Paying Back a Signing Bonus: Signing Bonus Payback, Clawback and Sign On Bonus Repayment Calculator
You have a better offer and one problem: the sign-on bonus from your current job is still inside its clawback period. The agreement says you owe it back if you leave. What it does not say is that the repayment and the tax on it follow different rules, and the gap between them decides how much you should ask the new employer to cover.

Direct answer
If you leave before the commitment period ends, you usually repay the gross bonus, not what landed in your account. Repaid in the same calendar year, the employer takes it off your W-2 and every tax unwinds. Repaid in a later year, you get Social Security and Medicare back, but federal income tax only if the repayment is over 3,000 dollars (IRS Publication 525). Price that true cost, then ask the new employer for a sign-on bonus that covers it. This is coaching, not tax or legal advice.
Run the numbers
Price the clawback, then price the ask.
Enter the sign-on bonus you were paid, the commitment period, how many months you will have worked when you leave, and whether the agreement is prorated or a full clawback. The calculator works out what you owe, how much of the tax on it comes back and when, what leaving really costs you, and the sign-on bonus your new employer has to pay so the move costs you nothing.

Prorated means you owe the unearned months only. Full clawback means any exit before the end of the commitment returns the whole bonus. Your offer letter or bonus agreement says which one you signed.
What leaving now really costs you
Ask the new employer for a sign-on bonus of to cover it after tax.
- You owe back (gross)
- What you actually kept of that slice
- Social Security and Medicare you get back
- Federal income tax you get back
- State tax you get back
- True cost of leaving
Tax treatment from IRS Publication 525 (Repayments): a repayment of 3,000 dollars or less in a later year is not deductible; above 3,000 dollars you may deduct it or claim a credit, and repaid Social Security and Medicare come back through your employer or Form 843. Brackets from Rev. Proc. 2025-32, same income assumed in both years. State treatment of a later-year repayment varies, so it is shown as not recovered. This is career coaching, not tax or legal advice.
The problem
The recruiter at the new company asks if anything is holding you back. You mention the 20,000 dollar sign-on bonus you would have to return and they say "we can probably help with that." Then the offer arrives with a 10,000 dollar sign-on, you do the math on a napkin, and you still cannot tell whether you are ahead, because nobody has told you what the repayment actually costs you after the tax you already paid on it.
How Counteroffer handles it
Paste the new offer and the repayment clause from your current agreement, and Counteroffer works out exactly what you owe, what comes back and when, and the sign-on bonus that makes the switch free. Then it writes the counter: the figure, the one sentence that justifies it (a documented buyout, not a wish), the fallback if the recruiter says the sign-on is capped, and the email. Members get the full package for every negotiation on their plan.
The numbers
What paying back a sign-on bonus really costs, and what to ask the new employer for.
Every row is generated by the same formula the calculator runs, for a single filer earning 120,000 dollars a year in a state with no income tax, with the same income assumed in the year the bonus was paid and the year it is repaid. "Tax you get back" is Social Security and Medicare in every row, plus federal income tax where the repayment is in the same calendar year or is over 3,000 dollars. Figures are rounded to the nearest 10 dollars.
| Situation | You owe back (gross) | What you kept of it | Tax you get back | True cost of leaving | Sign-on to ask the new employer for |
|---|---|---|---|---|---|
| $3,000 bonus, full clawback, repaid in the same calendar year | $3,000 | $2,110 | $910 | $2,090 | $3,000 |
| $3,000 bonus, full clawback, repaid the following January | $3,000 | $2,110 | $230 | $2,770 | $4,000 |
| $10,000 bonus, 12-month prorated, leave at month 9, repaid next year | $2,500 | $1,760 | $190 | $2,310 | $3,330 |
| $10,000 bonus, 12-month prorated, leave at month 9, repaid same year | $2,500 | $1,760 | $790 | $1,710 | $2,450 |
| $10,000 bonus, full clawback, leave at month 9 | $10,000 | $7,040 | $3,130 | $6,870 | $10,000 |
| $20,000 bonus, 24-month prorated, leave at month 10 | $11,670 | $8,210 | $3,690 | $7,970 | $11,610 |
| $25,000 bonus, full clawback, leave at month 4 | $25,000 | $17,590 | $7,880 | $17,120 | $25,000 |
| $50,000 bonus, 24-month prorated, leave at month 6 | $37,500 | $26,380 | $11,870 | $25,630 | $37,450 |
Two patterns fall out of the table. Above 3,000 dollars, the sign-on that covers you is almost exactly the gross you owe, because the tax you recover on the repayment roughly matches the tax you will pay on the new bonus. At 3,000 dollars or less repaid in a later year, the IRS gives no deduction, so the new employer has to pay about a third more than you owe, and the cheapest fix is to settle the repayment before December 31 of the year the bonus was paid.
