A property tax rate below the state average

Newburyport's FY2026 property tax rate ran $9.26 per $1,000 of assessed value (uniform across property classes), down from FY2025's $9.58 -- genuinely below Massachusetts's statewide average effective rate of 1.00%-1.17%.

Massachusetts's statewide income and sales tax structure

Massachusetts's real flat 5% state income tax rate applies to most Newburyport residents' income, with a real, additional 4% surtax on taxable income above $1,107,750 (a 2022 ballot measure). Massachusetts's uniform 6.25% sales tax, with no local add-on, applies statewide.

A real, disclosed coastal and tidal flood exposure

14.5% of Newburyport properties currently carry flood risk per First Street Foundation data, projected to rise to 16.7% within 30 years. The City of Newburyport's own 2022 Multi-Hazard Mitigation Plan identifies nor'easters, tidal river flooding, and sea-level rise as the city's most relevant hazards; by 2070, the majority of the Downtown Waterfront is projected to see annual inundation. Standard homeowners policies do not cover flood damage -- confirm current, address-specific FEMA flood-zone status and NFIP or private flood-insurance requirements directly for any target property.
