Taxes in Decatur
Decatur's tax picture combines Georgia's statewide flat income tax with a genuinely distinctive local wrinkle: the city is served by its own independent school system, City Schools of Decatur, which in February 2025 opted out of a new statewide property-tax cap that many other Georgia districts adopted -- a real, sourced, locally debated decision worth understanding before budgeting long-term property tax growth here.

Learn moreGeorgia's flat state income tax and DeKalb sales tax
Georgia's state personal income tax is a single flat rate, now 4.99% for tax year 2026 under HB 463 (signed May 2026, accelerating a prior multi-year phase-down). DeKalb County's combined sales tax rate is 8.0% (4.0% state plus 3.0% DeKalb County local rate), per 2026 aggregator data -- a modest add-on relative to Georgia's roughly 6%-9% statewide range.
DeKalb County's effective property tax rate, and a real local offset
SmartAsset cites DeKalb County's effective property tax rate at 0.96% of home value for 2026 -- a figure the base record for Decatur left unresolved pending verification, now sourced here. DeKalb County's total millage rate combines several layers (a 12.42-mill general-and-hospital-fund rate cited as part of a combined 20.81-mill total); a typical DeKalb homeowner is cited paying around $3,586/year on a $375,400 median county home value. DeKalb County is also unusual in imposing EHOST (Equalized Homestead Option Sales Tax), a 1% local sales tax specifically dedicated to offsetting school property taxes for qualifying homestead owners -- one of the primary reasons DeKalb homestead owners pay meaningfully lower effective rates than the county's nominal millage would suggest on its own.
City Schools of Decatur's distinctive HB 581 opt-out
Georgia's HB 581, a statewide floating homestead exemption effective 2025, caps annual taxable-value growth on homesteaded property at the inflation rate -- but allows local taxing authorities (counties, cities, school districts) to opt out year-by-year through 2026-2029. The Decatur School Board formally opted OUT of HB 581 at its February 11, 2025 meeting, following public hearings -- meaning the City Schools of Decatur portion of a Decatur homeowner's tax bill is NOT subject to that inflation-rate assessment cap. A board member argued that not opting out risked forcing teacher-job cuts within three years, reflecting the real fiscal tradeoff a small, high-performing, geographically fixed district faces under a statewide cap designed with larger, more elastic tax bases in mind. Separately, Fulton County (relevant for comparison, not for Decatur directly) also opted out district-wide, while roughly two-thirds of Georgia counties by count -- representing nearly 83% of the state's population -- saw at least one taxing authority opt out for 2026.
A 2027 statutory change will eventually override local opt-outs
Georgia's 2026 HOME Act (Senate Bill 33) makes the HB 581 inflation-rate assessment cap MANDATORY for all counties, cities, and school districts starting in 2027, ending the local opt-out option -- meaning City Schools of Decatur's current opt-out status is a temporary, not permanent, local policy choice, and its property-tax growth trajectory will converge with statewide rules from 2027 onward pending any further legislative change.
Georgia's retirement income exclusion is a real consideration for older buyers
Georgia residents 65 and older can exclude up to $65,000 per person of qualifying retirement income (pensions, IRA/401(k) distributions, interest, dividends, capital gains, and limited earned income) from state income tax, with a smaller $35,000 exclusion for ages 62-64; Georgia does not tax Social Security benefits at all. See retiring for the fuller picture.
Key takeaways
- Georgia's flat state income tax is 4.99% for 2026 (HB 463); DeKalb County's combined sales tax rate is 8.0% (4.0% state + 3.0% county).
- DeKalb County's effective property tax rate is cited at 0.96% (SmartAsset) -- resolving the gap the base record left open -- with a typical countywide bill around $3,586/year on a $375,400 median value; DeKalb's 1% EHOST sales tax specifically offsets school property taxes for qualifying homestead owners.
- City Schools of Decatur formally opted OUT of the statewide HB 581 floating homestead exemption in February 2025, meaning its share of a Decatur tax bill is not subject to that inflation-rate assessment-growth cap -- a real, sourced, locally debated decision distinct from how many other Georgia districts handled the same law.
- A 2027 state law (SB 33 / HOME Act) will make the assessment cap mandatory statewide regardless of local opt-outs, so Decatur's current exception is temporary rather than a permanent local policy.
- Georgia excludes up to $65,000 per person (age 65+) of qualifying retirement income from state tax and does not tax Social Security at all -- a real advantage for retiring buyers; see retiring and taxes.