The stat everyone quotes
"I only have to pay back what I actually received after taxes."
Most repayment agreements say you return the bonus, and the bonus is the gross figure. Whether you ever see the withheld tax again depends on the calendar year of the repayment and on whether it is over 3,000 dollars.
When a 20,000 dollar sign-on bonus is paid, the employer withholds federal income tax (usually the flat 22 percent supplemental rate), Social Security, Medicare and any state tax, and sends it to the government on your behalf. About 14,000 dollars reaches your account. If you leave early, the agreement asks for the bonus back, and the employer cannot return the tax it already paid over for you in a prior year, so it asks for the gross.
In the same calendar year the problem mostly disappears. The employer reverses the wages on this year's W-2, and some payroll teams simply accept the net amount. Either way, by the time you file you are back where you would have been if the bonus had never been paid, and the repayment costs you only what you actually kept.
In a later year the rules split. Social Security and Medicare on the repaid wages come back through the old employer, or through Form 843 if the employer will not refund them. Federal income tax comes back only through your own return, and IRS Publication 525 is blunt about the threshold: since 2018 a repayment of 3,000 dollars or less is not deductible at all. Above 3,000 dollars you can deduct it or take a credit for the tax the bonus caused, whichever saves more. That credit is why the 3,000 dollar line matters so much to anyone leaving in January.
How to do it
How to handle paying back a signing bonus when you take a new job.
Find the exact repayment clause
Pull the offer letter and any separate bonus or repayment agreement and read four things: the commitment period, whether repayment is prorated or all-or-nothing, the trigger (resignation only, or any separation), and the deadline to repay. Many agreements say repayment is due within 30 days of your last day or is deducted from the final paycheck, and that timing decides which tax year the repayment lands in.
Check whether the clause is still enforceable
State law matters here. In California, repayment terms in agreements signed on or after January 1, 2026 must sit in a separate agreement, give you at least five business days to consult a lawyer, be prorated over a retention period of no more than two years with no interest, and let you defer the bonus to the end of that period (Labor Code 926 and Business and Professions Code 16608); you owe nothing if you are let go without misconduct. New York's Trapped at Work Act is scheduled to take effect in 2027. Everywhere else, the contract usually governs.
Work out the true cost, not the headline
Run the calculator above. The figure that matters is not what you owe, it is what you owe minus the tax you get back, and when you get it back. On a 20,000 dollar bonus, 24 months prorated, leaving at month 10, you hand back 11,670 dollars but the true cost is about 7,970 once the payroll tax and the claim-of-right credit return.
Move the repayment into the right calendar year if you can
If you owe 3,000 dollars or less and you are leaving late in the year, settling the repayment before December 31 of the year the bonus was paid recovers the income tax that a January repayment would lose for good. If the bonus was paid this year and you are leaving this year, you are already in the best case: ask the old employer to reverse it through payroll rather than invoice you.
Ask the new employer to buy out the clawback
A clawback is one of the easiest sign-on bonus requests to win, because it is a documented cost the recruiter can put in front of the approver, not a wish. Ask for the figure from the calculator, not a round number, and offer to share the repayment clause. The sign-on bonus negotiation page covers the general wording, and the sign-on bonus negotiation email has templates you can adapt.
Make sure the new bonus does not recreate the problem
The new sign-on will almost always carry its own repayment clause. Ask for it to be prorated monthly rather than all-or-nothing, for the commitment to be 12 months rather than 24, and for no repayment if you are let go without cause. Asking for the buyout to be paid on your first paycheck, not after 90 days, closes the cash gap between repaying the old employer and receiving the new money.
