Taxes are one of life's few constants. They are also one of the main sources of revenue for the state of Wisconsin, paying for many of the state's programs, services, and infrastructure projects. Wisconsin has laws imposing a number of different taxes, including consumer taxes, a state personal income tax, and estate taxes. For example, Wisconsin law requires individuals, estates, and trusts to pay roughly between four to seven percent of their net income to the state in the form of a personal income tax. In addition, Wisconsin places consumer taxes on the sale of products like cigarettes and alcohol. Click on one of the links below to learn more about Wisconsin tax laws.
