What Is Article 7 of the OECD Model Tax Convention?

Article 7 of the OECD Model Tax Convention decides which country gets to tax a company’s cross-border business profits. The rule is straightforward in principle: a company resident in one treaty country is taxed only at home on its business profits, unless it operates in the other country through a permanent establishment. When a permanent establishment exists, the host country can tax the profits attributable to that local operation, and nothing more. This single provision sits at the center of nearly every bilateral tax treaty in force today.

When Does a Host Country Get to Tax Foreign Business Profits

Article 7, paragraph 1, sets the entry gate. A company resident in one treaty country is shielded from income tax in the other country unless it carries on business there through a permanent establishment.¹ Having customers in a foreign country, or making sales into it, does not by itself give that country the right to tax you. Something more tangible has to be on the ground.

A permanent establishment generally means a fixed place of business through which the company carries on operations. A branch office, factory, or workshop qualifies. So does a dependent agent who habitually concludes contracts for the company. The place must have both a specific geographic location and some degree of permanence; temporary or one-off activities at a site typically fall short.² The OECD Commentary notes that operations maintained at a fixed place for less than six months have generally not been treated as permanent establishments, though there is no bright-line rule.³

Even when a permanent establishment exists, the host country’s reach is limited to the profits attributable to that establishment, not the company’s worldwide income. If no permanent establishment exists, the host country has no treaty basis to impose corporate income tax on the business at all.

Activities That Don’t Create a Permanent Establishment

Not every fixed location triggers tax obligations. Article 5, paragraph 4, of the OECD Model carves out several activities that do not create a permanent establishment, even when carried out at a fixed place of business. The common thread is that they are preparatory or auxiliary rather than core revenue-generating functions.

The excluded activities include:⁴

Using a facility solely to store, display, or deliver the company’s goods.
Keeping a stock of goods solely so another enterprise can process them.
Running a local office solely to purchase goods or collect information for the company.
Any other activity of a preparatory or auxiliary character, such as market research or quality testing that does not directly generate revenue.
A combination of the above, provided the overall operation remains preparatory or auxiliary.

Following the Base Erosion and Profit Shifting (BEPS) reforms, the OECD tightened these exceptions. Each listed activity now qualifies only if it is genuinely preparatory or auxiliary. A new anti-fragmentation rule prevents companies from splitting a cohesive business across multiple locations or related entities so that each fragment, viewed on its own, looks preparatory. If the combined operation is not preparatory or auxiliary in character, a permanent establishment exists.⁴

How the Attributable Profits Are Calculated

Article 7, paragraph 2, tells you how to measure the profits a host country can actually tax. The approach treats the permanent establishment as if it were a separate company dealing at arm’s length with its own head office.¹ This legal fiction stops companies from inflating or deflating local profits through internal bookkeeping.

The methodology is called the Authorized OECD Approach, and it works in two steps.⁵ The first step is a functional and factual analysis that builds a profile of the permanent establishment as a hypothetical standalone business. You identify the “significant people functions” performed locally and use those functions to decide which assets, risks, and capital belong to the PE. A manufacturing branch where local managers make production decisions and bear inventory risk looks very different from a sales office that only takes orders. The people on the ground, and the decisions they make, drive the analysis.

The second step prices the internal dealings between the PE and the rest of the enterprise as if they were transactions between unrelated parties. You apply the same transfer pricing methods used between separate companies: find comparable transactions, select the most appropriate method, and calculate what an independent business would have charged. If the head office supplies raw materials to the branch, the internal transfer price should match what an outside supplier would charge in the open market.⁵

This two-step process is where most compliance effort concentrates. Overstate the PE’s profits and you overpay locally; understate them and you invite an audit adjustment that can cascade into double taxation.

Deductions and Internal Dealings

Because the permanent establishment is treated as if it were independent, it can claim deductions for the costs of running its operations. These include not just locally incurred expenses but also a fair share of head-office overhead. If central management handles legal compliance, payroll, or IT infrastructure for all branches from one location, the PE should bear a proportionate share of those costs, and the host country must allow the deduction.

Under the Authorized OECD Approach, this logic extends to internal dealings that would create taxable payments between unrelated parties. If the head office owns a patent that the branch uses in manufacturing, the analysis recognizes a notional royalty from the PE to the head office. The PE deducts that notional payment, reducing its taxable income in the host country. The same principle applies to internal funding arrangements that resemble loans.⁵

One boundary matters here. Many bilateral treaties in force use the pre-2010 version of Article 7, which included a separate paragraph explicitly addressing expense deductions. Several major economies, including Argentina, Brazil, India, and Russia, continue to interpret Article 7 under the older framework. If your treaty was signed before the 2010 update, check which structure it follows, because the mechanics of expense recognition differ.

