Chicago's 10.25% includes the 6.25% state rate, 1.25% Cook County tax, 1.25% Chicago city tax, plus additional local taxes. Downstate cities typically have lower combined rates (around 6.25-8%). This reflects Chicago's higher service demands and transit infrastructure funding through the Regional Transportation Authority tax.
