Singapore and Hainan appear on the same shortlist surprisingly often, usually when a company knows it wants an Asian base but has not yet decided whether it needs to be inside mainland China.
That is the decision worth making first. Singapore is a sovereign jurisdiction and a natural regional headquarters. Hainan is a province of mainland China with a Free Trade Port framework. They are not substitutes, and comparing their corporate tax rates before settling the operating question tends to produce a confident decision for the wrong reason.
Start with where the business will be performed
The useful test is not where you would prefer to be based. It is where the work happens and where the customers are.
Choose a mainland entity in Hainan when the business will contract under mainland law, employ staff in China, issue fapiao to mainland customers, collect RMB revenue from mainland clients, or hold a licence for a regulated mainland activity.
Choose Singapore when the business serves Southeast Asia or global markets, needs a regional holding or management base, and does not require a mainland operating presence.
Choose both when the group needs a regional headquarters and a mainland operating arm, which is a common outcome for companies with genuine China revenue.
A Singapore company cannot invoice mainland customers with fapiao, cannot employ mainland staff directly, and cannot hold a mainland business licence. If any of those are required, the Singapore entity is a complement to a mainland company rather than an alternative.
Side-by-side comparison
| Decision point | Hainan | Singapore |
|---|---|---|
| Best suited for | Operating and selling inside mainland China | Southeast Asia or global headquarters |
| Legal system | Mainland Chinese law | Singapore law |
| Mainland operating entity | Yes | No, a separate China entity is normally required |
| Corporate tax anchor | 25% standard; 15% for qualifying encouraged-industry enterprises with substantive operations | 17% headline corporate income tax rate |
| Issue fapiao to mainland customers | Yes | No |
| Employ mainland staff directly | Yes | No |
| Capital movement | Managed through the mainland foreign-exchange framework | Generally unrestricted |
| Free Trade Port policies | Direct eligibility assessment | Only through a qualifying Hainan entity |
| Typical language of compliance | Chinese | English |
Reading the tax comparison honestly
Comparing 15% against Singapore's 17% headline rate looks like a narrow win for Hainan. Both numbers need qualification.
Hainan's 15% rate is conditional and must be earned each year. The company's main business has to fall within an applicable encouraged-industry catalogue, that business must generate more than 60% of revenue, and the company must operate substantively in Hainan, assessed on real staff, premises, management and activity. Fail a test in a given year and the standard 25% rate applies for that year. Registration in Hainan does not create eligibility.
Singapore's effective rate is often below the headline. Singapore operates various exemption and rebate schemes that can reduce the effective rate, particularly for newer and smaller companies, subject to the applicable conditions. Comparing a conditional 15% against an unadjusted 17% overstates the gap.
Neither comparison is complete without distribution. Profits leaving a mainland entity to an overseas shareholder attract mainland withholding tax, subject to any applicable treaty arrangement. Singapore's treatment of distributions to shareholders is different. Compare the cost of getting cash to the shareholder, not only the tax on operating profit.
Substance requirements in both places
Both jurisdictions expect the entity to be real, and both have moved further in that direction rather than less.
In Hainan, substantive operation is the gate to the preferential tax rate. It is tested on people, premises, accounting, management and actual business activity in Hainan. This is the requirement that most often surprises companies who expected a registered address to be sufficient.
In Singapore, tax residence and access to treaty benefits turn on management and control being exercised in Singapore, and the compliance framework expects a genuine local presence appropriate to the activity.
A shell in either location is a liability. Budget for the substance the tax position requires.
Setup and ongoing compliance
Singapore is the lighter and faster incorporation, and the entire compliance framework operates in English. A Singapore company needs annual returns, financial statements prepared under the applicable standards, and annual tax filings. Audit requirements depend on whether the company meets the small-company criteria.
Hainan requires more front-loaded work. Shareholder documents typically need certification, by apostille where the issuing country is covered by the Apostille Convention or by consular legalisation otherwise. The business scope must reflect the real activity. After the licence, the company still needs seals, tax registration, invoicing setup, a bank account and foreign direct investment information registration through a bank.
Ongoing, a Hainan company files monthly and periodically, maintains statutory books in Chinese, completes the annual corporate income tax reconciliation and files the annual report for foreign-invested enterprises. Where the preferential rate is claimed, the supporting evidence must be maintained throughout the year.
The two-entity structure
For groups with real China revenue and a wider Asian footprint, a Singapore company holding or working alongside a Hainan operating entity is a reasonable structure.
What it achieves: a familiar regional base for management, investors and non-China contracts, plus a mainland entity that can trade, hire and invoice in China.
What it does not achieve: Singapore ownership does not confer mainland tax benefits on the Hainan entity, and it does not remove withholding on distributions from the mainland. Each entity's tax position rests on its own facts.
Two entities also mean two sets of accounts, two filing calendars and intercompany arrangements that need to be documented and priced on arm's length terms. Only take on that overhead if both entities have work to do.
Questions to settle before choosing
- Where are the customers, and will they require fapiao?
- Where will the staff who generate the profit actually work?
- Does the activity need a mainland licence?
- If Hainan's 15% rate is part of the case, which catalogue entry applies and can the 60% revenue test be met?
- What substance is each jurisdiction's tax position going to require, and is that budgeted?
- How will profits reach the shareholders, and what is the tax cost of that route?
If the answers put the business inside mainland China, compare Hainan with other mainland locations. If they put it outside, compare Singapore with other regional bases. If they genuinely straddle both, plan for two entities and price the overhead honestly.
