Sending Money Out of Thailand — The Paperwork Banks Ask For, the Limits That Apply, and the Cheapest Routes for Expats Repatriating Savings
Bringing money into Thailand is easy; sending it out is where the rules bite. What Thai banks require to transfer baht abroad, why the source of the money matters, the transfer routes and what each costs, and how to plan a large repatriation.
Thailand has exchange controls. They are light for money coming in and noticeably heavier for money going out, because the rules exist to record where baht leaving the country came from. For an expat who has earned or saved in Thailand and now wants to move funds home, the transfer itself is routine; what takes time is producing the documents the bank is required to see.
What the bank will ask for
| Situation | Typical documents | Why |
|---|---|---|
| Sending back money you originally brought in | The inbound transfer record or foreign exchange form from when it arrived | Proves the funds are foreign-origin, which has the fewest restrictions |
| Sending salary earned in Thailand | Work permit, employment contract or payslips, and a tax record | Shows the income was legal and taxed |
| Sending proceeds from selling property | Sale contract, title transfer record, and evidence the purchase money came from abroad | Property purchases by foreigners must be funded from abroad, and the outbound transfer is matched against that |
| Sending money as a gift or for family support | Identification of the recipient and a stated purpose | Purpose codes are recorded for every outbound transfer |
Keep the foreign exchange transaction form or transfer confirmation from every inbound transfer above the bank's reporting threshold. Years later it is the single most useful document for getting the money back out.
The routes and what they cost
- Bank international transfer (SWIFT): the standard route for larger amounts and the only one for some purposes. Cost is a fixed fee plus the bank's exchange margin, with a possible receiving fee at the other end. Rates improve for larger amounts if you ask the branch.
- Specialist transfer services: several licensed providers now move baht abroad at close to mid-market rates with lower fees, subject to limits per transfer and per year, and with the same documentation for larger amounts. They are usually cheapest for mid-sized regular transfers.
- Carrying cash: legal within declared limits, but the exchange margin on baht abroad is poor and the risk is yours.

Planning a large repatriation
Talk to your branch before you need the money moved. Ask which documents they want for your specific source of funds, whether a tax clearance or certificate of income will be required, and what exchange rate they will offer for the amount. Move the money in a small number of larger transfers rather than many small ones, which look like structuring and attract questions. Expect the first transfer to take days while documents are checked; later ones are faster.
Tax interactions
Sending money abroad is not itself taxable in Thailand, but the income it came from may be, and the bank's request for tax records is where undeclared income surfaces. The basic rules on what Thailand taxes are covered in Thailand tax basics for expats; if you have been in Thailand long enough to be tax resident, get the filing right before the transfer, not after.
Common mistakes
- Losing the inbound transfer records. Without them, even your own money is treated as Thai-source and needs more paperwork.
- Using a friend's account or an informal broker. Unlicensed transfers are illegal and unprotected.
- Trying to send everything in one rushed week before leaving. Start months ahead.
Summary
Money leaves Thailand on evidence: keep the record of every inbound transfer, match outbound transfers to a documented source, use a bank or licensed transfer service, and plan large repatriations with your branch well before departure. The rules are manageable; surprises come only from missing paperwork.
