Frequently Asked Questions

What is the difference between marginal and effective tax rate?
Your marginal rate is the rate applied to your last dollar of income (your highest bracket). Your effective rate is your total tax divided by total income — it is almost always lower than your marginal rate because lower income tiers are taxed at lower rates.
Does this include state income tax?
This calculator estimates federal income tax only. State taxes vary widely and require separate calculation based on your state of residence.
How accurate is this estimate?
The estimate applies current federal tax brackets and the standard deduction. It does not account for tax credits, additional withholding adjustments, or AMT. For official tax preparation, always consult a CPA or use IRS tools.
