Transfer Pricing Between Canada and US Related Companies: What the Rules Require

When a Canadian company and a US company under common ownership transact with each other, both tax authorities scrutinize the prices charged. If a Canadian parent charges its US subsidiary above-market management fees, the IRS can cut the subsidiary’s deduction and increase its US income. If a US parent charges its Canadian subsidiary inflated royalties, the CRA can reduce the Canadian subsidiary’s deduction. Both adjustments are based on the same principle: related-party transactions must be priced as if the parties were dealing at arm’s length.

What transactions are covered?

Transfer pricing rules apply to any transaction between related parties where one party is in Canada and the other is in the US. “Related” means common ownership or control, broadly defined. A Canadian parent and its US subsidiary are related. Two subsidiaries of the same parent are related. An individual who controls both a Canadian company and a US company creates a related-party relationship.

Common intercompany transactions that require arm’s-length pricing:

• Management fees: A parent company provides management, accounting, HR, or IT services to a subsidiary. The fee must reflect the cost of the services (including a reasonable markup) or the price an independent party would charge for comparable services.
• Royalties and licensing fees: One entity licenses intellectual property (trademarks, patents, software, trade secrets) to the other. The royalty rate must be consistent with what an independent licensee would pay.
• Intercompany loans: A parent lends money to a subsidiary (or vice versa). The interest rate must be arm’s length, reflecting the borrower’s creditworthiness and the loan terms.
• Cost-sharing arrangements: Two related entities share the cost of developing intellectual property or other assets. The contributions must be proportional to the anticipated benefits.
• Sale of goods: A manufacturer in one country sells finished goods to a distributor in the other country. The transfer price affects where the profit is recognized.
• Commissions: A subsidiary acts as a sales agent for the parent. The commission rate must reflect arm’s-length compensation for the services performed.

How does the US enforce transfer pricing?

IRC 482 gives the IRS broad authority to allocate income, deductions, credits, and allowances among related organizations, trades, or businesses if the allocation is necessary to prevent evasion of taxes or to clearly reflect income. The IRS does not need to prove intent; it only needs to show that the prices charged are not arm’s length.

The Treasury Regulations under IRC 482 prescribe specific methods for determining arm’s-length prices:

• Comparable uncontrolled price (CUP): The price charged in a comparable transaction between unrelated parties.
• Resale price method: The resale price to an independent buyer, minus a gross margin based on comparable resellers.
• Cost plus method: The cost of providing the service or good, plus a markup based on comparable transactions.
• Comparable profits method (CPM): A widely used method. Compares the tested party’s operating profit margin to those of comparable independent companies.
• Profit split method: Splits the combined profit between the related parties based on their relative contributions.

The IRS requires the “best method” rule: the taxpayer must use whichever method produces the most reliable measure of arm’s-length result given the facts.

Penalties: IRC 6662(e) imposes a 20% penalty on the underpayment attributable to a transfer pricing adjustment if the transfer price is 200% or more (or 50% or less) of the arm’s-length price, and a 40% penalty if it is 400% or more (or 25% or less). A separate net adjustment penalty applies when total section 482 adjustments for the year exceed the lesser of $5 million or 10% of gross receipts (40% above $20 million or 20%). The penalty is avoided if the taxpayer maintained contemporaneous documentation demonstrating reasonable reliance on a transfer pricing method.

Documentation requirements: The contemporaneous documentation must exist at the time the return is filed (Reg 1.6662-6(d)). It must include a description of the business, the controlled transactions, the method selected, the comparable data, and the economic analysis supporting the arm’s-length price.

How does Canada enforce transfer pricing?

ITA 247 is Canada’s transfer pricing provision. It applies to transactions between a Canadian taxpayer and a non-resident with whom the taxpayer does not deal at arm’s length. The CRA can adjust the Canadian taxpayer’s income or deductions to reflect arm’s-length amounts.

Canada follows the same OECD methods as the US (CUP, resale price, cost plus, TNMM (the OECD equivalent of CPM), and profit split). The CRA’s old Information Circular IC 87-2R (International Transfer Pricing) has been cancelled; ITA 247 now points directly to the OECD Transfer Pricing Guidelines.

Documentation requirements (ITA 247(4)): Canadian taxpayers must maintain contemporaneous documentation that includes a description of the property or services, the terms and conditions of the transaction, the transfer pricing method used, the assumptions and data relied on, and an analysis of the method’s application. The documentation must be prepared by the taxpayer’s filing due date.

