Quick answer
Under Article 1 of Circular 111/2013/TT-BTC, an expat is classified as a Vietnam tax resident if present in Vietnam for 183 days or more in a calendar year or 12 consecutive months from first arrival. A secondary accommodation test applies if you hold a registered residence or lease agreement of 183+ days, unless you prove tax residency in another jurisdiction.
Tax residents are subject to progressive tax rates (5%–35%) on worldwide income with full entitlement to personal and dependant deductions. Non-residents pay a flat 20% withholding rate on Vietnam-source earnings without allowances.

The 183-day tests
Under Article 1, day counting strictly adheres to entry and exit stamps: * Calendar Year Test: Present in Vietnam for $\ge 183$ days between January 1 and December 31. * 12-Month Consecutive Test: Present for $\ge 183$ days within 12 consecutive months from the date of first arrival in Vietnam. * Presence Rules: Arrival and departure dates both count as 1 full day of physical presence. Retain all passport immigration stamps as audit evidence.
Accommodation and habitual residence
If physical presence is fewer than 183 days, you may still be classified as a tax resident if you maintain a "regular residence": * A registered permanent residence under residency laws, or * Rented living premises (including serviced apartments or residential houses) with a cumulative lease term of 183 days or more within the tax year.
Exception: If you maintain a 183+ day lease in Vietnam but spend fewer than 183 physical days in the country and can present an official Tax Residency Certificate (TRC) issued by your home country, you are treated as a non-resident.
