Relating to: authorizing counties and municipalities to impose local income taxes on high-income taxpayers and making an appropriation. (FE)

AB 1028 authorizes Wisconsin counties and municipalities to impose a local income tax on the portion of a resident's Wisconsin taxable income exceeding $1 million for single filers, $500,000 for separately filing married individuals, or $1 million for jointly filing married couples. Localities must adopt the tax via a referendum and apply it only to taxpayers who reside, own property, or work in the jurisdiction for at least 30 days annually. The state Department of Revenue would administer the tax, with 1.75% of collected revenue funding administrative costs.
