Permanent Establishment (PE) Risk: What Happens When Head-Office Staff Sell in the U.S.

/ Blog (EN), International Tax & Treaties / By

“If we don’t set up a U.S. subsidiary and just have our Japan head office staff sell on business trips, we won’t owe U.S. corporate tax.” That understanding is half right and half dangerous. Under the US-Japan tax treaty, a Japanese company’s business profits aren’t taxed in the U.S. unless the company has a permanent establishment (PE) there. But depending on what your employees actually do, a PE can be found even without an office, triggering retroactive filing and tax obligations. This article explains how a PE is determined and which activities to watch when head-office staff sell in the U.S.

What Is a PE? Three Types

Article 5 of the US-Japan tax treaty defines a PE in roughly three ways:

  • Fixed place of business: a branch, office, factory, or workshop — a “fixed place” through which business is carried on. Beyond an office leased in the company’s name, a dedicated coworking desk or an employee’s home used continuously as a base of operations can qualify.
  • Construction project: a building site or installation project that lasts more than 12 months.
  • Dependent agent: a person (employee or agent) acting on behalf of the Japanese company who has, and habitually exercises, authority to conclude contracts in the company’s name. That person’s activity itself is treated as a PE.

What Doesn’t Create a PE: Preparatory and Auxiliary Activities

The treaty carves out places used solely for activities such as:

  • Storing, displaying, or delivering goods
  • Purchasing goods or collecting information
  • Advertising, market research, and other preparatory or auxiliary activities

Activities carried out by an independent agent (a broker or general commission agent) in the ordinary course of its business also don’t create a PE. But an agent that works substantially exclusively for the Japanese company under its direction may not be treated as independent.

Where the Risk Lies When Head-Office Staff Sell in the U.S.

The dependent-agent PE is the biggest risk. Typical fact patterns include:

  • An employee stationed in the U.S. (or a locally hired sales rep) negotiates price, quantity, and terms with customers, and head-office approval is a formality — the contract is effectively concluded in the U.S.
  • An employee uses a U.S. home or rented office continuously as a base, with that address on business cards and contracts
  • A U.S. distributor works exclusively under the Japanese company’s direction and handles contract execution on its behalf

Conversely, if employees limit themselves to introducing customers, explaining products, and relaying quotes, and contracting authority genuinely rests with the head office in Japan (which actually reviews and signs), PE risk drops substantially. In practice, keep contracting authority clearly in Japan and make sure job descriptions and actual conduct match.

Consequences If a PE Is Found

  • Business profits attributable to the PE are subject to the 21% federal corporate tax, and Form 1120-F must be filed
  • Branch Profits Tax (0-5% under the treaty) applies to the deemed remittance of after-tax profits
  • If no return is filed within 18 months of the due date, deductions can be disallowed, leaving gross receipts subject to tax
  • State taxes are not governed by the treaty; states apply their own nexus standards, so state filing and tax obligations can arise regardless of PE status

Frequently Asked Questions

Q: We can’t tell whether our U.S. activities amount to a PE. Is it fine to do nothing?

A: When it’s a close call, consider filing Form 1120-F as a “protective return.” You take the position that you have no U.S. taxable income while still filing, which preserves your right to claim deductions if a PE is later found. See our separate article on Form 1120-F and protective returns.

Q: If we have a U.S. subsidiary, is the parent free of PE risk?

A: A subsidiary by itself doesn’t constitute the parent’s PE. But if subsidiary employees effectively act as the parent’s agents and conclude contracts in the parent’s name, or parent employees run the parent’s business out of the subsidiary’s office, the parent can have its own PE separate from the subsidiary.

Summary

Even without an office, a Japanese company can have a dependent-agent PE if its employees habitually exercise contracting authority in the U.S., bringing U.S. corporate tax and filing obligations with it. Keep U.S. activities preparatory or auxiliary, keep contracting authority clearly in Japan, and file a protective return when the answer is unclear — those three principles should guide how you structure U.S. sales activity.
