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.

Frequently Asked Questions

How many business days are in January 2030 for Vietnamese national?

The month spans 31 calendar days, of which 8 fall on a weekend and 0 are Vietnamese national holidays that lands on a weekday.

Which Vietnam holidays affect January 2030?
January 2030 contains no Vietnamese national holidays that fall on a weekday. Banks, the central clearing system, and Vietnam financial markets keep their normal schedule throughout the month under this calculator's national-only holiday set.
How long is the Tet closure each year?
Tet (Lunar New Year) is Vietnam's longest national closure, gazetted by the Government annually under Article 112 of the Labour Code 2019. The official statutory closure is 5 days but the Government typically pulls in adjacent weekends to create a 7-9 day national holiday, sometimes longer. Make-up working Saturdays after Tet are gazetted to balance the calendar year. Banks, the HOSE and HNX stock exchanges, and government offices all close. This calculator uses the most-commonly observed 7-9 day window based on the prior year's gazette where the next year's notice has not been published.
When is Hung Kings Commemoration Day?
Hung Kings Commemoration Day (Giỗ Tổ Hùng Vương) falls on the 10th day of the 3rd lunar month and honours the legendary founders of Vietnam. The Gregorian date varies each year, typically in early to mid-April. It became a national public holiday in 2007 and closes banks, the HOSE/HNX, and government offices. When the lunar date falls on a weekend, the Government may declare an in-lieu Monday by decree but this is not automatic.
Why does the business-day count vary year to year?
Two things shift the monthly count for Vietnam. First, the day of the week the first of the month lands on changes the count of each weekday. Second, Vietnamese national holidays anchored to a fixed date shift their weekday across years. Some years a fixed-date holiday lands on a weekend; some countries shift the observance to an adjacent weekday and some absorb it into the weekend. January 2029 had 22 working days, so January 2030 has 1 more working day year over year.
