While Citizens for Tax Justice has been taking a deep dive into offshore-tax sheltering and why the corporate tax is indispensable, some friends and allies have put out a series of reports over the past week on the economic impact (or not) of corporate taxes, the enduring dominance of corporate lobbyists and the need to revisit our fiscal policy debate in light of new evidence. Below we highlight the most crucial findings of these must-read reports.

Economic Policy Institute: Corporate Tax Rates and Economic Growth Since 1947

The Economic Policy Institute’s (EPI) most recent report on corporate taxes by Thomas Hungerford (author of that high profile Congressional Research Service report showing income tax cuts create more inequality than jobs) debunks the pervasive myth that the US’s corporate tax rate is harmful to the economy. For one, Hungerford notes that although the US has a high on-paper marginal rate compared to other countries, its effective corporate tax rate is just about average compared to other rich, developed countries. In addition, Hungerford notes that despite all the claims about corporate taxes preventing growth, corporate profits in the US are actually at an historic high.

Backing up these points (for our stats-minded readers), Hungerford performed a multivariate analysis comparing GDP growth and corporate tax rates and found that corporate tax rates (including the effective and statutory rate) have no correlation with economic growth. This conclusion even held true when controlling for other economic factors and for a lag effect on growth. In other words, the idea that cutting corporate taxes will increase growth in the US has no basis in the historic evidence.

Public Citizen: Lax Taxes

In it’s report Lax Taxes, Public Citizen makes case studies of the lobbying around three pieces of progressive tax legislation to demonstrate the disproportionate firepower of corporate lobbyists versus public interest groups. Appallingly (though not surprisingly), Public Citizen found that 86 percent of the lobbyists who reported lobbying on the Stop Tax Haven Abuse Act (STHA), the CUT Loopholes Act, and the Wall Street Trading and Speculators Tax Act represented corporate clients. Looking at the STHA specifically, the group found that for every one pro-tax reform lobbyist there were 20 lobbyists representing industry interests.

Perhaps even more disturbing, Public Citizen found that of those lobbyists with previous government experience working on these bills, 96 percent of them represented corporate clients rather than ordinary Americans. This dynamic not only means that industry advocates have deeper connections to Congress, but also that current lawmakers and Congressional staffers have an incentive to appease corporate interests if they themselves want to get a job a lobbying gig after they leave Capitol Hill.

Further, Public Citizen also notes that groups opposing these pieces of legislation donated about four times as much in campaign contributions to lawmakers that those supporting them, which may explain why these common sense reforms have failed to move despite overwhelming public support for closing corporate tax loopholes.

Center for American Progress: It’s Time to Hit the Reset Button on the Fiscal Debate

The prevailing ethos in Washington over the past few years is that budget deficits are out of control and that austerity measures must be taken in order to prevent economic catastrophe. A new report from the Center for American Progress (CAP) shows that this conventional wisdom is all wrong given recent policy actions and mounting evidence.

Most importantly, CAP points out in their report that Congress and the President have already enacted $2.5 trillion worth of deficit reduction (three-quarters of which took the form of spending cuts) since the start of fiscal year 2011. While many lawmakers and pundits are still warning that without additional and immediate deficit reduction the debt will spin out of control, the reality is that the current level of deficit reduction is already enough to stabilize the debt as a percentage of GDP through 2023.

CAP also notes that a research paper often cited by debt alarmists to argue for immediate deficit reduction has been pretty thoroughly debunked. Specifically, the claim by Carmen Reinhart and Kenneth Rogoff that a debt level over 90 percent of GDP jeopardizes economic growth is based on a calculation error (oops!) and does not take into account that causation can work both ways. 

One final important point in CAP’s report is growing evidence from Europe that austerity has actually made the economic situation there worse rather than better. Why? Budget cuts create a downward spiral by increasing unemployment and reducing consumption, which then results in even lower revenues and higher deficits. Some proponents of austerity have tried to counter this evidence by arguing that it’s austerity in the form of tax increases that is driving lower growth, but this logic has also been debunked.
