Learn moreA property tax rate below Connecticut's own average
Norwalk's effective property tax rate ran approximately 1.62% (a 23.16 mill rate against Connecticut's 70% statutory assessment ratio) -- genuinely below Connecticut's own statewide average of approximately 1.8%-2.0%, consistent with wealthier Fairfield County towns carrying lower effective rates on higher assessed values.
A real, ongoing revaluation phase-in
Norwalk's 2025 Grand List reflects Year 3 of a four-year phase-in of the 2023 citywide revaluation (a real, average 35% increase in assessed values citywide) -- bills will continue shifting through the phase-in's completion.
Connecticut's real, graduated income tax
Connecticut's top marginal state income tax rate runs 6.99% (2026) across 7 brackets starting at 2%, applying above $500,000 (single) / $1,000,000 (joint) taxable income. The state's flat 6.35% sales tax carries no local-option add-on, with a 7.75% carve-out on certain luxury goods.
Key takeaways
- Norwalk's effective property tax rate (~1.62%) runs below Connecticut's own statewide average.
- A real, ongoing four-year revaluation phase-in (Year 3 as of the 2025 Grand List) will keep shifting bills.
- Connecticut's 6.99% top income tax rate and flat 6.35% sales tax (no local option) apply statewide.
