Sending money between the US and abroad

Compare the amount that actually lands, not the fee, and relax: most transfers carry no reporting duty of their own.

The short version

The real cost of a transfer is the fee plus the exchange-rate margin, which is the gap between the rate you get and the mid-market rate.
US law requires remittance providers to show you the exchange rate, the fees and the amount the recipient will get before you pay. You can cancel within 30 minutes [1].
Moving your own money between your own accounts isn't taxed and needs no special form. The FBAR is about the foreign accounts, not the transfers [2].
Carrying more than $10,000 in cash across the US border needs FinCEN Form 105 [3]. Banks file a Currency Transaction Report for cash over $10,000 in a day [4].
Large gifts from foreign people can trigger Form 3520: over $100,000 a year from a foreign individual [5].

The options compared

The apps you used to split dinner checks back home won't carry over. Zelle only works when both the sender and the recipient bank in the US [7], and Venmo won't let you sign in at all from outside the country; its own help page points you to PayPal instead [8]. So you'll need one of these:

Method	Typical speed	How you pay	Where the cost hides	Good for
US bank international wire (SWIFT)	1–5 business days	Outgoing wire fee, often a receiving fee, sometimes intermediary bank fees	The bank's exchange rate, if the bank converts	Large, one-off amounts such as a home down payment
Wire in US dollars, converted by the foreign bank	1–5 business days	Same fees as above	The foreign bank's exchange rate	When the receiving bank's rate is better
Online money transfer service	Minutes to 2 days	A fee shown upfront	The margin on the exchange rate	Regular transfers like rent or a salary
Multi-currency account	Instant between your own balances	Conversion fee or margin	Small, but check limits and account fees	Holding dollars and local currency side by side
Brokerage foreign exchange	1–3 days	Commission or spread	Small for large amounts, but setup takes time	Large amounts, if you already have the account
Debit card at a foreign ATM	Instant	ATM fee, foreign transaction fee	The rate your bank or the ATM picks	Cash for the first weeks

Well-known transfer services include Wise, Remitly, Western Union and the transfer features of PayPal and Revolut, among others. Rates and fees change often and differ by currency pair and amount, so we don't rank them. Get two or three quotes for your actual amount on the day you send.

How to find the real cost

Look up the mid-market rate. That's the midpoint between buy and sell prices on the currency markets, the rate you see on financial news sites.
Get the "recipient gets" figure from each provider for the exact amount. US-regulated remittance providers must show it to you before you pay [1].
Divide the amount received by the dollars sent. Compare that to the mid-market rate.
Add the fees. The percentage gap plus the fee is your true cost.
Be wary of "no fee" offers. A transfer with no fee and a lousy rate can cost more than one with a fee and a close-to-market rate. That's the fine print doing its job.
Ask about intermediary fees on wires. SWIFT wires can pass through correspondent banks that skim a fee on the way, so less arrives than you sent.

A difference of one or two percent doesn't sound like much. On a USD 50,000 house down payment it's USD 500 to USD 1,000, which is real money.

When to use dollars and when to convert

Getting a US paycheck or pension abroad? Compare converting on the US side, through a transfer service, and on the foreign side. One is usually the clear winner.
Paying for things stateside? Keep a US dollar balance so you don't convert twice.
Big purchase coming? Some providers and banks let you lock in a rate ahead of time. That trades a possibly better rate later for certainty now.

If your partner is Australian and also moves money back to Australia, our sister site ExpatCooee covers sending money home from abroad from their side.

Your rights under the US remittance rule

When you send money from the US to another country through a provider that does it in the normal course of business, federal rules give you protections [1]. The CFPB's rule covers transfers over $15. Providers that made 500 or fewer transfers in both the prior and current year are exempt.

Disclosures before and after you pay: the exchange rate, fees and taxes, fees charged by the provider's foreign agents, and the amount the recipient should get. Some figures may be marked as estimates [1].
Cancellation: free within 30 minutes of paying, unless the money has already been picked up or deposited [1].
Errors: you have 180 days from the promised availability date to report one. The provider generally has 90 days to investigate, and you can usually choose a refund or a resend [1][6].

These protections apply to transfers sent from the US. A transfer you send from your foreign bank back to the US is governed by that country's rules.

Scam heads-up: never send money to someone you only know online, to "release" a prize or inheritance, or to fix a "problem" with your bank or the IRS. The IRS does not ask for wire transfers or gift cards. A completed transfer is very hard to reverse.

Reporting rules on large transfers

Plenty of people assume the IRS gets a report every time money crosses the border. It's more specific than that.

Situation	What's reported, and by whom	Your action
Transfer between your own US and foreign accounts	No tax and no special transfer form	File the FBAR if your foreign accounts total over $10,000 at any time in the year [2]
Cash over $10,000 deposited or withdrawn at a US bank in one business day	The bank files a Currency Transaction Report (CTR); multiple cash transactions in a day are added up [4]	Nothing. Don't split deposits to avoid it; structuring is a crime.
Carrying over $10,000 in currency or monetary instruments into or out of the US	You report it	File FinCEN Form 105 with CBP [3]
Gift or bequest from a nonresident alien over $100,000 in a year	You report it	Form 3520 [5]
Gift from a foreign corporation or partnership over $20,116 (2025) or $20,573 (2026)	You report it	Form 3520 [5]
Gift you give over the annual exclusion	You report it	Form 709 (see our gifts guide)

A few clarifications:

There is no limit on how much money you can carry in or out of the US. You just have to report it above $10,000 [3].
A bank wire is not cash. CTRs cover currency transactions [4], so an ordinary wire doesn't trigger one. Banks do keep records of wires and can file suspicious activity reports on unusual patterns. That's nothing to lose sleep over for normal transfers.
Money from your parents back in the States isn't income to you. If they give more than the annual gift tax exclusion to one person in a year, that's their Form 709, not yours.
The foreign country has rules too. Some countries have currency controls or ask banks to document the source of large incoming amounts, especially for property purchases. Ask the receiving bank what it needs before you send.

A US expat tax preparer can check your situation if you're receiving large gifts or inheritances from abroad, where penalties for a missed Form 3520 can be steep.

Tips for regular transfers

Set up the recipient once and test with a small amount before sending a big one.
Check that names match exactly across both accounts. Mismatches are a common reason for held transfers.
Keep confirmations. For your tax return, you may need the dollar value of foreign-currency amounts, and the date of a transfer can matter for currency gains on things like a foreign mortgage.
Mind daily limits. Online banking often caps how much you can send per day. Raise the limit before a deadline, not the morning of.
