⚡ Quick Answer
To appeal your property taxes in Georgia, file a written appeal with your county Board of Assessors within 45 days of receiving your assessment notice. You can appeal on the grounds of value, uniformity, or taxability. Most successful appeals result in a 5–15% reduction — and you don’t need a lawyer to do it.
Quick Answer
How do you appeal property taxes in Georgia?
File Form PT-311A with your county Board of Assessors within 45 days of your Annual Notice of Assessment. State your grounds (value, uniformity, or taxability) and your asserted fair market value. Use comparable sales from the prior calendar year only — the same year the county used to set your value. If the Board of Assessors does not resolve the appeal, it is automatically certified to the Board of Equalization for a free independent hearing. No attorney required. No risk of your value being raised for simply filing. The filing fee is zero.
Every spring across Walton, Gwinnett, Barrow, DeKalb, Oconee, Newton, and Jackson counties, Board of Assessors offices mail Annual Notices of Assessment to every property owner. Every spring, most property owners do nothing. That is a mistake. Appealing your Georgia property taxes costs nothing but a few hours of preparation — and the upside can be hundreds or thousands of dollars off your annual bill with no risk of your value going up simply because you asked.
As a REALTOR® serving the Atlanta-to-Athens corridor since long before the current market run-up, I’ve watched homeowners in Loganville, Monroe, Covington, Winder, Watkinsville, and Jefferson absorb assessment increases that were neither justified by the market nor inevitable. I’ve also been through the appeal process myself — including learning the hard way that using the wrong sales year gets your entire comp package discarded on the spot. This guide gives you everything you need to fight back correctly, the first time.

When Are Assessment Notices Sent in Georgia?
Under O.C.G.A. § 48-5-306, all Georgia counties are required to mail an Annual Notice of Assessment to every taxable real property owner each year. Most metro Atlanta counties and their East Georgia neighbors — including Walton, Gwinnett, Barrow, DeKalb, Oconee, Newton, and Jackson — send notices between late April and June, though the exact mailing date varies county by county.
Your notice includes the county’s estimated fair market value as of January 1 of the tax year. Because Georgia assesses at 40% of fair market value (O.C.G.A. § 48-5-7), the number you will challenge in an appeal is the fair market value line. A successful reduction automatically reduces the 40% assessed figure — and your annual bill.
If your value did not change year-over-year, your county may not mail a notice. No notice does not mean no right to appeal — but confirm the deadline with your county assessor’s office directly, since the 45-day clock can begin from the date a notice should have been sent.
The 45-Day Deadline You Cannot Miss
The deadline to appeal property taxes in Georgia is 45 days from the date printed on your Annual Notice of Assessment, per O.C.G.A. § 48-5-311. This window is firm. Miss it and you forfeit your right to appeal for the current year, regardless of how significant the overvaluation is.
This is not a statewide uniform date like Texas’s May 15 deadline. In Georgia the clock starts from the date on your specific notice — and that date varies by county. Your neighbor in Newton County may have a different cutoff than yours in Walton County.
When your notice arrives, write the 45-day deadline on your calendar immediately. Set a reminder for Day 35 to give yourself buffer. This single habit is the most important step in the entire process.
Step 1: Review Your Notice for Errors
Before you file anything, spend ten minutes checking whether the county’s data on your property is accurate. Georgia counties use mass appraisal — statistical models applied to thousands of properties at once — and errors are common, particularly in fast-growing corridors like Grayson, Dacula, and Bethlehem where new construction sales are routinely used to value older, established neighborhoods.
Check your notice for:
- Incorrect square footage, bedroom count, or bathroom count
- Listed improvements that don’t exist (pools, garages, finished basements, accessory structures)
- Wrong property classification (residential vs. commercial)
- A large year-over-year value jump with no corresponding change to your property or immediate market
- The estimated rollback rate line now required by HB 581 — this shows what millage rate would hold your bill flat, revealing the real financial impact
If any of these apply, you have a data-error argument to add alongside your market value argument. Both are valid grounds under Georgia law.
