How to claim offshore tax exemption in Hong Kong.

Hong Kong’s territorial tax system creates an opportunity for internationally active businesses. Unlike jurisdictions that tax global income, Hong Kong only imposes profits tax on income arising in or derived from Hong Kong, meaning companies with genuinely offshore operations may qualify for a full or partial exemption.

This guide explains what offshore tax exemption means, the conditions a company needs to meet and the documentation the Inland Revenue Department (IRD) expects when reviewing a claim.

What is the offshore tax exemption in Hong Kong?

An offshore company is a business that conducts its activities entirely outside its country of formation. Some offshore companies are regarded as residents of tax havens, where no corporate profits tax applies, for example, the British Virgin Islands and the Cayman Islands.

Although Hong Kong is not a tax haven, its territorial system produces a comparable outcome for businesses that operate internationally. Because Hong Kong only taxes profits derived from within its borders, a company registered there whose customers and suppliers are located entirely outside Hong Kong is likely to pay little or no profits tax.

A company qualifies for offshore tax exemption only if its business activities are carried on outside of Hong Kong and it receives non-Hong Kong sourced income. The location where profits originate, determined by where contracts are negotiated, where services are delivered and where key commercial decisions are made, is the central question in any exemption claim.

If your company receives passive income such as dividends, interest, intellectual property income or gains from the disposal of assets, separate rules apply under the Foreign-Sourced Income Exemption (FSIE) regime, which was updated in 2023. These rules operate alongside the general offshore exemption framework covered in this guide. See our guide to the FSIE regime for details.

Businesses that typically qualify include those that:

• Operate entirely outside of Hong Kong
• Do not offer services in Hong Kong
• Negotiate with suppliers and customers based outside of Hong Kong
• Execute business decisions and sign agreements outside of Hong Kong
• Effect purchase/sale contracts outside Hong Kong (for trading)
• Have no suppliers or customers in Hong Kong

Process and timing

The claim for tax exemption on offshore income is made in the company’s profits tax return submitted to the IRD. The first profits tax return is due 18 months after the incorporation date, with subsequent filings required every 12 months thereafter.

The IRD will consider the application carefully, and the review process can take several months. During this period, the IRD examines the structure of the company, how the offshore income is sourced, whether any Hong Kong entities are involved as suppliers or customers and the day-to-day activities of any company personnel based in Hong Kong.

Documents required for offshore tax exemption

The following documents should be submitted with the profits tax return to the IRD:

• Auditor’s report
• Completed profits tax return
• Tax computation claiming offshore tax exemption

Auditors preparing the audit report will require the following from the company:

• Bank statements
• Contracts
• Expense receipts
• Invoices
• Shipping documents

The IRD may request additional documents to support the exemption claim. It is important that the company maintains proper records to demonstrate that all transactions and activities were carried out outside of Hong Kong.

Additional documents that may be requested include:

• Communication records such as phone logs, emails and faxes with customers and suppliers
• Meeting memos with customers and suppliers
• Purchase orders and sales orders
• Shipping documents
• Travel documents and visa stamps confirming when and where visits to customers and suppliers took place

IRD evaluation

Offshore tax exemption claims in Hong Kong are not automatically accepted. The IRD applies a substantive review process, and understanding how that review works helps companies structure their operations and maintain appropriate records from the outset. The sections below cover the evidentiary standards the IRD applies, the risks created by a local presence in Hong Kong and the apportionment approach used when income is only partly offshore, and the options available if a claim is unsuccessful.

Evidentiary standards

The IRD evaluates each claim on its specific facts, placing significant weight on documentary evidence that demonstrates where the profit-generating activities actually occurred. A submission is generally stronger when it presents a consistent, corroborated account across multiple document types: contracts, correspondence, travel records and banking activity should collectively point to the same conclusion about where business was conducted.

The IRD tends to focus on the following evidentiary indicators:

• The location where contracts were negotiated and signed, supported by correspondence logs and meeting records
• The jurisdiction in which key commercial decisions were made, including pricing approvals and terms of trade
• The physical movement of directors and key personnel, evidenced by travel documents, visa stamps and accommodation records
• The flow of funds through bank accounts, and whether those accounts are held and operated offshore

Where records are incomplete or inconsistent, the IRD may draw adverse inferences or disallow the exemption in part or in full. Companies that rely on a single document type, invoices alone, for example, without supporting correspondence or travel evidence carry a greater risk of an unsuccessful outcome.

