What is the cheapest way to send money out of Korea?

Specialist transfer services almost always beat bank wires on total cost, because banks charge a sending fee, an intermediary fee, and an exchange-rate margin. Compare the amount that lands, not the advertised fee.

Do I need to prove where the money came from?

For larger amounts, yes. Korean banks apply foreign-exchange rules that require documentation of the source of funds — commonly an employment contract, payslips, and a tax certificate. Keep these from the start.

Is there a limit on how much I can send abroad?

There are reporting thresholds rather than a single flat cap. Below the threshold the process is simple; above it, additional documentation and sometimes advance declaration are required. Thresholds change, so confirm with your bank.

Can I send money from Korea using a mobile app?

Yes. Licensed remittance apps operate in Korea and are generally cheaper and faster than bank wires, though they require identity verification and a Korean bank account to fund the transfer.

Sending Money Out of Korea: What It Costs

Sending money out of Korea is not difficult, but it is documented — considerably more so than in most countries. Korea maintains foreign-exchange rules that require banks to establish where money came from before it leaves, and arriving at a counter without the right papers is the most common way a transfer fails.

Here is what each route costs, and what you need before you start.

The three routes

Bank wire (SWIFT). Your Korean bank sends to your overseas bank. Reliable, universally accepted, and the most expensive by a wide margin. Costs stack in three places: the sending fee, intermediary bank fees deducted in transit, and — the big one — the exchange-rate margin, which is rarely presented as a fee at all.

Specialist transfer services. Licensed remittance providers operating in Korea. Substantially cheaper, usually faster, and increasingly the default for regular transfers. They require identity verification and a Korean bank account to fund the transfer.

Your bank's own app. Most Korean banks now offer in-app overseas transfers at better rates than the branch counter. Worth checking before assuming a third party is cheaper — for small amounts the difference sometimes narrows.

Comparing them honestly

The advertised fee is the wrong number to compare. What matters is how much arrives.

Route	Sending fee	Exchange margin	Typical speed
Bank wire at a branch	Highest	Widest	1–5 business days
Bank mobile app	Moderate	Moderate	1–3 business days
Specialist service	Lowest	Narrowest	Minutes to 2 days

To compare properly: take the amount you want to send, run it through each provider, and note the figure the recipient receives. That single number contains every fee and every margin. Providers that look cheap on fees and expensive on rate are common, and the comparison only surfaces it this way.

The documents

This is the part that catches people out. For anything beyond small routine amounts, expect to show:

Alien Registration Card — the foundation for everything
Proof of income source — employment contract, recent payslips
Tax documentation — an income tax withholding certificate is commonly requested
A completed foreign exchange declaration — the bank provides the form

The underlying logic is anti-money-laundering compliance: the bank must be able to demonstrate that outgoing funds are legitimately earned. It is not personal, and it is not negotiable.

Keep these documents from the day you start working. Assembling twelve months of payslips retroactively, from an employer you may have left, is far harder than saving them as they arrive.

The Bank of Korea publishes the foreign-exchange framework, though it is written for institutions rather than individuals; your own bank's foreign-exchange desk is the practical source.

Thresholds and reporting

Korea uses reporting thresholds rather than a single hard cap. Below a set annual amount, transfers are routine. Above it, the bank requires fuller documentation and, in some categories, advance declaration.

The thresholds change periodically, so treat any figure you read online — including this page — as needing confirmation with your bank before you plan around it. What does not change is the principle: larger and less regular transfers attract more scrutiny than smaller and steadier ones.

One practical consequence: sending a fixed amount monthly is administratively easier than sending a year's savings in one transaction, even where the annual total is identical.

Common mistakes

Comparing fees instead of the landed amount. The exchange margin is usually larger than every stated fee combined.

Leaving documents until you need them. Payslips and tax certificates are easy to collect monthly and painful to reconstruct.

Transferring on a Friday afternoon. Anything after the bank's foreign-exchange cutoff sits until the next business day, and a weekend adds two more.

Name mismatches. The recipient name must match the destination account exactly. A missing middle name is enough to have a transfer returned — after fees.

Assuming the branch and the app charge the same. They frequently do not, and the app is usually better.

Which to use

Regular monthly amounts home: a specialist service. The saving compounds.
A large one-off, such as a deposit refund: compare a specialist against your bank, and expect full documentation either way.
Urgent and small: a specialist app, which typically settles fastest.
To an account or country the specialists do not serve: a bank wire, accepting the cost.

Whichever route you pick, all of them are gated behind having a Korean bank account in the first place — see opening one as a foreigner. And if you are still working out what you will have left to send, the Seoul cost-of-living breakdown covers the monthly side.
