Is my property over-assessed in Fulton County?
You're over-assessed when the County's value is higher than what your home would actually sell for — and then you're over-paying every year until you appeal. Georgia appeals are due 45 days after the county mails the Annual Notice of Assessment (typically late spring), per O.C.G.A. §48-5-311. The date is printed on your notice.
Honest null: Fulton County is in a non-disclosure state — sale prices aren't public — so no service (including us) can prove your over-assessment from a sale comparison. Instead, argue from comparable assessed values (the equity argument) and any independent appraisal. The deadline above still applies and is the thing not to miss.
How to appeal your Fulton County assessment — and who files it for you
Pull your current assessed value from the Fulton County assessor portal.
Find your market value — a recent sale of your home, or comparable nearby sales.
If the County's number is higher, file an appeal with the County Board of Tax Assessors → Board of Equalization by 45 days after your Annual Notice of Assessment.
Present your comparables (and any appraisal) at the hearing.
Most owners who win use a contingency property-tax appeal firm — it costs nothing unless they cut your bill, then takes a share of the first-year saving. About 95% of over-assessed owners never appeal, so the saving is usually left on the table.
What is the Fulton County appeal deadline this year?

I got a reassessment notice — what now?
It's the County's new market-value opinion and the start of your appeal window. Check it; appeal by 45 days after your Annual Notice of Assessment if it over-states your home's value.
Will appealing raise my taxes?
In most jurisdictions an appeal can only confirm or lower your assessment for that cycle — but confirm the rules with the County Board of Tax Assessors → Board of Equalization before filing.
