BEPS Pillar Two Compliance

From 2025, HK's Pillar Two minimum top-up tax ensures large MNCs (EUR 750M+ revenue) pay at least 15% effective tax in every jurisdiction including HK. Understanding GloBE rules and the HK QDMTT is now a compliance imperative.

⚠️

⚠ HK's 16.5% Rate Does NOT Automatically Mean 15% GloBE ETR

The GloBE Effective Tax Rate (ETR) calculation differs from the standard profits tax rate. Deferred tax timing differences, non-deductible items, and excluded income can push the GloBE ETR below 15% even for a company paying 16.5% headline profits tax — triggering a top-up tax obligation.

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？

GloBE ETR Calculation

The GloBE ETR is calculated jurisdiction-by-jurisdiction based on adjusted covered taxes / adjusted GloBE income — a complex calculation differing significantly from standard accounts.

⚠ Risk: Assuming HK ETR > 15% without calculation → missed top-up tax obligation

Substance-Based Income Exclusion

The SBIE reduces the top-up tax for genuine operations — 5% of payroll costs + 5% of tangible assets in each jurisdiction. Maximising SBIE requires understanding eligible costs.

⚠ Risk: Unclaimed SBIE → unnecessarily high top-up tax liability

GloBE Information Return

Large MNC groups must file a GloBE Information Return with each jurisdiction. In HK, this is filed with IRD. The return requires jurisdiction-by-jurisdiction ETR calculations and income/tax data.

⚠ Risk: Missed or incorrect GIR → penalties and regulatory scrutiny

QDMTT vs IIR Priority

HK's QDMTT (if enacted as qualifying) takes priority over the parent company's Income Inclusion Rule (IIR). Getting QDMTT qualification right avoids double collection of top-up tax.

⚠ Risk: Non-qualifying QDMTT → parent country also applies IIR → double top-up tax

Pillar Two applies to MNC groups with annual consolidated revenue of EUR 750M or more in at least 2 of the 4 preceding years. If your HK company is part of such a group, it is in scope. Standalone HK companies below this threshold are not directly subject to GloBE rules — but may be affected by their parent's QDMTT or IIR obligations.
HK enacted its Qualified Domestic Minimum Top-up Tax (QDMTT) effective from financial years beginning 1 January 2025. The QDMTT ensures that top-up tax on HK entities is collected by IRD (not by the parent company's jurisdiction). A qualifying QDMTT allows the HK top-up tax to reduce (safe harbour) the IIR/UTPR in the parent jurisdiction.
GloBE ETR = Adjusted Covered Taxes / GloBE Income (for each jurisdiction). Adjusted Covered Taxes are current taxes from accounts, adjusted for deferred taxes and excluded items. GloBE Income is accounting net income adjusted for permanent differences. The HK ETR calculation starts with profits tax paid but makes numerous adjustments.
The SBIE carves out a portion of GloBE income from the top-up tax calculation, based on genuine local operations. The exclusion is: 5% of eligible employee payroll costs + 5% of eligible tangible asset carrying values in each jurisdiction. Over time (2023-2032), these percentages phase down to 2.5% each. Groups with significant operations in HK benefit most from the SBIE.
The GloBE Information Return must be filed within 15 months of the last day of the reporting fiscal year (18 months for the transitional year). For a December 31, 2025 year-end, the GIR deadline would be June 30, 2027 (transitional) or March 31, 2027 (standard). HK IRD is expected to publish more detailed guidance on local filing mechanics.
No. The top-up tax is an addition to, not a replacement of, the standard HK profits tax. If HK profits tax results in a GloBE ETR below 15%, the top-up tax brings the total to 15%. If the ETR is already ≥15% (common for most active HK trading companies), no top-up tax applies. The most at-risk HK entities are those with significant tax incentives (patent box, offshore claims) that reduce the effective rate below 15%.
