The old rule of thumb — "once dividends pass ₩20M you get hit with a comprehensive-taxation bomb" — starts to crack in 2026. If the dividend comes from a high-payout Korean listed company, you can now elect separate taxation (분리과세, "bunri-gwase") instead of comprehensive taxation, capping your rate at 30%. Here's who wins, who doesn't, with the numbers.

One-line summary
- A December 2025 amendment to the Tax Incentive Restriction Act applies this to dividends paid on or after January 1, 2026. It's a 3-year temporary rule (2026–2028)
- Eligible: dividends from high-payout listed companies — either a payout ratio of 40%+, or a payout ratio of 25%+ combined with a 10%+ increase in total dividends versus the prior year
- Separate-taxation rates: 14% up to ₩20M, 20% for ₩20M–300M, 25% for ₩300M–5B, 30% above ₩5B (local income tax extra)
- The bigger your dividends, the bigger the win — it caps the top rate of comprehensive taxation (45%) at 30%. For small investors with under ₩20M in dividends, almost nothing changes
What actually changes
The base structure of Korean dividend tax works like this. If your annual financial income (interest + dividends) is ₩20M or less, it's settled by 15.4% withholding — separate taxation (분리과세). Above ₩20M, the excess is added to your other income and taxed at progressive 6–45% comprehensive taxation (종합과세). The more dividends a wealthy investor collected, the higher the bracket they got pushed into.
The 2026 special rule inserts a new option into that second path. For dividends from qualifying high-payout companies, you can elect to apply a separate progressive rate table instead of folding them into comprehensive taxation. It's a follow-on tax measure to the government's corporate value-up program, aimed at expanding shareholder returns and easing the "Korea discount."
The key word is choice: you compare comprehensive vs. separate taxation and pick whichever is cheaper when you file your annual return (the following May).
Which "high-payout companies" qualify
Not every dividend stock counts. A listed company must meet one of two tests:
- Payout ratio of 40% or more — paid out 40%+ of that year's net profit as dividends
- Payout ratio of 25%+ AND total dividends up 10%+ year over year — companies steadily growing their payout
Payout ratio = dividends divided by net profit. Financial holding companies, telecoms, and certain value stocks with high shareholder-return ratios tend to clear the bar. Crucially, it applies only to dividends from Korean listed companies — dividends from US stocks or overseas ETFs are not eligible and stay under the old rules.
Whether a company qualifies is confirmed via disclosure, and the judgment can change year to year. A company eligible this year may drop out next year.
The rate table — 14% to 30%
If you elect it, a separate progressive schedule applies (income tax basis; add 10% local income tax).
| Qualifying dividend bracket | Income tax | With local tax |
|---|---|---|
| Up to ₩20M | 14% | 15.4% |
| ₩20M–300M | 20% | 22% |
| ₩300M–5B | 25% | 27.5% |
| Above ₩5B | 30% | 33% |
The point is the ceiling stops at 30% (33% with local tax). Under comprehensive taxation, those dividends could have stacked on your other income up to 45% (49.5% with local tax). Separate taxation halts at 30%.
Comprehensive vs. separate — who wins (worked example)
Say a high-earning employee already sits in a high income-tax bracket and receives ₩100M in dividends a year from high-payout stocks (assume all of it qualifies).
Choosing comprehensive taxation — the ₩100M piles on top of salary income and can hit the top bracket. At the top (49.5% with local tax), that's roughly ₩50M in tax on the ₩100M.
Choosing separate taxation — you compute it in brackets: ₩20M × 14% + ₩80M × 20% = ₩2.8M + ₩16M = ₩18.8M (income tax). With local tax, about ₩20.68M — an effective rate around 20%.
Same ₩100M, less than half the tax. The more other income you have (the higher your bracket), the bigger the separate-taxation advantage. (These figures are illustrative; your actual result depends on your other income and deductions.)
For small dividend earners, it's the opposite. If your annual dividends are ₩20M or less, you were already done at 15.4% withholding, and the first bracket of the separate table is also 14% (15.4%) — almost no difference. This rule is fundamentally a card for "people who collected enough dividends to land in high comprehensive-tax brackets."
The first step is to see how close your dividend income is to the ₩20M comprehensive-taxation threshold and how much your burden balloons once you cross it.

Watch-outs when you actually claim it
- You elect it at filing — at payout, 14% (15.4%) is withheld first; separate taxation is chosen the following May on your annual return. It's not automatic.
- Pick the cheaper side — comprehensive taxation can be cheaper. If your income is low and you sit in a low progressive bracket, comprehensive may win. Compare before deciding.
- Korean listed dividends only — overseas stocks and ETFs are excluded. Sort out which of your dividends qualify.
- Temporary — for now it runs only 2026–2028. It could be extended, or it could end.
- Health insurance is separate — lowering your income tax via separate taxation doesn't move the health-insurance premium base the same way. Don't decide on tax alone.

Bottom line
Korea's 2026 dividend separate taxation is a tax-saving card aimed at heavy dividend earners. For dividends from high-payout listed companies, you can choose 14–30% separate taxation instead of comprehensive taxation, and the higher your bracket, the more you save. For small investors under ₩20M, little changes. The two things to settle before filing: (1) whether your dividends are Korean-listed and from a qualifying high-payout company, and (2) which is cheaper — comprehensive or separate taxation.
