Multiply by Gwinnett County's millage rate of 3.506% to get your annual bill. In smaller communities like Berkeley Lake, the county may rely on limited data to set your value. If your home is unique or the comparable sales used are a poor match, there is a good chance your assessment is off.
What if there are few comparable sales near Berkeley Lake?
In smaller communities, finding 3-5 recent sales of similar homes can be difficult. Expand your search to other parts of Gwinnett County -- the BOE panel understands limited inventory in small towns. Look for homes with similar square footage, lot size, and condition even if they are several miles away.
Why is my Berkeley Lake property tax bill so high?
The median tax bill in Berkeley Lake is $6,408 -- 345% above Georgia's statewide median of $1,439. This reflects both higher home values and Gwinnett County's combined millage rate. If your individual assessment is higher than what your home would actually sell for, you are paying even more than necessary.
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.
