Hva er Korea Gift & Inheritance Tax Calculator?

▾

Kalkulatoren Korea Gift Tax (증여세) og Inheritance Tax (상속세) hjelper koreanske skattebetalere å beregne skatten som skal betales ved mottak av eiendom overført som gave i løpet av livet eller som arv ved død. Korea opererer med noen av verdens høyeste gave- og arveskattsatser, med toppmarginalsatser som når 50 % på beløp over 3 milliarder KRW. Den samme progressive satsplanen gjelder for begge skatter: 10 % på skattepliktige beløp opp til KRW 100M, 20 % på KRW 100M til KRW 500M, 30% på KRW 500M til KRW 1B, 40% på KRW 1B til KRW 3B over, og KRW 3B over. For gaveavgift hindrer betydelige utelukkelsesbeløp beskatning av vanlige familiegaver: KRW 60M per 10-årsperiode for gaver til voksne barn (eller KRW 50M før voksen alder), KRW 60M for gaver fra barn til foreldre, KRW 100M for gaver mellom ektefeller og KRW 50M for gaver fra besteforeldre. Alle gaver fra samme giver samles over en 10-årsperiode før eksklusjon og progressive satser tas i bruk. For arveavgift gir systemet et grunnfradrag på KRW 200M, pluss ekstra ektefellefradrag opptil KRW 3B (eller faktisk arv, avhengig av hva som er lavest), barnefradrag på KRW 50M hver, og andre fradrag. De totale grunnekskluderingene lar ofte svært beskjedne eiendommer passere helt skattefritt.

Formel

▾
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

Slik Korea Gift & Inheritance Tax Calculator

▾
  1. 1For gift tax: aggregate all gifts from the same donor in the past 10 years.
  2. 2Subtract the applicable exclusion (KRW 60M for adult children, KRW 100M for spouses, etc.).
  3. 3Apply the progressive gift tax rate to the remaining taxable amount.
  4. 4Apply a 30% premium if the donor-recipient relationship includes ancestors (증여세 할증과세) — e.g., grandparent to grandchild.
  5. 5For inheritance tax: total the decedent's net estate (assets minus liabilities).
  6. 6Subtract applicable deductions (basic KRW 200M, spouse deduction, child deductions per heir).
  7. 7Apply the progressive inheritance tax rate to the taxable inheritance amount.

Løste eksempler

▾
Eksempel 1Parent gifting KRW 200M to adult child
Gitt:Gift KRW 200,000,000 to adult child, no prior gifts in 10 years
Resultat: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.

Eksempel 2Spouse receiving estate on inheritance
Gitt:Total estate KRW 2B, surviving spouse inherits all, 2 children as heirs
Resultat: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.

Eksempel 3Grandchild gift — 30% surcharge
Gitt:Grandparent gifts KRW 150M to grandchild
Resultat: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.

Eksempel 4Gifting over 10 years to maximise exclusion
Gitt:Parent plans to gift KRW 120M to adult child over 2 separate 10-year periods
Resultat: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.

Vanlige feil å unngå

▾
  • !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.
💡

Pro Tips

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.

Visste du?

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.
