Cross-Border Tax Issues in Settlement Agreements: Tax Reporting for International Settlement Sums

A single settlement payment can trigger tax liabilities in two or more jurisdictions. A Hong Kong employer paying a termination settlement to a former employee who has relocated to Singapore may face withholding obligations under Singapore’s tax code, while the employee might still be assessable to Hong Kong salaries tax on the same sum. The Inland Revenue Department (IRD) has sharpened its focus on cross-border settlement payments since 2023, following the introduction of enhanced transfer pricing documentation rules under Cap. 112 Inland Revenue Ordinance. The 2025-26 Hong Kong Budget announced an expanded network of Comprehensive Double Taxation Agreements (CDTAs), bringing the total to 50 jurisdictions. These agreements change the default tax treatment of settlement sums. A party who structures a settlement without considering the tax reporting obligations in both the paying and receiving jurisdictions risks double taxation, late-filing penalties, and delayed enforcement of the settlement agreement itself. This article sets out the procedural rules under Hong Kong law for tax reporting of international settlement sums, the applicable deadlines, and the forum in which disputes over tax treatment must be resolved.

The Legal Framework for Taxing Settlement Sums in Hong Kong

The IRD taxes settlement payments under two broad categories: compensation for loss of employment and compensation for breach of contract or tort. The distinction determines whether the payment falls under salaries tax (Part III of Cap. 112) or profits tax (Part IV of Cap. 112).

Step 1: Classify the settlement payment. Section 8(1) of Cap. 112 charges salaries tax on “income arising in or derived from Hong Kong from any office or employment.” The Court of Final Appeal in Commissioner of Inland Revenue v. Humphrey (2001) 3 HKCFAR 478 established that a termination payment is taxable as employment income if it represents compensation for loss of future earnings, but not if it compensates for loss of a capital asset or personal injury. The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 24 (revised 2018) confirms that the IRD applies a “source principle”: a settlement sum is chargeable to Hong Kong salaries tax only if the services giving rise to the payment were rendered in Hong Kong.

Step 2: Determine whether the settlement sum is “income” or “capital.” A payment for breach of a commercial contract, such as a settlement of a supply-chain dispute, is generally treated as a revenue receipt and chargeable to profits tax under Section 14 of Cap. 112. A payment for the cancellation of a capital asset, such as a settlement terminating a long-term distributorship agreement, may be capital in nature and not taxable. The IRD provides no statutory definition of “capital” versus “income.” The test remains the “badges of trade” principles from Commissioner of Inland Revenue v. The Hong Kong and Whampoa Dock Co. Ltd. (1960) HKLR 175.

Step 3: Apply the relevant CDTAs. Hong Kong’s CDTAs follow the OECD Model Tax Convention. Article 15 (Income from Employment) of most CDTAs provides that employment income is taxable only in the jurisdiction where the employment is exercised. If a settlement payment relates to employment exercised partly in Hong Kong and partly overseas, the IRD will apportion the sum. The 2025-26 Budget confirmed that Hong Kong’s CDTA with Saudi Arabia entered into force on 1 April 2025, and the CDTA with Bangladesh was signed in March 2025. These agreements override domestic law where the domestic law is less favourable to the taxpayer.

Tax Reporting Obligations for the Paying Party

A Hong Kong entity making a cross-border settlement payment must comply with reporting obligations under both Hong Kong law and the law of the payee’s jurisdiction.

Hong Kong reporting obligations. The paying party must file an IR56F form (Employer’s Return of Remuneration and Pensions) with the IRD within one month of making a termination payment to an employee, regardless of whether the employee has left Hong Kong. Section 52(4) of Cap. 112 requires the employer to notify the IRD of the employee’s cessation of employment and the amount of any severance or termination payment. Failure to file carries a maximum penalty of HK$10,000 under Section 80(1) of Cap. 112.

Withholding obligations in the payee’s jurisdiction. Hong Kong does not impose a general withholding tax on outbound payments. However, the paying party must check whether the payee’s jurisdiction imposes a withholding obligation on the payer. For example, Singapore’s Section 45 of the Income Tax Act 1947 requires a payer to withhold tax at 22% on certain payments to non-residents, including termination payments if the services were performed in Singapore. The People’s Republic of China’s Individual Income Tax Law (2018 amendment) imposes withholding on employment income paid to a non-resident individual who has worked in China for 183 days or more in a tax year. The Hong Kong payer must register with the foreign tax authority, file a withholding return, and remit the withheld tax within the prescribed period — typically 15 days under Chinese law.

