How this calculator works
Calculate progressive federal tax before and after adding income, then subtract. Extra income can span several brackets; multiplying all of it by one marginal rate can give the wrong answer.
Worked example
For a single filer starting at $50,000 taxable income, adding $1,000 raises tax from $5,752 to $5,932. The $180 increase leaves $820 after federal income tax.
What this estimate includes
This estimates income-tax liability, not bonus withholding. Payroll taxes, state taxes, deduction changes and credit phaseouts are excluded.
2026 rules and sources
Rates, thresholds, standard deductions and child-credit amounts use IRS Revenue Procedure 2025-32. See the 2026 federal bracket tables for all filing statuses. Read the full assumptions and sources.
