IRAS expands automatic exchange of CbC reports to include Armenia, Montenegro, Mongolia, Serbia, and Vietnam, reinforcing Singapore’s BEPS Action 13 compliance measures.
The Inland Revenue Authority of Singapore (IRAS) updated its Country-by-Country (CbC) Reporting guidance on 6 March 2026, revising the list of jurisdictions with which CbC reports can be automatically exchanged.
| Jurisdiction | Effective Financial Year (FY) |
| Armenia | FY 2025 |
| Montenegro | FY 2024 |
| Mongolia | FYs beginning 1 Dec 2023 |
| Serbia | FYs beginning 1 Dec 2023 |
| Vietnam | FYs beginning 1 Dec 2023 |
Singapore-headquartered multinational enterprise (MNE) groups that meet certain requirements must prepare and file CbC Reports to IRAS for FYs beginning on or after 1 January 2017, within 12 months from the end of their FY. CbC Reporting is a form of reporting initiated by the OECD under the Base Erosion and Profit Shifting (BEPS) Action 13 framework.
For FYs beginning on or after 1 January 2022, Singapore MNEs are also required to notify IRAS of their CbC filing obligation within three months from the end of the relevant FY. These updates reflect Singapore’s continued commitment to implementing BEPS measures.
