Webster Groves' own effective property tax rate (1.32%) runs above the 1.02% national median, Missouri's 0.89% statewide average, and St. Louis County's own broader 1.14% overall rate -- reflecting the city's multiple layered local taxing entities (school district, city, library, and Metro Zoo/Museum District).
Missouri's flat income tax applies statewide
Missouri's real, flat 4.0% state income tax (effective January 1, 2026, down from a graduated top rate of 4.7%) applies in Webster Groves exactly as it does statewide -- see missouri.js for the full phase-down mechanism.
Rising statewide insurance costs, at a higher absolute dollar cost
No Webster Groves-specific homeowners-insurance premium figure distinct from Missouri's own statewide figures was found this pass -- Missouri insurance costs are rising statewide (a real projected 7% increase across 2026, following 9% in 2025), and Webster Groves' substantially above-average home values mean the real dollar cost runs higher in absolute terms than in most other Missouri Tier B markets.
