Key Takeaways
You have 45 days from the date on your Fulton County Annual Notice of Assessment to file an appeal; miss it and you wait a full year.
In Georgia your assessed value equals 40% of the county's appraised fair market value, so an inflated appraisal inflates everything downstream.
A successful appeal triggers Georgia's 299(c) freeze, locking your reduced value in place for three tax years.
Georgia is one of the few states where a poorly supported appeal can raise your value, so evidence and comparable sales matter.
Most Georgia homeowners never appeal, so a well-prepared case is often the difference between overpaying and locking in savings.
Introduction
If you own a home in Fulton County, your tax bill has likely climbed alongside metro-Atlanta values. Yet our Georgia property tax homeowner survey found that 81% of Georgia homeowners have never appealed, and 51% don't know they have the right.
A Fulton County property tax appeal is your formal request to lower the county's value on your home, and it is often the fastest way to stop overpaying. This Ownwell guide walks you through the deadline, the evidence that wins, the risk unique to Georgia, and the 299(c) freeze that protects your savings.
How Fulton County Sets Your Value (and Why It's Often Too High)
Everything on your bill starts with one number: your appraised fair market value (FMV). In Georgia, your assessed value equals 40% of that FMV, so a $400,000 appraisal produces a $160,000 assessed value before any exemptions.
The Fulton County Board of Assessors (BOA) sets that FMV through mass appraisal, valuing thousands of homes at once and mailing Annual Notices of Assessment in the late spring. Mass appraisal is built for volume, not accuracy on any single property.
That is where errors creep in. The model rarely sees your deferred maintenance, a cracked foundation, an outdated interior, or a smaller footprint than the county has on file. After handling more than a million appeals, we've found the most common overcharge starts with an inflated fair market value.
Your combined millage rate, blending county, school, and city levies, then turns that value into a dollar figure. For the full rate breakdown and calculation detail, see our Fulton County property tax rates guide rather than re-deriving it here.
Know Your Deadline: The 45-Day Window
Your right to appeal has a hard expiration date. You have 45 days from the date printed on your Annual Notice of Assessment, not the date you open the envelope, to file.
Fulton mailed 2026 notices in mid-June, and the Fulton County 2026 appeal deadline is July 31, 2026. Confirm your exact date against the notice itself and our Fulton County property tax page before you file, because a late or after-postmark appeal is rejected outright.
One clarification saves confusion: you are appealing the county's value, not the estimated tax printed on the notice. Lower the value, and the tax follows.
If your notice arrived this month, treat the countdown as active. Every day you wait is a day less to pull comparable sales and document your home's condition.
How to File Your Fulton County Property Tax Appeal
You can file your appeal in one of three ways:
Online: Submit through the Fulton County Board of Assessors portal at fultonassessor.org, the fastest and most trackable option.
By mail: Send your appeal so it is postmarked on or before your deadline.
In person: File at 235 Peachtree St. NE, Suite 1200, in downtown Atlanta.
File your appeal via Form PT-311A, the official Georgia Department of Revenue appeal form. Have your parcel ID, property address, your own value estimate as of Jan. 1, your chosen appeal method, and your temporary-billing election ready before you start.
That billing election matters. During an active appeal, you can be billed at 85% or 100% of the value in dispute; you pay a temporary bill either way, and the county trues it up once you resolve.
When you file, you also choose how your appeal will be resolved. The three routes differ in cost and fit:
Resolution Route | Best For | Cost |
|---|---|---|
Board of Equalization (BOE) | Most homeowners appealing value or uniformity | Free |
Hearing Officer | Non-homestead and commercial property valued over $500,000 | Filing cost applies |
Arbitration | Owners wanting a binding decision from a certified appraiser | Fee, plus appraisal cost |
We file Form PT-311A and the Letter of Authorization for you, so you never navigate the portal or the deadline alone.
How Much Are You Over Paying?
What Evidence Wins a Fulton County Appeal
Filing is easy; winning takes proof. After handling more than a million appeals, we've found the difference usually comes down to three to five well-chosen comparable sales.
Strong comparable sales are homes similar to yours in size, age, and neighborhood that sold in the last six to 12 months. They tell the BOA what your property is actually worth, not what a mass-appraisal model guessed.
Next, check your property record card for errors. Overstated square footage, an extra bedroom or bathroom, wrong lot size, or a condition rating that ignores real wear all inflate your value, and correcting them is often the cleanest win.
Most homeowners appeal on one of two grounds recognized under Georgia law:
Value: The county's fair market value exceeds what your home would sell for.
