Practical Context
Thailand and Vietnam are major ASEAN trading partners, and the DTA has been in force since 1993. Thai companies investing in Vietnam, particularly in food processing, retail, and manufacturing, rely on the treaty. Thai expats working in Vietnam are also covered. The 15% royalties rate is higher than some other treaties but reflects the ASEAN-ASEAN negotiation dynamic.
Key Treaty Provisions Explained
Dividends
10% capWhen a Vietnamese company pays dividends to a Thailand shareholder, Vietnam withholds 10% under this treaty — compared to Vietnam's standard domestic rate which may be higher. This applies to portfolio investors. Substantial shareholders may qualify for even lower rates in some treaties.
Interest
10% capInterest paid by a Vietnamese borrower to a Thailand lender is subject to a maximum 10% withholding tax under this treaty. This is relevant for intercompany loans between Thailand parent companies and Vietnamese subsidiaries, as well as bonds and other debt instruments.
Royalties
15% capRoyalties paid from Vietnam to Thailand for use of IP (patents, trademarks, software, know-how) are capped at 15% withholding tax. This rate applies to all qualifying royalty payments under the treaty.
Frequently Asked Questions
Does Vietnam have a tax treaty with Thailand?
Yes. Vietnam and Thailand have a Double Taxation Agreement (DTA) that has been in force since 1993. The treaty prevents the same income from being taxed in both countries and sets withholding tax caps on dividends, interest, and royalties.
What is the withholding tax rate on dividends under the Vietnam–Thailand DTA?
Under the Vietnam–Thailand DTA, the withholding tax on dividends is capped at 10%. Without a treaty, Vietnam's standard domestic WHT rate on dividends paid to foreign entities is generally higher. Always confirm the applicable rate with a tax adviser, as lower rates may apply if specific shareholding thresholds are met.
How does the Thailand–Vietnam DTA affect my salary as an expat?
Under Article 15 of the Vietnam–Thailand DTA, employment income is generally taxable in Vietnam if you are working in Vietnam. The treaty's tiebreaker rules determine your residency: Tiebreaker proceeds through permanent home, vital interests, habitual abode, and nationality. If you are a Vietnamese tax resident, your worldwide income may be subject to Vietnam PIT, with a credit or exemption for taxes paid in Thailand.
What is a Permanent Establishment (PE) under the Vietnam–Thailand treaty?
A Permanent Establishment is a fixed place of business through which a Thailand company carries on business in Vietnam. If a PE exists, Vietnam can tax the profits attributable to it. Common PE triggers include offices, branches, factories, construction sites lasting more than 6 months, and dependent agents. Thailand companies operating in Vietnam should assess PE risk carefully.
