Reviewed by Captime's licensed team (TCSP Licence TC010212) · Updated · Editorial policy
Discover 5 steps to claim Hong Kong offshore tax exemption, from testing profit source and gathering evidence to filing with the IRD and handling enquiries.
Key Takeaways
- The source test identifies the taxpayer’s profit-producing operations and where they occurred.
- Different income streams may require different source tests.
- The nature and effect of activities matter more than their quantity.
- Evidence should connect contracts, communications, delivery and payment to the audited accounts.
- Business records generally must be retained for at least seven years, and the source position should be reassessed whenever operations change.
Quick Answer
Claim offshore profits in the annual Profits Tax Return with a reasoned statement and evidence.
Eligibility depends on where profit-producing operations occurred—not customer or bank location.
What Is Hong Kong Offshore Tax Exemption?
“Offshore tax exemption” is a commonly used business term for claiming that particular profits are not chargeable to Hong Kong Profits Tax because they do not arise in or derive from Hong Kong. It is not a blanket exemption attached permanently to the company.
Subject to other provisions of the Inland Revenue Ordinance, section 14 charges relevant profits arising in or derived from Hong Kong. The IRD’s territorial source guidance therefore examines the operations that produced the profits and where they took place.
Important: A Hong Kong bank account, registered office, company secretary or certificate of incorporation does not decide the source of profits by itself. The IRD considers the totality of the company’s income-producing activities.
Five Steps to Build a Defensible Offshore Claim
A defensible offshore claim requires five connected actions: test the source of each profit stream, collect evidence, disclose the position clearly, answer IRD enquiries and reassess the facts every year.
1 Check Whether the Profits Are Genuinely Offshore
Start with the commercial facts. Identify the taxpayer’s own operations that produced each category of gross profit and where they occurred.
For trading profits, examine procurement, purchase and sale negotiations, contract conclusion, order processing, shipping, financing and payment. A signature location alone is not decisive.
For a service business, focus on where the substantive services were performed. Overseas customers do not make profits offshore when the actual work is carried out in Hong Kong.
A group company’s or contractor’s work is not automatically the taxpayer’s operation. It may be relevant when performed on the taxpayer’s behalf.
2 Build the Evidence File From Day One
A successful claim depends on documents that match the company’s explanation. Reconstructing records only after an IRD enquiry is difficult and may expose inconsistencies.
Offshore Evidence Checklist
- Customer and supplier contracts showing how and where terms were negotiated and accepted
- Purchase orders, sales orders, invoices and delivery records
- Email, meeting and call records identifying the people and locations involved
- Travel records, calendars and supporting expense documents
- Bills of lading, courier records and other evidence of the movement of goods
- Bank statements and payment records showing the transaction trail
- Bookkeeping records and source documents that reconcile with the audited financial statements
Under section 51C, sufficient business records generally must be kept for at least seven years. Electronic records should remain complete, readable and capable of being retrieved if the IRD asks for them.
3 Make the Claim in the Profits Tax Return
There is no standalone offshore exemption application form. Report the net offshore profits excluded from assessable profits at BIR51 Item 10.1. If the amount includes offshore profits attributable to using the Internet to accept orders, sell goods, provide services or accept payment, also complete Item 10.2.1.
The BIR51 Notes and Instructions require a reasoned statement capable of being supported by evidence. Audited accounts support the reported figures but do not, by themselves, establish the source of profits or amount to IRD acceptance of the claim.
4 Prepare for IRD Enquiries
The IRD may ask who negotiated contracts, where orders were accepted, who performed services, where goods moved and whether Hong Kong-based people performed profit-producing work.
Answer specifically and attach supporting documents. The response should remain consistent with the company’s website, contracts, invoices, accounts, staffing and travel history.
IRD review time varies according to the transaction structure, available evidence and number of follow-up enquiries. Founders should not treat general market estimates as an official IRD processing standard.
