The Fulton County GA property tax rate is layered: the county government itself levies 8.87 mills for 2025, but school district and city millage rates stack onto the same bill, pushing combined rates above 32 mills in cities like Alpharetta.1Fulton County. Fulton Holds Millage Rate at 8.87 Mills for 2025 No single number tells you what you owe, because what shows up in your mailbox depends on which school district and which city (if any) you fall inside.
How Millage Rates Turn Into Dollars
Georgia doesn’t tax the full market value of your home. Under state law, taxable property is assessed at 40% of fair market value.2Justia. Georgia Code 48-5-7 – Assessment of Tangible Property A home the Board of Tax Assessors values at $400,000 has an assessed value of $160,000. That assessed value is what every millage rate on your bill applies to.
One mill equals one dollar of tax for every $1,000 of assessed value.3Georgia Department of Revenue. Property Tax Millage Rates So a combined rate of 32 mills applied to a $160,000 assessed value produces $5,120 in annual property tax before exemptions. Change the assessed value or any of the stacked rates and the whole figure moves.
The Three Layers On Your Bill
Most Fulton County tax bills reflect three separate taxing authorities, each of which sets its own rate through its own public hearings.4Fulton County. Property Taxes
The county government rate is 8.87 mills for 2025, held flat from the prior year.1Fulton County. Fulton Holds Millage Rate at 8.87 Mills for 2025 This piece funds county-wide services like public safety, infrastructure, and parks, and it applies to every property owner in the county regardless of city.
The school district rate is the biggest chunk for most homeowners. Properties in the Fulton County School District carry a school millage of roughly 18.50 mills. Properties inside the City of Atlanta fall under Atlanta Public Schools instead, with its own separate rate.3Georgia Department of Revenue. Property Tax Millage Rates School taxes typically account for more than half of a Fulton County tax bill, which is why school board millage decisions matter more to your bottom line than county decisions do.
The city rate applies only if you live inside an incorporated municipality. Alpharetta levies about 4.731 mills. Other Fulton cities set their own figures based on their own budgets. If your home is in unincorporated Fulton County, there is no city line on your bill at all, though the county then handles municipal-type services directly.
Two homes with identical market values can produce tax bills that differ by thousands of dollars based solely on their city and school district. That is why a single county-wide number doesn’t tell you much on its own.
A Worked Example: Alpharetta Home At $400,000
Running the numbers for a specific case makes the stacking visible. Take a $400,000 home in Alpharetta:
- Assessed value: $400,000 × 40% = $160,000
- Fulton County (8.87 mills): $1,419
- Fulton County Schools (18.50 mills): $2,960
- City of Alpharetta (4.731 mills): $757
- Total before exemptions: approximately $5,136
The school line alone is more than twice the county line. Homestead exemptions, discussed below, would then cut the assessed value against each authority before the final bill is calculated.
Exemptions That Reduce What You Pay
The basic homestead exemption is the one most Fulton homeowners should claim. It reduces assessed value by $30,000 for county taxes and $2,000 for school taxes. Inside Atlanta city limits, it also removes $30,000 from city operations, city parks, and city school taxes.5Fulton County Board of Assessors. 2026 Homestead Exemption Guide To qualify you must own and occupy the home as your primary residence on January 1 of the tax year. The traditional deadline is April 1, though Georgia now allows filing through the end of your 45-day assessment appeal window.6Georgia Department of Revenue. Property Tax Homestead Exemptions Once granted, it stays in place as long as you keep living there.
Fulton stacks additional exemptions for older and disabled homeowners, keyed to age and income:
- Age 65, no income test: $50,000 off county operations, plus a separate $10,000 off Fulton County school taxes if you have held a Fulton homestead for at least five years.
- Age 65 with income up to $10,000 on the Georgia return: $4,000 off all county ad valorem levies.
- Age 65 or disabled with income up to $30,000: $54,000 off county school operations and bonds (not available inside Atlanta).
