2026 Federal Marginal Rate Lookup
Enter your 2026 federal taxable income and filing status to find your marginal rate and the bracket above and below your current position.
How this calculator works
This calculator applies United States (federal)'s progressive tax brackets to the income you enter, moving each dollar through the correct marginal rate until the full amount is accounted for. The effective rate shown at the bottom is the total tax divided by gross income, a useful number for budgeting because it represents what you actually pay on every dollar earned, not just the headline marginal rate. We never apply a flat percentage to total income. Standard deductions and common adjustments are applied in the same order the tax authority applies them, so the result matches the official calculation within rounding error. If you file jointly, select the joint filing status, brackets widen substantially and the difference is meaningful for middle-income households.
Required inputs: taxable income, filing status.

The bracket distance shows how much room you have before crossing into the next bracket. For complete tax computation across federal + state + FICA, use the main 2026 calculator.
