Appeals are filed with the Henry County Board of Assessors, not at the city level. File a PT-311A form within 45 days of your assessment notice.
How much of my income goes to property taxes in Locust Grove?
At the median, Locust Grove homeowners pay 4.04% of their household income ($75,083/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
How do Locust Grove property taxes compare to Heron Bay?
Heron Bay leads Henry County with a median home value of $393,000, compared to Locust Grove's $307,300. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Locust Grove property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Locust Grove's median home ($307,300), the assessed value is $122,920. Multiply by Henry County's millage rate of 3.368% to get your annual bill. Many Locust Grove 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 Locust Grove?
Yes. Even a $134 per year overcharge (from a $10,000 overvaluation at Henry County's 3.368% rate) adds up to $402 over three years with the 299c freeze. The appeal is free to file and there is no risk of your assessment increasing.
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.
