Columbia County has been one of Georgia's fastest-growing counties for over two decades, driven by families moving out of the Augusta metro for newer subdivisions and top-rated schools. That demand has pushed the median home value to roughly $305,300 — nearly double the statewide figure — and the typical annual tax bill runs about $2,515. If your home's assessed value jumped on your latest notice, this guide walks through how to evaluate whether an appeal makes sense and how to build a strong case.

How to Appeal Your Columbia County Assessment
Homeowners in Columbia County have 45 days from the date of the assessment notice from their assessment notice to file a property tax appeal using the PT-311A form.
Georgia gives you exactly 45 days from the date of the assessment notice to file a written appeal. This deadline is strictly enforced — one day late and you lose your right to appeal for the entire year. The deadline counts from the date printed on your notice, not from when you received it.
You can file by mail (certified mail recommended), online through the assessor's portal, or in person. When you file, you must choose an appeal path — the Board of Equalization (BOE) is recommended for most homeowners. For a full walkthrough of appeal paths, evidence strategies, and hearing preparation, see our Georgia Property Tax Appeal Guide.
Exemptions reduce your taxable assessed value before the millage rate is applied. All exemptions require a one-time application by April 1. You can apply for exemptions and file an appeal at the same time — they are separate processes.

Frequently Asked Questions
What is the deadline to appeal my Columbia County property tax assessment?
You have 45 days from the date of the assessment notice. The clock starts from the date printed on the notice, not when you receive it. File early — online portals in metro counties can experience heavy traffic near the deadline.
What form do I need to file a Columbia County appeal?
The PT-311A form from the Georgia Department of Revenue. You can file online, by mail (certified mail recommended), or in person at the Columbia County Board of Assessors.
Are Columbia County BOE hearings held virtually?
Most metro counties in Georgia now offer virtual hearings in addition to in-person options. Contact the Columbia County Board of Equalization to confirm. For virtual hearings, submit all evidence by email at least 48 hours in advance.
How long does the Columbia County appeal process take?
In metro counties, BOE hearing backlogs can stretch the process to 3-6 months from filing to decision. The Board of Assessors has up to 90 days to review your appeal before forwarding it to the BOE.
My home value jumped 20% or more — is that normal?
In fast-growing metro counties like Columbia, assessment increases of 15-25% have been common in recent years. However, a large increase does not mean the county's number is correct. Compare your assessed value per square foot to actual recent sales in your neighborhood.
Can my property tax go up if I appeal?
No. Georgia law (O.C.G.A. § 48-5-311) protects you: the county cannot raise your assessed value above what they originally set just because you filed an appeal. The Board of Equalization only rules on the disputed value. Worst case, your appeal is denied and you keep your current assessment — your taxes will not increase as a result of appealing.
