TopToolsAiEstimate your US federal income tax based on your taxable income and filing status, using the current marginal tax bracket structure. A single filer earning $60,000 taxable income falls across two or three federal brackets rather than one flat rate — only the portion of income within each bracket is taxed at that bracket's rate, which is why an effective tax rate always comes out lower than the top marginal rate.

Frequently asked questions
Does this include state income tax?
No, this covers federal tax only — state tax rules and rates vary and would need to be calculated separately.
What is a marginal tax bracket?
It means only the portion of your income that falls within each bracket is taxed at that bracket's rate, not your entire income at the highest rate you reach.
Does this apply the standard deduction?
No, as noted above the result — this is a rough estimate on your entered taxable income without applying the standard deduction automatically.
Does filing status really change the tax owed?
Yes significantly — bracket thresholds differ substantially between Single, Married Filing Jointly, and Head of Household, so the same income can produce different tax amounts.
