Let’s be real: property taxes in Georgia can feel like a surprise bill that shows up every year without fail. Whether you own a home in Atlanta, a rental property in Savannah, or land in rural Georgia, understanding Georgia tax valorem (also called ad valorem tax) is the difference between paying what you owe and overpaying by hundreds or thousands of dollars annually.
Georgia’s ad valorem tax system is straightforward on the surface but has enough nuances that most homeowners leave money on the table. This guide breaks down exactly how Georgia tax valorem works, who pays it, how it’s calculated, and—most importantly—how you can legally reduce your tax bill starting this year.
What Is Georgia Tax Valorem?
Georgia tax valorem is a property tax based on the assessed value of real property. The word “valorem” literally means “according to value”—so the tax you pay is directly tied to what your property is worth. Unlike income tax, which is based on what you earn, ad valorem tax is based on what you own.
Here’s the simple formula: Property Assessment Value × Tax Rate = Your Annual Tax Bill
In Georgia, every county assesses property values and sets its own millage rate (the tax rate). This means your neighbor three counties over could pay significantly different property taxes on an identical home, simply because different counties have different millage rates.
The Georgia Department of Revenue oversees the statewide assessment system, but the actual assessment and collection happen at the county level. This decentralized approach means understanding your local county assessor’s office is just as important as understanding the statewide rules.
Think of Georgia tax valorem like a subscription service for property ownership. You pay annually based on your property’s assessed value, and the bill arrives like clockwork. The difference is: you can actually negotiate your subscription price through assessment appeals.
How Is Valorem Tax Calculated in Georgia?
The calculation itself is straightforward, but the assessment process that feeds into it is where things get complicated.
Step 1: Property Assessment
Your county assessor’s office determines the fair market value of your property. In Georgia, properties are reassessed every 4 years (though some counties do more frequent assessments). The assessor uses comparable sales data, property condition, square footage, lot size, and other factors to estimate what your home would sell for on the open market.
Here’s the catch: assessors are human, and they sometimes get it wrong. A property that’s overvalued by $50,000 could cost you an extra $500–$1,000+ per year in taxes, depending on your county’s millage rate.
Step 2: Apply the Millage Rate
Once your property is assessed, the county applies its millage rate. One mill equals $1 of tax per $1,000 of assessed value. If your property is assessed at $300,000 and your county’s millage rate is 15 mills, your calculation looks like this:
$300,000 ÷ 1,000 × 15 = $4,500 annual tax bill
Different counties in Georgia have wildly different millage rates. Some counties run at 12–14 mills, while others are at 18–22 mills. This is why two identical homes in different Georgia counties can have drastically different tax bills.
Step 3: Apply Exemptions (If You Qualify)
Before you pay, Georgia allows certain exemptions that reduce your assessed value. The most common is the homestead exemption, which we’ll cover in detail next. Other exemptions exist for seniors, disabled veterans, and certain agricultural properties.
If you qualify for a $50,000 homestead exemption on that $300,000 home, your taxable value drops to $250,000, and your bill becomes:
$250,000 ÷ 1,000 × 15 = $3,750
That’s a $750 annual savings just from claiming an exemption you probably already qualify for.
The Homestead Exemption: Your First Major Savings
Georgia’s homestead exemption is the single biggest way most homeowners reduce their Georgia tax valorem bill. Yet thousands of Georgia homeowners don’t claim it, leaving free money on the table.
Here’s what you need to know:
- Basic homestead exemption: Reduces your assessed value by $50,000 (for school taxes) and $50,000 (for county/city taxes). That’s $100,000 total in exemptions if you own a primary residence.
- Age 65+ exemption: If you’re 65 or older, you get an additional exemption that can freeze your property tax at the level it was when you turned 65.
- Disabled veteran exemption: Veterans with service-connected disabilities can get exemptions ranging from $20,000 to $100,000 depending on disability rating.
- Eligibility: You must own the property as your primary residence on January 1 of the tax year. Rental properties and investment properties don’t qualify.
To claim the homestead exemption in Georgia, you file an application with your county tax assessor’s office. Most counties allow online filing, but some still require paper forms. Once approved, the exemption typically applies automatically in future years unless you move or sell.
The application is free and usually takes 15–30 minutes. Yet the average homeowner saves $750–$1,500 annually. That’s a 100% return on your time investment.
Pro Tip: If you just bought a home in Georgia, apply for the homestead exemption immediately. Some counties allow retroactive applications if you missed the initial deadline, but don’t count on it. File early, file now.
Property Assessment Appeals: Challenging Overvaluation
Here’s where most homeowners miss out on serious savings: they accept their property assessment without question.
If you believe your property is overvalued, you have the right to appeal. Georgia law requires counties to give you a formal process to challenge the assessment, and many homeowners who appeal actually win.
