In 2026 the Korean government is pushing a “Productive Finance ISA” (생산적 금융 ISA) — a broader framework that aims to expand Korea’s flagship tax-advantaged investment account. Within that framework, two sub-types are being discussed: National Growth ISA (국민성장 ISA) and Youth ISA. The press collectively calls this push the “Super ISA.” As of May 2026, however, the exact launch date, contribution limits, and tax-free caps are not yet finalized. This guide explains what is currently on the table, how it differs from the existing ISA, and which numbers are still proposals rather than law.
2026 ISA Reform Proposals at a Glance
Three separate strands are in motion in 2026:
- Productive Finance ISA (the framework): A new ISA category for capital flowing into “productive” domestic equity and funds. The framework splits into two sub-types:
- National Growth ISA: No age or income cap. Can reportedly be held alongside an existing ISA, but cannot be stacked with a Youth ISA.
- Youth ISA: Ages 19–34, annual salary ≤ KRW 75 million. Adds a contribution-based income tax deduction on top of the expanded ISA benefits. Deduction rate and cap subject to final tax law.
- National Growth Fund (separate scheme): A public participation fund whose retail tranche went on sale on May 22, 2026. Separate from the Productive Finance ISA, but often mentioned together because it can also be held inside an ISA account.
The market label “Super ISA” refers to this Productive Finance ISA push (covering both National Growth ISA and Youth ISA). It is a press and market nickname; government press releases use “Productive Finance ISA” and the two sub-type names.
A 2024 tax law amendment proposal had included a “Domestic Investment ISA” that would let high-income earners (comprehensive financial income taxpayers) open an ISA. That proposal was not passed by the National Assembly in December 2024, and ISA rules stayed as they were. In 2026 the government is taking another run at expansion through the Super ISA and Youth ISA — these are related but separate from the 2024 proposal.
Super ISA limits, tax-free caps, and the launch date are all proposed figures or government announcements — not finalized rules as of May 2026. Recheck the latest official numbers right before opening an account.
Quick Review: Current ISA (as of May 2026)
Before looking at the proposals, here’s a quick recap of how the current ISA works. It comes in two forms based on income eligibility. For a deeper comparison of General, Workforce, and Youth ISAs and the brokerage/trust/discretionary management styles, see our ISA Account Types Guide.
| Category | General Type | Workforce Type |
|---|---|---|
| Eligibility | Resident aged 19+, or aged 15+ with employment income | General eligibility plus annual salary ≤ KRW 50M (employees) or comprehensive income ≤ KRW 38M (self-employed) |
| Annual contribution limit | KRW 20 million | KRW 20 million |
| Lifetime contribution limit | KRW 100 million | KRW 100 million |
| Tax-free profit cap | KRW 2 million | KRW 4 million |
| Tax rate on excess | 9.9% separated tax | 9.9% separated tax |
| Mandatory holding period | 3 years | 3 years |
| Carry-forward of unused limit | Allowed | Allowed |
| Opening and renewal restriction | If you were classified as a comprehensive financial income taxpayer in any of the three tax years preceding the opening or renewal date, both opening and renewing the ISA are barred | |
The main advantage is the tax-free profit cap and reduced tax rate on excess profits. Interest and dividends in a regular Korean account are subject to 15.4% withholding (14% income tax + 1.4% local tax). Inside an ISA, the first KRW 2–4 million in net profit is tax-free, and amounts above that are taxed at 9.9% — separated from your other income.
※ A Farmer/Fisher ISA variant also exists with a KRW 4 million tax-free cap for eligible residents. This guide focuses on the General and Workforce types most commonly compared by general investors.
The current ISA already allows carry-forward of unused annual limits. For example, if you only contribute KRW 10 million of the KRW 20 million annual limit this year, the unused KRW 10 million rolls into next year — letting you contribute up to KRW 30 million in that year. This is a commonly misunderstood point and worth confirming upfront.
Another benefit is loss offset. Inside an ISA, if Product A gains KRW 1 million and Product B loses KRW 300,000, tax is calculated only on the net KRW 700,000. In a regular account, you’d still pay tax on the full KRW 1 million from Product A.
