floating inflation-proof exemption is available for homeowners 62 and older whose household income does not exceed $30,000. That one shields you from county tax increases caused by natural appreciation in your home’s value, effectively freezing your county tax liability. It does not apply to school or municipal taxes.

Some counties go further, freezing the assessed value at a base-year level for as long as a qualifying senior occupies the home. The specifics vary, so a call to your local tax commissioner’s office is worth the time.

Disabled Veterans

Qualifying disabled veterans receive an exemption indexed annually by the U.S. Secretary of Veterans Affairs. For 2025, the amount was $121,812, applied against state, county, municipal, and school taxes on the veteran’s homestead.⁷ Any value above the exemption remains taxable, and because the figure changes each year, veterans should confirm the current number with the county tax commissioner or the Georgia Department of Veterans Service.

Surviving Spouses of Peace Officers and Firefighters

The unremarried surviving spouse of a peace officer or firefighter killed in the line of duty qualifies for a full homestead exemption, eliminating all property taxes on the home for as long as the spouse continues to occupy it.⁶

Business Inventory (Freeport)

Businesses holding inventory in Georgia should check whether their county and city have adopted the freeport exemption. Participation is a local choice, and the exempt percentage can be set at 20%, 40%, 60%, 80%, or 100% of inventory value.⁸ Level 1 covers goods being manufactured, finished goods held by the producer for up to 12 months, warehouse inventory destined for out-of-state shipment within 12 months, and fulfillment center stock. Level 2 covers general business inventory outside those categories. Applications go to the Board of Tax Assessors during the same window as property tax returns, with partial relief possible for applications filed by June 1.

When Taxes Are Due and What Late Costs

Property taxes in Georgia are due by December 20 unless your county has adopted an earlier deadline, and some counties split the bill into two installments with separate due dates.⁹ Bills typically arrive in early fall. You can pay the county tax commissioner online, by mail, or in person. Many homeowners pay through a mortgage escrow account that bundles the tax into the monthly house payment.

Missing the deadline gets expensive quickly. A 5% penalty hits any unpaid tax 120 days after the due date, and another 5% is added every 120 days after that, up to 20% of the original amount owed.¹⁰ Interest accrues on top of the penalties at the prime banking rate plus 3%, compounding until paid. One county’s reported 2026 monthly rate is 0.8125%, roughly 9.75% annualized. Within a couple of years, penalties and interest can add 30% or more to the original bill.

If the balance stays outstanding, the county can issue a fi. fa. (fieri facias), a tax lien recorded against both the property and the owner of record as of January 1. The property then becomes eligible for levy and sale at public auction, held on the first Tuesday of the month in counties with sales scheduled. The former owner (or anyone with a legal interest in the property) has 12 months from the sale to redeem by paying the bid amount, any taxes the purchaser has paid since, special assessments, and a 20% premium for the first year. After that first year, the premium rises by 10% per additional year or fraction of a year.¹¹ Losing a home to a tax sale over a few thousand dollars in unpaid taxes happens, and even redemption is costly.

How to Appeal Your Assessment

Each year the Board of Tax Assessors mails an Annual Notice of Assessment showing the current fair market value and assessed value. If the number looks wrong, you have 45 days from the notice date to file a written appeal with the county board.¹² A letter stating your grounds is enough, though the Department of Revenue also provides a standard form (PT-311). You can challenge the value itself, argue the assessment is uneven compared to similar properties, or contest an exemption denial.

Choosing Your Appeal Path

When you file, you pick one of three options:

Board of Equalization. The default for most homeowners. Three members appointed from the county, each required to own real property locally and complete 40 hours of appraisal training in their first year. The board holds a hearing within 30 days of notifying both sides and announces its decision at the end of the hearing.¹³
Hearing Officer. Available only for non-homestead real property or wireless telecom personal property with an aggregate fair market value over $500,000. This path is built for commercial and higher-value disputes.¹²
Nonbinding Arbitration. Covers value disputes for real or personal property, and as the name says, neither side is bound by the result.

Building Your Case

The strongest appeals tie concrete evidence to the January 1 valuation date. Recent comparable sales within roughly a half-mile of your property carry the most weight. A private appraisal from a state-credentialed appraiser helps too, provided it reflects the property’s condition as of January 1 of the tax year under appeal. These appraisals typically run $300 to $600 for a single-family home, so they pay off when the potential tax savings over several years justify the cost. Photographs documenting deferred maintenance or outdated finishes that cut value compared with the comparables can support the argument.

If the Board of Equalization rules against you, you can appeal to Superior Court within 30 days of the written decision.¹³ That stage involves more formal procedure and usually an attorney, so most homeowners work to resolve things at the Board of Equalization first.

A Few Boundaries Worth Knowing

Vehicles are not part of your real property tax bill. Most vehicles purchased on or after March 1, 2013 are subject to the Title Ad Valorem Tax, a one-time 7% of fair market value paid when the title transfers, which replaced the old annual vehicle property tax.¹⁴ New residents registering an out-of-state vehicle pay 3%, and immediate-family transfers or inheritances pay 0.5%. Older vehicles and non-titled vehicles like trailers still use the annual ad valorem system, due by the last day of your birthday-based registration period, with a 10% penalty for missing it.

You generally don’t need to file a property tax return. Georgia law sets a January 1 to April 1 filing window with the county tax receiver or commissioner, but if you filed or paid the previous year and nothing has changed, you’re treated as having filed again at the same value and exemptions.⁹ The same applies if a real estate transfer tax form was filed when you bought the home. You do need to file when you’ve made improvements to a property acquired the prior year, or when you’re applying for a homestead or personal property exemption for the first time.
