Over-Assessment Oversight: Appealing Property Taxes in Georgia Due to Valuation Discrepancies

Posted by Daniel Jones on Feb 9, 2026 2:45:00 PM

In Georgia, property taxes are based on the assessed value of your home—typically calculated as 40% of its fair market value (O.C.G.A. § 48-5-7). If your property appears to be valued too high compared to similar homes in your area, you may be the victim of an over-assessment—and you have the legal right to appeal.

🧾 Understanding Over-Assessment

Over-assessment occurs when the county’s Board of Tax Assessors places a higher value on your property than what it could reasonably sell for on the open market. This can happen due to:

  • 📉 Market Fluctuations: Assessed values may lag behind changes in your local real estate market.

  • 🏚️ Inaccurate Property Details: Errors in square footage, number of rooms, or condition can inflate your value.

  • 📊 Mass Appraisal Methods: Georgia counties often use mass appraisal techniques, which may not capture the specifics of your property.


💸 The Cost of Over-Assessment

An overvalued home results in higher property taxes than necessary. This can lead to financial strain and unfair taxation—especially if neighboring, similar homes are taxed less.


✅ Steps to Appeal Your Property Tax in Georgia

 

1. 📚 Gather Comparable Sales ("Comps")

  • Use recent sales (within the last 12 months) of homes similar to yours in size, condition, age, and location.

  • Look for comps that sold for less than your assessed value.

  • Use sites like Zillow, Realtor.com, or county tax assessor websites.

 

2. 🏡 Document Property Characteristics

  • Highlight any issues that lower value (e.g., old roof, outdated kitchen, foundation cracks).

  • Provide proof of needed repairs, neighborhood nuisances, or unusual lot characteristics.

 

3. 🔎 Review County Assessment Records

  • Visit your county’s Board of Assessors website to verify that your property’s details are correct.

  • Errors in square footage or features can be used to justify a reduced value.

 

4. 📝 File Your Appeal

  • You have 45 days from the date on your Annual Notice of Assessment to file.

  • You can appeal online, by mail, or in person, depending on the county.

  • Clearly state your opinion of value and include all supporting documentation.

 

5. 👩‍⚖️ Present Your Case

  • If the Board of Assessors does not agree with your proposed value, your appeal may go to the Board of Equalization (BOE).

  • You can also select other resolution options like Hearing Officer (for non-homestead property over $500,000) or Non-Binding Arbitration.


 

📌 Important Georgia Notes

  • In Georgia, assessed value = 40% of fair market value.

  • Homestead exemptions and other property tax relief measures apply after the assessed value is determined.

  • The tax bill may be based on the higher assessed value while your appeal is pending. If successful, adjustments (and refunds, if applicable) will follow.


 

🛠️ Final Tip

If you're unsure how to proceed or if your case is complex, consider consulting a property tax consultant or a real estate appraiser. They can help build a stronger case and represent you during the appeal process.

By taking the time to appeal an over-assessment, you’re not only advocating for a fairer tax bill—you’re helping ensure equity across your entire tax district.
