Frequently asked
What deduction figure should I use?
It's pre-filled with the 2024 standard deduction for your filing status. Replace it with your itemized total if that's larger and you plan to itemize instead.
Does this include state income tax?
No. This is federal tax only. Use the US Paycheck Calculator for an estimate that also factors in a flat state tax rate and FICA.
What's the difference between effective rate and marginal rate?
The marginal rate is the rate applied to your last dollar of taxable income (your top bracket). The effective rate is your total tax divided by your gross income. The average rate across all your income, always lower than the marginal rate.
Is this tax advice?
No. It's an estimate using 2024 federal brackets, for planning purposes only. Consult a tax professional for your actual filing.
