Multinational transfer pricing: arm's length and section 247

Lessons 6 and 7 treated transfer pricing as an internal management problem: how to set prices that lead divisions to good decisions and allow fair evaluation. When divisions sit in different countries, a new consideration overwhelms the others. The transfer price determines how much of the group's profit is taxed in each country, and tax authorities everywhere insist that it be set as if the parties were unrelated. This lesson explains the arm's length principle, the methods tax authorities accept, the Canadian rules in section 247 of the Income Tax Act, documentation and penalties, and the tension between tax-driven and management-driven transfer prices. Tax facts are stated as of October 2026; ACCT-212 covers the accounting for income taxes and the global minimum tax in more depth.

Cormorant Europe

Cormorant Europe Ltd. is an Irish subsidiary that distributes Cormorant's heat pumps in the European Union. In 2027 it expects to buy 10,000 heat pumps from Appliances, which makes them in Hamilton at a full cost of $1,300 each, and to resell them to European installers. Cormorant Europe resells them for an average of $1,800 and incurs $300 a unit of its own selling and distribution costs, so the illustrative combined pre-tax profit on the heat pumps, across both countries, is $2,000,000. The question is how much of that profit belongs in Canada and how much in Ireland.

Why taxes change the transfer pricing problem

Corporate income tax rates differ between countries. Cormorant's combined federal and Ontario rate is 26.5 per cent, while Ireland's standard rate on trading income is 12.5 per cent for groups below the global minimum tax threshold; groups with consolidated revenue of €750 million or more pay at least 15 per cent under Ireland's Pillar Two rules. Every dollar of profit moved from the higher-tax country to Ireland saves the difference in rates. If Cormorant were free to choose, it would set a low transfer price on heat pumps sold to Ireland, keeping profit there, and a high price on anything Ireland sold back.

# Effect of the transfer price on Cormorant's group tax (illustrative rates; thousands)
units = 10_000                 # heat pumps sold by Appliances to Cormorant Europe
rate_parent, rate_ireland = 0.265, 0.125
group_pre_tax = 2_000          # combined pre-tax profit on the heat pumps
for tp in (1_380, 1_400, 1_420):
    parent = (tp - 1_300) * units / 1000      # Appliances' profit: cost 1,300 a unit
    europe = group_pre_tax - parent
    tax = parent * rate_parent + europe * rate_ireland
    print(f"TP {tp}: Canada profit {parent:>6,.0f}  Ireland profit {europe:>6,.0f}  group tax {tax:>6,.1f}")
print(f"Each $20 off the TP shifts {20 * units / 1000:,.0f} of profit and saves {20 * units / 1000 * (rate_parent - rate_ireland):,.0f} of tax")

TP 1380: Canada profit    800  Ireland profit  1,200  group tax  362.0
TP 1400: Canada profit  1,000  Ireland profit  1,000  group tax  390.0
TP 1420: Canada profit  1,200  Ireland profit    800  group tax  418.0
Each $20 off the TP shifts 200 of profit and saves 28 of tax

A $20 reduction in the transfer price moves $200,000 of profit to Ireland and reduces group tax by $28,000. At the median arm's length price of about $1,422 worked out below, profit would split roughly $1,220,000 to Canada and $780,000 to Ireland. Across many products and years, the amounts add up quickly, which is exactly why tax authorities scrutinize transfer prices and why the rules described below exist. Profit shifting through transfer prices, especially of intangibles such as patents and brands, was the central concern of the OECD's base erosion and profit shifting (BEPS) project, which began in 2013 and has reshaped international tax rules since.

The arm's length principle

Nearly every country, including Canada, the United States and Ireland, requires that transfer prices between related parties satisfy the arm's length principle: the price must be the one that unrelated parties would have agreed to in comparable circumstances. The principle is set out in Article 9 of the OECD Model Tax Convention and elaborated in the OECD Transfer Pricing Guidelines for Multinational Enterprises and Tax Administrations, most recently consolidated in 2022 with later updates. Applying it requires a comparability analysis: identifying the characteristics of the controlled transaction, the functions each party performs, the assets it uses and the risks it assumes, the contractual terms, the economic circumstances and the business strategies, and then finding uncontrolled transactions that are comparable.

In Canada, section 247 of the Income Tax Act gives the Canada Revenue Agency (CRA) power to adjust transfer prices that do not meet the arm's length standard, and to recharacterize transactions that would not have been entered into by arm's length parties. Amendments announced in Budget 2025 (4 November 2025) tie section 247 more explicitly to the OECD Guidelines and focus the analysis on the actual conduct of the parties rather than their contracts alone; check the status of these amendments before relying on them.

Transfer pricing methods for tax

The OECD Guidelines describe five main methods, and tax authorities generally require the most appropriate method for the circumstances. Traditional transaction methods compare prices or gross margins directly; transactional profit methods compare net profits.

