Can my property tax go up if I appeal?

Losing at the Board of Equalization cannot raise your value, with one exception. Under O.C.G.A. § 48-5-311(e)(9), the Board of Equalization, a hearing officer, or an arbitrator can lower your value but cannot raise it above the value the county assessors set. The exception is a value already frozen by an earlier appeal: on an appeal filed while that freeze is in effect, the Board is not capped and could raise the value. That limit applies to the deciding body; the county assessors can still make changes or corrections to your value when they review your appeal.

Union City stretches along the I-85 corridor in south Fulton County, just southwest of Hartsfield-Jackson, and much of its workforce is tied to the airport, warehousing, and logistics jobs that cluster around it. With about 27,728 residents, it is one of south Fulton's larger cities, and its housing is priced for working families: the median home is worth about $245,600, roughly 46% below the Fulton County median of $458,800. That is the core tension of being an affordable city inside an expensive county. Across Fulton County, home values range from about $286,572 at the 25th percentile to $735,809 at the 75th, so the typical Union City house is worth less than the county's 25th percentile home, and valuation models tuned to Fulton's broader market tend to run high at the affordable end of the range. The burden lands hard here. Fulton's effective rate is about 1.42%, and with a median household income of $49,549, the typical Union City homeowner already gives up about 4% of household income to property taxes, an unusually heavy share. An assessment even 10% too high deepens that strain, and it repeats, because this year's value becomes the starting point for next year's. It costs nothing to set your notice against actual sales on your street. If the number does not hold up, you can appeal. Georgia law sets the appeal deadline at 45 days from the date of your assessment notice. The date printed on your notice controls. Confirm with your county before you file.

Is your Union City property tax assessment too high?

The median home in Union City is valued at $245,600, and the typical homeowner pays about $1,996 per year in property tax (Census ACS 2024), based on Fulton County's 3.553% combined millage applied to 40% of fair market value after exemptions. That means the typical Union City homeowner spends 4.03% of household income on property taxes alone. Even though Union City home values fall below the Fulton County average, the tax burden here is significant relative to household income. A lower home value does not mean your assessment is automatically correct. Overassessments happen at every price point, and correcting one can meaningfully reduce your annual bill. At $245,600, Union City home values are 46% below the Fulton County median, 44% above Georgia's statewide median of $170,200, 22% below the national median of $318,000.

A 10% reduction on the median Union City home ($245,600 down by $24,560) would save approximately $349 per year, or $1,047 over three years (estimated, subject to the statutory exceptions) with the 299c value freeze.
