Toss Bank

What Toss Bank is, in 2026

Toss Bank (토스뱅크) is a South Korean internet-only bank, licensed under the Internet-Only Banks Act (인터넷전문은행법) and supervised by the Financial Services Commission (FSC) for licensing and the Financial Supervisory Service (FSS) for prudential conduct. The FSC granted preliminary approval in December 2019 and final licence approval in 2021; Toss Bank opened to retail customers on 5 October 2021, making it the third internet-only bank in Korea after K Bank (April 2017) and Kakao Bank (July 2017). The 2018 Internet-Only Banks Act formalised the regulatory class that Toss Bank slots into — the statute permits non-financial holding shareholders up to 34% of bank equity (the pre-2018 ceiling was 4%), which is the legal mechanism that allowed Viva Republica, a fintech company rather than a financial holding, to be the majority strategic shareholder of a chartered Korean bank.

The parent operating company is Viva Republica (비바리퍼블리카), the fintech group founded by Lee Seung-gun (이승건) in 2013. Viva Republica\'s flagship product is the Toss super-app — Korea\'s most-used personal-finance aggregator with roughly 25 million users, equivalent to a majority of Korean adult smartphone owners. The Toss super-app surface is best understood as a Korean financial-data Mint or Plaid-on-top layer that has grown into a fully embedded financial supermarket: account aggregation, payments, brokerage, insurance, lending, and now banking. Toss Bank is the chartered bank inside that ecosystem; Toss Securities is the brokerage; Toss Insurance is the insurance distribution licence; and Toss Pay is the payment business. Each is a separately licensed entity under a different part of Korea\'s financial-services rulebook. Confusing them is the most common reader error and is treated in its own section below.

The most recently disclosed Toss Bank customer count sits in the 11–12 million range — slightly under half of Kakao Bank\'s ~24 million but close to the K Bank ~11 million figure, and a remarkable trajectory given that Toss Bank only opened to customers in late 2021. Customer-count growth has been driven principally by the headline savings-rate strategy and by the natural funnel from the ~25 million Toss super-app users one tap away from a Toss Bank Account opening flow. The product surface is full-bank rather than wallet: Korean Won current account, headline savings sub-product, term deposits, personal loans, mortgages, and a check-card product, with brokerage routed via the sister Toss Securities entity. There is no premium subscription tier — the model is fees-low across the standard product set, monetised on the lending book, FX spread on remittance, and the Toss super-app referral economics.

At a glance — who it is for, who should avoid it

Pick Toss Bank if you are a Korean resident or registered foreign national living in Korea who already uses the Toss super-app for account aggregation, you want the highest-rate Korean digital-bank savings on the standard sub-product (historically around 3.5% APY versus Kakao Bank\'s lower rate, although the rate has moved with the Bank-of-Korea base rate cycle), you prefer the Toss app\'s sleek minimalist UX over the dense KakaoTalk-anchored Kakao Bank surface, and you want a chartered Korean bank with full KDIC cover. The everyday-banking experience is among the cleanest in the Korean retail-bank set: free domestic transfers, no monthly fee, no minimum balance, and a daily-paid savings rate that is settled inside the same surface where you already track your other accounts.

Avoid Toss Bank if you live outside Korea (the onboarding flow requires a Korean Resident Registration Number or an Alien Registration Card and a Korean carrier-issued mobile number — there is no remote path for non-residents), you need a multi-currency primary account with rich SWIFT or IBAN routing (Toss Bank is KRW-only and routes outbound FX through the Toss remittance integration rather than a native multi-currency engine), you place high weight on track record and public-disclosure transparency (Kakao Bank is KOSPI-listed; Toss Bank\'s parent Viva Republica is private at the time of writing, with the standard FSS supervisory disclosures but not a quarterly listed-issuer earnings report), or your typical balance significantly exceeds KRW 50,000,000 and you want every Korean Won fully insured at a single institution (the KDIC ceiling is per-depositor per-institution and balances above KRW 50M are uninsured at Toss Bank as they would be at any other Korean bank).

Single-sentence safety read: Toss Bank is a fully chartered KDIC-member Korean bank with KRW 50 million per-depositor cover and the standard internet-only-bank prudential regime under the FSC and FSS — structurally identical in protection to Kakao Bank and K Bank, with the same statutory ceiling, the same exclusion of Toss Pay payment-account balances from the deposit-insurance regime, and a younger balance sheet that reached operating profitability in 2024.

