Index capital gains for inflation, Mr. President

Key Points
  • As Congress pivots to tax reform, Trump can take wealth creation into his own hands by issuing an executive order to index capital gains for inflation.
  • Removing taxation of inflationary capital gains is the fair thing to do for investors and it would spark a wave of prosperity.
  • Indexing capital gains for inflation this year would by 2025 create an additional 400,000 jobs, grow the U.S. capital stock by $1.1 trillion and boost GDP by roughly $500 billion, an economist said.

President Donald Trump's pledge to "Make America Great Again" requires nothing less than reigniting economic growth and prosperity. Wealth creation is essential. Yet as Congress pivots to tax reform — which is crucial to the wealth creation that will put the nation back on the prosperous path — the president can take matters into his own hands by issuing an executive order to index capital gains for inflation.

President Trump's absolutely best economic policy so far has been his relentless rampage against onerous, burdensome, costly, prosperity-killing regulations on business. And the taxation of inflationary capital gains fits right in there. It is an unfair and misguided policy that punishes risk and success. The president should use his executive authority — as he so often has to drain the swamp — to remove this prosperity-killing practice.

Consider this: You invest $1,000 and, after ten years, you sell that investment for $1,200. But if inflation averaged 2.5 percent in that period, the $1,200 you receive will be worth less in real terms than the $1,000 you invested. And yet, under current law, you will pay a tax on your $200 capital gain.

The results of this policy can be perverse. "As has been well documented," writes Alan Auerbach, University of California economist, "realized capital gains may be subject to tax rates that easily exceed 100 percent of real gains in the presence of inflation."

But it's the law. And not only would eliminating it be the fair thing to do for investors, it would spark a wave of prosperity.

Former Treasury economist Gary Robbins estimates that indexing capital gains for inflation this year would, by 2025, create an additional 400,000 jobs, grow the U.S. capital stock by $1.1 trillion and boost GDP by roughly $500 billion. That all translates to an additional $3,600 for the average household.

President Reagan ushered in two decades of prosperity with his tax and regulatory policies, including an audacious (and sorely needed) measure to index much of the federal tax code for inflation. That capital-gains indexation was not included in that measure has bedeviled economists who consider it bad policy to levy a tax on inflationary gains.

Congress has repeatedly toyed with legislation to index capital gains. In fact, a measure containing a fix to the problem landed on President Bill Clinton's desk in 1995 — only to be vetoed.

If President Trump wants to hear firsthand why capital-gains indexation is so important, he need only speak with his vice president. As a congressman a decade ago, Mike Pence introduced legislation with 88 co-sponsors to index capital gains for assets held for more than three years.

Capital-gains taxes totaled $134 billion last year. Approximately one-fourth of that revenue was, according to Gary Robbins, generated by taxing inflationary gains. That translates to a $34 billion tax on phantom income.

So opponents of capital-gains indexation say the associated revenue loss would be too great. But inasmuch as inflationary gains should not have been taxed in the first place, a revenue loss is a good thing. It represents the correction of a tax injustice.

But the second-order effects that Robbins documents should remove any reservations based on revenue loss. Without the federal tax on inflationary gains, asset prices will adjust until they reach a new, higher equilibrium. Shareholders and other investors will see their portfolios grow. And the federal government will collect billions of dollars in new tax revenue as taxpayers realize real capital gains.

Meanwhile, more investing and risk-taking will increase much-needed productivity, real worker wages, and overall economic growth. In fact, we betcha real revenues rise as well.

There is the question of whether the president has the legal authority to issue an executive order instructing the Treasury secretary to issue new regulations indexing the capital-gains cost basis for inflation. The matter comes down to whether the governing Internal Revenue Code section covering the definition of the word "cost" is sufficiently ambiguous to allow regulatory reinterpretation. Congress never specifically mandated that "cost" was to be determined in nominal terms, nor did it prohibit the use of real valuation.

When the George H.W. Bush administration looked into this 25 years ago, attorneys at the Justice and Treasury departments concluded that the president lacked legal authority. However, according to a landmark paper by Charles Cooper and Vincent Colatriano that appeared several years ago in the Harvard Journal of Law & Public Policy, "jurisprudential developments over the last two decades have confirmed ... that Treasury has regulatory authority to index capital gains for inflation."

Former Fed governor Wayne Angell correctly identifies the tax on phantom capital gains as "the worst aspect of the most damaging tax on capital." President Trump can solve this problem with the stroke of his pen and, in the process, promote economic growth and prosperity.
