Sending money out of Korea

Why there are limits at all

Korea operates foreign exchange controls under the Foreign Exchange Transactions Act. They are not aimed at you — they exist for capital-flow management and anti-money-laundering purposes — but they shape every transfer you make.

The practical structure: you may send a certain amount per year without documenting where it came from. Beyond that, you must evidence the source. Once you do, the constraint largely disappears.

The document that changes everything

The key is proving that the money is legitimately earned Korean income. Any of these usually works:

• Income tax withholding receipt (원천징수영수증) — issued after your year-end settlement. The most commonly accepted document.
• Certificate of income (소득금액증명원) — from Hometax or a tax office.
• Certificate of tax payment (납세증명서).
• Employment certificate plus payslips.

Take one to your bank and register your remittance purpose once. After that, transfers up to your evidenced income go through routinely, and subsequent transfers become a five-minute app operation rather than a branch visit.

This is the single most useful thing in this guide, and almost nobody is told it. People send small amounts repeatedly for years, paying fees each time, because they hit a limit once and assumed it was fixed.

Bank versus transfer operator

The rule of thumb: transfer operators for regular smaller amounts, a bank for large one-off sums such as your final settlement when leaving.

Compare the total cost, not the fee

The headline fee is usually the smaller cost. The exchange-rate margin — the gap between the rate you get and the interbank mid-market rate — is where most of the charge sits, and it is invisible unless you look for it.

To compare properly:

1. Find the mid-market rate for KRW to your currency.
2. Ask each provider what you would actually receive for a specific amount, all in.
3. Compare those two received figures. Ignore everything else.

On ₩5 million, a 1% rate difference is ₩50,000 — several times a typical transfer fee. Providers that advertise "zero fees" are frequently the most expensive once the margin is counted.

Practical points

Get the recipient details exactly right

SWIFT/BIC code, IBAN or account number, and the recipient's name exactly as their bank holds it. A single wrong character can cost weeks and a recall fee. For a first transfer to a new recipient, send a small test amount.

Register the purpose once

Banks ask why you are sending money — family support, savings, tuition, loan repayment. Register it once with supporting evidence and subsequent transfers of the same type are far quicker.

Rates move

The won is a volatile currency. If you send regularly and are not in a hurry, watching the rate over a few weeks is worth real money. Most transfer apps let you set a rate alert.

Keep records

Retain transfer confirmations. You may need them for your own country's tax authority, and for evidencing the source of funds at the receiving end.

Receiving money into Korea

Generally simpler than sending out, but not unregulated. Large incoming transfers are reported, and your bank may ask about the source — particularly for amounts that do not match your known income.

One case where this matters a great deal: money brought in as investment capital for a D-8 visa must be notified as foreign investment before it arrives, through a designated foreign exchange bank or KOTRA. Funds that arrive first and are documented afterwards may not qualify, and unwinding that is difficult.

Tax

Sending your own already-taxed Korean income abroad does not create a new Korean tax liability. The transfer is not itself a taxable event.

What may create a liability is on the receiving end — some countries tax remittances, or treat them as income, or have gift tax rules that catch transfers to family members. Check the rules where the money is going, not only where it is coming from.

If you are a Korean tax resident with income arising outside Korea, that is a separate and more complicated question, and one worth taking to a licensed tax accountant (세무사).

When you leave Korea

This is the transfer that matters most, and the sequence is important:

1. Complete your early year-end settlement and get the withholding receipt.
2. Claim your pension lump sum and wait for it to land.
3. Recover your housing deposit.
4. Take the withholding receipt to the bank and transfer everything out in one go.
5. Confirm it has arrived.
6. Only then close the account.

Closing the bank account before the pension refund and deposit have landed is the classic mistake, and it turns a simple transfer into months of correspondence from another country. See the leaving Korea checklist.
