Tax Bracket
Definition
A tax bracket is a range of taxable income subject to a specific tax rate under a progressive tax system.
Detailed Explanation
Tax brackets are used in progressive tax systems to apply increasing tax rates as taxable income rises. Each bracket defines a range of income and the corresponding percentage of tax owed on income within that range. Tax brackets ensure that individuals with higher incomes pay a larger percentage of their income in taxes compared to those with lower incomes, promoting fairness and equity in the tax system.
In the United States, the federal income tax system has several tax brackets, with rates ranging from 10% to 37% as of 2025. These brackets vary by filing status (e.g., single, married filing jointly, head of household) and are adjusted annually for inflation. Importantly, only the income within a particular bracket is taxed at that rate, not the entire taxable income. This structure means that taxpayers benefit from lower rates on the first portions of their income, regardless of their total earnings.
Tax brackets differ for federal, state, and local taxes. While most states also use progressive systems, some employ flat tax rates. Understanding tax brackets helps individuals estimate their tax liability and plan their finances more effectively.
Example
A single filer in 2025 with $50,000 in taxable income would fall into the 22% federal tax bracket. However, their income would be taxed incrementally: 10% on the first $11,000, 12% on income between $11,001 and $44,725, and 22% on income from $44,726 to $50,000.
