Hong Kong Offshore Profits Claim: How the Source Test Actually Works
Hong Kong taxes profits by source, not by residence, so a Hong Kong company can pay nothing on genuinely offshore profits. But the exemption is a claim you have to prove, not a status you receive on incorporation – and the burden of proof sits entirely with you.
Three conditions, in order
Hong Kong charges profits tax only when all three of the following hold. The first two are rarely disputed. The third is where every offshore claim is won or lost.
- The person carries on a trade, profession or business in Hong Kong.
- That trade, profession or business derives profits.
- Those profits arise in or are derived from Hong Kong.
The order matters. A company claiming offshore treatment is not saying it does no business in Hong Kong. It concedes the first two conditions and disputes the third. You are not arguing that you are absent from Hong Kong; you are arguing that the operations which produced these particular profits happened elsewhere.
The exemption is also not a status. Nothing about incorporating in Hong Kong grants it. You claim it in your profits tax return, and the Inland Revenue Department decides whether the facts support it, sometimes years later.
What the IRD actually looks at
The governing idea is the operations test, and the IRD states it plainly: one looks to see what the taxpayer has done to earn the profits in question, and where he has done it. Four consequences follow, each of which catches somebody out.
Your operations, not your group’s. Source is attributed to the operations of the taxpayer that produced the profits, not to the operations of other members of the same group. A Hong Kong entity cannot borrow the activity of a foreign affiliate to make its own profits offshore.
Profit-producing work only. The relevant operations are the transactions that generated the profit, not everything the company did. Activities that merely precede or accompany them are set aside.
Where decisions get made is only one factor. The place of day-to-day business decisions counts, but the IRD says explicitly that it is not usually decisive. Founders often assume that directing the business from abroad settles the question. It does not.
Quality over quantity. The nature and quality of the activities matter more than how many of them there were. Cause and effect on the profit is what decides it.
The reverse holds a trap too. No overseas presence does not by itself make every profit Hong Kong-sourced, but the IRD is blunt about the odds: where the principal place of business is in Hong Kong and there is no presence abroad, profits are likely chargeable here.
Different businesses, different tests
There is no single formula. The test changes with how the company makes money, and applying the wrong one builds a claim that collapses under questioning.
Trading in goods
The locality of trading profits turns on where the contracts of purchase and sale are effected. Effected does not mean signed: it covers negotiation, conclusion and carrying out the terms. Following the Court of Appeal in Magna Industrial Co. Ltd v CIR, the IRD looks wider still, at how goods were procured and stored, how sales were solicited, how orders were processed and shipped, and how financing and payment were arranged.
The working rules are unforgiving. Both contracts effected outside Hong Kong and the profits are not taxable here. Either one effected in Hong Kong and the presumption flips against you. Sell to a Hong Kong customer and the sale contract is usually treated as effected here. And the rule that surprises people most: if concluding the contracts required no travel and was done from Hong Kong by telephone or over the internet, they were effected in Hong Kong.
Trading profits are also all-or-nothing. They are either wholly taxable or wholly exempt, and apportionment is not available.
Services and commissions
Service fee income is taxable if the services were performed in Hong Kong. Commission income follows where the agent’s own activities were performed, not where the principals sit. Unlike trading, service and manufacturing profits with substantial activity on both sides can be apportioned.
Manufacturing
Source is the place of manufacture, and where the finished goods are sold is irrelevant. For contract processing arrangements with a mainland Chinese enterprise, the IRD generally accepts a 50:50 apportionment.
FSIE is a second question
Since 2023 a great deal of anxious commentary has attached itself to Hong Kong’s foreign-sourced income exemption regime, much of it aimed at readers the regime does not touch. Two clarifications are worth more than any amount of substance-building.
FSIE applies only to members of multinational groups. The Inland Revenue Ordinance confines the regime to an MNE entity – a person that is, or acts for, a member of a group with at least one entity or permanent establishment outside the jurisdiction of the ultimate parent. An owner-managed Hong Kong company that is not part of such a group falls outside the regime.
FSIE does not replace the source test. The IRD is explicit that determining the source of profits is unaffected by the economic substance requirement, and that the two are considered in separate contexts. Source comes first. Only if income is genuinely foreign-sourced does FSIE ask its own question.
Where it does apply, the regime covers passive income: foreign-sourced interest, dividends, IP income and equity interest disposal gains from January 2023, extended to disposal gains on other property from January 2024. Such income is deemed Hong Kong-sourced and chargeable when received here, unless the entity meets the economic substance, nexus or participation requirement. Received is defined broadly, including income used to settle a debt of a Hong Kong business.
The substance requirement has no published minimum. The IRD sets no thresholds and decides each case on its own facts, weighing employee numbers and qualifications, the quality of management, and whether premises suit the activities. Outsourcing is permitted if the work is done in Hong Kong under the entity’s monitoring and control. For groups holding stakes, the participation route offers an alternative: at least 5% held continuously for 12 months, subject to a tax condition set at an applicable rate of 15% or more.
How the claim is actually made
Most guidance stops at the theory. The mechanics matter just as much, because a claim that is well founded but badly presented still invites an enquiry.
Split the income before you file
The starting point is separating income into what arose in Hong Kong and what did not. That split has to be defensible transaction by transaction, since for trading the test runs on the gross profit of each individual transaction rather than on the year as a whole. A company that lumps everything together and claims the total is offshore has made the weakest possible version of its own case.
Claim it in the return, and support it in the computation
The claim is made in the profits tax return for the year of assessment, with the amount treated as offshore stated separately, and it should be carried through clearly in the tax computation that accompanies the return. The return is the claim. There is no separate application form and no approval issued at incorporation.
