Quick Summary
- US founders can register in Hong Kong as a new standalone company, a subsidiary of their US entity, or a branch office
- Hong Kong's territorial tax system means offshore profits (including from US clients) are generally not taxed in HK
- US persons face additional obligations: CFC rules, GILTI, FBAR (FinCEN 114), and Form 5471 - these require a US international tax CPA
- No HK resident director required - you can be the sole director as a US citizen
- Air Corporate registers your HK company in 3–7 working days, fully remotely
Hong Kong has long attracted American founders and entrepreneurs for two specific reasons: its role as a gateway into mainland China via CEPA, and its territorial tax system that can deliver significant tax efficiency on profits generated outside Hong Kong.
But most guides are written for a generic "foreigner" audience. If you're a US founder - especially one with a Delaware C-Corp, an existing LLC, or ambitions to raise capital in Asia - the picture is more nuanced. There are US federal tax obligations that follow you wherever you incorporate, and the HK structure you choose affects how those rules apply.
This guide covers your three options for establishing a Hong Kong presence, walks you through the registration process step by step, and addresses the US-specific tax considerations that most articles completely ignore.
Your 3 Options for a Hong Kong Presence
Before you register, you need to decide which structure fits your situation. US founders typically have three options.
Option 1: New Standalone Hong Kong Company (Limited Company)
This is the most common path for US founders. You incorporate a brand-new Hong Kong private limited company (Ltd.) that is entirely separate from any existing US entity. The HK company has its own shareholders, directors, bank accounts, and tax filings.
Best for:
- Starting a new Asia-focused venture
- Keeping US and HK operations legally and financially separate
- Founders who want a clean slate in a new jurisdiction
- Companies targeting mainland China or Southeast Asian clients
The HK company is a full legal entity. Liability is limited to unpaid share capital. You can be the sole director and sole shareholder, even as a non-resident US citizen.
Option 2: Hong Kong Subsidiary of Your US Parent
Here, your existing US company (Delaware C-Corp, LLC, or other entity) becomes the registered shareholder of a new Hong Kong private limited company. The HK entity is legally a subsidiary - it has its own separate legal personality, but the US parent owns the shares.
Best for:
- US companies expanding an existing business into Asia
- Founders who want clear corporate ownership trail (common for VC-backed companies)
- Businesses where the HK entity will operate as a regional office or distribution hub
Key tax consideration: Because a US company (or US individual) controls the HK company, Controlled Foreign Corporation (CFC) rules may apply - more on this in the tax section below. Profits can be repatriated to the US parent, subject to US tax treatment.
Option 3: Branch Office of Your US Company
A branch is not a separate legal entity. It is simply a registered extension of your US company operating in Hong Kong. The US parent is directly liable for all branch obligations.
Best for: Very few SME scenarios. Branches are occasionally used by professional services firms or financial institutions.
Why most founders avoid it: The branch has no separate liability shield. US tax treatment is more complex. The Companies Registry requires filing the US company's constitutional documents. For most founders, either Option 1 or Option 2 is better.
Quick Comparison
| Option 1: Standalone | Option 2: Subsidiary | Option 3: Branch | |
|---|---|---|---|
| Legal separation from US | Full | Full | None |
| Liability shield | Yes | Yes | No |
| US CFC rules apply | Yes (if US person owns >50%) | Yes | N/A (treated as US entity) |
| Best for | New Asia venture | Extending US business | Professional services only |
| Complexity | Low | Medium | High |
Why US Founders Choose Hong Kong Specifically
Territorial Taxation
Hong Kong operates a territorial tax system: only profits sourced in Hong Kong are subject to profits tax. Profits generated from business activities conducted entirely outside Hong Kong - including serving US clients, providing services to European companies, or licensing IP used abroad - are generally offshore and tax-exempt in Hong Kong.
This is a meaningful structural advantage. A HK company with primarily offshore income can legitimately pay very little (or zero) HK profits tax on that income, provided the offshore claim is properly documented.
