Is a big refund good news?

It is an interest-free loan to the government. Aim for near-zero by tuning W-4 withholding: same pay, no waiting until April.

Does this include state tax?

No — federal only, single filer, 2025 brackets. State rules vary widely, so check your state estimator separately.

What if I itemize instead of the standard deduction?

Enter your total itemized amount as pre-tax deductions and uncheck the standard box. Use whichever total is larger.

About Tax Refund

Estimate a federal refund (or balance due) from income, deductions, and withholding under 2025 single-filer brackets.

A refund is simply overpayment: the gap between what was withheld from paychecks and the actual liability. This calculator rebuilds the liability from your gross income minus pre-tax deductions and the standard deduction, then runs the taxable remainder through the 2025 single-filer federal brackets.

Positive means money back; negative means a balance due. State taxes, credits (child, education, EV), and AMT are outside this estimate — real filings layer those on top. Everything computes in your browser.

Where it is used

W-4 withholding checkups mid-year, last-minute estimated-payment decisions, and sanity-checking tax software before filing.
