What homeowners need to know: The county advertised an increase relative to its rollback benchmark even while keeping the nominal general-fund rate unchanged. It also says eligible homesteaded parcels may see no change to the county M&O part of the bill if the owner has not made property improvements that change taxable value. Other levy components and school taxes require separate checks.

Quick answer: what is actually changing?
Cobb County adopted its 2026 millage and fiscal 2027 budget after July hearings. The county general-fund rate is 8.46 mills and the fire rate is 2.97 mills. Cumberland Special Services District II has a separate 2.45-mill rate where applicable, not a countywide charge.
How county rates can be flat while the notice says increase
Georgia law compares proposed revenue against a rollback rate after reassessments. Cobb advertised 4.07% above rollback in its county M&O notice even though the nominal M&O rate was not raised.
Why parcels differ
School districts, fire coverage, municipal boundaries and special-service districts affect the actual lines on a Cobb tax bill. The Cumberland rate is not charged to all Cobb County properties.
What the homestead freeze means
Cobb's official announcement says its floating homestead exemption protects eligible unchanged primary residences from an increase in COUNTY M&O tax when that rate stays flat. This does not promise the full tax bill is unchanged.
Paying or appealing
Use the county tax commissioner for billing and payment, and the county assessor for valuation and qualifying exemptions. Tax notices and deadlines should be confirmed against the specific parcel.

More homeowner questions
What does a Cobb County homestead exemption cover?
Homestead relief generally reduces taxable assessed value on qualifying primary residences, but the amount and levy categories affected depend on the specific exemption. Check Cobb County’s official eligibility requirements rather than assuming city, school and county portions all receive identical relief.
How do I appeal a Cobb County property assessment?
Review the annual assessment notice and file a valuation appeal with the Cobb County Board of Tax Assessors within the applicable notice deadline, generally 45 days. An appeal of value differs from objecting to a millage rate.
Why are Marietta property taxes different from an unincorporated Cobb address?
The city and special taxing-district components may differ in addition to county and school millage. Compare the property-tax district and applicable exemptions for each specific parcel.
