Substantive Operation in the Hainan FTP: A Four-Element Test Where One Failure Is Fatal
The 15% corporate income tax rate is conditional on substantive operation, and the test has four elements that must all be satisfied in Hainan. Missing any one of them disqualifies the enterprise entirely.

Every enterprise claiming the Hainan Free Trade Port's 15% corporate income tax rate signs a self-assessment undertaking on substantive operation at annual reconciliation. It is a short form. What it commits the enterprise to is not short at all, and the most common misunderstanding about it is structural rather than clerical: companies treat substantive operation as a threshold they can mostly meet, when the test as written is one they must entirely meet.
The relief and the condition arrive in the same instrument
The reduced rate comes from the Notice on Enterprise Income Tax Preferential Policies for the Hainan Free Trade Port (关于海南自由贸易港 企业所得税优惠政策的通知, 财税〔2020〕31号), issued jointly by the Ministry of Finance and the State Taxation Administration on 23 June 2020. Two conditions sit in the same sentence as the rate. The enterprise must conduct a business listed in the Hainan FTP encouraged industries catalogue as its main business, and that main business must account for more than 60% of total revenue. And it must be in substantive operation in the Free Trade Port. The notice is explicit that an enterprise failing the substantive operation condition may not enjoy the preference at all.
The dates matter, because the notice as originally drafted ran only to 31 December 2024. It was continued by 财税〔2025〕3号 of 12 February 2025 to 31 December 2027, and the corresponding substantive operation rules were continued by a joint announcement of the Hainan Tax Service, the Hainan Provincial Department of Finance and the Hainan Provincial Administration for Market Regulation (2025年第3号) on 14 August 2025. Anyone still working from the face text of the 2020 notice is reading an expired end date.

Production, people, books, property — and the word 'and'
Substantive operation means that the enterprise's actual management body is established in the Free Trade Port and exercises substantive and comprehensive management and control over the enterprise's production and operation, personnel, accounts and property. Guidance from the Hainan authorities puts the consequence plainly: the four elements must all be in the Free Trade Port, and if any single one of them is not, the enterprise does not have substantive operation. There is no weighing, no partial credit, and no averaging across elements.
- Production and operation — the enterprise holds fixed premises and the equipment and facilities its business actually needs, and either its principal place of business is in the Free Trade Port or the body exercising substantive comprehensive management and control over production and operation is. Contracts are concluded in the enterprise's own name.
- Personnel — employees sufficient for the business actually work in the Free Trade Port, and their wages and salaries are paid through a bank account the enterprise has opened there.
- Accounts — accounting vouchers, accounting books and financial statements are kept in the Free Trade Port, and both the basic deposit account and the account through which main-business settlement runs are opened there.
- Property — the assets the enterprise's claimed activity depends on are held in the Free Trade Port rather than sitting with an affiliate elsewhere.
The headcount condition is the one that catches lean structures
The personnel element carries a specific residence requirement that surprises groups used to running a Hainan entity on a skeleton. Depending on the enterprise's scale and workforce, guidance sets a range of at least three and up to thirty employees who must each have resided in the Free Trade Port for a cumulative 183 days within a single tax year. This is a residence test on named individuals, not a payroll count. An entity carrying twenty people on its payroll, none of whom spend half the year on the island, has a headcount that looks comfortable and a personnel element that fails.
Two patterns the rules name as disqualifying on sight
Rather than leaving the assessment entirely open, the guidance identifies two situations that are treated as not meeting substantive operation without further argument. The first is an entity with no production or operation function of its own, existing only to handle financial settlement, tax declaration and invoice issuance for business that is really being done in the mainland. The second is an entity whose registered address does not match where it actually operates, where it cannot be reached, or where on being reached it cannot produce its actual operating address. Both are recognisable from outside the company, which is precisely why they were written down.
Self-assessed at filing, verified afterwards
The administrative model is self-determination, declaration by undertaking, and post-hoc verification. The enterprise assesses its own position, completes a substantive operation self-assessment undertaking form at annual corporate income tax reconciliation, and takes the preference. Nobody approves it at the point of filing. The verification happens later, against the year that has already closed — which means the evidence either accumulated during that year or does not exist. This is the single most important practical feature of the regime and the one most often misread as leniency.
Nothing is approved when the undertaking is signed. The review comes afterwards, against a year that can no longer be changed.
What the file needs to contain before anyone asks for it
- A lease and premises evidence consistent with an office that is actually occupied and equipped for the claimed activity.
- A record of where contracts were negotiated and executed, in the entity's own name rather than a parent's.
- Payroll run through a Free Trade Port bank account, with day-count records for the individuals relied on to meet the residence requirement.
- Accounting vouchers, books and statements physically kept on the island, with the basic deposit account and main settlement account opened locally.
- Board and management records showing decisions taken by the people the entity says manage it, in the place it says they manage it from.
- A revenue analysis demonstrating that catalogue main business exceeds 60% of total revenue for the year being claimed.
Treating the condition as a design input, not a filing question
The reason we assess substantive operation at structuring rather than at reconciliation is that every element of the test is cheap to satisfy when an entity is being designed and expensive to retrofit once it is operating. Where a group's Hainan entity is genuinely lean, the honest output is often that the 15% rate is not reachable at the headcount the group wants to run, and that finding is worth more in month one than in the month a verification letter arrives. Our substantive operation compliance work builds and maintains the evidence file against each of the four elements, and where eligibility itself is the open question, it runs alongside Encouraged Industry Eligibility rather than after it.
This is general commentary on published policy, not entity-specific tax advice, and it does not substitute for an assessment of a particular enterprise's facts.
