Is there a Korea–Thailand tax treaty?

Yes — Korea appears in Thailand's Revenue Department list of in-force double taxation agreements. We have filed the network confirmation; article-level cascade text (Art 4 tie-breaker) is deliberately not yet filed for this pair.

Why is Art 4 not filed yet?

Product honesty. We do not invent article numbers or cascade text without reading the convention line by line. The live Korea–Vietnam pair has Art 4 filed; this Thailand overlay will get the same treatment once the text is sourced.

How does Thailand's remittance rule interact with the treaty?

Thailand taxes residents on foreign income when it is remitted into the country (Revenue Code §41). Treaty relief must be read against that remittance hinge — do not assume worldwide Thai tax without checking what you actually brought in.

Do Korea-side traps still apply?

Yes. The 183-day residence limb that can span two tax years, exit tax, and SSA/NPS rules are Korean domestic rules. Moving to Thailand does not switch them off.

South Korea → Thailand · tax

In plain termsTwo machines, one remittance hinge. Thailand counts days and remittances; Korea keeps exit tax and the 183-day span. Korea is in Thailand's DTA network — but we have not yet filed the Art 4 cascade for this pair.

There is a treaty — in the RD in-force network

Korea–Thailand income tax treaty is in the RD in-force network (yes). Compare the live beachhead pair — where Art 4 is filed: South Korea → Vietnam · tax.

Art 4 cascade — deliberately not yet filed

Product honestyArt 4 tie-breaker text is deliberately not yet filed for Korea–Thailand (yes). Do not copy the Vietnam cascade onto Thailand. When the convention text is read line-by-line, this page will get the same article-level cells as the live pair.

The remittance hinge

Client trapThailand's remittance basis interacts with this pair's DTA relief (yes). Thailand's residence door is 180 days in a calendar year, with foreign income taxed on remittance (yes) — read Thailand tax residency.

Korea-side traps — destination does not delete them

Korea domestic traps still apply when Thailand is the destination (yes): 183-day residence limb spanning tax years, exit tax, and SSA/NPS rules. The income DTA narrows double tax; it does not cancel your Korean obligations.

How it stacks with Thai law

Thailand taxes a resident (≥180 days) on Thai-source income and on foreign income remitted into Thailand — read the destination pillar: Thailand tax residency. Korea may still tax you as a resident or on exit; treaty relief keeps the same won from being taxed twice, but never removes the second filing.
