After two fizzled efforts to obtain tax exemptions for a soccer-specific stadium, Minnesota United was successful when Gov. Mark Dayton signed the tax bill into law Tuesday night.

The tax bill, which was passed in the Legislature’s special session, includes property and sales tax breaks to help United build a privately financed, $150 million stadium in St. Paul. Property tax forgiveness has been included in every pro and college stadium project in Minnesota since 1998.

In a statement late Tuesday night, United owner Bill McGuire thanked the governor and Legislature for passing the bill “vital to our stadium goals.

“We look forward to continuing our efforts to build what we believe will be a world-class, soccer-specific stadium that will serve our team, our fans and our community, and will make everyone in Minnesota proud.”

The Major League Soccer expansion franchise, which began renting TCF Bank Stadium as a temporary home this spring, had sought those tax breaks when the club introduced plans to build a stadium in Minneapolis in 2015.

But after failing to secure support at the state Capitol and in Minneapolis that year, the club moved the stadium’s site to the St. Paul corner of Snelling Avenue and Interstate 94 in 2016.

Then last year, the club’s tax exemptions were caught up in a bill ultimately scuttled because of an unrelated $100 million wording error tied to public funding for the Vikings stadium.

This third try was successful. McGuire said Saturday that 95 percent of the stadium’s designs are done and construction could begin in June or early July. The target opening is March 2019, in time for the club’s third season in MLS. In the meantime, the Loons have a two-year agreement to play at the University of Minnesota’s football stadium.

McGuire said construction will start on the stadium’s southern edge and work its way north. This plan will provide added time to work on the complicating leases for existing businesses occupying shops on the site’s northern edge.