- Age 65 with income up to $39,000: a homestead freeze that locks assessed value at the base year for county operations and bonds, plus Atlanta city operations, bonds, and parks for Atlanta residents.
- Age 70 or disabled with income limited to the Social Security maximum: full value exemption on Fulton County operating and bond levies.
All of these come from Fulton County’s 2026 Homestead Exemption Guide.5Fulton County Board of Assessors. 2026 Homestead Exemption Guide The age 70 full value exemption can wipe out the county portion entirely for qualifying homeowners.
Disabled veterans rated 100% service-connected (or compensated at the 100% rate for individual unemployability) can receive an exemption of $50,000 or more on their homestead. It applies against all ad valorem taxes: county, city, school, and state.7Justia. Georgia Code 48-5-48 – Exemptions for Disabled Veterans Surviving spouses may also qualify as long as they do not remarry. Documentation from the U.S. Department of Veterans Affairs is required, so the Board of Assessors is the right first call.
Deadlines And What Late Payment Costs
Fulton County mails tax bills in July. City of Atlanta taxes are due August 15; Fulton County taxes are due October 15.8Fulton County Tax Commissioner. Fulton County Taxes – Home Interest on delinquent property taxes runs at the bank prime loan rate plus 3%, accruing monthly.9Justia. Georgia Code 48-2-40 – Rate of Interest on Past Due Taxes Because Fulton’s population exceeds 900,000, an additional 1% per month accrues on any unpaid balance above $1,000, with the combined rate capped at 12% per year or the standard statutory rate, whichever is higher.10Justia. Georgia Code 48-5-24 – Payment of Taxes to County With prime recently in the 6.5% to 7.5% range, total annual interest on a delinquent Fulton bill can easily reach double digits.
Unpaid taxes also lead to a fi. fa. (tax lien execution) and eventually to a tax sale. After a tax sale, the former owner has 12 months to redeem the property by paying the purchase price, a statutory premium, and all subsequent taxes.11Justia. Georgia Code 48-4-40 – Persons Entitled to Redeem Land Calling the Tax Commissioner’s office before a lien issues is far cheaper than unwinding a sale later.
If The Assessed Value Looks Too High
The millage rates are set by elected bodies and you can’t negotiate them, but you can challenge the assessed value they get applied to. Georgia gives property owners 45 days from the mailing date of the assessment notice to file a written appeal with the Board of Tax Assessors.12Justia. Georgia Code 48-5-311 – Creation of County Boards of Equalization Miss the 45 days and the value stands for the year.
Strong appeals rest on specifics: comparable sales in your neighborhood below the assessor’s figure, factual errors in the property record (wrong square footage, phantom bedrooms), or a uniformity argument that similar homes are assessed lower. An independent appraisal is the single strongest piece of evidence; neighborhood comp sales cost nothing and also work.
The Board of Tax Assessors has 180 days to respond. If they don’t respond in that window, the value you asserted on your appeal becomes the assessed value for the year by default.12Justia. Georgia Code 48-5-311 – Creation of County Boards of Equalization If they stand by their number, the case goes to the county Board of Equalization for a hearing within 30 days of notice. You can request the county’s documents and witness list at least ten days before the hearing, and vice versa.
One trap to know about: an appeal does not pause your tax deadline. Georgia requires you to pay the undisputed portion on time. If you win and overpaid, you get a refund.
Finding Your Own Rate And Bill
The Fulton County Tax Commissioner’s online portal lets you search for your bill by parcel ID, account number, or street address, and the bill itself shows the fair market value, assessed value, all applied exemptions, and a line-by-line breakdown of every taxing authority’s millage rate.4Fulton County. Property Taxes That breakdown is where you confirm your actual combined rate rather than relying on an average. If a number looks wrong, note which authority set it: the Tax Commissioner collects the money, but the Board of Assessors is the office that determines value and handles exemptions.
