How Cobb County Assessment Records Affect Your Property Tax Bill
The Cobb Board of Tax Assessors places a fair and equalized value on taxable property. Under Georgia law, property is assessed at 40% of fair market value, and the tax estimate is generally calculated as: value × 40%, minus exemptions, multiplied by the millage rate.
100% value
The county’s estimate of what the property would sell for as of the valuation date.
40%
Georgia applies a 40% assessment ratio before exemptions and millage are applied.
45-day clock
If you disagree with the value, the appeal period runs from the assessment notice date.

Review homestead, school tax, disability or other exemption status. The 2026 notice guidance says if you are no longer eligible for homestead, you may need to report ineligibility before the appeal deadline to avoid tax, interest and penalty consequences.
How to Appeal a Cobb County Property Assessment

| Uniformity | Is the appraisal equitable compared with similar properties? | Similar homes with lower valuations, neighborhood comparisons. |
| Taxability | Whether the property should be taxable. | Ownership/use documents, legal basis, exemption documentation. |
| Exemption denial | Dispute over homestead, school tax, disability, Freeport or other exemption status. | Application, residency proof, age/disability documents, ownership date. |

Value, 40% assessment, exemptions, school taxes, bonds, fire and city millage can all affect the final bill.
Mableton may add local impact
If your property is inside a city, city millage or new local public-safety taxes can affect what you owe.
Search deeds after tax clues
Use parcel, owner and sale-date clues from the tax/assessor record to avoid broad deed-record searches.