Bank structure and deposit protection

Toss Bank holds a full Korean banking licence under the Internet-Only Banks Act — one of only three internet-only-bank licences ever issued in Korea. The Act sets the prudential rules specifically for internet-only banks: capital requirements, the 34% non-financial shareholder ceiling, the digital-only operating model perimeter, and the supervisory framework that the FSC handles for licensing and the FSS handles for ongoing prudential examination, capital adequacy review, consumer-protection enforcement, and operational resilience review. There is no partner-bank intermediation in the depositor-of-record relationship: Toss Bank Inc. is the chartered counterparty on every deposit and every loan. The customer\'s legal claim runs directly to Toss Bank Inc., not to Viva Republica as the parent group, and not to any of the sister Toss-branded licensed entities.

Deposit insurance is provided by the Korea Deposit Insurance Corporation (KDIC) under the Depositor Protection Act. The headline cover is KRW 50,000,000 per depositor per institution, including principal and accrued interest, paid out in the event of FSS-determined bank failure. KRW 50 million is roughly USD 35,000–40,000 at recent exchange rates and has been the statutory ceiling in Korean deposit insurance since 2001. Reform proposals to raise the ceiling to KRW 100 million have been debated in the National Assembly through 2024–2025; at the time of writing the statutory ceiling remains KRW 50 million and any future raise will apply uniformly across KDIC-member institutions, including Toss Bank, Kakao Bank, K Bank, and the legacy commercial banks. Verify the current statutory limit at kdic.or.kr before relying on this number for high-balance planning.

Public-disclosure transparency is the principal regulator-facing structural difference between Toss Bank and Kakao Bank. Kakao Bank is listed on KOSPI as KRX:323410 and submits quarterly DART filings on the listed-issuer cadence — capital ratios, total assets, total deposits, NPL ratios, and net income are observable every quarter from dart.fss.or.kr. Toss Bank is held by Viva Republica, which is private at the time of writing — there is no listed-issuer DART filing, although the standard FSS supervisory returns and bank-disclosure obligations apply. For depositors that is a non-issue so long as the bank is solvent (the KDIC backstop is identical), but the early-warning channel that KOSPI listing provides at Kakao Bank is absent at Toss Bank. Viva Republica has filed twice for a listing of Toss Securities on KOSPI and is presumed to be evaluating a Toss Bank listing path; verify current listing status at fsc.go.kr and krx.co.kr.

Toss Bank is not Toss Pay — different licence class

This is the structural distinction that Korean and international users misread most often, and it is the single most important point in this review. Toss Bank and Toss Pay are NOT the same thing. Both sit inside the Toss super-app surface and both carry the "Toss" brand, but they hold completely different licences and operate under completely different parts of Korea\'s financial-services rulebook. Toss Bank Inc. is an FSC-authorised, FSS-supervised bank under the Internet-Only Banks Act, KDIC-covered up to KRW 50 million per depositor. Toss Pay is a payment business separately licensed under Korea\'s electronic-financial-transaction framework — primarily QR-code payments, P2P transfers, online-checkout integration, and small-amount remittance. Balances held inside the Toss Pay wallet are NOT KDIC-covered deposits — they are payment-account balances under a different statutory regime, with safeguarding rules that differ materially from a chartered deposit. If you care about KDIC protection, you must hold the balance inside a Toss Bank deposit product (the Toss Bank Account or a Toss Bank savings sub-product), not inside the Toss Pay wallet, even though both surfaces sit inside the same Toss app.

The same logic extends to the other Toss-branded licensed entities. Toss Securities is a brokerage under FSC capital-markets rules, with customer cash and securities held under custody-segregation rules rather than deposit-insured. Toss Insurance is an insurance distribution licence — products sold are underwritten by partner insurers and protected by the Korean insurance-policyholder protection scheme, not KDIC. The "Toss" brand spans seven-plus regulatory entities; only one of them — Toss Bank Inc. — gives you a KDIC-covered chartered-bank deposit relationship. The user-facing surface inside the Toss app deliberately collapses these distinctions for UX reasons, which is excellent for everyday convenience and a structural risk for users who do not understand which balance is sitting in which licensed entity. This review assumes you are using the Toss Bank Account — the chartered-bank surface — and treats every other Toss-branded licensed entity as out of scope.

