Key takeaways
  • For tax purposes the CRA defines fair market value as the highest price obtainable in an open and unrestricted market between informed, prudent parties at arm's length, with neither under compulsion.
  • The CRA treats the earnings method and the asset value method as the two most generally accepted bases of valuation, and value is generally the greater of liquidation value and going concern value.
  • Once a price is set, how it is allocated among assets decides the seller's proceeds and the buyer's cost, so valuation affects tax on both sides.

Setting a price for a business is part negotiation and part evidence. If the price is ever questioned for tax purposes, you will want to show how you got there, and the CRA has published its own approach to business equity valuations.

This article explains that approach in plain words: what fair market value means, the two main valuation methods, the factors the CRA looks at, and why the numbers matter once a deal closes. It is general information for Ontario owners and buyers, not a valuation.

What fair market value means to the CRA

For tax purposes, the CRA defines fair market value as the highest price obtainable in an open and unrestricted market between knowledgeable, informed and prudent parties acting at arm's length, with neither party under compulsion to transact.

In plain terms, it is not a bargain price, a rushed price or a price between family members that reflects something other than value. It is what well-informed strangers would agree on if neither had to deal.

The CRA sets this out in Information Circular IC89-3, a policy statement on business equity valuations.

The two main valuation methods

The CRA treats the earnings method and the asset value method as the two most generally accepted bases of valuation.

MethodGenerally used for
Earnings methodOperating businesses that make or sell products or services
Asset value methodBusinesses that earn income mainly from their assets rather than from the owners' personal efforts

Which method fits depends on how the business actually makes money. A valuator will often look at more than one method and compare the results.

Liquidation value and going concern value

The fair market value of a business is generally the greater of its liquidation value and its going concern value.

So a business that earns a good return is usually valued as a running operation, while one that cannot is valued on what its assets would bring if wound up.

Factors the CRA weighs, and what is not set by law

To justify a price, the CRA lists a range of factors:

Capitalization (multiple) rates reflect risks such as management depth, competition and ease of entry into the market. A business that depends on one key person, or that faces many competitors, is generally seen as riskier.

No official source sets industry multiples. Rules of thumb you hear in practice vary by industry and should be treated as starting points, not answers.

Why the number matters after closing

Where an amount can reasonably be regarded as partly paid for different property, services or a restrictive covenant, each part is treated separately. The part attributable to a property is that property's proceeds for the seller and its cost for the buyer.

If the agreement sets reasonable prices for individual assets, the CRA uses them. If not, the price goes to each asset at fair market value, then to inventory, and the remaining balance to goodwill.

This affects tax on both sides. For the seller, more price on depreciable equipment can create recaptured depreciation, which is included in income in full. Only one-half of a capital gain is taxable. For the buyer, the allocation changes future deductions, since goodwill goes into Class 14.1 and fixed assets go into their own classes.

What to do next

Valuation depends heavily on the facts of each business, so professional advice is worth getting before you set or accept a price.

Frequently asked questions

Is IC89-3 a law I must follow?

No. It is a CRA policy statement on business equity valuations, not legislation. It shows how the CRA approaches value, so it is a useful guide, but the facts of your business still decide the result.

Which method is used for a small operating business?

The earnings method is used mainly for operating businesses that make or sell products or services. The asset value method suits businesses that earn income mainly from their assets. A valuator may use both and compare them.

Is there a standard multiple for my industry?

No official source sets industry multiples. Multiples used in practice vary by industry, and the risks the CRA mentions, such as management depth and competition, affect the rate.

What happens to price that is not assigned to a specific asset?

If the agreement does not set reasonable prices for individual assets, the CRA allocates price at fair market value to each asset, then to inventory, and the remaining balance to goodwill. A lawyer or accountant can help you plan this before closing.
