Hainan Substantive Operation: What the Test Requires

Substantive operation is the requirement that decides whether a Hainan company actually gets the tax treatment it was set up for. It is also the requirement most often glossed over at the planning stage, because it is the one that costs money to satisfy.

The principle is straightforward. Hainan's preferential corporate income tax treatment is available to enterprises that genuinely operate in Hainan. A registered address is not operation. Registration in Hainan does not by itself change the company's tax rate from the 25% standard rate.

This guide explains what the test looks at, how it interacts with the other conditions, and what evidence a company should be building from its first month.

Where the requirement comes from

Hainan's 15% corporate income tax rate applies to qualifying encouraged-industry enterprises with substantive operations in Hainan. There are three conditions, and all must hold:

1. the main business falls within an applicable encouraged-industry catalogue;
2. that business generates more than 60% of total revenue; and
3. the enterprise operates substantively in Hainan.

The third condition exists to prevent registration-only arrangements. An enterprise that is registered in Hainan but managed and operated elsewhere is not what the policy is designed to support.

What the test examines

Substantive operation is assessed on the company's real situation rather than on a single document. In practice the assessment looks at whether the elements that make up a functioning business are actually located in Hainan.

Production and operation. Whether the company's actual business activity takes place in Hainan. For a service company this means where the work is performed; for a trading company, where the transactions are managed.

Personnel. Whether the company has staff in Hainan appropriate to its activity and revenue, and whether those people genuinely work there rather than appearing on a payroll list.

Accounts. Whether the accounting is maintained in Hainan, with the records supporting the company's revenue classification and operations.

Assets. Whether the assets the business uses are held and used in Hainan.

Management. Whether the institution that makes and executes decisions about the company's operations, personnel, accounts and assets is located in Hainan.

The management element deserves particular attention. A company whose operating decisions are all made elsewhere has difficulty establishing substantive operation regardless of how its other elements are arranged.

The staffing dimension

Staffing is where planning assumptions most often fall short.

The expectation is that people relevant to the company's operations are actually present and working in Hainan, over a meaningful part of the year rather than for a token period. A common practical reference point is whether staff are in Hainan for the greater part of the year, which is where the 183-day framing that circulates in discussion comes from.

Rather than treating any single number as a safe harbour, the useful question is different: would an examiner reviewing the company's payroll, social insurance records, work locations and actual output conclude that this business is run from Hainan?

If the honest answer is no, the tax position is not ready to be relied on, whatever the day count.

How the conditions interact

The three tests are cumulative and they are assessed for each tax year.

This has two consequences that catch companies out.

Qualifying once does not qualify you permanently. Eligibility is assessed year by year. A company that met the conditions in one year and not the next should not apply the preferential rate for the year in which it failed.

Passing two tests is not enough. An encouraged-industry company earning 80% of revenue from the catalogue activity but managed entirely from overseas has not met the conditions. Equally, a company with genuine Hainan operations whose main business falls outside the catalogue does not qualify on substance alone.

Building the evidence

Substantive operation is demonstrated by ordinary business records accumulated as the company operates, not by a document produced when a question arises.

The records worth maintaining from the start:

• employment contracts, payroll records and social insurance registrations showing staff in Hainan;
• premises documentation, such as a lease, together with evidence the space is used;
• accounting records maintained in Hainan, with revenue classified so the encouraged-industry proportion can be demonstrated;
• board and management records showing where decisions are made;
• contracts showing where the company's obligations are performed; and
• records of the assets used in the business and where they are located.

The test these records need to pass is consistency. The business scope on the licence, the contracts, the revenue classification in the books, the location of the people and the company's actual activity should all describe the same business.

What this means for cost planning

This is the practical point that changes investment cases.

Satisfying substantive operation means real premises, real staff and real management presence in Hainan. Those are recurring operating costs. If a financial model applies a 15% rate while assuming a registered address and no local team, the model is internally inconsistent.

The honest way to evaluate Hainan is to price the substance first, then apply the tax rate to the resulting business. For companies with a genuine reason to operate in Hainan, the arithmetic often works well. For companies seeking only a rate, it usually does not.

Questions to answer before relying on the rate

1. Which exact catalogue entry covers the main business?
2. How will more than 60% of revenue be shown to come from that activity?
3. Who will work in Hainan, in what roles, and for how much of the year?
4. Where will operating decisions actually be made?
5. Where are the company's records kept, and who maintains them?
6. Where are the company's contracts performed?
7. Is the cost of that presence included in the financial plan?

If an adviser cannot walk through these with you, the tax estimate is not yet usable.
