The Solution to 1.2% Second Quarter GDP Growth Results: Top Ten Business and Individual Tax Reforms

August 1, 2016

After nearly a decade of rock-bottom interest rates, the Commerce Department announced that second quarter GDP grew by a dismal 1.2 percent. This is the third consecutive quarter of sub-par economic growth, much of this the result of low business investment and productivity.

Since it is obvious that low interest rates are no longer having any effect on spurring stronger growth, lawmakers should look to tax reform to revitalize the economy. In our recent book Options for Reforming America’s Tax Code, Tax Foundation economists measured the economic effects of 86 changes to the tax code, many of which would meaningfully growth the size of the economy and create more jobs.

The table below lists the top pro-growth business tax reforms and the top ten pro-growth individual tax reforms, along with our estimate of how much the policy would lift the long-term level of GDP, the number of jobs it would create, and the dynamic effect it would have on federal tax revenues. We’ve listed the option number in the book so that readers can learn more about each policy change.

Naturally, lawmakers will have to weigh the desired economic gains against the policy’s impact on the federal deficit, absent any cuts in federal spending. Some of these policies could generate a substantial amount of economic growth at a relatively small cost to the Treasury, while others may produce much less growth at a significantly greater cost.

For example, of the twenty policy changes listed below, the policy that delivers the largest boost to long-term GDP is Option #61, reducing the corporate tax rate to 25 percent while allowing businesses full expensing for new investments. This tax reform option would increase the level of GDP by 6.6 percent over ten years, at a dynamic loss in federal revenues of $1.2 trillion.

By contrast, the individual tax change that produces the most growth is Option #02, lowering marginal tax rates across the board by 20 percent. This option boosts long-term GDP by 2.1 percent, but at a dynamic cost to the Treasury of $3.4 trillion.

However, each policy change requires tradeoffs. While the corporate rate cut creates the most growth with a smaller revenue loss, it creates fewer jobs than the individual rate cut. Lawmakers will have to determine which is more important, growth, jobs, or federal revenues. Considering the latest economic news, generating economic growth should be priority number one, followed by jobs, then federal revenues.
