The Impact of Section 4960 Excise Tax on Nonprofit Executive Compensation and Turnover

Abstract

We examine the impact of Internal Revenue Service (IRS) Code Section 4960 of the Tax Cuts and Jobs Act of 2017 on nonprofit organizations (NPOs). This section imposes a 21% excise tax on nonprofit employee compensation exceeding $1 million per covered individual. As this is an exogenous shock imposing a cost on NPOs with highly paid employees, it leads us to examine whether those employees share the newly added cost via a reduction in their compensation. Using a difference‐in‐differences analysis on data from IRS Form 990 filings for nearly 40,000 nonprofit employee‐year observations from 2015 to 2010, we find that the level of compensation, on average, increases for treated executives in the post–Section 4960 period, but at a slower rate than that of the control group of executives. These results are consistent with highly paid employees being reluctant, on average, to take a pay cut, but being more willing to accept a reduction in their rate of pay growth. Our results are robust to alternative treatment specifications and control samples, such as employees who earn more than $1 million but are not covered under Section 4960 and medical professionals who are specifically exempt from Section 4960. We also find that compensation decreases are more likely for treated employees post–Section 4960 and that replacements for treated CEOs take an even steeper pay cut post–Section 4960. Additionally, we observe increased turnover for treated CEOs post–Section 4960, consistent with Section 4960 leading to conflicts between treated CEOs and their boards regarding the excise tax and who should bear its cost.
