International gold prices exceeded $3,900 per troy ounce last October, setting a new all-time high, and the domestic price of one don (3.75 g) of gold also crossed 700,000 won — figures as reported by Toss Bank's gold investment guide. Money flowing into gold has increased, but the after-tax return differs depending on which account type you use to buy the same gold. The first choice in gold investing is not timing but the channel — here is a comparison of the four routes: physical gold bars, the KRX gold market, gold banking (gold savings accounts), and gold ETFs, using publicly available data on their tax and fee structures.
Four Routes — Different Tax Structures from the Start
Gold is a single asset class, but tax law views it differently depending on the route. According to a tax expert column in KB Think, physical gold bars carry a 10% value-added tax (VAT) at the time of purchase, but capital gains on resale are not taxed. Gold banking (gold savings accounts) and domestically listed gold ETFs are the opposite: no VAT on purchase, but capital gains are subject to 15.4% dividend income tax withholding at source. Physical gold adds the complication of storage. The risk of loss or theft must be self-managed or covered by a storage service, so costs beyond taxes must also be included in the route comparison.
Overseas-listed gold ETFs follow yet another track: after deducting 2.5 million won from the annual capital gain, a 22% capital gains tax applies as a separate levy. And the KRX gold market sits outside all of these tracks. As long as buying and selling stays within the account, the capital gain itself is not a taxable event.
| Investment Route | Tax on Capital Gains | VAT | Transaction Cost (%) |
|---|---|---|---|
| Physical gold bar | None | 10% on purchase | 0.3–2 |
| KRX gold market | Tax-exempt | 10% only on physical withdrawal | Approx. 0.3 |
| Gold banking (gold savings account) | Dividend income tax 15.4% | None | Approx. 1 |
| Domestically listed gold ETF | Dividend income tax 15.4% | None | Management fee additional |
| Overseas-listed gold ETF | 22% after 2.5 million won deduction | None | Management fee additional |
Even with the same rate of price appreciation, the amount you keep in hand differs by route. The gap in transaction costs is also hard to ignore. Based on Toss Bank guidance, fees for physical gold trading range from 0.3–2%, gold banking about 1%, and the KRX gold market about 0.3%. Comparing total costs — taxes plus fees combined — is needed to properly assess the advantages and disadvantages between routes.
KRX Gold Market — The Condition for Tax Exemption Is "Don't Withdraw"
The KRX gold market is a market where investors open a gold spot account at a securities firm and trade gold listed on the Korea Exchange like a stock. It is accessible in small amounts since trading is in 1-gram units, and capital gains are not subject to either capital gains tax or dividend income tax. It is also excluded from comprehensive financial income taxation.
However, the tax exemption comes with a condition. The moment you withdraw the account's gold as physical gold bars, a 10% VAT is levied, along with a withdrawal fee of roughly 20,000 won per unit based on Toss Bank guidance. This means the tax-advantaged structure favors completing trades within the account without physical withdrawal. This is fundamentally different from investing with physical possession itself as the goal.
Trading units also need to be kept in mind. International prices are quoted in troy ounces (approximately 31.1 g), and at domestic gold jewelry shops, one don (3.75 g) is the common unit. The KRX gold market quotes in 1-gram units — suitable for small, incremental purchases — and when comparing directly to international prices, a unit conversion is required.
Gold ETFs and Gold Banking — The Heavier Burden Beyond 15.4% Is Comprehensive Taxation
Capital gains on domestically listed gold ETFs and gold banking are subject to 15.4% dividend income tax withheld at source. If it ends there, the calculation is simple. The problem arises when total financial income from interest and dividends combined exceeds 20 million won per year. At that point, comprehensive financial income tax applies, aggregating with other income under progressive rates — and the higher the existing financial income, the greater the effective burden can be. Even investors holding the same product can have very different after-tax returns depending on whether withholding ends their obligation or they cross into comprehensive taxation.
Gold banking is a product where money deposited in a bank account accumulates gold in 0.01-gram increments in line with the market price. The barrier to entry for small, incremental savings is low, but when factoring in capital gains taxation and approximately 1% transaction fees, costs accumulate with frequent trading.
Overseas-listed gold ETFs differ in that they are subject to capital gains tax as a separate levy rather than dividend income. After a 2.5 million won annual deduction, 22% applies — so the actual burden is not large if the gain is small, but as gains grow, a bracket emerges where it becomes heavier than the 15.4% on domestic ETFs. This is why your expected gain size and your other financial income must be considered together in the calculation.
In gold investing, the first variable that splits returns is not the price but the account — even in the same bull market, the tax collected differs by route.
What to Watch
The recent gold price rally is attributed to central bank buying and safe-haven demand. Domestically, surging demand has even created a so-called "kimchi premium" where domestic gold prices exceed international prices. However, this premise is conditional. If the dollar turns stronger or interest rates rise again, the relative appeal of gold — an asset that yields no interest — could decline. Conversely, for small investors unconcerned with comprehensive taxation, transaction fees and trading convenience may be larger variables than tax differences. The following items, checked regardless of which route you choose, help establish a judgment framework.
- Whether your annual financial income is close to 20 million won — whether comprehensive taxation applies is the starting point for route selection
- The gap between domestic and international gold prices — buying when the kimchi premium is large means paying that much more
- Plans for physical withdrawal — the moment you withdraw, the KRX gold market's tax-exempt advantage is offset by 10% VAT
- Dollar exchange rate and US interest rate direction — the conditions under which the gold price bull case breaks down
- Total of transaction fees and management costs — compare routes based on total cost, not just taxes
