- An earnout or vendor take-back loan means part of your price arrives after closing, so you carry the buyer's risk until it is paid.
- If part of the price is payable after the end of the tax year, you may be able to claim a capital gains reserve, which spreads the gain over up to five years in total.
- The reserve is not available in every case, including some sellers who are not resident in Canada and some sales to a buyer you control.
Many buyers do not pay the full price on closing day. You may be offered part in cash now and the rest later, either as a fixed loan you lend back to the buyer or as extra payments that depend on how the business performs.
Both can make a deal possible, but both leave you exposed after you have handed over the keys. This article explains how they work in plain terms, the main risks, and how the tax rules on deferred payments generally apply in Ontario.
What an earnout and a vendor take-back loan are
A vendor take-back (VTB) loan means you, the seller, lend the buyer part of the price. The buyer signs a promissory note, usually with an interest rate, a repayment schedule and security over the business assets or shares.
An earnout is different. Part of the price depends on future results, such as revenue or profit over the next one to three years. The final amount is not known on closing day, which is why the contract wording matters so much.
| Feature | VTB loan | Earnout |
|---|---|---|
| Amount owing | Fixed in the note | Depends on future results |
| Main risk | Buyer cannot or will not repay | Dispute over how results are measured |
| Typical protection | Security, guarantees, default terms | Clear definitions, reporting and audit rights |
The risks of being paid over time
Once you are paid in instalments, you become a lender to the buyer. If the business struggles, your payments may be at risk, and you may rank behind a bank that financed the purchase. Whether you can step in depends entirely on what you negotiated.
- Security: whether your note is secured, and whether it ranks ahead of or behind other lenders.
- Control after closing: with an earnout, the buyer runs the business and can make decisions that lower the results used to calculate your payments.
- Definitions: terms such as profit, revenue and adjustments must be spelled out so both sides calculate them the same way.
- Default terms: what happens if a payment is missed, including whether the whole balance becomes due.
- Guarantees: whether the buyer's owners personally back the obligation.
These are drafting and negotiation points. They are worth settling in the agreement before closing, because fixing them afterward is much harder.
How the tax reserve applies to deferred payments
When part of the sale price is payable after the end of the year, you can generally claim a capital gains reserve instead of reporting the whole gain at once. The reserve is the lesser of a reasonable amount for the unpaid proceeds and 1/5 of the gain multiplied by (4 minus the number of preceding years ending after the sale).
In practice, at least 1/5 of the gain is taxed each year, and the whole gain is taxed within five years. The CRA describes this as a reserve period of up to four years, so the gain is included in income over five years in total. The reserve is claimed on Form T2017, Summary of Reserves on Dispositions of Capital Property.
Only one-half of a capital gain is taxable. The five-year spread is the general rule, but a 10-year reserve applies to some sales of qualified small business corporation shares to a child who is resident in Canada, and to certain intergenerational and qualifying business transfers. How the repayment schedule of a loan fits with the reserve, and how an uncertain earnout amount fits, depends on the facts and the wording, so confirm it with a tax professional.
When the reserve is not available or works differently
- No reserve is allowed if you were not resident in Canada, or were tax-exempt, at the end of the year or at any time in the following year.
- No reserve is allowed if the buyer is a corporation you control directly or indirectly, or a partnership in which you are a majority-interest partner immediately after the sale.
- If qualified small business corporation shares are sold to your child who is resident in Canada, the reserve can spread the gain over 10 years instead.
- Gains that are deferred, for example under a reserve, do not qualify for the capital gains deduction.
That last point matters if you plan to use the lifetime capital gains exemption. Whether and how to combine a reserve with the exemption is a planning question to settle before you sign.
What to do next
- Ask the buyer for a written term sheet showing cash at closing, the loan or earnout amount, and the dates.
- Ask what security, guarantees and default terms will back the deferred amount.
- Have an accountant estimate your tax each year with and without a reserve, including the possibility of alternative minimum tax on Form T691.
- Check whether any exception above applies to you or to the buyer.
- Have a lawyer review the agreement, note and security documents before you sign.
Frequently asked questions
Do I pay tax on the whole gain in the year I sell if the buyer pays me later?
Not necessarily. If part of the price is payable after the end of the year, you can generally claim a reserve, which spreads the gain over up to five years in total. Some sellers cannot claim it, so check the exceptions.
How do I claim the reserve?
The reserve is claimed on Form T2017, Summary of Reserves on Dispositions of Capital Property. An accountant normally prepares it with your return.
Can the reserve last longer than five years?
Generally no, since at least 1/5 of the gain is taxed each year and the whole gain is taxed within five years. A longer period of 10 years applies in some sales to a child and certain intergenerational transfers.
Is an earnout treated differently from a loan?
The practical risks differ, because an earnout amount depends on future results. How the tax rules apply to an uncertain amount depends on the wording of the agreement, so a lawyer or accountant should confirm it.
