Introduction
This free tax refund calculator helps you estimate how much money you could get back, or owe, on your federal tax return. Just enter your income, filing status, dependents, and deductions. The calculator uses the official IRS tax brackets and credit rules for the 2024 to 2027 tax years.
For 2027, the IRS standard deduction is $16,600 for single filers and married people filing separately, $33,200 for married couples filing jointly and $24,925 for heads of household, and the 10% bracket covers the first $12,800 of taxable income for single filers ($25,600 for joint filers).11
It figures out your adjusted gross income, picks the better deduction (standard or itemized), and applies credits like the Child Tax Credit and Earned Income Tax Credit automatically. You get a full line-by-line breakdown, bracket-by-bracket details, and step-by-step math so you can see exactly how your result is calculated.
This tool is built for W-2 employees, families with children, retirees, and anyone who wants a quick look at their federal tax picture before they file. It is not a substitute for professional tax advice, but it gives you a solid starting point to plan ahead and avoid surprises at tax time.
How to Use Our Tax Refund Calculator
Enter your income, deductions, credits, and tax payments below. The calculator will estimate your federal tax refund or balance due based on current IRS tax brackets and rules.
Basic Information
Tax Year: Pick the tax year you want to estimate. The calculator updates all brackets, deductions, and credit limits to match the year you choose.
Filing Status: Select how you plan to file your federal return. Choose Single, Married Filing Jointly, Married Filing Separately, Qualifying Surviving Spouse, or Head of Household. Your filing status affects your tax brackets and standard deduction amount. If you file separately and lived with your spouse at any time during the year, the base amount used to figure how much of your Social Security benefits is taxable is $0.17 A separate filer can still claim the child and dependent care credit if their spouse did not live in their home for the last 6 months of the year and they paid more than half the cost of keeping up their home, which was a qualifying person's home for more than half the year.18 A separate filer who lived apart from their spouse for the last 6 months of the year can also claim the Earned Income Tax Credit with a qualifying child who lived with them for more than half the year.19
Your Age: Enter your age. If you are 65 or older, you get a higher standard deduction.
Spouse's Age: Enter your spouse's age if you file jointly. A spouse who is 65 or older also adds to the standard deduction.
Someone Can Claim Me as a Dependent: Check this box if another person claims you on their tax return. This lowers your standard deduction. The calculator then also gives no Child Tax Credit, Other Dependent Credit, education credit, child and dependent care credit or student loan interest deduction. It gives no Earned Income Tax Credit either, unless you have a qualifying child of your own and answer No to the next question.
Could You Be Someone Else's Qualifying Child: This question shows only if someone can claim you as a dependent. With a qualifying child of your own, you can still get the Earned Income Tax Credit if you could not be another person's qualifying child. Without a qualifying child, you cannot get it if someone can claim you as a dependent.
Did You Live With Your Spouse: This question shows only if you choose Married Filing Separately. Your answer sets how much of your Social Security is taxed, whether the Earned Income Tax Credit and the child and dependent care credit can apply, and which IRA deduction range is used.
Children Age 16 or Under: Enter the number of your children who are 16 or younger. Each child may qualify for up to $2,200 in Child Tax Credit for the 2025 tax year.3 The credit is also $2,200 for 2026,1 and it was $2,000 for 2024.12 For 2027 it is $2,300.11
Dependents 17 to 23 (Full-Time Students): Enter the number of dependents between 17 and 23 who are full-time students. They are too old for the Child Tax Credit, which needs a child under 17, but each one may qualify for the $500 Other Dependent Credit.3 A full-time student who is under 24 at the end of the year and younger than you (or your spouse, if you file jointly) can also be a qualifying child for the Earned Income Tax Credit.13
Other Dependents: Enter any other dependents you support. Each one may qualify for a $500 Other Dependent Credit.3
Income and Withholding
Your Wages (W-2 Box 1): Enter your total wages from Box 1 of your W-2 form.
Your Federal Tax Withheld (Box 2): Enter the federal income tax your employer took out of your pay. Find this in Box 2 of your W-2.
Spouse's Wages (W-2 Box 1): If filing jointly, enter your spouse's wages from their W-2 Box 1.
Spouse's Federal Tax Withheld (Box 2): If filing jointly, enter the federal tax withheld from your spouse's W-2 Box 2.

Unemployment Compensation: Enter any unemployment benefits you received during the tax year.
Taxable Interest: Enter interest earned from bank accounts, CDs, or bonds.
Ordinary Dividends: Enter total dividends you received from stocks or mutual funds.
Qualified Dividends: Enter the portion of your dividends that count as qualified. This is a subset of your ordinary dividends. Qualified dividends can be taxed at a lower rate, but this calculator taxes them at ordinary rates, so your actual tax may be lower.
Social Security Benefits: Enter the total Social Security benefits you received. The calculator figures out how much of it is taxable.
IRA / Pension / Annuity: Enter taxable distributions from traditional IRAs, pensions, or annuities.
State/Local Tax Refund: Enter any state or local tax refund you got last year, if it was taxable.
Other Taxable Income: Enter any other income not listed above, such as rental income, gambling winnings, or alimony received under a divorce or separation agreement made before 2019 and not later changed to follow the new rules.16
Your Estimated Payments: Enter the total of all quarterly estimated tax payments you sent to the IRS this year.
Spouse's Estimated Payments: If filing jointly, enter the total estimated tax payments your spouse made.
