Property Taxes in Atlanta
Property taxes are a genuinely complicated, two-county question for Atlanta homeowners, and the base Atlanta record already discloses that the effective rate could not be resolved to one authoritative figure this session (sources cited roughly 0.86%-1.08% for Fulton County). A fresh pass reinforced that same disagreement -- one aggregator's own page title cited 0.88% for Fulton County while its body text cited 1.05% -- and surfaced a real, recent, statewide structural change worth understanding: Georgia's 2025 floating homestead exemption reform.

Fulton County maintained its general-fund millage rate at 8.87 mills for 2026, per county budget reporting. A total property tax bill combines that county rate with a school-district rate and, inside city limits, a City of Atlanta rate -- one illustrative combined calculation cited roughly 34.37 total mills (8.87 county + 18.50 school + 7.00 city). On the effective-rate question specifically, sources disagreed: one 2026 aggregator's page title cited Fulton County's median effective property tax rate at 0.88%, while the same aggregator's body text cited 1.05% -- an internal inconsistency layered on top of the wider 0.86%-1.08% range already disclosed in the base Atlanta record. On a $400,000 home, actual bills were cited as ranging from roughly $4,670 in unincorporated Fulton areas to more than $6,100 inside Atlanta specifically, reflecting the added city-rate layer.
DeKalb County: A Real, Separate Rate Structure
For the smaller DeKalb County portion of Atlanta, one source cited a 4.379 mill DeKalb County rate as the highest among metro counties, describing it as having remained unchanged since 2015 even as rising assessments pushed actual bills higher year over year. This DeKalb millage figure is not directly comparable to Fulton's 8.87-mill county figure without knowing exactly which specific fund or levy each number represents -- confirm the full, current combined millage for a specific DeKalb-side Atlanta address with the DeKalb County Tax Commissioner rather than comparing these two headline numbers directly.
Georgia's 2025 Floating Homestead Exemption: A Real, Recent Reform
Georgia's House Bill 581, approved by voters in a November 2024 statewide referendum and effective in 2025, created a statewide floating homestead exemption that caps taxable-value growth on a homesteaded property to the inflation rate -- the gap between a home's rising market value and its inflation-adjusted assessed value becomes the exemption, and it grows as that gap widens. Counties, cities, and school districts could initially opt out by March 1, 2025, but a 2026 follow-up law (the Georgia HOME Act, Senate Bill 33) made the inflation cap mandatory statewide starting in 2027, ending the local opt-out option. This is a genuinely new, still-unfolding structural change to how Georgia homeowners' assessed values grow, distinct from -- and layered on top of -- the standard homestead exemption.
File the Standard Homestead Exemption by April 1
Separate from the HB 581 floating exemption, Fulton and DeKalb homeowners must file a standard homestead exemption application by April 1 of the year after taking ownership for it to apply to that year's tax bill -- late applications are processed for the following year instead. Fulton County accepts applications online (fultonassessor.org) or in person at any of six Board of Assessors offices; DeKalb accepts applications online from January through April 1, or in person year-round with appointments encouraged.
Confirm Your Actual Bill Directly
Given the disclosed disagreement on effective rates (0.86%-1.08% in the base record, with this pass surfacing an internally inconsistent 0.88%/1.05% figure from a single aggregator) and the real, separate DeKalb rate structure, no single number in this file should be treated as a specific property's actual tax bill. Confirm the current combined millage rate and the property's actual assessed value directly with the Fulton County Board of Assessors or DeKalb County Tax Commissioner, depending on which county the address falls in.
Key takeaways
- Fulton County's general-fund millage held at 8.87 mills for 2026; a total bill layers in a school-district rate and, inside city limits, a City of Atlanta rate -- one illustrative combined total ran about 34.37 mills.
- Effective-rate sources disagreed, including within a single aggregator (0.88% in a page title vs. 1.05% in its own body text) -- consistent with the base record's already-disclosed 0.86%-1.08% range. No single figure should be treated as settled.
- DeKalb County's cited 4.379-mill rate (described as the highest among metro counties, unchanged since 2015) is not directly comparable to Fulton's 8.87-mill figure without confirming which specific levy each number covers.
- Georgia's 2025 floating homestead exemption (HB 581, approved by voters in November 2024) caps assessed-value growth on homesteaded properties to the inflation rate; a 2026 follow-up law (SB 33) makes this mandatory statewide starting 2027, ending the prior local opt-out.
- The standard homestead exemption must be filed by April 1 of the year after taking ownership (Fulton or DeKalb Board of Assessors, depending on the property) to apply to that year's bill.