Step 2: Verify Your Exemptions First — Including HB 581
Exemptions and appeals are separate tools that work best together. Verify yours are applied before you focus exclusively on the value protest.
Standard Homestead Exemption
Georgia’s statewide base exemption is $2,000 off your assessed value for school taxes (O.C.G.A. § 48-5-44). It is the foundation on top of which local exemptions stack. Apply through your county tax assessor’s office by April 1 of the tax year if you own and occupy the home as your primary residence.
Georgia voters approved Constitutional Amendment 1 in November 2024, enacting HB 581 effective January 1, 2025. This created a statewide floating homestead exemption that limits annual increases in your home’s taxable assessed value to no more than the state’s inflation rate (based on CPI), using your 2024 assessed value as the base year.
Example: If your home’s base assessed value is $200,000 and fair market value jumps to $240,000 the following year, the floating exemption covers the $40,000 difference (adjusted for CPI), so you are taxed on roughly $200,000 — not $240,000.
Critical caveat: Individual counties, cities, and school districts were permitted to opt out by March 1, 2025. Many did. Check directly with your county assessor’s office — Walton, Gwinnett, Barrow, DeKalb, Oconee, Newton, and Jackson each made separate decisions. HB 92 (2025 session) also made revisions to HB 581 provisions. For the most current status, see dor.georgia.gov/hb-581-resources.
Additional Local Exemptions Worth Checking
- Senior school tax exemptions: Starting at age 62 in many counties. Some offer a full school tax exemption at 65+ subject to income limits. Gwinnett, Walton, Oconee, and Newton each have different thresholds and amounts — check your specific county.
- Local floating homestead exemptions: Some counties had their own floating exemptions before HB 581. Georgia law requires you receive whichever is more beneficial — confirm with your county which applies.
- Veterans exemptions: Disabled veterans may qualify for significant additional relief. Confirm eligibility directly with your county assessor.
Under HB 92, you may also apply for homestead exemptions during the 45-day appeal window even if you missed the original April 1 deadline — but applications during this window typically must be submitted in person at the assessor’s office.
The most powerful strategy: reduce the fair market value through appeal, then let exemptions reduce the taxable value further from that lower baseline. If HB 581 is in effect in your jurisdiction, a successful appeal also lowers your floating cap baseline — compounding savings into future years.
Step 3: Choose Your Appeal Grounds
Georgia law recognizes three bases for appealing a property tax assessment. When you file Form PT-311A, you must specify your grounds. Choose carefully — each affects what evidence carries weight and, for some options, what further appeal rights you retain.
- Value: The county’s fair market value estimate is too high. The most common ground — supported by comparable sales evidence.
- Uniformity: Your property is assessed at a higher percentage of market value than similar properties in the county. You may have a uniformity argument even if the absolute value is defensible on its own.
- Taxability: The property should not be taxable, or should be taxed at a different classification. Less common for residential, but critical if your agricultural exemption was denied or your property was reclassified.
Assert both value and uniformity on your appeal form. Preserving both arguments gives you the widest grounds at the Board of Equalization hearing and on any further appeal.
Step 4: File Your Appeal — And Why the Number You Write Matters
Most Georgia counties now offer online filing through their assessor portal — the fastest method and one that creates a timestamped record. Filing options:
- Online portal: Check your county assessor’s website. You will need your parcel number from the notice.
- Mail: Form PT-311A to the address on your Annual Notice of Assessment.
- In person: Counter or drop box at the county assessor’s office during business hours.
Your appeal must identify the property, state your grounds, and include your asserted fair market value — the number you believe the property is actually worth. No attorney required. A written letter meeting those basic criteria is legally sufficient under Georgia law, though the official Form PT-311A simplifies the process.
The fair market value you write on Form PT-311A is the lowest number the board can award you — even if your evidence clearly supports going lower. If you enter a number higher than your true target value, the board cannot reduce your assessment beyond what you filed, even when they agree your evidence justifies a lower figure.
Do not treat this line as a negotiating opener or a rough estimate. Pull your comps first (see Step 5), determine the specific value they support, and write that exact number. A preventable error on this single line can cost you thousands — even after winning the argument in the room.
