Scenario: a Vietnamese company pays USD 200,000/year in technical service fees to a Singapore company (remote plant support plus short expert visits). Accounting proposes “claiming treaty relief” — but does the Vietnam–Singapore treaty even have a technical-fees article?
The short answer: the treaty has no dedicated technical-fees “door”
The Vietnam–Singapore DTA (1994, 2012 protocol) has no separate technical service fees article (commonly published position — verify against the treaty text before concluding). Pure technical service fees fall under Article 7 (business profits): Singapore is taxable in Vietnam only with a permanent establishment (PE) in Vietnam. No PE → Vietnam may not tax under the treaty → domestic FCT (5% VAT + 5% CIT) cannot apply. Sounds good — but “no PE” must be evidenced, not merely asserted.
Trap 1: technical fees recharacterized as royalties
Vietnamese tax authorities may recharacterize “technical service fees” as royalties where the substance is transferring know-how or licensing patents/software — then Article 12 applies (10% cap, commonly published) with 10% domestic FCT on royalties. The distinction: technical services = doing it for you (engineers fixing machines on site); royalties = letting you use it (transferring formulas, software licenses). A contract labeled “technical service fee” whose content is know-how transfer will almost certainly be recharacterized.
Trap 2: extended expert presence becomes a service PE
If Singapore experts are present in Vietnam over extended periods (service project exceeding the treaty’s time threshold — commonly published), the Singapore company may be deemed to have a service PE — then Article 7 “opens the door” for Vietnam to tax PE-attributable profits, collapsing the entire “no PE, no tax” argument. Managing expert presence (days, project continuity) is legal’s job, not admin’s.
Bottom line for decision-makers
For VN → Singapore technical fees: step 1 is correct characterization (pure services vs royalties) — rewrite the contract to match substance before discussing tax; step 2 is controlling expert presence to avoid a service PE; step 3 is the treaty file (Singapore COR + no-PE evidence). This order cannot be reversed: wrong characterization voids every treaty paper.
Frequently Asked Questions
Does the Vietnam–Singapore DTA have a technical-fees article?
No separate article (commonly published). Pure technical service fees fall under Article 7 (business profits): with no Vietnamese PE, Vietnam may not tax.
What is domestic FCT on service fees?
Current frame: 5% VAT + 5% CIT on service fees (CIT Law 67/2025 + Decree 320/2025 + Circular 20/2026; the contractor-CIT part of Circular 103/2014 was repealed from 12/3/2026) — but inapplicable where the treaty yields 0% (no PE).
When are technical fees treated as royalties?
When the substance is transferring know-how/technology use rights (letting you use it) rather than performing work — then Article 12 (10% cap) and 10% royalty FCT apply.
What is a service PE and how to avoid one?
A service permanent establishment: extended expert presence beyond the treaty threshold creates a PE — control visit days and project continuity; do not let admin schedule blindly.
