Can an Expatriate Be Taxed in Both Vietnam and Their Home Country?
Yes, potentially — both countries' domestic tax rules can apply to the same income. That doesn't automatically mean the income ends up taxed twice: where Vietnam has a Double Taxation Agreement with the other country, the treaty can allocate taxing rights, limit one country's claim, or provide relief such as a foreign tax credit.

Two Countries, One Question Worth Untangling
A Vietnam tax resident being taxed on worldwide income can genuinely overlap with their home country also taxing the same income under its own domestic rules. Whether that turns into actual double taxation — paying full tax twice on the same money — depends on whether a treaty applies and how it's structured, not on the overlap alone.
Why Double Taxation Isn't Automatic
Where Vietnam has a Double Taxation Agreement (DTA) with the other jurisdiction, the treaty can do one or more of the following: allocate taxing rights between the two countries for a given type of income, limit one country's right to tax it, or provide double-tax relief such as a foreign tax credit for tax already paid elsewhere. Nationality alone doesn't determine the result — the specific treaty and the specific income type do.
How the Analysis Actually Works
The right sequence works through several factors in order, not a single rule applied uniformly to every country.
- Tax residency — which country (or both) has a claim
- Income source — where the income is considered to arise
- Where employment is actually exercised
- Each country's own domestic tax rules
- The specific Double Taxation Agreement that applies, if one exists
- Available double-tax relief under that treaty
