How to Appeal Property Taxes in Georgia: County-by-County Guide

Georgia property taxes are moderate by national standards, with an average effective rate around 0.90%. But that average masks significant variation. In metro Atlanta counties like Fulton, DeKalb, and Gwinnett, values have surged in recent years, pushing tax bills well above what many homeowners expected.

The good news is Georgia gives homeowners a clear path to challenge their assessments. The process is straightforward, doesn't cost anything to start, and can result in meaningful savings.

How Georgia Property Tax Assessments Work

Georgia assesses property at 40% of fair market value. This 40% figure is your "assessed value." Your tax bill equals the assessed value minus exemptions, multiplied by the local millage rate.

For example, a home with a fair market value of $350,000 has an assessed value of $140,000. Subtract a $2,000 homestead exemption, and you're taxed on $138,000. At a combined millage rate of 30 mills (school, county, city), that's about $4,140 per year.

County Tax Assessors determine fair market value annually. They mail assessment notices in the spring, typically between March and June depending on the county.

Key Deadlines

45 Days from Assessment Notice

You have 45 days from the date on your annual notice of assessment to file an appeal. This is the critical deadline. The date varies by county since notices go out at different times. Don't wait until the last week.

January 1, 2026

The valuation date. Your property is valued as of this date, so sales and conditions around this time are what matter for your appeal.

Step-by-Step: Appealing Property Taxes in Georgia

Step 1: Review Your Assessment Notice

When you receive your annual notice of assessment, check the fair market value against what you believe your home is actually worth. Also review the property details. Wrong square footage, extra rooms, or incorrect lot sizes are common errors that inflate values.

Step 2: File an Appeal with the Board of Tax Assessors

Submit a written appeal (called a "return" or "appeal") to your county Board of Tax Assessors within 45 days of the notice date. Most counties accept appeals:

• In writing via mail or fax
• In person at the Tax Assessor's office
• Online (some counties, including Fulton and Gwinnett)

Your appeal should state that you believe the fair market value is too high and provide a value you think is correct. You don't need to submit evidence at this stage, but having it ready speeds up the process.

Step 3: Informal Review with the Assessor

After filing, the Board of Tax Assessors reviews your appeal. They may invite you for an informal meeting. This is your chance to present comparable sales, equity data, and property condition information. Many appeals get resolved at this stage with a negotiated reduction.

Step 4: Board of Equalization Hearing

If you don't reach an agreement with the Assessor, your case goes to the county Board of Equalization (BOE). This is a panel of citizens who hear both sides and make a decision.

At the BOE hearing:

• You present your evidence first
• The Tax Assessor presents their case
• The board asks questions and deliberates
• You receive a decision, usually within a few weeks

Alternatively, you can bypass the BOE and request a hearing officer (a certified appraiser appointed by the county). Many homeowners find hearing officers more knowledgeable about property valuation.

Step 5: Superior Court or Arbitration

If the BOE or hearing officer decision isn't satisfactory, you can appeal to Superior Court within 30 days. For properties valued under $750,000 (per Georgia code), you can also opt for binding arbitration, which is faster and less expensive than court.

Building Your Evidence

Comparable Sales

The strongest evidence in any Georgia property tax appeal. Find 3-5 sales of similar properties in your area that closed for less than your assessed fair market value. The best comps are:

• Within 1 mile of your property
• Similar in size (within 15-20% of square footage)
• Similar age and construction
• Sold between July 2025 and January 2026

Assessment Equity

If similar homes in your neighborhood have lower fair market values on the tax rolls, you have a uniformity argument. Pull assessment records for comparable properties and show the disparity.

Property Issues

Foundation cracks, outdated electrical, roof damage, drainage problems, proximity to noise or commercial areas: all of these reduce value. Document with photos and repair estimates.

Major Metro Atlanta Counties

Fulton County

Fulton covers much of Atlanta and has seen some of the most aggressive assessment increases in the state. The Tax Assessor's office has been under scrutiny for large, seemingly arbitrary jumps. Check your value carefully and compare to recent sales. Fulton accepts online appeals.

DeKalb County

DeKalb has a history of assessment controversies. Values in some areas have increased dramatically while services haven't kept pace. The BOE process here handles a large volume, so expect scheduling delays.

