Whether you are a first-time homebuyer in Marietta or a long-time resident of Smyrna, understanding property taxes in Cobb County is essential. These taxes play a major role in funding schools, public safety, and infrastructure, while also impacting your overall housing costs. This guide breaks down everything you need to know about Cobb County property taxes so you can stay on top of your responsibilities as a homeowner.
What Exactly Are Property Taxes?
Property taxes are charges levied on real estate owners by local government authorities, including counties, municipalities, and school districts. The funds collected are used to support key community services such as law enforcement, fire protection, public education, and road maintenance. In Cobb County, your property tax bill is made up of contributions to several taxing entities, including the County government, your municipality if applicable, the Cobb County School District, and other special districts that provide local services.
How Much Is Property Tax in Cobb County?
In Georgia, property is valued each year as of January 1 for tax purposes. The Cobb County Board of Tax Assessors determines your property’s fair market value, then most residential property is assessed at 40 percent of that amount. Your total tax is calculated by applying the applicable millage rates to your assessed value after exemptions. Because millage rates vary by city and school system, your exact amount depends on your specific location and any exemptions you receive. A simple estimate, Assessed Value equals 40 percent of fair market value, then Tax equals Assessed Value minus Exemptions, multiplied by the Millage Rate divided by 1,000.
When Are Property Taxes Due in Cobb County?
Property taxes in Cobb County are billed annually and are typically mailed by August 15. Full payment is due on or before October 15. Payments must be received or United States Postal Service postmarked by the due date to be considered on time. If October 15 falls on a weekend or holiday, the county will announce any adjusted processing details, so be sure to follow the due date listed on your bill.
When Will You Receive Your Property Tax Bill?
Cobb County typically mails property tax bills by mid August. If your bill does not arrive, you are still responsible for ensuring timely payment. You can look up your property tax information, confirm your balance, or make a payment through the Cobb County Tax Commissioner’s Office. If you need assistance, you can also contact their property tax division by phone.
What Happens If You Miss the Cobb County Property Tax Due Date?
If your taxes remain unpaid after October 15, they become delinquent the next day and begin accruing interest each month. Under Georgia law, interest accrues at an annual rate equal to the Federal Reserve bank prime loan rate plus three percent, set each calendar year and applied monthly. In addition to interest, Georgia law adds a five percent penalty on any unpaid principal at 120 days past due, another five percent every additional 120 days, up to a maximum penalty of 20 percent. Continued nonpayment can result in a tax lien and, if unresolved, a levy and tax sale of the property.

Property Tax Reassessments in Cobb County

If you disagree with your assessed value, you have 45 days from the notice date to file an appeal. Appeals may go to the Board of Equalization, a Hearing Officer, or non binding arbitration, and your notice will explain the options.
