How to use the Tax Refund Calculator
Choose the tax year and filing status of the return you are estimating.
Enter your income and any pre-tax 401(k), HSA or IRA contributions.
Enter the federal income tax withheld: box 2 of each W-2 (or the year-to-date amount on your last pay stub) plus any 1099 withholding, and estimated payments you sent.
Add dependents, age 65+ filers and deductions, plus any other credits you expect, such as the earned income credit.
Press Calculate to see your refund or the amount you owe, with a line-by-line breakdown.
Total tax is your bracket tax on taxable income minus nonrefundable credits. A positive result is a refund; a negative result is what you pay when you file.
Example (2026, married filing jointly, two children): $95,000 of wages − $5,000 of 401(k) = $90,000 AGI. Minus the $32,200 standard deduction leaves $57,800 taxable, and the bracket tax is $2,480 + $3,960 = $6,440. Two child credits ($4,400) cut that to $2,040. With $5,200 withheld, the refund is about $3,160.

Tips before you file
Use your final pay stub for year-to-date withholding if your W-2 has not arrived.
Don't forget withholding on 1099s, such as unemployment benefits or retirement distributions.
Check refundable credits. The earned income credit can be worth several thousand dollars for working families with modest income.
Owe money? File on time even if you can't pay in full; the failure-to-file penalty is much larger than the late-payment penalty.
Adjust your W-4 after a big refund or a bill so next year comes out close to even.
Frequently asked questions
How is a tax refund calculated?
Your refund is the total of what you already paid (paycheck withholding, estimated tax payments and refundable credits) minus your total tax for the year. If payments are larger you get the difference back; if they are smaller you owe the difference when you file.
Where do I find how much federal tax was withheld?
Box 2 of your Form W-2 shows federal income tax withheld for the year. Before you get your W-2, use the year-to-date federal withholding on your latest pay stub and add what you expect to be withheld from the remaining paychecks. Withholding on 1099 forms is in box 4.
Why is my refund smaller than last year?
Common reasons are lower withholding after a W-4 change or raise, losing a dependent or credit, more income from a side job with no withholding, or a change in filing status. Compare the line-by-line tables for both years to see which line moved.
Is the child tax credit refundable?
Partly. For 2025 and 2026 the credit is $2,200 per child under 17, and up to $1,700 per child can be paid to you as the Additional Child Tax Credit even if you owe no tax, limited to 15% of earned income above $2,500. The calculator adds that refundable part to your payments.
Will I pay a penalty if I owe?
Usually not if you owe less than $1,000, or if your withholding and estimated payments covered at least 90% of this year's tax or 100% of last year's tax (110% if last year's AGI was over $150,000). Otherwise the IRS may charge an underpayment penalty on Form 2210.
When will I get my refund?
The IRS says most e-filed returns with direct deposit are refunded within 21 days. Returns claiming the earned income credit or the additional child tax credit cannot be refunded before mid-February by law.
Is a big refund good?
A refund means you lent the government money interest-free during the year. If you would rather have the money in each paycheck, lower your withholding on Form W-4; the W-4 withholding calculator on this site suggests the entries.
