Georgia Property Tax Appeals: What Homeowners Should Know
For many homeowners across the Atlanta metropolitan area, the property tax notice that arrives in the mail each year can come with an unpleasant surprise. If your assessed value increased, your tax bill may rise with it.
Property taxes have recently drawn renewed public attention in Georgia. This week, the Georgia House of Representatives rejected House Resolution 1114, a proposal that would have gradually reduced the portion of a homeowner’s primary residence subject to property tax. Under Georgia’s current system, 40% of a home’s assessed value is taxable. The proposal would have reduced that figure to 10% over the next decade.
To replace the lost revenue, cities and counties would have needed to adopt new sales taxes or other assessments if they wished to maintain existing public services. The measure ultimately failed by a vote of 99–73.
While opinions about the proposal varied, the result means that Georgia’s current property tax system remains in place, and local governments will continue to rely on property taxes to fund schools, infrastructure, and other public services.
For homeowners, that reality raises an important question:
What happens if the county’s value for your property seems too high?
Georgia law gives property owners the right to challenge their assessment through a formal appeal process. While the system has rules and deadlines, it is designed to allow homeowners to present evidence and have their property value reviewed.
If you’re considering an appeal, it helps to understand how the process works.
Why Property Assessments Sometimes Feel Too High
Each year, county tax assessors estimate the fair market value of every property in their jurisdiction. In Georgia, assessments are intended to reflect what a property would sell for as of January 1 of the tax year.
Because counties must value thousands of properties at once, they rely on mass appraisal models. These models analyze recent sales, neighborhood trends, and property characteristics to estimate values across an entire market.
In many cases those estimates are reasonable. But sometimes they miss important details.
A county’s estimate may not fully account for:
Deferred maintenance or property condition issues
Unique characteristics of the home or site
Differences between comparable sales and your property
Rapidly changing market conditions
When that happens, the assessed value may not reflect what your property would actually sell for in the open market.
Georgia law recognizes this possibility and provides a way for homeowners to challenge the assessment.
The Most Important Rule: The 45-Day Deadline
When counties send the annual Notice of Assessment, the clock begins running.
Under O.C.G.A. § 48-5-306, homeowners generally have 45 days from the date printed on the notice to file an appeal.
This deadline is extremely important. If an appeal is not filed within that window, the assessed value typically becomes final for that tax year.
For Metro Atlanta homeowners who believe the value may be inaccurate, reviewing the notice promptly and planning a decision well before the deadline arrives is often the safest approach.
How the Property Tax Appeal Process Works
Although each county may have slightly different procedures, the general process across Georgia follows the same structure.
1. The County Sends a Notice of Assessment
This document shows the county’s opinion of your property’s fair market value for the year. It is not the tax bill, but it determines how the tax bill will eventually be calculated.
2. The Homeowner Files an Appeal
The appeal is typically filed with the county Board of Tax Assessors, often using the PT-311A appeal form.
Most appeals focus on one of three issues:
Value – whether the property is overvalued
Uniformity – whether similar properties are assessed differently
Taxability – whether the property should be taxed at all
Many homeowners appeal simply because they believe the county’s estimated value exceeds what their home would likely sell for in the current market.
3. The County Reviews the Appeal
After the appeal is filed, the county may review the assessment and sometimes offer an adjustment.
If the issue is not resolved at this stage, the appeal may proceed to a hearing.
4. A Hearing May Be Scheduled
Most residential appeals in Georgia are heard by a Board of Equalization (BOE). This panel is typically made up of local citizens who review evidence and determine the appropriate value.
At the hearing, both the county and the homeowner may present information about the property and the market.
The standard used is generally “preponderance of the evidence,” meaning the board decides which value appears more supported by the available facts.
What Evidence Helps in a Property Tax Appeal
Successful appeals usually rely on market-based evidence rather than opinions alone.
Examples include:
Comparable sales (“comps”) - Recent sales of similar homes in the same area can help demonstrate the likely market value of a property.
Property condition issues - Photographs or contractor estimates may show repairs or deferred maintenance that affect value.
Market trends - Evidence showing changes in neighborhood pricing can sometimes support a different value conclusion.
Uniformity comparisons - In some situations, similar homes may be assessed at materially lower values.
Georgia law also allows homeowners to request certain information from the county about how their property was assessed. Under O.C.G.A. § 48-5-306(d), taxpayers may request records related to the appraisal methodology and comparable properties used by the assessor’s office.
A Little-Known Rule That Can Matter: The Two-Year Appeal Lock
One of the most important features of Georgia property tax law is often called the “appeal lock.”
Under O.C.G.A. § 48-5-299(c), if a property’s value is established through an appeal decision or a written agreement with the county, the county generally cannot increase that value for the next two tax years, unless certain conditions change.
For homeowners, this rule can have meaningful financial implications.
If an appeal reduces the value of a property, the tax savings may apply not only to the current year, but also to the following two years.
For example, if an appeal reduces a property’s value by $50,000, the tax savings associated with that reduction may continue for up to three tax years depending on local tax rates.
Because of this rule, some homeowners choose to review their assessments carefully when values rise significantly.
Paying Property Taxes During an Appeal
Filing an appeal does not usually stop the tax process.
In many counties, if the appeal is still pending when tax bills are issued, homeowners may receive a temporary or partial bill. Paying the required amount by the due date helps avoid penalties while the appeal continues.
If the final appeal decision reduces the value, the tax bill is recalculated and any overpayment may be refunded.
Do Homeowners Handle Appeals Themselves?
Many homeowners do.
Georgia’s system allows property owners to represent themselves if they wish. Taxpayers may also authorize representatives, including non-lawyers, to assist with the appeal process.
Some homeowners prefer to gather their own sales data and present their case. Others choose to work with professionals who regularly analyze property values.
There isn’t a single right approach. The decision often depends on the complexity of the property and how comfortable someone feels navigating the process.
Sometimes the conversation begins very simply — the way many good decisions do.
Imagine sitting across the kitchen table, looking at your assessment notice, and asking a straightforward question:
Does this number really reflect what my home would sell for?
That question is often the starting point for many property tax appeals.
A Final Thought for Homeowners
For many Metro Atlanta homeowners, property taxes represent one of the largest ongoing costs of homeownership. When assessments increase unexpectedly, it can understandably create stress or uncertainty.
Georgia law provides a process for homeowners to question their property value and present evidence if they believe the assessment does not reflect the market.
Understanding the 45-day deadline, the type of evidence involved, and the potential multi-year impact of a successful appeal can help homeowners make informed decisions about whether to move forward.
