2025 Tax Refund Estimator
Enter your annual income, the federal tax already withheld from your paychecks, and your filing status to estimate your federal refund — or what you might owe — for the 2025 tax year.
Estimate only, using 2025 federal brackets and the standard deduction for returns filed in early 2026. It assumes the standard deduction and does not include state taxes, itemized deductions, self-employment tax, or every credit. Use IRS forms or a tax professional for an exact figure.
How a tax refund works
Throughout the year, your employer withholds federal income tax from each paycheck and sends it to the IRS on your behalf (shown in Box 2 of your W-2). When you file your return, the IRS compares what you paid against what you actually owe based on your taxable income.
Refund = federal tax withheld − federal tax owed
A large refund means you over-withheld and effectively gave the government an interest-free loan; owing a large balance means you under-withheld. Adjusting your W-4 can bring your withholding closer to your actual tax.
