Key takeaways
  • For tax purposes, fair market value is the highest price obtainable in an open market between informed, arm's-length parties with neither under compulsion.
  • The earnings method and the asset value method are the two most generally accepted bases of valuation.
  • A price is easier to defend when it is supported by documented factors such as earnings record, balance sheet and goodwill.

Before you list or negotiate, you need a number you can explain. Buyers will test it, and if the sale is to a related person, the tax authorities may test it too.

Valuation is part science and part judgment. This article explains the common approaches, what the Canada Revenue Agency (CRA) looks at, and how to prepare so your price holds up.

What "fair market value" means

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 words, it is what a well-informed stranger would pay when nobody is being pushed to do the deal.

The CRA's guidance on business valuation is a policy statement, not a law. It shows how the CRA tends to think, but the facts of your business still drive the result.

The two main methods

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

MethodBest suited toIdea
Earnings methodOperating businesses that make or sell products or servicesValue reflects what the business can earn, using a capitalization (multiple) rate
Asset value methodBusinesses that earn income mainly from their assets rather than the owners' personal effortsValue reflects the underlying worth of the assets

The CRA also says fair market value is generally the greater of liquidation value, used where the business is not viable as an ongoing operation, and going concern value, used where it can earn a reasonable return on investment.

Factors that justify a price

The CRA lists many factors for justifying a price. They include the nature and history of the business, industry outlook, balance sheet, earnings record and earning power, dividend capacity, goodwill and other intangibles, prior share sales, the size of the block, comparable public company prices and underlying asset value.

It also considers control versus minority interests and buy-sell agreements. Multiples reflect risks such as management depth, competition and ease of entry into the market.

Market multiples used in practice vary by industry, and there is no single official table of them. That is one reason an independent valuation or accountant's opinion can be useful.

Making your number easier to defend

If the buyer is related to you, or the price looks unusually high or low, expect more questions. A written valuation prepared at the time of the deal helps.

From value to price: allocation and tax

A valuation gives you a total. In an asset sale, the next question is how that total is split among the assets. Where an amount can reasonably be regarded as partly paid for property, services or a restrictive covenant, each part is treated separately.

If the sale agreement sets reasonable prices for individual assets, the CRA uses those prices. If it does not, the price is allocated to each asset at fair market value, then to inventory, and the remaining balance to goodwill.

Only one-half of a capital gain is taxable. Whether other relief, such as the lifetime capital gains exemption, applies to your sale depends on your situation, so it is worth confirming with a lawyer or accountant before you settle on a structure.

What to do next

Frequently asked questions

Is there a standard multiple for my industry?

Market multiples used in practice vary by industry, and no official source sets them. The CRA says multiples reflect risks such as management depth, competition and ease of entry. A valuator can tell you what is typical for your sector.

Which method should I use, earnings or assets?

The earnings method is used mainly for operating businesses that make or sell products or services, while the asset value method suits businesses earning income mainly from their assets. Many businesses are checked against both.

What if the business is not profitable?

Fair market value is generally the greater of liquidation value and going concern value. Liquidation value is used where the business is not viable as an ongoing operation.

Does the CRA have to accept my valuation?

The CRA's valuation guidance is a policy statement rather than law. A price supported by the listed factors and prepared by a qualified professional is easier to defend.