Corresponding Adjustments When Countries Disagree

Article 7, paragraph 3, addresses what happens when one country adjusts the PE’s profits upward. If Country A decides the PE earned more than reported and raises the local tax bill, the company faces double taxation unless Country B drops its own claim on the same profits. Paragraph 3 requires Country B to make a corresponding downward adjustment, but only if it agrees the revised figure reflects the arm’s length standard.¹

Country B is not obligated to accept the adjustment automatically. The OECD Commentary makes clear that a corresponding adjustment is required only to the extent the other country considers the revised profits consistent with what the PE would have earned as an independent enterprise.⁶ When the two sides disagree, the taxpayer can end up paying more than the full amount of profit in combined taxes until the dispute is resolved.

When Specific Income Articles Take Priority

Article 7, paragraph 4, sets a hierarchy between the general business profits rules and the specialized articles that govern dividends, interest, royalties, and other specific income types. When income could technically fall under both Article 7 and a dedicated article, the dedicated article controls.¹ This prevents the broader business profits rules from overriding the specific withholding rates treaty negotiators agreed on for investment-type income.

The exception is income from assets effectively connected to the permanent establishment. If a branch holds a bank account that earns interest as part of its daily operations, that interest is swept into the PE’s business profits and taxed under Article 7 rather than the interest article. The same logic applies to dividends from shares held as trading stock or royalties from intellectual property the PE actively exploits. What matters is whether the income-producing asset is functionally tied to the PE’s business or sits outside it as a passive investment.

How the UN Model Differs

The OECD Model is not the only treaty template. The United Nations Model, used more often in treaties involving developing countries, takes a broader approach through what is known as the “force of attraction” rule.

Under the OECD Model, a host country can tax only profits directly attributable to the permanent establishment. The UN Model goes further. If a company has a PE in a country, that country can also tax profits from direct sales of the same or similar goods, and from similar business activities, even if those transactions bypass the PE entirely.⁷ So if a local branch sells electronics and the head office also ships electronics directly to customers in the same country, the host country can tax both sets of profits. Companies working under UN-based treaties need to track not just what flows through their local branch but what the head office does directly in that market.

The Digital Economy and Pillar One

Article 7’s reliance on physical presence has always been an awkward fit for businesses that generate revenue in countries where they have no offices, employees, or warehouses. A streaming platform or digital advertising company can earn billions from a market without anything resembling a traditional permanent establishment. This gap drove the OECD’s development of the Pillar One framework.

Amount A under Pillar One would reallocate a portion of excess profits from the largest multinationals to the countries where their customers and users are located, regardless of physical presence. It targets companies with global revenue above EUR 20 billion and profit margins above 10 percent, reallocating 25 percent of profits above that 10 percent threshold to market jurisdictions.⁸ A review seven years after implementation could lower the revenue threshold to EUR 10 billion.

Pillar One would operate through a Multilateral Convention that modifies existing bilateral treaties to the extent needed to implement Amount A, leaving the rest of each treaty in force. As of early 2025, the Inclusive Framework was still working to finalize the package, and the convention had not yet been opened for signature.⁹ Until Pillar One enters into force, Article 7’s permanent establishment requirement remains the governing standard for in-scope treaties.

Disclosing an Article 7 Position on a US Tax Return

A foreign enterprise that relies on Article 7 to exclude its business profits from US tax cannot just stay silent. US law requires taxpayers to disclose any return position where a treaty overrides or modifies domestic tax rules.¹⁰ In practice, that means filing Form 8833, Treaty-Based Return Position Disclosure, as an attachment to the appropriate return.¹¹

The form attaches to whichever return applies: Form 1040-NR for nonresident individuals, Form 1120-F for foreign corporations, or Form 1042 for withholding agents. A separate Form 8833 is required for each distinct treaty-based position taken in a given year, though payments of the same type from the same source can be grouped on a single form.¹²

Skipping the disclosure is expensive. The penalty is $1,000 per failure for most taxpayers and $10,000 per failure for C corporations, on top of any other consequences.¹³ Treasury can waive the penalty for reasonable cause and good faith, but counting on that waiver is not a plan.

Resolving Article 7 Disputes

When two countries disagree about how Article 7 applies, the taxpayer caught between them can invoke the Mutual Agreement Procedure under Article 25 of the OECD Model. It is a government-to-government negotiation designed to resolve taxation that conflicts with the treaty.

To start, you present your case to the competent authority of your country of residence within three years of first being notified of the problematic taxation. Notification typically means the date of the assessment, though in some cases you can file preemptively if non-treaty-compliant taxation is clearly imminent.¹⁴ The three-year window is a minimum; individual treaties may allow longer.

Once initiated, the two competent authorities negotiate directly. Your role as the taxpayer is largely limited to providing information. The authorities are obligated to try to reach an agreement, but they are not required to succeed. If they fail to resolve the case within two years of receiving all necessary information, the OECD Model provides for mandatory binding arbitration at the taxpayer’s request, as long as no court or tribunal in either country has already decided the issue. Not every treaty includes this arbitration backstop, so check the specific treaty that applies to your situation.