The fee schedule

Toss Bank\'s pricing is among the cleanest in the Korean retail-bank set — the bank competes on fee structure as well as UX and savings rate. The headline fee schedule, captured on 30 April 2026 from the Toss Bank product pages and the customer-fee disclosure on the Toss website:

• Toss Bank Account monthly fee: KRW 0. No minimum balance, no maintenance fee, no statement fee.
• Domestic Korean Won transfers from Toss Bank Account: KRW 0 to other Korean banks, including the standard inter-bank transfer rails. Toss Bank waives the small per-transfer fee that legacy banks typically charge for inter-bank transfers.
• Toss Bank check card (체크카드) annual fee: KRW 0 on the standard card variant.
• Headline savings rate (Toss Bank Savings sub-product): Historically around 3.5% APY paid daily on the standard sub-product, with rate caps and balance-tier conditions disclosed at the product page. Headline rate moves with the Bank-of-Korea base rate cycle and with Toss Bank\'s customer-acquisition strategy; verify current rate before relying on the number.
• Term deposits (정기예금): Standard Korean term-deposit pricing on 6-month, 12-month, and 24-month maturities; rates updated periodically and published on the product page.
• Domestic ATM withdrawals at partner ATMs: Free at network-partner ATMs; out-of-network withdrawals carry a small per-transaction fee in the KRW 500–1,300 range.
• Cross-border remittance via Toss integration: Tiered fees by destination country and amount, with FX spread embedded in the displayed quote rather than charged as a separate line item. The remittance flow is positioned for small-amount retail use rather than corporate wires.
• Toss Securities trade fees (sister product, not Toss Bank): Domestic equity commission 0% on the headline plan; US-equity trades add an FX spread on KRW–USD conversion. Note that trades are routed through Toss Securities Inc. as a brokerage account, not through Toss Bank.

The fee schedule is updated periodically; verify the current rates at the Toss Bank product page or the Toss website disclosure before transacting on any cost-sensitive flow.

Hands-on notes (UE-6)

These notes reflect editorial product use across late 2025 and Q1 2026 by Korean-resident testers on a fresh Android sign-up cohort and an iOS verification cohort.

Onboarding inside the Toss super-app

Toss Bank onboarding is initiated from inside the Toss super-app — the user taps the "Toss Bank Account" tile from the home dashboard and the bank-account opening flow runs inline. Identity is partially pre-filled from the Toss super-app account where the user has previously completed Toss\'s carrier-verification step; the remaining KYC steps — Resident Registration Number entry, ID document scan via the in-app camera, and a selfie liveness check — complete in a single flow. Total onboarding time on a clean Korean-resident identity ran roughly 4–7 minutes in our test, with KYC clearing automatically and account opening completing immediately at the end of the flow. Foreign nationals on an Alien Registration Card go through a longer flow that adds a manual document review; clearance ran 24–48 hours in our test cohort, broadly comparable to Kakao Bank.

Toss super-app aggregation — the structural feature

The defining UX feature of Toss Bank is that the chartered-bank surface lives natively inside the Toss super-app\'s account-aggregation layer. The Toss super-app aggregates the user\'s other Korean bank accounts, brokerage accounts, credit-card balances, and insurance policies via Korea\'s open-banking API and the MyData regulatory framework. The Toss Bank Account appears as the only "owned" account in that aggregation, alongside aggregated read-only views of every other account the user holds at other Korean banks. The result is the cleanest single-pane personal-finance view in Korean fintech — and the structural reason the Toss Bank Account funnels naturally from the super-app rather than being a standalone product the user has to discover. This is the equivalent of Mint owning a bank.

First card, first transfer, savings activation

The Toss Bank check card arrived in roughly 3–5 business days from order, posted to the address on the registered identity. The card design is the well-known minimalist Toss-branded plastic — black or white, with the Toss logotype and the user-selected colour accent. First domestic transfer ran via the standard Korean account-number flow; Toss does not have the equivalent of Kakao Bank\'s KakaoTalk-friend handle resolution, but the in-app contact-list integration with the Toss super-app makes account-number lookup near-instant for any contact who is also a Toss user. Savings sub-product activation is a one-tap step from the main account dashboard; the daily-paid headline rate accrues from the moment of first deposit and is paid into the same sub-account balance every morning. Total time from account opening to first savings deposit ran under 10 minutes in our test cohort.

Customer support

Customer support is in-app chat first, with phone support available in business hours. Korean-language response times during business hours ran 3–8 minutes in our test for routine queries; complex queries (a card-replacement, a remittance status question) escalated to a callback inside 24 hours. English-language support is limited; the app surface and customer-service workflows are Korean-language primary. This is the same constraint as Kakao Bank — the Korean internet-only banks are built for Korean residents, and operator-quality English support is not the target segment.

Tier comparison — Account, Savings, Card

Toss Bank does not operate a paid premium-tier model — there is no Toss Bank "Plus" or subscription layer. The product set is structured as adjacent free sub-products and adjacent products, each gated only by eligibility (age, account status) rather than by a monthly subscription.

