Frequently Asked Questions
Is my Austell property tax too high?
The median annual property tax bill in Austell is $1,405. Using Cobb County's millage rate of 3.015%, the computed tax on the median home ($284,900) is approximately $3,435. If your assessed value is higher than what your home would actually sell for, you are overpaying.
Who do I contact to appeal my Austell property tax?
Appeals are filed with the Cobb 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 Austell?
At the median, Austell homeowners pay 1.93% of their household income ($72,938/year) in property taxes. Reducing your assessment through an appeal lowers that share and increases your take-home.
Are Austell homes undervalued compared to Cobb County?
Austell'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 Austell property taxes compare to Smyrna?
Smyrna leads Cobb County with a median home value of $449,500, compared to Austell's $284,900. But a lower county ranking does not mean your individual home is correctly assessed -- overassessments happen at every price point.
How is my Austell property tax bill calculated?
Georgia taxes property at 40% of fair market value. For Austell's median home ($284,900), the assessed value is $113,960. Multiply by Cobb County's millage rate of 3.015% to get your annual bill. Many Austell 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 Austell?
Yes. Even a $120 per year overcharge (from a $10,000 overvaluation at Cobb County's 3.015% rate) adds up to $360 over three years with the 299c freeze. The appeal is free to file and there is no risk of your assessment increasing.
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.
