Frequently asked questions
Is this an official tax filing tool?+
No. This is a simplified estimate using federal marginal tax brackets only — it doesn't account for deductions, credits, state tax, or self-employment tax. Use official IRS tools or a tax professional for actual filing.
What does "marginal tax bracket" mean?+
Only the portion of income within each bracket is taxed at that bracket's rate — moving into a higher bracket doesn't raise the tax rate on your entire income, only on the amount above that threshold.
