Doyle noted the state has a history of tax credits that didn't work as intended.
"I'm not saying these won't work. We just don't know," he said.
The two new jobs credits would be capped at a total of $6 million a year for 16 years, for a maximum of $96 million in credits.
The bill does not cap the total amount of other tax exemptions available.
"I guess we're assuming here that folks paying less taxes creates a better business climate," said Delegate Marty Gearheart, R-Mercer, raising concerns about the amount of tax credits that would be available.
Skaff said the bill is based on similar programs that helped revitalize communities across the country, the closest being Homestead, Pa., a township south of Pittsburgh.
"It was just an awful area of town ... where nobody wanted to live," he said.
He said unlike past tax credits given to attract businesses to the state, companies participating in Project Launchpad would have to prove they had created good-paying full-time jobs with benefits to qualify for the tax relief.
"None of us are for just giving out tax credits without knowing if they create jobs," Skaff said, adding, "If you create jobs, we want to help you."
In 2013, a similar version of the bill (SB520) advanced from the Senate Economic Development Committee, but was never taken up in Senate Finance.
