Common Profits Tax Filing Risks for International Businesses in Hong Kong

For international businesses operating in Hong Kong, profits tax compliance is rarely straightforward. While Hong Kong’s territorial tax system is often viewed as simple, the practical application can be complex, particularly for cross border groups, regional headquarters and holding structures.

This article outlines the most common profits tax filing risks faced by international businesses, and what should be reviewed to reduce exposure in 2026.

Misunderstanding the territorial tax principle

Hong Kong taxes profits arising in or derived from Hong Kong. In practice, determining the source of profits requires a detailed analysis of where profit generating activities take place.

A frequent risk is assuming that income is offshore simply because customers, suppliers or manufacturing operations are located outside Hong Kong. The Inland Revenue Department focuses on where contracts are negotiated, concluded and managed, as well as where strategic decisions are made.

Where Hong Kong plays a substantive role, profits may be taxable even if transactions occur elsewhere.

Weakly supported offshore claims

Offshore claims remain one of the most scrutinised areas of profits tax filings. Common weaknesses include:

• Lack of contemporaneous documentation supporting offshore positions

• Inconsistent explanations across tax filings, audits and bank reviews

• Management activity taking place in Hong Kong despite offshore assertions

• Banking flows that contradict the stated operational model

Unsupported claims increase the likelihood of enquiries and prolonged correspondence with the tax authorities.

Inconsistencies between audited accounts and tax returns

Discrepancies between audited financial statements and profits tax returns are a common trigger for Inland Revenue Department questions.

This often arises where:

• Adjustments are made without clear explanations

• Intercompany transactions are treated differently for accounting and tax

• Management accounts do not align with statutory filings

Consistency across reporting is essential. Differences should be deliberate, documented and defensible.

Transfer pricing exposure

Transfer pricing continues to be an area of growing focus for international groups operating through Hong Kong.

Risks arise when:

• Intercompany service or trading arrangements lack formal agreements

• Pricing does not reflect arm’s length principles

• Documentation is prepared after the fact rather than contemporaneously

• Hong Kong profit levels do not align with the entity’s stated role

Transfer pricing weaknesses can lead not only to tax adjustments, but also penalties and reputational concerns.

Incorrect treatment of management and service income

Many Hong Kong entities charge management, technical or support fees to overseas group companies. Risks arise where:

• Services are not clearly defined or evidenced

• Fees are not supported by cost analysis

• Withholding tax implications in other jurisdictions are overlooked

• Income is incorrectly treated as offshore in Hong Kong

These issues are often identified during audits or cross border tax reviews.

Timing and late filing issues

Late filing of profits tax returns or delayed audited accounts increases scrutiny and reduces flexibility when addressing issues.

Recurring delays often indicate underlying problems with record keeping, governance or intercompany coordination. Once patterns are established, they are difficult to reverse.

Banking and tax reporting misalignment

Banks in Hong Kong increasingly compare tax filings with account activity. Where transaction flows do not align with declared business activities or tax positions, further reviews are triggered.

This can result in requests for additional documentation, restrictions on account activity or, in severe cases, account closures.

Taking a proactive approach

A proactive profits tax review allows international businesses to identify risks early, correct positions where necessary and strengthen documentation before enquiries arise.

For 2026, businesses should focus on aligning operational reality with tax reporting, improving documentation quality and ensuring consistency across audits, tax filings and banking disclosures.

Careful planning and early review reduce the likelihood of disruption and support more predictable tax outcomes in Hong Kong.
