How the tax is worked out
Think of the final bill as three ingredients: the assessed value of the property, the exemptions subtracted from it, and the combined rate of every district the property sits in. Cobb County's medians imply a derived rate of 0.69%; applied illustratively, a $400,000 home would owe about $2,740 a year, or around $228 a month spread evenly. Individual properties depart from the illustration in both directions.
Checking your assessment in Cobb County
If your bill looks wrong, work through these steps:
1. Get your property record card from the assessor and check the basics — living area, lot size, bedrooms, condition, and any exemptions you should have.
2. Compare your assessed value with recent sale prices of similar homes in Cobb County.
3. Talk to the assessor's office informally first; clear errors are often fixed without a hearing.
4. If needed, file a formal appeal with the local review board before the deadline on your assessment notice, with your evidence attached.
5. Keep paying the bill as issued while the appeal runs, unless your notice says otherwise — unpaid taxes accrue penalties regardless of an appeal.
