An Atlanta property tax increase almost always traces back to two things working together: the county raised the fair market value on your home, and the taxing authorities set a millage rate above the rollback that would have offset that higher value. Georgia law pegs your assessed value at 40 percent of fair market value, so every bump in what Fulton or DeKalb says your home is worth flows straight into the bill unless the county, city, or school board rolls its rate back to match.1Justia. Georgia Code 48-5-7 – Assessment of Tangible Property You have real tools to push back: homestead exemptions you may not have claimed, and a 45-day window to appeal the assessment itself.
Why Your Bill Went Up
The Fulton County Board of Assessors and the DeKalb County Property Appraisal Department reassess property every year by looking at recent sales of comparable homes near yours. You don’t need to sell or renovate for your value to rise; a neighbor’s higher sale price feeds the model. In metro Atlanta, waves of sales at stronger prices have pushed valuations upward across most ZIP codes.
The second half of the math is the millage rate. Each $1 in millage is $1 of tax per $1,000 of assessed value, and multiple authorities stack their rates: Fulton County, the City of Atlanta, the Atlanta Board of Education, and various special districts each adopt their own.2Georgia Department of Revenue. Property Tax Millage Rates Fulton County alone proposed 9.87 mills in 2025, up from roughly 8.77 the year before.3Fulton County. Notice of Property Tax Increase
Georgia defines a rollback rate as the millage that would bring in the same total revenue as the prior year despite higher property values. A county or school board that wants to adopt a rate above the rollback has to advertise that intent and hold at least three public hearings, one starting between 6:00 and 7:00 p.m. on a weekday.4FindLaw. Georgia Code Title 48 Revenue and Taxation 48-5-32.1 Many Atlanta-area jurisdictions do exactly that, so your bill rises on both ends.
Zoning changes nearby can also shift your value. If land close to you is rezoned to allow commercial or mixed-use development, the assessor may conclude your parcel has a higher “highest and best use,” even if nothing changed inside your fence line.
Homestead Exemptions That Lower the Bill
Homestead exemptions shield part of your assessed value from tax, and most Atlanta homeowners qualify for more than they realize. You’re eligible for the basic exemption if you owned and occupied the home as your primary residence on January 1 of the tax year.5Georgia Department of Revenue. Property Tax Homestead Exemptions The standard statewide exemption under O.C.G.A. § 48-5-44 removes up to $2,000 of assessed value from state, county, and school taxes, with limited exceptions for certain bond levies.6Justia. Georgia Code 48-5-44 – Exemption of Homestead Occupied by Owner It’s modest on its own, but it stacks with the others.
Senior Exemptions
Homeowners aged 62 and older with household income (excluding certain retirement and Social Security amounts) at or below $10,000 can claim up to $10,000 of assessed value exempt from school taxes under O.C.G.A. § 48-5-52. Homeowners 65 and older with the same income cap get a separate $4,000 exemption from county ad valorem taxes under O.C.G.A. § 48-5-47.5Georgia Department of Revenue. Property Tax Homestead Exemptions For many retirees, the school-tax piece erases the largest single line on the bill.
Disabled Veteran Exemption
Veterans the U.S. Department of Veterans Affairs rates 100 percent disabled, or who meet statutory criteria for loss of limbs or eyesight, qualify for an exemption of at least $32,500 under O.C.G.A. § 48-5-48, or the maximum federal housing grant amount if higher.7FindLaw. Georgia Code Title 48 Revenue and Taxation 48-5-48 An unmarried surviving spouse can continue the exemption. You’ll need a VA letter documenting the disability rating.
Fulton County’s Floating Exemption
Fulton County offers a floating homestead exemption that caps growth in the taxable base at 3 percent or the Consumer Price Index, whichever is lower.8Fulton County. Homestead Exemption Guide The cap applies to the base value, not to the final bill, so your taxes can still rise faster than 3 percent if millage rates go up.9Fulton County Board of Assessors. Exemptions In a year when the county says your market value jumped 15 percent, though, the floating exemption keeps the taxable base from following it all the way up.
When to Apply
The traditional filing deadline is April 1 of the tax year, and Georgia also allows applications up to 45 days after you receive the annual assessment notice.5Georgia Department of Revenue. Property Tax Homestead Exemptions Once an exemption is approved, it renews automatically as long as you keep living in the home. Notify the county tax commissioner only if something changes, like a move or converting the property to a rental.
