Cobb County Homestead Exemption Explained
Property taxes are one of the highest ongoing costs of owning a home in Marietta and across Cobb County. If this is your primary residence, a homestead exemption can lower your bill, sometimes by a meaningful amount. This guide breaks it all down with local context, practical steps, and simple examples so you know what to do next.
What is a Homestead Exemption?
A homestead exemption reduces the taxable assessed value of your primary residence. In Georgia, homes are commonly assessed at a percentage of fair market value. Any approved homestead exemption is subtracted from that assessed value. The county, city, and school millage rates then apply to the reduced amount, which lowers your annual tax bill.
The exemption must be in place for the tax year when the home is your primary residence as of January 1. So occupancy and ownership on January 1 are key for eligibility.
