How to Appeal Your Fulton County Property Tax Assessment (Step by Step)

Every summer, thousands of Fulton County homeowners open a Notice of Assessment, see a number that's gone up, and assume there's nothing they can do. There usually is. Appealing your property tax assessment is a routine, legal process in Georgia — and when the county's number is genuinely too high, an appeal can lower your bill for years, not just one.

This guide walks through the entire process the way we'd explain it to a neighbor: what the notice means, the deadline that matters most, what evidence actually wins, how to file, and what happens at a hearing. We'll also be honest about when an appeal isn't worth your time.

Step 1 — Understand your Notice of Assessment

Each year, the Fulton County Board of Assessors mails an Annual Notice of Assessment to property owners. In 2026, those notices went out around June 16; the exact date shifts a little year to year, but mid-June is the norm. This is not a bill — it's the county telling you what they think your property is worth, which is what your eventual tax bill is built on.

The number that matters is the fair market value (FMV): the county's estimate of what your home would sell for. In Georgia, your assessed value is 40% of that FMV. So a home the county values at $500,000 has an assessed value of $200,000, and your taxes are calculated against that $200,000 (after any exemptions). When you appeal, you are arguing that the FMV is too high.

Step 2 — Know your deadline: 45 days from the notice date

This is the single most important fact in the entire process. Under Georgia law, you have 45 days from the date printed on your Notice of Assessment to file an appeal. Miss it, and you generally lose the right to appeal that year's value — full stop, no matter how strong your case is.

With a mid-June notice, that window typically closes in late July. In 2026, with notices dated June 16, the deadline lands around July 31. Don't rely on a calendar rule of thumb, though — go by the actual date on your notice, because it's the only date that counts.

We treat this deadline as a hard wall, and you should too. If you're reading this in June or July, it's worth checking your assessment now rather than later. (We break the deadline down in detail in our guide to the Fulton County 45-day appeal window.)

Step 3 — Decide whether you actually have a case

Here's where we differ from most of the industry: not every assessment is worth appealing. If your FMV is in line with what comparable homes nearby are actually selling for, an appeal is unlikely to move the number — and it can cost you time for nothing.

You probably do have a case if any of these are true:

• Your FMV rose sharply this year while comparable homes near you sold for less than your new value.
• You recently bought the home for less than the county's FMV in an ordinary, arm's-length sale.
• There's an error in the property record — wrong square footage, a finished basement you don't have, a bathroom that isn't there, or condition issues the county hasn't accounted for.
• Your assessment is noticeably higher than near-identical neighbors' for no clear reason.

You probably don't have a strong case if your FMV is roughly what your home would honestly sell for today. That's not a failure — it means the county got it about right. We'd rather tell you that than file a long shot.

Step 4 — Gather evidence that wins

An appeal is only as good as its evidence. Opinions and frustration don't move a board; data does. In rough order of strength:

Recent comparable sales (comps)

The backbone of most appeals. You want recent, nearby sales of homes similar to yours — same neighborhood, comparable size, age, and condition — that closed for less than your FMV. A handful of clean comps is far more persuasive than a long list of loose ones. Closed sales carry weight; active listings carry very little.

A recent purchase price

If you bought the home recently in a normal sale, the price you paid is some of the strongest possible evidence of its market value. An open-market transaction is, almost by definition, what the home is worth. If the county's FMV sits well above what you just paid, that gap is your case. (If you just closed, read our new-homeowner guide — the timing matters.)

Property record errors

Pull your property record card from the county and check every detail. If they have you down for 2,800 square feet and you have 2,400, or a finished basement you don't have, that's a factual error the county must correct. These can be the cleanest wins of all because they're not a matter of opinion.

Condition and photos

Dated photos showing deferred maintenance, a failing roof, foundation issues, or other problems that depress value can support a lower FMV — especially when the county's records assume the home is in better shape than it is.

Step 5 — File your appeal

You file your appeal with the Fulton County Board of Assessors, in writing, before your deadline. Fulton County accepts appeals online, by mail, and in person; filing online is generally fastest and gives you a timestamp. Your appeal is your formal notice that you disagree with the FMV — it does not have to contain every shred of evidence on day one.

When you file, Georgia law (OCGA § 48-5-311) lets you choose how you want an unresolved appeal to be heard. Your options:

• Board of Equalization (BOE) — a panel of trained citizens. This is the most common route and has no filing fee. Good for value and uniformity disputes.
• Hearing officer — a certified appraiser, generally available for higher-value or non-homestead properties.
• Binding arbitration — where each side submits an appraisal; useful in some cases but it has cost and procedural requirements.

State your opinion of value on the form (what you believe the FMV should be) and keep a copy of everything you submit.

Step 6 — The Board of Assessors' first review

After you file, the Board of Assessors reviews your appeal. Sometimes they'll agree and send you a revised, lower value — and if that revised number works for you, you can accept it and you're done. If they don't change the value, or change it by less than you think is fair, the appeal moves forward to the hearing route you selected (usually the BOE).

Step 7 — The Board of Equalization (BOE) hearing

If your appeal isn't resolved on paper, you get a hearing before the Board of Equalization. This is less formal than a courtroom. You (or your representative) present your evidence — your comps, your purchase price, your corrected square footage — and the county's appraiser presents theirs. The three-member board then decides on a value.

A few things worth knowing:

• You can represent yourself, or have someone represent you. Under OCGA § 48-5-311(e)(6)(A), a non-attorney may represent a taxpayer before the BOE — including for a fee. A Georgia Court of Appeals decision, Dickey v. Fulton County Board of Tax Assessors (2015), confirmed this is not the unauthorized practice of law. (Superior Court is different — that requires a licensed attorney.)
• Bring organized, concise evidence. The board sees a lot of cases; a tight, well-documented argument lands better than a sprawling one.
• Be specific about the value you're asking for and why the data supports it.

Step 8 — The outcome (and the three-year payoff)

The BOE issues a decision with a value. If you win a reduction, your tax bill for the year is recalculated on the lower number. If you disagree with the BOE's decision, you can appeal further — to Superior Court within 30 days (where you'll need an attorney).

Here's the part many homeowners don't realize: a win usually isn't a one-year discount. Under Georgia's 299(c) value freeze (OCGA § 48-5-299(c)), after a successful appeal the county generally cannot raise your assessed value for the appeal year plus the next two years — a three-year freeze (barring substantial additions or improvements). One fight, three years of a lower bill. We cover this in depth in our guide to the Georgia 3-year property tax freeze.

Should you hire help, or do it yourself?

Plenty of homeowners successfully appeal on their own, especially when the case is a clean property-record error or an obvious purchase-price gap. It's a real, accessible right. If you go that route, the steps above are the whole playbook.

Where representation earns its keep is in the gray cases: pulling and weighting the right comps, knowing what the BOE responds to, and handling the filing and hearing so you don't have to. At Tax Appeal HQ we work on contingency — no win, no fee — which is also why we only take cases we believe we can win. A weak appeal costs us, not you, so we have every reason to be straight with you.
