We estimate the budgetary and economic effects over the 10-year budget window (2021 - 2030) of Senator Bernie Sanders proposal for a graduated wealth tax starting at 1 percent tax on married couples’ net worth above $32 million, 2 percent tax on net worth from $50 to $250 million, 3 percent tax from $250 to $500 million, 4 percent tax from $500 million to $1 billion, 5 percent tax from $1 to $2.5 billion, 6 percent tax from $2.5 to $5 billion, 7 percent from $5 to $10 billion, and 8 percent tax on wealth over $10 billion. For unmarried individuals, the net worth cutoffs for these brackets are halved.
