Frequently Asked Questions
What are the 2024 federal tax brackets? +
For single filers, the 2024 brackets are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Each bracket applies only to income within that range, not your entire income.
What is the difference between effective and marginal tax rate? +
Your marginal rate is the bracket your last dollar of income falls in. Your effective rate is your total tax divided by total income, which is always lower than the marginal rate.
How does the standard deduction affect my taxes? +
The standard deduction reduces your taxable income before brackets are applied. For 2024, it is $14,600 for single filers and $29,200 for married filing jointly.
Does this include state income tax? +
No. This calculator covers federal income tax only. State taxes vary widely and some states have no income tax at all.
