Fair market value is the most commonly required standard of value in Canadian business valuation. The term appears over 1,000 times in the Income Tax Act. CRA uses it. Courts use it. Buyers, sellers, and their advisors use it. But the definition is more precise — and more demanding — than most people realize. Here is what fair market value actually means, how it is determined, and why the inputs to the calculation matter more than the formula.
Fair market value is defined in Canadian case law as:
This is not a guideline. It is the legal standard that CRA applies when reviewing valuations filed in connection with tax transactions. It is the standard most Canadian courts apply when determining the value of a business interest in family law proceedings. It is the standard used in expropriation proceedings, estate settlements, and most arm’s-length business sales.
Every word in the definition matters. “Highest price” means the FMV is the ceiling, not the average — the price a motivated buyer would pay in competition with other buyers. “Open and unrestricted market” means no barriers to entry for buyers or sellers. “Knowledgeable, informed and prudent” means both parties have access to the same information and are exercising reasonable judgment. “Arm’s length” means no special relationship between the parties. “No compulsion” means neither party is forced to transact.
| Condition | What It Means | How Real Transactions Fail This Test |
|---|---|---|
| Open and unrestricted market | The business is exposed to the full range of potential buyers with no artificial barriers limiting who can participate. | Many private business sales are negotiated with a single buyer, never exposed to the market. Franchise resales are restricted by franchisor approval. Shareholder agreements may limit who shares can be sold to. |
| Knowledgeable and informed parties | Both buyer and seller have access to all material information about the business: financial performance, risks, intangible assets, liabilities, and market conditions. | In practice, information asymmetry is the norm. Sellers know more about the business than buyers. Buyers conduct due diligence, but undisclosed risks are common. |
| Prudent parties | Both parties are acting with reasonable care and sound judgment, not emotionally or recklessly. | Many business sales involve emotional attachment (seller) or excitement about potential (buyer). Neither is acting with the cold rationality FMV assumes. |
| Arm’s length | The parties have no special relationship — not family, not business partners, not employer/employee — that would influence the price. | A large percentage of private business transfers occur between related parties: parent to child, business partner to partner, employer to key employee. CRA scrutinizes these transactions specifically because they are not arm’s length. |
| No compulsion to transact | Neither party is forced to buy or sell by financial pressure, legal requirement, health issues, or external circumstances. | Divorce requires division of assets. Death triggers deemed disposition. Expropriation is compelled by the government. Creditor pressure forces sales. Many transactions occur under compulsion that FMV assumes does not exist. |
The five conditions describe a market that rarely exists for private businesses. There is no stock exchange for small companies. Buyers and sellers are rarely equally informed. Transactions are often between related parties, often under some degree of pressure. Fair market value is not what the business will actually sell for — it is what it would sell for if the market were perfect. The valuator’s job is to estimate that hypothetical price using the best available evidence about what the real market would produce under ideal conditions.
Fair market value is not a prediction of what the business will sell for. It is not what the owner thinks it is worth. It is not what a specific buyer has offered. It is the price a hypothetical buyer would pay a hypothetical seller in a hypothetical market that meets all five conditions simultaneously.
This matters because every real transaction deviates from the hypothetical. A business sold in a divorce may sell under time pressure (violating the no-compulsion condition). A business transferred to a child may be sold at a below-market price (violating the arm’s-length condition). A business sold to a single buyer without market exposure may sell for less than an open-market sale would produce (violating the open-market condition).
CRA applies the hypothetical standard regardless of the actual transaction price. If you transfer your business to your child for $200,000 but the FMV is $500,000, CRA treats the transaction as if it occurred at $500,000 and assesses tax accordingly. The actual price paid is irrelevant for tax purposes when the transaction is not at arm’s length. This is why a defensible FMV determination is not optional for tax transactions — it is the price that CRA will use whether you provide one or not.
