Bill Overview
Analyzed Economic Effects
3 provisions identified: 0 benefits, 1 costs, 2 mixed.
Corporations lose partial-year business surcharge adjustment
Corporations starting or stopping business in Wisconsin during a tax year no longer get a days-in-business surcharge adjustment. The economic development surcharge uses the general formula instead. It is 3% of a corporation’s gross tax liability, or 0.2% of a tax-option corporation’s net income. The law states the limit as “up to a maximum of $9,800, or $25, whichever is greater.” Ending the adjustment can raise the surcharge for affected corporations.
Local development districts change property counted
Wisconsin changes which property counts for tax increment financing in local development districts. The definition includes real property in the district but excludes personal property. The law does not state a direct change in household taxes or benefits.
Wisconsin reorders certain income tax payments
Wisconsin adds certain withholding and deposits toward the end of its income tax calculation order. These include withholding for nonresident owners of pass-through businesses and deposits by nonresident entertainers or entertainment corporations. The rules cover individual, trust, estate, and corporate income tax calculations. The law does not state a specific increase or decrease in tax owed.
