Learn moreA moderate property tax position
Decorah's median effective property tax rate ran approximately 1.37% (Ownwell) -- above the national median of 1.02% but below Iowa's own statewide median of 1.54%; the median annual tax bill ran approximately $3,194 (base record).
Iowa's real, current flat income tax
Iowa's flat individual income tax rate ran a real, current 3.8% for 2026, with full Social Security and qualifying retirement-income exemptions for taxpayers 55+ -- genuinely relevant given Decorah's own above-threshold senior population share (base record).
Insurance costs shaped by real flood exposure
No Decorah-specific homeowners-insurance premium was found this pass; Iowa's statewide average ran approximately $2,527-$2,664/year (2026), up a real, disclosed 28% in 2025 alone -- a cost genuinely worth confirming given Decorah's documented Upper Iowa River flood history (base record).
Key takeaways
- Decorah's effective property tax rate (~1.37%) runs between the national and Iowa statewide medians.
- Iowa's flat 3.8% income tax and full retirement-income exemptions for 55+ apply statewide.
