Taxes & Insurance in Smyrna
Cobb County's property tax rate runs lower than Gwinnett's, consistent with the base record's own note that Cobb sits among the lower-rate metro-Atlanta counties -- but a Smyrna-specific city millage on top of the county rate was not confirmed this session, and Cobb's 2026 millage structure includes a district-specific component worth understanding.

Cobb County's effective property tax rate was cited at 0.67%, with the median homeowner paying $2,720/year on a home worth $407,200 (Ownwell, retrieved 2026-08-22) -- consistent with the base record's own note that Cobb sits among the lower-rate metro-Atlanta counties (roughly 0.67%-0.69%), and meaningfully below Gwinnett County's 0.95%-0.98% effective rate cited for Duluth elsewhere in this batch.
Cobb's 2026 millage has a district-specific component -- read carefully before assuming it applies citywide
Cobb County set its 2026 millage rates with a General Fund M&O rate of 8.46 and a Fire millage of 2.97, plus a separate Cumberland Special Services District II millage of 2.45 (Cobb County government, retrieved 2026-08-22) -- that Cumberland district millage applies specifically within the Cumberland Community Improvement District (the area around Battery Atlanta and Truist Park, per the moving topic's geographic clarification), not necessarily to all Smyrna properties. 2026 Cobb County property tax bills were issued with an October 15, 2026 due date.
A Smyrna-specific city millage was not confirmed this session
As an incorporated city, Smyrna residents typically pay city-level millage on top of the Cobb County rate -- but a specific, current Smyrna city millage figure was not independently confirmed this session. This is disclosed explicitly, the same gap pattern found for Duluth's city millage elsewhere in this batch; check the Cobb County Tax Commissioner or City of Smyrna directly for a parcel-specific estimate.
Georgia's flat income tax and statewide insurance costs apply the same as elsewhere in this batch
Georgia's state income tax is a flat 4.99% for 2026, down from 5.19% in 2025 and 5.39% in 2024 under HB 463 (ustax.tools, BlueWave HR, retrieved 2026-08-22) -- a statewide rule, not Smyrna-specific. Homeowners insurance estimates for Georgia varied widely by source and coverage level this session, from roughly $1,480/year up to $4,092/year depending on methodology (MoneyGeek, Insuranceopedia, Insure.com aggregation, retrieved 2026-08-22) -- get a specific quote for any Smyrna address rather than relying on a statewide average.
Key takeaways
- Cobb County's effective property tax rate is 0.67% (median $2,720/yr on a $407,200 home) -- lower than Gwinnett County's 0.95%-0.98% cited for Duluth elsewhere in this batch.
- Cobb's 2026 millage includes a Cumberland Special Services District II component (2.45 mills) that applies specifically within that district, not necessarily citywide in Smyrna -- read district-specific millage carefully rather than assuming it applies to every Smyrna property.
- A Smyrna-specific city millage on top of the county rate was not confirmed this session -- a genuine, disclosed data gap; confirm with the City of Smyrna or Cobb County Tax Commissioner directly.
- Georgia's flat 4.99% income tax (2026) and a wide statewide homeowners-insurance range ($1,480-$4,092/yr) apply the same in Smyrna as elsewhere in this Georgia batch.
