Tax Refund Calculator
Estimate your federal tax refund or balance due by entering your tax liability, withholding, and eligible credits including the Child Tax Credit and EITC. Ideal for use after receiving your W-2 but before filing your return.
About this calculator
Your refund (or amount owed) equals total payments minus your total tax liability. Total payments include federal taxes withheld from your paycheck, any estimated tax payments you made during the year, and refundable tax credits. The Child Tax Credit is worth up to $2,000 per qualifying child, phasing out above $400,000 of income. The Earned Income Tax Credit (EITC) provides up to $3,995 for workers with at least one child earning under $25,220, or up to $600 for childless workers earning under $19,330. The core formula is: Refund = (federalWithheld + estimatedPayments + credits) − totalTaxLiability. A positive result means you get a refund; a negative result means you owe additional tax.
How to use
Suppose your total tax liability is $4,500, you had $5,200 withheld from your paychecks, made $0 in estimated payments, earned $22,000, and have 1 qualifying child. Child Tax Credit = min(1 × $2,000, ...) = $2,000 (no phase-out at this income). EITC = min($3,995, $22,000 × 0.34) = $3,995. Total payments = $5,200 + $0 + $2,000 + $3,995 = $11,195. Refund = $11,195 − $4,500 = $6,695. You would expect a $6,695 federal refund.
Frequently asked questions
How does the Earned Income Tax Credit affect my tax refund amount?
The EITC is a refundable credit, meaning it can increase your refund beyond what you paid in taxes. For workers with at least one qualifying child earning up to $25,220, the credit equals 34% of earned income, capped at $3,995. Even if your tax liability is zero, the IRS will send you the full credit as a refund. The credit phases out entirely above the income threshold.
What is the difference between tax liability and federal taxes withheld?
Tax liability is the total amount of tax you legally owe on your income for the year, calculated from your taxable income and the IRS tax brackets. Federal taxes withheld is the amount your employer already sent to the IRS on your behalf throughout the year. If withholding exceeds liability, you receive a refund of the difference. If liability exceeds withholding, you owe the balance when you file.
When should I use a tax refund calculator instead of waiting to file?
A tax refund calculator is most useful in January or February after you receive your W-2 but before you file your return. It helps you decide whether to file quickly to receive a refund sooner or to take more time gathering deduction records. It is also useful mid-year to adjust your W-4 withholding if you want to avoid a large balance due next April. However, the calculator provides an estimate — your actual refund is determined by your official tax return.
