Hong Kong Offshore Profits Tax Claims and Tax Exemption

Hong Kong does not tax residents on worldwide income. It applies a territorial basis: only profits arising in or derived from Hong Kong are subject to profits tax. If your profit-generating activities happen outside Hong Kong (contracts negotiated overseas, services delivered abroad, manufacturing in other countries), those profits may fall entirely outside the charge.

Profits tax rates are already low at 8.25% on the first HK$2 million of assessable profits and 16.5% thereafter for corporations. For income that qualifies under a successful offshore claim, the effective rate can be 0%.

When a company files its annual profits tax return it can declare part or all of its income as offshore. If the Inland Revenue Department accepts the claim, that income is excluded from the assessment. Nothing happens automatically: the claim must be made each year, supported by documentation, and is subject to IRD review.

Any Hong Kong company filing a profits tax return can make a claim (there is no restriction by size, industry or shareholder nationality), but it has to be based on genuine facts.

The IRD applies a three-part test: the person must carry on a trade, profession or business in Hong Kong; the profits must arise from that business; and the profits must arise in or derive from Hong Kong. It is the third condition that separates onshore from offshore income. The official framework is set out in Departmental Interpretation and Practice Note No. 21 (DIPN 21).

There is no single universal rule. For trading businesses the IRD looks at where contracts are negotiated, concluded and executed, and where employees sit. For services, where the services are physically performed. For manufacturing, where the manufacturing takes place. For agency and commission income, where the agent's profit-generating activity occurs. In every case the IRD weighs the totality of facts, which is why organised documentation decides most claims.

Separate the income. Split profits into onshore (activities carried out in Hong Kong, taxable) and offshore (claimable as exempt), supported by contracts, invoices, correspondence, employee records and management records showing where the activity took place.

File the return. Declare offshore income in Part 10 of the profits tax return, and state in the tax computation the amount claimed and the rationale. Vague or unsupported claims invite deeper scrutiny.

Respond to the enquiry letter. Within roughly six to eight weeks the IRD usually issues an enquiry requesting supporting documents and a detailed explanation of operations, contracts and profit-generating activity. This is standard procedure, not a rejection, but the quality of the response matters, and follow-up enquiries are common.

Await the decision. If approved, the income is excluded from the assessment and the approval typically carries a three-year validity period, though a claim must still be made each year. If denied, the income is taxed at the standard rate and the company can object to the assessment.

Where certainty matters before filing (significant transactions or new structures), you can apply to the IRD for an advance ruling: a written statement of how a specific transaction will be treated. The application fee is HK$45,000, covering up to 23 hours of IRD staff time, with additional hours charged at HK$1,730 to HK$2,650.

The four failures we see most often: insufficient documentation of where activities actually occurred; mixing onshore and offshore activity without fair apportionment; filing without professional support in a process that turns on legal interpretation of facts under DIPN 21; and assuming a prior approval carries forward when the claim must be made afresh each year.

We run a viability review of the business model and advise honestly whether a claim is supportable, review documentation against the IRD's evidentiary requirements, prepare and file the claim as part of the annual profits tax return, manage IRD enquiry correspondence on your behalf, and prepare advance ruling applications where they are justified.

Every case is assessed on its own facts, including the cases where we advise that a claim would be difficult to sustain.

An offshore claim is one of several ways Hong Kong businesses can be exempt from profits tax on part of their income. Under the territorial source principle, profits arising outside Hong Kong are not taxable here. Separately, the foreign-sourced income exemption (FSIE) regime sets conditions, such as economic substance in Hong Kong, under which certain foreign-sourced dividends, interest, disposal gains and IP income received by members of multinational groups remain exempt.

We assess which route applies before a claim is prepared, so the position filed with your profits tax return is the one that will stand up.

For businesses relocating from the UAE to Hong Kong, or using Hong Kong as an international holding or trading hub, the offshore profits claim is often highly relevant.

Sells goods to customers in Asia, the Middle East, or Europe but negotiates and executes contracts outside Hong Kong

Provides services to overseas clients from offices outside Hong Kong

Operates manufacturing facilities in mainland China, Southeast Asia, or elsewhere

A significant portion, or all of your profits may qualify as offshore under Hong Kong tax law.

Many companies from the UAE establish Hong Kong entities precisely because of the combination of Hong Kong’s credibility as a financial centre and the potential for legitimate offshore tax treatment on non-HK-source profits.
