Personal Finance Insider's free federal income tax calculator estimates how much you may owe the IRS, or get back as a refund, when you file your 2021 tax return. Our estimate is based on information you provide about your filing status, income, retirement contributions, tax withholding, deductions, and dependents.
Income: Your gross income for the tax year, as well as how much you contributed to a 401(k) or traditional IRA. (Note: We included these above-the-line deductions because they're common. When you prepare your tax return, you might also qualify to write off other items, such as student-loan interest or half of your self-employment taxes, that will ultimately lower your taxable income).
Dependents: How many dependents you claim. (Note: We considered dependents to be children 17 and under who qualify for the child tax credit. When you enter a dependent in this field of the calculator, it triggers a $3,000 tax credit. If you already received part of your 2021 child tax credit payments as advance monthly payments, you'll need to subtract that amount from your total refund).
