A retention bonus is one of the simplest tools in a business sale: pay a key employee extra to stay through a defined point, instead of leaving them to wonder whether it’s worth sticking around. Straightforward in concept, but there are a number of moving parts worth understanding before you promise one.
This article looks specifically at how retention bonuses are typically timed, conditioned, and paid in an Ontario business sale — separate from the broader retention agreement that usually surrounds them.
What a Retention Bonus Is (and Isn’t)
A retention bonus is additional compensation, on top of an employee’s regular pay, conditioned on staying employed through a defined date or milestone — commonly closing, sometimes a period beyond it. It is not the same as a signing bonus, a severance payment, or a performance bonus, though the paperwork can blur those lines if it isn’t drafted carefully.
How They’re Typically Sized
There’s no standard formula, percentage, or typical dollar range for a retention bonus — it’s negotiated based on the employee’s importance to the deal, how difficult they’d be to replace, how long they need to stay, and what the buyer and seller are willing to put toward it. Any number you’ve seen quoted as a "typical" retention bonus reflects someone else’s deal, not a benchmark for yours — this is a negotiation, not a formula, and needs to be worked out with your lawyer and accountant for your specific transaction.
How They’re Timed and Triggered
Retention bonuses are usually tied to one or more of:
- Signing of the definitive purchase agreement
- Closing of the transaction
- A period after closing — often when the buyer wants continuity through an integration period
They can be paid as a single lump sum at the trigger date, or split into installments — for example, a portion at closing and the remainder after a further stay-through period.
Common Conditions Attached
Most retention bonus arrangements condition payment on:
- [ ] Continued active employment through the specified date (no earlier resignation or termination for cause).
- [ ] The transaction actually closing — if the deal falls apart, the agreement should say clearly whether any bonus is still owed.
- [ ] No material performance or conduct issues in the interim.
- [ ] Continued confidentiality about the pending sale, where relevant.
Clawbacks and Forfeiture
Well-drafted retention agreements often include a clawback or forfeiture provision — for example, requiring repayment if the employee resigns shortly after receiving the payment. Whether this is appropriate, and how it’s worded, depends on the role and the deal.
Who Pays: Buyer or Seller
| Scenario | Typical approach |
|---|---|
| Seller wants to reduce deal risk before closing | Seller funds the bonus, often treating it as a transaction cost |
| Buyer specifically wants the employee retained post-closing | Buyer funds the bonus, sometimes reflected in post-closing purchase price mechanics |
| Shared priority for both sides | Cost is split or factored into the negotiated purchase price |
There’s no default rule — the purchase agreement needs to say explicitly who is responsible for the payment and when.
Tax and Documentation
Retention bonuses are generally treated as employment income and are subject to standard payroll withholding, though the exact tax treatment can depend on how the payment is structured. This is an area to work through with your accountant alongside your lawyer — don’t assume a retention bonus is taxed the same way as, say, a capital gain on a share sale.
A Single Bonus vs. a Broader Retention Pool
Some sales involve one retention bonus for a single indispensable employee. Others involve a small pool spread across several people whose collective departure would be disruptive even if no individual is irreplaceable. The legal mechanics are similar either way — each person needs their own clearly documented agreement setting out the amount, timing, and conditions that apply to them — but a pool arrangement usually calls for more careful coordination so employees aren’t comparing notes on inconsistent terms partway through the process.
Frequently asked questions
Is a retention bonus the same as severance?
No. Severance is paid when employment ends; a retention bonus is paid, or promised, specifically to keep someone employed through a defined point. Confusing the two in drafting can create real problems if the employment relationship later ends.
What happens if the deal doesn’t close?
This should be addressed explicitly in the retention agreement. Some agreements pay nothing if the transaction doesn’t close; others treat certain payments as earned regardless. There’s no default answer — it depends on what was negotiated.
Can a retention bonus be paid in installments?
Yes, this is common, particularly where the buyer wants continuity past closing. The agreement should specify each trigger date and condition clearly.
Do all key employees need a written retention agreement to get a bonus?
It’s strongly advisable. An informal promise of a bonus is much harder to enforce, and much easier to dispute later, than a properly documented agreement.