Once you file, Georgia allows you to pay taxes at a temporary value while the appeal is pending. The default (Option 1) is the lesser of your prior year’s final value or 85% of the current year value. Option 2 allows payment at 100% of the current value. Any difference is refunded or re-billed once the appeal resolves. If you do not specify an option, Option 1 is applied automatically.
Step 5: Gather Your Evidence — The Calendar Year Rule
Evidence is the engine of a successful Georgia property tax appeal. The Board of Assessors and Board of Equalization make decisions based on evidence — not frustration, not the millage rate, and not what you paid for the property.
Comparable Sales — The Rule Most People Get Wrong
Your comps must be arm’s-length sales of properties similar to yours that sold for less than your assessed fair market value. Here is the rule that catches most first-time appellants off guard: comps must be from the prior calendar year only. For a 2026 assessment, that means only sales that closed during 2025. A 2026 sale will not be accepted — and neither will a 2024 sale.
This is not arbitrary. The entire county-wide assessment is built exclusively on sales from that same calendar year. Allowing any individual homeowner to use sales from a different period — particularly more recent sales that may reflect a softening market — would be inequitable to every other taxpayer whose value was set by the same data set. The board enforces this rule uniformly. Walk in with 2026 comps and they will be discarded entirely, no matter how compelling the numbers look.
Go directly to your county assessor’s public records portal and pull sales from the correct calendar year. This is the same data the county used to set your value — which means it is also the data you can use to challenge it. Filter by the prior calendar year, your property type, and your general area. Sort by price per square foot or sale price and identify the sales that support your target value.
Georgia assessors are also required to document the comparable sales that supported their valuation — you have the right to request their comp package. Reviewing their selections before the hearing often reveals exactly where to attack their methodology.
Hearing strategy: Let the county assessor present their evidence first. Once they finish, present yours. Walking in with clean, calendar-year-correct comps pulled directly from the county’s own data is a position of strength. A well-prepared homeowner who comes in with real evidence — specific sales, specific prices, specific addresses — will often be the only person in that room doing so. County appraisers, when faced with solid data they cannot dispute, will say so directly.
Independent Appraisal or CMA
A written market analysis from a licensed Georgia real estate agent or a certified appraisal report provides third-party credibility. For the arbitration path, a certified appraisal is required — a broker opinion alone will not suffice at that level. Note that any CMA or appraisal used should also draw from prior-calendar-year sales to be consistent with the board’s methodology. If you are a homeowner in the Atlanta-to-Athens corridor and want a market analysis to support an appeal, reach out to our team.
Supporting Evidence
- Photographs of condition: Deferred maintenance, foundation issues, water intrusion, outdated systems, or documented flood zone exposure all support a lower value claim.
- Repair estimates: Contractor bids for needed work are admissible evidence of reduced value.
- Uniformity evidence: If comparable properties carry lower assessed values relative to their market values, pull that data from your county’s public records and present the disparity directly.
Remember: a $30,000 reduction in fair market value translates to a $12,000 reduction in assessed value (at Georgia’s 40% ratio) and meaningful tax savings at any millage rate.
Step 6: Board of Assessors Informal Review
After you file, the county Board of Assessors (BOA) reviews your appeal and has up to 180 days to notify you of its decision, though most counties act sooner. During this phase:
- The BOA may reduce your value, resolving the appeal
- The BOA may leave your value unchanged and certify the appeal to the Board of Equalization
- You may be offered a settlement conference — an informal negotiation with a staff appraiser
If you reach a written settlement with the BOA, that value is generally final for the tax year and cannot be appealed further through a lawsuit. Weigh settlement offers carefully if you believe your property is significantly overvalued — accepting a partial reduction closes the door on a potentially larger win at the BOE. If the BOA makes no changes or you decline the settlement, your appeal is automatically certified to the Board of Equalization. No additional action is required from you.
Step 7: Board of Equalization Hearing
The Board of Equalization (BOE) is Georgia’s first independent appeals tribunal — a three-member panel of county property owners (not county employees) appointed to hear assessment disputes. There is no charge to bring your appeal to the BOE.
