Pick a year, the entity (company or household business) and the filing periods, and get every tax deadline falling in that year: monthly returns on the 20th, quarterly returns on the last day of the following month, provisional CIT on day 30, annual CIT / PIT finalisation and financial statements at the end of the 3rd month after the fiscal year, individual PIT finalisation at the end of April, and the household-business calendar of NĐ 68/2026/NĐ-CP.
Every date that falls on a weekend or a public holiday is moved to the next working day (NĐ 252/2026/NĐ-CP Điều 3), using the official day-off schedules of our Vietnamese holiday calendar; moved_because says why. The business licence fee (due 30/1) is only listed up to 2025: it was abolished from 1/1/2026 by Nghị quyết 198/2025/QH15.
extension=true adds the payment deadlines extended by NĐ 245/2026/NĐ-CP for eligible taxpayers. month and upcoming=true filter the list, and format=ics returns a calendar file with a reminder 3 days before each deadline.

FAQ
What happens when a deadline is a Sunday or holiday?
It moves to the next working day; the answer keeps the statutory date and gives the reason (e.g. Chủ nhật, Quốc khánh).
Is the licence fee (lệ phí môn bài) still listed?
Only for years up to 2025. Nghị quyết 198/2025/QH15 ended the licence fee from 1/1/2026.
Are extensions included?
With extension=true for 2026, the extended payment dates of NĐ 245/2026/NĐ-CP are added; filing deadlines do not change.
