On June 22, Delaware Gov. Jack Markell (D) signed S.B. 40 into law, increasing the tax credits available to companies that create jobs in Delaware in general, but added extra incentives for manufacturers of clean energy systems. The new law, Delaware's Blue Collar Job Credit program, allows an eligible business that hired five or more workers and invested at least $200,000 in a qualified facility could take a $400 credit against the corporate or personal income tax for each qualifying job and each $100,000 increment of qualifying investment. For clean technology businesses (producing anything from fuel cells or solar, wind, or geothermal power), the credit rises to $750 and makes that company eligible for a lower gross receipts tax rate.
