It's a deal many out-of-state companies have found too good to refuse: Move to Florida and get millions of dollars in tax incentives from Tallahassee.

But many fail to deliver the jobs they promised to create, and lawmakers want to be sure those companies and the governor are held accountable.

It's a simple pledge Rick Scott made the centerpiece of his two campaigns for governor, and during his time in office, the jobs have come – 600,000 of them, many the result of the national economic recovery.

Governor Scott’s taking credit, too, pointing to what he says is Florida’s improved business climate -- a climate that under his watch has included $266 million worth of tax incentives, all of it doled out to companies in return for jobs.

“The way I think about this is, if we want more jobs in Florida, basically, we've got to make sure Florida companies do well,” Scott said.

But now, some lawmakers want to know just how well those companies are doing and if they've delivered on their promises.

A new bill would mandate an independent annual review of the corporate tax incentives.

For Governor Scott, job creation has become a near obsession, a relentless drive to move the numbers.

The problem: when it comes to tax incentives, those numbers have been moving at a snail's pace. Only five percent of the jobs promised have actually materialized.

Dan Krassner with the watchdog group Integrity Florida has been pushing for years to get details about the incentives.

But all too often Enterprise Florida, the panel chaired by Governor Scott that hands out the money, has said "no."

“These tax incentives take years to fully develop,” said Krassner. “There hasn't been the greatest track record with the Enterprise Florida program. Often times, companies promise a larger number of jobs than they actually deliver.”

The question is if those companies are being forced to give back all the taxpayer money they've taken - and if they aren't, then why not.

So far, the answers have been slow in coming, but that could be about to change.

The governor's office says companies have 10 years to make good on their job promises, but critics say that's simply too long.