Super ISA (National Growth ISA) — What’s in the Proposal
The direction of the Super ISA proposal is clear: significantly raise both contribution and tax-free limits so the ISA becomes a true all-in-one savings vehicle. The numbers below are currently proposed figures — they only become final once the National Assembly passes the related tax law amendment.
| Category | Current ISA (General) | Super ISA Proposal (not finalized) |
|---|---|---|
| Annual contribution limit | KRW 20 million | KRW 40 million proposed (2× expansion) |
| Lifetime contribution limit | KRW 100 million | KRW 200 million proposed |
| Tax-free profit cap | KRW 2 million | Discussion centers on up to KRW 10 million |
| Mandatory holding period | 3 years | 3 years (expected to stay) |
| Eligibility | Resident aged 19+ (or 15+ with employment income) | Age/income restrictions to be relaxed (proposed) |
| Hold alongside existing ISA | One ISA per person rule | Separate account discussed — to be confirmed via implementing rules and brokerage systems |
| Carry-forward of unused limit | Allowed | Allowed (on a larger limit) |
The most attention-grabbing change is the expanded tax-free cap. Lifting it from KRW 2 million to around KRW 10 million would dramatically increase tax savings at the same profit level — if finalized.
For example, suppose your ISA produces KRW 8 million in net profit. Under the current General ISA, you subtract the KRW 2 million tax-free amount and pay 9.9% on the remaining KRW 6 million — about KRW 594,000 in tax. Under a Super ISA with a KRW 10 million cap, that same profit would be entirely tax-free. Again — this number is still a proposal.
Carry-forward itself is not a new Super ISA feature — the current ISA already allows it. What the Super ISA proposes is a larger annual limit (KRW 40 million instead of KRW 20 million), which would mean the size of unused room that can roll forward also grows.
The exact tax-free cap, separated tax rate, and launch date of the Super ISA will only be finalized after the National Assembly passes the related tax law amendment. The government has indicated direction (“significantly larger than the current ISA”) but not exact figures. Confirm the latest official numbers at launch.

Youth ISA — Proposal Direction
A separate Youth ISA is also being pushed. Residents aged 19–34 with an annual salary of KRW 75 million or less would receive special tax treatment on interest and dividends plus an income tax deduction on contributions. Press reports suggest a 10% deduction with a KRW 2 million annual cap, but the actual rate and cap depend on the final tax law.
- Eligibility: Ages 19–34, annual salary ≤ KRW 75 million (proposal basis)
- Proposed benefits: Super ISA-level limits plus a contribution-based income tax deduction (rate and cap not yet final)
- Combination rules: Current government materials indicate Youth ISA and National Growth ISA cannot be stacked, while the National Growth ISA may be held alongside an existing ISA. Actual account-count limits and brokerage system rollout will be confirmed once implementing rules are issued
For young residents, the additional deduction on top of tax-free growth could make this version more attractive than the others. Run the comparison yourself once the final deduction rate and cap are announced.
How This Differs from the 2024 “Domestic Investment ISA” Proposal
The 2024 tax law amendment proposal included a Domestic Investment ISA that would have let comprehensive financial income taxpayers open an ISA, with a KRW 10 million tax-free cap (KRW 20 million for the Workforce variant). However, this proposal was not adopted when the National Assembly voted on the package in December 2024 — ISA rules stayed unchanged.
The 2026 Super ISA and Youth ISA are the next attempt in the same direction, but the names and structures are different — don’t conflate the two. In particular, whether high-income earners will be allowed to open an ISA was part of the 2024 proposal but was not adopted; whether it returns in the 2026 package is still unclear.

National Growth Fund Is a Separate Scheme
The Super ISA is frequently confused with the National Growth Fund (국민성장펀드). They are different programs.
- Launch: The retail tranche went on first-come sale from May 22 to June 11, 2026. Separate from the ISA reform.
- Scale: The 2026 retail tranche is KRW 600 billion, sold through 10 banks and 15 brokerages. The broader National Growth Fund policy plans full-scale investment of about KRW 30 trillion in 2026, with the wider government investment vision being even larger — but those are separate from the retail product.
- Investment scope: AI, semiconductors, batteries, biotech, and other frontier industries.
- Principal protection — NOT what it sounds like: The fund has a “subordinated fiscal cushion” structure in which government capital sits in the first-loss tranche and absorbs up to 20% of losses per sub-fund. This is not a principal guarantee for individual investors. The product is classified as a Grade-1 high-risk investment by the Financial Services Commission. A 9% separated dividend tax and an income tax deduction (up to KRW 18 million) may apply.
- Relation to the ISA: You can subscribe via a dedicated account, a regular account, or an existing ISA — limits and tax benefits differ by channel. The dedicated account caps personal investment at KRW 100 million per year and KRW 200 million across five years. Compare with your bank or brokerage before deciding which channel suits you. Whether a future National Growth ISA will pair more directly with this fund remains unconfirmed.
