Common Questions
What's the difference between marginal and effective tax rate?
Marginal rate is your tax bracket rate (24%, 22%, etc.). Effective rate is total tax ÷ income. Always think in terms of effective rate when planning.
Should I itemize or take the standard deduction?
Standard deduction is $16,100 (single) in 2026. Itemize only if deductions (mortgage interest, charity) exceed this.
What about state and local taxes?
This calculator shows federal only. State income tax ranges 0–13%; add that separately based on your state.

- Your effective tax rate is lower than your marginal rate—the US uses progressive taxation.
