A genuinely low nominal rate reflecting high values

Charlestown's estimated FY2026 residential rate ran $5.07 per $1,000 of assessed value (a revaluation-year estimate), down from FY2025's $5.93 -- genuinely low in per-mill terms because Charlestown's property values run high (base record).

Rhode Island's real 2026 income tax and sales tax structure

Rhode Island's graduated income tax tops out at 5.99% (2026), and its flat 7% statewide sales tax carries no local add-ons -- both apply in Charlestown as statewide (base record).

Do not mistake a low rate for a low total tax bill

This record discloses directly that Charlestown's low nominal rate does not imply a low overall property tax burden in dollar terms given the town's elevated home values (base record).

A real, coastal-specific flood-insurance caveat

Rhode Island's favorable statewide homeowners-insurance average does not include flood coverage -- a materially important, separate consideration given Charlestown's coastal position (base record).
