Property TaxThe City of Kennesaw Finance Department is responsible for billing, collecting and disbursing city property taxes.  Taxes are generated on property values that are determined by the Cobb County Tax Assessor’s Office. Taxable property includes not only real estate, but also personal property; boats, airplanes and business assets. Cobb County is responsible for collecting the city taxes on motor vehicles, timber and mobile homes – the City of Kennesaw does not directly collect these. Taxes are billed or levied in the fall of each tax year for the period of January 1 through December 31 of that year. Annual property tax bills are mailed October 1 and are due by December 1. If you have not received your tax bill by the first week of October, please contact the Office of Property Tax.

The city provides a tax exemption for individuals aged 65 and older on their annual property taxes. To be eligible, residents must submit an exemption application along with a photocopy of their Georgia driver’s license or State ID. It is imperative to apply by April 1 to ensure the exemption for the upcoming tax year. Access the Senior Property Tax Exemption application form in the Document Center.

For any further inquiries, please reach out to the city’s Property Tax Administrator.
