Opening a Korean Brokerage Account as a Foreign Resident

Opening a Korean brokerage account changed on 14 December 2023 when the Financial Services Commission abolished the Investment Registration Certificate (외국인투자자 등록제, IRC). Any foreign resident with an Alien Registration Card (외국인등록증, ARC) can now open a Korean brokerage account and access KOSPI, KOSDAQ, and overseas markets without pre-registering with the FSS. The reality on the ground is messier than the policy: most major brokerages still require a branch visit for foreign residents, the 본인인증 (identity verification) phone gate catches new arrivals off guard, and English-language trading interfaces remain thin. This guide covers everything specific to opening and using a Korean brokerage account as a foreign resident.

What the IRC abolition actually changed

Before 14 December 2023, every individual foreign investor had to obtain an IRC from the Financial Supervisory Service (금융감독원, FSS) before opening any Korean brokerage account. The process involved engaging a securities company as a standing proxy and could take weeks. Periodic position-reporting obligations applied to some investor categories.

After abolition, the FSS pre-registration step is gone entirely. ARC holders use their ARC number as the unique account identifier. Non-residents without ARC use their passport number. Account opening now runs on the same timeline as a domestic account: same-day or next-day at most providers.

One reporting obligation remains for large positions. The Capital Markets Act (자본시장법) requires any investor who acquires 5% or more of a listed company's outstanding shares to report to the FSC and KRX by the close of the second business day after crossing the threshold. In practice this threshold is unreachable for ordinary retail investors, but the rule applies equally to foreign nationals.

The FSC confirmed the account-opening surge in a follow-up press release: 1,432 new foreign accounts were opened in the first six months after abolition, against a previous monthly average of roughly 105 under the old IRC system.

For broader context on how this brokerage account fits alongside ISA, IRP, and pension savings accounts, see the personal finance accounts hub guide.

The 본인인증 (identity verification) gate

This is the practical barrier that most English guides fail to explain. Most Korean brokerage apps require 본인인증 before you can open an account or use the app. The standard method works as follows.

1. The app sends an SMS to your Korean phone number.
2. The telecom carrier (통신사) cross-checks that number against the real-name registration on file.
3. If the registered name on the phone matches the name on your ARC exactly, verification passes.

What you need: a Korean postpaid SIM (후불 요금제) registered under the exact name on your ARC. Major network operators (SKT, KT, LG U+) and most MVNO budget carriers (알뜰폰) on postpaid plans now support this verification path for ARC holders. The PASS app, run by the major Korean telecoms, is the primary verification vehicle in most fintech apps.

What does not work: airport or tourist prepaid SIMs, foreign SIMs, roaming eSIMs, or any SIM where the name on registration does not exactly match your ARC. Even minor variations in romanization or middle-name format cause failure.

A practical name-format trap: if your ARC name is "NGUYEN THI LAN" but your SIM carrier registered you differently due to spacing or hyphenation conventions, 본인인증 fails. Verify that your telecom registration name matches your ARC name character for character before attempting any digital account opening.

As of 2024, twenty financial institutions, including KB Kookmin Bank, Shinhan Bank, Woori Bank, Hana Bank, Toss Bank, and NH Bank, adopted a system that enables ARC-based identity verification for financial services via mobile or branch. The Korea Herald reported this covers banking services and some securities services, but not all securities account flows have adopted this pathway.

The reliable workaround: Branch opening bypasses digital 본인인증 entirely. Staff verify your identity with physical documents. This is why the branch route remains the most dependable path for new arrivals.

Prerequisites that apply to all providers

Before approaching any brokerage, have the following in place.

ARC: Every provider requires your ARC as primary identification. Passport-only accounts are possible at some providers for non-residents, but they open a more restricted account type with different tax treatment. Wait for your ARC before opening a brokerage account.

Korean bank account: You need a linked Korean bank account in the same name as your ARC for cash deposits and withdrawals. Open this first. The bank account name and ARC name must match exactly. The how to open a Korean bank account guide covers the process.