Step 4: Obtain a tax clearance certificate. If the settlement sum exceeds HK$500,000 and the payee is a non-Hong Kong resident employee, the IRD may require the employer to obtain a tax clearance certificate under Section 77 of Cap. 112 before releasing the payment. The certificate confirms that the employee has no outstanding tax liabilities. The processing time is 4-6 weeks. The employer should not release the settlement sum until the certificate is issued.

Tax Reporting Obligations for the Receiving Party

The receiving party — whether an individual or a corporate entity — must report the settlement sum in the correct tax return and within the correct deadline.

Individual recipients. An individual who receives a settlement payment that is chargeable to Hong Kong salaries tax must include the amount in the annual Tax Return – Individuals (BIR60). The return is due within one month of issuance, typically in May of the following year of assessment. The IRD may issue an estimated assessment under Section 59(3) of Cap. 112 if the individual fails to file. The individual may apply for a provisional tax holdover under Section 63J if the settlement sum is not yet received or is disputed.

Corporate recipients. A corporate entity receiving a settlement payment that is chargeable to profits tax must include the amount in the Profits Tax Return (BIR51 or BIR54). The due date is generally one month from the date of issuance, with extensions available for cases with accounts made up to a date other than 31 December. The IRD’s practice, as stated in DIPN No. 21 (revised 2023), is to treat a settlement payment as taxable in the year of assessment in which the payment is received, not the year in which the cause of action arose.

Step 5: Claim foreign tax credit. If the settlement sum has been taxed in another jurisdiction, the recipient may claim a foreign tax credit under Section 49 of Cap. 112. The credit is limited to the lower of the foreign tax paid and the Hong Kong tax attributable to that income. The recipient must provide documentary evidence of the foreign tax paid, including the foreign tax assessment and proof of payment. The IRD will not allow a credit for foreign tax that could have been avoided by proper planning.

Dispute Resolution and Forum Selection

Disputes over the tax treatment of a cross-border settlement sum must be resolved through the statutory objection and appeal process under Cap. 112. The settlement agreement itself cannot override the IRD’s assessment.

Step 6: Object to an assessment. A taxpayer who disagrees with an IRD assessment must lodge a written notice of objection under Section 64 of Cap. 112 within one month of the date of the assessment notice. The notice must state the grounds of objection in sufficient detail. The IRD will issue a determination within a reasonable period. The taxpayer may appeal the determination to the Board of Review (Inland Revenue) within one month.

Step 7: Appeal to the Court of First Instance. A further appeal lies to the Court of First Instance on a question of law only, under Section 69 of Cap. 112. The Court of First Instance has no jurisdiction to review findings of fact. The Court of Appeal and the Court of Final Appeal hear subsequent appeals.

Step 8: Use the Mutual Agreement Procedure (MAP). If the dispute involves a double taxation issue under a CDTA, the taxpayer may request the IRD to initiate the MAP under the relevant CDTA. The MAP is an administrative procedure between the competent authorities of the two jurisdictions. The taxpayer must submit the request within three years of the first notification of the action resulting in taxation not in accordance with the CDTA. The IRD’s practice, as stated in DIPN No. 44 (revised 2022), is to process MAP requests within 24 months on average.

Illustrative case. Consider a hypothetical scenario: Company A, a Hong Kong trading firm, settles a dispute with an independent contractor resident in Japan. The settlement sum is HK$2 million for early termination of a service contract. The contractor performed services in Japan for 120 days in the relevant year. Under the Hong Kong-Japan CDTA (Article 14), the termination payment is taxable only in Japan if the contractor did not have a permanent establishment in Hong Kong. Company A does not withhold Hong Kong tax. The contractor reports the sum in Japan and pays Japanese income tax at 20%. The contractor then receives a Hong Kong profits tax assessment on the same sum. The contractor objects, citing the CDTA. The IRD withdraws the assessment. No double taxation arises.

Actionable Takeaways

1. Classify the settlement payment before drafting the agreement — the tax treatment depends on whether the sum is employment income, revenue receipt, or capital receipt, and the classification must be supported by the factual recitals in the settlement deed.
2. Check the payee’s jurisdiction for withholding obligations — Hong Kong does not impose withholding, but the payee’s jurisdiction may require the Hong Kong payer to register, withhold, and remit tax within a short deadline.
3. Obtain a tax clearance certificate before releasing a settlement sum exceeding HK$500,000 to a non-resident employee — the IRD will not issue the certificate retroactively, and releasing the payment without it may expose the employer to penalties.
4. File the objection within one month of the assessment — the statutory deadline under Section 64 of Cap. 112 is strict, and the Board of Review has no power to extend it.
5. Consider the MAP if double taxation arises under a CDTA — the three-year filing deadline runs from the first notification of the adverse tax action, not from the final assessment.