What to expect:
- A panel of three independent citizen members
- The county assessor presents their evidence first — let them go, then present yours
- Hearings typically run 20–45 minutes
- Bring at least three printed copies of your evidence package
- The panel issues a written decision — it is not negotiated on the spot
Keep your presentation evidence-focused. The BOE’s role is to determine correct fair market value based on what you and the county present. Do not argue your millage rate, your school taxes, or what you can afford. A successful BOE outcome comes down to better comparable evidence — period. The bar is lower than most people expect: the majority of homeowners who show up with no prepared evidence at all.
If dissatisfied with the BOE’s decision, you have 30 days from the date of the written decision to file a further appeal.
Step 8: After the BOE — Further Appeal Options
If the BOE rules against you and the value difference is material, three paths remain:
Hearing Officer
Available for non-homestead real property valued at $500,000 or more (O.C.G.A. § 48-5-311). Hearing officers are state-certified real property appraisers approved by the Georgia Real Estate Commission and the Georgia Real Estate Appraisers Board. Generally faster and more technically focused than Superior Court — often the best next step for high-value commercial or investment property.
Nonbinding Arbitration
You may request arbitration instead of the BOE hearing by specifying it within your 45-day appeal window. Arbitration requires a certified appraisal within 45 days of filing. The arbitrator’s decision is nonbinding — either party can reject it and proceed to Superior Court — but it creates a useful settlement data point.
Superior Court
File within 30 days of the BOE’s written decision. You are required to pay the undisputed portion of taxes before the delinquency date. Superior Court is the most expensive and time-consuming path; consult a Georgia property tax attorney before proceeding. For most residential owners, the math only works on high-value properties or where the BOE made a significant error.
Part 2: Appealing Property Taxes on Land and Acreage in East Georgia
Rural and agricultural landowners in counties like Oconee, Jackson, Barrow, Newton, and Walton face the same 45-day deadline and basic filing procedure. The evidence strategy and the most common appraisal errors, however, are quite different from residential appeals.
The Mass Appraisal Problem for Rural Land
Georgia county assessors rely heavily on mass appraisal models built primarily on residential sales data. When applied to rural acreage, these models produce unreliable results for several reasons:
- Thin comparable sales data. Many East Georgia counties have limited rural land transactions, forcing extrapolation from a small and potentially unrepresentative dataset.
- Blanket per-acre valuations that ignore road frontage, water features, timber quality, flood plain percentage, soil type, and distance from utilities — all of which directly affect buyer behavior.
- Development pressure contaminating agricultural values. In fast-growing fringe counties — Oconee, Jackson, Barrow — assessors sometimes use transitional property sales (land priced for subdivision potential) to value working agricultural tracts with no realistic near-term development prospects. These are not equivalent comparables. Challenging that selection directly is often your strongest argument. And the same calendar year rule applies — all land comps must be from the prior calendar year.
Conservation Use Valuation (CUVA) and How It Affects Your Appeal Decision
Under O.C.G.A. § 48-5-7.4, Georgia’s Conservation Use Valuation Assessment (CUVA) creates a separate, lower taxable value based on current land use rather than market potential. This distinction matters when deciding whether to appeal:
If your land carries an active CUVA covenant, appealing the fair market value still makes sense for two reasons:
- Conservation Use Breach penalties. If you ever sell, change use, or let the covenant lapse, the state can assess a breach penalty equal to three times the tax savings realized during the covenant period, plus interest. A lower certified fair market value directly reduces that liability.
- Future year baseline. HB 581 now requires chief appraisers to revalue all properties at least once every three years. The baseline you lock in today is more consequential than ever.
Georgia also offers Forest Land Protection Act (FLPA) conservation use valuation for qualified timberland under O.C.G.A. § 48-5-7.7. If your CUVA application was denied or is under review, resolving the classification dispute takes priority over a market value appeal — the tax difference from a lost CUVA on productive farmland or timberland typically dwarfs any market value reduction you might achieve through the appeal process.
