Taxes & Insurance in Sag Harbor
Sag Harbor applies New York State's own graduated income tax with no added village income tax, a Suffolk County property tax whose true effective rate on Sag Harbor's own high-value properties likely runs below the county average, and the East End's real, distinctive Peconic Bay CPF transfer tax and elevated coastal insurance exposure.

Learn moreNew York State's graduated income tax, verified with no added village layer
New York State's 2026 income tax runs 9 brackets, 4.0%-10.9%. This record verifies, per this project's own New York manifest research, that Sag Harbor -- like nearly every New York municipality outside NYC and Yonkers -- levies no separate local income tax.
A county-average property tax rate that likely overstates the real Sag Harbor rate
Suffolk County's average effective property tax rate ran 1.7%-1.85%, with a genuinely high median absolute bill ($10,001 on a $539,500 home) -- but the Village of East Hampton's own directly comparable assessment ratio (just 2%-4% of market value) suggests Sag Harbor's own true effective rate on market value likely runs meaningfully lower, a real, disclosed research gap this record does not paper over with an invented Sag Harbor-specific figure.
The Peconic Bay CPF: a real, distinctive East End-only transfer tax
A real, buyer-paid 2.5% combined transfer tax (2% original CPF plus a 0.5% Community Housing Fund Tax added April 1, 2023) applies to Sag Harbor purchases via both the Town of Southampton and the Town of East Hampton, with allowances of $400,000 (improved) or $100,000 (unimproved) -- and NO allowance at all above $2 million.
Elevated coastal homeowners-insurance exposure
New York's statewide average homeowners premium runs $1,554-$1,683/year, but this project's own new-york.js record separately documents nearby Montauk's ZIP code (11930) as the state's single most expensive, at roughly $3,332/year -- real, directly relevant East End context for Sag Harbor's own bay-front exposure.
Key takeaways
- New York State's 4.0%-10.9% graduated income tax applies with NO separate Sag Harbor village income tax.
- Suffolk County's 1.7%-1.85% average effective property tax rate likely overstates Sag Harbor's own true rate.
- The Peconic Bay CPF transfer tax (2.5% combined) is a real, distinctive East End-only buyer cost, with no allowance above $2 million.
- Coastal homeowners insurance runs well above New York's statewide average in this region.