Uniformity: Your home is assessed higher than comparable neighboring properties.
Support your case with dated photos of condition issues and written repair estimates. If you reach a Board of Equalization hearing, ground your presentation in Fulton-specific evidence: county comparable sales, your corrected record card, and the 299(c) freeze as your target outcome.
Logistics matter too. Bring four copies of your evidence to an in-person hearing, or submit your materials at least 48 hours before a virtual one.

The Risk Only Georgia Homeowners Face
Here is what most guides skip. Georgia is one of the few states where a failed or poorly supported appeal can raise your assessed value, because the BOA or BOE can respond to a weak case with a higher number.
That risk is largely invisible to homeowners. Our Georgia Property Tax Homeowner Survey found that 53% of Georgia homeowners don't know appealing can move their value in either direction.
This is exactly why reviewing your comparable sales before you file is not optional. If the market data points toward a higher value, filing an unsupported appeal can cost you.
We review current market data before filing every Georgia appeal, and we may decline to file when the evidence suggests your value could rise. Risk-managed filing protects you from turning a routine appeal into a larger bill.
The 299(c) Three-Year Freeze: What a Win Locks In
A successful appeal in Georgia does more than cut this year's bill. Under Georgia Code Section 48-5-299(c), an appeal that lowers your fair market value freezes your assessed value for three consecutive tax years, a protection detailed in our Georgia 299(c) freeze guide.
The freeze is one of the strongest tools in Georgia property tax, yet our Georgia Property Tax Homeowner Survey found that 57% of homeowners have never heard of it and only 13% understand how it works.
The timing is especially valuable now. Georgia's HOME Act, or Senate Bill 33, stands for the Homeownership Opportunity and Market Equalization Act. It makes the previous HB 581 floating homestead exemption — which caps how fast your homestead's taxable value can grow with inflation — mandatory statewide by 2027.
Winning your appeal before that cap takes broader effect resets your baseline lower, so the freeze and the HOME Act compound in your favor. When we secure a 299(c) freeze for you, a $20 fee applies on top of our standard contingency.
What a Successful Appeal Saves You
Percentages are abstract; dollars are not. Here is the Georgia math: appraised fair market value multiplied by 40% gives your assessed value; subtract any homestead exemption; then apply the combined millage rate to reach your annual bill.
Consider a metro-Atlanta home the county appraised at $440,000 when a well-supported appeal shows its fair value is $400,000, using Fulton's roughly 0.75% median effective rate.
*Note: because millage rates and exemptions vary by city and school district within Fulton, we estimate using the median effective rate (tax paid ÷ fair market value) applied directly to FMV, rather than walking through assessed value and a specific millage rate.
Line Item | Before Appeal | After Successful Appeal |
|---|---|---|
Appraised fair market value | $440,000 | $400,000 |
Assessed value (40% of FMV) | $176,000 | $160,000 |
Fulton effective tax rate | ~0.75% | ~0.75% |
Estimated annual tax bill | $3,300 | $3,000 |
Annual savings | $300 |
That $300 repeats each year the 299(c) freeze holds your value in place — roughly $900 over three years from one filing, assuming local millage rates stay flat. (The freeze locks your assessed value, not the tax rate, so your bill can still move if the county, school, or city raises its millage).
If you have a mortgage with an escrow account, the lower bill flows through as smaller monthly payments. If you own your home outright, you pay the county directly on the due date and pocket the difference.
Either way, remember the temporary bill during an active appeal must still be paid on time. Our guide on Georgia property tax bills during an appeal explains how that works.

Frequently Asked Questions
What is the deadline to appeal my property taxes in Fulton County?
You have 45 days from the date printed on your Annual Notice of Assessment, and the Fulton County 2026 appeal deadline is July 31, 2026. Miss that window, and you generally wait until the next tax year to appeal.
Can my assessed value go up if I appeal in Fulton County?
Yes. Georgia is one of the few states where a poorly supported appeal can lead the county to raise your value, which is why strong comparable sales matter before you file.
What evidence do I need for a Fulton County property tax appeal?
Three to five recent comparable sales of similar nearby homes are the strongest evidence. Support them with photos of condition issues, repair estimates, and any errors on your property record card.
Do I have to pay my tax bill while my appeal is pending?
Yes. You receive a temporary bill during an active appeal and must pay it on time, and the county adjusts the amount once your appeal is resolved.
How much is the Fulton County homestead exemption worth?
The basic homestead exemption reduces your taxable value, and additional county, senior, and school property tax exemptions can add to the savings. Amounts vary, so confirm which exemptions apply to your property with the county.
