Governor Scott Walker signaled Monday the state would start collecting sales taxes for internet purchases, but offset any new money with cuts to other taxes by the same amount. The U.S. Supreme Court last week ruled states could collect taxes for online sales far more broadly than had been allowed under a 1992 decision. Wisconsin could take in $123 million to $187 million a year from online sales taxes. Wisconsin’s sales tax is 5%. Milwaukee County and 65 other counties charge a 0.5% sales tax.
