Minnesota's 4-bracket income tax, with no local piggyback
Minnesota's real, progressive state income tax (5.35%-9.85% over approximately $193,240 for single filers, 2026) applies in Cottage Grove exactly as it does statewide -- with no local piggyback layer, but a genuine outlier in still taxing Social Security above an income-based exemption.
Minnesota's real 2025 insurance rate spike
No Cottage Grove-specific insurance premium was found this pass, but Minnesota's homeowners insurance rose a real, current 34% in 2025 alone -- the steepest of any state nationally, driven overwhelmingly by hail -- with statewide premiums running $2,200-$3,654/year depending on source.
