Scenario: a Vietnamese company pays USD 1 million in dividends to its Thai parent. Vietnam withholds nothing (0%), but Thailand taxes the inbound dividend — can the treaty reduce tax on the Thai side, and what does the file contain?
The Vietnam–Thailand DTA’s signature: a flat 15% cap
Unlike treaties with ownership-tiered caps, the Vietnam–Thailand DTA (1992) sets a flat 15% cap on dividends in Article 10 (verified against the treaty full text at rd.go.th — the Thai Revenue Department site) — no 10% tier for large shareholders as in the Philippines treaty. Article 11 (interest) and Article 12 (royalties) cap at the commonly published 15% (verify against the treaty text). For Vietnam → Thailand: Vietnam’s 0% domestic rate leaves the treaty nothing to do on the Vietnamese side; the treaty’s value sits on the Thai side — when the Thai parent declares the Vietnamese dividend, the treaty limits taxing rights and allows credit for tax paid.
Dossier checklist: the Thai residence certificate at the center
For treaty application on the Thai side, the parent needs: (1) a Certificate of Residence from Thailand’s Revenue Department — proving Thai-resident treaty entitlement; (2) dividend evidence (distribution resolution, Vietnam remittance records); (3) proof of tax paid in Vietnam (if any — at 0% dividends the remittance record suffices); (4) beneficial-ownership documents if the Thai authority asks. On the Vietnamese side (for FCT-bearing items like royalties/interest): the Circular 80/2021/TT-BTC file via the Vietnamese payer — Thai COR + contracts + claim letter.
The trap: filing in the wrong direction
The common error: companies file to “reduce Vietnamese withholding” on Vietnam → Thailand dividends — while Vietnam is already at 0% with nothing to reduce. The treaty file for these dividends belongs on the Thai side (where inbound-dividend income is taxed), not the Vietnamese side. Conversely, for Vietnam → Thailand royalties/interest (Vietnamese FCT 10%/5%), the file belongs on the Vietnamese side under Circular 80/2021. Each direction has its filing place — wrong direction wastes time.
Bottom line for decision-makers
For Vietnam → Thailand dividends: skip Vietnamese filings (already 0%); focus the file on the Thai side to optimize the parent’s income tax. For reverse royalties/interest: the Circular 80/2021 checklist in Vietnam with a Thai Revenue Department COR. The rule: the treaty file is filed where tax is levied, not where 0% is paid.
Frequently Asked Questions
What is the dividend cap under the Vietnam–Thailand DTA?
Article 10 sets a flat 15% cap (no ownership tiers like the Philippines treaty) — verified against the full text at rd.go.th.
Is a Vietnamese-side treaty file needed for Vietnam → Thailand dividends?
No — Vietnam already withholds 0% on corporate dividends. The treaty file belongs on the Thai side (where inbound-dividend income is taxed).
What does the Thai-side file contain?
Revenue Department Certificate of Residence; dividend evidence (resolution, remittance records); proof of Vietnamese tax paid (if any); beneficial-ownership documents if requested.
What is the common two-direction DTA filing error?
Wrong direction: seeking withholding reduction where the rate is already 0% instead of where tax is levied — file where tax is levied.