Deductions and Adjustments
Standard vs. Itemized Deduction: Choose whether you want to compare itemized deductions against the standard deduction. The calculator will use whichever saves you more money.
Mortgage Interest: Enter the mortgage interest you paid on your home loan during the year.
State and Local Taxes (SALT): Enter the state and local income or property taxes you paid. The cap is $40,000 for 2025 and $40,400 for 2026, half of that for Married Filing Separately, and it shrinks by 30 percent of income above $500,000 (2025) or $505,000 (2026) but never below $10,000.5 Before 2025 the cap was $10,000 ($5,000 for Married Filing Separately).5 After 2026 and before 2030, both dollar amounts rise each year to 101 percent of the amount for the year before.5 That makes the 2027 cap $40,804, shrinking above $510,050.
Charitable Donations (Cash): Enter cash donations you made to qualified charities.
Charitable Donations (Non-Cash): Enter the fair market value of items like clothes or furniture you donated to charity.
Medical Expenses: Enter your total medical expenses. Only the amount that exceeds 7.5% of your adjusted gross income counts as a deduction.7
Other Itemized: Enter any other itemized deductions not listed above.
Traditional IRA Contributions: Enter the amount you put into a traditional IRA for the tax year. If you or your spouse was covered by a retirement plan at work, your deduction may be reduced or eliminated, depending on your filing status and income.14
Spouse IRA Contributions: If filing jointly, enter your spouse's traditional IRA contributions.
Covered by a Retirement Plan at Work: Answer for yourself and, if you are married, for your spouse. The calculator applies the IRS deduction phase-out range for the tax year you pick and shows the range under the IRA box. For 2027 it uses the 2026 limits and ranges until the 2027 figures are announced.
Student Loan Interest: Enter interest paid on qualified student loans, up to $2,500.8 This deduction phases out at higher income levels. You cannot take it if your filing status is Married Filing Separately or if someone claims you as a dependent.8
Educator Expenses: If you are a teacher, enter out-of-pocket classroom expenses. You can deduct up to $300 ($600 if both spouses are teachers, but not more than $300 each).9 For 2026 the limit is $350.1 It is $350 for 2027 too.11 If both spouses teach, the joint limit for those years is $700.
Tax Credits
Child and Dependent Care Expenses Paid: Enter what you paid for daycare, after-school care, or other dependent care so you could work. The care must be for a child under 13, or for a spouse or dependent who is not able to care for themselves.18 Expenses count up to $3,000 for one qualifying person or $6,000 for two or more, and not more than your earned income (the smaller of your and your spouse's earned income if you are married).18 A spouse who was a full-time student or not able to care for themselves is treated as earning at least $250 a month, or $500 a month with two or more qualifying persons.18
Qualifying Persons for Care: Enter how many qualifying people the care was for. The calculator uses this number, not your count of children, to set the expense limit.
Months a Spouse Was a Student or Unable to Care for Self: This box shows only on a joint return. Enter the months the spouse with less earned income was a full-time student or could not care for themselves. For each of those months the calculator counts that spouse as earning at least $250, or $500 with two or more qualifying persons.
Qualified Education Expenses: Enter tuition and fees paid for college or other higher education. The calculator picks the better credit for you: American Opportunity or Lifetime Learning. The American Opportunity Credit is up to $2,500 per eligible student.15 You cannot claim either credit if your filing status is Married Filing Separately or if you are claimed as a dependent on another person's return.15
Students With These Expenses: Enter how many students the education expenses were for. The calculator splits the expenses evenly between them.
Home Energy Improvements: For 2024 and 2025, enter what you paid for new clean energy property for your home, such as solar electric panels, solar water heaters, wind turbines, geothermal heat pumps, fuel cells or battery storage. The credit equals 30% of those costs.10 The credit is not available for any property placed in service after December 31, 2025.10
Other Federal Tax Credits: Enter any other federal tax credits not already covered above.
How This Federal Tax Refund Calculator Works
This free tax refund calculator estimates how much money you could get back, or owe, on your federal tax return. It uses the official IRS tax brackets, standard deduction amounts, and credit rules for the 2024 to 2027 tax years. Just enter your income, filing status, dependents, and any deductions or credits you qualify for. The calculator works out your estimated refund or the amount you still owe.
What Is a Tax Refund?
A tax refund is money the government sends back to you. It happens when you paid more in taxes during the year than you actually owe. Most people pay taxes through withholding: money your employer takes out of each paycheck and sends to the IRS. If too much was taken out, the IRS gives the extra back as a refund. If too little was taken out, you owe a balance due.
What Affects Your Refund Amount
Several things change how big your refund is or whether you owe money:
- Filing status: Single, Married Filing Jointly, Head of Household, and other statuses each have different tax brackets and deduction amounts.
- Income: Wages, self-employment pay, interest, dividends, Social Security benefits, and other earnings all count toward your total taxable income.
- Deductions: The standard deduction lowers your taxable income automatically. If your itemized deductions (like mortgage interest, state taxes, and charity) add up to more, you can use those instead.
- Tax credits: Credits directly reduce the tax you owe, dollar for dollar. The Child Tax Credit, Earned Income Tax Credit (EITC), education credits, and energy credits can all shrink your tax bill or increase your refund.
- Withholding and estimated payments: The total amount you already paid to the IRS during the year is compared to your final tax. The difference is your refund or balance due.
