How the 183-day rule works in Vietnam
Vietnam counts 183 days in any consecutive 12-month period from the date of first arrival.
Rolling 12-month window. This means the count looks back from any given date, not just the calendar year boundary. A rolling window is harder to track manually because the number changes every day.
If you exceed 183 days, Vietnam may tax your worldwide income as a tax resident. The exact consequences depend on your personal situation, any applicable tax treaties, and the type of income involved.
