Ultra-High-Yield ETF Taxes, Fully Explained
— Filing Basics for a Korean Investor
Ultra-high-yield ETFs like YieldMax and QYLD get taxed differently depending on the character of the distribution. We break down how it splits between dividend income tax, Return of Capital (ROC), and capital-gains tax.
The Ordinary-Dividend Portion — Dividend Income Tax
The part of the distribution that comes from options-premium profit or the underlying asset's own dividend gets classified as ordinary dividend income. After a 15% US withholding (under the Korea-US tax treaty), it's also subject to dividend-income reporting in Korea. If your combined financial income (interest plus dividends) exceeds 2,000-man-won (roughly KRW 20,000,000) a year, it becomes subject to comprehensive financial-income taxation, which can get combined with your other income and taxed together.
The Return-of-Capital (ROC) Portion — Deferred to Capital-Gains Tax
The part of a distribution classified as ROC isn't taxed when you receive it. Instead, it's handled by lowering your cost basis, which leads to a bigger capital gain later when you sell that ETF. In other words, the tax doesn't disappear — it gets deferred to capital-gains tax. The accounting meaning of ROC is covered in detail in covered-call principal erosion (ROC).
Capital-Gains Tax and the $1,900 (250-man-won) Deduction
The capital gain realized at sale (including the basis lowered by ROC) gets combined with your other US stock trading gains, with a basic annual deduction of up to 250-man-won (roughly $1,900), and a 22% rate (including local tax) applied to the excess. See the 250-man-won deduction tax-savings guide for the exact calculation method and timing strategy. You can also run your own simulation with the tax calculator.
Weekly Distributions Need More Bookkeeping
The tax principle itself is the same for monthly and weekly distributions. But with a weekly payout, roughly 50-odd distribution records pile up in 1 year, meaning you have more items to track and sum separately for the dividend-income portion and the ROC portion. It's common to check against the year-end summary your broker provides (Form 1099-DIV, and so on). See the complete guide to weekly-dividend ETFs (13 YieldMax funds) for the list of relevant products.
