Sending money abroad from Korea: limits, documents and the cheapest ways

This guide is for expats, foreign workers and investors living in South Korea who want to send money overseas. The short answer: you can transfer up to USD 50,000 a year without paperwork if you are a foreign resident, more if you provide proof of income, and costs vary sharply depending on the channel you use.

How it works

Every overseas transfer from a Korean bank account or licensed remittance service is governed by the Foreign Exchange Transactions Act (외국환거래법, the main law regulating cross-border money flows). The Act sets two controls: a documentation threshold and an annual ceiling. Below the threshold you transfer freely. Above it, you show documents. Banks and licensed online remittance services must report certain transfers to the Bank of Korea (BOK) and, at higher amounts, to the National Tax Service (NTS).

Since January 2026 the government has run the ORIS (Overseas Remittance Integrated System), a real-time database operated by the Bank of Korea that aggregates every transfer you make across all banks and remittance apps in the same calendar year. Institutions check your running total against ORIS before processing each transfer. Foreign nationals are identified in ORIS by passport number, so passport verification is now required when registering with any remittance service.

Why Korea does it this way

Korea maintained strict capital controls for decades after the 1997–98 Asian financial crisis (a severe regional currency and debt crisis) to protect foreign-exchange reserves and prevent sudden capital flight. The Foreign Exchange Transactions Act, enacted in 1999, formalised a tiered system: small transfers required no paperwork, large ones required a designated single bank and documentary proof. That bank-designation rule — which forced you to route all transfers through one pre-chosen institution — was abolished on 1 January 2026 as part of a broad liberalisation, the first such change since 1999.

The liberalisation also raised the no-document annual ceiling and introduced ORIS so the government could maintain oversight without the old single-bank bottleneck.

The numbers that matter

What it means for you

Understanding bank fees vs. online remittance fees

Every channel quotes you two costs. The first is the flat transfer fee — a fixed amount deducted before the money moves. The second, and usually larger, cost is the exchange-rate spread: the gap between the mid-market rate (the rate you see on any financial news site) and the rate the provider actually applies to your transfer. A spread of 2 % on a KRW 5,000,000 transfer costs roughly KRW 100,000 extra. Traditional bank wires tend to carry both a higher flat fee and a wider spread. Licensed online remittance services (fintech apps) typically apply a narrower spread, sometimes at or very close to the mid-market rate, with a small flat fee. Always calculate the total landed amount your recipient receives, not just the advertised fee.

How the won–dollar rate affects what arrives

The Korean won (KRW) has traded above KRW 1,400 per US dollar since late 2024 and averaged around KRW 1,486 per dollar in the first half of 2026 (Federal Reserve Bank of St. Louis, FRED series AEXKOUS). A weaker won means your KRW buys fewer dollars. If you are sending a fixed KRW amount, a 5 % depreciation in the won delivers roughly 5 % less to a USD-denominated account. Conversely, if your recipient needs a fixed USD amount, you will need to send more KRW. Monitor the mid-market rate at the Bank of Korea’s exchange-rate portal (bok.or.kr) or a neutral financial data site before transferring large sums.

Step-by-step checklist for foreign workers and residents

1. Register with a licensed channel and verify your passport. Your passport number is your ORIS identifier. Banks and remittance apps both require passport verification for foreign nationals. Bring your passport and Alien Registration Card (외국인등록증, the official ID card issued by the Immigration Service to foreign residents staying longer than 90 days) to the bank counter, or complete identity verification through the remittance app’s document-upload flow.
2. Know your annual headroom. Log into your bank’s internet banking or call the remittance desk to ask your running ORIS total. Your no-document annual ceiling as a foreign resident is USD 50,000. Once you approach that ceiling, you will need documents for any further transfers in that calendar year.
3. Gather proof-of-income documents before you exceed the ceiling. Acceptable documents typically include: a 근로소득 원천징수영수증 (Certificate of Wage and Salary Income Tax Withholding, issued by your employer or obtainable from Hometax at hometax.go.kr), a 소득금액증명원 (Certificate of Income Amount, obtainable from any tax office or Hometax), and/or recent pay stubs showing salary deposits into your Korean account. Your employer’s HR department can help obtain the withholding certificate.
4. For transfers above the no-document ceiling, go to a bank counter. Bring your passport, ARC, and income certificate. The bank’s foreign-exchange desk processes the transaction and files the required regulatory report. The transfer is not prohibited — it simply requires the paperwork.
5. Be aware of the NTS reporting trigger. A single transfer over USD 10,000, or cumulative annual transfers over USD 100,000, are reported to the National Tax Service. Reporting is not a tax assessment — it is an information flag. However, if the purpose of the transfer could be classified as a gift (e.g. sending money to a family member abroad with no expectation of repayment), consult a tax professional about gift-tax exposure before sending. Check current rules at nts.go.kr.
6. Compare total cost before each transfer. Get the mid-market KRW/USD rate from bok.or.kr or a neutral data site. Then ask your chosen channel: what rate will you apply, and what is the flat fee? Calculate the recipient’s landed amount. A slightly higher flat fee can be cheaper overall than a wider spread on a large transfer.

FAQ

Do I still need to designate a single remittance bank?

No. The requirement to nominate one designated overseas remittance bank was abolished on 1 January 2026. You can now split transfers across multiple banks and licensed online remittance services within the same calendar year. All transfers are aggregated automatically in ORIS, so your annual no-document ceiling applies across all channels combined, not per institution.

Will my remittance be taxed in Korea?

Sending money abroad is not itself a taxable event. Tax questions arise from the source of the money and the relationship between sender and recipient. Salary transferred to your own overseas account is not taxable on remittance (income tax was already withheld in Korea). A transfer to another person that constitutes a gift may attract gift tax if either party is a Korean tax resident. Transfers over USD 10,000 per transaction — or over USD 100,000 cumulatively in a year — are reported to the NTS as a matter of course. If you are unsure whether your transfer has a tax dimension, check with the National Tax Service (nts.go.kr) or a licensed tax accountant (세무사).

What is the cheapest way to send money from Korea?

Cost depends on the amount and destination currency. As a general rule, licensed online remittance services (fintech apps registered with the Financial Supervisory Service) apply narrower exchange-rate spreads and lower flat fees than traditional bank wires for most common corridors. However, the cheapest option varies by provider and by the day’s liquidity in the currency pair. Always calculate the recipient’s landed amount — not the quoted fee — using the mid-market rate from bok.or.kr as your benchmark. For very large amounts (above USD 50,000), a bank’s foreign-exchange desk may offer a negotiated rate that narrows the gap.