5 Reassess the Claim Every Year
An accepted offshore position is not permanent. The company must reconsider the source of profits for every year and preserve evidence as the business evolves.
A claim may weaken if the company hires Hong Kong sales staff, moves negotiations into Hong Kong, or performs core services there. The complete operational facts remain important.
- Hong Kong staff negotiate or close sales: Core sales activity may become Hong Kong-based. Recommended action: Review the source position before filing.
- Services move to Hong Kong: Service location is a major source factor. Recommended action: Separate the relevant income and retain project records.
- Public statements conflict with evidence: Contradictions can weaken credibility. Recommended action: Preserve dated records and reconcile genuine differences.
- The company joins an MNE group: The FSIE regime may become relevant. Recommended action: Review the rules before receiving foreign income.
Offshore Profits Claim vs the FSIE Regime
The traditional source test and Hong Kong’s Foreign-sourced Income Exemption regime are separate. The source test continues to determine the locality of active trading and service profits.
The FSIE regime may deem specified foreign-sourced interest, dividends, intellectual property income and disposal gains received in Hong Kong by an MNE entity taxable unless the relevant economic-substance, participation, nexus or intra-group relief conditions apply. It applies to MNE entities regardless of revenue or asset size; a standalone Hong Kong company outside an MNE group is not within the regime.
Risks Founders Should Understand
Do not claim offshore treatment when the facts do not support it. Rejection may lead to an assessment of additional tax, but rejection alone does not automatically create a penalty.
Under the IRD Penalty Policy, consequences depend on matters such as an incorrect return or information, the amount of tax undercharged, and the degree of culpability. Accurate disclosure and contemporaneous records are therefore essential.
Hong Kong offshore treatment does not guarantee tax-free profits worldwide. Jurisdictions where directors, employees or owners are located may apply their own tax rules.

Frequently Asked Questions
Possibly, but the IRD says profits are likely to be chargeable in the vast majority of cases where the principal place of business is in Hong Kong and there is no overseas business presence. For e-commerce, an overseas server or website host is not decisive; the company must prove where its core profit-producing operations occurred.
Usually not. The IRD generally treats trading profits as wholly taxable or wholly non-taxable after examining all relevant operations.
Yes, where substantial income-producing services occur both in and outside Hong Kong. The apportionment basis must reflect the work and supporting evidence.
Not automatically. Their activities may be relevant when performed on the taxpayer’s behalf, and the facts support attribution.
Hong Kong business records generally must be retained for at least seven years and remain retrievable and reconcilable with the accounts.
Yes, subject to a fee, the applicable rules and full particulars of the proposed arrangement. This is separate from an annual offshore profits claim.

Here's something that surprises almost everyone. There is no application form for Hong Kong offshore tax exemption. No form, no government fee, no certificate on the wall. And yet, done properly, a Hong Kong company can legally pay 0% profits tax on income earned entirely outside the city. So, how do you actually claim offshore tax exemption for your Hong Kong company? You claim it inside your annual profits tax return. There is no separate application. And you win it with evidence. Proof that the activities producing your profits happened entirely outside Hong Kong. The burden of proof sits with you, not the taxman. In this video, the five steps of a successful claim.
And step five is where most claims eventually go to die. So stay for that. Step one. Check whether your profits are genuinely offshore before you claim anything. Hong Kong Taxes on the Territorial Source Principle. Section 14 of the Inland Revenue Ordinance. Chapter 112. Only profits arising in or derived from Hong Kong are taxed. The test the department applies, set out in its practice note on the locality of profits, DIPN 21, is beautifully simple to say and brutally factual to apply. What have you done to earn the profits and where did you do it? Remember that question. It comes back later. For traders, the key factor is where your purchase and sale contracts are affected.
