If lower rates and a territorial system are the carrots, the House and Senate bills also include sticks—provisions intended to discourage tax-law arbitrage by large companies. One such measure, in both bills, would impose a global minimum tax of 10% on most companies. House and Senate details differ, but in essence, companies paying less than 10% tax on profits in foreign jurisdictions—dubbed “global intangible low-tax income,” or GILTI—would have to make up the difference to the IRS. That would narrow the advantage for firms operating in low-tax countries like Ireland, Luxembourg or various island tax havens.
The debate over tax reform is focusing on all the wrong things: the personal rates and the deduction for state and local taxes. What will truly matter for the economy is corporate tax reform, which will lead to a major increase in capital spending by companies. That in turn will raise productivity and real wages.These gains start small but will grow year after year as capital flows to corporate investment in the U.S. from the rest of the world and from other parts of the U.S. economy... Since GDP is projected to be $30 trillion in 2027, a $500 billion increase represents a gain of 1.7%, or just 0.17% per year over the decade... Cutting the corporate rate to 20% would raise retained earnings by about $2 trillion over 10 years... The lower tax rate will also induce foreign companies to shift some of their production to America. And capital within the U.S. will move from low-productivity uses in agriculture and housing to corporate investments.. It is troubling that America’s ratio of debt to GDP has more than doubled in the past 10 years and is projected to increase from 77% today to 91% in a decade.. An extra $1.5 trillion of debt will raise that ratio to 96%. But I believe the advantages of the corporate tax reform outweigh the adverse effects of the relatively small debt increase... The debt-to-GDP ratio, which was 35% as recently as 2007
