Florida Gov. Ron DeSantis plans to go ahead with more than a half-billion dollars in tax refunds for the state’s largest corporations — even as the state economy crashes amid the spreading coronavirus pandemic. The Republican-controlled Florida Legislature committed to the corporate tax refunds — which will total $543 million — two years ago, long before lawmakers had any idea how big they would be. The state hasn’t paid them out yet and doesn’t have to until May 1. But Florida is suddenly bracing for a potentially unprecedented drop in sales tax collections as commercial activity shuts down, along with surging demand for state government services as workers across the state lose their jobs en masse. So some activists want DeSantis to use his emergency power as governor to stop the refunds.
