Frequently Asked Questions
What tax brackets does this calculator use?
This calculator uses the 2024 federal income tax brackets published by the IRS. The brackets are adjusted for inflation each year and vary based on your filing status (Single, Married Filing Jointly, or Head of Household).
What is the difference between effective and marginal tax rate?
Your marginal tax rate is the rate at which your last dollar of income is taxed — the highest bracket you fall into. Your effective tax rate is the average rate across all your income, calculated as total tax divided by gross income.
What is the difference between standard and itemized deductions?
The standard deduction is a fixed amount based on your filing status ($14,600 for Single in 2024). Itemized deductions let you deduct specific expenses like mortgage interest, state taxes, and charitable donations. Choose whichever gives you the larger deduction.
How are tax credits different from deductions?
Tax deductions reduce your taxable income, while tax credits reduce your tax bill dollar-for-dollar. A $1,000 tax credit saves you $1,000 in taxes, whereas a $1,000 deduction saves you between $100-$370 depending on your tax bracket.

Does this cover state taxes?
This calculator currently estimates federal income tax only. State tax rates vary widely by state and are not included. For a complete picture, you would need to calculate state taxes separately based on your state of residence.
