The offer lands on a Thursday in early October: a better title, a base salary that finally matches what the market pays, and a start date in early November. Meanwhile, the annual bonus at your current job is built on this calendar year, calculated after the books close and typically paid out early next year. The new offer says nothing about it, and you are about to resign from a job where that money still exists only in the future tense. Whether you keep it after you leave depends on two short pieces of paperwork that almost nobody reads before sending the resignation email. One is the sentence in your bonus plan that says who qualifies, and the other is the sentence in your new offer that says what happens to a sign-on bonus if you leave early. October is the right month to find both, because offers, bonus calculations and year-end paperwork all arrive in the same quarter.
The Sentence That Decides Who Gets Paid
In many states, the plan document gets the final word.
Start by finding it, because the number your manager mentioned in a one-on-one is not the document. Look in the HR portal, in the compensation section of the intranet, in your original offer letter, or in the email that announced this year's bonus program, and read the eligibility language slowly. You are looking for phrases like "must be actively employed on the payment date" or "must be employed on the last day of the plan year," and the difference between them is the whole ballgame. The first means the bonus can be fully earned by December 31 and still vanish if you leave before the check is cut in March; the second means your last day only has to fall after the year closes. Lawyers at Troutman Pepper have described the pattern in a survey of state rules: in Georgia, Virginia and New York, among other states, courts will enforce a forfeiture clause when the wording is clear, and New York courts have regularly upheld forfeiture of bonuses when people left before payout. That survey is more than a decade old, so treat it as a map of how the arguments run and check your own state's current rule.
There are limits, and they cut in your favor if the wording is sloppy. Georgia courts, according to the same survey, resolve confusing language in favor of paying the bonus, and New York and California treat earned commissions as wages that cannot be forfeited, which is a different category from a bonus. So if part of your pay is sales commission, ask which bucket each dollar sits in before you assume anything. And a payment-date clause can hold up even if you did every hour of the year's work, because the plan defines what "earned" means.
"Discretionary" Is Doing Less Work Than HR Thinks
Plenty of companies call the year-end bonus discretionary, which sounds like a reason not to bother asking about it. The U.S. Department of Labor's guidance, which is written for overtime calculations and not for payout disputes, says a bonus is discretionary only if the employer keeps sole control over whether to pay it and how much until close to the end of the period, and does not pay it under a prior promise that makes employees expect it regularly. The same fact sheet says the label an employer attaches does not settle the question. That definition will not win you a claim on its own, but it is a useful test of how much of a promise your bonus really is: a published target, a formula and a payout chart read like something offered, while a lump sum nobody described until December reads like a gift.
What to Do Before You Hand In Notice
Ask HR, in writing, a question that does not announce your plans. Something like "I'm planning my year-end finances and want to confirm the eligibility rule and expected payment date for the annual bonus" gets you an answer you can screenshot, and it sounds like a thing a careful employee asks every October. Keep the HR reply and your own bonus statements from past years, which are records of your pay, and check what your employer's policy allows before you copy anything else.
Then compare your last day with the payment date, and treat any gap as a negotiating point rather than a loss. Ask the new employer for a start date after the payout date; if they genuinely need you in November, ask instead for a sign-on bonus sized to the bonus you are leaving behind, and attach last year's statement to show the number. Both requests are reasonable, and the worst realistic answer is no. Do it before you accept, because once you sign, you have nothing left to bargain with.
This is general information, not legal advice. If the bonus is a large share of your yearly pay, an hour with an employment lawyer in your state is worth booking before you resign.
The Second Clause: Your New Sign-On Bonus Might Come With a String
A sign-on bonus often arrives with a repayment agreement, and the questions that matter fit on an index card. How long is the retention period, and does the repayment shrink month by month or stay all-or-nothing until the date passes? Do you owe the gross amount or only what you actually received after withholding? What happens if the company lets you go, and is the agreement a separate document or a paragraph buried in the offer letter?
The gross-versus-net question has a tax side. If you do end up repaying income you were already taxed on in an earlier year, IRS Publication 525 allows either a deduction or a credit for repayments over $3,000 under the claim-of-right rules, and says repayments of $3,000 or less can no longer be deducted. A tax preparer can tell you how that plays out in your situation, but you should know the threshold before you agree to a clause that could put you above it.
The Rules on These Clauses Are Moving Right Now
Federal regulators tried to restrict these arrangements: a 2024 Federal Trade Commission rule treated training repayment agreements as functional noncompetes. A federal district court struck the rule down and the FTC withdrew its appeal, which left the work to the states. According to a summary from the Connecticut firm Pullman & Comley, reposted by the state business association CBIA in July, Connecticut's expanded law took effect on October 1, 2026. It covers all employers and voids repayment obligations tied to leaving before a stated period, whether the payment is called training reimbursement, a retention payment or a sign-on bonus, with exceptions for things like advances and property sold to the employee.
New York's Trapped at Work Act, signed on December 19, 2025 and amended in February, is expected to take effect on December 19, 2026, though the same summary notes some practitioners read the date as February 13, 2027. As amended, it still allows an employer to require repayment of a bonus or relocation payment unless the employee is terminated for reasons other than misconduct or the job duties were misrepresented. California's law, AB 692, lets employers keep a repayable bonus only under conditions that include a separate agreement, at least five business days to consult a lawyer, no interest, prorated repayment and a retention period of no more than two years. Morgan Lewis reported on October 1 that an amendment, AB 1697, now applies those rules to contracts signed on or after January 1, 2027.
Read those dates as a warning that the answer depends on where you work and the day you sign. Check which state's rules your employer says apply, especially if you work remotely, and ask for the repayment terms in a separate document with time to review it.
Two Other Dates That Can Cost You More Than a Bonus
Your own 401(k) contributions are always 100 percent yours, but the employer match can follow a vesting schedule. Federal rules cap a cliff schedule at three years and a graded schedule at six, per IRS guidance on matching contributions, so a resignation a few weeks before an anniversary can leave real money behind. Look at the vested percentage on your latest plan statement and note the next date it steps up.
Equity works the same way, with the details in your grant agreement. Unvested shares are usually forfeited when you leave, and some companies vest quarterly, so a two-week delay in your last day can be worth more than any negotiation over base salary. Pull up the vesting schedule in your equity portal this week, while you are still deciding.
Put three dates in one row of a spreadsheet: the bonus payment date, the next vesting date for your match or equity, and the first day your new employer needs you. If the third date lands before the first two, you have a decision to make, and at least you will be making it with the real numbers. If it lands after them, you are not giving up any of the three, and the only thing left is to send the resignation email.
