Fulton County Property Tax Appeal: Deadline, Process, and the 299(c) Freeze

Fulton County issued 2026 Annual Notices of Assessment in June, with a deadline of July 31, 2026 for most properties. If that date has already passed when you read this, mark your calendar for next June — the process resets annually and the county mails notices roughly the same week each year.

This guide covers the 2026 filing mechanics, the evidence that wins at the Board of Equalization, and the 299(c) three-year freeze that makes a successful appeal worth more than it looks in year one.

How Georgia property tax assessments work

Georgia assesses property at 40% of fair market value as of January 1 each year. That 40% figure is called the assessed value. Your tax bill multiplies assessed value (after exemptions) by the combined millage rate from the county, school district and city.

The Board of Tax Assessors (BTA) sets the value. The Board of Equalization (BOE) — a separate, independent panel of three citizens — hears your appeal if the BTA does not resolve it.

In Fulton County, 40% of a $431,200 median home is $172,480 assessed value. Apply the county General Fund rate of 8.87 mills and the county portion alone is $1,530. Add Atlanta Public Schools (~20.50 mills for APS-zone) and the city of Atlanta rate (~9.04 mills) and the total effective millage on a City of Atlanta property runs around 38.41 mills — $6,623 on that same median home before exemptions. The standard homestead exemption, plus Atlanta’s own exemption, cuts it meaningfully. The point: a $20,000 reduction in assessed value at a 38-mill rate is worth $760 a year. The 299(c) freeze stretches that over three years.

The 299(c) three-year freeze: why one appeal covers three tax years

Under O.C.G.A. § 48-5-299(c), when your appeal results in an actual reduction in assessed value, the county cannot raise that value during the next two years. The appeal year plus two more = three years of protection. That is what turns a single appeal win into three years of lower bills.

The “actual reduction” requirement matters. Under HB 581 (2024), a “no change” outcome no longer triggers the freeze. If you appeal, come with evidence that supports a lower number, not just an argument that the current value is debatable.

The two grounds for appeal in Fulton County

1. Value — fair market value as of January 1

The standard case: your property is worth less than the assessor’s number. You need three to five closed sales of similar properties, adjusted for size, age, condition and location, that support a lower value as of January 1. Pull them from the county records at fultonassessor.org or from a licensed appraiser. The BOE gives both sides 10–15 minutes. Short, clean, evidence-first.

2. Uniformity — your assessment is disproportionate

Georgia also allows an equity / uniformity appeal under O.C.G.A. § 48-5-299(c) — the argument that your property is assessed disproportionately high compared to similar properties. You do not have to prove fair market value is wrong. You only need to show your assessed value per square foot is higher than comparable parcels. Present comparable assessments (not sales) from the county records. This is a Georgia-specific argument; it does not exist in Florida, California or New Jersey. If you bring it, check the uniformity box on your PT-311A and choose the BOE route (not arbitration).

How to file in Fulton County

Step 1 — Request an informal review (optional but free)

Call the Fulton County Board of Assessors at 404-612-6440. Record errors — wrong square footage, wrong property class, nonexistent improvements — get fixed here fastest. The informal conversation does not extend the 45-day deadline.

Step 2 — File the PT-311A before July 31

File at fultonassessor.org (online, preferred), by mail to 235 Peachtree Street NE, Suite 1200, Atlanta, GA 30303, or in person at any of Fulton’s six Board of Assessors offices. Postmarked by the deadline is acceptable for mail. No fax or email. You must choose your appeal route on the form: BOE (most common), arbitration, or hearing officer. On PT-311A, check all grounds that apply: value, uniformity, taxability.

Step 3 — The Board of Assessors review

A staff appraiser reviews your appeal and may offer an amended value. If you accept, the appeal ends and the 299(c) freeze begins if the value was reduced. If you reject, your case is forwarded to the BOE.

Step 4 — Board of Equalization hearing

A three-citizen panel, appointed by the grand jury. You present your evidence (comps, photos, condition documentation). The county appraiser presents theirs. Each side gets 10–15 minutes. The board issues a written decision within 10 days, delivered by certified or registered mail.

Step 5 — Pay your tax bill while the appeal is pending

Georgia law requires you to pay the undisputed portion of your tax bill while an appeal is pending. Miss it and you risk penalties. The county issues a temporary bill based on the prior year’s assessment or 85% of the current assessment while the appeal is open.

What will not work here

• The wrong date. Georgia values property as of January 1. Sales after that date and damage after that date are next-year issues.
• Millage rates. The BOE hears value and uniformity. It does not set tax rates. Budget-hearing complaints go to the Board of Commissioners.
• “My bill went up too much.” A higher bill can mean a higher assessed value, a higher millage, a lost exemption, or all three. Identify the cause before deciding whether to appeal.
• Filing after the deadline. Georgia law does not extend the 45-day window. One day late means waiting until next year.

Who should appeal in Fulton County

• Anyone whose January 1 value looks higher than what the property would have sold for that day. The standard case.
• Owners who bought the property in the last two years. Your closing price is close to unanswerable evidence of fair market value.
• Owners whose assessed value per square foot is above the neighborhood median. Pull comparable assessments from the county records. If yours is higher, you have a uniformity case.
• Landlords and commercial owners. No homestead cap protection means every dollar of overassessment costs you. The equity argument is particularly strong on income-producing property where the assessor’s mass-appraisal model struggles with vacancy or condition.

If you would rather not build the comparable-sales analysis yourself, TaxDrop One runs your Fulton County property against public records and MLS-sourced sales, identifies whether you have a case, and delivers a filled PT-311A with the evidence packet for $129 per property per tax year. A licensed appraiser reviews every Georgia case before it goes out.
