Prior to the 2017 Tax Cuts and Jobs Act (TCJA), the U.S. corporate tax rate was the highest among developed economies, driving companies overseas in search of more competitive tax environments. TCJA helped level the playing field for American businesses by setting the U.S. corporate rate at 21%. By creating a more globally competitive tax system for American companies, tax reform disincentivized companies from relocating their headquarters abroad while encouraging businesses to invest more at home.