| Standard of Value | Definition | When It Is Used | Key Difference from FMV |
|---|---|---|---|
| Fair market value | Highest price in an open market between informed, arm’s-length parties under no compulsion. | Income Tax Act transactions, most family law, expropriation, estate planning, arm’s-length sales. | — |
| Fair value | The value of a business interest without minority or marketability discounts. An equitable standard designed to protect shareholders from being undercompensated. | Oppression remedy (CBCA s. 241), dissent and appraisal rights (CBCA s. 190), some provincial shareholder remedies. | No minority discount. No marketability discount. Often 30%–40% higher than FMV for minority interests. |
| Investment value | The value to a specific buyer, reflecting that buyer’s unique synergies, strategic advantages, or cost savings. | Strategic acquisitions, private equity transactions, internal business cases for acquisitions. | Buyer-specific. Includes synergies. May be higher or lower than FMV depending on the buyer’s circumstances. |
| Liquidation value | The amount realized if the business’s assets are sold individually, liabilities are paid, and the business is closed. | Insolvency, bankruptcy, wind-up scenarios, businesses with no going-concern value. | No going-concern premium. No goodwill. Typically the lowest standard of value. |
| Transaction or Context | Income Tax Act Reference | Why FMV Is Needed |
|---|---|---|
| Estate freeze (share exchange) | Section 86 | The freeze shares must be issued at FMV. If FMV is wrong, the freeze fails and tax consequences follow. |
| Rollover of property to corporation | Section 85 | The elected amount must be between the tax cost and FMV. An incorrect FMV can trigger immediate tax or create future exposure. |
| Deemed disposition on death | Subsection 70(5) | All capital property is deemed disposed at FMV immediately before death. The estate owes tax on the resulting capital gain. |
| Transfer between related parties | Section 69 | Transfers not at arm’s length are deemed to occur at FMV. If the actual price is below FMV, CRA reassesses at FMV. |
| Stock option benefit | Section 7 | The employee benefit is calculated as FMV at the time shares are acquired minus the exercise price. |
| Lifetime capital gains exemption | Section 110.6 | The exemption is calculated based on the FMV of qualifying shares at the time of disposition. |
| Charitable donation of shares | Section 118.1 | The tax credit is based on the FMV of the donated property. |
| Family law equalization | Provincial family law statutes | FMV of business interests is included in net family property for equalization. |
| Expropriation | Federal and provincial Expropriation Acts | Market value (equivalent to FMV) is the basis for compensation for property taken for public use. |
The three established approaches to determining the FMV of a private business are the income approach, the asset approach, and the market approach. For most small and mid-size operating businesses, the income approach is primary, with the asset approach and market data serving as secondary checks.
Income approach. The business’s expected future earnings are estimated based on historical performance (normalized for non-recurring items and owner-specific expenses) and then capitalized at a rate that reflects the risk of the business. Higher risk means a higher capitalization rate, which means a lower value. Lower risk means a lower capitalization rate and a higher value. The critical judgment is in the capitalization rate — specifically, the company-specific risk premium, which is the adjustment for risks unique to this particular business.
Asset approach. The fair market value of the business’s individual assets (tangible and identifiable intangible) is determined, and the liabilities are subtracted. This approach is typically used when the business has no going-concern value (it is not worth more as an operating enterprise than the sum of its parts) or when the business is an investment or real estate holding company.
Market approach. The business is compared to similar businesses that have sold, using transaction multiples (price as a multiple of earnings, revenue, or assets). This approach is useful as a reasonableness check but is rarely the primary methodology for private businesses because the comparable transactions involve different businesses under different circumstances with different intangible asset profiles.
The fair market value formula is straightforward: normalized earnings divided by the capitalization rate. The formula is not where the disagreement happens. Two valuators using the same formula will produce different values if they disagree on the inputs.
| Input | What It Requires | How It Affects Value |
|---|---|---|
| Normalized earnings | Historical earnings adjusted for non-recurring revenue and expenses, owner compensation above or below market rate, personal expenses run through the business, and one-time events. | Higher normalized earnings = higher value. The adjustments are judgment calls, and different valuators may normalize differently. |
| Capitalization rate | A risk-adjusted rate that converts a stream of earnings into a present value. Built up from a risk-free rate, an equity risk premium, a size premium, an industry risk premium, and a company-specific risk premium. | Higher cap rate = lower value. A 1% change in the cap rate can change the value by 15%–25%. The company-specific risk premium is the most subjective component. |
| Company-specific risk premium | An adjustment for risks unique to this business: owner dependency, client concentration, workforce fragility, competitive vulnerability, regulatory exposure, and other factors not captured in the general risk premiums. | This is where the valuation is won or lost. A 5% company-specific risk premium versus a 10% premium can change the value by 30%–50%. Without on-site inspection, this number is a guess. |
| Intangible asset identification | Identifying which intangible assets exist, whether they are transferable (commercial goodwill) or non-transferable (personal goodwill), and how durable they are. | Determines what portion of the value would actually transfer to a hypothetical buyer. FMV only includes value that transfers in the hypothetical transaction. |
CRA’s Business Equity Valuations section, operating under Information Circular IC 89-3, reviews valuations filed in connection with tax transactions. The Regional Valuation Officer may request financial statements for the five most recent fiscal periods, details of the valuation methodology, supporting schedules, appraisals of fixed assets, and any documents bearing on the value of the business interest.
CRA’s review focuses on whether the valuation is consistent with the legal definition of FMV, whether the methodology is appropriate for the type of business and the purpose of the valuation, whether the inputs are reasonable and supported by evidence, and whether the conclusion is within a range that the CRA’s own analysis would produce.
CRA does not require a specific methodology. It requires that whatever methodology is used produces a result that is reasonable and defensible. A valuation that uses the income approach with a well-documented capitalization rate, supported by on-site inspection findings and specific intangible asset identification, is more defensible than one that uses a round-number capitalization rate with no supporting analysis.
If CRA disagrees with the FMV, it can reassess the transaction. The taxpayer can object and, if the objection is not resolved, appeal to the Tax Court of Canada. At that point, the valuation report must withstand cross-examination — and the valuator may be called as an expert witness to defend the methodology, the inputs, and the conclusion.
FMV is not your opinion of value. It is not what you need for retirement. It is not what your accountant said over coffee. It is the hypothetical price in the hypothetical market defined by the five conditions. Personal expectations, emotional attachment, and financial need are irrelevant to FMV.
