Research indicates that many Americans misunderstand the tax system, contributing to dissatisfaction with taxes, as a Cato Institute survey reveals that 55% of taxpayers feel they pay too much. Despite the progressive nature of the tax code, which sees the top 10% of earners paying 72% of federal income taxes, a significant portion of the population lacks clarity on tax brackets, with many mistakenly believing their top marginal rate applies to all their income. This lack of understanding highlights a gap between personal finance awareness and the complexities of federal taxation.
