State law requires a Douglas County appeal within 45 days of your notice. How to file, what happens next, and when the tax bill is due.
# Douglas County, GA Property Tax Appeal: Deadline and Steps
To appeal a Douglas County, Georgia property tax assessment, state law requires you to file a written appeal with the county Board of Assessors, through its Appraisal Department, within 45 days of the date your assessment notice was mailed. For 2026, the county's Appraisal page listed June 16, 2026 as the mailing date and July 31, 2026 as the estimated last day to appeal, so the window has closed for notices mailed June 16 unless you already filed. If your notice prints a later last day to appeal, that date governs.
Beyond the appeal steps, the guide covers when the Douglas County tax bill is due and what the county's millage votes actually did to the rate.
Searches for "Douglas County" also return pages from Douglas counties in other states, with different payment dates and hearing rules. Everything below comes from Douglas County, Georgia's own offices (douglascountyga.gov and douglastax.org), the Georgia Department of Revenue and Georgia law.
Confirm with your county before you file.
The last day to file is printed on your notice, and that printed date governs. Georgia law sets it at 45 days after the notice was mailed, and the county's Appraisal page describes the same window as 45 days from the date of the notice; for 2026, both point to the same day.
The county published these 2026 dates:
The county's page also says, in capital letters, that it cannot extend the time to file an appeal. It asks owners to file early and keep a copy in case of system problems.
A mailed appeal counts as filed on its postmark date, and the Georgia Department of Revenue's Douglas County page says it must be postmarked no later than day 45 after the notice was mailed.
The county has said it can't extend the time to file, so the window to appeal your 2026 notice has passed. Your next window opens when next year's notice arrives, estimated sometime between April 15 and July 1 based on the range the county gives for its mailings, with a new 45-day window from that notice's mailing date.
When that notice comes, what to check first on a Georgia assessment notice walks through each line.
Confirm with your county before you file.
Georgia assesses most property at 40% of its fair market value, and your tax is figured on that 40% figure, less any exemptions. Fair market value is the Board of Assessors' estimate of what your home would sell for, and your 2026 annual notice lists it beside the 2025 value; the notice doesn't print the assessed value, so multiply by 40% yourself.
The table applies those rules to an illustrative $300,000 home: its assessed value is $120,000, and the county government's share of the tax at its 2025 maintenance and operations rate of 12.063 mills is about $1,448 a year before exemptions.
The Douglas County Board of Education and any city your home sits in levy their own rates on top, so your full bill is higher.
Your 2026 notice shows no estimated tax, only an estimate of what your exemptions save, figured at the previous year's millage rates. The actual tax is set after each governing body, from the Board of Commissioners to the Board of Education and the cities, adopts its millage rate. You can appeal the value, but no appeal changes those rates.
You file in writing with the Douglas County Appraisal Department, which handles appeals for the Board of Assessors. Georgia law counts a written objection that identifies your property as an appeal, and the state publishes a uniform appeal form, the PT-311A, on the Georgia Department of Revenue's form page.
The county takes appeals three ways, plus an after-hours drop box:
The county doesn't accept appeals by fax or email. Questions go to the Appraisal Department at (770) 920-7228.
If someone else signs the appeal for you, such as a relative or an agent, send a signed letter of authorization with it. When you authorize an agent in writing and the county has a copy, the county sends its notices to both you and the agent. If you hire an appeal service, our guide to working with a property tax appeal service covers what you sign and what to forward.
On the PT-311A you choose where the appeal goes if the assessors don't resolve it:
The county's appeal flowchart says the Board of Equalization is chosen by default if you don't pick a route. The county also notes that extra costs or fees may apply to the other options. A homestead can't use the hearing officer route at any value, so a homeowner chooses among the Board of Equalization, arbitration and, with the assessors' consent, Superior Court.
Value means the fair market value is too high. Uniformity means similar homes near yours are valued lower than yours without a clear reason. Taxability and denied exemptions cover property that shouldn't be taxed at all or an exemption the county turned down. You can check more than one ground.
If you'd rather not track the county's letters and deadlines yourself, AppealAlly's Full Service files your appeal and tracks them for you, and you pay only if we win.
On the Board of Equalization route (the default if you don't pick one), the Board of Assessors reviews your appeal first and writes to tell you whether it changed the value, in what the county calls the 30-day letter; if the value changes and you disagree, state law sets 30 days for you to continue the appeal, and it gives the assessors up to 180 days from receiving your appeal for the review (more in counties with heavy appeal volume). Arbitration follows its own steps, starting with the certified appraisal.
During the review, the county's flowchart says, a staff appraiser checks with the owner that the property record card is accurate and looks at the issues the appeal raises.
The letter is a no-change notice or a change notice, and you can also settle by signing an agreement. Our guides to a no-change notice or a new value and what to check before you sign an agreement cover each one.
Your appeal goes to the Board of Equalization on its own. Under Georgia law the no-change notice is itself your appeal to the Board, so you don't file anything else.
If you accept the new value, the county says you don't need to do anything, and the appeal is withdrawn when your time to respond runs out.
