How Mainland and Hong Kong Companies Should Divide Their Roles
Author: Junanda ConsultingReviewed by: Junanda Service Team2026-09-19
In cross-border trade, pairing a mainland China enterprise with a Hong Kong SAR company is a very common arrangement. It is in itself a compliant commercial structure. The problems usually arise where the division of roles is unclear: who signs the contract, who receives the money, who issues the invoice and who makes the customs declaration. Where the entities involved at each stage do not match, the arrangement leaves latent risk in account reviews and tax examinations. This article sets out the usual allocation of roles, the consistency principle, and the practices that carry high risk.
Common Structures and Each Entity's Role
The core of any structure design is to let each entity perform the functions that it is genuinely capable of performing.
| Stage |
Mainland company |
Hong Kong SAR company |
| Procurement and production |
Handles procurement, production and quality control |
Generally not involved in production |
| Domestic sales |
Handles domestic sales, channels and customer service |
Not involved |
| Employment |
Employs mainland staff and handles social insurance |
Employs staff in Hong Kong where needed |
| Entrepot trade |
May take part in the onshore stages |
Deals with overseas customers and handles the entrepot trade |
| Receipt and payment of foreign exchange |
Cross-border receipts and payments handled as required |
Collects payments from overseas customers and pays overseas suppliers |
| Liaison with overseas customers |
Depending on business needs |
The principal entity for this |
One basic principle applies: the entity should be located where the function takes place. The value of the Hong Kong SAR company lies in connecting overseas customers with overseas funds, not in acting as a pure payment channel.
Related-Party Pricing Must Be Explainable
The mainland company and the Hong Kong SAR company are related parties, so transaction pricing cannot be set arbitrarily. The following standards apply:
- Pricing should refer to comparable prices between independent third parties or to industry practice;
- It should be possible to explain the functions performed by each party, the assets used and the risks borne;
- Related-party and third-party transactions should be clearly distinguished in the accounts;
- Where the prescribed standard is reached, transfer pricing documentation of the corresponding level should be prepared under the current rules.
Common transfer pricing documentation includes the master file, the local file and the special issue file. The specific thresholds, levels and content requirements are subject to the latest official rules. What matters is not the documents themselves, but whether the transaction chain makes commercial sense.
The Consistency Principle: Four Questions That Must Match
This is the most important practical lesson. From signing to payment, a transaction should keep the same entities throughout:
- Who signs the contract: the contracting party is the transacting entity for that transaction;
- Who receives the money: the recipient matches the contracting party, with no collection by a third party;
- Who issues the invoice: the invoicing entity matches the contracting and receiving parties;
- Who makes the customs declaration: for the import and export of goods, the declarant matches the ownership of the goods and the flow of funds.
Where agency arrangements or back-to-back contracts are used for business reasons, the contract should set out each party's role and responsibilities clearly, and the complete business chain should be documented.
Profit Retention, Repatriation of Funds and Tax Residence
How the profits of the Hong Kong SAR company are used and repatriated needs a clear commercial logic:
- Retained in the Hong Kong SAR company for its own operating expenses, such as procurement, staff, office costs and overseas marketing;
- Distributed as dividends, following the procedures under mainland and the relevant tax rules;
- Paid as consideration for goods under a trading arrangement, supported by the corresponding contract and documents.
The determination of tax resident status deserves attention. If the effective management of the Hong Kong SAR company is located in the mainland, it may be treated as a tax resident of mainland China and may accordingly have onshore tax obligations. The arrangements between the two places contain provisions for eliminating double taxation, and the specific application should follow the current arrangements and the latest official positions.
Economic Substance, Offshore Exemption and Bank Due Diligence
Hong Kong SAR applies the territorial source principle: whether profits are taxable there depends on whether they arise in or are derived from Hong Kong SAR. Claiming offshore exemption requires the enterprise to be able to demonstrate that the business genuinely operates, and this usually involves:
- The Hong Kong SAR company having actual office premises and staff, or a reasonable outsourcing arrangement;
- The place where business is negotiated, contracts are signed and decisions are taken being traceable;
- Complete contracts, correspondence, documents and accounting records in support.
Note that claiming offshore exemption means providing the tax authority with sufficient evidence of the business; the burden of proof lies with the enterprise. The more solid the economic substance, the more defensible the claim.
Hong Kong SAR banks review accounts with increasing strictness, and both account opening and account maintenance focus on:
- The genuineness and sustainability of the company's business, including who its customers and suppliers are and what its transaction model is;
- The relevance of the background of the directors and shareholders to the business;
- Whether the flow of funds is consistent with the declared business model;
- Responding to the bank's customer due diligence (CDD) questionnaires and information update requests on a regular basis.
Retaining business documents is therefore not only a tax requirement but also the basis for keeping an account in normal use. Failing to respond to a bank's enquiries is a common reason for an account to be restricted.
High-Risk Practices and Day-to-Day Documentation
The following practices carry particularly high risk:
- Collecting foreign exchange through a shell: a Hong Kong SAR company with no staff, no premises and no real business that merely collects payments on behalf of others;
- Receiving company money into a personal account: mixing entities and making the source of funds difficult to explain;
- No genuine flow of goods: only funds and invoices, with no contracts, documents or records of transfer of title;
- Arbitrary pricing: related-party prices that clearly depart from the market with no explanation;
- Mismatched entities across documents: one entity signs the contract, another receives the money and a third makes the customs declaration.
What these practices have in common is that they make the whole transaction chain impossible to evidence. Once examined, they may bring not only additional tax and late payment charges but also consequences for bank accounts and credit standing.
Whether a structure holds up ultimately depends on whether a complete file can be produced. The following approach to document management is worth adopting.
File transaction by transaction. Open a separate file for each cross-border transaction, containing the contract or order, invoice, transport or delivery documents, evidence of receipt or payment of foreign exchange, and correspondence (emails and screenshots of messages). Use a consistent naming format, for example "transaction number - abbreviated customer name - date of signing", so that files are easy to locate.
Bind annually. At the end of the year, bind the files in transaction number order with a transaction summary sheet, so that they can be produced quickly during a review. The summary should include the transaction number, customer name, contract amount, amount received, date of receipt and the numbers of the corresponding documents.
Keep related-party transactions in a separate volume. File transactions between the mainland and Hong Kong SAR companies separately, with a pricing note and a functional and risk analysis, clearly separated from third-party transactions.
Retention period. The retention period for accounting vouchers, books and related contracts and documents follows the current rules. It is advisable to retain them for somewhat longer than the statutory minimum, in order to be able to respond to any retrospective examination.
Archive management may look like routine clerical work, but it is the easiest part of structural compliance both to strengthen and to see results from. A business with genuine operations will always have substantial files.