Korean postpaid phone number: Required for any digital onboarding and for ongoing app use. See the section above.

Provider-by-provider opening options

The table below reflects the confirmation status from each provider's primary sources, checked 2026-05-25. "VERIFY" means no primary source confirmed the online-opening capability for ARC holders at the time of research.

Do not assume online capability for any VERIFY-status provider. Call or check the provider's current account-opening page before visiting or applying.

Mirae Asset Securities (미래에셋증권)

Branch visit is required for foreign residents. The official foreign-resident account opening page specifies an in-person branch visit during business hours (8:00-16:00). The non-face-to-face (비대면) account opening app explicitly excludes foreign nationals. Bring your ARC and passport to the branch.

Note: several English-language guides published in 2024 and 2025 describe Mirae Asset as supporting online or app opening for foreign residents. Those accounts conflict with the official page and should be treated as outdated or inaccurate. Confirm directly with Mirae Asset (1544-3322) before assuming any online flow exists.

Note on May 2026 news: Mirae Asset launched an omnibus account service for non-resident overseas investors through international broker partnerships. This is for people living outside Korea who want to invest in Korean markets without opening a Korean account. It does not affect the branch-required process for foreign residents living in Korea.

Samsung Securities (삼성증권)

Branch visit is required. Samsung applies a 6-month residency rule that changes the document set.

• Under 6 months in Korea (calculated from entry date or ARC issue date): ARC, passport, and an employment certificate (재직증명서) are required.
• Over 6 months in Korea: ARC and passport only.

F-4, F-6, or other visa holders who are not employed and have been in Korea under 6 months should contact Samsung directly if the employment certificate requirement creates an issue. Samsung has an English-language account-opening portal with documented foreign-resident instructions, and a dedicated English-speaking desk for foreign investor services.

In May 2026, Samsung launched an integrated service with Interactive Brokers (IBKR) allowing overseas retail investors to buy Korean stocks through their IBKR accounts. This is for non-resident investors. Foreign residents in Korea still use the standard branch process.

Kiwoom Securities (키움증권)

Branch visit is required for all foreign nationals. The non-face-to-face smart account opening service is explicitly limited to Korean nationals aged 19 and over. Foreign nationals must visit a 영업부 (branch or sales office). Bring your ARC and passport. Kiwoom's Hero app (키움 영웅문S) is the primary trading platform: it is Korean-only but well-regarded by Korean retail traders for its features.

KB Securities (KB증권)

KB Securities has an English-language presence and the KB M-able app includes a non-face-to-face account-opening guide. Whether ARC holders can complete the process online could not be confirmed from a primary KB source. If you already bank with KB (KB국민은행), ask your branch whether the brokerage opening can be handled there. Contact KB Securities directly before making assumptions about the online flow.

NH Investment Securities (NH투자증권)

NH Investment Securities (the securities arm, separate from NH Nonghyup Bank) could not be confirmed for ARC-holder online opening from a primary source. NH Nonghyup Bank launched dedicated foreign-customer desks in 2025, and the securities arm may follow similar patterns. The retail trading app is Namuuh (나무), a Korean-only interface. Contact NH Investment Securities at 1544-0000 or nhsec.com to confirm current policy.

Toss Securities (토스증권)

Toss added English, Chinese, Vietnamese, Thai, and Russian to its app in November 2025, per Korea Times reporting. Whether this multilingual expansion covers the Toss Securities account-opening flow specifically could not be confirmed from a primary source. Toss and Toss Bank historically had high authentication failure rates for foreign users due to name-format mismatches; Toss has reportedly improved these rates, but the securities opening flow is not separately documented. Verify at corp.tossinvest.com before applying.

Hana Securities (하나증권) and Shinhan Investment (신한투자증권)

Opening channel and document requirements could not be confirmed from primary sources for either provider. Hana Bank and Shinhan Bank both have documented foreign-resident support at the banking level; whether this extends to the securities arm's ARC-holder account-opening process is unconfirmed. Contact each provider directly.

