How much federal tax will I owe for 2025?
Estimate your federal tax liability for 2025 or 2026 by entering income, deductions, and credits. The tool applies IRS brackets and standard deduction rules to show total tax before payments, helping you plan withholding or estimated payments and avoid surprises at filing time.
How this calculation works
- Estimates taxable income after deductions and adjustments.
- Applies the correct IRS bracket schedule for the selected filing status.
- Subtracts credits to estimate total tax liability.
Common mistakes and caveats
- Does not model every credit limitation or phaseout.
- AMT, net investment income tax, and self-employment tax may change results.
- Always compare with IRS forms before filing.
FAQ
Does this include credits like the Child Tax Credit?
Yes, if you enter them. Credits reduce the total tax estimated by the calculator.
Is this my final tax bill?
No. This is an estimate and does not replace official IRS calculations or forms.
