About This Federal Tax Estimator
- What it estimates: This calculator provides a rough estimate of your U.S. federal income tax and payroll taxes (FICA) based on standard tax brackets and standard deductions.
- Scope limitations: It covers federal taxes only. It does not include state taxes, local taxes, self-employment taxes, capital gains, Alternative Minimum Tax (AMT), or Qualified Business Income (QBI) deductions.
- Deductions & Credits: It allows simple entry of itemized deductions and non-refundable tax credits (credits cannot reduce income tax below zero in this model). It does not calculate complex phase-outs for credits.
- Payroll taxes: If you enter W-2 wages, it estimates Social Security (6.2% up to the wage base), Medicare (1.45%), and the Additional Medicare Tax (0.9% over thresholds based on filing status).
- Sources: Calculations use the official IRS tax brackets and standard deduction amounts for the selected year. 2026 values may use 2025 proxies until official IRS inflation adjustments are released.
- Not a precise return: Your actual tax return will likely differ due to specific credits, phase-outs, and other income types not modeled here.

Can a tax estimator help before filing season?
Yes. It can help you preview your tax situation earlier so you can adjust withholding, savings, or timing before filing.
Why is my refund estimate different from my paycheck?
Your paycheck withholding is only an estimate during the year. Your final refund or amount owed depends on your full-year income, filing status, and withholding already paid.