If you disagree, tell the Appraisal Department in writing that you're continuing the appeal by the last day printed on the state's change notice, the PT-306-30, which Georgia law sets at 30 days after the notice was mailed; the appeal then goes to the Board of Equalization.
Accepting by silence isn't a signed agreement, though. If you want the revised value covered by the 299(c) hold (Georgia's rule that keeps the assessors from raising a value lowered on appeal for the next two years, explained below), ask the assessors for a written agreement signed by both sides; whether the hold applies to a value you accepted by doing nothing is unclear.
If you and the assessors sign an agreement on the value, the appeal ends on the date you both sign.
The county's appeal process flowchart lays out these steps for Douglas County on one page, and what happens after you file a Georgia appeal covers the statewide timeline in more depth.
Confirm the dates on your county's letter.
The Board of Equalization is a three-member board appointed by the Grand Jury, and all three members must be present and take part in each appeal.
Georgia law sets its schedule: within 15 days of receiving your appeal, the Board sets a hearing date and tells you in writing, and it holds the hearing 20 to 30 days after that notice. Those clocks start when the Board receives the appeal, not when you filed it.
The county's Appraisal page says you'll get the hearing date and time by mail. It recommends that you attend and come prepared to present information supporting your opinion of the home's fair market value.
On the Board of Equalization route, the default, only if the assessors don't resolve your appeal and it goes on to the Board; arbitration and hearing officer appeals have hearings of their own. Georgia law lets you appear in person, through an authorized agent, or both, and the hearing can be held by audio or video only if the appeal administrator allows it and every party agrees.
A Board decision also affects the 299(c) hold. If you neither attend nor give the Board any written evidence of your value, a lower value from that decision carries no hold. Sending written evidence ahead keeps that exception from applying even if you can't be there.
The county carries the burden: under Georgia law, the Board of Assessors must prove its value and the validity of its assessment by a preponderance of the evidence, so your job is to give the Board solid reasons to doubt the county's number.
Either side can ask for the other's witness list and documents, and Georgia law requires the request at least 10 days before the hearing and the documents at least 7 days before it. If you have more than one property under appeal, the Board will hear them together at your request and decide each one separately.
The county's flowchart says the Board's decision goes to you in writing by certified mail. If you agree with it, you don't need to do anything.
If you or the Board of Assessors disagree, state law requires a written petition for review, filed with the assessors within 30 days after the decision is delivered, to take the case to Superior Court; the county's page counts those 30 days from the date the decision is mailed. The county says the owner pays a $25 filing fee to the Clerk of Superior Court, Douglas County.
Confirm the dates on your county's letter.
On appeal, your value can be lowered but cannot be raised above what the assessors set, unless you filed the appeal while a 299(c) hold was in effect on that value. The rule is in O.C.G.A. § 48-5-311(e)(9), and the 299(c) hold is explained in its own section below.
On the Board of Equalization route, the assessors' review ends in one of two letters: a no-change notice, which sends the appeal on to the Board, or a change notice, which gives you a set time, printed on it, to accept the new value or continue the appeal.
If your value is already under a 299(c) hold from an earlier appeal, a new appeal can move it up or down on the evidence, unless both sides agree otherwise in writing.
Send evidence of what your home would sell for, plus anything that shows the county's record of your home is wrong. The Board decides on evidence, and the county recommends coming prepared to support your opinion of value.
The county's Appraisal page tells owners to request a copy of their property record card and check it for accuracy, and it says comparable property values and sales are also available at the Appraisal Department. The card holds what the county has on file for your home. A finished basement that's really unfinished, a bathroom that doesn't exist or the wrong square footage can push the value up, and those errors are simple to document.
Georgia law also lets you ask the assessors for the records behind your value, including their method, the documents they reviewed and the comparable properties they used. They must provide copies within ten business days.
Recent sales of similar homes near yours are direct evidence of market value. Look for homes close to yours in size, age and condition. If similar homes sold for less than the county's value for yours, list each sale beside your home's details and mark where each one sits on a map.
A recent purchase price for your own home is evidence of market value too. Under current Georgia law it no longer caps the next year's value, so treat it as one piece of evidence, not a limit.
If the card rates your home's condition higher than it is, document the gap with dated photos (an aging roof, an old HVAC system, foundation cracks, water damage) and written repair estimates from contractors. The same evidence answers a rising market: a sale of a home with a renovated kitchen and a new roof isn't a match for one with original finishes. And if similar nearby homes are valued lower than yours, that uniformity gap is worth raising whatever the market is doing.
You can submit an appraisal with your appeal if a real property appraiser classified by the Georgia Real Estate Commission and the Georgia Real Estate Appraisers Board signed and certified it. The statute also limits its timing: the appraisal must have been "performed not later than nine months prior to the date of assessment". Georgia values property as of January 1 of the tax year, which the Department of Revenue's appraisal rule calls the assessment date, and the Department's sample Board of Equalization procedures say an appraisal's effective, or "as of", date should fall on January 1 of the year you're appealing or earlier. The nine-month phrase itself can be read more than one way, so ask the Appraisal Department which appraisal dates it accepts before you pay for one. The assessors must consider a qualifying appraisal on request, and Georgia law requires them to tell you within 45 days of receiving it whether they accept it or why they reject it. If you choose arbitration, the county's flowchart says a certified appraisal is required.
