Bank of Thailand Exchange Control: What to Know When Transferring Money for Property
There's no cap on how much money can come into Thailand — but the larger the transfer, the more documents a bank will ask for. Here's how the Bank of Thailand's exchange control rules apply to paying for property.
Four thresholds worth knowing in advance:
| Threshold | What it governs | Requirement |
|---|---|---|
| No limit | Bringing money into Thailand | No cap on the amount |
| From $200,000 | Bank transfer | Bank requests supporting documents (unless KYB is already on file) |
| From $1,000,000 | Funds received | Mandatory repatriation and conversion to baht, or deposit in a foreign-currency account within 360 days |
| Cash over THB 450,000 or $15,000 | Physical entry/exit | Mandatory customs declaration |
Here's what's behind each threshold.
The baseline: no limit on bringing money in
Exchange control in Thailand is administered by the Bank of Thailand (BOT). The baseline rule for inbound transfers is simple — there's no cap on the amount:
But "no limit on the amount" doesn't mean "no paperwork." Two thresholds determine what documents a bank will require, both for the transfer itself and for converting it into baht afterward.
The USD 200,000 threshold: when supporting documents kick in
The first threshold applies to any bank or licensed agent handling the transfer:
In practice, that means for any transfer equivalent to USD 200,000 or more — a fairly common price point for a villa or several condo units — the bank will ask for documents explaining where the money came from and what it's for (a sale and purchase agreement or a developer's invoice, for example). Exactly which documents are required is up to the bank or authorized agent handling the transfer, based on the nature of the deal. This is the point covered in detail in FET, Credit Advice, and Chanote: a transfer like this typically concludes with an FET (for amounts from roughly USD 50,000 upward, as a matter of banking practice) or a Credit Advice being issued.
For amounts below this threshold, banks typically just require the client to declare the purpose of the transfer, without requesting supporting documents.
The USD 1 million threshold: mandatory conversion
For genuinely large sums, a separate requirement applies — this one to the recipient, not the sender:
For a property purchase at that scale — several units, or a large villa deal — this means the funds can't simply sit indefinitely in a foreign-currency account in Thailand: the rule requires either selling them for baht or placing them in a foreign-currency account within the set 360-day window.
Cash and customs declaration
A separate rule covers physically bringing cash in or out — relevant if part of the purchase price is planned to be carried in cash rather than sent by bank transfer:
For a property payment, these thresholds sit well below the total price of most deals — carrying an entire villa or condo purchase price in cash on a single trip isn't something that can be done without triggering a customs declaration. That's one of the reasons most transactions run through a bank transfer or a licensed currency exchange service rather than physically carried cash.
How this applies to paying for property
For a typical Thai property purchase, the practical takeaway is straightforward: the closer a transfer gets to USD 200,000 or above, the more complete a document package is worth preparing in advance — a sale and purchase agreement, a developer's invoice, and sometimes proof of the funds' origin. A bank or licensed agent can request these before processing the transfer, and not having them ready can delay a deal on a day when every hour counts.
This is where EXFM, as a licensed currency exchange service, helps a client prepare the transfer and the supporting documents ahead of time — so that by the time the deal is registered at the Land Department, the buyer already has the full package on hand, including an FET or Credit Advice.
