About Wisconsin's rates

Planning note
Wisconsin's top rate (7.65%) is meaningfully higher than neighboring Minnesota's (9.85%) but applies much later. For middle-income earners, Wisconsin's effective rate tends to be lower. Cross-border commuters to MN or IL should model both states' taxes on their full income.
