Georgia has one of the cleanest appeal deadlines in the country and one of the least forgiving. Forty-five days from the notice date, every parcel, every county. There is no rolling window, no discretionary extension, and no hardship exception — and Georgia courts have made clear that a late appeal does not get a merits review no matter how badly the property is over-assessed.
The difficulty is not understanding the rule. It is that the clock starts on a document you did not send, on a date you did not choose, delivered to whatever address the county has on file. This guide walks the full Georgia calendar for commercial property — from the Annual Notice of Assessment through the county board of tax assessors, the three appeal routes, and the Superior Court window that follows. EPTA represents commercial owners across Georgia, alongside Michigan, Indiana, Ohio, Pennsylvania, and Wisconsin.
The Notice Is the Trigger, Not the Tax Bill
Georgia's Annual Notice of Assessment is the operative document. It is not a bill and it asks for no payment, which is precisely why it gets set aside. It states the county's value for the year, an estimate of the taxes that value will produce, and the date that starts your 45 days. The tax bill itself arrives months later, long after the appeal window has closed.
The notice carries real substantive content beyond the deadline. Where the assessment increases significantly, the county must provide a plain-language explanation of the basis for the change and tell you that the records behind it are available for inspection at minimal cost. Those records are the cheapest evidence you will ever obtain in a Georgia appeal, and requesting them early frequently reveals the error — a wrong square footage, a stale income figure, a comparable that has nothing in common with your building.
