Fulton County Property Tax Appeal: 2026 Deadlines & How to File
Updated June 2026
Fulton County homeowners have 45 days from their assessment notice to appeal property taxes — with assessments mailed in August, the deadline typically falls in October 2026. Georgia assesses residential property at 40% of fair market value. Fulton County encompasses Atlanta and its suburbs, and property values here make over-assessment costly. Check if your Fulton County home is over-assessed now.
Fulton County Assessment Overview
Fulton County is Georgia's largest county by population and home to Atlanta, Sandy Springs, Alpharetta, and Roswell. Georgia law requires residential property to be assessed at 40% of fair market value. To find your implied market value, multiply your assessed value by 2.5. See our Fulton County data page for current tax rates and reassessment schedules.

In Georgia, the appeal deadline is 45 days from the date your assessment notice is mailed. Fulton County mails assessment notices in August, making the 2026 appeal deadline fall in late September or October. Check your notice for the exact deadline date printed on it.

How to File a Fulton County Property Tax Appeal
Fulton County property tax appeals are filed online through the Fulton County Board of Assessors portal. Filing is free and you do not need an attorney. Have your parcel ID from your assessment notice or tax bill ready.
Step 1: File an Appeal of Assessment
File online at the Fulton County Board of Assessors website within 45 days of your notice date. State your reason: market value, uniformity, or taxability. You may attach evidence at filing or present it at your Board of Equalization hearing.
Step 2: Board of Equalization Hearing
Your appeal is heard by the Fulton County Board of Equalization, a panel of independent citizens trained in property valuation. Bring comparable sales data, property photos, and any record errors. The BOE issues its written decision within a few weeks of the hearing.
Step 3: Superior Court (if needed)
If the BOE decision does not provide sufficient relief, you can appeal to Fulton County Superior Court within 30 days. Most residential cases resolve at the BOE level without court.
Evidence for a Fulton County Appeal
Fulton County appeals are won with comparable sales evidence. Remember: your assessed value should be 40% of market value, so your implied market value = assessed value x 2.5.
1. Comparable Sales
Find 3-5 recent arm's-length sales of similar homes sold within the prior 12 months. Look for homes in the same neighborhood, similar square footage, age, and condition. Your comparable homes' implied market value should be lower than yours. See our comparable sales guide.
2. Uniformity Argument
Georgia requires uniform assessment. If neighboring homes of similar size and condition are assessed lower, document the discrepancy using Fulton County public records.
3. Property Record Errors
Review your property characteristics in the county database. Errors in square footage, bedroom/bathroom count, or property classification can cause significant over-assessment.
