Gwinnett County, Georgia, sets its senior school tax exemption by a simple formula: $99,648 plus $25,000. For 2026 that comes to $124,648, the most a household can report in Georgia taxable income and still have 100 percent of its school board taxes removed. The exemption, known as L5A, is open to homeowners who are 65 on Jan. 1 of the year they apply.
The figure belongs to the household, not to one spouse. The county counts the applicant and spouse together, and it reads the prior year’s returns to judge a current-year request. The limit has crept up over time: a county release in 2022 put the same cutoff at $105,280.
That raises the question many Gwinnett retirees now face: is the household’s income under the line, and how does it file? The Gwinnett County Tax Commissioner says the school exemption covers the home and up to one acre, and a homeowner who looks too high on paper is still told to apply anyway. The existing homestead exemption stays in place, and the owner can come back later if income drops.

Which income counts toward $124,648?
The test is Georgia taxable income, which is not the same as Social Security checks or gross pay. Georgia lets retirees leave part of their Social Security and retirement income out of the calculation, so a couple with a healthy pension can land well under the line on the state return.
To prove it, the Tax Commissioner asks for pages 1 and 2 of the prior year’s federal Form 1040 and pages 1 through 3 of the Georgia Form 500. Spouses who file separately send both returns. Seniors who are not required to file can offer Social Security, pension and bank statements instead.
Why the school board bill is the one that disappears
L5A removes taxes levied by the Gwinnett County Board of Education. County, city and state levies are untouched. In many Gwinnett households the school levy is the largest single piece of the bill, which is why the Tax Commissioner treats this code as the main prize for older owners.
It is not the only senior code. S3, for homeowners 62 and older, gives a partial school tax exemption but only when Georgia taxable income is $10,000 or less. L3A, a $20,000 county exemption at 65 with the same $10,000 ceiling, is described as most useful to residents of the city of Buford who live outside the Gwinnett County school district.
Does a Gwinnett senior have to reapply every year?
Not under the county’s current guidance. The Tax Commissioner’s homestead exemption page says an approved exemption “automatically renews unless circumstances change and you become ineligible.” A new application is generally needed only after a change in ownership, name or deed, or to qualify for a different exemption. Refinancing does not matter.
The filing date has also shifted in the county’s own wording. A January 2022 release told homeowners to apply online by April 1. The homestead page now says applications are taken year-round, and that a request counts for the current year when it arrives by the appeal deadline printed on the spring Notice of Assessment. A later filing starts with the following year.
Who has to be on the deed, and who has to live there
The age-eligible person must be listed on the deed as an owner. When a home has several owners, only one needs to meet the age test. The home must be the primary residence on Jan. 1 of the application year, and a homeowner can hold a homestead exemption on only one property. Married spouses share one exemption.
The exemption ends the following tax year if the eligible person comes off the deed or stops qualifying, and the Tax Commissioner requires owners to report that change. The 2026 property tax bills are due Nov. 15, so a household that applies now is working on next year’s bill. The county’s online homestead application serves every exemption code, and the Customer Contact Center takes questions at 770-822-8800.
Is a Gwinnett household close to the $124,648 line?
A couple near the ceiling is the one that gains most from running the Georgia taxable income figure before the appeal deadline.
A Gwinnett household that misjudges its Georgia taxable income, or files after the appeal deadline, can wait another year for a school tax bill to drop. An owner who comes off the deed or loses eligibility also has to report it to avoid trouble later.
The Senior Property Tax & Home-Cost Relief Kit sets out the 5 kinds of property-tax relief in plain language, so a Gwinnett homeowner can see where L5A, S3 and L3A fit. It also comes with an application log and renewal calendar, which keeps each filing date and each proof of income in one place.