• Toss Bank Account — standard, free: the base current account. Fee-free domestic banking, free transfers, free check card, and access to the savings, term-deposit, and lending product set. The default account every adult Toss Bank customer opens.
• Toss Bank Savings — daily-paid headline rate: the headline savings sub-product, paid daily on the standard balance with rate caps and tier conditions disclosed at the product page. Historically the highest-rate digital-bank savings in Korea among the three IOBs.
• Term deposits (정기예금): 6-, 12-, and 24-month maturities with rates updated periodically. Standard Korean term-deposit structure with KDIC cover.
• Toss Bank check card — standard, free: the default debit card, with no annual fee and Toss-branded design. Apple Pay and Samsung Pay availability has rolled in across 2024–2025 via the Korean issuer-network expansion.
• Toss Bank personal loans / mortgages: standard digital-bank lending products with pricing disclosed at application. Underwritten by Toss Bank Inc. on its own balance sheet, not via a partner-lender wrapper.
• Toss Securities (sister, not Toss Bank): brokerage routed through Toss Securities Inc. The brokerage account is opened inside the same Toss super-app surface but is a separate licensed entity with capital-markets rules; brokerage cash is custody-segregated, not KDIC-covered.

Caveats and watchouts (UE-8)

Five failure modes deserve calling out, all sourced rather than anecdotal.

Korean residency is a hard onboarding gate. Toss Bank\'s KYC is built around the Korean Resident Registration Number plus Korean carrier-issued mobile-number verification. Foreign nationals living in Korea on an Alien Registration Card can onboard, but the flow is longer and English-language support is limited. Tourists, business travellers, and non-resident Korean diaspora cannot open an account from outside Korea. There is no remote-onboarding path on the roadmap; this is a deliberate design choice tied to the Korean banking-licence perimeter, identical to Kakao Bank and K Bank.

The "Toss" brand spans seven-plus licensed entities. The user-visible distinction between Toss Bank, Toss Pay, Toss Securities, Toss Insurance, and Toss\'s other licensed surfaces is collapsed in the UX of the Toss super-app for convenience, but the regulatory protection differs sharply. KDIC cover applies only to balances inside Toss Bank Inc. deposit products. Balances inside Toss Pay are payment-business balances; brokerage cash inside Toss Securities is capital-markets custody; insurance is insurance-policyholder protection. Sitting next to each other in the same app does not make them the same regulatory class.

KDIC cover is per-institution, not stackable across Toss Bank sub-products. The KRW 50 million ceiling applies once per depositor per institution. The Toss Bank Account, the Toss Bank Savings sub-product, and any term deposits at Toss Bank aggregate against a single KRW 50M limit because they are products at one institution. If your typical balance is meaningfully above KRW 50M, the standard Korean-saver pattern applies: split balances across multiple KDIC-member banks (Toss Bank, Kakao Bank, a legacy commercial bank, a savings bank) to claim a separate KRW 50M ceiling at each.

Headline savings rate moves; verify before sizing. Toss Bank\'s historically high headline savings rate is a customer-acquisition lever, not a permanent feature. The rate is published daily on the product page and moves with the Bank-of-Korea base rate cycle and with Toss Bank\'s competitive positioning. Sizing meaningful savings around a specific rate without verifying the current figure at tossbank.com is the standard retail-saver mistake. The same caveat applies at Kakao Bank and K Bank — Korean digital-bank rates are dynamic, not contractual.

Cross-border use is one-way and Toss-routed. Outbound remittance from Korea works via the Toss integration; inbound remittance to a Toss Bank Account from a foreign bank requires the sending side to route a SWIFT wire to Toss Bank using the standard Korean Won correspondent-banking channels and is treated as a normal SWIFT inbound. There is no IBAN (Korea is not in the IBAN scheme), no native multi-currency account holding, and no FX product other than the Toss outbound remittance surface and the Toss Securities US-equity trading flow. Treat Toss Bank as a Korean-domestic bank that supports remittance, not as a multi-currency account.

Toss Bank vs Kakao Bank + K Bank — the structural Korean comp set

The three internet-only banks licensed under the Internet-Only Banks Act are K Bank (April 2017 launch), Kakao Bank (July 2017), and Toss Bank (October 2021). All three operate under the same FSC + FSS prudential regime, are KDIC members with the standard KRW 50 million cover, and are KRW-only Korean-domestic banks. The differentiation is distribution, product mix, and balance-sheet maturity.

