What is the range of tax brackets for federal income tax rates in the U.S.?

The range of tax brackets for federal income tax rates in the U.S. includes rates of 10%, 12%, 22%, and 24%. This range reflects the progressive tax structure that is designed to tax individuals based on their income levels.

The first bracket starts at 10% for lower income levels, gradually increasing to higher percentages as the taxpayer's income rises. The subsequent brackets—12%, 22%, and 24%—apply to progressively higher income thresholds. This means that as a taxpayer moves into higher brackets, only the income that exceeds previous bracket thresholds is taxed at the higher rates.

These brackets are part of the system that ensures individuals contribute to federal income taxes in a manner that corresponds with their ability to pay. By utilizing this progressive methodology, the U.S. tax system aims to balance equitable taxation with revenue generation for federal programs and services.
