A German investor putting capital into Viet Nam: how many times are repatriated profits taxed? The Viet Nam–Germany double taxation agreement (signed in 1995) answers by dividing taxing rights between the two states — but only if businesses check the right article and follow the right procedure.
1. Germany–Viet Nam cash flows and how the treaty divides them
Typical flows: a Vietnamese subsidiary pays dividends to its German parent; a Vietnamese company pays technology royalties and loan interest to German counterparts; German experts working in Viet Nam earn salaries. The treaty provides: business profits taxable only in the residence state, unless a permanent establishment (PE) exists in the other state; dividends, interest and royalties face source-state withholding at treaty-reduced rates — below domestic rates. Each income type gets its own article; there is no “single rate for every payment to Germany”.
2. German investors’ special feature: PE and substance
German businesses typically post many experts to Viet Nam and keep long-term project offices — a configuration prone to constituting a PE in Viet Nam (prolonged construction or installation projects; consultancy performed in Viet Nam). With a PE, Viet Nam taxes the attributable profits. Conversely, a Vietnamese company selling into Germany through a dependent agent signing contracts can create a German PE. Cross-border presence must be PE-designed from the start — a silently “grown” PE is the costliest structural error.
3. Procedures and the double-tax relief mechanism
To apply treaty rates: in Viet Nam complete relief procedures under current tax administration law (Law on Tax Administration 108/2025/QH15, effective 01/7/2026) with the German counterpart’s tax-residence certificate; in Germany follow the German tax authority’s procedures. When the two states interpret differently (e.g. PE profit attribution), the treaty’s mutual agreement procedure (MAP) lets the two authorities negotiate. Every concrete tax computation needs an adviser’s review.
Conclusion
The Viet Nam–Germany treaty does not automatically cut tax — it is a map dividing taxing rights. German investors who can read the map (right article, right procedure, right PE) never pay tax twice on the same profit.
