Direct answer: Under China's double tax treaties, a foreign company most often creates a Chinese permanent establishment in four ways: maintaining a fixed place of business in China, sending staff to perform services in China for more than 183 days within a rolling 12-month period (the exact test varies by treaty), running a construction or installation project beyond the treaty duration threshold (commonly 6 or 12 months), or doing business through a person in China who habitually concludes contracts on its behalf. Once a PE exists, China taxes attributable profits at the 25% CIT rate and can assess VAT and surcharges as well.
1. Why PE risk is easy to trigger by accident
PE exposure rarely comes from a deliberate decision. It accumulates through ordinary operations: engineers flying in repeatedly for commissioning work, a sales manager closing deals from a Shanghai co-working desk, a distributor that negotiates prices and signs order forms in the foreign company's name, or an installation project that overruns its schedule. Each pattern is unremarkable on its own; together they can cross a treaty threshold.
The financial consequence is retrospective. If the tax bureau concludes a PE existed for the past several years, it can assess CIT on deemed or actual attributable profits for all open years, plus late-payment surcharges of 0.05% per day and potential penalties. The domestic-law starting point is also unfavourable: under the Enterprise Income Tax Law, a non-resident with an "establishment or place" in China is taxed on China-connected income, and treaties then define how far that reaches.
2. The four PE patterns that matter in practice
| PE type | Typical treaty test | Common accidental trigger |
|---|---|---|
| Fixed place PE | A place of business at the company's disposal — office, branch, workshop, or even a dedicated desk — used with a degree of permanence | Staff working long-term from a customer site, a serviced office or a local partner's premises |
| Service PE | Services performed in China by the foreign company's personnel exceeding a day-count, frequently 183 days within any 12-month period (treaty-specific) | Rotating engineers, consultants or project teams whose combined presence adds up across individuals |
| Construction / installation PE | A building site or installation project lasting beyond a duration threshold — commonly 6 or 12 months depending on the treaty | Project overruns, supervisory activities, and related contracts being aggregated |
| Dependent agent PE | A person in China habitually concludes contracts, or habitually plays the principal role leading to their conclusion, on behalf of the foreign company | Local sales agents, distributors or even employees of an affiliate who negotiate and finalise terms |
Note: Day-counts and duration thresholds are treaty-specific. China's treaties with different countries define service and construction PEs differently, and the counting method (days of presence, days of activity, aggregation of related projects) varies. The applicable treaty must be read directly for any live case.
3. What China taxes once a PE exists
A PE is taxed on the profits attributable to it — determined by transfer-pricing principles as if the PE were a separate enterprise. Where books are inadequate, bureaus may apply deemed-profit methods to the PE's China revenue. On top of CIT, the underlying activities usually attract VAT: on-site services and construction performed in China are China-taxable for VAT regardless of PE status, so the same fact pattern often creates two taxes at once.
There is also a compliance layer. A non-resident with a China PE is expected to register with the tax authorities and file CIT returns. Failure to register is itself penalised, and the foreign company's China customers can find their payments questioned when the counterparty's tax status is unclear — which is how many PE cases surface in the first place.
4. Patterns that raise — or lower — your risk
Higher risk
- Employees with business cards, titles or email signatures suggesting China-based roles for the foreign entity.
- Contracts negotiated and effectively finalised by a local person, even if signed abroad for form.
- Long or repeated on-site projects with rotating staff and no day-count tracking.
- Inventory held in China under the foreign company's control with local sales activity.
Lower risk (when genuinely structured)
- Truly independent local distributors who buy and resell in their own name at their own risk.
- Preparatory or auxiliary activities, such as market research or storage for display, which treaties generally carve out.
- Operating through a properly registered WFOE that earns an arm's-length return, converting open-ended PE exposure into a contained, compliant structure.
5. A practical PE risk-control routine
- Track person-days in China. Log every day every employee and contractor spends working in China, by project, and measure against the applicable treaty's service-PE threshold.
- Review contract-formation facts, not just signatures. Identify who actually negotiates and closes. If it is a person in China, assess dependent-agent exposure regardless of where the paper is signed.
- Watch project duration. Monitor construction and installation timelines against treaty thresholds, including related or consecutive contracts that bureaus may aggregate.
- Register before you are found. Where thresholds are crossed, voluntary registration and filing is materially cheaper than an assessed settlement with surcharges.
- Consider a WFOE when activity is recurring. Once China activity is continuous and revenue-bearing, a subsidiary usually costs less than the combined tax, VAT and risk overhead of a long-lived PE.
Caution: PE analysis turns on the specific treaty, the facts and current administrative practice, all of which differ by country pair and evolve over time. The thresholds in this article are common treaty patterns, not universal rules; obtain advice on the applicable treaty before relying on any day-count.

Frequently asked questions
1. What is a permanent establishment in China?
A taxable presence defined by China's tax treaties and domestic law: a fixed place of business, long-running services or construction activities, or a dependent agent in China. Once it exists, China can tax the profits attributable to that presence at the 25% CIT rate.
2. How many days in China trigger a service PE?
Many of China's treaties use a 183-day test within a rolling 12-month period for services performed by the foreign company's personnel, but the exact threshold and counting method vary by treaty. The applicable treaty text must be checked for any real case.
3. Can a local distributor create a PE for me?
A genuinely independent distributor buying and reselling in its own name normally does not. Risk arises when the "distributor" habitually negotiates or concludes contracts on your behalf, maintains your inventory, or acts under your detailed control — facts can override the contract label.
4. What taxes apply if a PE is found?
Corporate income tax at 25% on attributable profits (sometimes on a deemed-profit basis), plus VAT on the underlying China services, surcharges for late payment and potential penalties — assessed retrospectively for the open years.
5. Does having a WFOE eliminate PE risk?
A WFOE converts the parent's open-ended exposure into a contained, registered structure. The parent can still create its own PE through activities performed in China outside the WFOE — for example staff seconded without a proper service arrangement — so boundaries still need managing.
6. How do tax bureaus discover PEs?
Through customer payment records and withholding filings, customs and visa data, audit trails of Chinese counterparties, and information exchange under treaties. Long-running service projects are particularly visible because customers' records show who performed the work and where.
