The Short Answer

Yes, prior gifts made within 10 years before the deceased’s death are included in the inheritance tax calculation in South Korea.

What the Law Says

South Korean inheritance tax law treats certain lifetime gifts as part of the taxable inheritance estate if they were made shortly before death.

Under the Inheritance and Gift Tax Act, any gift received from the deceased within 10 years before their death is added back to the inheritance tax base. This 'add-back rule' prevents tax avoidance through pre-death gifting.

The law applies regardless of whether the gift was reported or taxed at the time — it is automatically included in the heir’s inheritance tax calculation unless specifically exempted.

A basic deduction of ₩20 million applies to the total taxable inheritance (including add-backed gifts), and a separate ₩50 million gift exemption may apply per donor-recipient pair for gifts made more than 10 years before death — but not for those within the 10-year window.

What to Do

1

Gather records of all gifts received from the deceased within the past 10 years (bank transfers, real estate registrations, gift affidavits).

2

Report those gifts on the inheritance tax return (Form 401) along with inherited assets.

3

Apply the ₩20 million basic deduction and verify whether any portion qualifies for other statutory exemptions.

4

File the inheritance tax return within 6 months of the date of death.

5

Pay any tax due by the filing deadline — late payment incurs penalties and interest.
