USD to Thailand: Transfer Guide for US Buyers

Currency Transfer Guide for US Buyers: Moving USD to Thailand

Many Phuket developers quote prices in US dollars, which fixes what an American pays through an off-plan schedule in the currency they earn. It does not fix what they own: the unit, the rent and the resale are in baht, and the money still has to cross into Thailand as dollars and be converted there. This page is about that crossing, and the one document it produces, which the proof of funds guide explains in general terms for every nationality.

USD Pricing in Phuket: A Significant US Buyer Advantage

Your contract is denominated in USD
Payment milestones are in USD amounts (not THB)
Currency fluctuation risk is reduced (you’re not converting to THB until settlement)
Rental income may also be quoted in USD (especially managed hotel pools)

Some branded and luxury developers quote in dollars and many mid-market and domestic developers quote in baht. Ask, and then read the conversion clause: a dollar contract is usually still settled in baht at the Land Department at a rate applied on the day, and whose rate that is matters.

What the dollars have to cover once they are baht

The transfer is sized by the contract, and the baht costs around it are sized by Thai law, on the government-appraised value rather than on the price you paid. At registration the Land Department charges a 2% transfer fee, commonly split between buyer and seller by agreement; the seller carries specific business tax at 3.3% if the unit was held under five years or stamp duty at 0.5% after, plus withholding of 1% to 3.3% for an individual seller, and all of it is payable on the day, per the condo transfer fees guide. Once the unit is let, 15% is withheld at source from the rent of an owner in Thailand fewer than 180 days a year, per the rental income tax guide, and the common-area charge and the annual land and building tax, at 0.02% of assessed value for residential use, are billed in baht. None of these is fixed by a dollar contract, so the account you open for the purchase is the account that will pay them, in baht, for as long as you own the unit.

What USD pricing does and does not remove

A developer quoting in dollars removes one layer of uncertainty, and it is worth being precise about which layer, because buyers often assume it removes more than it does.

What it removes: the risk that the purchase price itself moves against you between agreeing a deal and paying for it. If the contract says $300,000, that is what you owe regardless of where the baht goes.

What it does not remove: everything after the purchase. Transfer fees are calculated on the registered value in baht. CAM, sinking fund and the annual land and building tax are baht costs. Rental income arrives in baht. The eventual sale will most likely be priced in baht or negotiated against baht comparables. So a dollar-priced purchase still leaves you holding a baht-denominated asset with a baht-denominated income stream.

There is also a practical detail worth checking rather than assuming: a contract priced in dollars is usually still settled in baht at the Land Department, at a rate applied on the day. Ask which rate the contract specifies, whose rate it is, and on what date it is fixed. A dollar price converted at an unfavourable in-house rate is not the same as a dollar price, and the difference on a large purchase is real money.

None of this argues against dollar pricing, which is genuinely convenient. It argues for reading the conversion clause with the same attention as the price.

Step-by-Step: Transferring USD for a Phuket Property Purchase

Step 1: Open a Thai account in your own name

The record has to be issued in the name that will appear on the title, so the money goes to an account of yours, not to the developer’s and not to an escrow account. Opening one as a non-resident takes longer than buyers expect and varies by bank and branch; start at reservation, not at the first milestone.

Step 2: Get Competitive Transfer Quotes

On the day you want to transfer, compare the all-in cost, the exchange rate spread plus the fee, from your bank and from at least one specialist provider. No spreads are quoted here because they change daily and nobody on this project monitors them; on a purchase-sized sum the difference between routes is real money, and it is visible in a five-minute comparison.

Step 3: Initiate the Transfer via Your Chosen Service

Provide your Thai bank account details (account number, SWIFT code, bank name and branch address)
Your bank or the specialist provider sends US dollars by SWIFT; confirm before sending that the route delivers foreign currency to your Thai account rather than baht
Some developers accept dollars into their own accounts; understand before using that route that the record may then be issued in the developer’s name

Step 4: Receive the FET Certificate

When your dollars arrive at your Thai bank and are converted to baht:

The bank issues the Foreign Exchange Transaction record for inbound wires of roughly $50,000 and above; below that threshold you receive a credit advice, and you have to ask for it
This is your proof that the funds originated overseas in foreign currency, in your name, for the property
Keep the originals; a bank that has changed its systems cannot reissue a record from years ago

A caution on paying the developer directly in dollars. Where a developer holds a dollar account at a Thai bank and you wire to it, the bank records the developer as the recipient, and the document that reaches the Land Department may not carry your name. A payment can complete the purchase and still fail to produce the record that registers it; have your lawyer confirm the paper trail before choosing that route.

Step 5: Payment to Developer / Land Department

Transfer THB from your Thai account to the developer’s account
Or bring certified THB bank drafts to the Land Department on registration day
Retain proof of all payments in THB

Work through these in order, and start each one earlier than feels necessary.

