⚠️

⚠ BEPS Treaty-Shopping Compliance: The Principal Purpose Test Is Being Applied

Post-BEPS, Hong Kong's CDTAs now include the OECD MLI Principal Purpose Test. Structures designed primarily to access treaty benefits without genuine commercial substance in Hong Kong are being challenged globally. The PRC's SAT in particular has become significantly more aggressive in challenging HK holding company arrangements. Penalties and retrospective assessments follow when arrangements fail the PPT.

よくあるお悩み

以下の税務問題でお困りではありませんか？

Unexpected Permanent Establishment Risk

A single employee or dependent agent overseas can create a taxable PE, triggering full corporate tax liability in that jurisdiction. Post-BEPS Article 5 amendments have lowered the threshold significantly.

⚠ Risk: Full corporate tax exposure in overseas jurisdiction discovered only during audit

Withholding Tax Overpayment (10–25%)

Without a properly claimed DTA, WHT on dividends, interest, and royalties runs 10% to 25%. Hong Kong's treaty network can reduce this to 0–5% — but only with correct documentation and residence certificates.

⚠ Risk: Millions in excess WHT absorbed annually without refund applications

Double Taxation on the Same Income

When two jurisdictions both claim taxing rights over your income, the same profit is taxed twice with no relief. Genuine double taxation arises most frequently in cross-border employment, IP licensing, and differently-characterised payments.

⚠ Risk: Same income taxed twice with no automatic treaty relief mechanism

BEPS Treaty-Shopping Compliance Risk

Hong Kong's CDTAs now include the MLI Principal Purpose Test. Structures without genuine commercial substance are being challenged globally, with the PRC SAT particularly aggressive.

⚠ Risk: Retrospective denial of treaty benefits plus penalties and interest

ご質問への迅速な回答

Hong Kong has signed more than 45 CDTAs as at 2026, with new agreements being negotiated. The most commercially significant are HK-China, HK-UK, HK-Ireland, HK-Singapore, HK-Japan, HK-South Korea, and HK-UAE. Notably, Hong Kong does not have a CDTA with the United States.
Dividends: 5% for holdings of 25%+ (vs 10% standard PRC rate), 7% for below 25%. Interest: 7% (down from 10%). Royalties: 7%. Eligibility requires a valid Certificate of Resident Status, genuine beneficial ownership, and increasingly robust substance in the HK entity following the PRC SAT's tightened criteria.
A PE generally arises from a fixed place of business, an agent habitually concluding contracts, or construction/project activities exceeding defined thresholds (typically 6 or 12 months). Service PEs are present in many newer CDTAs. Post-MLI amendments have expanded PE definitions. Tax authorities aggregate related project durations to trigger thresholds.
The PPT within the MLI denies treaty benefits where one of the principal purposes of an arrangement was to obtain those treaty benefits — unless granting the benefit is consistent with the treaty's object and purpose. It requires genuine commercial substance in Hong Kong beyond merely accessing the treaty network.
Apply using Form IR1314 (corporations) or IR1316 (individuals). For corporations, the IRD assesses whether central management and control is exercised in HK — reviewing board composition, meeting locations, and where key decisions are made. Post-BEPS, the certificate alone is often insufficient; overseas authorities may require additional substance and beneficial ownership evidence.
