Tax policy discussions regarding the wealthy typically focus on how much affluent households should pay relative to other households. For example, President Biden stated, “Let’s make corporations and wealthy Americans start paying their fair share” in his 2022 State of the Union address. Similarly, criticism of the Tax Cuts and Jobs Act of 2017 (TCJA) often centers on how it disproportionately reduced taxes for high-income households.
These arguments agree that the wealthy should pay more in taxes, but the current debate has focused less on how to structure the taxation of high-income households. The structure of taxes is important because while typical American households primarily earn income in the form of wages and salaries, affluent households typically receive a much greater share of their income in the form of returns to capital. As a result, the taxation of these households can have a meaningful impact on neutrality and efficiency of the overall tax code.
The taxation of the wealthy can create distortions which can influence numerous taxpayer choices and thus affect economic efficiency and horizontal equity. Although changes to the tax system over the past several decades have greatly reduced these economic distortions, there is still room for improvement. Fundamental tax reform could further reduce or eliminate these distortions.
