A group of Democratic lawmakers is seeking a steep increase to Delaware’s corporate franchise tax, in a bill seemingly at odds with a plan championed by Gov. John Carney in his first budget proposal.

The bill, introduced Tuesday evening in the House of Representatives, calls for a 33 percent hike in the annual amount Delaware’s biggest businesses pay to incorporate in the state. Under the legislation, those corporations would face a tax of $240,000, compared to the current maximum rate of $180,000.
