Retention Bonuses and Counteroffers: Do They Work?

A retention bonus is a one-off payment an employer promises if you stay until a set date, often with a clawback that makes you repay it if you leave before then. A counteroffer is the raise or promotion offered after you announce you are going. The best evidence comes from teachers: in an English scheme that began paying in 2019/20, eligible teachers were 23 percent less likely to leave in the years they qualified for extra pay.¹ Evidence from mergers and recruiter surveys suggests the effect tends to end when the reason for paying ends.

Whether one is worth offering or accepting depends on why the person wants to go. Money fits a pay gap or a fixed deadline, such as the months until a merger closes. When the reason is the manager, the workload or a stalled career, a payment mostly moves the resignation date later. For employers it is one tool among many for employee engagement and company culture.

What is a retention bonus?

A retention bonus is extra pay conditional on staying through a defined period, such as a merger, a product launch or a hard-to-fill stretch. In WorldatWork’s 2014 survey of its mostly North American members, a single lump sum was the most common form, used by roughly two-thirds of organizations, and a flat dollar amount was the most common way to set its size.²

The structure matters because the money only holds people while it is still unpaid. A single payment at the end gives a strong reason to stay up to the payout date and none after it. Payments spread over the period keep the incentive alive for longer but make each step smaller.

A software company might promise the two engineers who know its old billing system a sum payable on the switch-over date. A job offer a month before meets an unpaid reason to wait; the morning after the payout, that reason has gone.

An annual bonus works differently. A recruiter quoted in a 2023 SHRM article argued that employees see a year-end bonus as already earned, so it does little to hold them once paid.³ The view is untested. If you are offered a retention bonus, get the payout date and the repayment terms in writing before you plan around the money.

How is a retention bonus taxed?

US and UK tax rules treat a retention bonus as ordinary employment income. The IRS lists bonuses among supplemental wages in Publication 15 for 2026: an employer may withhold federal income tax at a flat 22 percent, or at 37 percent on supplemental wages above $1 million in a calendar year, and the bonus is also subject to social security and Medicare taxes.⁴ IRS Publication 525 confirms that bonuses are included in your income and shown on your Form W-2.⁵

HMRC’s employer guidance (as of 2026) lists bonuses among the payments to employees from which a UK employer deducts tax and National Insurance through PAYE.⁶ Elsewhere, assume a bonus is taxed as pay unless your own tax authority says otherwise, and check its guidance for how and when tax is withheld.

Do you owe a retention bonus back if you quit early?

That depends on the agreement you signed and on local law. A clawback clause makes you repay the bonus, in full or in part, if you leave before the date. Read three things before signing: what counts as leaving, whether repayment is full or reduced for time served, and how the employer would recover the money.

Under a twelve-month agreement that reduces repayment for time served, someone who leaves after eight months would owe back a third; under an all-or-nothing clause, they would owe the whole sum.

Recovery depends on local law. UK government guidance on pay (as of 2026) says an employer may deduct from pay only in listed cases, such as when the law requires it, your contract allows it or you have agreed in writing, and a deduction normally cannot take pay below the National Minimum Wage unless it is for one of a few listed reasons, such as repaying a loan or advance of wages.⁷

Repaying also has a tax side. In the US, IRS Publication 525 (2025 edition) says that if you repay wages you were taxed on in an earlier year, you can deduct the repayment or take a credit only if it is over $3,000, and that you should ask your employer to refund social security and Medicare tax paid on the repaid wages.⁵ Readers in other countries should ask their tax authority how a repaid bonus is treated.

Do retention bonuses keep people? The teacher studies

The strongest studies of retention bonuses come from public schools, where governments pay teachers to stay in shortage subjects or struggling schools. Targeted money kept some people for the period it covered, with effects that depended on who was eligible and whether people understood the offer in time.

The study

Limited evidence

Did a US$5,000 stay bonus keep top teachers in Tennessee's struggling schools?

Springer, Swain and Rodriguez (2016) studied a Tennessee program that offered US$5,000 to teachers rated highly effective who stayed in its Priority Schools for the 2013–14 school year; 361 teachers received one. The researchers compared teachers just above and just below the rating cut-off. Overall, they found no clear effect on retention. For teachers of tested subjects and grades, recipients were about 20 percentage points more likely to stay than similar teachers just below the cut-off, by the authors’ main estimate.⁸

The authors suspect a stronger push the other way: the state’s evaluation system tied much of untested-subject teachers’ ratings to school performance, which gave them a reason to leave low-performing schools. The program was also announced in March, after many teachers had made plans, and some principals did not follow the eligibility rules. The study was funded through Tennessee’s federal Race to the Top grant.

The English scheme gave early-career maths and physics teachers in 42 disadvantaged local authority areas £2,000 a year after tax, about 8 percent of minimum gross teacher pay. The authors, funded by the Gatsby Foundation, estimate the policy cost about a third less per extra teacher retained than training a replacement. Their design is quasi-experimentalquasi-experimental: Describes a study that compares a group that got something with a group that did not, where the researcher did not do the assigning: a policy, a rollout or people's own choices did. Because the groups were not formed at random, they may have differed before it started.Full entry in the glossary, comparing eligible teachers with similar ineligible ones across years, regions and subjects, and it appeared as a working paper, without peer review.¹ Springer and colleagues also describe a North Carolina bonus of US$1,800 a year from 2001 to 2004 that was linked to about 17 percent lower turnover among eligible teachers, though surveys found many teachers misunderstood it.⁸