How to Appeal the Assessment
If the value on your Annual Notice of Assessment looks too high, the appeal is your most direct route to a smaller bill. Fulton and DeKalb typically mail notices in late spring or early summer, and you have 45 days from the date printed on the notice to file.10Georgia Department of Revenue. PT-311A Appeal of Assessment Form Miss the window and the value stands for the year.
Build the Evidence First
Comparable sales do the heavy lifting. Pull three to five recent sales of homes similar to yours in size, age, and condition from the same neighborhood, and show that they sold for less than the county’s number on your home. Add photos of anything that pulls your value below those comps: aging roof, dated kitchen, foundation cracks, proximity to a loud corridor. If you refinanced recently and have an independent appraisal, submit it; a licensed appraiser with no stake in the tax outcome is persuasive evidence even though the county isn’t required to accept it.
File the PT-311A
Georgia uses a uniform appeal form, the PT-311A, available on the Georgia Department of Revenue site and county assessor sites.10Georgia Department of Revenue. PT-311A Appeal of Assessment Form You’ll fill in your parcel identification number, state your own opinion of fair market value, and pick an appeal path. The hearing officer option is limited to non-homestead commercial property over $500,000, so residential homeowners generally choose the Board of Equalization.11Georgia House of Representatives. Summary of Appeal Process O.C.G.A. 48-5-311 Submit through the county’s online portal, by hand, or by certified mail with return receipt, and keep copies of everything. Losing an appeal because you forgot to sign the form is a bad way to lose a year.
What Happens Next
The Board of Tax Assessors has up to 180 days to act. It may lower the value, hold firm and send the case to the Board of Equalization, or let the clock run out. If the board doesn’t respond within 180 days and you stated a value on your form, your stated value becomes the assessed value for that year by default.12Justia. Georgia Code 48-5-311 – Creation of County Boards of Equalization That outcome happens more often than people expect in heavy appeal years. If the case reaches the Board of Equalization, you’ll present your evidence to a three-member citizen panel and the county appraiser will defend the number. Either side can take the written decision to Superior Court within 30 days of mailing.
You Still Owe Taxes While Appealing
An open appeal doesn’t pause your tax bill. Fulton County issues a temporary bill based on the higher of your self-reported value or 85 percent of the assessor’s proposed value, and it’s due by the normal deadline.13Fulton County Taxes. Due August 15 If the appeal reduces your value, you get a refund of the overpayment.
Atlanta homeowners juggle two due dates. City of Atlanta taxes are typically due August 15, and Fulton County taxes October 15.13Fulton County Taxes. Due August 15 DeKalb County generally collects between mid-August and mid-November. Missing a deadline triggers penalties and interest, and in counties with 900,000 or more residents, which includes Fulton, late amounts accrue interest at the rate set under O.C.G.A. § 48-2-40 plus an additional 1 percent per month on balances over $1,000, up to the statutory cap.14Justia. Georgia Code 48-5-24 – Payment of Taxes to County
What a Higher Bill Does to Your Mortgage
If you pay taxes through escrow, which most Atlanta homeowners do, a higher bill creates an escrow shortage, and the servicer raises your monthly payment to cover it. Federal rules under RESPA require servicers to run an escrow analysis once every 12 months and send you an annual statement within 30 days of completing it.15Consumer Compliance Outlook. Top Federal Reserve System Compliance Violations Under RESPA and Regulation X A shortage can be spread over the next 12 months, so a $1,200 tax increase adds about $100 a month to your payment, often several months after the tax itself was paid. Reviewing the escrow statement as soon as it arrives gives you time to budget and, if the increase was driven by assessment, to put the next year’s appeal on the calendar.
The SALT Deduction, If You Itemize
Property taxes you pay are deductible on your federal return under 26 U.S.C. § 164, but only if you itemize. For the 2026 tax year, the combined state and local tax deduction (property, state income, and local taxes together) is capped at $40,400 for single filers and married couples filing jointly, and $20,200 for married filing separately, with the cap rising roughly 1 percent per year through 2029 before dropping back to $10,000 in 2030 unless Congress changes the law.16Office of the Law Revision Counsel. 26 USC 164 – Taxes If your total itemized deductions don’t beat the standard deduction, the SALT cap doesn’t affect you because you’d take the standard amount anyway. Running the numbers both ways before filing is worth the few minutes.
