Peachtree Corners was planned around technology before that was fashionable, growing up in the 1970s around Technology Park in the southwest corner of Gwinnett County and incorporating as a city only in 2012. Its neighborhoods along the Chattahoochee River include some of Gwinnett's priciest housing: the median home is valued near $484,700, about 27 percent over the county median of $380,900. What stands out in the data, though, is the burden. With median household income at $82,139, the typical Peachtree Corners homeowner puts about 5.4 percent of income toward property taxes, a strikingly high share for a suburb, and higher than in many metro cities with far more expensive houses. Gwinnett's effective tax rate sits around 1.4 percent, so the assessed value on your annual notice does most of the work in determining what you owe. That value comes from county mass-appraisal models built to handle everything from starter townhomes to riverfront estates, and across Gwinnett County home values run from roughly $289,831 at the 25th percentile to $487,646 at the 75th. A median Peachtree Corners house already sits near the top of that range, which is exactly where uniform models drift furthest from what a specific property would actually bring on the market. Comparing your assessment against recent sales on your own street is the fastest reality check available, and if the number looks inflated, 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.

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.
