Online sales tax revenue presents opportunity for permanent, comprehensive tax reform in Wisconsin

The Badger Institute and the Tax Foundation provide ideas for using revenue to address structural issues with the state's tax code 

Washington, D.C. (August 2, 2018) — Wisconsin is poised to collect an estimated $120 million in additional annual online sales tax revenue following the U.S. Supreme Court's recent South Dakota v. Wayfair ruling. In a joint policy brief released today, the Tax Foundation and the Badger Institute urge Wisconsin lawmakers to use this revenue flexibility to fix structural issues with the state's tax code. 

Given how poorly the state's individual and corporate tax structure ranks on the Tax Foundation's State Business Tax Climate Index, this revenue gives lawmakers ample room to make the tax code more fair and efficient. 

“Meaningful structural changes to the state's individual income tax, corporate income tax, and other parts of its tax code have the potential to make the state more attractive to businesses and families while improving the state's competitiveness among its neighbors and as a key player in the national economy," the report's authors write.  

Wisconsin's 2018 State Business Tax Climate Index rankings:

Overall Rank: #38
Corporate Taxes: #29
Individual Taxes: #43
Sales Taxes: #7
Property Taxes: #26
Unemployment Insurance Taxes: #40

Note: This policy brief precedes a larger joint Tax Foundation & Badger Institute report, to be published at the end of 2018, outlining tax reform options for Wisconsin policymakers to consider. These proposals will be designed to help set the state on a path to a stronger fiscal future.
