Carrying cash from Malaysia to Thailand
Two separate rules apply to any cash journey: one where you leave, one where you arrive.
Do you need to declare?
Yes: and on both legs of the journey. Leaving Malaysia, Royal Malaysian Customs Department requires a declaration above USD 10,000. Entering Thailand, Bank of Thailand (exchange control) requires a declaration above THB 450,000. The two rules are independent: satisfying one does not satisfy the other.
The two legs
| Leg | Limit | Form | Authority |
|---|---|---|---|
| Leaving Malaysia | USD 10,000 | Customs Form No. 7 (K7), Declaration of Cash and Bearer Negotiable Instrument | Royal Malaysian Customs Department |
| Entering Thailand | THB 450,000 | no form | Bank of Thailand (exchange control) |
The same threshold applies on departure. The declaration is required under section 23 of the Anti-Money Laundering and Anti-Terrorism Financing Act 2001, not under customs duty rules, so it applies whatever the money is for.
No limit applies to bringing baht or foreign currency into Thailand. A customs declaration is required above THB 450,000, or above USD 15,000 in foreign currency banknotes.
If you do not declare
Malaysia: A fine of up to RM1 million and/or imprisonment of up to one year for failing to declare or making a false declaration.
There is no limit on how much you may legally carry in either direction, the duty is to report it, not to keep under it. Failing to report is the offence.
Currencies
Malaysia uses MYR; Thailand uses THB.
