The Tax Cuts and Jobs Act (TCJA), signed into law by President Donald Trump in December 2017, significantly reduced the corporate tax rate from 35% to 21%. This change was intended to stimulate economic growth by increasing corporate profits and investment. However, the TCJA also had a number of other effects, including a decrease in tax revenue and an increase in the federal deficit.

Supply-Side Effects of the TCJA
The TCJA had a number of supply-side effects, which are effects that occur on the side of the economy that produces goods and services. These effects include:
-
Increased corporate profits: The TCJA reduced the corporate tax rate, which led to an increase in corporate profits. According to the Congressional Budget Office (CBO), corporate profits increased by 10.9% in 2018, the first full year after the TCJA was enacted.
-
Increased investment: The TCJA also led to an increase in investment. According to the CBO, investment increased by 5.4% in 2018. This increase in investment is likely due to the fact that the TCJA made it more profitable for businesses to invest in new equipment and facilities.
-
Increased economic growth: The TCJA is estimated to have led to a small increase in economic growth. The CBO estimates that the TCJA increased GDP by 0.7% in 2018. This increase in GDP is likely due to the fact that the TCJA increased corporate profits and investment.
Demand-Side Effects of the TCJA
The TCJA also had a number of demand-side effects, which are effects that occur on the side of the economy that consumes goods and services. These effects include:
-
Increased consumer spending: The TCJA increased the after-tax income of consumers, which led to an increase in consumer spending. According to the CBO, consumer spending increased by 2.9% in 2018. This increase in consumer spending is likely due to the fact that consumers had more money to spend after taxes.
-
Increased inflation: The TCJA also led to an increase in inflation. According to the Bureau of Economic Analysis (BEA), inflation increased by 2.4% in 2018. This increase in inflation is likely due to the fact that the TCJA increased consumer spending and demand for goods and services.
