How to Apply for a Homestead Exemption
If you own and occupy a home in Lamar County, Georgia, as your primary residence, you may qualify for a homestead exemption that reduces the property’s taxable assessed value.
Basic Eligibility
• You must own the property and occupy it as your primary residence on January 1 of the tax year.
• The standard homestead exemption is available to qualifying homeowners regardless of age or income.
• Additional exemptions may be available for residents age 62 or older, residents age 65 or older, disabled veterans, and certain surviving spouses.
Apply for the Exemption
1. Choose the application that fits your situation: Standard Homestead, age 65 or older, or age 62 school-tax exemption.
2. Complete the application and gather a copy of your driver’s license. For an income-based exemption, also provide your federal Form 1040 or sign an income affidavit. Special exemptions may require additional documents.
3. File the initial homestead application with the Lamar County Tax Assessor’s Office. Applications may be filed during the year, but file by April 1 for the exemption to apply to the current tax year. You must have owned and occupied the home as your primary residence on January 1.
4. Once approved, the exemption normally renews automatically unless ownership changes or you apply for a different exemption.
Deadlines
All homestead exemption applications must be filed by April 1 for the exemption to apply to the current tax year.
