Learn moreA property tax bill substantially below the state average
Chelsea's FY2026 residential rate is $11.49 per $1,000 of assessed value (an effective 1.149% rate, a slight decrease from FY2025's $11.51). Applied against Chelsea's comparatively affordable typical home value, this implies an approximate $5,568 annual bill -- genuinely, substantially below Massachusetts's own $7,838 statewide average (base record).
A real, disclosed nuance: falling rate, but not necessarily falling bills
Chelsea's own reporting notes that because property valuations rose, actual tax bills are not necessarily decreasing even as the headline rate ticks down slightly -- a real, honest nuance this record discloses rather than oversimplifies (base record).
A real, disclosed residential exemption and split tax rate
Chelsea has adopted both a residential exemption and a split tax rate for FY2026, both of which shift real value toward owner-occupants relative to the headline rate alone (base record).
Massachusetts's statewide tax structure applies identically
Massachusetts's real flat 5% income tax, its 4% surtax above $1,107,750 of taxable income, and its 6.25% single-rate sales tax with no local add-on all apply in Chelsea exactly as documented statewide -- see massachusetts.js.
