Tax Policy Center’s Flawed $6.2 Trillion Revenue Loss from Trump Tax Plan

A crucial graph in the Wall Street Journal article, “Trump Fiscal Plain Roils the GOP,” relies on estimates from the Tax Policy Center. Unfortunately, the TPC provides only static estimates of revenue effects of House Republican or Trump tax plans.  That is, they assume lower marginal tax rates on families and firms have literally no effect at all on tax avoidance or long-term economic growth. 

The Wall Street Journal graph purports to project budget deficits over the next 10 years under Congressional Budget Office (CBO) baseline, the House Republican tax plan and the Trump tax plan.  This is quite misleading, because all three scenarios treat future federal spending as given, unchangeable.  Federal spending rose from 17.6% of GDP in 2001 to 19.1% by 2007, and is now 20.7% in 2015. The 2017 Budget projects spending to reach to 22.4% by 2021 and keep rising. 

The CBO August baseline projects federal spending to total $50.2 trillion from 2017 to 2026, so a mere 5% reduction in that growth would exceed $2.5 trillion.

Under President-elect Trump’s revised tax proposal, claims the Tax Policy Center, “revenues would fall by $6.2 billion over the first decade before accounting for interest costs and macroeconomic effects. Including those factors, the federal debt would rise by at least $7 trillion over the first decade.” 

Do not confuse these alleged “macroeconomic effects” with dynamic analysis used in Tax Foundation models and academic studies. The Tax Foundation estimates, for example, that the House Republican tax plan “would reduce federal revenue by $2.4 trillion over the first decades on a static basis,” but that figure shrinks to $191 billion once they properly account for improved investment incentives,  greater labor and entrepreneurial effort and therefore faster economic growth. 

By contrast, the Tax Policy Center presents only “macro feedback” estimates for the Trump plan. The TPC Keynesian model and Penn-Wharton models assume that revenue losses are 2.6% of GDP, the same as static estimates.  But interest rates are higher, adding to deficits and debt.

Know Your Libertarian History: The Great Tax Revolt of the 1970s

One of the great libertarian victories of the past few decades was the tax revolt of the late 1970s and early 1980s. The inflation of the 1970s caused higher property taxes and income tax bracket creep, which led to California’s Proposition 13, the Kemp-Roth tax cut bill, the election of Ronald Reagan in 1980, the 1981 tax cut, the deceleration of government spending, the further lowering of marginal rates in 1986—and a long period during which economic growth exceeded government growth.

This story isn’t told often in history books and popular media. Even with the boom in histories of modern conservatism, which in many instances focuses on the reaction to socialism and the welfare state, there is rarely a sense of the important arguments that free-market advocates were making. That’s why it’s important to have historians who understand economics and appreciate the value of limited government. One such historian is Brian Domitrovic, author of Econoclasts: The Rebels Who Sparked the Supply-Side Revolution and Restored American Prosperity.

In the latest issue of Cato Policy Report, the Cato Institute’s newsletter for Sponsors and friends, Domitrovic has a lead article titled “Tax Revolt! It’s Time to Learn from Past Success,” where he tells the story outlined above. If you get discouraged about the possibility of positive change, you should read it. Or read it if you just want to know more about the history of movements for limited government.
