Learn moreA genuinely low, mill-rate-derived property tax rate
Westport's real FY2026-27 mill rate of 13.2 -- down roughly 30% from the prior year's 18.86 after a town-wide revaluation -- computes to an effective property tax rate near 0.92% of market value, genuinely low for Connecticut.
A low rate does not mean a low dollar bill
Given Westport's own real, high typical home values (average $2,026,288), a 0.92% effective rate still yields a substantial dollar tax bill (roughly $18,600 on a $2 million home) -- this record discloses that directly.
Connecticut's statewide income and sales tax apply uniformly
Connecticut's top marginal income tax rate runs a real, current 6.99% on income above $500,000 (single) / $1,000,000 (joint), and the state's flat 6.35% sales tax carries no local add-on in Westport or anywhere else.
Key takeaways
- Westport's ~0.92% effective property tax rate (mill rate 13.2) is genuinely low for Connecticut after the 2026 revaluation.
- A low rate on a high-value home still yields a substantial dollar tax bill -- this record discloses that directly.
- Connecticut's 6.99% top income tax and flat 6.35% sales tax apply statewide, including to Westport.