Where the FSIE regime applies, the reporting is more prescriptive: an MNE entity reports specified foreign-sourced income in the profits tax return and the designated form for the year the income accrues, reports the chargeable amount for the year it is received in Hong Kong, and where no return has been issued must notify the Commissioner in writing within four months of the end of the basis period.
Expect the enquiry, and answer it from a file that already exists
The IRD tests claims after filing rather than before, and it may do so long after. What decides the outcome is whether contemporaneous evidence exists: contracts and their negotiation trail, correspondence showing where terms were agreed, travel records, shipping and payment documentation. Records assembled in response to a query are worth less than records kept as the transactions happened.
Buy certainty in advance if the structure justifies it
For a position you intend to rely on for years, an advance ruling converts an argument into a binding answer. A ruling is made under section 88A of the Inland Revenue Ordinance on the matters listed in Schedule 10, applied for on form IR1297, and it is subject to a fee. The IRD sets out the procedure in Departmental Interpretation and Practice Note No. 31. Rulings bind the Commissioner in the applicant’s own case; published rulings are for general reference only and give no protection to anyone else. MNE entities can also seek a ruling specifically on whether they meet the FSIE economic substance requirement.
Why offshore claims fail
Claims rarely fail because the law is unclear. They fail because the file does not support the story.
- Treating the exemption as a status. It is a claim, made in the return, that the IRD may test long after the fact. Companies that assumed offshore status at incorporation and never assembled evidence have nothing to produce when the enquiry lands.
- Confusing customer location with operations. Foreign customers, suppliers and bank accounts describe where your counterparties are. The test asks where your work happened.
- Building the wrong kind of substance. Renting premises, hiring general staff and setting up an office are named by the IRD as facts not directly related to trading activities, and therefore irrelevant to the source of trading profits. They may matter for FSIE. They will not rescue a source claim.
- Working from Hong Kong while claiming offshore. If the contracts were negotiated by a director sitting in Hong Kong, they were effected in Hong Kong, whatever the postal addresses on them say.
- Thin records. The burden of proof is on the taxpayer, and correspondence, travel records, contract drafts and shipping documents are what discharge it. Under the FSIE regime the IRD requires records for at least seven years after the transactions complete, or seven years after the income is received in Hong Kong, whichever is later – a sound benchmark for any claim file.
- Assuming apportionment will soften a bad claim. For trading profits it is not available at all.
If certainty matters more than optimism, the IRD offers advance rulings on the source of profits for a fee, and separately on compliance with the economic substance requirement. For a structure you intend to run for years, a ruling obtained early costs less than an assessment contested late. Our compliance and accounting service keeps that file current rather than reconstructing it under enquiry, and the same discipline applies when you open a bank account for an offshore company: the story you tell the bank must match the one in your tax file.
This is general information and not legal or tax advice. Hong Kong’s rates sit at 8.25% on the first HK$2 million of assessable profits and 16.5% above that for corporations, so the difference between a sustained claim and a failed one is substantial – and worth getting right before you file rather than after. If you are weighing Hong Kong against other bases, our comparison of Singapore, Hong Kong and Dubai sets out the trade-offs, and Hong Kong company formation covers the structures, requirements and process end to end.
Offshore claims, answered frankly
The questions founders ask most before making, or defending, an offshore claim.
Is a Hong Kong company automatically tax free on foreign income?
No. Hong Kong taxes only profits arising in or derived from Hong Kong, but the exemption for offshore profits is a claim you make in your profits tax return and must substantiate. Incorporation confers no offshore status, and the burden of proof sits with the taxpayer.
What test does the IRD use to decide the source of profits?
The operations test. The IRD looks at what the taxpayer did to earn the profits in question and where those operations took place. Source is attributed to the taxpayer’s own operations rather than those of other group members, and the nature and quality of the activities count for more than their number.
Do foreign customers and an overseas bank account make profits offshore?
No. Those facts describe where your counterparties and banking sit, not where you worked. For trading companies what matters is where the contracts of purchase and sale were effected, including their negotiation and conclusion. Contracts concluded from Hong Kong by telephone or over the internet are effected in Hong Kong.
Does renting an office abroad strengthen an offshore claim?
Not for the source test. The IRD names renting office premises, recruiting general staff and setting up an office as facts not directly related to trading activities, and therefore irrelevant to locality of profits. Such arrangements can matter under the FSIE regime, which is a separate question.
Does the FSIE regime apply to my company?
Only if it is a member of a multinational group. The regime applies to an MNE entity, meaning a person that is or acts for a group with at least one entity or permanent establishment outside the jurisdiction of its ultimate parent. Owner-managed Hong Kong companies outside such a group fall outside the regime.
Can profits be split between Hong Kong and offshore?
It depends on the business. Trading profits are treated as wholly taxable or wholly non-taxable and apportionment is not appropriate. For manufacturing and service income involving substantial activity both inside and outside Hong Kong, apportionment is available, and contract processing with a mainland enterprise is usually accepted on a 50:50 basis.
How do I actually make an offshore claim?
There is no separate application. The claim is made in the profits tax return for the year of assessment, with the amount treated as offshore stated separately and carried through in the accompanying tax computation. The IRD tests it afterwards, so the supporting evidence needs to exist before the enquiry arrives rather than be assembled in response to it.
Can I get certainty before I file?
Yes, within limits. The IRD provides advance rulings on the source of profits for profits tax purposes, subject to a fee, and separately allows MNE entities to seek a ruling on compliance with the economic substance requirement under the FSIE regime.