What you can trade

Once your brokerage account is open, you have access to the following markets.

KOSPI (코스피, Korea Composite Stock Price Index): Korea's main board, equivalent to the NYSE. Listed companies include Samsung Electronics (삼성전자, 005930), SK Hynix (SK하이닉스, 000660), LG Energy Solution (LG에너지솔루션, 373220), Hyundai Motor (현대자동차, 005380), and NAVER (035420). Regular session runs 09:00-15:20 KST, with call auctions (동시호가) at the 09:00 open and 15:20-15:30 close.

KOSDAQ (코스닥): Korea's secondary tech and SME market, equivalent to NASDAQ. Representative names include Celltrion Healthcare (068760), Ecopro BM (247540), HLB (028300), and JYP Entertainment (035900). Higher growth potential, higher volatility.

KONEX (코넥스): A startup and small-cap board for SMEs and venture companies. The FSC abolished the minimum deposit requirement (기본예탁금) of ₩30 million for retail investors in April 2022, confirmed in an FSC press release. KONEX is technically accessible to retail investors without any minimum deposit, but trading volume is very low and it is generally not relevant to most retail accounts.

Korean-listed ETFs: KODEX, TIGER, KBSTAR, ACE, and other domestic ETFs, including trackers of foreign indices. ETF tax treatment differs from direct stock: see the fees and taxes section below.

Korean REITs and ETNs: Accessible via a standard brokerage account. Derivatives and ELS require separate qualifications at most providers.

Settlement on all trades is T+2. Sell on Monday, your cash arrives in the brokerage account on Wednesday. You cannot withdraw cash until settlement completes.

Order types and trading mechanics

Order types: The two order types you need to know are 지정가 (limit order, executes only at your specified price or better) and 시장가 (market order, executes immediately at prevailing price). For less liquid Korean stocks, 지정가 is generally the safer choice: bid-ask spreads can be wide and a market order can execute meaningfully below your expected price.

Daily price limits: Individual Korean stocks have a ±30% daily price limit from the previous session's close. If a stock hits +30% (상한가, upper limit) or -30% (하한가, lower limit), trading is locked at that price until the next session. This mechanism is unique to Korean markets and does not exist on US or European exchanges.

Circuit breakers: The KOSPI has three circuit breaker levels triggered by index falls: at -8% (trading halted 20 minutes), -15% (halted again), and -20% (market closed for the day). KOSPI triggered the -8% circuit breaker in March 2026, per Seoul Economic Daily reporting.

Short selling: Short selling resumed for all investors, including retail, on 31 March 2025, confirmed in a Korea.net government press release. Requirements: shares must be borrowed before placing the short order, cash collateral of 105%, and a 90-day borrowing period (renewable up to 12 months). Short selling requires margin account approval at most brokerages and is not a starting activity.

Fees and taxes

Securities transaction tax (증권거래세)

Every time you sell a Korean stock, a securities transaction tax is charged automatically by the brokerage. You never file separately for this; it is deducted from sale proceeds at the time of the transaction.

As of 1 January 2026 (as of 2026, verify at PwC Tax Summaries Korea):

• KOSPI: 0.20% of sale value. Breakdown: 0.05% base securities transaction tax + 0.15% Special Rural Development Tax (농어촌특별세).
• KOSDAQ: 0.20% of sale value. Full 0.20% as base STT; no separate rural tax.
• KONEX: 0.10% of sale value.

Context: The rate was 0.15% in 2025, reduced during the 금투세 transition period. It rose back to 0.20% from 1 January 2026 after the 금투세 was repealed and the compensating reduction was partially reversed. The 2026 increase was approved by the National Assembly in July 2025.

Capital gains tax on Korean-listed stocks

For retail investors below the 대주주 (large shareholder, 대주주 기준) threshold, capital gains on KOSPI and KOSDAQ stocks are zero. The threshold: holding 1% or more of any single listed company, OR holding ₩5 billion or more of any single stock measured at the end of the prior tax year. The Ministry of Finance reaffirmed the ₩5B figure in September 2025, per Newsis reporting.

