I examine whether tax return information is useful to equity investors. I do so indirectly, by exploiting unique features of the syndicated loan market, as evidence shows that lenders obtain tax returns from borrowers and that lenders’ private information is transmitted to equity markets when institutional investors are part of a loan syndicate. I find significant increases in tax expense valuation and decreases in tax-related market anomalies following the issuance of institutional syndicated loans, suggesting that equity investors find information about firm performance in tax returns that is useful for their trading decisions. I also find evidence suggesting that institutional investors may determine their loan syndicate participation in part based on the value of tax return information. This study extends prior research and informs policy debates over public disclosure of corporate tax return information by providing evidence to support that tax returns can be useful to investor decision making.

This study provides the first large‐sample evidence on the economic tax effects of special purpose entities (SPEs). These increasingly common organizational structures facilitate corporate tax savings by enabling sponsor firms to increase tax‐advantaged activities and/or enhance their tax efficiency (i.e., relative tax savings of a given activity). Using path analysis, we find that SPEs facilitate greater tax avoidance such that an economically large amount of cash tax savings from research and development (R&D), depreciable assets, net operating loss carryforwards, intangible assets, foreign operations, and tax havens occur in conjunction with SPE use. We estimate that SPEs help generate over $330 billion of incremental cash tax savings, or roughly 6 percent of total U.S. federal corporate income tax collections during the sample period. Interaction analyses reveal that SPEs enhance the tax efficiency of intangibles and R&D by 61.5 percent to 87.5 percent. Overall, these findings provide economic insight into complex organizational structures supporting corporate tax avoidance.