Low Corporate Tax Rate
For profits that are Hong Kong-sourced, the rate is competitive:
- 8.25% on the first HKD 2 million of assessable profits (~USD 258,000)
- 16.5% on profits above HKD 2 million
There is no capital gains tax, no withholding tax on dividends paid to foreign shareholders, and no restrictions on repatriating profits out of Hong Kong.
Gateway to Mainland China via CEPA
The Closer Economic Partnership Arrangement (CEPA) gives Hong Kong companies preferential access to the mainland Chinese market - including reduced tariffs, easier market entry for services sectors, and professional recognition. For US founders targeting the world's largest consumer market, a HK company is often more useful than a US entity or a Singapore entity.
Common Law Legal System
Hong Kong uses English common law, which US founders find familiar. Contracts are enforceable in a transparent legal system. IP protections are robust and internationally recognised.
No FX Controls, USD-Friendly Banking
Hong Kong has no foreign exchange controls. The HKD is pegged to the USD (7.75–7.85 range). Multi-currency accounts in USD, HKD, EUR, and CNY are widely available. This makes treasury management straightforward for a US-headquartered operation.
Simple Incorporation, No Residency Requirement
Unlike Singapore, Hong Kong does not require a resident director. You can incorporate, own, and operate a Hong Kong company entirely as a non-resident US citizen. Air Corporate handles the company registration for foreigners end to end.
US-Specific Tax Considerations
This section is the most important one in this guide - and the one most other articles skip entirely.
Registering in Hong Kong does not eliminate your US tax obligations. The US taxes its citizens and residents on worldwide income. When you own a foreign corporation, additional reporting and potentially additional tax obligations arise under US federal law.
Disclaimer: Air Corporate handles Hong Kong company formation and HK compliance. US federal tax matters require a qualified US international tax CPA or attorney. The following is informational only.
Controlled Foreign Corporation (CFC) Rules
If US persons collectively own more than 50% of a foreign corporation, that corporation is classified as a Controlled Foreign Corporation under US tax law. For most US founders owning their HK company, this threshold is easily met.
CFC status triggers Subpart F rules: certain categories of income - particularly passive income such as dividends, interest, and rents - are taxed to the US shareholder even if not distributed. However, active business income (genuine operating income from running a business) is generally not Subpart F income and is not taxed until distributed.
Practical implication: If your HK company earns active operating income (consulting, services, sales), CFC status alone does not create immediate US tax. But if the HK company earns passive income (e.g., interest on cash holdings), that may be taxed to you as a US shareholder in the year earned.
GILTI - Global Intangible Low-Taxed Income
The Tax Cuts and Jobs Act of 2017 introduced GILTI, which applies to US shareholders of CFCs. GILTI is broadly defined as foreign income above a 10% return on tangible assets. The effective tax rate on GILTI ranges from 10.5% to 21% depending on your situation and available credits.
GILTI affects corporations more predictably than individuals. US individuals owning HK companies may face full GILTI inclusion without the benefit of the foreign tax credit deductions available to C-Corps. This is an area where US tax advice is essential before you structure.
FBAR - Foreign Bank Account Reporting
If you have a financial interest in, or signature authority over, a Hong Kong bank account that exceeds USD 10,000 at any point during the calendar year, you must file FinCEN Form 114 (the FBAR) with the Financial Crimes Enforcement Network by April 15 each year (with automatic extension to October 15).
This is a reporting requirement, not a tax. But the penalties for non-compliance are severe - up to USD 10,000 per violation for non-willful failure, and higher for willful failure. For US founders with HK business accounts, FBAR filing is essentially mandatory.
Form 5471 - Information Return for Foreign Corporations
US persons who own 10% or more of a foreign corporation must file IRS Form 5471 with their annual tax return. This is an information return that reports the foreign corporation's income, balance sheet, and transactions with US persons. Failure to file carries a USD 10,000 penalty per year.
For US founders owning their HK company, Form 5471 is a standard annual filing requirement.