Local presence risk

A common area of scrutiny is the role of personnel or management based in Hong Kong. Even where a company’s customers and suppliers are located entirely outside Hong Kong, the IRD will examine whether profit-generating activities are being directed or carried out from within the territory. This is sometimes referred to as local presence risk.

Activities that may indicate a Hong Kong source of profits include:

• Directors or senior management conducting substantive negotiations from Hong Kong, including via phone or email
• Business decisions being approved or ratified by individuals ordinarily resident in Hong Kong
• Back-office or support functions in Hong Kong that are integral to executing offshore contracts
• The use of a Hong Kong address for commercial correspondence with overseas counterparties

The IRD may examine the nature of activities carried out during any days in Hong Kong, particularly where they involve substantive business functions rather than purely administrative or oversight matters.

Companies whose management teams are based in Hong Kong and conduct a meaningful volume of their work remotely with offshore counterparties may find it valuable to maintain detailed records that clearly distinguish between activities carried out inside and outside Hong Kong.

Apportionment

Where a company’s income derives from a combination of Hong Kong and offshore activities, the IRD applies an apportionment approach rather than treating the entire profit as either fully taxable or fully exempt. This reflects the principle that tax follows the source of profits, not simply the location of the customer or supplier.

Apportionment is most commonly relevant where:

• A company performs some services or fulfilment activities in Hong Kong in addition to its offshore operations
• A Hong Kong-based employee or director contributes to the generation of offshore contracts
• Procurement or logistics functions are partially managed from within Hong Kong
• Part of the contract negotiation process was performed in Hong Kong

The basis for apportionment is not fixed by statute and can vary depending on the nature of the business. The IRD may accept a turnover-based split, a cost-based allocation or another method that reasonably reflects the contribution of Hong Kong versus offshore activities to overall profits. Companies that expect their income to be partially sourced from Hong Kong activities benefit from documenting their chosen apportionment methodology clearly and applying it consistently across reporting periods.

Apportionment claims carry the same evidentiary requirements as full offshore exemption claims. The IRD will typically request supporting schedules showing how the offshore and Hong Kong portions of income have been calculated, and may cross-reference these against contracts, invoices and personnel activity records.

If a claim is unsuccessful

Where the IRD disallows an offshore exemption claim in whole or in part, the company has the right to lodge a formal objection within one month of the date of the assessment. The objection should set out the grounds of disagreement and, where possible, be accompanied by additional supporting documentation addressing the IRD’s specific concerns.

If the objection is not resolved to the company’s satisfaction, the matter can be appealed to the Board of Review, an independent tribunal that hears tax disputes in Hong Kong. In cases involving significant amounts or novel legal questions, further appeal to the Court of First Instance is possible.

Companies facing a disallowed claim should seek professional tax advice promptly. In some cases, it may also be appropriate to revisit the company’s operational structure or record-keeping practices to strengthen the position for future filings.

Double taxation agreements

Hong Kong has concluded comprehensive DTAs with over 50 jurisdictions, including mainland China, the United Kingdom, Japan and Singapore, among others. Where a DTA applies, it may affect the tax treatment of certain types of offshore income.

Companies that derive income from jurisdictions with which Hong Kong has a DTA should consider whether the relevant treaty affects their tax position, both in Hong Kong and in the counterpart jurisdiction. DTAs do not override the domestic rules on offshore exemption, but they can interact with them in ways that affect the overall tax outcome. Professional advice is recommended where treaty provisions may be relevant.

Conclusion

Hong Kong’s offshore tax exemption is a genuine and legitimate advantage for companies that structure and document their operations appropriately. Eligibility depends on where business activities actually take place, and the IRD’s review process is detailed and evidence-driven. In addition, under the tax laws in Hong Kong, the burden of proof lies with the taxpayers.

Companies that maintain thorough records of their offshore activities, correspondence and personnel movements are better placed to support a successful claim, whether for a full exemption or an apportioned one. Where a claim is challenged, formal objection and appeal mechanisms are available, and treaty protections under Hong Kong’s DTA network may also be relevant depending on the jurisdictions involved.
