Transfer Your Housing Deposit Abroad Before Leaving Korea

You are leaving Korea, your landlord is about to return a deposit worth tens of millions of won, and your flight is booked. Sending that money abroad is not the same as sending ₩300,000 through a remittance app, and the order in which you do things matters more than the exchange rate. This guide explains what a designated foreign exchange bank is, which documents banks ask for, and how to sequence the transfer so it clears while your account is still a fully functioning resident account.

Why moving a large sum out of Korea is different from a routine remittance

Small remittance apps are built for amounts that sit below the point where Korean banks have to ask questions. Once you cross that point, the transaction stops being a consumer product and becomes a documented foreign exchange transaction handled by a bank branch.

The threshold is low. For remittances abroad above US$5,000 per transaction, the sender must in principle submit documentary evidence proving the purpose and the amount of the transfer (Korea Federation of Banks — 외환길잡이 (Korean-language source)). A returned monthly rent (wolse, 월세) deposit can already exceed that; a jeonse (전세) deposit almost always does.

There is a second reason the process changes. Korea's Foreign Exchange Transactions Act treats residents and non-residents differently: a resident is an individual with an address or residence in Korea, and a non-resident is one whose address or residence is abroad, and that classification decides which reporting obligations attach to a transfer (조세금융신문 (Korean-language source)). This explainer was not dated at the time of research, so confirm the current wording of the definition with your bank before relying on it. Your status is not a formality — it changes what your bank is allowed to let you do online.

The ARC surrender trap: how your account can stop working overnight

The Alien Registration Card (ARC; oegugin deungnokjeung, 외국인등록증) is handed in when you leave Korea permanently, and losing it is what most departing foreigners worry about last, after the deposit, the furniture and the flight. In practice it should be the last item on the list for a different reason: your banking flexibility depends on still being clearly a resident.

None of the official sources reviewed for this article state the exact legal moment at which a bank account's status flips from resident to non-resident — whether that is the physical surrender of the ARC at the airport, the departure stamp, or visa expiry. Because that trigger point is not published in plain terms, treat it as a risk to design around rather than a rule to time precisely, and confirm your own case with your account-holding bank and with Korea Immigration Service (HiKorea).

What is documented is what happens on the other side of the line. Foreign residents writing on Korean-language expat and finance forums consistently report that once an account holder is flagged as a non-resident, maintaining and transacting on a Korean bank account becomes much more restricted, which is why they advise arranging transfers while still unambiguously resident (해외 거주자를 위한 한국 은행 계좌 유지 방법 (Korean-language source)). Separately, some Korean banks cap internet and mobile banking transfers and ATM withdrawals at around ₩1,000,000 per day once an account is flagged as a limited financial transaction account (Seoulstart (Korean-language source)). A cap at that level makes a deposit-sized transfer impossible without a branch visit — and you cannot visit a branch from another continent.

The working rule for the rest of this article: money out first, ARC in last.

What a designated foreign exchange bank means and why you need one

A designated foreign exchange bank (georae oegukhwan eunhaeng jijeong, 거래외국환은행 지정) is a single bank you register with to handle a specific category of overseas transaction — general and gift remittances, study-abroad transfers, relocation of domestic assets. Once you designate it, that bank must be used for those transactions and it handles the post-transaction reporting (as of 2026; Korea Federation of Banks — 외환길잡이 (Korean-language source)).

Designation matters for two reasons. First, for non-residents and foreign residents, the ability to remit up to the "other payment" annual allowance without submitting proof of the source of funds is only available after a foreign exchange bank has been designated (Korea Federation of Banks — 외환길잡이 (Korean-language source)).

Second, the initial designation cannot be done online. For remittance of domestic assets by a non-resident, the first designation must be made in person at a physical branch; only afterwards can transfers be made through internet banking, and only to a receiving account abroad that is pre-registered and held in your own name (Woori Bank (Korean-language source)).

Read that last sentence twice. It means the one step that unlocks everything else requires your physical presence in Korea, with your passport and ARC in hand.

English-language service at branch level was not confirmed for KB Kookmin, Shinhan, Woori or Hana in the research for this article. Call your bank's customer line before you go and ask specifically for a branch that handles foreign exchange (외국환) transactions for foreign customers.