Compare the whole move, not just the bonus
A buyout that covers the clawback only brings you back to even. The decision is still the new base, bonus target, equity and benefits against the old ones. The job offer comparison calculator puts both packages side by side after tax, and the bonus tax calculator shows what the new sign-on will actually land as on payday.
Get the buyout in the offer letter
The sign-on amount, when it is paid, its own repayment terms and any promise to cover the old clawback belong in the written offer before you resign. A verbal "we will take care of it" is not a number and does not survive a change of recruiter.

The reply that asks the new employer to cover your sign-on bonus repayment.
Send this once you have a written offer and before you resign. It works because it turns the ask into a documented cost with a specific figure, which a recruiter can approve far more easily than an open-ended request for more money. Replace the bracketed parts with your figures from the calculator.
Subject: Re: Offer for [role] Hi [name], Thank you for the offer. I am excited about the role and I want to make this work. There is one cost I need to solve before I can resign. My current employer paid me a sign-on bonus of [amount] with a [commitment] month repayment clause, and leaving now means repaying [amount owed]. After the tax I recover, the move costs me about [true cost], and a sign-on bonus of [ask] covers that after tax on your side. I am happy to share the repayment clause. Could the offer include a sign-on bonus of [ask], paid with my first paycheck, with repayment prorated monthly over 12 months? With that in place I can give notice this week. Thanks again, [your name]

Frequently asked
Questions people ask about paying back a signing bonus.
Do I have to pay back my signing bonus if I quit?
Usually yes, if you signed a repayment agreement and leave before the commitment period ends. The agreement sets how much: either the full bonus or a prorated share for the months you did not work. In California, agreements signed since January 1, 2026 must be prorated over no more than two years and carry no interest.
Do you pay back the gross or net sign-on bonus?
Most agreements require the gross bonus, the figure before withholding. If you repay in the same calendar year, the employer reverses the wages on your W-2, and some accept the net amount, so the tax unwinds either way. In a later year you repay the gross and recover the tax through your employer and your own return.
Can I get taxes back if I repay a signing bonus?
Partly, and it depends on timing. Social Security and Medicare on the repaid amount come back through your old employer or Form 843. Federal income tax comes back automatically in the same calendar year, but in a later year only if the repayment is over 3,000 dollars, by deduction or a claim-of-right credit on your return (IRS Publication 525).
Is a sign-on bonus repayment tax deductible?
Only above 3,000 dollars when it is repaid in a later year. IRS Publication 525 says that for tax years after 2017 a repayment of 3,000 dollars or less is not deductible at all. Above 3,000 dollars you can take it as an itemized deduction or claim a credit for the tax the bonus caused, whichever gives the lower tax.
Will my new employer pay back my sign-on bonus?
Often, if you ask with a specific figure. Covering a clawback is a common reason for a sign-on bonus, and a documented cost is easier to approve than a general request for more. Ask for the amount that covers your true cost after tax, not just the gross you owe, and get it in the offer letter before you resign.
How is sign-on bonus repayment calculated?
A prorated agreement divides the bonus by the months in the commitment period and charges you for the months you did not work: a 24,000 dollar bonus over 24 months, leaving at month 10, means 14,000 dollars owed. An all-or-nothing clause returns the whole bonus for any early exit. The calculator above supports both.
Do you have to pay back a sign-on bonus if you get fired?
It depends on the agreement and the state. Many agreements only require repayment if you resign or are fired for cause. In California, agreements signed since 2026 cannot require repayment if you are terminated without misconduct, and New York's Trapped at Work Act, scheduled for 2027, allows bonus repayment only after a termination for misconduct.
What happens if you don't pay back a sign-on bonus?
The employer can pursue it as a debt, which usually means collection letters and, for larger amounts, a lawsuit or small claims case. Many employers first try to deduct it from the final paycheck, which some states restrict. Negotiating a payment plan or asking the new employer to cover it is almost always cheaper than ignoring it.
Is a signing bonus clawback enforceable?
In most states a clearly written clawback in an agreement you signed is enforceable as a contract. California now limits them for agreements signed on or after January 1, 2026, and New York's law is scheduled for 2027. If the clause is unclear or was never signed, it is worth having an employment lawyer read it before you repay.