The 299(c) hold means that if your appeal lowers your home's value, the assessors can't raise that lower value for the next two years, so it's held for the appeal year and the two after it, subject to the statutory exceptions. Under O.C.G.A. § 48-5-299(c), the hold follows a Board, hearing officer, arbitrator or court decision, or a written agreement signed by the assessors and the owner or the owner's authorized agent.
A no-change result starts no hold. HB 581 removed the old rule that held an unchanged value too, effective January 1, 2025, and how HB 581 changed the 299(c) hold explains the change in detail.
The hold can end early if you file a return at a different value, file a new appeal during the two years, or the assessors find substantial changes or record errors after an on-site inspection. A signed value agreement carries the hold unless both sides waive it in writing.
In dollars, for an illustrative home whose fair market value drops by $40,000 on appeal, the assessed value falls by $16,000 ($40,000 x 40%). At the county government's 12.063-mill rate, that trims the county's share of the bill by about $193 a year before exemptions, and the school and any city rates apply to the lower value too. If the lower value holds for this year and the next two, subject to the statutory exceptions, the county share alone comes to an estimated $579 over three years.
Douglas County's 2025 county rate did not rise 33.26%. The county's own records show its 2025 net maintenance and operations rate stayed at 12.063 mills, the same as 2024.
The 33.26% figure came from the county's 2025 Notice of Property Tax Increase, which announced a tentative rate of 15.763 mills, 33.26% above a rollback rate of 11.829 mills. That proposal, up about 3.7 mills from the year before, was not the rate the county ended up with: its 2026 tax digest and five-year levy history lists the 2025 rate at 12.063 mills.
Each year the county must compute a rollback rate, the rate that would raise the same revenue as the year before if no property had been reassessed, and a rate above it is announced as a tax increase. That's why the county's release posted on July 31, 2026 said that simply keeping 12.063 mills would still mean a percentage increase in property taxes, because property values had gone up.
For 2026, that release proposed keeping 12.063 mills. The county's later notice proposed 12.035 mills instead, 0.453 mills above an 11.582-mill rollback rate, which the county described as a 3.91% increase over the rollback rate. It put the increase at about $61 for a $350,000 home and about $63 for non-homestead property of the same value, and it set adoption for a special called meeting in late September 2026. The county's millage page didn't yet show an adopted 2026 rate when the sources for this article were read, so go by the rates printed on your 2026 bill.
Your due date is printed on your tax bill: the Douglas County Tax Commissioner's office says bills are mailed in early autumn to the owner of record as of January 1 and are due 60 days after the mailing, so any date you hear before the bill arrives is an estimate. Our guide to Georgia property tax due dates covers installments and what happens to your bill while an appeal is open.
The office's pages give that rule rather than a calendar date and list no installment schedule, so your bill is where to find the exact date and whether the tax is split into installments. The Georgia Department of Revenue's Douglas County page adds that Georgia law requires at least 60 days from the bill's postmark before interest starts.
For 2026, bills can't be final until each governing body adopts its rate, and the county set its own vote for late September. The Tax Commissioner's office says current-year taxes can be paid online once the bills have been mailed.
A few payment rules from the office's own FAQ page:
If the county sends bills before your appeal is decided, you get a temporary bill. In most cases it's based on the lower of last year's final value or 85% of this year's value, and it tells you that a refund or an additional bill may follow once the appeal is decided.
If the final value lowers your taxes, Georgia law requires the tax commissioner to refund the difference with interest, normally within 60 days of the final decision; if it raises them, you get an adjusted bill and have 60 days from its postmark to pay.
Homestead and other exemptions are separate from an appeal, and you file them yourself with the Tax Commissioner's office. Georgia law sets the homestead application deadline at the last day to appeal your annual notice, and Douglas County's 2026 notice puts both at 45 days from the date the notice was mailed, as long as you met the age and ownership rules as of January 1. The office's own page still shows an estimated April 1 cutoff, so go by your notice. AppealAlly handles property tax appeals only, not exemption applications; other ways to lower a Georgia property tax bill covers exemptions and more.
The Tax Commissioner's office is at the same Fairburn Road address as the appraisal annex. Its phone is (770) 920-7272, and it's open Monday to Friday, 8 a.m. to 4:30 p.m., closed from noon to 1 p.m.
Confirm the due date on your tax bill.
Each of these can sink an appeal or cost you the 299(c) hold.
You can't appeal the millage rate or the size of the bill. The appeal is about the county's fair market value (or uniformity, taxability or an exemption), so your evidence should show what the home would sell for.
If the assessors change your value and you disagree, send your written continuation by the last date printed on the change notice; Georgia law requires it within 30 days of the notice's mailing. After that, the county treats the appeal as withdrawn at the new value.
If your appeal reaches the Board of Equalization, attend or send written evidence of your value. Without either, a lower value from the Board's decision carries no 299(c) hold.
Confirm the dates on your county's letter.
