Brookhaven's FY2026 millage rate was set at 3.850 mills, up from 2.740 mills in 2025 -- the first increase since the city's December 2012 incorporation (base record). This is reported as either a 40.5% increase (against the prior nominal rate) or a 47% increase (against the rollback rate), both framings disclosed rather than one chosen silently. For a homesteaded $800,000 property, this adds roughly $394.56/year; for a non-homestead $1.575M property, roughly $764.46/year.
DeKalb County and school-district layers apply on top, not fully resolved this pass
As with Dunwoody elsewhere in this dataset (also DeKalb County), DeKalb County's own millage and DeKalb County Schools millage apply on top of Brookhaven's city rate. A precise, current combined total specific to Brookhaven was not resolved this pass -- Dunwoody's record in this dataset cites a genuine cross-source spread for DeKalb County's effective rate (roughly 0.95%-1.22%) as the closest available reference point.
Georgia's flat state income tax and homestead rules apply the same way here as statewide
Georgia's flat state income tax rate is cited at 4.99% for 2026 (one source cites 5.19%, a disclosed discrepancy). Georgia's statewide homestead exemption and any additional DeKalb County-specific exemptions apply to Brookhaven homeowners exactly as they would elsewhere in the county.
Homeowners insurance: a real, wide, unreconciled range
Homeowners insurance is cited in a $1,600-$3,200/year range depending on home age, roof condition, and coverage level, against a statewide Georgia average cited at roughly $2,286-$2,323/year. No single precise Brookhaven-specific figure was found and reconciled this pass -- use the range as a planning band, not a point estimate.