A randomized test outside schools found no clear added effect from the condition itself. In a 2018 pilot field experimentfield experiment: An experiment run in a real setting, such as a workplace, shop or website, with people going about their ordinary lives, usually with random assignment. It shows how an effect plays out in practice, though often for one setting and one group at a time.Full entry in the glossary with 188 new hires at an Ethiopian garment factory, workers promised a bonus worth about a month’s wage for staying three months were no more likely to stay than workers promised the same sum regardless. The authors note the pilot was small and suggest low wages were the main reason for the factory’s high turnover.⁹

A 2020 systematic review of 20 research reports on hard-to-staff schools, by See and colleagues, was less hopeful about money as a retention tool. It found financial incentives helped attract teachers to challenging schools but did not appear to keep them there, and pointed to a supportive working environment instead.¹⁰

In mergers, retention pay delays departures

Mergers and acquisitions are a common setting for retention bonuses, and the evidence there suggests they delay departures more than they prevent them. In the Towers Watson 2014 Global M&A Retention Survey, which covered companies in 14 countries, 68 percent of respondents said more than four in five employees asked to sign a retention agreement stayed for the full period. A year after the period ended, only 43 percent still kept that rate. Concern about changes in organizational culture was the main reason people left before the period ended.¹¹

1. The agreement period: most people who signed a retention agreement stay, and leaving early would cost them the payment
2. The payout date: the money is paid and the reason to stay that it created ends
3. The year after: fewer companies keep the same share of those people a year later

A schematic shape, not plotted from data. Upward is the share of people still in their jobs; rightward is time.

A peer-reviewed survey of 406 employees at Hong Kong banks, some bought by Chinese state-owned banks between 2004 and 2008, reports that a retention bonus delayed departure after the merger. Leavers from the acquired banks were also more likely than employees of non-merged banks to report what the authors call a shock.¹² This article draws only on the abstract of that study, and the abstract gives no length for the delay.

An acquired team that signs one-year agreements may work through the integration and then see several people resign soon after the payout, if the reporting lines they disliked are still there. A longer hold needs the money paired with a fix for what people were worried about.

Do counteroffers actually keep employees?

Counteroffers keep some people for a while, but the evidence is thin and comes almost entirely from recruiting firms, which earn fees when people change jobs. In a nationally weighted December 2021 survey of UK employees for Robert Half, just over half of those who had received a counteroffer accepted it. Of those who accepted, about a third had left within six months and about three-quarters within a year.¹³

A 2023 Robert Walters survey of employees in Japan registered with the firm found a similar short horizon: 38 percent of those who had accepted a counteroffer said they stayed only about six more months.¹⁴ Both rely on memory and neither compares people with similar employees who were never offered one, so they show what happened afterward, not what the counteroffer caused.

Myth

80% of people who accept a counteroffer leave within six months.

Fact

No study behind this figure could be found. Recruiter surveys in the UK and Japan put it at about a third to two-fifths within six months, with more leaving over the following year.

The 80 percent figure circulates on recruitment blogs. Some credit a Wall Street Journal survey, but none of the pages we checked gave a year, a link or a method.

Should you accept a counteroffer?

A counteroffer deserves serious thought when it fixes the reason you started looking. If the reason was pay, a matched salary addresses it. In the Robert Walters survey, a higher salary was the factor most often named by people who would consider a counteroffer.¹⁴ If the reason was your manager, your workload, a lack of growth or the way you are treated, a raise leaves that untouched, and the six-month and one-year figures above show that many people who accept still leave.

Before you answer, write down why you applied elsewhere and check each reason against what the offer changes. Ask what else would change, such as a new role, a different manager or a promotion with a date attached.

When a bonus or counteroffer makes sense for a manager

A retention payment is a reasonable tool when the problem is time-limited or about pay, and a weak one when the person wants to leave because of the job itself. The English scheme targeted teachers whose degrees command higher pay outside teaching.¹

It makes sense when you need someone through a known date, such as the end of an integration, a launch or an audit; when the person is leaving for pay and the market rate for their role has moved; and when you would pay a similar sum anyway to replace them. A rough figure from estimating the cost of turnover for one role helps with that comparison.

It mostly delays the quit when the person’s reasons are their manager, an unmanageable workload, no path to grow, or a culture they distrust. Then a payment buys months to fix the cause, and the retention strategies with the strongest evidence are where that work starts.

Before you offer a retention bonus or counteroffer

• Write down why the person wants to leave, in their words
• Check whether money fixes that reason or only delays it
• Tie any bonus to a specific date or milestone, and announce it before people decide
• Put the amount, date and repayment terms in writing, and have them checked against local law
• Compare the cost with replacing the person
• Plan what will change for the cause before the payout date

When to get professional advice

How a retention bonus is taxed and whether it can be clawed back depend on your country, your contract and your tax position. Before you sign, have an employment lawyer or an independent adviser read any agreement whose repayment terms you do not fully understand.

If an employer asks for a bonus back or deducts it from your final pay, get advice soon. In Great Britain, Acas guidance (updated October 2026) says to raise a disputed deduction informally first, then as a formal grievance, and warns of strict time limits for employment tribunal claims; its helpline answers individual questions.¹⁵ In the US, the Department of Labor lists every state’s labor office.¹⁶ Elsewhere, try your national labour inspectorate, a trade union or an employment lawyer.

At tax time, your tax authority or a qualified tax adviser can confirm how a bonus or a repayment affects your return.

The bottom line

Name the reason for leaving before anyone puts money on the table. Where the gap is pay or a fixed deadline, a retention bonus or counteroffer can hold someone through it. Where the reason is the manager, the workload or growth, use the months the money buys to fix that cause, and read the repayment terms before you sign.
