President Obama will address both houses of Congress and the American people Tuesday to discuss the State of the Union.

The address is expected to touch on tax reform, including new tax credits for families with two working parents; bigger, simpler tax credits for child care, college and retirement; and a plan to pay for it all with higher taxes on what the administration calls the “wealthiest.” That includes the wealthiest people, with tax hikes on capital gains and inheritances, but also the wealthiest financial institutions: Those with at least $50 billion in assets.

More specifically, it’s a tax on bank debt. Anat Admati, a Stanford University professor of economics and finance, says this could help push back perverse incentives in the current tax code, which encourage banks to do business with borrowed money. But it’s an approach that has been proposed before, and as recently as 2010 when it was called the Financial Crisis Responsibility Fee. It failed back then and with Republicans in charge of Congress, it doesn’t have a chance, says Joel Slemrod, an economics professor and director of the Office of Tax Policy Research at the University of Michigan.
