How should I fill out my W-4 for 2025?
Estimate federal withholding per paycheck and W-4 adjustments by entering income, deductions, credits, and current withholding. The calculator projects your year-end tax and compares it to payments so you can target a smaller refund or balance due for 2025 or 2026.
How this calculation works
- Projects annual income from paycheck inputs.
- Estimates tax using IRS brackets, deductions, and credits.
- Calculates a per-paycheck withholding target to meet the projected tax.
Common mistakes and caveats
- Multiple jobs, bonuses, or irregular income can change results.
- State withholding rules are not included here.
