The Tax on Wall Street Speculation Act would impose a new federal tax on financial trading transactions, with rates ranging from 0.005 percent to 0.5 percent depending on the type of security being traded. The tax would apply to stocks, bonds, derivatives, partnerships, and digital assets when traded on U.S. exchanges or when either the buyer or seller is a U.S. person. The legislation exempts initial stock offerings and very short-term debt instruments from the tax. Trading facilities, brokers, and individual traders would be responsible for paying the tax depending on the transaction type. The bill would take effect on January 1, 2024, and includes a provision allowing eligible individuals earning below $50,000 annually (or $75,000 for joint filers) to claim a tax credit for financial transaction taxes they paid, though full-time students and certain other taxpayers would be excluded from this credit. According to the bill's stated purpose, revenue from this tax would be used to invest in families, communities, infrastructure, environmental protection, and financial security while also helping reduce market volatility.
