How Has the Tax Cuts and Jobs Act Affected the US Economy?
The economy initially grew, but the pandemic complicated things
Critics of President Donald Trump’s tax plan to significantly reduce business and personal taxes warned that the cuts would send the deficit skyrocketing by dramatically shrinking federal revenues. Proponents argued that the tax cuts would spur economic growth that would more than pay for the loss of revenue. The Tax Cuts and Jobs Act (TCJA)—reflecting President Trump's plan—was ultimately signed into law on Dec. 22, 2017. It went into effect on Jan. 1, 2018. Since then, the debt-to-gross domestic product (GDP) ratio decreased slightly before resuming its upward trajectory by the end of 2019.
While the fourth quarter of 2020 saw a 4% increase in the U.S. economy, according to the Bureau of Economic Analysis, the overall year's GDP actually contracted by 3.5%. However, the impact of the COVID-19 pandemic may make it difficult to determine what role the TCJA played in the GDP decrease.
Here are some impacts of the TCJA to consider.
The Effect of Tax Brackets
President Trump initially proposed to lower income taxes and reduce the number of tax brackets from seven to three—12%, 25%, and 35%. That didn't happen. The TCJA still provides for seven brackets, but they've been reduced somewhat: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.
The brackets in 2017, before the TCJA, were: 10%, 15%, 25%, 28%, 33%, 35%, and 39.6%.
The Standard Deductions
President Trump also wanted larger standard deductions, and he got them. The standard deduction nearly doubled under the TCJA. In 2021, the standard deductions are $25,100 for married couples filing jointly, $12,550 for single filers, and $18,800 for heads of household.
However, while the TCJA significantly increased the standard deduction, it also eliminated the personal exemption that filers could take for themselves, their spouses, and each of their dependents. Personal exemptions are unavailable from 2018 through 2025. In 2025, many aspects of the TCJA are scheduled to expire unless Congress acts to renew the law.
Some individuals and families may find that the increased standard deduction more than makes up for the loss of personal exemptions. Others may find that they ultimately pay more in taxes than they would have if they could have claimed personal exemptions.
Individual Taxes Overall
Before the TCJA took effect, the Tax Policy Center estimated that the tax cuts would result in an average tax reduction of $1,600. However, most of those benefits were expected to be enjoyed by high-income families with more than $300,000 in annual income. While middle-income families were expected to pay about $900 less in taxes, those in the top 0.1% of earners were expected to receive an average tax cut of about $190,000.
Those estimates appear to be playing out as expected. In 2020, the Tax Foundation reviewed income tax data from the 2019 fiscal year and found that the average American paid about 2% fewer taxes than they did before the TCJA. The average tax wedge was 29.8% in 2019, compared to 31.8% in 2017.
The TCJA slashed the corporate tax rate from 35% to 21%. In 2017, the tax receipts on corporate income stood at $245.4 billion. In 2018, that number fell to $210.5 billion in 2018, despite 3% GDP growth. In 2019, that figure increased somewhat to $217.3 billion—still more than $35 billion less than corporate tax revenue in 2017.
The Tax Policy Center believes that in the short term, at least, the TCJA will stimulate the economy. However, the long-term stimulating effects—especially compared to deficit issues—are less certain. The GDP's rate of growth increased in 2018 (from 2.3% to 3%), but the rate of growth slowed in 2019 (down to 2.2%), and in 2020 the GDP didn't grow at all—it shrank by 3.5%.
The Effect on the Federal Deficit
Official estimates found that the TCJA would have been expected to add between $1 trillion and $2 trillion to the federal deficit before 2025. However, the COVID-19 pandemic and federal spending in response increased the federal deficit much more quickly. It's now much more difficult to determine what the deficit would have been as a result solely of the TCJA. As of October 2020, the federal deficit was more than $3.1 trillion. In 2017, the deficit was $665 billion.
The Bottom Line
While analysts generally agree that the TCJA reduced income tax burdens for most Americans as expected, the more nuanced questions—whether it would pay for itself and stimulate the economy—still haven't been answered. At this point, complete tax and economic data are only available for two post-TCJA years. As more tax and economic data become available, it will be easier to make more conclusive statements about what the impact of the TCJA has been.
The COVID-19 pandemic has only further complicated these considerations. Not only did the recovery spending throw an unexpected wrench into the TCJA's deficit projections, but many businesses were forced to close or operate at a reduced capacity to help slow the spread of the virus. Had those businesses operated as usual, and had the government not been forced to increase deficit spending, 2020's GDP data could have played out much differently.
