Senior Exemption for Individuals 65+
From the Gwinnett County Tax Commissioner website:

If you are 65 years old as of Jan. 1, 2020, and your 2019 GA return line 15 is less than $97,264, you are likely eligible for the Senior School Tax Exemption (L5A).
Contact Gwinnett County Tax Commissioner’s office at tax@gwinnettcounty.com or
