rate fell from 50 to 28, and both sides viewed the development with favor. Bipartisanship has been good
for tax reform. And tax reform, as we shall see, has been good for America.
Economists who have studied the effects of taxes over time have developed a consensus: lower
marginal tax rates and a broader base increase rates of economic growth and well-being. I have been in
this room often over the past 20 years, and have witnessed head-nodding that broadening the base and
lowering the rates, as President Trump’s plan aims to do, is a recipe for better tax policy. I can’t recall
ever seeing anyone in this room argue that narrowing the base and raising rates was a recipe for growth.
For years, TPC analyzed tax bills without providing dynamic scoring, but now provides a dynamic score,
but with zero effect. I suppose that’s some progress.
This consensus has spread around the world as well, and has been especially visible in the corporate tax
space. In 1989, the year the Berlin Wall fell, the average statutory corporate tax rate imposed by central
and sub central governments in the OECD was 43 percent. In 1989, the comparable rate in the U.S. was
about 39 percent. In the time since the Wall fell, the OECD average corporate tax rate has trended
downwards to its current 24 percent, about half of its 1989 level. The U.S. corporate tax rate, however,
is still stuck in the same place it was when the Wall crumbled, almost 20 years ago. We’ve seen the
results of that stasis, which has essentially incentivized American firms to offshore and kept foreign
investment away.
There is now a broad consensus in this country, on both sides of the aisle, that it is time to, shall we say,
“Tear down this rate.” Even President Barack Obama proposed lowering the Federal corporate rate to
28 percent. My guess is that President Obama did not make that proposal because he thought it would
have no effect. This bipartisan consensus within the United States echoes what policymakers around
the world have learned. In France, a country not exactly known for its long-standing devotion to supply-
side economics, President Emmanuel Macron has proposed cutting the corporate tax rate to 25 percent.
And France’s current corporate rate of 33 percent is already lower than ours. France joins such
countries as Denmark, Sweden, and Greece – a country that recently elected an avowedly socialist
government named the Coalition of the Radical Left or SYRIZA in Greek -- in having lower corporate tax
rates than our own. Let me repeat that: even the Coalition of the Radical Left in Greece, a country
under deep austerity measures, understands the bucket leaks.
Against this backdrop, let’s look at President Trump’s Unified Framework for Tax Reform. First, the
framework entails reforms to both the individual income tax system and the corporate tax system.
On the individual side, President Trump’s framework lowers the numbers of brackets to four rates: one
of 0, one a 12 percent, another at 25, one at 35, and leaves the door open for an additional fifth higher
marginal tax rate to ensure that the wealthy do not pay a lower share of taxes than they pay today. And
don’t forget more people are eligible for the zero rate under this plan.
President Trump’s plan retains incentives for home mortgage interest and charitable contributions, but
otherwise eliminates itemized deductions in favor of a doubling of the standard deduction. In pursuit of
simplification, the Unified Framework repeals personal exemptions, and it enhances the Child Tax Credit
by increasing its size and raising the income level at which it phases out, a reform that also eliminates
the marriage penalty. Those who care for other dependents, like the elderly, will receive a new $500
non-refundable credit. The Alternative Minimum Tax and the Death Tax will both be eliminated. The
idea is to simplify the system, end wasteful tax breaks, and eliminate loopholes. It is a simpler, fairer
system that increases the base and lowers rates.
