Yes, you can send ACH internationally from a U.S. bank account using a transaction type called an International ACH Transaction, or IAT. It moves through the same Nacha-governed ACH system as a domestic payment, but with extra compliance data attached and a gateway that hands the payment off to the receiving country’s clearing network. Expect it to cost a few dollars, settle in roughly two to four business days, and deliver funds in the recipient’s local currency.
When International ACH Beats a Wire
Cost is the reason to choose IAT. A wire transfer typically runs $15 to $50 in origination fees alone, and the recipient’s bank plus any intermediaries can deduct their own lifting fees from the amount that arrives. An international ACH transfer usually costs less than $5 and doesn’t incur lifting fees, so the recipient receives the full converted amount.
The tradeoff is speed and currency flexibility. A wire can arrive the same day or next day and can be denominated in U.S. dollars. An IAT settles in about two to four business days and delivers only in the recipient’s local currency. For recurring vendor payments, payroll, or dividend distributions where timing isn’t urgent, IAT is the obvious pick. For time-sensitive or dollar-denominated payments, pay the wire premium.
What You Need Before You Send
Getting the details right matters more here than for a domestic ACH, because errors are harder to unwind once funds cross into a foreign clearing system.
Recipient and Bank Details
You need the recipient’s full legal name exactly as it appears on their bank account, plus their physical street address. A P.O. box or an abbreviated name can trigger a rejection during compliance screening. You also need the recipient’s account number in whatever format the destination country uses.
The receiving bank is identified by a Business Identifier Code, commonly called a SWIFT code or BIC. A standard BIC is eight characters: four for the bank, two for the country, two for the location. Some banks add a three-character branch identifier for eleven total. The recipient’s bank can supply the correct BIC.
For most of Europe, the Middle East, and parts of Central Asia and the Caribbean, you’ll also need an International Bank Account Number. An IBAN embeds the country code, bank identifier, and account number into a single standardized string. More than 60 countries require an IBAN for incoming international transfers, and a transfer to one of those countries without an IBAN will likely be rejected.
Extra Fields for Business Senders
When a business rather than an individual initiates an IAT, Nacha’s rules require additional identification in the batch header. The originator identification field must carry the company’s IRS Taxpayer Identification Number. Mandatory addenda records must include the originator’s name, street address, city, state, country, and postal code. Miss any of these and the batch fails validation before it leaves your bank.
Fees, Exchange Rates, and Required Disclosures
What your bank charges for an IAT varies by institution and destination, but it’s a small fraction of what a wire costs. The real cost often hides in the exchange rate. Your bank or the gateway operator converts your dollars to the recipient’s local currency at a rate that usually includes a markup over the interbank rate. That spread is effectively a fee even though it doesn’t appear as a line item, so it’s worth comparing the quoted rate against the current interbank rate.
Federal rules require your bank to disclose the full cost before you authorize. Under Regulation E’s remittance transfer rules, the pre-payment disclosure must show the transfer amount, all fees and taxes collected by the provider, the exchange rate, and the total the recipient will receive. If third-party fees apply on the receiving end, the disclosure has to say the recipient may get less than the stated amount. Read that disclosure carefully; it’s the clearest picture of the total cost you’ll get.
Timing, Tracking, and Returns
After you authorize, your bank packages the payment into an IAT file and sends it to a gateway operator, which translates the data into the receiving country’s format, converts the currency, and forwards it into the local clearing network. Most destinations settle in two to four business days, though the exact timing depends on the receiving country’s payment infrastructure.
Your bank should give you a transaction reference number. Keep it; you’ll need it to trace the payment or dispute an error. Online status updates may lag by a day because the gateway and foreign clearing system run on their own schedules.
If the transfer fails, it comes back with a return code. The IAT-specific ones you’re most likely to see include R80 for coding errors such as an invalid country or currency code, R82 for an unrecognizable foreign bank identifier, R83 when the foreign payment system can’t settle, and R84 when the gateway declines to process due to risk or system limitations. R85 flags a payment that was coded as domestic when it should have been an IAT, which is a compliance problem for the originating bank rather than something you fix on your end. Your bank should tell you which code came back and what needs to change before resubmitting.
Your Right to Cancel or Dispute
Federal law gives you a 30-minute window after authorizing an international transfer to cancel at no cost, as long as the recipient hasn’t already received the funds. To cancel, contact your bank with your name, address or phone number, and enough detail to identify the specific transfer. If the cancellation is valid, the bank has to refund the full amount, including all fees and taxes, within three business days.
After that window closes, you have up to 180 days from the disclosed availability date to report an error. Covered errors include the wrong amount arriving, funds sent to the wrong account, or the recipient not receiving the transfer at all. Your notice needs your name, contact information, which transfer you’re disputing, and what you think went wrong. The bank then has 90 days to investigate and must report its findings within three business days of finishing.
These protections come from Regulation E and apply to providers that handle more than 500 international transfers a year, which covers essentially every bank offering the service. If you’re using a smaller niche provider, ask whether Regulation E protections apply before you send.
Where You Can’t Send
Every IAT is screened against the Office of Foreign Assets Control’s Specially Designated Nationals and Blocked Persons List before it clears. If the recipient, their bank, or an intermediary is on the SDN list, the transfer will be frozen or rejected. This isn’t discretionary for your bank; penalties for letting a prohibited transaction through are severe.
Some countries are subject to comprehensive sanctions that block most financial transactions outright. As of 2026, comprehensively sanctioned jurisdictions include Cuba, Iran, North Korea, Russia, and the Crimea, Donetsk, and Luhansk regions of Ukraine. Sending an IAT to any of these requires a specific OFAC license, which is rarely granted for routine transfers, and your bank will reject the transaction in most cases. OFAC’s programs change with geopolitical conditions, so check the current list if you’re sending to a region with any political instability.
A Note on Foreign Account Reporting
Sending an international ACH doesn’t by itself create a tax filing obligation, but holding money in a foreign account can. If you have a financial interest in or signature authority over foreign accounts whose combined value exceeds $10,000 at any point during the year, you must file a Report of Foreign Bank and Financial Accounts on FinCEN Form 114. The FBAR is due April 15 following the calendar year, with an automatic extension to October 15 and no extension request required. It’s filed electronically through FinCEN’s BSA E-Filing System, separately from your tax return. Keep records for each reported account for at least five years from the FBAR’s due date. Penalties reach $10,000 per violation for non-willful failures and up to 50 percent of the account’s maximum balance for willful ones. If you’re using international ACH to fund or manage a foreign account, confirm whether the FBAR applies to your situation.