The Takeaway for US Founders
Hong Kong remains one of the most tax-efficient jurisdictions in the world, even for US persons. The territorial tax system means your HK company can genuinely reduce its Hong Kong tax bill on offshore profits. But the US tax layer - CFC, GILTI, FBAR, Form 5471 - requires proper structuring and compliance.

Step-by-Step: How to Register Your Hong Kong Company
Once you've chosen your structure, the registration process is straightforward. Air Corporate can complete this for you in 3–7 working days. Here's what happens:
Step 1 - Choose your company name Your company name must end in "Limited" and cannot be identical or misleadingly similar to an existing registered name. You can choose an English name, a Chinese name, or both. Air Corporate checks availability before submission.
Step 2 - Appoint at least one director Directors can be of any nationality and do not need to be Hong Kong residents. A US founder can serve as the sole director. Directors must be natural persons (not corporate entities) under most standard structures.
Step 3 - Appoint a company secretary A company secretary is a statutory requirement for all Hong Kong companies. The secretary must be a Hong Kong resident individual or a licensed Trust and Corporate Service Provider (TCSP). Air Corporate provides this service.
Step 4 - Provide a registered address Your HK company must have a registered address in Hong Kong. This does not need to be your actual office - a registered address service suffices. Air Corporate provides a registered address as part of the incorporation package.
Step 5 - Submit incorporation documents The key documents are:
- Incorporation Form (NNC1 for companies limited by shares)
- Articles of Association
- Notice to the Business Registration Office (IRBR1)
These are submitted electronically via the Hong Kong Companies Registry e-Registry. Air Corporate prepares and submits all documents on your behalf.
Step 6 - Receive Certificate of Incorporation The Companies Registry typically issues the Certificate of Incorporation within 1–3 working days of a complete application. You'll receive a digital copy immediately; a physical certificate can be ordered separately.
Step 7 - Obtain Business Registration Certificate Simultaneously with incorporation, a Business Registration Certificate (BRC) is issued by the Inland Revenue Department. This is your licence to operate. It must be renewed annually.
Step 8 - Open a bank account See the banking section below.
Total timeline with Air Corporate: 3–7 working days from document submission. Register a company in Hong Kong without visiting in person.
Documents You'll Need (as a US Founder)
Prepare the following before you start:
- Passport - certified copy of your US passport (all directors and significant shareholders)
- Proof of residential address - US utility bill or bank statement dated within 3 months
- Proposed company name - have one or two options ready
- Share structure - number of shares, par value (HKD 1 per share is standard), and allocation among shareholders
- Business description - a plain-language description of what the company will do
- If forming a subsidiary: your US company's Certificate of Incorporation and Articles of Association (or LLC Operating Agreement), plus proof of the US company's registered address
Air Corporate will guide you through document certification requirements. In most cases, no notarisation or apostille is required for straightforward incorporations.
Opening a Bank Account as a US Founder
Banking is where many US founders hit friction. Because you are a non-resident and a US person (which triggers FATCA reporting obligations for HK banks), traditional banks apply stricter due diligence.
FATCA and HK Banks
Under FATCA (Foreign Account Tax Compliance Act), Hong Kong banks are required to identify US account holders and report their account information to the IRS via Hong Kong's tax authority. This is standard compliance - it is not a barrier to opening an account, but banks will ask for your US Tax Identification Number (TIN or SSN) and may ask you to complete a W-9 form.
Recommended Options for US Founders
Traditional banks (HSBC, Hang Seng, Standard Chartered): Possible but slow. HSBC in particular has improved its remote account opening in recent years, but approval timelines are 4–8 weeks and the due diligence is thorough. Recommended once your company has some operating history.
Digital and fintech options (recommended for initial setup):
- Statrys - HK-based, non-resident-friendly, fully remote onboarding, multi-currency accounts (USD, HKD, EUR, CNY). Popular with HK companies run by non-residents.
