Key takeaways
  • 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.

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.

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

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

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.