And affected means negotiated, concluded, and executed, not just signed. Picture a founder in London running a Hong Kong company. Suppliers in Shenzhen, that's the manufacturing hub just across Hong Kong's northern border in mainland China. Customers in the United States. Goods shipped direct, never touching Hong Kong. That is the classic pattern. For service businesses, it's simpler. Where do you physically perform the work? And one hard rule. Trading profits are all or nothing. Either the whole profit is offshore or the whole profit is taxable. There is no splitting. Step 2. Build your evidence file from day one, not at filing time. The department does not take your word for anything.
A successful claim rests on documents. Contracts and purchase orders showing where terms were negotiated. Emails and call records showing where decisions were made. Travel records proving where you were when deals happened. Shipping documents proving goods never entered Hong Kong. And bank records showing the money trail. This sits on top of the bookkeeping every Hong Kong company must already do. The books of account, source documents, and daily money records we covered in our bookkeeping video. Think of the offshore file as a second layer. Same discipline pointed at one question. Where was the work done?
Reconstructing two years of evidence after the department asks is somewhere between painful and impossible. Collecting it as you go is almost free. Step 3. Make the claim in your profits tax return. Your first return typically arrives about 18 months after incorporation. And you have three months to file that first one. The claim itself is a disclosure inside the return with a supporting schedule. And this is important. Your financial statements still need to be audited. Every active Hong Kong company needs an audit. Offshore claim or not. We made a whole video on that. Your auditor reports on the numbers. The offshore claim is a tax position built on top of them.
The government charges nothing for making the claim. Your real costs are the audit and whatever professional help you use to present the claim properly. Present it well the first time. A clear, documented claim invites fewer questions than a bare one-liner hoping nobody asks. Step 4. Expect questions and answer them properly. The department reviews offshore claims rather than rubber stamping them. A straightforward, well-documented claim typically resolves in 3 to 6 months. A queried one can run 6 to 12. Enquiry letters usually give you one month to respond. And here's the pattern. Every enquiry letter is really that step one question in disguise.
What did you do to earn this profit and where? Who negotiated this contract? Where was this order solicited? Who arranged the financing? Answer specifically, consistently, and with documents attached. Inconsistency is the claim killer. If your answers drift between letters or contradict your website, your invoices, or your travel records, the review hardens. If you did the work outside Hong Kong and your file proves it, this stage is administrative, not adversarial. And Step 5. The one I warned you about. Offshore tax exemption is not a trophy. It's a position you re-earn every year. Each year's return repeats the claim. And the department revisits accepted claims from time to time.
So the evidence discipline never stops. Here is where claims die. The business quietly changes. You hire a Hong Kong salesperson. You start serving Hong Kong customers. You move negotiations to Hong Kong. Any of these can flip profits onshore, and the facts of each year decide that year. If you want certainty before committing to a structure, the department offers an advance ruling on the source of profits. The fee is HK$45,000, covering 23 hours of official time, with extra hours billed at roughly HK$1,730 to HK$2 ,650. Optional, most small companies simply file well-documented claims. But the option exists. Now the honest part. 5%.
If the department finds profits were understated, penalties can reach up to three times the tax undercharged. Never claim aggressively. Second, offshore in Hong Kong is not tax -free everywhere. If you run the company from London, your home country may have its own view of where that company is really taxed. Get advice on both ends. Third, a newer regime introduced in 2023, the Foreign Sourced Income Exemption regime, adds substance requirements for some foreign passive income, but it applies to members of multinational groups, not typical standalone companies. If you're part of a group, check before you file. And as we said in our 0% tax video, Hong Kong is low-tax, not low-standards.
The exemption is real, for companies whose facts are real. The facts in 30 seconds. Hong Kong offshore tax exemption is claimed inside your annual profits tax return. No separate application, no government fee. The test. What did you do to earn the profits and where? Trading profits are all or nothing. Evidence is everything, collected from day one. First return. About 18 months in, 3 months to file. Reviews run 3-6 months or 6-12 if queried. Inquiry letters give you 1 month each. The audit still happens. And the claim must be re-earned every year as your facts evolve. At CapTime Corporate Management Limited, we prepare offshore claims the way the department likes to see them.
