Frequently Asked Questions
Is my Lithonia property tax too high?
The median annual property tax bill in Lithonia is $2,617. Using DeKalb County's millage rate of 4.379%, the computed tax on the median home ($223,000) is approximately $3,906. If your assessed value is higher than what your home would actually sell for, you are overpaying.
Who do I contact to appeal my Lithonia property tax?
Appeals are filed with the DeKalb County Board of Assessors, not at the city level. File a PT-311A form within 45 days of your assessment notice.
How much of my income goes to property taxes in Lithonia?
At the median, Lithonia homeowners pay 4.24% of their household income ($61,713/year) in property taxes. That is a significant burden -- a successful appeal directly increases your take-home.
Are Lithonia homes undervalued compared to DeKalb County?
Lithonia's lower median does not mean the county's assessment of your specific home is correct. Overassessments happen at every price point. Compare your assessed value per square foot to actual recent sales of similar homes nearby.
How do Lithonia property taxes compare to Brookhaven?
Brookhaven leads DeKalb County with a median home value of $692,700, compared to Lithonia's $223,000. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Lithonia property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Lithonia's median home ($223,000), the assessed value is $89,200. Multiply by DeKalb County's millage rate of 4.379% to get your annual bill. In smaller communities like Lithonia, 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 Lithonia?
In smaller communities, finding 3-5 recent sales of similar homes can be difficult. Expand your search to other parts of DeKalb 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.
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.
