A familiar name has cropped up on California's new list of deadbeat taxpayers: David Hayden, who owes the state. He owes $2.7 million in state taxes, making him one of the Bay Area's top tax debtors. Could this be the same Hayden whose up-and-down startup career has put him in massive debt to his bankers? Seems likely, given this Hayden's Mill Valley address. [California Franchise Tax Board]