The example shows that the arm's length principle rarely gives a single right answer. It defines a range, and companies have some room to choose within it. Choosing a price at the bottom of the range for sales into Ireland is legal tax planning; choosing one below the range is not. In practice, tax authorities often challenge prices at the edge of the range, and the burden of supporting the comparables falls on the taxpayer.

Documentation and penalties

Canada requires taxpayers to make reasonable efforts to determine and use arm's length transfer prices, and treats contemporaneous documentation as the evidence of those efforts. Under section 247(4), the documentation must exist by the filing due date for the year. Under the Budget 2025 amendments, the CRA may request it with a 30-day deadline, shortened from three months. If the CRA adjusts transfer prices and the net adjustment exceeds a threshold, a penalty of 10 per cent of the excess applies under section 247(3) unless the taxpayer made reasonable efforts. The threshold is the lesser of 10 per cent of gross revenue and, for taxation years beginning after 4 November 2025, $10 million (previously $5 million). The penalty is not tax deductible and is charged in addition to the extra tax and interest.

# Section 247(3) penalty for a larger group (illustrative)
gross_revenue = 300_000_000
adjustment = 12_000_000          # net transfer pricing adjustment by the CRA
threshold = min(0.10 * gross_revenue, 10_000_000)
penalty = 0.10 * max(0, adjustment - threshold)
print(f"Threshold: {threshold:,.0f}")
print(f"Penalty if reasonable efforts were not made: {penalty:,.0f}")
print("Penalty if contemporaneous documentation shows reasonable efforts: 0")

Threshold: 10,000,000
Penalty if reasonable efforts were not made: 200,000
Penalty if contemporaneous documentation shows reasonable efforts: 0

For this larger group the penalty is $200,000, on top of tax on the $12 million adjustment, unless documentation shows reasonable efforts. Because 10 per cent of gross revenue ($30 million) exceeds $10 million, the dollar limit sets the threshold. A smaller company such as Cormorant itself, with consolidated revenue under $100 million, would face the 10 per cent of revenue test instead, so its threshold could be well below $10 million.

Beyond penalties, the main risk is double taxation. If one country adjusts a transfer price upward and the other does not make a corresponding downward adjustment, the same profit is taxed twice. Tax treaties provide a mutual agreement procedure (MAP) under which the two countries' competent authorities try to resolve such cases, and many treaties now include arbitration. Companies can reduce uncertainty in advance with an advance pricing arrangement (APA), an agreement with one or more tax authorities on the method for future transactions, typically for three to five years.

Country-by-country reporting and BEPS

Following BEPS Action 13, large multinational groups must file a country-by-country report showing, for each country in which they operate, revenue, profit before tax, income tax paid and accrued, employees, capital and tangible assets. The threshold is consolidated group revenue of €750 million under the OECD standard, which Canada applies. Groups also prepare a master file describing the global business and transfer pricing policies, and local files for each country, though requirements vary by jurisdiction. Cormorant is below the threshold, but its competitors may not be, and the reports let tax authorities spot profit that sits in low-tax countries with few employees or assets.

The global minimum tax under Pillar Two, which Canada enacted in the Global Minimum Tax Act in 2024, reduces but does not eliminate the incentive to shift profit. A group in scope that books profit in a country with a 12.5 per cent rate pays top-up tax to bring its effective rate to 15 per cent, so the saving shrinks rather than disappears. ACCT-212 covers the accounting.

Customs duties and other conflicts

Income tax is not the only consideration. When goods cross a border, customs duties are usually charged on the declared value, which is often the transfer price. A high transfer price on imports raises duties in the importing country while lowering income tax there; a low price does the reverse. Customs and tax authorities in the same country may therefore push in opposite directions, and companies must be consistent in what they tell each. Other factors include currency controls that limit the repatriation of profits, political risk, local partners' interests in joint ventures and government price regulation, all of which can favour higher or lower transfer prices in particular countries.

Tax prices and management prices

The transfer price that best serves tax compliance is often not the one that best serves management control. A tax-driven price might leave Cormorant Europe with a routine distributor's margin, around 2 to 4 per cent of sales on a net basis, and all residual profit in Canada, even though Europe's managers are building a market whose value will show up in future years. Evaluated on that profit, the European managers would look mediocre regardless of performance, and if their bonuses depended on it, they would have reason to resist investments that help the group.

Companies respond in two broad ways. Some keep one set of transfer prices for both purposes, accepting some distortion in performance evaluation for simplicity and consistency, and because tax authorities may treat differences between internal and tax prices as evidence that the tax price is not arm's length. Others keep separate management accounts, adjusting divisional results to a management transfer price, or evaluating managers on measures, such as sales growth, gross margin before transfer price or market share, that are not affected by the tax price. Surveys of multinationals suggest most use the same price for both purposes, with adjustments at the evaluation stage rather than a second set of prices.
