Homestead Exemptions Basics

As a Cobb County resident, homestead exemptions are a great way to reduce the amount of property taxes you pay for your home. But what exactly are homestead exemptions? Homestead exemptions are deducted from the assessed value of the qualifying property (40% of the fair market value). Exemptions only apply to homestead property you own and occupy as your legal residence.

You can have a homestead exemption on only one property. If you are married, by law you can only have one homestead exemption between you and your spouse.

Note: The online application is down for maintenance nightly between 11:50 pm and 5:45 am.


April 1 Deadline

The deadline to apply for a homestead exemption is April 1 to receive the exemption for that tax year.
Applications must be received or USPS postmarked by Tuesday, April 1, 2025, to be accepted for the 2025 tax year.

How to Apply for Homestead Exemptions

Note: The online application is down for maintenance nightly between 12:00 midnight and 5:30am.

Before you apply for homestead exemptions, be sure you meet the following criteria: You own, reside and claim the property as your primary legal residence on January 1.

Applying for homestead exemptions can be done in just a few simple steps.

  1. Confirm all applicants’ names appear on the deed to the property.
  2. Complete the online application. Be sure to apply for only the exemption type for which you are eligible.
  3. Provide a qualifying document to show proof of residency.

Once your application is submitted, we will review and determine if you qualify and inform you if additional documentation is required. It is important that you apply by April 1 in order to review exemption for the current year. Failure to properly and timely file the application constitutes a waiver of the exemption for that year.

Printed applications are accepted via mail or dropped off in-person at one of the property locations. Applications sent by mail must be USPS postmarked by April 1 of the year of filing. We do not accept metered or kiosk postmarks as proof of timely mailing.

City Exemptions

Residents of a city must apply for the city exemptions directly with the city tax office. Questions about exemptions affecting city taxes should be directed to the appropriate city.

Qualifying for Homestead Exemptions
In order to qualify for homestead exemptions, you must provide proof of the following:

  • A copy of your Georgia driver’s license showing you are a permanent and legal resident of both Cobb County and the state of Georgia. The driver’s license must also reflect the property address for which you are claiming the homestead exemption.
  • A copy of your current registration or tax receipt for all vehicles you own showing that you paid motor vehicle taxes in Cobb County. This proof is in accordance with Georgia law (O.C.G.A. § 48-5-444) which states, "Each motor vehicle owned by a resident of this state shall be returned in the county where the owner claims homestead exemption."

Under Georgia law, exemption applications must receive final approval by the Board of Assessors. If denied, you shall have the right of appeal to the county Board of Equalization as provided in O.C.G.A. § 48-5-311.

Once approved, the homestead exemption is automatically renewed each year as long as you continually occupy the home under the same ownership. The only time you must reapply for an exemption is if there is a change in ownership, residence or you wish to qualify for a higher exemption.

Not Eligible

You are not eligible to apply for a homestead exemption if you or your spouse already claim a homestead exemption in another county or state. If you are claiming elsewhere, you must first notify the appropriate authority and provide a letter from that county or state reflecting exemptions have been removed. Property owners found to be claiming homestead exemption on more than one property will be subject to penalties and interest on any taxes saved.

You cannot apply for a homestead exemption on a rental property. Any person who makes any false statement or false representation of a material fact in support of a claim for exemption, or knowingly assists another in the preparation of any false or fraudulent claim, or enters into any collusion with another by the execution of a fictitious deed, deed of trust, mortgage or otherwise, shall be guilty of a misdemeanor. In addition, such property shall be taxed in an amount double the tax otherwise to be paid. (O.C.G.A. 48-5-51).