For the overwhelming majority of foreign retail investors, neither condition will apply. You pay no Korean capital gains tax on Korean stock gains.

금투세 is gone

The financial investment income tax (금융투자소득세, 금투세) was passed in 2020, scheduled for 2023, postponed to 2025, and then repealed by the National Assembly in December 2024, effective 1 January 2025. It never came into force. If you read Korean financial news from 2020-2024 about a coming capital gains tax on stocks above ₩50M per year, that tax does not exist under current law.

Dividend withholding tax

Dividends from Korean stocks are taxed at source by the brokerage before they reach your account. For residents (거주자): 15.4% total (14% national income tax + 1.4% local income tax). For non-residents (비거주자): the domestic rate is 20%, though bilateral tax treaties typically reduce this.

Key treaty rates on portfolio dividends (from PwC withholding tax data, as of 2026, verify against your specific treaty):

If you are a Korean resident (거주자), these treaty rates typically apply to non-residents, not to you. As a 거주자, you pay the same 15.4% as Korean nationals. Home-country foreign tax credit rules determine how much relief you get on the Korea-side withholding.

ETF taxation: one trap to know

Korean-listed ETFs that track domestic stocks (for example, KODEX 200) are taxed the same as individual stocks: capital gains at zero for retail investors below the 대주주 threshold.

Korean-listed ETFs that track foreign indices (for example, TIGER Nasdaq100 or KODEX S&P500) are taxed differently: both capital gains from selling the ETF and distributions are taxed as dividend income (배당소득) at 15.4%, per Samsung Asset Management's ETF tax guide. This surprises investors who are used to US ETFs, where gains are capital gains. For Korean-listed foreign-index ETFs, there is no capital gains treatment: the gain is classified as distribution income and taxed at 15.4% automatically.

Brokerage commissions

Typical online retail commission: approximately 0.015% per trade at most major brokerages (as of mid-2026, confirm with each provider's current fee schedule before opening). Some brokerages apply a minimum commission per trade of ₩1,000-2,000. Commission rates change frequently and promotions are common.

Bank linkage and the CMA

Your brokerage account requires a linked Korean bank account in the same name as your ARC for KRW cash in and out. Most providers allow the bank link to be established digitally once the brokerage account is open.

Many brokerages also offer a cash management account (종합자산관리계좌, CMA). This sweeps your idle brokerage cash into short-term money market instruments (repurchase agreements, money market funds) so uninvested cash earns daily interest rather than sitting idle. CMA interest is taxed as interest income (이자소득) at 15.4%. CMA funds are not covered by the Korea Deposit Insurance Corporation (예금자보호제도), which protects bank deposits up to ₩100M per institution.

Foreign residents face the same ARC and phone verification gates for CMA opening as for the brokerage account. Confirm at your specific provider whether CMA opening requires a branch visit for foreign residents.

App and trading interface in English

Most Korean brokerage apps are Korean-only at the trading screen level. Toss Securities is the current exception, having added English, Chinese, Vietnamese, Thai, and Russian to its app as of November 2025. Samsung Securities has an English-language investor portal at samsungpop.com but the mPOP trading app is Korean.

For Korean-only apps, the minimum vocabulary to place a buy or sell order is small. The table below covers the core terms.

Most brokerage apps follow a common layout across providers. Navigate to the search bar, find your stock by name or code, tap 매수 or 매도, choose 지정가 (limit) or 시장가 (market), enter quantity and price, confirm. Test the app in view-only mode before placing your first live order.

What foreign residents specifically run into

Opening before your ARC is issued. Without an ARC, you either cannot open a brokerage account at all or must go through the old non-resident standing-proxy process, which is the complicated pre-abolition setup. Wait for your ARC.

Phone verification failing for digital accounts. An ARC-registered Korean postpaid SIM is mandatory for digital onboarding. Arriving with a tourist SIM or any prepaid plan causes digital 본인인증 to fail. The branch is the alternative.

