How do you estimate your tax refund from your pay stubs?
Add up year-to-date federal withholding, estimate your actual annual tax from the brackets, and subtract. If your last stub shows $7,200 withheld and your real tax on $70,000 is about $7,400, you're on track for a small bill — not a refund.
Refund estimate worksheet, single filer (2025)
| Step | Example | Where to find it |
|---|---|---|
| Project annual gross | $70,000 | YTD gross ÷ periods elapsed × 26 |
| Compute actual tax | $7,450 | Brackets after $15,000 std deduction |
| Project annual withholding | $7,200 | YTD FITW scaled the same way |
| Estimated refund / (bill) | ($250) | Withholding − actual tax |
How to read this table
- Project annual gross sits at the top of the table ($70,000) — ytd gross ÷ periods elapsed × 26. If your situation looks like this row, plan against the upper half of the range rather than the midpoint.
- Estimated refund / (bill) anchors the bottom (($250)) — withholding − actual tax. Treat this as the conservative case you should still be profitable at.
- The gap between the top and bottom row is roughly 280×. That spread is why a single blended average is close to useless here — pick the row that matches your setup instead of averaging the column.
- With 4 reference points in the "refund estimate worksheet, single filer (2025)" table, the fastest way to use this page is to find the closest row, take its example, then stress-test it ±30% before you build a plan on it.
Context
A big refund means you gave the government an interest-free loan — the average US refund is around $3,000, which is $250/month of take-home you could have had all year. Aim for a small refund or small bill by adjusting your W-4 (the IRS Tax Withholding Estimator does this precisely). Credits change everything: the Child Tax Credit ($2,000 per child) and Earned Income Credit can produce a refund larger than everything you withheld.
What moves this number
Filing status and W-4 settings
Married filing jointly roughly doubles bracket widths and the standard deduction, so the same salary withholds very differently by status. Dependents, second jobs, and extra-withholding entries on the W-4 move every paycheck.
State and local taxes
Nine states levy no wage income tax while top marginal rates elsewhere exceed 10%, and cities like New York add their own layer. The same salary can differ by hundreds of dollars per month purely on location.
Pre-tax benefits
Traditional 401(k), HSA, and health premiums come out before income tax, shrinking both taxable income and the withholding on each check — a raise in contributions costs less take-home than the headline amount.
Methodology
Estimate = projected annual withholding − (bracket tax on projected taxable income − credits). 2025 single brackets and $15,000 standard deduction used in the example.
Assumptions and caveats
- Figures use current-year federal brackets and standard deductions; your actual withholding depends on your W-4 and state.
- Estimates exclude credits (Child Tax Credit, EITC), which can materially change the final number.
- This is educational arithmetic, not tax advice — confirm decisions with a tax professional.
- This page was last reviewed on 2026-10-01. Ranges are updated as new data lands, so re-check before using them in a contract or a plan.
- Use these numbers as a starting range, not a guarantee — your own historical data always beats a benchmark.
Frequently asked questions
How do you estimate your tax refund from your pay stubs?
Add up year-to-date federal withholding, estimate your actual annual tax from the brackets, and subtract. If your last stub shows $7,200 withheld and your real tax on $70,000 is about $7,400, you're on track for a small bill — not a refund.
Which option pays the most in the refund estimate worksheet, single filer (2025) table?
Project annual gross, at $70,000 (YTD gross ÷ periods elapsed × 26). That row represents the strongest case in this dataset, so use it as an upper bound rather than an expectation.
What is a realistic low-end figure?
Estimated refund / (bill) at ($250) (Withholding − actual tax). Plan your costs so the low end still works, then treat anything above it as upside.
Why do the numbers vary so much?
The spread between the highest and lowest row is about 280×. Filing status and W-4 settings and state and local taxes explain most of that gap — see the drivers section above for the full list.
Where do these numbers come from?
Estimate = projected annual withholding − (bracket tax on projected taxable income − credits). 2025 single brackets and $15,000 standard deduction used in the example.
How can I estimate my own number instead of using a benchmark?