Penalties: If the CRA makes a transfer pricing adjustment and the taxpayer did not maintain adequate documentation, a penalty of 10% of the adjustment amount can apply under ITA 247(3), but only when the net adjustment exceeds the lesser of 10% of gross revenue and $10 million ($5 million for tax years that began before November 5, 2025). This is in addition to the regular tax on the adjustment. For a company with $3 million of revenue, a $500,000 adjustment clears that bar, so the penalty is $50,000, on top of the tax on the additional $500,000 of income.

The only relief written into ITA 247(3) is for amounts where you made reasonable efforts to price at arm’s length. ITA 247(4) treats you as not having made reasonable efforts unless the contemporaneous documentation exists by your filing due date and you hand it over within 30 days of a CRA request (3 months for tax years that began before November 5, 2025), so (as in the US) the documentation is what protects you.

How do you prevent double taxation from adjustments?

When one country makes a transfer pricing adjustment, the same income is taxed in both countries unless the other country makes a corresponding adjustment. The treaty provides two mechanisms:

Article IX (Related Persons): If the US makes a transfer pricing adjustment that increases the US subsidiary’s income, the Canadian parent can request a corresponding reduction from the CRA. The CRA is not obligated to agree, but the treaty says it “shall” make a corresponding adjustment if it agrees with the original adjustment and its competent authority was notified within six years of the end of the year involved. In practice, the CRA reviews the US adjustment independently and may agree to a different amount.

Competent Authority proceeding: If the two countries cannot agree on the appropriate adjustment, the taxpayer can request a Competent Authority proceeding under Article XXVI of the treaty. The competent authorities (the IRS and the CRA) negotiate directly to resolve the double taxation. The proceeding can take years. Since the 2007 Protocol, a qualifying case the competent authorities can’t settle goes to binding arbitration, as long as everyone involved agrees.

Advance pricing agreement (APA): A proactive alternative. The taxpayer proposes a transfer pricing methodology to one or both tax authorities, and the authorities agree in advance that the methodology is acceptable. A bilateral APA (agreed by both the IRS and the CRA) provides certainty for a defined period of years. The downside: APAs are expensive to prepare and can take years to negotiate.

What does a small or mid-size business need to do?

Most cross-border small and mid-size businesses do not need a full-blown transfer pricing study. But they do need:

1. An intercompany agreement. A written contract that specifies the services provided, the pricing methodology, the payment terms, and the arm’s-length basis. This contract should be signed before the services begin, not retroactively.

2. A contemporaneous memo. A brief (5 to 15 page) document that describes the intercompany transactions, identifies the transfer pricing method used, and supports the arm’s-length price with comparable data. This memo should be completed before the tax return is filed.

3. Consistent reporting. Both entities report the same intercompany amounts. If the Canadian parent charges $300,000 in management fees, the US subsidiary deducts $300,000. Any inconsistency is a red flag.

4. Annual review. The arm’s-length price should be reviewed annually. Comparable data changes, the scope of services changes, and the business relationship evolves. A price set in 2020 may not be arm’s length in 2026.

A basic transfer pricing memo for a small cross-border group usually costs far less than a transfer pricing adjustment with penalties and interest. The documentation is insurance.

What forms are required?

US side:

• Form 5472 (Information Return of a 25% Foreign-Owned U.S. Corporation or a Foreign Corporation Engaged in a U.S. Trade or Business): filed with the US subsidiary’s Form 1120, reporting each reportable transaction with related parties. Penalty for failure to file: $25,000 per return under IRC 6038A(d).
• Form 1120, Schedule M-1 or M-3: reconciles book income to taxable income, where transfer pricing adjustments would appear.
• Contemporaneous documentation (maintained, not filed, but must be produced within 30 days of an IRS request).

Canadian side:

• Form T106 (Information Return of Non-Arm’s Length Transactions with Non-Residents): filed with the Canadian parent’s T2 return when its reportable transactions with non-arm’s length non-residents total more than $1,000,000 in the year, reporting those transactions. Late-filing penalty: $25 a day ($100 minimum, $2,500 maximum), or $500 a month for up to 24 months ($12,000) if the failure is knowing or grossly negligent.
• T2 return with appropriate income/deduction reporting.
• Contemporaneous documentation (maintained, not filed, must be produced within 30 days of a CRA request for tax years that begin after November 4, 2025, or within 3 months for earlier years).
