W-2 Tip Check
Check what your employer put on your W-2 against the tips you actually got. Spot any undercount before you file.
Reconciliation only — not tax advice. If your tracked tips exceed Box 7 by a meaningful amount, talk to your employer and a tax professional. Unreported tips may need Form 4137.

How this is calculated
- Subtract tip-out from your tracked tips → net tracked tips.
- Compare net tracked to W-2 Box 7.
- If net tracked is higher, your employer undercounted — talk to payroll.
- If Box 7 is higher, cash, pooled, or reclassified tips can usually explain it.
This number is only as good as your records

FAQ
What is W-2 Box 7?
Box 7 reports Social Security tips — the tips your employer was told about and used for FICA. It does not always match every tip you actually received, especially cash tips you could not report at the time.
What if Box 7 is too low?
Talk to payroll first. If a meaningful gap remains, talk to a tax professional — unreported tips may need to be reported on Form 4137.
Does Box 7 affect the No Tax on Tips deduction?
For 2025, the deduction is self-substantiated — you report qualified tips on your return based on your records. Beginning 2026, qualified tips will appear separately on the W-2 in Box 12 (code "TP").
What this tool actually does
Your W-2 has a box labeled Box 7 — Social security tips. That’s the dollar figure your employer told the IRS about for FICA purposes. It’s not always the same as the tips you actually received — especially if cash tips slipped through, or if a tip pool got reclassified, or if a manager rounded down somewhere.
This tool puts your tracked tips next to Box 7 and tells you whether the gap is small enough to ignore or big enough to bring to payroll before you file.
How it’s calculated
- Net tracked tips. Take your tracked tip total and subtract the tip-out you paid out. That’s the apples-to-apples number to compare against Box 7.
- Difference vs. Box 7. Subtract Box 7 from net tracked tips.
- Positive (tracked > Box 7): your employer reported less than you tracked. That’s an undercount.
- Negative (Box 7 > tracked): your employer reported more. Cash tips, pooled tips, or reclassified tips usually explain this.
- Zero: your records line up. File and move on.
- Box 1 sanity check. Box 1 (“wages, tips, other compensation”) should be at least as large as your net tracked tips. If it’s smaller, something on the W-2 is wrong.
Worked example
A server’s records show $28,500 in tips with $3,000 in tip-out. The W-2 shows Box 7 = $22,000.
- Net tracked: 28,500 − 3,000 = $25,500
- Difference: 25,500 − 22,000 = +$3,500
- That’s a 15.9% undercount
A 1–3% gap is usually rounding or a single missed cash shift. A 15.9% gap is worth a payroll conversation — the missing $3,500 is real income that should have been reported and would also bump up the No Tax on Tips deduction calculation.
Common mistakes
- Comparing gross tracked tips to Box 7. Box 7 reflects what your employer was told about, which is usually net of tip-out. Use net on both sides.
- Treating Box 1 and Box 7 as redundant. They’re different things. Box 1 includes wages + reported tips; Box 7 is just the Social Security tips line. The two won’t match exactly.
- Assuming the gap means fraud. It usually doesn’t. Cash tips that never made it onto a tip-declaration screen explain most of the small gaps. The bigger ones almost always come from pooled-tip arithmetic or a payroll reclassification mid-year.
- Skipping Form 4137 when you should file it. If a meaningful gap remains after talking to payroll, the IRS expects unreported tips on Form 4137. A tax pro can confirm.
Glossary
- Box 7 — “Social security tips” on Form W-2. Tips your employer reported for FICA.
- Box 1 — “Wages, tips, other compensation.” Includes wages plus reported tips.
- Form 4137 — IRS form for reporting unreported tip income, used when your records exceed what’s on the W-2.
- FICA — Social Security + Medicare payroll tax. Applies to all tip income, even after the No Tax on Tips deduction.
- Contemporaneous record — IRS-speak for “you wrote it down at the time, not later.” A daily tip log is the standard.
