Amazing
Our company does Audit in the first year, and we don't know the process ourselves. I saw someone recommending OneSec on the internet, so I tried to find it.They really knew the process well, everything went quickly and smoothly and the pricing was very affordable!

Starting a company and completing the registration process was troublesome and risky, so we look for OneSec's assistance. They prepared the documents incredibly quickly and handled the entire application process; I only needed to sign, and it was done in a few days. Their efficiency and attentive service saved us a lot of time and effort.
Blue Ocean Lab Limited
Amazing
We came across a LinkedIn post sharing a positive experience with OneSec’s EMF application support, so we decided to reach out. The OneSec team assisted us in organising the application materials, project proposal and supporting documents, while providing clear guidance throughout the process. This made the entire application much smoother. We were ultimately successful in securing funding, which has provided tangible benefits to our operations and cost management.

Because we were moving office, I needed to update the company address. Figuring out the process myself was stressful and I was worried about making mistakes. So I turned to OneSec for help.

Efficient, thoughtful service that saved me a lot of stress.

FAQs
How long does it take to open a Hong Kong company?
If using e-Registration, a Hong Kong company can be completed in as fast as 1–2 business days. Paper application takes about 5–7 business days.
Can Mainland resident and Foreign Nationals set up a company in Hong Kong?
Yes. As long as the conditions specified by government departments are met, both Mainland residents and foreign nationals can register a company in Hong Kong. The entire registration process can be completed remotely, with the company secretarial firm handling document processing and submission.
What is the minimum registered capital for registering a Mainland company?
Currently, most industries no longer have minimum capital requirements, and with the Mainland adopting a subscription system, enterprises do not need to inject capital immediately upon registration. However, some industries (e.g., education, finance, tourism) still have clear capital thresholds.
Is audit still required if the company has no actual operations?
Generally yes. Even if the company has no business income or transactions during the relevant financial year, a "dormant" audit report issued by a practicing accountant must be submitted to comply with tax filing requirements.
When should I start preparing for company audit?
It is generally recommended to start preparation as early as possible after the end of the financial year to match the tax filing deadline.
Can a newly established company apply for the BUD Fund?
Yes. The BUD Fund does not have a requirement for the company's establishment duration, but the enterprise must be able to prove substantive business operations and revenue sources (startups can provide business contracts or letters of intent as proof).
Can I apply for the BUD Fund even if I don't have a company in the Mainland?
You can still apply for the BUD Fund even without establishing a company in the Mainland. The applicability depends on the characteristics of the entire business model. For example, if the application involves cross-border e-commerce, it is not necessarily required to establish a company in the Mainland. However, if the proposed project involves providing services in the Mainland, then it is necessary to establish a company there.
