Taxes in Kennesaw
Kennesaw residents pay Georgia's flat state income tax alongside Cobb County's own multi-layer property tax structure -- county, school district, and (inside city limits) City of Kennesaw municipal millage -- a genuinely more layered picture than a single-county, single-city market, disclosed honestly rather than collapsed into one number that isn't there.

Learn moreGeorgia's flat state income tax
Georgia levies a flat individual income tax rate of 4.99% for tax year 2026, per HB 463 (signed May 11, 2026, retroactive to January 1, 2026) -- a real, ongoing cost for residents relocating from a no-income-tax state. Further statutory cuts toward a 3.99% floor remain on the books but are contingent on the state meeting annual revenue-growth triggers, and no further cut beyond 4.99% is currently confirmed.
Cobb County's precisely sourced county-level millage
Cobb County's 2026 General Fund Maintenance & Operations millage held flat at 8.46 mills, with a separate 2.97-mill Fire Fund levy. Homestead-exemption holders see no change in their county M&O bill for 2026 absent a change to the property itself. This dataset's own Georgia state record (georgia.js) cites Cobb among Georgia's lower-effective-rate metro-Atlanta counties, in a roughly 0.67%-0.69% range (AppealAlly) -- a useful directional proxy, though not independently re-verified as Kennesaw-specific.
A genuine multi-layer structure -- county, school district, and city millage
A specific Kennesaw parcel's total property tax bill layers the county millage above onto a separate Cobb County School District millage and, for properties inside Kennesaw's incorporated city limits specifically, the City of Kennesaw's own municipal millage. A single, precise, current COMBINED effective rate for Kennesaw was not resolved to one verified figure this research pass -- recorded as null in this dataset's metrics rather than guessed, consistent with how this project's other Cobb/Fulton-area satellite records (Marietta, Alpharetta, Sandy Springs, Roswell in georgia-atlanta-satellites-1.js) handled the same type of gap. Confirm the exact combined rate for a specific parcel directly with the Cobb County Tax Commissioner and the City of Kennesaw.
No local income tax; standard Georgia sales tax structure
Georgia has no local (county or city) personal income tax layered on top of the state's flat rate. Georgia's state sales tax base rate is 4%, with counties and cities adding local-option taxes on top -- confirm Cobb County's and the City of Kennesaw's current combined rate directly for accurate budgeting.
Key takeaways
- Georgia's flat state income tax is 4.99% for 2026 (HB 463) -- a real, ongoing cost, unlike no-income-tax states featured elsewhere in this dataset. Further cuts toward a 3.99% floor remain contingent on unmet state revenue triggers as of this research.
- Cobb County's 2026 millage held flat at 8.46 mills (General Fund M&O) plus 2.97 mills (Fire) -- this dataset's Georgia state record cites Cobb among the state's lower-effective-rate metro-Atlanta counties (~0.67%-0.69%), a directional proxy rather than a Kennesaw-specific figure.
- A single, precise, Kennesaw-specific COMBINED effective property tax rate (county + Cobb County School District + City of Kennesaw municipal millage) was not resolved this research pass -- recorded as a genuine gap, consistent with how this dataset handled the same issue for Marietta, Alpharetta, Sandy Springs, and Roswell.
- No local personal income tax on top of the state's flat rate; Georgia's state sales tax base is 4%, with county/city local-option additions -- confirm Cobb County's and Kennesaw's current combined rate directly.
