FAQ
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate applied to your last dollar of income, while your effective tax rate is the overall average rate you pay on all your income. Due to progressive brackets, your effective rate is always lower than your marginal rate.
What is the standard deduction?
The standard deduction is a fixed amount that reduces your taxable income. For 2024, it is $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household. You can choose to itemize deductions instead if they exceed the standard amount.
Does this calculator include state taxes?
No, this calculator estimates federal income tax only. State income tax varies widely and some states have no income tax at all. Check your state tax authority for state-specific calculations.