In short, what actually launched in May 2026 is a fund, not an ISA. Any headline saying “Super ISA launches in May/June” likely confuses the two programs.
Which ISA Will Fit You?
A precise comparison will be possible only after the rules are finalized. Based on what is currently proposed, here are common scenarios.
Scenario 1. Office worker in their 30s (salary KRW 55 million)
If you are 34 or younger, look at the Youth ISA first — Super ISA-level limits plus a potential income tax deduction. If you are 35 or older, the Super ISA (National Growth ISA) is the leading candidate.
Scenario 2. Self-employed in their 40s (comprehensive income KRW 35 million)
You qualify for the current Workforce ISA (comprehensive income ≤ KRW 38 million), so a reasonable path is to use the Workforce ISA today (KRW 4 million tax-free cap) and revisit when the Super ISA arrives. Whether Workforce-style benefits will carry over into the Super ISA will be confirmed at launch.
Scenario 3. Anyone classified as a comprehensive financial income taxpayer in the past 3 years
You cannot open the current ISA. The 2024 Domestic Investment ISA that would have opened this door was not adopted. Whether the 2026 Super ISA package will reopen this path is still uncertain — wait for the implementing rules and tax law update.
Scenario 4. Hard to contribute a fixed amount every month
Even today’s ISA lets you carry forward unused room, so you can already make a larger deposit when a bonus arrives. If the Super ISA raises the annual limit, the size of carry-forward room grows too — keeping this benefit useful for irregular contributors.
Pre-Opening Checklist for the Super ISA Proposal
- Age: 19–34 → check the Youth ISA first. 35+ → Super ISA leads.
- Income bracket: Annual salary ≤ KRW 50M (employees) or comprehensive income ≤ KRW 38M (self-employed) → meets the current Workforce eligibility. Whether the same applies inside the Super ISA will be confirmed at launch.
- Financial income history: Anyone who was a comprehensive financial income taxpayer in any of the previous 3 tax years is barred from the current ISA. It is still unclear whether the 2026 package eases this restriction.
- Combination rules: The current ISA is one-per-person. Whether the Super ISA may be opened as a separate account will be confirmed when implementing rules and brokerage systems go live.
- 3-year holding: If you close the ISA before the mandatory holding period, prior tax benefits may be clawed back. Statutory exceptions exist for unavoidable reasons such as natural disasters, retirement, 3+ months of hospitalization, death, or emigration. Confirm with your bank or brokerage before closing.
- Account style: Brokerage for direct trading, Trust for deposits, Discretionary for hands-off. The same structure is expected for the Super ISA.
- Launch timing: The Super ISA is under discussion — no firm launch date. Reconfirm with the government and your bank or brokerage right before opening.
Frequently Asked Questions
Q1. When does the Super ISA launch?
As of May 2026, there is no confirmed launch date. Some reports mention June or later, but the exact timing depends on tax law passage and implementing-rule preparation. Check with the government and your bank right before opening.
Q2. Should I close my current ISA and switch to the Super ISA?
If your existing ISA has cleared its three-year holding period, you can close it at maturity and start fresh. If it is still inside the holding period, generally it is safer to keep it open and wait for the Super ISA. Whether the Super ISA can be held as a separate account alongside the current one will be confirmed in the implementing rules.
Q3. Is the KRW 10 million tax-free cap confirmed?
No. The government has signaled only that the cap will be “significantly higher than the current ISA,” with KRW 10 million as the leading proposal. The final number will be set when the tax law amendment passes.
Q4. If I buy into the National Growth Fund that launched in May, did I open a Super ISA?
No. The National Growth Fund is a policy investment fund, separate from the ISA reform. You can hold the fund inside your existing ISA, but doing so is not the same as opening a Super ISA.
Wrap-up
Super ISA, National Growth ISA, Youth ISA, Domestic Investment ISA, National Growth Fund — the names alone are confusing. The cleanest summary: what actually launched is the National Growth Fund (May 2026); all the ISA proposals are still being pushed and discussed. Numbers like KRW 40 million annual / KRW 200 million lifetime / KRW 10 million tax-free are leading proposals, not final figures.
Two things to do now: first, use the existing ISA’s carry-forward feature to fill up your current allowance efficiently. Second, wait for the tax law amendment to pass and implementing rules to come out before deciding whether to open a Super ISA. Right before opening any account, recheck the latest guidance from the Financial Services Commission ISA Q&A or your bank/brokerage.
