Cos'è Korea Gift & Inheritance Tax Calculator?

▾

The Korea Gift Tax (증여세) and Inheritance Tax (상속세) calculator helps Korean taxpayers estimate the tax owed on the receipt of property transferred as a gift during a lifetime or as inheritance upon death. Korea operates some of the world's highest gift and inheritance tax rates, with top marginal rates reaching 50% on amounts above KRW 3 billion. The same progressive rate schedule applies to both taxes: 10% on taxable amounts up to KRW 100M, 20% on KRW 100M to KRW 500M, 30% on KRW 500M to KRW 1B, 40% on KRW 1B to KRW 3B, and 50% above KRW 3B. For gift tax, significant exclusion amounts prevent taxation of ordinary family gifts: KRW 60M per 10-year period for gifts to adult children (or KRW 50M before adulthood), KRW 60M for gifts from children to parents, KRW 100M for gifts between spouses, and KRW 50M for gifts from grandparents. All gifts from the same donor are aggregated over a 10-year period before applying the exclusion and progressive rates. For inheritance tax, the system provides a basic deduction of KRW 200M, plus additional spouse deduction up to KRW 3B (or actual inheritance, whichever is lower), child deductions of KRW 50M each, and other deductions. The total basic exclusions often allow very modest estates to pass entirely tax-free.

Formula

▾
f(x)Gift Tax = (Total 10-year gifts from same donor - Exclusion) × Progressive Rate; Inheritance Tax = (Total Estate - Basic KRW 200M - Spouse Deduction - Child Deductions - Other) × Progressive Rate; Both taxes use same 10%–50% rate schedule

Esempi risolti

▾
Esempio 1Parent gifting KRW 200M to adult child
Dato:Gift KRW 200,000,000 to adult child, no prior gifts in 10 years
Risultato:Taxable gift: KRW 200M - KRW 60M exclusion = KRW 140M; Tax: 10% on KRW 100M + 20% on KRW 40M = KRW 18M

Exclusion KRW 60M for direct adult descendants

After the KRW 60M exclusion, KRW 140M is taxable. The progressive rate gives KRW 18M in gift tax. The child must self-declare and pay within 3 months of receiving the gift.

Esempio 2Spouse receiving estate on inheritance
Dato:Total estate KRW 2B, surviving spouse inherits all, 2 children as heirs
Risultato:Basic deduction: KRW 200M; Spouse deduction: min(spouse's share, KRW 3B) + minimum KRW 500M = assumed KRW 1B; Child deductions: 2 × KRW 50M = KRW 100M; Taxable: KRW 2B - KRW 1.3B = KRW 700M; Tax: ~KRW 130M

Spouse deduction is very generous in Korean law

The spouse deduction significantly reduces taxable inheritance. On KRW 2B estate with spouse and 2 children, over KRW 1.3B is excluded, leaving KRW 700M taxable.

Esempio 3Grandchild gift — 30% surcharge
Dato:Grandparent gifts KRW 150M to grandchild
Risultato:Exclusion: KRW 50M (grandchild of lineal descendant); Taxable: KRW 100M; Tax: KRW 10M; 30% surcharge: KRW 3M; Total: KRW 13M

Skipping-generation gifts attract 30% surcharge

Gifts from grandparents to grandchildren attract a 30% generation-skipping surcharge on top of the base gift tax, because they skip an intermediate generation. This discourages estate planning strategies that bypass one generation.

Esempio 4Gifting over 10 years to maximise exclusion
Dato:Parent plans to gift KRW 120M to adult child over 2 separate 10-year periods
Risultato:Period 1: KRW 60M gift - KRW 60M exclusion = KRW 0 taxable; Period 2 (10 years later): same; Total gift KRW 120M with zero gift tax

Strategic 10-year spacing uses full exclusion each period

By timing gifts to use the full KRW 60M exclusion every 10 years, parents can transfer significant wealth tax-free. KRW 120M over 20 years to one child incurs zero gift tax if properly timed.

Q

What is the top gift and inheritance tax rate in Korea?

A

Korea Gift Inheritance Tax is a specialized calculation tool designed to help users compute and analyze key metrics in the finance and tax domain. It takes specific numeric inputs — typically drawn from real-world data such as measurements, rates, or quantities — and applies a validated mathematical formula to produce actionable results. The tool is valuable because it eliminates manual calculation errors, provides instant feedback when exploring different scenarios, and serves as both a decision-support instrument for professionals and a learning aid for students studying the underlying principles.

Q

When must gift tax be filed?

A

Use Korea Gift Inheritance Tax whenever you need a reliable, reproducible calculation for decision-making, planning, comparison, or verification in finance and tax. Common triggers include evaluating a new opportunity, comparing two or more alternatives, checking whether a quoted figure is reasonable, preparing documentation that requires precise numbers, or monitoring changes over time. In professional settings, recalculating regularly — especially when key inputs change — ensures that decisions are based on current data rather than outdated estimates.

Q

How is the value of gifted or inherited property determined for tax purposes in Korea?

A

The value of gifted or inherited property in Korea is typically determined by its fair market value at the time of the gift or inheritance. For real estate, this is usually based on the officially assessed value, which can be found on the property tax bill or by contacting the local tax office. The fair market value can also be determined through an independent appraisal, especially for unique or high-value items such as artwork or businesses.

Q

Are there any exemptions or deductions available to reduce the amount of gift and inheritance tax owed in Korea?

A

Yes, there are several exemptions and deductions available to reduce the amount of gift and inheritance tax owed in Korea. For example, gifts or inheritances between spouses or direct relatives are exempt from tax up to a certain amount, which is currently 500 million KRW for spouses and 200 million KRW for other direct relatives. Additionally, donations to certain qualified charitable organizations may also be deductible.

Q

Can gift and inheritance tax be paid in installments, and if so, what are the terms and conditions?

A

Yes, gift and inheritance tax in Korea can be paid in installments under certain conditions. The taxpayer must submit an application for installment payment within 6 months of the original tax due date, and the total amount of tax owed must be at least 10 million KRW. The tax authority may approve installment payments over a period of up to 5 years, with interest charged on the outstanding balance at a rate of 4.5% per annum.

Errori comuni da evitare

▾
  • !Not filing gift tax returns on time — the 3-month deadline is strict and late filing penalties apply immediately.
  • !Not tracking 10-year cumulative gifts from the same donor — taxable amounts are aggregated and large gifts in the same period can suddenly push into higher brackets.
  • !Assuming life insurance death benefits are fully exempt — they may be included in the taxable estate.
  • !Undervaluing property gifts using lower assessed values — the NTS uses market values, not assessment values, for gift tax purposes.
  • !Gifting to children without considering the 10-year lookback for inheritance — pre-death gifts reenter the estate calculation.
💡

Consiglio Pro

Plan gifts at regular 10-year intervals to fully utilise the exclusion in each period. For a parent with two adult children, gifting KRW 60M to each child every 10 years generates zero gift tax on KRW 120M per decade — KRW 240M over 20 years — without any tax liability. Add the spouse exclusion of KRW 100M and you can transfer KRW 340M tax-free per decade through strategic annual planning.

Lo sapevi?

Korea's 50% top inheritance and gift tax rate is among the world's highest, alongside Japan and Belgium. However, unlike many countries, Korea's estate tax is not just on the wealthy — the rapid rise in Seoul property values over the past decade has brought many ordinary middle-class families into inheritance tax territory. A single Seoul apartment worth KRW 2B now represents a potential inheritance tax liability that would have been unimaginable when the parents bought the property for KRW 200M in the 1990s.
