Georgia has five types of property tax appeal help available. This guide compares going alone, flat-fee DIY packets, contingency firms, tax consultants, and attorneys on cost, effort, and ROI so you can choose the right option before your appeal deadline.
Eight out of ten Georgia homeowners have never appealed their property taxes. That number is staggering when you consider that 49% of homes in Gwinnett County alone were overvalued in 2025. and Gwinnett is not an outlier. Across metro Atlanta, county assessors are systematically overestimating property values, and homeowners are paying the difference in higher tax bills every single year.
If you are looking for the best property tax appeal service in Georgia, the answer depends on what kind of help you actually need. There are five distinct categories of appeal assistance, ranging from completely free to thousands of dollars. Each one fits a different homeowner profile. This article breaks down all five so you can make the right call before your appeal deadline.
Georgia law requires all property to be assessed at 40% of fair market value. Your county multiplies that assessed value by the local millage rate to calculate your tax bill. If the county overestimates your home's fair market value, you overpay. and the only way to fix it is to appeal.
The process starts when you receive your Annual Assessment Notice, usually between April and June. Georgia law sets the appeal deadline at 45 days from the date on that notice to file a PT-311A appeal form with your county Board of Assessors. The county reviews your appeal, and if they do not agree to reduce your value, it goes to a Board of Equalization hearing where a three-person panel reviews the evidence from both sides. There is no filing fee. The date printed on your notice controls. Confirm with your county before you file.
One of the most powerful incentives to appeal is Georgia's three-year value freeze. Under O.C.G.A. 48-5-299(c), if an appeal reduces your value, the assessors cannot raise it for the next two years, subject to the statutory exceptions. HB 581, which took effect in 2025, changed the rules: you now need an actual reduction for the freeze to apply. Simply filing and showing up is no longer enough.
Not all appeal services work the same way. The five categories below cover every option available to Georgia homeowners, from doing everything yourself to hiring a property tax attorney.
This is the zero-cost path. You research comparable sales, fill out the PT-311A form, file with your county, and attend the Board of Equalization hearing on your own. Everything from start to finish is on you.
The appeal itself is free. no filing fee, no required appraisal, no mandatory attorney. Georgia's Property Taxpayer's Bill of Rights specifically protects your right to represent yourself at a BOE hearing.
The upside is obvious: it costs nothing. The downside is less obvious but more painful. Unprepared filers have a success rate of roughly 5-10%. Finding quality comparable sales, adjusting for differences in square footage and lot size, and building a coherent argument takes 15-40 hours of research. Many homeowners who go fully alone submit weak evidence. or no evidence at all. and lose appeals they could have won.
This path works best for homeowners with time, research skills, and a small overassessment where the stakes are low enough to experiment.
Flat-fee services sit in the gap between doing everything yourself and hiring someone to handle it for you. For a one-time fee. typically $49-$150. you receive a professional-quality evidence packet that includes comparable sales analysis, a pre-written appeal argument, and county-specific filing instructions. You still file the appeal and attend the hearing yourself.
The ROI math on this category is hard to beat. A flat fee against a potential $1,000+ annual savings. with no percentage of savings owed. means you keep 100% of the reduction. The only limitation is that you still need to do the filing paperwork and may need to attend a BOE hearing, which typically takes 15-20 minutes.
This category works best for motivated homeowners who want strong, professional-quality evidence without spending 15-40 hours doing the research themselves. It is the highest-ROI option for most Georgia homeowners with a clear overassessment.
Full-service appeal companies handle your appeal as your agent: they file your appeal, prepare the evidence, and manage the case. Pricing models vary. Some charge a pure contingency fee. typically 25-35% of first-year tax savings with nothing due upfront. Others charge an upfront engagement fee ($50-$200) plus a contingency percentage. A few charge flat fees regardless of outcome.
AppealAlly's Full-Service Appeal uses a contingency model: 30% of first-year tax savings, charged only if we win, with nothing due upfront, plus a one-time $25 fee if the county grants Georgia's 3-year freeze. Not all companies work this way, so read the fee structure carefully before signing up.
The tradeoff with any contingency service is real, though. On a $1,000 annual savings, a 30% fee takes $300 in year one. If the reduced value holds in years two and three under the 299c freeze, subject to the statutory exceptions, you keep the full savings then, but you have permanently given up nearly a third of year one.
There is another subtlety worth knowing. Some contingency firms file appeals on marginal cases where the odds of a reduction are low. They can afford to do this because losing costs them nothing. but it costs you time and creates a record of appeal activity on your property. Under HB 581, if they achieve no reduction, you get no three-year freeze either.
