Vietnam reporting cycles and business-day rules
Vietnamese business-day cycles align with GDT (General Department of Taxation) monthly VAT returns due by the 20th of the following month, quarterly corporate income tax provisional payments due 30 days after each quarter-end, and the annual CIT finalisation due the last day of the 3rd month after fiscal year-end. The State Bank of Vietnam operates VICAS as the high-value RTGS system on bank business days. Tet (Lunar New Year) closes banks and the HOSE/HNX for 7-9 days under the annual Government decree. The Labour Code 2019 governs employment including the 13th-month salary norm and Tet-related leave entitlements. The Ministry of Planning and Investment (MPI) approves FDI projects.
