Joe Biden only wants to repeal parts of the 2017 law which allowed tax cuts and the bulk of the tax increases would impact top earners.
While Joe Biden said that under his tax plan, taxes would not be raised for people earning less than $400,000, CNBC reported that studies from the Tax Policy Center and the Tax Foundation show that his plan could raise middle-class taxes slightly. As workers usually end up paying some portion of higher corporate taxes, they suggest that middle-class taxpayers could see a tax increase of between $180 and $200 a year. However, the Tax Policy Center estimates that the top 1 percent of the wealthiest households would pay three-quarters of the tax increases. The Tax Foundation found that Biden’s plan could also reduce long-run economic growth by 1.51 percent and eliminate about 585,000 full-time equivalent jobs.
Biden’s tax plan will lead to the wealthiest 1 percent bearing much of the tax burden, which indirectly affects the increase in corporate tax of middle-class taxpayers. CNBC reported that an analysis released by the Tax Policy Center in Oct 2020 revealed that top earners would see a steep increase. Those in the top 1%, who earn more than $788,000, would see an average tax increase of $266,000, while the super earners — or those in the top 0.1% — would see an average tax hike of $1.6 million. As far as repealing Trump's tax overhaul laws are concerned, Biden's campaign has clarified that they only want to repeal parts of the law and focus those changes on corporations and households making more than $400,000. The analysis also found that at least in the early years of the tax plan, the impacts of the corporate tax increase would be more than offset by tax credits and deductions aimed at middle- and lower-income earners.
