Many sellers who do cross-border e-commerce have heard this phrase before:
“You're definitely at a disadvantage tax-wise when you use a mainland company for everything.”
Then went to register a Hong Kong company, and after registering found -
How do the two companies work together? Where does the money come in, where does it go out, and how does it end? Where do the profits go? What about taxes?
All unknown.
Today's article, from the principle of the “two-major structure” this matter from the hands-on clear.

Let's look at a typical problem scenario first:
You use a mainland company for Amazon, and all payments go back to the mainland company's public account. That's when you find out:
The dual-principle structure addresses the core problem: keeping money in the right place and taking the compliant path back.
The most commonly used two-body structure for cross-border sellers:
Mainland companies (procurement + export customs clearance)
↓ Exports of goods
Overseas platforms (Amazon/TikTok/NOON, etc.)
↓ Sales returns (USD/EUR/HKD)
Hong Kong company (taking on overseas income + multi-currency collection)
↓ Compliance settlement/profit repatriation
Mainland companies (repatriation of funds + domestic tax returns)
Mainland companies are responsible:
Hong Kong companies are responsible:
The logic of the two sides is that goods are exported from the Mainland and money is collected from overseas, and each side does what it does best.

This is the most asked and most common question that sellers get wrong.
There are three main legal routes for Hong Kong companies to return their profits to the Mainland:
| Payback path | operating method | Applicable Scenarios | Key premises |
|---|---|---|---|
| Trade settlement | Payment of purchase price by Hong Kong company to Mainland company | Goods exported from a Mainland company to a Hong Kong company | Real trade background + export declaration |
| Payment of service fees | Payment of service fees (operation/design/technology) by Hong Kong companies to Mainland companies | Mainland companies providing services to Hong Kong companies | With real service content + service contract |
| Profit sharing repatriation | Distribution of dividends from Hong Kong companies to Mainland shareholders | Shareholders are Mainland enterprises or individuals | ODI filing needs to be completed |
⚠️ Three common mistakes:
Pit 1: Mixed business of the two companies and no separation of accounts
Some sellers think that “it's my company anyway”, and the mainland company directly collects the payment from the Hong Kong company, or the Hong Kong company pays the suppliers for the mainland company.
This is called “mixed personality” in the law, once the dispute, the legal responsibility of the two companies can not be divided, but also be recognized by the tax bureau as anomalous related transactions.
The right approach: Each of the two companies keeps separate accounts, and money transactions must be contracted, documented and reasonably priced.
Pit 2: Unreasonable pricing, recognized as profit shifting
What is the purchase price for goods purchased by a Hong Kong company from a Mainland company?
The right approach: Transfer pricing needs to comply with the “independent transaction principle”, i.e. the transaction price between the two companies should be close to the market price. We can help you analyze the transfer pricing and find a reasonable range.
Pit 3: Only registered a Hong Kong company without building a complete link
Many sellers registered Hong Kong companies, opened an account, and then ...... there is no then. Mainland companies still collect money directly from the platform, the Hong Kong company has become a setup, and every year you have to pay the annual review fee.
The right approach: Registering a Hong Kong company is only the first step, but also need to complete: platform collection account switching → business contract re-signing → capital path re-planning → both sides of the accounts system construction.

| Seller Type | whether sth. is suitable | rationale |
|---|---|---|
| Multi-platform (Amazon + TikTok + independent sites) | ✅ well suited | Strong demand for multi-currency collections and complex funding chain |
| Single platform but $50,000+ in monthly sales | ✅ suitability | There is plenty of room for tax planning, and the amount of money is worth putting up the structure |
| We're just starting out, and we're selling less than $10,000 a month. | ⚠️ It can wait. | Maintenance Costs > Tax Savings |
| Purely domestic e-commerce | ❌ Not suitable | No cross-border scenarios |
