Abstract:
We study changes in tax positions for U.S. C corporations following passage of the 2017 tax legislation commonly known as the Tax Cuts and Jobs Act (TCJA). While existing research has focused primarily on publicly traded companies, data limitations have prevented more holistic analyses of the corporate sector. Using a representative sample of U.S. corporate tax returns, we highlight how trends in effective tax rates (ETRs) and exposure to the legislation's main provisions varied for public, private, multinational, domestic, and large versus small firms. We document several novel facts, including that ETRs increased on average for privately held, domestic firms and for firms in the bottom 90% of the firm sales distribution after TCJA. In contrast, public, multinational, and large firms saw substantial ETR cuts on average. We find that firms' pre-TCJA exposure to changes in the corporate tax rate and treatment of net operating losses have the strongest correlation with post-TCJA ETR changes. Overall, the analysis underscores the divergent impacts of TCJA on different firm types and illuminates the economic scope and relative significance of TCJA's myriad provisions.
