Appeals are filed with the Spalding County Board of Assessors, not at the city level. File a PT-311A form within 45 days of your assessment notice.
Are Experiment homes undervalued compared to Spalding County?
Experiment's lower median does not mean the county's assessment of your specific home is correct. Overassessments happen at every price point. Compare your assessed value per square foot to actual recent sales of similar homes nearby.
How is my Experiment property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Experiment's median home ($137,500), the assessed value is $55,000. Multiply by Spalding County's millage rate of 3.581% to get your annual bill. Many Experiment homeowners find that assessed values have climbed faster than actual sale prices. Comparing your value to 3-5 recent sales of similar homes is the quickest way to spot an overassessment.
Is it worth appealing a small overvaluation in Experiment?
Yes. Even a $143 per year overcharge (from a $10,000 overvaluation at Spalding County's 3.581% rate) adds up to $429 over three years with the 299c freeze. The appeal is free to file and there is no risk of your assessment increasing.
Can I appeal if I just bought my Experiment home?
Yes. If you paid less than the county's assessed fair market value, your purchase price is strong evidence of overassessment. If you paid more, the county may eventually reassess upward -- but they cannot do so just because you appealed. Either way, you should compare your assessed value to what similar nearby homes actually sold for.
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.
