Estimating the Present Value of R&D Tax Benefits in the United States

Using a panel of confidential corporate tax returns, we provide the first direct estimates of the realized present value of corporate tax benefits from R&D credits and deductions in the United States. Realized tax benefits can deviate from statutory tax benefits because firms in loss status are typically unable to fully utilize credits and deductions to offset current-year taxes and instead must carry these attributes forward. We develop a novel procedure to track the intertemporal firm-level utilization of tax attributes generated by corporate R&D spending, and find that the present value of R&D tax benefits varies substantially with firms’ loss status, age, and size. Old and large firms typically use R&D tax benefits quickly, while young firms – especially those that are small – frequently operate in loss status and use tax attributes more slowly. From 2012–2016, the average firm generated $0.41 in statutory tax benefits per dollar of R&D investment, with a realized present value of $0.36. Young and small firms in a loss position realized only $0.23 per dollar, a 44% decrease relative to the statutory benchmark.
