A Step-by-Step Guide for Homeowners in Fulton, Cobb, DeKalb, and Surrounding Metro Counties. Feeling shocked by your new property tax bill? You’re not alone. Each year, thousands of Atlanta-area homeowners receive assessments that overstate their home’s true market value — and overpay because they didn’t realize they had options. This 2026 guide will walk you through everything you need to know to appeal your property taxes in Georgia, step-by-step, with local insight, deadlines, and evidence tips that most generic blogs miss.

Step 1: Understand the 2026 Appeal Window (It’s Short)

Every county in Georgia — including Fulton, Cobb, DeKalb, Gwinnett, and Paulding — mails out Annual Notice of Assessment letters, usually in April or May. From the date printed on that letter, you typically have 45 days to file an appeal.

Example: If your notice is dated May 1, you must file by June 15.
Miss it? You’ll have to wait until 2027 — even if the value is wrong.

Step 2: Decide If You Should Appeal

Ask yourself:

  • Does the assessed value seem higher than recent sales near you?

  • Has your home’s condition declined (repairs, age, damage)?

  • Are nearby homes assessed lower for similar features?

  • Have taxes increased substantially year over year?

If you answered yes to any of those, it may be worth appealing.

Pro Tip: Even if you bought your home recently, the county might not reflect your true purchase price.

Step 3: Gather Strong, Defensible Evidence

The success of your appeal hinges on proof — not emotion, not hope.

Best evidence includes:

Zillow “Zestimates,” tax records, or opinions without documentation hold little weight with the Board.

Step 4: File Your Appeal Online or In Person

Go to your county Board of Assessors website or office and file your appeal form. You’ll need to choose your preferred appeal path:

You’ll get a confirmation and notice of hearing in the mail.

Step 5: Prepare for Your Hearing (or Let the Appraisal Speak)

At the BOE hearing, the county will present their data and you’ll have a chance to present yours. Many homeowners choose to:

  • Attend and present their appraisal in person

  • Or, submit a written statement with documentation

A well-written, independent appraisal is often the most persuasive piece of evidence.

Should You Appeal Your Property Taxes?

If your home is genuinely over-assessed, absolutely. On average, successful appeals can reduce your taxable value by $10,000–$50,000+, which may equal hundreds or thousands in annual savings.
