#特朗普税改 Trump's tax reform mainly refers to the Tax Cuts and Jobs Act passed in 2017. Key points include: significantly reducing the corporate tax rate from 35% to 21% to stimulate investment and economic growth; lowering personal income tax rates and simplifying the tax bracket structure, although some tax cuts have expiration dates; increasing the standard deduction while eliminating or limiting several personal deductions; introducing a one-time low tax rate for repatriated overseas profits for international companies to encourage capital repatriation to the U.S. The overall goal is to reduce the tax burden, promote business expansion and consumer spending, but it has also sparked controversy over the widening fiscal deficit, with significant differences in impact across various income levels in the U.S.