Documents your bank will ask for

Exact lists differ by bank and by whether you are still classified as a resident, so confirm with your own branch before you travel across the city. The items below are the ones that appear in official guidance or that follow directly from it.

Whether the withholding tax receipt is strictly mandatory for remitting severance pay, or whether an employer's transfer record can substitute, was not confirmed on the National Tax Service page reviewed. Banks may differ — ask your branch, and ask your employer for the receipt anyway, since it is a document they are obliged to issue.

Remittance limits and reporting thresholds

The figures below come from Korea Federation of Banks, Citibank Korea and Woori Bank guidance pages that were undated when accessed. Treat "as of 2026" as an approximation rather than a confirmed regulation-update date, and confirm the current figures with your bank before you rely on them.

Two points follow from this table. Reporting is not the same as prohibition: for a non-resident taking domestic property out of Korea, Woori Bank's guidance describes no fixed monetary ceiling per transaction, only automatic reporting above US$10,000 with a tax office certificate for the source of funds. And a jeonse deposit will typically blow past every evidence-free allowance in the table, so plan on assembling documents rather than on finding a shortcut.

This is also where consumer remittance apps stop being an option. They are not set up to review a lease contract, a tax office certificate and a severance withholding receipt, and the transaction sizes involved sit outside their normal range.

Your departure timeline: 4 weeks, 2 weeks and 2 days before you leave

The sequence below is strictly ordered. The single most expensive mistake is putting the ARC surrender before the confirmed arrival of funds abroad, because reversing those two steps is what leaves you trying to run a branch-only process from another country.

Standard processing times for large branch-initiated wires, and whether same-day handling exists above ₩50,000,000, were not confirmed by any source used here. Ask the branch for their expected timing when you initiate the transfer, and build in spare days rather than trusting a single business-day estimate.

Common problems foreigners run into — and how to avoid them

The landlord refunds the deposit on move-out day. What goes wrong: the money lands in your account 24 to 48 hours before your flight. What it costs you: the first designation of a foreign exchange bank has to be made in person at a branch, so a same-week refund can leave no working day in which to do it (Woori Bank (Korean-language source)). How to avoid it: complete the branch designation weeks before the refund, so the only thing left on the day the money arrives is the transfer itself.

The Romanized name does not match. What goes wrong: the spelling on the Korean bank account differs from the spelling on the passport attached to the receiving account abroad. What it costs you: some foreigners report on Korean-language finance forums that banks rejected large remittances for exactly this reason, with the delay landing in the last days before departure (마일모아 게시판 (Korean-language source)). How to avoid it: compare the Korean account name, the passport and the overseas account name character by character before the branch visit, and ask the bank in advance what it will do about a mismatch.

The account is already flagged. What goes wrong: an earlier visa expiry or status change left the account restricted before your current departure. What it costs you: on a limited financial transaction account, internet and mobile transfers and ATM withdrawals can be capped at around ₩1,000,000 per day (Seoulstart (Korean-language source)), and forum reports describe how much harder ordinary transactions become once a non-resident flag is attached (해외 거주자를 위한 한국 은행 계좌 유지 방법 (Korean-language source)). How to avoid it: ask the branch to confirm your current account status and daily limits at the start of the process, not the end.

The wrong branch, or no OTP. What goes wrong: you queue at a general teller who does not handle foreign exchange, or you leave Korea without an OTP device and without overseas use of internet banking enabled. What it costs you: a wasted trip during the narrow window you have, or being locked out of online banking once abroad. How to avoid it: relocation guidance for foreign account holders stresses visiting the specific branch where your foreign exchange designation sits and enabling overseas internet banking and OTP before leaving (IMMIKOREA Relocation (Korean-language source)).

The exact legal trigger that converts a resident account into a non-resident account was not published in any official English- or Korean-language page reviewed for this article, so no step here is timed to that moment — confirm your own case with your bank and with Korea Immigration Service.

Key takeaways

• The first designation of a foreign exchange bank must be made in person at a branch, which makes it the one step you cannot recover from once you have left Korea.
• Above US$5,000 per transaction you generally need documentary evidence of purpose and amount, and a returned housing deposit will need a tax office certificate for the source of funds.
• Move the money first and surrender the ARC last, with buffer days in between; the reverse order is what leaves people stranded abroad with a restricted account.
