You paid tax on a bonus, then repaid it to your employer in a later year. Your employer cannot change box 1 wages or income tax withheld on last year's W-2, so you claim the income tax back on your own return. Dimov Tax files the claim that saves you more.

You claim nothing extra when you repay in the same year, because your employer takes the repaid amount off your W-2 wages and withholding.
You get no federal income tax back on a later year repayment of $3,000 or less, because the IRS allows no deduction for it after 2017.
Over $3,000 in a later year, you choose an itemized deduction or the claim of right credit, a credit for the extra tax you paid on the bonus.
When you repay in the same year, your employer recovers the tax withheld on the repaid amount through its payroll filings. Your employer then issues a W-2 without that amount.
Check the W-2 before you file. If it still shows the bonus, ask your employer to correct it first.
Your employer leaves the bonus in box 1, the wages subject to income tax, on the earlier year's W-2. Under IRS Publication 15, an employer cannot correct box 1 or the income tax withheld for a prior year.
For a bonus repayment in subsequent year, you recover the income tax on your own return for the year you pay the money back. You cannot amend the earlier year's return to recover it.
Check your repayment agreement before you pay. If the agreement sets the repayment at the gross bonus, the amount before withholding, you repay more than you took home. Over $3,000, the deduction or credit is how you recover tax on it.
Above $3,000, the claim of right doctrine applies. The IRS treats the bonus as a claim of right repayment if you appeared to have an unrestricted right to it when you received it. You choose one of two methods:
Claim of right deduction. You deduct the repaid amount on Schedule A, line 16, as an other itemized deduction. You save tax at this year's rate, and you need to itemize to use it.
Section 1341 credit, the claim of right credit. We refigure the earlier year's tax without the bonus, and you claim the drop in that tax as a credit on Schedule 3, line 13b. If the credit is larger than this year's tax, you receive the excess as a refund.
The credit does not require itemizing, so a filer on the standard deduction can still recover the tax.
The IRS has you figure the tax both ways and use the method that leaves less tax. The credit saves more when you paid more tax on the bonus than the deduction saves now.
You received a $25,000 signing bonus in 2025, left before your tenure date, and repaid the full $25,000 in 2026.
We assume a single filer, federal tax only, a 32% rate on the full 2025 bonus, a 24% rate on the 2026 deduction, and itemized deductions above the standard deduction.
| 2026 return | Deduction | Credit |
|---|---|---|
| Tax rate used | 24%, the 2026 bracket | 32%, the 2025 bracket |
| Tax saved | $6,000 | $8,000 |
You save $2,000 more with the credit. With the two brackets reversed, you save more with the deduction.
Send us the earlier year's return and your repayment letter, and we show you the tax saved before anything is filed.
Ask your employer to refund any excess Social Security and Medicare tax on a bonus you repaid in a later year. Your employer corrects those wages on Form W-2c, a corrected W-2.
If your employer refuses, get a written statement of the amount overcollected and file Form 843 with the IRS.
To recover Additional Medicare Tax, the extra Medicare tax charged on higher wages, you file Form 1040-X for the year you received the bonus.
We request the W-2c from payroll and prepare Form 843 when an employer does not refund.
Each state sets its own rules for sign on bonus repayment taxes. California, under its Schedule CA (540) instructions:
We check the state that taxed the bonus and the state where you live now, then claim what each allows.
We work out the bonus repayment tax treatment from three facts: the year you repay, the total repaid and how the original payment was reported.
Leaving before the tenure date means paying back a sign on bonus. If you repay in a later year, we claim the tax on that year's return.
We handle it like a signing bonus repayment when you leave before the retention period ends.
We treat a chargeback like repaid wages, or deduct it on Schedule C if you were paid as a contractor.
If your employer reported the payment on your W-2, we treat it like any repaid wages.
If your agreement covers more than one of these, send it to us before you repay and we will tell you how each part is taxed.
Read the agreement. We check the repayment terms, the dates and the amount you paid back, gross or net.
Rebuild the earlier year. We refigure the year you received the bonus without it, starting from the return you filed.
Run both methods. We calculate the deduction and the section 1341 credit, federal and state, and show you the result.
File the claim. We claim the result on your return with a statement of the year, the amount and the calculation.
If you claim too large a credit, the IRS adjusts the return and bills you. Claim too little and you leave tax with the IRS.
You can book the first call before you gather these.
We quote a fixed fee for a bonus repayment in subsequent year claim before we start, based on:
The light end is one repayment over $3,000, one state, and an earlier year return we can work from. These are the factors, not a quote.
Speedy, friendly service with a more complex return with corporate stocks and bonuses in foreign currencies.
You claim tax back on a bonus repayment in subsequent year on the return for that year, so a 2026 repayment goes on the return you file in 2027. Call now and we will tell you which method to use.
A CPA or Enrolled Agent handles your claim in confidence. Or call (866) 681-2140.
