atlanta property tax appeal

Young, diverse, and vibrant, the Atlanta area has become one of the most in-demand places to live in the United States over the past decade. Drawing in people, corporations, and investments, the Atlanta area is the crown jewel of the New South. Thanks to numerous tax incentives, the area is welcoming big tech, Hollywood, and a growing range of industries. The downside is that the property values across the area have skyrocketed in the past decade, often making it difficult for working families and seniors to stay in their homes.

The two main ways to fight against the rising values are exemptions and property tax appeals. These two techniques can and should be used in tandem. The appeal season is about to get underway in the Atlanta area, with some counties already in the mix. There is only a limited timeframe to protest, and these windows will soon be opening and closing across the area.

Assessment Notices

Unlike many other states, Georgia does not use a statewide deadline or a specific county cutoff date. Instead, assessment notices are sent out in the late spring or early summer, triggering deadlines upon mailing. Each county’s Board of Tax Assessors (BTA) tries to send assessments out all at once, creating a general uniform timeframe for appeals, though deadlines can still vary by taxpayer. Taxpayers will have 45 days from when the notice was issued to file their appeals. The issuance date will appear on the notice itself, making it an important document to keep track of.

What to Consider When Thinking of Appealing

The notice contains several key pieces of information that you will need to verify. This starts with basic information, such as size, location, ownership, and exemptions. All of these need to be correct, as any issue can cause extensive increases in taxes, especially missing exemptions. If you were denied an exemption, you can appeal for a second chance to receive it. Clerical errors can still be fixed after the deadline, so if your home is measured incorrectly, you still have a chance to remedy the situation. The same is not true for property values.

Next, the values that are assessed to your property should be checked. The main value is the fair market value (FMV), which is what tax bills are based on. Under Georgia law, only 40% of a residence’s market value can be used for taxes, which results in the assessed value figure. This is the number that is reduced by exemptions. The fair market value should be examined closely, as this is what can be appealed. If you have seen a large spike in market value between 2025 and 2026, then that should be investigated with an appeal. Also, under Georgia law, properties in the same location with the same characteristics should be assessed equally. Check the assessments of your neighbors via your BTA’s website to ensure that you are not being valued unfairly. If either of these circumstances applies, then you should consider an appeal.

2026 Deadlines

In the past few years, values in the metro Atlanta area have been released early, which sped up the appeal process. This does not appear to be the case in 2026, and all of the primary counties seem to be getting their notices on time or a little late. This pushes the deadlines farther back than in recent years, giving taxpayers a little more time to prepare. As is tradition, Gwinnett County kicks off the appeal season.

Gwinnett County Is Up First

Gwinnett County is always the first of the major metro Atlanta counties to see a notice of assessment, with most getting their notices in early or mid-May. All taxpayers should have their notices by this point, and it appears that most homeowners and businesses will see deadlines of around June 29. As always, it is important to check your notice to be sure what date is correct.

DeKalb County Deadlines Set for Around July 13

DeKalb always follows in the footsteps of Gwinnett, and the majority of notices were mailed out around May 29, 2026. This means that an appeal deadline should be set for around July 13. This is the common pattern for DeKalb County, meaning it has not experienced delays like some neighboring counties. If you are in DeKalb County and have not received your notice yet, it is imperative that you check your BTA’s website or contact them directly to verify when you will receive it and when your appeal deadline will be.

Cobb County Notices Set to Mail Out June 5

Notices of assessment traditionally come out next in Cobb County. Currently, these are scheduled for release around June 5, 2026, which is a few weeks later than previous years. This would make the deadline target around July 20, 2026. With some counties experiencing delays, this could be pushed back a bit further. In the past few years, Cobb sent out notices in early or mid-May.

Fulton County Eyes Mid-June to Mail Out Notices

Currently, Fulton is the only major county that does not have a firm release date. As the home of most of Atlanta, this county has the largest economy and population, making it difficult to assess and send out notices on time. Notices may not arrive in one big block, which makes checking the notices vital to see the exact deadline. This delay means that the deadline could be late July and even early August for most residents of Atlanta proper.

Gathering Evidence Should be a Top Priority

Whether your notice has arrived or not, your main focus should be gathering evidence. Depending on what you want to appeal, this will mean different things. If you believe your property has been overvalued, you should photograph the property, documenting any conditions or changes that could affect your market value. Next, you will want to gather sales records dating back three years for your neighborhood, using homes or businesses with the same location, age, and size as your own. If you are looking to show unequal assessment, then you will need to gather several assessments from your general location that demonstrate that you are being assessed more than your peers. Your portfolio of evidence can also be boosted by repair estimates and independent appraisals to document condition, size, and any issues like damage or deferred maintenance.
