What is Tax bracket?

A tax bracket is a range of income taxed at a specific rate. The U.S. has seven brackets, from 10% to 37%. In the United States, federal income tax is progressive, meaning that as taxable income increases, it is taxed at higher marginal rates. Currently, there are seven federal tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Tax brackets are adjusted annually by the IRS for inflation to prevent 'bracket creep,' where inflation-driven wage increases push taxpayers into higher tax brackets without a real increase in purchasing power.

Income within a tax bracket is only taxed at that bracket's specific rate. For example, in the 2026 tax year, single filers pay 10% on their first $12,400 of taxable income, and 12% on income between $12,401 and $50,400. Tax brackets vary significantly based on filing status, such as Single, Married Filing Jointly, or Head of Household.

Understanding tax brackets helps taxpayers optimize their tax planning. By deferring income or maximizing deductions, individuals can prevent their last dollar of income from crossing into a higher tax bracket, reducing their total tax liability.
