Tax Bracket Widths by Year

How the dollar range covered by each federal tax bracket grew from 2020 to 2026, as the IRS adjusted thresholds for inflation.

Key findings

  • The 10% bracket widened by 25.6% from 2020 to 2026. For single filers, it grew from $9,875 to $12,400, an increase of $2,525. The table is derived directly from the same published IRS thresholds used throughout this site.
  • The 22% bracket is the widest bounded bracket in the latest table. In 2026 it covers $55,300 of taxable income for a single filer. The page shows the full threshold range so readers can compare the published schedule rather than infer a rate from a single boundary.
  • Bracket widths grow at different rates. The 35% bracket grew by 23.6% over the same period, from $311,050 to $384,375. Annual inflation adjustments do not move every threshold by the same dollar amount.
  • A bracket width is the span between two published thresholds. It is not a tax estimate: deductions, credits, filing status, and other rules can change an individual result. Use the linked comparison tool only to inspect the published schedules for two years.

Methodology

Bracket widths are calculated as the difference between consecutive published thresholds for single filers. For example, the 2026 12% bracket width is the difference between its upper threshold and the 10% bracket ceiling. The IRS sets these thresholds annually through its inflation-adjustment publications. This table is a reference to those published bands; it does not calculate an individual's tax liability. Use the Bracket Comparison Tool to inspect two source-backed schedules side by side.