How Assessment Appeals Work
The process varies slightly by county, but the general steps are:
- Request your assessment: Contact your county tax assessor and get a copy of your property’s assessed value and the assessment details.
- Gather comparable sales: Research similar properties in your area that recently sold. If comparable homes sold for less than your assessment, you have grounds for an appeal. Sites like Zillow and Redfin have sales data, though professional appraisals are stronger evidence.
- File your appeal: Most Georgia counties have a deadline (usually 45 days after you receive your assessment notice). File your appeal with your county assessor or board of equalization.
- Present your case: You’ll get a hearing where you can present your comparable sales data. Many counties allow informal presentations—you don’t need a lawyer.
- Decision: The board reviews your evidence and decides whether to uphold or reduce the assessment. If you disagree with the decision, you can appeal further to Georgia’s Department of Revenue.
The appeal process is free, and if you win even a modest reduction—say $30,000–$50,000 off your assessment—you’ll save $300–$750+ per year in taxes. That’s money in your pocket for a few hours of work.
For example, if your home was assessed at $350,000 but comparable homes in your neighborhood sold for $310,000–$320,000, you have a strong case for a $30,000–$40,000 reduction. At a 15-mill rate, that’s $450–$600 in annual savings.
Warning: Don’t appeal frivolously. If you appeal and lose, you might face a higher assessment in future years as the assessor takes a closer look. Only appeal if you have solid comparable sales data showing your assessment is genuinely out of line.
County-by-County Variations Matter
Georgia has 159 counties, and each one runs its own assessment and tax system. This means your Georgia tax valorem bill depends heavily on where you own property.
For example, consider two identical $400,000 homes:
- County A (12-mill rate): $400,000 × 0.012 = $4,800/year
- County B (18-mill rate): $400,000 × 0.018 = $7,200/year
That’s a $2,400 annual difference just from location. Over 10 years, that’s $24,000.
Some specific counties to watch:
- Spalding County: Known for thorough assessments and fair processes. If you own property here, check out Spalding County Tax Assessor for county-specific guidance.
- Fulton County (Atlanta): High property values and millage rates. Appeals are common and often successful if you have good data.
- DeKalb County: Similar to Fulton. Property values are high, and many homeowners successfully appeal overvaluations.
- Gwinnett County: Rapidly appreciating area. Assessments may lag behind market reality, meaning you could be underassessed (good for you) or overassessed (depends on recent sales).
If you’re considering buying property in Georgia or already own multiple properties, understanding your specific county’s assessment practices is essential. Some counties are more aggressive with assessments, while others are more conservative. Your county assessor’s office can explain their process and show you recent assessment data.
Other Exemptions and Deductions You Might Qualify For
Beyond the homestead exemption, Georgia offers several other ways to reduce your Georgia tax valorem bill:
Agricultural Exemptions
If you own land used for bona fide agricultural purposes, you may qualify for an agricultural exemption that significantly reduces your assessed value. This applies to farms, orchards, timber land, and similar properties. The catch: you must actively farm or manage the land, not just own it.
Disabled Veteran Exemptions
Veterans with service-connected disabilities ranging from 10% to 100% can get exemptions:
- 10–30% disability: $20,000 exemption
- 40–60% disability: $40,000 exemption
- 70–99% disability: $80,000 exemption
- 100% disability: $100,000 exemption
You’ll need your VA disability rating letter to apply. Contact your county assessor for the application process.
Age 65+ Exemptions
Georgia’s “Frozen Assessment” program allows homeowners age 65 and older to freeze their property assessment at the level it was when they turned 65. If your home has appreciated significantly, this can save you thousands. However, you must apply before age 67 to qualify.
Charitable Organization Exemptions
Properties owned by qualified charitable, religious, or educational organizations may be exempt from ad valorem tax entirely. This is rarely relevant for individual homeowners, but if you own property held in trust for a nonprofit, it’s worth exploring.
Renewable Energy Exemptions
Georgia offers exemptions for solar panels and other renewable energy systems. If you’ve installed solar, you may qualify for a 10-year exemption on the added value the system brings to your home.
The key with all these exemptions: you must apply. The county won’t automatically give them to you. Contact your county assessor’s office and ask which exemptions you might qualify for.
Action Steps to Lower Your Georgia Tax Valorem Bill
Knowing about Georgia tax valorem is one thing. Actually reducing your bill is another. Here’s your action plan:
Month 1: Claim Your Homestead Exemption (If You Haven’t Already)
- Contact your county tax assessor’s office (find it by searching “[Your County] Georgia Tax Assessor”).
- Ask if you’ve already claimed the homestead exemption. If not, request an application.
- Complete the application (usually takes 15 minutes). Most counties accept online submissions.
- Submit and keep a copy for your records.
Month 2: Review Your Assessment
- Request a copy of your property’s current assessment from your county assessor.
