# Last Chance: Fulton County Property Tax Appeal Deadline Is Approaching
Fulton County assessment notices are expected to arrive in mid-June 2026, and if the past five years are any indication, your estimated Fulton County property tax appeal deadline 2026 is around August 1. Georgia law sets the appeal deadline at 45 days from the date printed on your notice, and that is your window to decide whether to challenge the county's valuation of your home. In 2025, residential assessments rose 5.9% countywide while actual sale prices rose only 3.7% per Georgia MLS data. The Board of Assessors' own figures show that 41% of residential properties were overvalued. Over 30,000 appeals were filed in 2023 alone. If your notice looks too high, you are probably right. But the window to do something about it is narrow, and it is already open. The date printed on your notice controls. Confirm with your county before you file.
Georgia law requires all property to be assessed at 40% of its fair market value. Your county does not tax you on what your home is worth. it taxes you on 40% of that number, called the assessed value. If your county says your home is worth $400,000, your assessed value is $160,000. That $160,000 is what the millage rate applies to when calculating your tax bill. This ratio is set by state statute (O.C.G.A. 48-5-7) and applies uniformly across all 159 Georgia counties.
Your Annual Notice of Assessment arrives by mail from your county Board of Tax Assessors. It is not a tax bill. it is the county's estimate of your property's fair market value as of January 1 of the current year. The notice shows three key numbers:
The notice also prints the date it was issued. That date starts your appeal clock. Check the property details carefully. Errors in square footage, lot size, bedroom/bathroom count, or condition rating are common and can inflate your assessed value.
Before filing an appeal, run a quick sanity check to see whether the county's number is actually wrong. or just uncomfortable.
Also check the assessor's property card for errors. incorrect square footage, wrong lot size, inaccurate bedroom/bathroom count, or a condition rating that does not match your home. These mistakes are more common than most homeowners realize. The National Taxpayers Union Foundation found that incorrect square footage appears in roughly 18% of assessments. One data entry error can inflate your tax bill for years if nobody catches it.
Georgia law sets the deadline to file a written appeal at 45 days from the date on your Notice of Assessment. The deadline runs from the date printed on the notice itself, not from the day you receive it. The date printed on your notice controls. Confirm with your county before you file.
If your Fulton County notice is dated June 17, your estimated deadline would be August 1. Based on five consecutive years of data (2021-2025), Fulton County notices have consistently been mailed in mid-June, with deadlines falling in late July to early August. The exact deadline is printed on your notice, so do not assume a date. Confirm with your county before you file.
The pattern is clear: expect your notice in mid-June and your deadline in late July or early August. But do not rely on the pattern alone. Check fultonassessor.org for your notice as soon as assessment season begins. the online version is typically available before the paper copy arrives. The day that notice is dated, your clock starts running whether or not you have opened the envelope.

The portal opens after notices are mailed. File 2-3 days before the deadline to avoid last-minute portal slowdowns or technical issues. Screenshot your confirmation page as proof of filing.
Send your completed PT-311A form to:
Fulton County Board of Assessors 141 Pryor Street, Suite 1018 Atlanta, GA 30303
Your appeal is deemed filed as of the USPS postmark date, not the date it arrives. Use certified mail or USPS statutory overnight delivery for proof. Do not use a home postage meter. metered mail stamps may not be accepted as a valid postmark. Go to the post office counter.

Email and fax filings are not accepted.
The strongest evidence in a Fulton County property tax appeal is comparable sales data: recent sales of similar homes that demonstrate your property's actual market value. The board is not interested in opinions about your tax bill being too high. They want data showing the county's fair market value estimate is wrong.
Focus on finding 3-5 properties that sold in 2025 (for a 2026 appeal) within your neighborhood or subdivision. Look for homes with square footage within 10-15% of yours, similar lot size, and comparable condition. Present them in a price-per-square-foot analysis. If your comps show an average of $180 per square foot and the county assessed your home at $210 per square foot, you have a clear, data-driven argument that is hard for the board to dismiss.
Property data for Fulton County is available at fultonassessor.org or through the county's online property search tool. You can also check Zillow, Redfin, or Georgia MLS records for recent transactions in your area.
Do not overlook the assessor's property card. If the county has your square footage wrong by even 100 square feet, that error alone can account for a $15,000-$25,000 overvaluation. Correcting data errors is sometimes the easiest path to a reduction.

AppealAlly's Full-Service Appeal handles your appeal as your agent (filing, evidence, case management, and deadline monitoring).
The Board of Equalization, a hearing officer, or an arbitrator can lower your value but cannot raise it above what the county assessors set (O.C.G.A. § 48-5-311(e)(9)), except on an appeal filed while a 299(c) freeze from an earlier appeal is in effect. You should not let this possibility stop you from filing when you have solid comparable sales supporting a lower number. At the BOE level, the overwhelming majority of outcomes are either a reduction or no change.
No. For most residential property tax appeals in Georgia, you do not need a lawyer. The Board of Equalization process is specifically designed for homeowners to represent themselves. If you have 3-5 strong comparable sales and can present your case clearly in a 10-15 minute hearing, you are well-equipped to handle it on your own. Consider professional help if your property is valued above $500,000, you are considering arbitration (which requires a certified appraisal), or your case may reach Superior Court. For a straightforward residential appeal based on comparable sales, self-representation is the norm. and statewide data shows that homeowners who show up with evidence win the majority of the time.
If you miss the appeal deadline, you cannot appeal your property tax assessment for the current tax year. You must wait until next year's assessment notice arrives and file by the deadline on that notice.
To avoid this: check fultonassessor.org for your notice as soon as assessment season begins, sign up for electronic notice delivery if available, and set a calendar reminder the day your notice is posted. Do not rely on mail delivery alone. postal delays in metro Atlanta have caused homeowners to miss deadlines in past years. The estimated Fulton County property tax appeal deadline 2026 is around August 1, but your specific deadline depends entirely on the date printed on your notice. Confirm with your county before you file.
