South Korea comprehensive taxation of financial income (interest and dividends over 20 million KRW a year): compares the comprehensive method (first 20M at 14%, the excess added to other income at 6-45%) with the 14% separate method and takes the larger, then shows tax due beyond what was withheld. Dividend gross-up and the 2026 high-dividend separate-taxation option are not modeled.