Samsung's 6-month rule. If you have been in Korea under 6 months and want to open at Samsung, bring an employment certificate (재직증명서) from your employer. Without it, the branch will not process the account. Confirm the requirement directly if you are not employed.

ISA and IRP availability. Your brokerage account is separate from tax-advantaged accounts like the ISA (개인종합자산관리계좌) and IRP (개인형퇴직연금). Those accounts require Korean tax resident status and, in the case of IRP, Korean employment income. The brokerage account has neither requirement. For a full breakdown of eligibility, see the personal finance accounts hub guide.

Dual tax residency. Your Korean brokerage reports gains and dividends to the National Tax Service (국세청, NTS). If you remain a tax resident in your home country, that same income may need to be reported there. Korean dividend withholding (15.4%) may be eligible as a foreign tax credit against your home-country tax liability, depending on your country's rules and the bilateral tax treaty. For the tax implications of selling foreign stocks through a Korean brokerage, see the income tax guide.

Leaving Korea with open positions. When you cancel your ARC, you become a 비거주자. Dividend withholding rises from 15.4% to 20% under domestic rules unless a treaty applies. No Korean capital gains tax applies on departure for retail investors below the 대주주 threshold. To liquidate: sell holdings, wait T+2 settlement, transfer to your Korean bank account, and remit abroad via SWIFT or a remittance service. Move cash out of Toss Bank or Kakao Bank before you leave, as these online banks typically restrict non-resident accounts.

FAQ

Can I open a Korean brokerage account online without going to a branch?

It depends on the provider. Mirae Asset, Samsung, and Kiwoom all require an in-person branch visit for foreign residents, confirmed from their own account-opening pages. KB, NH, Toss, Hana, and Shinhan carry unconfirmed status for ARC-holder online opening. Check each provider's current terms directly before assuming any online flow is available to you.

I read about 금투세 (capital gains tax on financial investments). Do I owe it now?

No. The National Assembly repealed the 금투세 in December 2024, effective from 1 January 2025. It never came into force. Any Korean financial news you read about 금투세 between 2020 and 2024 describes a tax that no longer exists under current law.

Do I pay capital gains tax on Samsung Electronics stock?

Not as a retail investor. Capital gains on Korean-listed stocks are zero for any investor who holds less than 1% of a listed company AND holds less than ₩5 billion of a single stock at prior tax year-end. The vast majority of foreign retail investors fall well below both thresholds.

I don't have a Korean phone number yet. Can I still open an account?

Yes, through a branch visit. Digital opening requires a Korean postpaid phone for 본인인증. Any branch that handles foreign residents verifies your identity with your ARC and passport in person, bypassing the phone step entirely. Once the account is open, you will need an ARC-registered postpaid number for ongoing app access.

Which brokerage is the most foreign-friendly?

Samsung Securities has an English account-opening portal and a documented English-speaking desk, making it the most documented option for English-speaking foreign residents. Toss Securities is the most multilingual, having added English and four other languages to its app in November 2025, though whether its securities opening flow works for ARC holders is unconfirmed. All three confirmed-branch-only providers (Mirae Asset, Samsung, Kiwoom) can open your account same-day if you arrive with the correct documents.

Will my dividends be taxed twice, once in Korea and once in my home country?

Possibly, but partial relief usually applies. Korea withholds 15.4% on dividends for resident investors. Your home country taxes the same dividend income. Most bilateral tax treaties include a foreign tax credit mechanism to prevent full double taxation. The exact relief depends on your specific treaty and home-country rules. Confirm with a tax adviser if Korean dividends are a meaningful part of your income.

What happens to my brokerage account when I leave Korea?

Nothing is forced. You can keep Korean stock holdings as a 비거주자. Your dividend withholding rate rises from 15.4% to 20% under domestic rules unless a treaty provides a lower rate. To liquidate: sell holdings, wait T+2 settlement, transfer cash to your Korean bank, remit abroad. Close online bank accounts (Toss Bank, Kakao Bank) before you leave, as these typically restrict non-resident access.
