Critics and supporters of Donald Trump’s deal that kept Carrier Corp. from exporting hundreds of jobs from Indiana to Mexico have spent much of the past week arguing about how many jobs the deal actually saved.

But what the public will likely never know is how much the deal helps the air conditioning company’s annual state tax bill. It's information that's typically not released but can reveal whether a tax incentive has the potential to bring a business' state tax burden down to zero.

Last week, President-elect Trump and Vice President-elect Mike Pence, who is still serving as governor of Indiana, announced a deal with Carrier that they say will keep 1,100 jobs in the state in exchange for $7 million in tax breaks over a decade. Since the announcement, unions have refuted the jobs number and said it’s closer to 800 since Carrier still plans to export 500 jobs to Mexico.
