Even for ETFs that track the S&P 500, the type and rate of tax on trading gains differ depending on where the product is listed.
Enter the principal, holding period, expected return and the distribution share of it.
Trading gains on a Korea-listed ETF are treated as dividend income, which affects whether comprehensive taxation of financial income applies in the year you sell.
See the after-tax amounts and tax breakdown of the two approaches side by side.
Not necessarily. If the trading gain is small or other financial income is low so that you don't exceed the KRW 20 million threshold, the tax ends at 15.4%, which can be lower than 22%. If you hold them in an ISA or pension account, you can also get tax deferral and low-rate taxation benefits.
Yes. The KRW 2.5 million basic deduction on overseas stock capital gains applies every year. You can also sell part each year and buy back to use the deduction, but this calculator assumes a single sale in the final year.
Trading gains on Korea-listed overseas-stock ETFs are taxed as dividend income, so they are included in financial income. If the gain is large in the year you sell, it can exceed KRW 20 million and be subject to comprehensive taxation.
If financial income exceeds KRW 10 million a year, the entire amount is counted as income for health insurance. If you are a dependent, also check with the comprehensive financial income tax and health insurance premium checker.
Both approaches assume the same return in KRW terms. Capital gains on US-listed ETFs are taxed on the gain converted into KRW, so if the exchange rate rises, the tax also rises.

Simulate how much you could sell before year-end to cut your tax, using the KRW 2.5 million basic deduction and netting of gains and losses.
Compare after-tax results when making the same investment in a regular account, ISA, pension savings account or IRP.
Check whether your interest and dividends exceed KRW 20 million and whether it affects your eligibility as a health insurance dependent.
