Appeals are filed with the Fulton County Board of Assessors, not at the city level. File a PT-311A form within 45 days of your assessment notice.
Are Union City homes undervalued compared to Fulton County?
Union City'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 Union City property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Union City's median home ($245,600), the assessed value is $98,240. Multiply by Fulton County's millage rate of 3.553% to get your annual bill. In growing cities like Union City, reassessments often outpace actual market conditions -- compare your assessed value per square foot to recent closed sales within 1 mile of your home.
What evidence wins a property tax appeal in Union City?
The strongest evidence is 3-5 comparable sales -- homes similar to yours in size, age, and condition that sold recently for less than your assessed value. In Union City, there are typically enough recent sales to build a strong case. Focus on per-square-foot price comparisons and adjust for differences in lot size, condition, and amenities.
Can I appeal if I just bought my Union City 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.
