Tax-Free on Overseas Profits: How Hainan's Foreign-Source Income Exemption Works, and What It Means for Your Holding Structure

Most operators who've looked at Hainan know about the 15% corporate income tax rate. Fewer have worked through what happens when profits flow back from an overseas subsidiary. In most jurisdictions, that repatriation triggers a top-up tax, the difference between what you paid abroad and what your home jurisdiction charges. In Hainan, for qualifying enterprises, that top-up doesn't apply. The overseas profit comes back clean.

This is one of the more consequential and least-discussed advantages of the Hainan FTP structure. Here's how it works.

The policy in plain terms

Enterprises registered in the Hainan Free Trade Port that derive income from new overseas direct investments are exempt from corporate income tax on that income, provided the investment was made after the qualifying date, falls within the approved industry categories, and meets the structural requirements for what counts as direct investment income.

The operative word is new. Existing overseas investments at the time of Hainan registration don't qualify. The exemption applies to incremental outbound investment made from a Hainan-registered entity going forward.

Three conditions to clear

1. Timing of new investments

The investment must be made after the enterprise is established in Hainan and after the qualifying date set by the policy. Pre-existing overseas holdings don't receive the exemption, only investments initiated from the Hainan entity.

2. The business must appear in the preferential catalogue

Your principal business must fall within the Catalogue of Preferential Corporate Income Tax Policies for Tourism, Modern Services, and High-Tech Industries in the Hainan Free Trade Port. As with the 30% value-added rule, the 60% revenue threshold applies: income from your qualifying main business must account for more than 60% of total enterprise income.

3. The income must qualify as direct investment income

Not all overseas income is covered. The policy specifies two eligible income types:

• Operating profits from newly established overseas branches
• Dividend income from overseas subsidiaries where your ownership stake exceeds 20%, corresponding to the newly added investment

There is one additional condition on the overseas entity itself: the statutory corporate income tax rate in the country or region of investment must be not less than 5%. Investments into zero-tax jurisdictions don't qualify.

What counts as direct investment

Four forms of outbound investment are recognised:

1. Establishing a new branch overseas
2. Establishing a new enterprise overseas
3. Increasing capital or expanding equity in an existing overseas enterprise
4. Acquiring equity in an overseas enterprise

The third and fourth forms are particularly useful. If you already have an overseas entity and a Hainan parent subsequently increases its stake, as in Case 3 below, the exemption applies to the income attributable to the increased stake, not to the pre-existing holding.

How to claim it

The mechanism is self-assessment: you calculate the exemption, declare it in your annual corporate income tax filing, and retain documentation for inspection. There's no pre-approval process.

For resident enterprises, this is reported in Form A108010 (columns 19–26), under "New Overseas Direct Investment Income of Hainan Free Trade Port Enterprises."

For non-resident enterprise institutions, it's reported in Form F200 (line 5 and subordinate lines 6–10), using exemption nature code 04039907.

Filing is handled through the Electronic Taxation Bureau: I want to do tax → Tax Declaration and Payment → Regular Declaration.

Three cases that show the actual numbers

The policy authority has published three worked examples. They're worth reading carefully, the tax savings are not trivial.

Case 1: Culture & Communications company, Sanya

A tourism enterprise registered in Sanya in 2020 established a wholly owned subsidiary in Hong Kong in March 2022. The Hong Kong subsidiary earned RMB 500 million in net profit in 2022, paying 16.5% corporate income tax in Hong Kong (RMB 82.5 million).

When the after-tax profit was repatriated to the Hainan parent in 2023, a standard Chinese entity outside a preferential zone would have owed an additional 8.5%, the top-up between Hong Kong's 16.5% and China's standard 25% rate. That would have been RMB 42.5 million.

Under the Hainan exemption: RMB 42.5 million saved on a single repatriation.

Case 2: Cold Chain Logistics company, Yangpu

A modern services enterprise registered in Yangpu in 2020 acquired a wholly owned Hong Kong logistics subsidiary in January 2022. The subsidiary earned RMB 100 million in net profit in 2022 at 16.5% Hong Kong tax.

Standard top-up tax on repatriation: RMB 8.5 million. Under the Hainan exemption: RMB 8.5 million saved.

Case 3: Energy Technology company, Chengmai

This case illustrates the partial exemption when an existing stake is increased. A high-tech enterprise registered in Chengmai in 2021 raised its shareholding in a Hong Kong company from 10% to 30% in January 2022. The Hong Kong company earned RMB 10 million in profit in 2022, distributing RMB 3 million to shareholders in 2023.

The dividend income attributable to the increased 20% stake: RMB 2 million (calculated as 20%/30% × RMB 3 million). The remaining RMB 1 million, attributable to the pre-existing 10%, remains taxable.

Standard top-up on the full RMB 3 million: RMB 255,000. Under the Hainan exemption, only RMB 85,000 is owed (8.5% on the non-exempt RMB 1 million). Tax reduced by RMB 170,000 — and the principle scales linearly with the size of the investment.

What this means structurally

For operators currently using Hong Kong or Singapore as their holding jurisdiction for Asia-Pacific investments, the Hainan structure introduces a different calculus. The question isn't simply "what's the headline tax rate", it's "what happens when profits flow back up the chain."

A Hainan entity holding overseas subsidiaries in jurisdictions above the 5% threshold pays 15% corporate tax on its domestic Hainan income and zero top-up on qualifying repatriated overseas profits. The combination is worth modelling against your current structure.

The constraint, again, is the 60% revenue threshold from encouraged industry activities. This is a serious operating requirement, not a box-ticking exercise. But for businesses whose core activity already falls within tourism, modern services, or high-tech, and who have or plan overseas subsidiaries, the exemption materially changes the economics of where to locate the holding entity.
