A Must-Read for Investing in a Hong Kong Company Do You Understand the Complexity of Filing Requirements?

In the context of global economic integration, an increasing number of mainland Chinese companies are choosing to go global by establishing or acquiring overseas entities to expand into international markets. As one of the world's leading financial centers, Hong Kong-thanks to its low tax rates, robust legal system, and open, transparent business environment-has become a top destination for many investors.

However, many businesses discover during implementation that while setting up a Hong Kong company may seem straightforward, completing a fully compliant investment process-especially when it involves cross-border capital flows-often requires navigating a crucial step filing for regulatory filing.

1. What is Filing, and Why Is It So Important?

Filing refers to the process by which domestic institutions or individuals must complete approval or registration procedures with relevant authorities before making outbound investments, as required by national laws and regulations. For most mainland investors, investing in a Hong Kong company falls under the category of Outward Direct Investment ODI, which mandates compliance with the Administrative Measures for Overseas Investment and other related rules.

Filing is not only a prerequisite for legal and compliant operations but also serves as the foundation for subsequent steps such as capital outflows, profit repatriation, and tax planning. Failure to complete the filing process can result in delays in fund transfers at best, and regulatory penalties or disruptions to overseas business expansion at worst.

2. The Filing Process Is Complex-Details Determine Success or Failure

Although the filing system has a clear legal basis, in practice, it often presents numerous challenges and uncertainties. For instance, different industries and investment purposes may be subject to varying policy requirements. Additionally, local commerce departments and development and reform commissions may exercise discretion in their review standards.

Take a 2025 media-reported case as an example a Zhejiang-based tech company planned to establish a research center in Hong Kong to connect with the European and U.S. markets. Without fully understanding the filing requirements, the company directly transferred funds overseas, only to be halted by the State Administration of Foreign Exchange and required to make up the necessary procedures. This not only delayed the project timeline but also impacted the company’s cash flow.

This illustrates that filing is not merely a formality-it is a critical step that requires early planning, thorough preparation of documents, and careful structuring of the investment model. Companies operating in sectors such as high-tech, culture, and real estate are especially likely to face heightened scrutiny during the filing process.

3. Recent Trends Stricter Regulation and the Need for Stronger Compliance Awareness

In recent years, as China’s outbound investment oversight framework continues to improve, regulators have become increasingly stringent in reviewing ODI compliance. Since the second half of 2025, the Ministry of Commerce has repeatedly emphasized the need to manage irrational investments more effectively and encourage genuine, compliant overseas investment activities.

According to reports from Yicai, in early 2025, the National Development and Reform Commission issued a notice further standardizing corporate overseas investment behavior, explicitly requiring local governments to strengthen verification of the authenticity of filing materials to prevent risks such as fake investments and money laundering.

This means that in the future, when applying for filing, companies will not only need to submit comprehensive business plans and funding source explanations but may also face more rigorous background checks. At the same time, some regions are enhancing midand post-event supervision while streamlining service procedures. For example, in late 2025, the Shenzhen Municipal Bureau of Commerce launched a one-stop ODI filing service platform, offering end-to-end guidance from consultation to submission. While this improves efficiency, it also reflects the regulator’s growing emphasis on compliance in the filing process.

4. How to Navigate the Complexity of Filing

To handle the complexities of the filing process, companies should focus on the following strategies

1. Plan Ahead and Allow Sufficient Time

The filing process typically takes three to six months, and sometimes even longer. When developing overseas investment plans, companies should incorporate the filing stage into their overall timelines to avoid project delays.

2. Engage Professional Support

Filing involves multiple disciplines, including law, finance, and taxation. It is advisable to engage professional law firms, accounting firms, or compliance consultants to assist in preparing accurate and logically sound documentation that meets regulatory expectations.

3. Strategically Design the Investment Structure

The structure of the investment path directly affects the difficulty of filing and the efficiency of future operations. Factors such as whether to adopt a VIE structure, involve multi-tiered holdings, or use offshore entities can significantly influence the outcome of the filing review.

4. Monitor Policy Changes and Adjust Strategies Flexibly

Outbound investment policies are highly time-sensitive and region-specific. Companies should stay updated on the latest regulatory developments and be ready to adjust their investment direction and filing plans accordingly.

5. Conclusion

Investing in a Hong Kong company is a vital step for many enterprises seeking international growth. However, the filing process-a critical component-must never be taken lightly. In an evolving regulatory landscape, only by thoroughly understanding the filing system, strategically planning investment routes, and proactively seeking professional support can companies ensure steady and compliant progress toward achieving their going global strategy.