Gwinnett County

One of the fastest-growing counties in Georgia. For detailed Gwinnett filing instructions, see our Gwinnett County property tax appeal guide. Assessment increases have been substantial in areas like Lawrenceville, Suwanee, and Duluth.

Cobb County

Cobb County (Marietta, Kennesaw, Smyrna) generally has efficient processing. Their online portal works well for filing and tracking appeals.

Cherokee County

Rapid suburban growth has driven values up. Many new homeowners are surprised by assessments that exceed their purchase price, which is actually a strong basis for appeal if the assessment is higher than what you paid.

Georgia Homestead Exemptions

Before appealing, make sure all applicable exemptions are in place. Georgia offers several at the state and county level:

• Standard Homestead Exemption: Varies by county, typically $2,000-$10,000 off assessed value for school taxes
• Senior Exemptions: Additional reductions for homeowners 62+ or 65+, varying by county
• Disabled Veteran Exemption: Up to $101,754 off assessed value for 100% disabled veterans (adjusted annually)
• Floating Homestead: Some counties freeze the assessment at the base year value

Tips for a Successful Georgia Appeal

• File early. Don't wait until day 44. Filing early gives the Assessor more time for informal resolution.
• Get your property card. Request your property record card from the Assessor's office. Check every detail: square footage, year built, number of rooms, condition rating.
• Use the hearing officer option. In many counties, a hearing officer (licensed appraiser) produces better outcomes than the citizen BOE panel.
• Be specific. Don't just say "my value is too high." State a specific value you believe is correct and back it up with data.
• Stay calm and professional. The BOE members are volunteers. Presenting your case clearly and politely goes a long way.

Frequently Asked Questions

What is the deadline to appeal property taxes in Georgia?

You have 45 days from the date on your annual notice of assessment. Since counties mail notices at different times (typically March through June), your deadline depends on your county. Check the date printed on your notice.

How much does it cost to file a property tax appeal in Georgia?

Filing with the Board of Tax Assessors and going through the Board of Equalization is free. If you opt for a hearing officer, the county covers the cost. Superior Court filing fees apply if you appeal that far, and you'd likely want legal representation at that point.

What is the 40% assessment ratio in Georgia?

Georgia law requires property to be assessed at 40% of fair market value for tax purposes. If the assessor says your home is worth $300,000, the assessed value on your tax bill will be $120,000. Your taxes are calculated on that $120,000 figure, minus exemptions.

Can my assessment go up after an appeal?

At the Board of Equalization, the board can increase, decrease, or maintain the value. However, this is rare. In practice, the BOE almost always either reduces the value or leaves it unchanged. The risk of an increase exists but is minimal.

Should I appeal every year?

It depends. If your assessment increased significantly and you have evidence it's above market value, absolutely. If your value held steady or the market in your area supports the number, an appeal without evidence is unlikely to help. Review each year's notice on its merits.

What's the difference between the Board of Equalization and a hearing officer?

The Board of Equalization is a panel of citizens from your county. A hearing officer is a state-certified appraiser assigned to hear cases. Many homeowners prefer hearing officers because they have professional appraisal knowledge and may better understand valuation arguments. You choose one or the other when your appeal moves past the Assessor.

Can I appeal if I just purchased my home?

Yes. If the county's assessed fair market value is higher than what you paid in an arm's-length transaction, your purchase price is excellent evidence. Even if the assessment matches your purchase price, you can still appeal on equity grounds if similar homes are assessed lower.

How do I find comparable sales for my Georgia appeal?

County tax records (available on most county assessor websites), real estate listing sites, and your local MLS are all sources. Look for sales within 1 mile, similar size and age, and within the last 12-18 months. PropertyTaxFight can also help you identify the strongest comparables.

What if I missed the 45-day deadline?

Unfortunately, missing the deadline means you generally can't appeal for that tax year. Mark your calendar for next year's notice. In some rare cases, errors on the property record (wrong square footage, for example) may be correctable outside the appeal window through a request to the Assessor.

Do I have to pay my taxes while the appeal is pending?

Yes. Georgia requires you to pay the undisputed portion of your tax bill while the appeal is pending. If you're appealing a value of $300,000 and you think it should be $250,000, you'd pay taxes based on $250,000 and the remainder would be settled after the appeal.