- Write down the assessed value and millage rate.
- Calculate your annual tax bill: (Assessed Value ÷ 1,000) × Millage Rate.
- Compare this to your actual tax bill. They should match (minus any exemptions).
Month 3: Research Comparable Sales
- Use Investopedia’s guide to comparable properties to understand how to evaluate your home’s market value.
- Search your county property appraiser’s website for recent sales of similar homes.
- Look at homes with similar square footage, lot size, age, and condition that sold in the last 6–12 months.
- If the average sale price is notably lower than your assessment, you have grounds for an appeal.
Month 4: File an Appeal (If Warranted)
- Check your county’s deadline for assessment appeals (usually 45 days after the assessment notice).
- Gather your comparable sales data and any other evidence (inspection reports, photos showing needed repairs, etc.).
- Complete your county’s appeal form and submit it before the deadline.
- Prepare for your hearing by organizing your evidence clearly.
Ongoing: Check Your Bill Annually
- When you receive your annual tax bill, verify the assessed value hasn’t jumped unexpectedly.
- In Georgia, properties are reassessed every 4 years, but some counties reassess more frequently.
- If you make major home improvements, expect your assessment to increase. If you make major repairs that reduce value, you can appeal.

Frequently Asked Questions
What is the difference between assessed value and market value in Georgia tax valorem?
– Assessed value is what your county assessor determines your property is worth for tax purposes. Market value is what your home would actually sell for on the open market. In Georgia, assessed values are supposed to equal market value, but they often lag behind, especially in fast-appreciating areas. If your assessed value is significantly higher than recent comparable sales, you have grounds for an appeal.
Can I appeal my property assessment every year in Georgia?
– Yes, you can file an appeal every year if you believe your assessment is incorrect. However, most counties have a specific deadline (usually 45 days after you receive your assessment notice). If you appeal and lose, don’t appeal again the next year unless something material has changed (major damage, major improvements, or significant changes in comparable sales).
How often are properties reassessed in Georgia?
– Georgia requires reassessment every 4 years, though some counties reassess more frequently. When a reassessment happens, your assessed value may increase, decrease, or stay the same depending on market conditions and property changes. You’ll receive a notice before the new assessment takes effect, and you have the right to appeal.
What happens if I don’t pay my Georgia property taxes?
– If you don’t pay, your county will send you notices and eventually may place a tax lien on your property. If the taxes remain unpaid, the county can foreclose and sell your property at a tax sale. This is serious—don’t ignore property tax bills. If you’re having trouble paying, contact your county tax collector about payment plans or hardship options.
Do renters pay Georgia tax valorem?
– No, renters don’t directly pay property tax. The property owner (your landlord) pays it. However, property taxes are often built into rent prices, so you indirectly bear some of the cost. If you’re a renter, you don’t qualify for the homestead exemption, but you may qualify for the renter’s tax credit on your Georgia state income tax return.
Can I deduct Georgia property taxes on my federal income tax return?
– Yes, you can deduct up to $10,000 in state and local taxes (SALT) combined on your federal return if you itemize deductions. This includes property taxes, income taxes, and sales taxes combined. However, you must itemize deductions rather than taking the standard deduction for this to benefit you. For 2024, the standard deduction is $14,600 (single) or $29,200 (married), so many homeowners don’t benefit from this deduction.
What’s the millage rate for my Georgia county?
– Millage rates vary by county and can include separate rates for county government, schools, and municipalities. To find your specific millage rate, contact your county tax assessor’s office or check your county’s website. Your property tax bill should also show the millage rate used to calculate it.
If I improve my home, will my taxes go up?
– Yes, if you make significant improvements (additions, renovations, new roof, new HVAC system), your county may increase your assessed value at the next reassessment. Minor repairs and maintenance don’t trigger reassessment, but capital improvements do. If you’re planning major work, consider timing it after a reassessment cycle to delay the tax impact. This is one area where understanding your county’s reassessment schedule matters.
How do I find my county’s tax assessor’s office?
– Search “[Your County Name] Georgia Tax Assessor” online, or visit your county’s official website. Most assessor’s offices now have online portals where you can look up property values, file appeals, and sometimes even apply for exemptions. If you can’t find it online, call your county’s main government office and ask for the assessor’s contact information.
Is there a homestead exemption cap in Georgia?
– No, there’s no income limit for the homestead exemption in Georgia. Even high-income homeowners qualify, as long as the property is their primary residence. This is one of the most generous homestead exemption programs in the country.
Can I transfer my homestead exemption to a new home if I move?
– No, the homestead exemption is tied to the specific property. If you move, you’ll need to apply for the exemption on your new Georgia home. Once you move out of your old home, the exemption on that property ends. This is why it’s important to apply for the exemption on your new home as soon as you move in.
