📊 Calculating Your Property Taxes in Cobb County
Your property tax bill is calculated by taking your property's assessed value (which is 40% of the Fair Market Value for residential property in Georgia, minus any applicable homestead exemptions) and multiplying it by the total millage rate.
Formula:
-
Assessed Value = Fair Market Value × 0.40 – Homestead Exemptions (if any)
-
Property Tax = Assessed Value × (Total Millage Rate ÷ 1000)
💡 Example Calculation for Cobb County
Suppose your Cobb County home’s Fair Market Value is $400,000, and you qualify for a $10,000 homestead exemption. The total millage rate in your area is 30 mills.
-
Assessed Value = ($400,000 × 0.40) – $10,000 = $160,000 – $10,000 = $150,000
-
Property Tax = $150,000 × 0.030 = $4,500
🔍 Influence of Millage Rates on Your Cobb County Property Taxes
-
📈 Higher millage rates mean higher taxes: Even if your assessed value stays the same, an increase in millage rates results in a higher tax bill.
-
📉 Lower millage rates mean lower taxes: Decreases in millage rates reduce your tax bill, assuming your assessed value remains constant.
-
🗺️ Millage rates vary across Cobb County: Properties inside incorporated cities often pay additional city millage, resulting in different total millage rates compared to unincorporated areas.
-
🏫 School funding is a major factor: A large portion of your tax bill goes to the Cobb County School District, so their millage rate decisions heavily influence your total tax.
❗ Why Understanding Millage Rates Matters for Your Cobb County Appeal
While your property tax appeal focuses on contesting the assessed value of your property, understanding millage rates helps you comprehend how a reduction in value translates to tax savings.
-
⚖️ Over-assessment amplifies your tax bill: If your property is overvalued, the millage rate multiplies this to increase your taxes. Lowering your assessed value via appeal reduces your tax proportionally.
-
🚫 Millage rates themselves are not appealable: Millage rates are set by elected or appointed taxing authorities and cannot be challenged through the assessment appeal process.
📌 Summary
Understanding how millage rates are set and applied in Cobb County, Georgia, gives you a clear picture of how your property tax is computed and the importance of your property's assessed value.