FBAR Considerations: Thai Bank Account Reporting

FinCEN Report 114 (FBAR):

File electronically via the BSA E-Filing System
Deadline: April 15, auto-extended to October 15
Reports the maximum balance, not just year-end balance
Penalties for non-filing are severe relative to the balances involved, and criminal exposure exists for willful failure

For a typical property purchase: Your Thai account will almost certainly hold more than $10,000 during the transfer period, making FBAR mandatory. This is a reporting obligation only, no additional tax is owed.

The $10,000 is an aggregate across every foreign account you hold, not a per-account figure, and the test is the peak balance on any day of the year, not the balance on 31 December.

Forward Contracts: Locking in Today’s USD Rate

Options:

Forward contract (OFX, corporate FX brokers): Lock today’s USD/THB rate for future transfer
Limit order: Set a target rate and transfer executes automatically
Natural hedge: If your property earns USD-denominated rental income, this reduces your ongoing currency exposure

For a property priced in dollars, a dollar-based buyer carries little exchange risk on the purchase price itself; the exposure sits in the baht costs of ownership and in the baht value of the asset at exit.

When a forward is worth it, and when it is not

A forward contract fixes an exchange rate today for a payment on a known future date. It removes uncertainty; it does not remove cost, since the pricing is built into the rate you are quoted.

It is worth considering when the date is genuinely known and the sum is large enough that a move would matter: a completion date on a resale purchase, or a defined off-plan milestone. It is worth less when the date is uncertain, because an off-plan milestone that slips leaves you holding a contract to buy baht on a day you no longer need them, and unwinding that has its own cost.

That last point deserves weight given how often Thai off-plan runs late. A forward against a milestone that historically slips six to eighteen months is a hedge against currency risk that introduces timing risk in its place.

The alternatives are simpler and suit most private buyers. Converting the full amount early and holding baht removes the exposure entirely, at the cost of committing to today’s rate and forgoing any favourable move. Converting per tranche accepts the movement and requires no instrument at all.

Whichever you choose, the discipline that matters more than the instrument is deciding once, at the outset, rather than making the decision again at every milestone under whatever the rate happens to be that week. Buyers who drift into per-tranche conversion by default usually did not choose it; they simply never chose.

Repatriating Funds When You Sell

Taking money out of Thailand is governed by what you can document putting in, which is why the filing you do at purchase is really about the sale.

The basic rule. Foreign currency brought in and recorded on the way in can be sent back out. The record (issued by the receiving Thai bank, in your name, stating the purpose) is the evidence. Without it, the sale proceeds are baht in a Thai account and the route out is narrower and slower.

What this means in practice. Keep every certificate from every transfer, permanently, along with the original purchase documents. A record from eight years ago cannot be reissued by a bank that has since changed its systems, and the owner producing a title deed but not a currency record at sale is a routine and expensive scene.

The tranche problem. An off-plan purchase paid in several transfers needs a record for each. One tranche sent from a spouse’s account, or converted to baht before sending, or described as something other than the property purchase, is a gap in the chain, and the gap is discovered years later, when the money is going the other way.

What is not covered. The gain, and any rental income accumulated in Thailand, sit outside the amount you brought in. Moving those follows a different route and is worth asking your Thai bank about before you need it rather than at the point of sale.

The US layer. Repatriation is a Thai mechanic; the tax consequence is American, and it is computed in dollars. The exchange rate on the day you bought and the day you sold both enter the calculation, which means a property that gained in baht can produce a different figure entirely on a US return.

Why the paperwork you file today matters at exit

Thailand does not restrict a foreign owner from repatriating sale proceeds, and the process is materially smoother where the original inbound funds were documented correctly.

The FET created at purchase establishes that the money came from abroad in foreign currency. Years later, when you sell, that record is what makes the outbound transfer straightforward rather than a matter of assembling evidence retrospectively.

This is the strongest practical argument for treating the transfer documentation as part of the purchase rather than as an administrative afterthought. It is needed twice: once to register the title, and once by whoever handles the sale, potentially a decade later when everyone involved has forgotten the details. Keep the FET with the title documents, not in an email folder.

On the American side, keep the acquisition records too. Your cost basis in dollars is what determines the gain when you sell, and it depends on the exchange rate at the time of each payment. On an off-plan purchase paid in several tranches at different rates, reconstructing that later without contemporaneous records is genuinely difficult, and it is the number your return will turn on.

The four things that must be right on every transfer

Freehold registration by a non-resident depends on documentation created at the moment the money arrives, and it cannot be reconstructed afterwards. Four details decide whether it works.

