Say you want ₩10M/month (₩120M/yr) of cash flow in retirement. There are two ways: ① build a portfolio of dividend stocks/ETFs and receive dividends, or ② sell shares bit by bit to fund living costs — the homemade dividend. Either way the cash lands in your pocket the same, but the tax is computed completely differently. And the winner flips depending on whether you hold Korean or US (overseas) stocks. Let's run the numbers precisely under Korea's 2026 tax rules.

The core difference: dividends are "income," selling is "capital gain"
The reason the tax diverges is that the two fall into different tax categories.
- Dividends = dividend income → subject to financial income aggregate taxation (금융소득종합과세); the portion above ₩20M/yr is added to your other income and taxed at progressive rates.
- Homemade dividend (selling) = capital gain → tax-free for Korean small shareholders; 22% schedular (separate) tax for overseas stocks.
The key: selling taxes only the gain, not your principal. If you sell ₩10M and only ₩3M of it is profit, tax is computed on the ₩3M alone. A ₩10M dividend, by contrast, is income in full, so the whole amount is taxed.
Korean stocks: homemade dividend wins by a landslide
Suppose you fund ₩120M/yr from Korean stocks.
| Receive dividends | Homemade dividend (sell) | |
|---|---|---|
| Tax method | Financial income aggregate tax (progressive) | Small-shareholder capital gains tax = 0 + transaction tax |
| Tax (on ₩120M) | ~₩24.6M | ~₩240K (0.20% transaction tax) |
| Effective rate | ~20.5% | ~0.2% |
Taking ₩120M as dividends pushes the portion above ₩20M into your aggregate income, hit by progressive rates (up to 49.5% incl. local tax). Under Korea's comparative-tax method (비교과세), the effective rate works out to about 20.5% — roughly ₩24.6M in tax.
The homemade dividend, by contrast, faces zero capital gains tax for small shareholders. Korean-listed stocks have no tax on capital gains unless you're a "major shareholder" (e.g., holding ₩5B+ per stock). All that's left is the 0.20% securities transaction tax (on KOSPI: 0.05% transaction tax + 0.15% rural special tax) on sale — just ₩240K even on ₩120M.
Bottom line: for Korean stocks, the homemade dividend almost always wins. Dividends turn sharply unfavorable the moment they cross ₩20M and enter aggregate taxation.
US stocks: homemade dividend still wins, but "schedular tax" is decisive
US (overseas) stocks change the math. Same ₩120M/yr, assuming 30% of the sale amount is gain.
| Receive dividends | Homemade dividend (sell) | |
|---|---|---|
| Tax method | US 15% withholding + Korea aggregate tax (foreign tax credit) | 22% schedular (separate) capital gains tax |
| Tax (30% gain) | Aggregate progressive (>₩20M added) | (₩36M − ₩2.5M) × 22% = ~₩7.37M |
| Key point | Gets heavier as the amount grows (progressive) | Flat 22% on the gain only, kept apart from other income |
US dividends are first withheld 15% in the US, then taxed again as dividend income in Korea — with a foreign tax credit to relieve double taxation. Above ₩20M, they join aggregate taxation at progressive rates.
The homemade dividend is fundamentally different. Overseas capital gains are NOT aggregated with financial income — they face a flat 22% schedular (separate) tax. Only the gain (after a ₩2.5M/yr basic deduction) is taxed at 22%, and the rate stays 22% no matter how large the amount. A ₩36M gain costs (₩36M − ₩2.5M) × 22% = ~₩7.37M, full stop.
Why the 22% schedular tax on US stocks is so powerful
This is what makes the homemade dividend strong. Schedular taxation is not aggregated with other comprehensive income. No matter how high your salary or business income, no matter how much other financial income you have, the overseas capital gains tax stands alone at 22%. The rate never spirals up via progression on large amounts — the exact opposite of dividends, which can be dragged up to 49.5% under aggregate taxation.

2026~2028 high-dividend separate tax: a temporary break that eases dividend burden
Here's a twist: a temporary high-dividend separate taxation runs from 2026 to 2028.
- Eligible: companies with a payout ratio of 40%+, OR (payout ratio 25%+ AND dividends up 10%+ vs prior year), that have disclosed a "value-up" (corporate value enhancement) plan.
- Rates (incl. local tax): ≤₩20M 15.4% / ₩20M
300M 22% / ₩300M5B 27.5% / >₩5B 33% - You can elect separate taxation instead of aggregation (favorable for high earners).
Applying this, the tax on a ₩120M dividend drops to about ₩25.08M (₩20M × 14% + ₩100M × 20%, then ×1.1) — lighter than ordinary aggregate taxation. But not every dividend qualifies. Only dividends from eligible high-dividend / value-up companies count; ordinary dividends still go through aggregate taxation.
Crossover: when do dividends become the better choice?
The rule of thumb:
- Homemade dividend tax is driven by the gain ratio × amount (less gain = less tax).
- Dividend tax is driven by the progressive aggregate taxation on the amount (bigger amount = heavier progression).
So the larger the amount and the lower the gain ratio, the more the homemade dividend wins. Conversely, even for US stocks, if the gain ratio is very high (70%+) and the amount is small (≤₩20M/yr), the story flips. In that band, dividends settle at 15.4% separate taxation, which can beat paying 22% on most of the gain via selling.
For example, ₩15M/yr of US dividends stays under ₩20M and settles at 15.4% — about ₩2.31M tax. The same amount sold at an 80% gain ratio costs (₩12M − ₩2.5M) × 22% = ~₩2.09M. Here the homemade dividend edges ahead, but if the gain ratio climbs higher or you've already used your deduction, dividends overtake. The best way to find your exact crossover point is to run it in the calculator.

Summary
- Korean stocks: small-shareholder capital gains tax is 0 → homemade dividend almost always wins. Dividends turn sharply unfavorable above ₩20M under aggregate taxation.
- US stocks: the homemade dividend's 22% schedular tax is kept apart from other income, so the rate stays fixed even on large amounts → overwhelmingly favorable when the gain ratio is low.
- Exception: even for US stocks, a small amount (≤₩20M) with a very high gain ratio can make the dividend's 15.4% separate taxation the winner.
- 2026~2028 high-dividend separate tax: for eligible companies' dividends, the dividend burden falls in high-income brackets, narrowing the gap.
The figures here are a simplified model. In reality, your other comprehensive income, the Korean dividend gross-up (배당가산), foreign tax credit limits, FX gains, and loss offsetting all change the outcome. Run your own situation through the tool for an accurate comparison.
