A financial transaction tax would help ensure Wall Street works for Main Street

What this report finds: A well-designed financial transaction tax (FTT)—a small levy placed on the sale of stocks, bonds, derivatives, and other investments—would be an efficient and progressive way to generate tax revenues. Gross revenues from a well-designed FTT would likely range from $110 billion to $403 billion. And net revenues (including offsets from reduced income, payroll and capital gains taxes, and increased borrowing costs) would likely be substantially higher than some other recent estimates indicate. This is mainly because other estimates’ assumptions about the volume of financial transactions an FTT would crowd out are too high, and because an FTT is likely to redistribute rather than reduce overall incomes. Regardless of the level of revenues raised, an FTT would be a win-win for the U.S. economy. Higher revenues would result in more funds for social insurance programs and much-needed public investments. Lower revenues would be the result of the FTT crowding out financial transactions of little value to the U.S. economy. This would boost Americans’ incomes through lowering fees on financial services, such as the management of 401(k)s and other accounts.
