What to check on your notice
The typical Columbia County home gained 1.3% in the year to January 2026. A notice that rose far more than that, or a value above what similar homes nearby actually sold for, is the usual starting point for an appeal.
Keep the state's limits in mind: Statewide floating homestead exemption from HB 581: your homestead's taxable assessed value can rise only by the annual inflation rate, set by the Department of Revenue, unless your county, city, or school district opted out. The inflation index first applies for the 2026 digest year. Assessed value is 40% of fair market value.
How a Georgia appeal works
Values in Columbia County are set by the local county board of tax assessors, and the appeal starts there. The rules below apply statewide; your notice has the exact dates and office for your property.
| Who sets the value | County board of tax assessors. Each county has a Board of Tax Assessors that sets fair market value. Appeals go first to that board, not to the state Department of Revenue. |
|---|---|
| Valuation date | January 1 |
| Your notice | Annual Notice of Assessment |
| Deadline | 45 days from the date the assessment notice was mailed. Mailing dates vary by county, so the deadline does too. |
| First step | File Form PT-311A with the county Board of Tax Assessors and choose an appeal path: the county Board of Equalization (a panel of three local citizens), a hearing officer, or arbitration. The assessors review first and may change the value, which gives you 30 days to appeal again. |
| If you still disagree | Superior court within 30 days of the decision from the Board of Equalization, hearing officer, or arbitrator. Taxes must be paid before the court will consider the case. |
| Form | Form PT-311A, Appeal of Assessment |
| Fee | The DOR guidance lists no filing fee for the Board of Equalization path. In arbitration the loser pays the arbitrator fees, based on whose value is closer to fair market value. |
Reading this in fall 2026? Most counties mailed 2026 notices in spring or summer, so the 45-day window has closed for nearly everyone. A few counties mail late, so check the mailing date on any 2026 notice you hold. Otherwise your next realistic chance is the 2027 notice, mailed in spring or summer 2027 for January 1, 2027 values. Watch your mail and count 45 days from the date on the notice, not from when you open it.
- Hearing officers are available only for non-homestead real property valued over $500,000.
- Whether you get the floating homestead cap depends on whether your local governments opted out of HB 581, so check with your county.
- You can apply for a homestead exemption in the same 45-day window as your appeal.

Building a Columbia County case
Averages explain why a case might work. The decision turns on evidence about one property. Columbia County is part of the Augusta-Richmond County metro, but your evidence should be local. Sales a few streets away usually beat sales across the metro.
- Gather comparable sales near January 1 of the tax year and the county's own property record card.
- Arbitration requires submitting a certified appraisal within the 45 days, so budget for an appraisal if you choose it.
- If the final value on a court appeal is 85% or less of the county board's value, you may recover court costs and attorney's fees.
- State on PT-311A which appeal method you want, since you must choose when filing.