Detail	Requirement	What goes wrong
Sender name	Must match the buyer who will appear on the title	Funds sent by a spouse, a trust, an LLC, or a differently spelled name
Amount	Must cover the purchase price	Sending net of wire charges, leaving a shortfall at registration
Currency	Foreign currency, converted by the Thai bank	Converting to baht in the US, so there is no inbound foreign remittance to record
Purpose	Referencing the property purchase	A blank or generic reference the bank cannot amend later

The currency row defeats more American transactions than the other three combined, because the instinct is to lock the rate at home. Send dollars and let the Thai bank convert.

Costs and timing, compared

Route	Typical cost	Speed	Suitable for the purchase funds?
Bank wire, USD	Wire fee plus the bank’s FX spread	3-5 business days, longer with compliance checks	Yes, and it produces clean documentation
Specialist FX provider	Tighter spread, explicit fee	Similar	Usually, but confirm the receiving path supports FET issuance
Forward contract	Priced into the rate	Settles on the agreed date	Yes, for a known milestone date
Consumer transfer apps	Cheapest headline	Fast	Only for small sums; confirm documentation first
Cryptocurrency conversion	Variable	Fast	No. It creates FET documentation problems that surface at registration

Allow ten working days before any milestone. Enhanced compliance checks add days rather than hours, particularly on larger sums, and a late tranche on an off-plan schedule can trigger a penalty clause.

US-side obligations that arrive with the account

Opening a Thai bank account makes receiving rent and paying CAM straightforward, and it is a foreign financial account. It counts toward the FBAR aggregate threshold alongside any other foreign accounts you hold, and the obligation attaches whether or not the account holds much. Tell your accountant before the first filing rather than after.

The same applies to the property itself under FATCA thresholds, and to Thai rental income on your US return, where foreign tax credit relief generally prevents double taxation but requires filing to claim. None of this is onerous; all of it is cheaper to set up correctly than to regularise later.

Buyer scenarios and decision framework

Scenario A, a resale priced in baht, completing in a single payment: one wire in the week before closing, from your own account, in dollars, with the lawyer confirming that the record will be in hand on registration day. Get all-in quotes from two routes that morning; the gap between them on a purchase-sized sum is the largest saving available anywhere in the transaction.

Scenario B, an off-plan schedule over two years: one record per instalment, all from the same sender, with the same stated purpose. Decide once whether you convert per tranche, convert early and hold baht, or buy forward against milestone dates that may slip, and write the decision down so you do not remake it under each month’s rate.

Decision framework: (1) Compare all-in cost (spread + fees), not headline rate. (2) Open Thai account before reservation if developer requires local payment. (3) File FBAR if balance exceeds $10k any day in calendar year. (4) Cross-read currency risk guide for off-plan exposure.

Match yourself to one of these before choosing a transfer route, since the right answer differs by sum and by timing.

Closing week coordination

Land Department day often requires certified bank drafts or same-day THB availability, pre-position funds 48 hours early. Last-minute Wise transfers on closing morning fail when Thai banks cut off SWIFT processing mid-afternoon local time.

The week itself is straightforward if the FET is already correct and the power of attorney, where needed, has been notarised and legalised well in advance. Both are the items that slip, and both run on timetables outside Thailand that cannot be accelerated once the transfer date is set.

Frequently Asked Questions

Can I pay for a Phuket property in US Dollars?

Often yes. Many Phuket developers, especially luxury and branded residence projects, price in USD and accept USD payments. Your funds are then converted to THB by the Thai bank and a FET certificate issued. Some developers even hold USD-denominated accounts. Check your specific developer's payment terms.

Should I convert my dollars to baht before sending them to Thailand?

No. The Land Department registers a foreign freehold on the strength of the Thai bank's record that foreign currency arrived and was converted onshore. Dollars converted in the United States arrive as baht, nothing is recorded, and the registration stalls. Send dollars, let the Thai bank convert, and compare all-in cost between routes on the day rather than trying to lock a rate at home.

Does opening a Thai bank account require me to file FBAR?

If your Thai bank account balance exceeds $10,000 at any point during the calendar year, yes, you must file FinCEN Report 114 (FBAR) with the US Treasury by April 15 (auto-extended to October 15). For a property purchase, your account will almost certainly exceed this threshold, making FBAR mandatory.

Does the transfer need to be one payment?

No, and on an off-plan purchase it cannot be. Each instalment produces its own record, and every one must show the same sender, in your own name, and the same stated purpose, the purchase of the unit. One tranche sent from a spouse's account or converted before sending is the gap that surfaces at registration or, worse, at the sale years later.

What is a FET certificate and do US buyers need one?

Yes. A Foreign Exchange Transaction (FET) certificate is issued by your Thai bank when foreign currency arrives from abroad and is converted to Thai Baht. The Thai Land Department requires FET certificates to register a condo freehold in a foreigner's name. You'll also need them when repatriating sale proceeds. Keep all originals, they cannot be replaced.
