Heron Bay is not an old Georgia town at all but a master-planned golf community on the southern edge of Henry County near Locust Grove, where about 4,595 people live along fairways and lakes built out largely over the past two decades. Planned communities create a particular assessment problem worth understanding. The median Heron Bay home is worth around $393,000, about 25% above the Henry County median of $313,900, and the typical household earns $106,338, with property taxes absorbing roughly 3.4% of that income. Henry's effective tax rate runs about 1.35%, on the higher side for the southern metro, so valuation errors get amplified. Across Henry County, home values range from roughly $227,073 at the 25th percentile to $398,232 at the 75th, which puts the typical Heron Bay home near the top of the county's spread. Here is the catch with a community like this one. Homes inside a golf development look uniform on an assessor's spreadsheet, but their actual market values diverge sharply based on lot position, golf frontage, and finish level. A blanket rate per square foot will overvalue the homes without premium features while underpricing the ones with them, and if yours is on the wrong side of that math, the error repeats every year until someone challenges it.

Is your Heron Bay property tax assessment too high?
The median home in Heron Bay is valued at $393,000, and the typical homeowner pays about $3,558 per year in property tax (Census ACS 2024), based on Henry County's 3.368% combined millage applied to 40% of fair market value after exemptions.

At $393,000, Heron Bay home values are 25% above the Henry County median, 130% above Georgia's statewide median of $170,200, 23% above the national median of $318,000.

What evidence matters for Heron Bay appeals?

How much can you save in Heron Bay?
Based on a combined tax rate of 3.368%. Your actual rate may vary by tax district. Three-year figures are estimates and apply only if your value is reduced; you can then keep saving for up to three years, subject to the statutory exceptions.
A 10% reduction on the median Heron Bay home ($393,000 down by $39,300) would save approximately $529 per year, or $1,587 over three years (estimated, subject to the statutory exceptions) with the 299c value freeze.

How much of my income goes to property taxes in Heron Bay?
At the median, Heron Bay homeowners pay 3.35% of their household income ($106,338/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
Why are Heron Bay home values higher than the Henry County average?
Heron Bay's premium reflects demand driven by school quality, proximity to employment centers, and neighborhood amenities. Higher values mean a larger potential overassessment -- a 10% overvaluation costs approximately $529 per year in excess taxes.
How do Heron Bay property taxes compare to McDonough?
Heron Bay's median home value of $393,000 is higher than McDonough's $314,600. Higher values mean a larger tax bill and a bigger payoff from a successful appeal.
How is my Heron Bay property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Heron Bay's median home ($393,000), the assessed value is $157,200. Multiply by Henry County's millage rate of 3.368% to get your annual bill. Many Heron Bay 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 Heron Bay?
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 (estimated); if an appeal removes it, the 299c freeze can keep that saving for up to three years, subject to the statutory exceptions. The appeal is free to file, and the Board of Equalization cannot raise your value above the county assessors' figure, except on a value already frozen by an earlier appeal.
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.