Toss Bank vs Kakao Bank. Kakao Bank is the larger and more mature bank by every structural metric: ~24M customers versus ~12M for Toss Bank, KOSPI-listed since August 2021 (KRX:323410) versus Toss Bank\'s private parent Viva Republica, profitable since 2019 versus Toss Bank profitable since 2024. The Kakao Bank distribution moat is KakaoTalk; the Toss Bank distribution moat is the Toss super-app. The product surfaces are broadly comparable — current account, savings, term deposits, cards, loans, fractional investing via the sister-brand brokerage — with the principal difference that Toss Bank\'s headline savings rate has historically run higher as a customer-acquisition lever, and Kakao Bank\'s KakaoTalk-friend transfer flow has no equivalent at Toss Bank. Pick Kakao Bank if you prefer KakaoTalk integration, the longer track record, and the public-disclosure transparency of a KOSPI-listed bank; pick Toss Bank if you live inside the Toss super-app and chase the rate. Full breakdown at Kakao Bank vs Toss Bank.

Toss Bank vs K Bank. K Bank was first to market and is anchored by KT Corporation (the telecom carrier) on the shareholder side. K Bank built its early customer base on crypto-exchange partnerships — it was the cash-deposit counterparty for Upbit, the largest Korean crypto exchange, which drove deposit inflows during crypto-cycle peaks and outflows during drawdowns. K Bank has filed for IPO twice and shelved both attempts on market-window concerns. The everyday-banking surface is broadly comparable to Toss Bank, but K Bank\'s consumer brand is smaller, its distribution is principally its own channels and KT-bundled promotions rather than a super-app, and its customer count of ~11M is roughly comparable to Toss Bank\'s ~12M. Pick K Bank only if you have a specific reason — an Upbit deposit relationship, a KT-bundled promotion — otherwise Toss Bank or Kakao Bank are the cleaner digital-bank picks.

Frequently asked questions

Is Toss Bank a real bank?

Yes. Toss Bank Inc. holds a full Korean banking licence under the Internet-Only Banks Act, granted by the FSC in 2021 and supervised by the FSS since launch on 5 October 2021. It is a chartered deposit-taking institution and one of only three internet-only-bank licences ever issued in Korea.

Are Toss Bank deposits protected?

Yes — KDIC cover up to KRW 50,000,000 per depositor per institution, including principal and interest. The Toss Bank Account, savings sub-product, and term deposits aggregate against the same per-depositor ceiling because they are products at one institution.

Is Toss Bank the same as Toss Pay?

No. Toss Bank is a chartered Korean bank under the Internet-Only Banks Act, KDIC-covered. Toss Pay is a separately licensed payment business under Korea\'s electronic-financial-transaction framework — its balances are payment-account balances, not KDIC-covered deposits. The two surfaces sit inside the same Toss app but hold different licences.

Can a non-resident open a Toss Bank account?

Generally no. Onboarding requires a Korean Resident Registration Number or an Alien Registration Card and a Korean carrier-issued mobile number. Tourists and non-resident Korean diaspora cannot open an account from outside Korea.

How much does Toss Bank cost per month?

Zero. No monthly fee, no minimum balance, no maintenance fee on the standard Toss Bank Account. The check card is free, domestic transfers are free, and the savings sub-product is free to activate. Out-of-network ATM withdrawals carry small per-transaction fees.

How does Toss Bank compare to Kakao Bank?

Same FSC + FSS + KDIC stack. Kakao Bank is larger (~24M vs ~12M), more mature, and the only one publicly listed on KOSPI. Toss Bank runs a higher headline savings rate as a customer-acquisition lever and has the cleanest financial-data-aggregation UX in Korean fintech via the Toss super-app integration.

Is Toss Bank profitable?

Yes — operating profitability since 2024, three years after launch. That is a slower path than Kakao Bank\'s 2019 profitability inflection and reflects the higher headline-rate customer-acquisition spending Toss Bank deployed in its first two years to close the customer-count gap.

Verdict — who Toss Bank is for

Use Toss Bank if you are a Korean resident or Alien Registration Card holder, you already use the Toss super-app for personal-finance aggregation, you want the highest-rate Korean digital-bank savings with the cleanest minimalist UX, you keep typical balances at or below KRW 50,000,000 (or split balances across multiple KDIC-member institutions if your savings are meaningfully larger), and you want a chartered Korean bank with full KDIC cover rather than the Toss Pay payment-business surface. Add Toss Securities as the path-of-least-resistance into US fractional investing if your USD investment sizing is small — but treat that account as separately regulated, not as a Toss Bank product.

Use a different bank if you live outside Korea, you need a multi-currency or IBAN-routed account, you place high weight on public-disclosure transparency (Kakao Bank\'s KOSPI listing is the cleaner pick on that axis), or your governance-sensitive investment use case is incompatible with the brokerage-tier custody arrangement at Toss Securities.
