It would take at least 25 years for Wisconsin taxpayers to break even on Gov. Scott Walker's incentives to lure Taiwanese electronics giant Foxconn to the state, according to a fiscal analysis released this week.

Walker's bill would exempt construction materials from the state and local sales tax and hand the company up to $2.85 billion in tax credits based on the number on the number of jobs generated.

It also would exempt the company from a host of environmental regulations and borrow $252 million to rebuild Interstate 94 near the plant site.

The analysis has placed the deal that President Donald Trump called 'incredible' in jeopardy.

The leader of the Wisconsin Senate said Wednesday he doesn't know if he has the votes to pass the incentives package, raising doubts about whether legislators will be able to meet a deadline for finalizing the deal.

Senate Majority Leader Scott Fitzgerald expressed concerns about some specifics of the deal with the Taiwanese electronics giant, which could decide to go elsewhere for its first U.S. factory if the $3 billion package isn't approved by Sept. 30.

The nonpartisan Legislative Fiscal Bureau's released an analysis of the bill on Tuesday that said the cost of the tax credits being offered would exceed potential increased tax revenues by $1.04 billion at the end of fiscal year 2032-33.

After that year, payments to Foxconn would end and increased tax collections would ring in at about $115 million annually. At that rate, the break-even point would come during the 2042-43 fiscal year.

The break-even point could come even later, though.

Foxconn hasn't formally picked a site yet but the company is eyeing an area in Wisconsin just across the Illinois border.

If 10 percent of the jobs associated with the plant go to Illinois residents instead, the break-even point would be pushed back to 2044-45, the analysis found.

If 40 percent to 50 percent of the jobs go to out-of-state residents, the break-even point would be pushed well past 2044-45, the analysis said.

Foxconn hopes to open the plant with 3,000 workers. A promised initial investment of $10 billion could yield another 10,000 jobs, Trump and Walker have stressed.

'The construction of this facility represents the return of LCD electronics and electronics manufacturing to the United States, the country that we love. That's where we want our jobs,' Trump declared from the White House's East Room on July 26.

With Walker and House Speaker Paul Ryan, a Wisconsinite who stands to benefit from the deal, by his side, Trump proclaimed: 'To make such an incredible investment, Chairman Gou put his faith and confidence in the future of the American economy.

'In other words, if I didn't get elected, he definitely would not be spending $10 billion.'

The president claimed last week that Foxconn founder Terry Gou told him in private that he could triple the agreed upon amount and go up to $30 billion, if all goes well.

Critics have questioned whether the company really intends to add more employees, though.

If the facility employs closer to 3,000 people, the tax benefits from the project would decline from $115 million to $27 million annually and the break-even point would come well beyond 2044-45.

What's more, borrowing for the interstate rebuild would leave the state on the hook for $408.3 million in interest and the sales tax exemption would cost the state $139 million.

If Foxconn builds the plant in Kenosha County, the local sales tax exemption would cost that county about $13.9 million.

Neighboring Racine County doesn't have a county sales tax, but the county is part of the stadium district that collects a 0.1 percent sales tax to support Miller Park, the Milwaukee Brewers' home. The local exemption would cost the district about $2.78 million in revenue.

The Legislative Fiscal Bureau's also noted that Foxconn's presence in the state could have substantial benefits.

Every public dollar would generate $6.70 from Foxconn, the analysis said, and the plant would provide more job opportunities as well as a new manufacturing sector in Wisconsin. Kenosha County and the stadium district could benefit from local sales tax revenue connected to developments related to the plant.

Citing the private-public investment ratio, Walker spokesman Tom Evenson called the Foxconn plant a 'once-in-a-lifetime opportunity.'

The Republican leader of the Wisconsin senate said he wants to know more about how bonding for interstate reconstruction near the plant's site will affect a $1 billion shortfall in the state's transportation fund, however.

He also expressed concern about the fiscal analysis.

Despite Fitzgerald's concerns, Assembly Republicans planned to take the first votes on the package next week, with a committee vote set for Tuesday and a full floor session scheduled for Aug. 17. Assembly Speaker Robin Vos tweeted he wants the Legislature to pass the plan by Labor Day.

Fitzgerald accused Vos of drafting amendments to the plan without consulting the Senate, further complicating matters. He said he plans to send the bill to the Legislature's budget-writing committee but wants the panel to finish work on the state budget before it takes up the Foxconn bill.

Rep. Gordon Hintz, a Democratic member of the Legislature's finance committee, predicted the incentives bill would create long-term problems for every state budget for the next 15 years, ultimately resulting in cuts to important state programs.