This path works best for homeowners who want completely hands-off service and do not mind sharing a portion of their savings. It is most cost-effective when potential savings are large. $500/year or more. because the fixed overhead of the contingency percentage is spread across a bigger number.
This category covers two distinct professionals who often work together.
Tax consultants are frequently former county assessors or BOE members who know the system from the inside. They charge either a contingency fee (30-35% of savings) or a flat fee ranging from $300 to $1,000 or more, depending on the property's complexity. They handle the filing and hearing strategy, and their local relationships with county staff can be an advantage.
Independent appraisers provide a certified appraisal. the single strongest piece of evidence you can bring to an appeal. A residential appraisal in Georgia costs $350-$750. The appraiser does not file your appeal or attend the hearing; they produce a formal opinion of value that you or your consultant presents. If you go the arbitration route instead of the BOE, a certified appraisal is required.
The combination of a local tax consultant and a certified appraisal is powerful but expensive. For a $500,000 home, you might spend $500 on the appraisal plus $300-$500 for the consultant. $800-$1,000 before seeing any savings. The evidence quality is typically excellent, but the cost only makes sense when the overassessment is substantial.
This path works best for homeowners with complex properties. unusual construction, large lots, waterfront, income-producing features. or anyone who wants the strongest possible evidence for a high-stakes appeal.
Attorneys charge $200-$500 per hour or a retainer of $1,000-$5,000 or more. They provide full legal representation and can take your case through Superior Court if the BOE rules against you.
For most residential properties, attorney fees exceed the potential savings. A $2,000 retainer on a $400 annual reduction does not make financial sense. But there are situations where legal representation is necessary or even cost-effective.
Georgia's 85% rule is the key. Under O.C.G.A. 48-5-311, if the Superior Court sets your value at 85% or less of what the Board of Equalization determined, the county must pay your reasonable attorney fees. This makes litigation viable for properties where the BOE decision was clearly wrong by a wide margin.
There is also a legal requirement to know about: at the Superior Court level, properties owned by LLCs or corporations must be represented by an attorney. You cannot represent a business entity yourself in court.
This path works best for high-value residential properties (over $750K), commercial properties, cases heading to Superior Court, and any LLC-owned property that needs to appeal beyond the BOE level.
Four variables determine which path makes the most sense for your situation.
Property value. If your home is assessed under $300,000, a flat-fee evidence packet or going alone gives you the best return. Between $300,000 and $750,000, a flat-fee packet remains the highest-ROI choice, though contingency services become more justifiable as potential savings grow. Above $750,000, the stakes are high enough to consider contingency firms, a certified appraisal, or attorney representation.
Comfort level. If you are comfortable with paperwork and can present data in a structured format, a flat-fee evidence packet gives you everything you need at minimal cost. If the thought of filing a form or sitting in a hearing makes you anxious, a contingency firm handles it all.
Time available. Have 1-2 hours? A flat-fee evidence packet comes with everything prepared. you just file and present. No time at all? A contingency firm does the work. Willing to invest 15-40 hours doing your own research? Going fully alone costs nothing.
Potential savings amount. Run the math before choosing. The formula is:
Annual Savings = (Overassessment x 0.40) x Mill Rate / 1,000
If your annual savings would be under $200, a flat-fee evidence packet is your best bet. contingency firms and appraisers will eat most of the savings. If annual savings exceed $500, contingency or professional help may justify the cost. If savings exceed $2,000 per year, attorney representation at Superior Court becomes a real option, especially with the 85% rule in play.
Here is the decision simplified:
Georgia's value freeze under O.C.G.A. 48-5-299(c) can make every service category more valuable than it first appears. When you win a reduction, the county assessors cannot raise the reduced value for the next two years, regardless of what the market does, subject to the statutory exceptions.
If the reduced value holds, subject to the statutory exceptions, a $500 annual saving becomes an estimated $1,500 over three years.
But HB 581 changed the stakes. Before 2025, homeowners could trigger the freeze by simply filing and appearing at the hearing. That loophole is closed. Now, you must actually win a value reduction to activate the freeze. This makes evidence quality the deciding factor in your appeal, regardless of which service type you choose. A weak case that ends with no change starts no hold.
The right property tax appeal service for you comes down to three things: your property's value, your comfort with paperwork, and how much time you are willing to invest. For most Georgia homeowners. especially those in metro Atlanta counties where overassessment rates are highest. a flat-fee evidence packet delivers the strongest return per dollar spent.
Across every service category, not checking can cost you if your home is overvalued. With nearly half of homes overvalued in some Georgia counties and a reduced value that can keep saving you money for up to three years, subject to the statutory exceptions, it is worth confirming that your assessment is not too high.
