Taxes in South Korea, Part 1: Capital Gains, Inheritance, and Gifts

South Korean Taxes on Asset Transfers

This article discusses South Korea. The examples and institutions below are not guidance for US or other tax systems. Confirm current rules and your circumstances with the Korean tax authorities or a qualified adviser before acting.

When we give assets to someone else or receive them from another person, the taxes paid to the state can be summarized in three main categories: capital gains tax, inheritance tax, and gift tax. All three are imposed on the “movement of assets,” but their taxation methods and tax-saving tips differ completely depending on whether compensation was received and whether death is involved.

1. Capital Gains Tax

What Is Capital Gains Tax?

Concept: This is a tax imposed on the ‘market-price gain (capital gain)’ that arises when you dispose of (transfer) an asset—mainly real estate or stocks—for more than its purchase price (acquisition price).
Point: If there is no gain, there is no tax. If you sell at the price you paid or at a loss, capital gains tax is “0 won.” (You must still report it to the tax authority.)

The Key to Tax Saving: One Household, One Home Exemption

The crown jewel of capital-gains-tax planning is clearly ‘tax exemption.’

When one household transfers one home it has held for at least two years (with an additional two-year residence requirement in regulated areas), no capital gains tax is paid on a transfer value up to 1.2 billion won.
Joint ownership by spouses can split the capital gain in half and lower progressive tax rates (spread the tax base).

2. Inheritance Tax and Gift Tax

Inheritance and gifts are both acts of transferring assets to another person without compensation.

Comparison of Inheritance Tax and Gift Tax
Category	Inheritance Tax	Gift Tax
Cause	Death (death of the decedent)	Lifetime gift (while the donor is alive)
Taxation method	Estate-tax method (taxing the deceased person’s total remaining property)	Inheritance-acquisition-tax method (taxing each recipient according to what they received)
Basic deduction	At least 500 million won (at least 1 billion won basic deduction if a spouse survives)	600 million won for a spouse, 50 million won for an adult child, and 20 million won for a minor child (per 10-year period)

The Gift-Giving Technique: A 10-Year Cycle Reset

The gift-tax exemption limit (for example, 50 million won for a child) is not a once-in-a-lifetime benefit; it resets every 10 years. Therefore, giving a child 20 million won at birth, 20 million at age 10, 50 million at age 20, and 50 million at age 30 allows a total of 140 million won to be passed on without paying a single won of tax.

3. Advanced Topic: Carryover Taxation and Indirect Transfers (Denial of Unfair Transactions)

To prevent the “trick” of gifting an asset to a family member and immediately selling it to avoid capital gains tax, the law has two powerful weapons.

(1) Carryover Taxation for Spouses, etc. (Certain Assets)

Situation: A husband gives land with a large capital gain to his wife at 600 million won (the gift-tax deduction limit). The wife raises the land’s acquisition price to 600 million won without gift tax. Immediately afterward, she tries to sell it to a third party for 650 million won, greatly reducing the capital gain and avoiding tax.
The law’s hammer: If it is transferred within 10 years (revised in 2023; previously 5 years) of the gift date, the acquisition price is calculated (carried over) not as the value at which the wife received the gift, but as “the price the husband originally paid long ago,” resulting in heavier capital gains tax.

(2) Indirect Transfer (Denial of Unfair Transactions)

Situation: A method in which an asset is gifted to a related party other than a spouse, such as a sibling or niece/nephew, and that related party sells it to a third party within 10 years.
The law’s hammer: If the tax authority finds that the sum of “gift tax + capital gains tax paid by the recipient” is less than “the capital gains tax that would have been due had the original owner sold directly,” it denies the gift itself as though it never happened and treats the transaction as if the original owner had sold directly to the third party from the outset, imposing substantial capital gains tax and penalties.

4. Summary Tax-Saving Guide

Sell or give? If an excellent asset is rising sharply in value, it may be advantageous in the long term to give it away at as young an age as possible, even if gift tax is expensive.
Use a gift with assumed liabilities: When gifting a home, this means transferring to a child the lease deposit (an inclusive debt) or loan secured on the home as well. The child pays gift tax only on the net asset value after debt, while the donor pays some capital gains tax because the transferred debt is treated as having “sold (transferred)” the building; this can substantially reduce total tax.
