USD to TWD for business payments

The New Taiwan dollar at a glance

The New Taiwan dollar (NT dollar, code TWD) is issued by the Central Bank of the Republic of China (Taiwan), known as the CBC. The CBC describes its regime this way: after the Taipei Foreign Exchange Market was established in February 1979, a flexible exchange rate system was formally implemented, and since then the NT dollar exchange rate has been determined by the market. When the market is disrupted by seasonal or irregular factors, the Bank steps in.

For a buyer, this means the rate moves with supply and demand, so an invoice priced in NT dollars can cost more or less in US dollars between order and payment.

Taiwan's foreign exchange rules for business payments

Taiwan uses declarations and settlement limits rather than a ban. "Settlement" here means converting between NT dollars and a foreign currency. The rules, as published by Invest Taiwan, are:

• Declaration at NT$500,000. Any foreign exchange receipt, payment or transaction of NT$500,000 or more must be declared. The company makes the declaration through its bank.
• Supporting documents above US$1 million. A single remittance by a company above US$1 million needs supporting documents, such as the contract or an approval letter.
• Approval above US$50 million a year. A company, limited partnership or firm whose aggregate settlement exceeds US$50 million a year must apply to the CBC, through its bank, for settlement approval. For individuals and organizations the figure is US$5 million.

These rules apply to the Taiwanese party, not to a foreign buyer. They still shape your payment. A supplier that is paid in dollars and keeps them in a foreign currency deposit account makes no settlement, so its annual limit is untouched. A supplier paid in NT dollars, or one that converts your dollars on arrival, uses part of that limit. Only large groups come near US$50 million, but the declaration at NT$500,000 applies to ordinary orders.

Our guide to USD business accounts in Taiwan covers the same rules from the supplier's side, including Taiwan's Virtual Asset Service Act passed at the end of June 2026.

How a payment reaches a supplier in Taiwan

The CBC describes Taiwan's payment framework as four systems: the CBC Interbank Funds Transfer System (CIFS), the FISC Financial Information System, the TCH Check Clearing System and the Central Government Securities Settlement System. CIFS is the hub of the interbank funds transfer network and links to the other systems. The Financial Information Service Co., Ltd. (FISC) runs interbank clearing for transfers, bill and tax payments and card payments through the Financial Information System.

A payment from abroad arrives at the supplier's bank by SWIFT, the international network banks use to send cross-border payments. Once a provider has converted dollars inside Taiwan, an NT dollar payout moves between banks on these domestic systems.

What converting USD to TWD costs

A dollar to NT dollar conversion has three parts: the mid-market rate, the midpoint between buying and selling prices at that moment; the margin, the difference between that midpoint and the rate you receive; and the payment fee. Because the NT dollar floats, also allow for movement between the invoice date and the payment date if the invoice is in TWD. Ask any provider for the NT dollar amount the supplier will receive, then compare that figure with the mid-market rate to see the real margin.

If you pay dollars instead, the conversion cost moves to the supplier, who converts at its bank's rate when it chooses, or keeps the dollars to pay its own suppliers.

Helm is a financial technology company, not a bank. Its US dollar account services are provided by Bridge Building, Inc. (NMLS ID 2450917), a licensed money transmitter, with customer funds held at Lead Bank. A Helm account holds dollars in your company's own name and sends international payments to suppliers by SWIFT, or by local rails in the supplier's currency where available, with the rate, fee and expected arrival shown before you send.

Helm agrees pricing with each business in writing before the account opens, and shows the rate, the fee and the expected arrival before you confirm each payment. See how Helm pricing works.

Pay a Taiwanese supplier in USD or TWD?

A foreign currency deposit account is the account most Taiwanese exporters already use, and the settlement rules give suppliers a reason to prefer dollars: dollars kept as dollars are not declared as settlement and do not count toward the annual limit.

• Pay USD when the invoice is in dollars and the supplier gives a foreign currency deposit account.
• Pay TWD for local costs, such as testing, warehousing or a local agent, or when a small supplier invoices only in NT dollars. Ask for the NT dollar account and expect the supplier's bank to apply its declaration rules.
• Do not send dollars to an NT dollar account. The supplier's bank converts on arrival at its own rate, and the conversion counts as the supplier's settlement.
