President Trump wants to cut the tax rate for all American businesses to 15 percent, and damn the deficit. If you believe him, any damage from higher deficits will be minor compared to the benefits for US competitiveness, economic efficiency, and tax fairness. The truth is, those claims are nonsense; and the real agenda here is the 2018 and 2020 elections. Without substantial new stimulus, the GOP will likely face voters in 2018 with a very weak economy – and tax cuts, especially for business, are the only form of stimulus most Republicans will tolerate. Moreover, if everything falls into place, just right, deep tax cuts for businesses could spur enough additional capital spending to help Trump survive the 2020 election.
Let’s review the economic case for major tax relief for American companies. It’s undeniable that the current corporate tax is inefficient – but does it actually make U.S. businesses less competitive? The truth fact is, there’s no evidence of any such effects. In fact, the post-tax returns on business investments are higher in the United States than in any advanced country except Australia, and the productivity of U.S. businesses is also higher here than in any advanced country except Norway and Luxembourg.
The critics are right that the 35 percent marginal tax rate on corporate profits is higher than in most countries. But as the data on comparative post-tax returns suggest, that marginal tax rate has less impact on investment and jobs than the “effective tax rate,” which is the actual percentage of net profits that businesses pay. On that score, the GAO reports that U.S. businesses pay an average effective tax rate of just 14 percent, which tells us that U.S. businesses get to use special provisions that protect 60 percent of their profits from tax (14 percent = 40 percent of 35 percent).
Tax experts are certainly correct that a corporate tax plan that closed special provisions and used the additional revenues to lower the 35 percent tax rate would make the overall economy a little more efficient. But lowering the rate alone while leaving most of those provisions in place would have almost no impact on the economy’s efficiency – and the political point of Trump’s plan depends on not paying to lower the tax rate.
Finally, would a 15 percent tax rate on hundreds of billions of dollars in business profits help most Americans, as the White House insists, since 52 percent of us own stock in U.S. corporations directly or through mutual funds? The data show that most shareholders would gain very little, because with 91 percent of all U.S. stock held by the top 10 percent, most shareholders own very little stock.
Moreover, the proposed 15 percent tax rate would cover not only public corporations but also all privately-held businesses whose profits are currently taxed at the personal tax rate of their owners. So, Trump’s plan would slash taxes not only for public corporations from Goldman Sachs to McDonald’s, but also for every partnership of doctors or lawyers, every hedge fund and private equity fund, and every huge family business from Koch Industries and Bechtel, to the Trump Organization..
There is no doubt that the President’s tax plan would provide enormous windfalls for the richest people in the country. Beyond that, it may or may not sustain growth through the next two elections, since even the best conservative economists commonly overstate the benefits of cutting tax rates. But the truth is, there aren’t many other options that a Republican Congress would accept.
