Who gave it

Donor's relationship to you (the recipient)

A parent's current (registered) spouse, such as a step-parent, counts as a lineal ascendant. Father and mother are treated as one donor for the 10-year aggregation and share one deduction limit.

Generation-skipping gift (grandparent → grandchild etc.)Adds 30% to the computed tax (40% if the recipient is a minor and the gifts exceed KRW 2 billion). No surcharge if the recipient's parent has died, so leave it off in that case.

Gift amounts

This gift (KRW)

Earlier gifts from the same donor within 10 years

If the total is KRW 10 million or more it is added to this gift and the tax is recomputed, with the tax computed on the earlier gifts credited back. For a parent, include gifts from the other parent too.

Tax computed on those earlier gifts (blank = estimate at current rates)

Deduction already used on gifts from other donors in the same group (10 years)

e.g. if KRW 20 million of the deduction was used on a gift from grandparents, only KRW 30 million is left for gifts from parents.

Marriage / birth deduction and filing

Apply the marriage / birth gift deductionGifts from a parent or grandparent within 2 years before or after the marriage registration date, or within 2 years of a child's birth or adoption. KRW 100 million for life, on top of the basic deduction.

Defaults follow Korea's Inheritance and Gift Tax Act as in force in October 2026 (version effective 2 Jan 2026): deductions Art. 53, marriage/birth deduction Art. 53-2 (gifts from 2024), rates Art. 26 and 56, 10-year aggregation Art. 47(2), surcharge Art. 57, filing credit Art. 69(2). Since 14 Mar 2025 "other relatives" means blood relatives within the 4th degree and in-laws within the 3rd. The government's 2024 proposal to cut the rates was not passed by the National Assembly.

This is an estimate for reference. It follows Korea's Inheritance and Gift Tax Act (2026 rules) for a resident recipient and property taxed at the basic rates (cash and similar). It does not cover gifts with assumed debt, valuation of property or shares, separately taxed gifts, start-up or family-business special rules, foreign tax credits or penalties. Confirm the real amount on the National Tax Service's Hometax filing screen or with the tax office. This is not tax advice.

What this tool does

Enter your relationship to the donor, the gift you received and earlier gifts from the same person within 10 years to estimate the Korean gift tax due under the Inheritance and Gift Tax Act (2026 rules). The table walks through the gift deduction, the marriage / birth deduction, 10-year aggregation, the generation-skipping surcharge, the credit for tax on earlier gifts and the 3% filing credit. Rates and limits can be edited under 'Edit the rules'.

How it is calculated

Taxable value = this gift + gifts from the same donor in the previous 10 years (a parent and their spouse count as one donor) when those total KRW 10 million or more. Tax base = taxable value − gift deduction (spouse KRW 600M; parent or grandparent → adult KRW 50M, → minor KRW 20M; child → parent KRW 50M; blood relatives within the 4th degree and in-laws within the 3rd KRW 10M; 10-year limits) − marriage / birth deduction (gifts from ascendants, KRW 100M for life); no tax if the base is under KRW 500,000. Computed tax = base × rate − quick deduction (up to 100M 10%; up to 500M 20% − 10M; up to 1B 30% − 60M; up to 3B 40% − 160M; above 50% − 460M). A gift that skips a generation adds 30% of the computed tax (40% for a minor receiving over KRW 2B), and tax computed on aggregated earlier gifts is credited up to 'tax × earlier base ÷ combined base'. Filing on time takes 3% off (tax + surcharge − earlier-tax credit), and the amount payable is rounded down to 10 won. Example: an adult child receives KRW 200M from a parent with no earlier gifts: 200M − 50M = base 150M; 150M × 20% − 10M = KRW 20M; minus the 600,000 filing credit = KRW 19.4M, which is what the page shows when it opens.

Choose the relationship. Parents and grandparents are both lineal ascendants; pick 'minor' if the recipient is under 19

Turn on 'generation-skipping gift' for gifts from grandparents (not if the recipient's parent has died)

Enter this gift and the total received from the same donor in the last 10 years (father and mother count as one)

Enter the tax computed on those earlier gifts if you know it; leave it blank to estimate at current rates

Turn on the marriage / birth deduction for gifts from ascendants within 2 years of the marriage registration or 2 years after a birth or adoption

Example: adult child, KRW 30M three years ago + KRW 50M now → 80M − 50M deduction = base 30M → tax 3M → filing credit 90,000 → KRW 2.91M

Things to know

The deduction is not renewed with each gift. All deductions from the same group (e.g. all lineal ascendants) over 10 years share one limit, so a deduction used on a gift from grandparents reduces what is left for gifts from parents.

Since 14 March 2025 'other relatives' means blood relatives within the 4th degree and in-laws within the 3rd degree; earlier gifts used the 6th and 4th degrees.

The marriage / birth deduction applies to gifts from 1 January 2024 and is on top of the basic deduction, so an adult child can receive up to KRW 150M from parents with a zero tax base. If the marriage does not follow within 2 years, an amended return is needed.

Filing even when no tax is due leaves a record that explains where the money came from.

If more than KRW 10M is payable you can pay part within 2 months; above KRW 20M you can apply for annual instalments (up to 5 years for ordinary gifts) with collateral.

Valuation of property or unlisted shares, gifts with assumed debt and start-up or family-business special rules are out of scope. The government's 2024 proposal to cut the rates did not pass, so the rates above still apply in 2026.

Frequently asked questions

How much can I receive from my parents tax-free in Korea?

Under the 2026 rules an adult child can deduct KRW 50 million in total over 10 years from lineal ascendants (KRW 20 million for a minor). Gifts within 2 years of the marriage registration or of a birth add a KRW 100 million marriage / birth deduction. Even above that, no tax is due if the tax base is under KRW 500,000.

Do I get the deduction twice if my father and mother each give me money?

No. The deduction is per recipient across all lineal ascendants (KRW 50 million over 10 years), and for aggregation a parent and their spouse count as one donor. KRW 100M from your father and KRW 30M from your mother are taxed as KRW 130M.

How are earlier gifts within 10 years handled?

If gifts from the same donor total KRW 10 million or more they are added to this gift and the tax is recomputed, and the tax computed on the earlier gifts is credited back. Splitting a gift therefore ends up in a similar bracket to giving it all at once. The credit has a legal cap.

What changes when a grandparent gives directly to a grandchild?

It skips a generation, so 30% is added to the computed tax, or 40% if the grandchild is a minor and receives more than KRW 2 billion. There is no surcharge if the grandchild's parent has already died.

When must the return be filed?

Within 3 months from the end of the month in which the gift was received, on the National Tax Service's Hometax or at the tax office. Filing on time gives a 3% credit on the computed tax (incl. surcharge) minus the earlier-tax credit; late filing loses it and adds penalties.
