Vendor take-back vs earn-out

Both a vendor take-back and an earn-out push part of a sale price past closing day, and buyers and sellers often use the terms loosely, as if they were two flavours of the same thing. They are not. A vendor take-back is the seller agreeing on a number today and accepting payment for it later. An earn-out is buyer and seller declining to agree on a number today at all, and letting the business itself settle the argument over the following months or years. That difference in kind — a fixed debt versus a contingent right — is what drives everything else that differs between them: how each is secured, how each is documented, and how each is taxed.

Vendor take-back: a fixed, deferred purchase price

A vendor take-back sets the full purchase price at closing, the same as if the buyer had paid entirely in cash, and simply lets the buyer pay part of that already-agreed number over time under a promissory note. The seller knows the total dollar amount owed on day one; what remains open is only the repayment schedule and what happens if a payment is missed. Because the amount is fixed and known, a vendor take-back behaves like ordinary debt from the seller’s point of view: it can be secured with a registered interest, assigned an interest rate, and amortized on a defined schedule, exactly as a bank loan would be.

• The dollar amount owed is fixed at closing; only the timing of payment is deferred
• Typically documented in a standalone promissory note, separate from the purchase agreement itself
• Commonly secured by a registered interest in the business’s assets or shares, ranking behind any bank debt
• A missed payment is a default under the note, giving the seller creditor-style remedies, not a valuation argument

Earn-out: contingent consideration tied to future results

An earn-out does not set a fixed number at closing at all — it sets a formula, usually tied to revenue or earnings over a defined period after the buyer takes over, and pays the seller only if and to the extent the business meets it. Nothing is owed if the formula is never met, which is the entire point: an earn-out exists because the buyer and seller genuinely disagree about what the business will do next, and neither side is willing to simply accept the other’s number. That uncertainty carries through to how the right is documented and protected. Because there is no fixed sum, an earn-out is rarely secured the way a promissory note is; instead, the seller’s protection usually comes from operating covenants written into the purchase agreement — restrictions on how the buyer may run the business during the earn-out period, reporting obligations so the seller can see the numbers being measured, and sometimes audit rights if the parties end up disputing the calculation.

• The amount owed is unknown at closing and depends entirely on a formula applied to future performance
• Documented as a detailed schedule in the purchase agreement itself, covering the metric, the measurement period and how disputes over the calculation get resolved
• Protected mainly through operating covenants and reporting rights rather than registered security, since there is no fixed sum to secure
• The most heavily negotiated and most frequently disputed mechanism in Canadian small business deals, because the metric and the seller’s influence over it are rarely defined precisely enough at the outset

How each is taxed, in principle

The tax treatment tracks the same fixed-versus-contingent divide. Because a vendor take-back is repayment of an already-agreed price, Canadian tax rules generally allow a seller to recognize the resulting capital gain gradually as the note is actually paid, rather than all at once in the year of sale, through a reserve mechanism built for exactly this situation — deferred but certain proceeds. An earn-out sits in much less settled territory. Because the amount is not fixed or even knowable at the time of sale, the CRA’s administrative treatment depends heavily on how the earn-out clause is drafted; in some circumstances a specific administrative approach may let earn-out payments on a share sale be treated similarly to proceeds of the original sale, and in others a poorly drafted earn-out risks being taxed as ordinary income rather than as part of a capital gain. The difference between those two outcomes is large, and it turns on wording decided months before any earn-out payment is ever calculated.

How to choose

These two mechanisms usually get chosen for different reasons rather than compared head-to-head. A vendor take-back tends to be the answer when the buyer simply cannot fund the full price at closing and the seller is comfortable being a creditor for a while, confident enough in the business to accept a fixed IOU rather than cash in hand. An earn-out tends to be the answer when the two sides cannot agree on the price at all — the seller believes recent growth will continue, the buyer is not convinced — and both would rather let the business prove it than fight over a single number now. Many deals use one, the other, or both alongside a bank loan and a buyer down payment, and the priority between a vendor’s registered security and a bank’s security, where a take-back is used, needs to be documented in an intercreditor arrangement rather than assumed. Whichever mechanism is on the table, how it is secured, what triggers payment, and how it will be taxed are three separate questions that each need answering before signing, not after.