Evidence Strategy for Land Appeals
- Land-to-land comps only, prior calendar year. Do not allow the county to use improved sales to value raw acreage without substantial downward adjustment — and ensure every comp you bring is from the correct year.
- Match meaningful characteristics: acreage, road frontage, water access, terrain, timber quality, soil type, flood plain percentage, proximity to urban centers.
- Document what did not change. If no road was built, no utility line extended, no zoning changed, and no nearby development occurred — that absence of value triggers is relevant evidence when the county claims significant appreciation.
- A land-specific market analysis from a Georgia land professional actively selling in that county carries real credibility with the BOE — more so than a standard residential CMA.

Frequently Asked Questions
Can my property value go up if I file an appeal?
No — at least not as a direct result of filing. The Georgia appeal process does not give the county the ability to raise your value as a punitive response. If a site inspection reveals previously unrecorded improvements, the county may update its record independently, but filing a well-supported appeal carries no meaningful downside risk for most residential owners.
What year do my comparable sales need to be from?
From the prior calendar year only. For a 2026 assessment, only 2025 sales are accepted. A 2026 sale will be discarded, and so will a 2024 sale. The entire county assessment is built on that same year’s sales data, so all homeowners must use the same pool — no exceptions. Pull your comps directly from the county assessor’s public portal using the correct year filter before you file or walk into any hearing.
Does the value I write on Form PT-311A matter?
Critically. The number you write is a hard ceiling — the board cannot reduce your assessment below it, even if your evidence supports a lower figure. Pull your comps first, determine the specific value they justify, and write that exact number. Do not estimate. Do not round up thinking you’ll negotiate down. Write the number you’ve actually proven with data.
Do I need a lawyer to appeal property taxes in Georgia?
No. Georgia property owners regularly represent themselves at the Board of Assessors and Board of Equalization level. For high-value properties, complex land situations, or Superior Court proceedings, a Georgia property tax attorney or professional consultant may be worth the cost. For most residential owners, the evidence preparation is a manageable DIY project.
What if I missed the 45-day deadline?
Your options narrow considerably. Georgia has no built-in “good cause” exception to the 45-day window after a Notice of Assessment. However, under O.C.G.A. § 48-5-311(g), if you never received a required notice, you may have a separate avenue to appeal tied to the tax delinquency date. Consult a Georgia tax attorney quickly if you believe you had a right to notice and did not receive one.
What is the 40% assessment ratio and can I dispute it?
Georgia law (O.C.G.A. § 48-5-7) requires all property to be assessed at 40% of fair market value. This ratio is not disputable — it applies uniformly statewide. Your appeal targets the fair market value figure, not the ratio itself. If you believe the ratio is being applied inconsistently across your county, that is a uniformity argument — a valid separate ground of appeal.
What is the HB 581 floating homestead exemption?
Effective January 1, 2025, HB 581 created a statewide floating homestead exemption that limits annual increases in your home’s taxable assessed value to no more than Georgia’s inflation rate (based on CPI), using the 2024 assessed value as the base year. Counties, cities, and school districts could opt out by March 1, 2025 — many did. Check with your specific county assessor’s office. See dor.georgia.gov/hb-581-resources for official guidance.
How does a successful appeal interact with my HB 581 floating exemption?
If you have the floating homestead exemption and successfully reduce your fair market value through an appeal, the lower value becomes your new base year value for the floating cap — potentially compounding your savings in future years. This makes a successful appeal especially valuable for homeowners in jurisdictions where HB 581 is in effect.
Does a lower tax-assessed value affect what my home sells for?
No. The county’s assessed fair market value and a buyer’s independent market valuation are separate things. A lower tax-assessed value does not reduce what your property is actually worth or what it will sell for. Buyers use their own analysis, comparable sales, and appraisals — not your tax notice.
What happens if I miss my BOE hearing?
Your appeal may be dismissed. Missing the Board of Equalization hearing is one of the most avoidable and costly mistakes in the Georgia appeal process. If you have a documented emergency, contact the BOE office immediately — some counties may reschedule for documented good cause, but it is not guaranteed.