- Airwallex - HK-headquartered global fintech. Excellent for USD transactions and international transfers. Remote onboarding available.
- Aspire - Southeast Asia-based but widely used for HK companies. Multi-currency, remote-friendly.
For most US founders, starting with Statrys or Airwallex while applying in parallel for a traditional bank account is the pragmatic approach. See our full guide on opening a non-resident bank account in Hong Kong.
Ongoing Compliance Requirements
Registering is the easy part. Maintaining your company in good standing requires annual filings:
Annual Return (NAR1) Due within 42 days of your incorporation anniversary each year. Reports current directors, shareholders, and company secretary. Filed with the Companies Registry.
Profits Tax Return The Inland Revenue Department issues your first Profits Tax Return approximately 18 months after incorporation. Subsequent returns are issued annually. You must file even if you are claiming offshore tax exemption - the exemption must be applied for and supported with documentation.
Business Registration Certificate Renewal Your BRC must be renewed annually. Air Corporate handles this as part of ongoing company secretary services.
Statutory Records Your company secretary must maintain statutory registers (register of members, register of directors, register of charges) at your registered address.
Estimated Annual Compliance Cost HKD 5,000–15,000 per year, covering company secretary services, registered address, annual return filing, and BRC renewal. Profits tax filing is separate and depends on the complexity of your accounts.

US Founders and HK Companies: Common Questions
Can I be the sole director of a HK company as a US citizen? Yes. There is no nationality or residency requirement for directors of Hong Kong companies. A single US-resident director is perfectly valid.
Do I need a Hong Kong resident director? No. This is a common misconception - Singapore requires at least one resident director, but Hong Kong does not.
Can my Delaware C-Corp own the HK company? Yes. Your Delaware C-Corp becomes the sole shareholder of the HK private limited company. The HK entity is a wholly-owned subsidiary of the C-Corp. This is a common structure for US startups expanding into Asia.
Can my LLC own the HK company? Yes, with some nuance. From a HK perspective, a US LLC is a valid shareholder. However, the US tax treatment of a LLC-owned CFC can be complex depending on how the LLC is taxed (disregarded entity vs. partnership). Get US tax advice before structuring this way.
Can I raise VC funding through the HK company? Yes. Hong Kong is an established venture capital hub, particularly for Asia-focused rounds and Greater China investors. Many US founders establish a HK holding company specifically to access HK- and China-based VC funds. A HK private limited company can issue shares, preference shares, and convertible instruments in ways familiar to institutional investors.
Is there a minimum share capital? No statutory minimum. Most HK companies are incorporated with HKD 1–10,000 in authorised share capital, with HKD 1 per share as the standard par value.
Can I operate entirely remotely? Yes. You never need to visit Hong Kong to incorporate, run, or manage your company. Banking can be opened remotely via fintech providers. Annual filings are handled by your company secretary.
FAQ
How long does it take to register a Hong Kong company? With Air Corporate, the Certificate of Incorporation is typically issued within 1–3 working days of submitting complete documents. The full process from enquiry to registered company is 3–7 working days.
Do I need to visit Hong Kong? No. The entire incorporation process - document submission, company secretary appointment, and registered address - can be completed remotely. Banking via Statrys or Airwallex is also fully remote.
What is the minimum share capital for a HK company? There is no minimum share capital requirement. Most companies are incorporated with HKD 1 in issued share capital, though HKD 1,000–10,000 is more common in practice.
Do I pay US taxes on profits my HK company earns? It depends on the nature of the income and your ownership structure. Active business income in a CFC is generally not taxed in the US until distributed. Passive income may be taxable under Subpart F. GILTI rules may apply to certain income regardless. You should work with a US international tax CPA to model your specific situation before incorporating.
Can my HK company invoice US clients? Yes. A HK company can contract with and invoice clients anywhere in the world. The key question - which affects HK tax, not US tax - is whether the services were performed in Hong Kong or offshore. If the work is done outside Hong Kong, the income is generally offshore and may qualify for tax exemption.