Applying fair value when FMV is required (or vice versa) produces the wrong number. The difference can be 30% to 40% for minority interests. A valuation report that does not identify which standard of value is being applied is immediately suspect.
A valuation that uses “a capitalization rate of 25%” without building it up from its components — risk-free rate, equity premium, size premium, industry premium, and company-specific premium — is asserting a conclusion rather than demonstrating one. The company-specific risk premium requires evidence about the specific business, which requires on-site inspection.
FMV only includes value that would transfer in a hypothetical arm’s-length sale. Personal goodwill — value dependent on the current owner — does not transfer. A valuation that includes personal goodwill in FMV overstates what a hypothetical buyer would pay.
The Income Tax Act does not require an on-site inspection. CRA does not require one. But the company-specific risk premium, the intangible asset identification, and the distinction between personal and commercial goodwill all require direct observation of the business in operation. A valuator who has not visited the business is estimating these critical inputs without evidence. The formula will still produce a number. The number will just be less defensible.
The 25 Factors Affecting Business Valuation framework is a structured method for gathering the evidence that populates the most important inputs in an FMV determination. Each factor addresses a specific aspect of the business that affects risk, transferability, and earning capacity:
Factors affecting normalized earnings: revenue sustainability, expense structure, owner compensation analysis, non-recurring items, growth trajectory. Factors affecting the capitalization rate: owner dependency, client concentration, workforce depth, competitive vulnerability, regulatory exposure, industry risk, technology risk. Factors affecting intangible asset identification: client base characteristics (loyalty, concentration, contract terms), brand strength, operational systems, process documentation, employee expertise, contractual assets, lease value.
The 5 Senses Inspection Report populates these factors with evidence gathered through on-site observation. The valuator sees how the business operates, who the clients interact with, how the workforce functions when the owner is absent, where the operational knowledge resides, and what the physical condition of the assets reveals about management quality. This evidence determines the company-specific risk premium, the intangible asset classification, and the distinction between personal and commercial goodwill — the three inputs that most affect the FMV conclusion.
The result is a fair market value determination where every material input is supported by specific, documented, observable evidence rather than assumption. This is the valuation that withstands CRA review, survives cross-examination, and gives the reader confidence that the number means what it says.
No. The asking price is what the seller wants. The selling price is what the parties agreed to. FMV is what a hypothetical buyer would pay in a hypothetical perfect market. The actual selling price may be higher than FMV (if the buyer is paying a strategic premium), lower than FMV (if the seller is under pressure), or equal to FMV (if the transaction closely resembles the hypothetical conditions). CRA uses FMV, not the actual transaction price, for tax purposes.
Yes, and they commonly do. FMV is not a single number — it is a range. Qualified valuators may disagree on the appropriate normalized earnings, the capitalization rate components, or the classification of intangible assets. A well-supported valuation will fall within a reasonable range. If two valuations differ by 10% to 15%, both may be defensible. If they differ by 40% or more, at least one of them has a material error in its inputs or methodology.
Not strictly for CRA purposes, because CRA generally accepts that an arm’s-length transaction price reflects FMV. However, a valuation is valuable for the seller (to know the business’s worth before negotiating), for the buyer (to confirm the price is supported), and for the purchase price allocation (to allocate the price across asset categories for CCA purposes). In a non-arm’s-length transaction, a valuation is essential because CRA will not assume the price reflects FMV.
An FMV valuation is valid as of its valuation date. FMV can change as the business’s financial performance, risk profile, and market conditions change. A valuation prepared as of December 31, 2024 reflects the business’s value on that date. If the business’s circumstances change materially (loss of a key client, departure of a key employee, significant revenue growth or decline), the FMV changes with them. For tax transactions, the valuation date should be as close as possible to the transaction date.
Valuators offer different levels of engagement: calculation (limited scope, lower cost, lower assurance), estimate (moderate scope, moderate cost, moderate assurance), and comprehensive (full scope, higher cost, full assurance). The appropriate level depends on the purpose. A $3,500 estimate valuation may be sufficient for a business sale negotiation. A $10,000+ comprehensive valuation may be necessary for a CRA-sensitive estate freeze or a contested divorce. The cost of the valuation should be proportionate to the amount at stake and the likelihood of scrutiny.
The legal definition of FMV is consistent across Canada because it originates from federal case law and the federal Income Tax Act. However, the application can vary in provincial family law (some provinces may apply different standards for certain purposes) and in provincial expropriation statutes (Quebec uses “value to the owner,” which is broader than FMV). For tax purposes, FMV is the same standard nationwide.
There is no legal requirement for an on-site visit. But the most important inputs in the valuation — the company-specific risk premium, the distinction between personal and commercial goodwill, and the identification of transferable intangible assets — can only be assessed with confidence through direct observation. A valuator who determines FMV from financial statements alone is making assumptions about these inputs that an on-site inspection would confirm or contradict. The on-site inspection does not change the formula. It changes the evidence supporting the inputs — and evidence is what survives scrutiny.
