Analysis: Wisconsin Could Get $120 Million in Internet Taxes

The U.S. Supreme Court last month upheld South Dakota's plan to collect online sales taxes, clearing the way for other states.

A Legislative Fiscal Bureau analysis released Monday found if Wisconsin legislators made regulatory changes in time to start collection by Oct. 1, the state would take in $90 million by mid-2019 and $120 million the following year.

State law requires an equal cut in income taxes if federal law requires collecting online sales taxes. It's unclear if the court decision technically is a change in federal law, but if Wisconsin implemented collection under 2017 rates taxpayers would save an average $52.
