What the rules actually say
1 · Residence
Vietnam tax residence can arise with 183 days or more of presence in a calendar year or relevant consecutive 12-month period, or under specified habitual residence or housing arrangements. Do not rely only on days.
2 · Income source
Resident individuals are generally assessed on relevant income earned in Vietnam and abroad; nonresidents on certain Vietnam-source income. The applicable classification, withholding and double-tax relief require checking.
3 · Important nuance
Vietnam's Law 109/2025/QH15 came into force on 1 July 2026; specified income-tax provisions for salaries and business income relate to the 2026 tax year. A guide using only the earlier seven-bracket system may be stale.
4 · Visas and exceptions
The US and Vietnam signed an income-tax treaty in 2015 but, according to 2026 treaty inventories, it was not yet in force; the signature alone does not grant treaty relief.
