Twenty years ago Grayson was a crossroads town in eastern Gwinnett County; today it is one of the county's most sought after addresses, a small city of about 4,858 people where new subdivisions and a well regarded school cluster pulled home values well past the county norm. The median home in Grayson is now worth about $477,500, roughly 25% above the Gwinnett County median of $380,900. Put that against the county's overall range, which runs from about $289,831 at the 25th percentile to $487,646 at the 75th, and the typical Grayson home is brushing the top quarter of the entire county. Gwinnett's effective property tax rate is about 1.4%, and the typical Grayson household, earning a median of $131,293, commits around 3.3% of its income to property taxes, a meaningful line item even in a comfortable budget. Rapid appreciation created that position, and rapid appreciation is also what strains assessment accuracy: when the assessor's office revalues a fast moving market, homes that look similar on paper get similar values, whether or not one backs to a busy road, needs a roof, or was last updated when the subdivision was built. The gap between a defensible value and an inflated one is often five figures here, which makes the annual notice worth more than a glance.

Is your Grayson property tax assessment too high?
The median home in Grayson is valued at $477,500, and the typical homeowner pays about $4,378 per year in property tax (Census ACS 2024), based on Gwinnett County's 3.506% combined millage applied to 40% of fair market value after exemptions. That means the typical Grayson homeowner spends 3.33% of household income on property taxes alone. Grayson combines higher-than-average home values with a heavy tax burden. If your home is overassessed by even 10%, the cost adds up fast. Higher home values mean a larger tax bill and a bigger payoff from a successful appeal. At $477,500, Grayson home values are 25% above the Gwinnett County median, 180% above Georgia's statewide median of $170,200, 50% above the national median of $318,000.
How does Grayson compare to other Gwinnett County cities?
Peachtree Corners leads Gwinnett County in home values, but your individual assessment could still be too high regardless of where Grayson falls in the county ranking.
What evidence matters for Grayson appeals?
In a mid-size city like Grayson, you should be able to find 3-5 comparable sales within Gwinnett County. Look for homes that sold in the last 12 months with similar square footage, age, and condition. If local sales are limited, expand your search to neighboring areas within the county. For the full evidence strategy, exemption details, and step-by-step filing instructions, see our Gwinnett County Property Tax Guide.
How much can you save in Grayson?
Based on a combined tax rate of 3.506%. 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 Grayson home ($477,500 down by $47,750) would save approximately $670 per year, or $2,010 over three years (estimated, subject to the statutory exceptions) with the 299c value freeze.
At 3.33% of household income, even a modest reduction in your assessed value makes a real difference in your annual budget.

Frequently Asked Questions
Is my Grayson property tax too high?
The median annual property tax bill in Grayson is $4,378 (Census ACS). If your assessed value is higher than what your home would actually sell for, you are paying more than that. Compare your assessed value to recent sales of comparable homes nearby.
Who do I contact to appeal my Grayson property tax?

How much of my income goes to property taxes in Grayson?
At the median, Grayson homeowners pay 3.33% of their household income ($131,293/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
Why are Grayson home values higher than the Gwinnett County average?
Grayson'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 $669 per year in excess taxes.
How do Grayson property taxes compare to Peachtree Corners?
Peachtree Corners leads Gwinnett County with a median home value of $484,700, compared to Grayson's $477,500. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Grayson property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Grayson's median home ($477,500), the assessed value is $191,000. Multiply by Gwinnett County's millage rate of 3.506% to get your annual bill. Many Grayson 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 Grayson?
Yes. Even a $140 per year overcharge (from a $10,000 overvaluation at Gwinnett County's 3.506% rate) adds up to $420 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.
