Evaluating TCJA’s Impact: Did the 2017 Tax Cuts Boost Business Investment?

The Tax Cut and Jobs Act (TCJA) of 2017 was heralded as a transformative policy extensively aimed at rejuvenating business investment in the United States. By significantly reducing corporate tax rates from 35% to 21%, alongside other substantial benefits, the TCJA aimed to render the U.S. an appealing hub for business investments. Non-corporate businesses also saw their top tax rates reduced from 37% to 29.6%. Beyond these cuts, the legislation allowed businesses to temporarily deduct the entire cost of certain investments upfront, eliminating the need for depreciation over time. With these sweeping changes, the U.S. administration envisaged a robust surge in business investments, thus propelling broader economic growth. However, did the TCJA achieve this ambitious aim?

The Intentions Behind TCJA

The primary objective of the TCJA was to stimulate business investment, aiming to lower the cost of capital significantly. By reducing the corporate tax rate by 14 percentage points and offering similar benefits to non-corporate businesses, the Act sought to make investment in the United States more appealing. Additionally, allowing businesses to temporarily deduct the entire cost of certain investments immediately instead of depreciating these costs over years was intended as a major incentive. Advocates for the TCJA argue that these measures were successful, citing research that points to an 8 to 14% increase in real corporate investments in equipment and structures. Even though these investments only constitute a fraction of total investment, which also includes investments by non-corporate businesses and intellectual property (IP) investments, backers of the TCJA maintain that the policy has had a positive impact.

However, the boost in corporate investment must be scrutinized in the context of total investment. Evaluating the overall effect on aggregate investment becomes essential to comprehensively determine the Act’s implications for the U.S. economy. The multitude of prevailing opinions and interpretations about the efficacy of the TCJA necessitates a deeper dive into various facets of business investment trends following the enactment of this legislation, beginning with aggregate investment trends. Did the TCJA actually translate into a meaningful surge in investment across the board? Let’s delve into the data.

Analyzing Aggregate Investment Trends

Despite reports indicating an uptick in corporate investments in equipment and structures, the broader impact on aggregate investment appears to be more limited. The TCJA succeeded in reducing the capital cost for investments in these sectors, yet the notable increase in the proportion of real GDP allocated to equipment investment was rather marginal, climbing from 5.9% in the 2015-16 period to just over 6.0% in 2018-19. Similarly, investments in structures remained relatively stable, maintaining a consistent share of GDP at 3.1% over these years. These figures suggest that while certain sectors did benefit from the tax cuts, the overall increase in investment was not as pronounced as anticipated by policymakers and economists.

The onset of the COVID-19 pandemic in 2019 unquestionably complicated the analysis of the TCJA’s long-term effects. Disruptions in economic activities, changes in business priorities, and global uncertainties introduced unprecedented variables into the equation, making it challenging to isolate the TCJA’s direct influence on investment patterns. Additionally, the International Monetary Fund pointed to less robust investment growth post-TCJA than one might expect following previous corporate tax cuts. The IMF attributed this discrepancy to an increase in aggregate demand rather than the tax cuts themselves, suggesting that various macroeconomic factors played more significant roles than the TCJA in influencing investment decisions during this period.

Intellectual Property Investment Dynamics

Investment in intellectual property (IP) significantly outpaced growth in equipment and structures, a trend that began well before the TCJA’s enactment. Contrary to expectations, the act did not accelerate this existing trend. Certain TCJA provisions increased the cost of IP investment, deterring potential growth in this area instead of incentivizing it. These measures appear to have limited IP investment’s role as a driving force behind achieving the Act’s goals. This nuanced outcome emphasizes the complexity of the TCJA’s impact across different types of investments.

Comparisons between Congressional Budget Office (CBO) investment projections and actual data provide further insights. In early 2017, the CBO projected an 8.3% increase in real investment in equipment and structures by the end of 2019. Interestingly, the actual rise was only slightly higher at 8.6%. This marginal deviation underscores the limited extent of the TCJA’s influence on aggregate investment trends. Despite significant tax cuts, the anticipated surge in investment activity did not materialize as substantially as projected, suggesting that other factors may have played a pivotal role in shaping investment dynamics.

International Comparisons and Broader Implications

To assess the TCJA’s broader implications, examining international investment trends provides a valuable context. Data reveals that following 2017, the change in investment as a share of GDP in the United States was not markedly different compared to other Group of 7 (G-7) countries. While the U.S. had the second-highest growth rate in investment/GDP share from 2013 to 2016, post-2016 the growth rate was notably less impressive. From 2016 to 2019, the U.S. ranked fourth among G-7 countries, suggesting that the TCJA did not result in a significant competitive edge in terms of driving investment.

Additionally, real investment growth comparisons further illuminate this observation. Between the 2015-16 and 2018-19 periods, U.S. real investment growth paralleled that of the United Kingdom, surpassing Japan and Canada but falling short when compared to Italy, Germany, and France. These international benchmarks provide a broader perspective on the TCJA’s impact, reinforcing the idea that while some positive effects were observed, they were neither unique nor exceptional when viewed against global investment patterns in comparable economies. These insights underscore the need to consider a wide array of factors when evaluating the efficacy of tax policy in stimulating economic growth.

Factors Influencing Investment Patterns

Among the myriad of factors influencing investment patterns during this period were rising trade tensions and tariffs, alongside specific industry challenges such as the delays with Boeing’s 737 MAX aircraft. These issues contributed to a reduction in GDP growth by an estimated 0.3 percentage points, indicating a tangible effect on investment dynamics. Simultaneously, fiscal policy during this period became more expansionary. The Bipartisan Budget Acts of 2018 and 2019 spurred GDP growth between 0.75 and 1.75 percentage points. Additionally, the federal funds rate was unexpectedly accommodating, remaining at 1.625% by the end of 2019 rather than the projected 2.7%.

Given these positive non-TCJA influences, the overall lack of significant aggregate investment growth likely stems from the redistribution rather than the expansion of investment. There is a possibility that the TCJA effectively shifted investment from smaller non-corporate firms with minor or no tax cuts to larger corporate entities benefitting substantially from the Act. Thus, it seems the TCJA may have facilitated an internal reorganization of investments rather than a substantial increase in overall investment volumes.

Empirical Evidence and Policy Implications

The Tax Cut and Jobs Act (TCJA) of 2017 was presented as a groundbreaking initiative aimed at revitalizing business investment across the United States. By slashing corporate tax rates from 35% to 21%, along with other significant incentives, the legislation sought to make the U.S. a magnet for business investments. Non-corporate businesses also benefited, with their top tax rates dropping from 37% to 29.6%. Furthermore, the TCJA allowed businesses to fully deduct the cost of certain investments upfront, temporarily eliminating the cumbersome depreciation process. These comprehensive changes were designed to stimulate a strong upturn in business investments and, by extension, spur overall economic growth. However, the critical question remains: Did the TCJA successfully fulfill its ambitious goals? This evaluation remains central to understanding the long-term impact of the TCJA on the U.S. economy and its effectiveness in achieving the intended economic revitalization.
