FAQ

What does this calculator include?
It estimates 2024 US federal income tax only, using the standard deduction for your filing status. It excludes state tax and credits — this is not tax advice.
How is taxable income calculated?
Taxable income = gross income − the 2024 standard deduction for your filing status ($14,600 single, $29,200 married, $21,900 head of household), floored at zero.
What is the difference between effective and marginal rate?
The effective rate is your total federal tax divided by gross income. The marginal rate is the bracket rate applied to your last dollar of taxable income.
