Permanent establishment is one of those tax concepts that sounds theoretical until it isn’t. A foreign company that sends employees to China for extended periods, maintains a project office, or works through a dependent agent may discover that it has inadvertently created a Chinese taxable presence — and the tax bill that comes with it isn’t limited to the profits from the Chinese activity.
Here’s what foreign companies need to understand about permanent establishment risk in practice, particularly in the Greater Bay Area where cross-border movement of people and projects has become routine.
What Actually Creates a PE in China
Chinese tax law, following the OECD Model Convention framework that underpins most of China’s double taxation treaties, recognizes several types of permanent establishment. A fixed place of business is the most straightforward — an office, a factory, a workshop, or a construction site that lasts more than a certain period typically six to twelve months depending on the treaty.
A construction or installation project becomes a PE if it exceeds the time threshold in the relevant treaty. Most of China’s treaties set the threshold at six or twelve months. A project running two or three months over the threshold can create tax liability for years of activity, not just the over-threshold period.
A service PE can arise when a foreign company provides services in China through its employees for more than 183 days in any twelve-month period. This catches companies that send technical specialists, engineers, or consultants to work on projects for Chinese clients. If the same or connected projects keep the personnel in China for more than the threshold, the activities can constitute a PE even though no fixed office exists.
An agency PE arises when a person in China habitually exercises authority to conclude contracts on behalf of the foreign company. This is the one that catches companies using sales representatives, distributors, or even affiliated entities to conduct business in China. If the representative negotiates the material terms of contracts and the foreign company routinely accepts them without material modification, the representative may qualify as a dependent agent and create a PE.
The Profit Attribution Problem
Once a PE exists, China can tax the profits attributable to it — and “attributable” is where the disagreements happen. Chinese tax authorities apply a functionally separate entity approach, treating the PE as if it were an independent enterprise dealing with the foreign head office at arm’s length.
This means the PE’s taxable profits are not limited to the revenue from Chinese customers that the PE directly generated. The PE must be attributed an arm’s length share of the profits from the overall value chain. If the foreign company’s products incorporate significant IP developed at headquarters, some of the profit from Chinese sales may be attributed to the IP rather than the PE. But if the PE itself performs valuable functions — technical support, adaptation, quality control — more profit may be attributed to China.
The practical result is that the PE’s taxable profit is often substantially more than what the foreign company expected. A company that thought it had only a modest service income in China may find itself facing a reassessment that attributes a share of its global margin on Chinese sales to the PE.
Secondment Arrangements
Sending employees to a Chinese subsidiary or joint venture under a secondment arrangement is one of the highest-risk activities for unintended PE creation. If the secondees remain under the direction and control of the foreign parent, work primarily for the parent’s benefit, and the parent bears their economic cost, the arrangement may create a PE of the foreign parent in China.
The Chinese tax authorities have been focused on secondment arrangements in recent years. They look at who instructs the secondees day to day, who evaluates their performance, who bears the financial risk of their activities, and whose business they primarily serve. An arrangement structured as a cost recharge from the parent to the subsidiary doesn’t automatically avoid PE characterization if the substance of the arrangement is that the parent is operating in China through its employees.
Pre-Immersion Planning
Companies sending personnel to China should plan for PE risk before the first employee boards the plane. The number of days spent in China should be tracked from day one, not retrospectively when someone asks the question. Connected projects should be identified and their combined duration calculated.
The legal form of the China presence matters. Operating through a properly incorporated WFOE, as opposed to a representative office or an informal arrangement, generally provides clarity about the tax presence because the WFOE is the taxpayer and the foreign parent’s exposure is limited to its equity investment.
Contract structuring can help manage PE risk where the foreign company has a choice. A contract that is negotiated and concluded outside China, with the China office providing only preparatory or auxiliary support, may avoid PE characterization under the dependent agent rules, if properly documented and consistent with the actual facts.
Tax Treaty Protection
The starting point for any PE analysis is the applicable double taxation treaty between China and the foreign company’s country of residence. Some treaties provide more favorable thresholds — longer construction PE periods, narrower service PE provisions, or higher thresholds for dependent agent characterization.
But treaty protection isn’t automatic. The foreign company must be able to demonstrate that it is the beneficial owner of the income and that it qualifies for treaty benefits under the limitation on benefits provisions that China has been incorporating into its more recent treaties. A letterbox company with no substance in the treaty jurisdiction won’t pass scrutiny.
