Calculate Korean inheritance tax and gift tax based on 2026 tax law. Includes tax bracket application, various deductions, and filing tax credit. Based on the South Korean Inheritance Tax and Gift Tax Act.
The results of this calculator are estimated taxes and may differ from actual tax liability.
Actual tax amounts can vary significantly depending on property valuation methods, detailed deduction items, and penalty tax applicability. For accurate tax calculation, please consult a tax professional or the Korean National Tax Service (126).
Choose Inheritance Tax or Gift Tax. Inheritance tax is levied when property is transferred upon death, while gift tax is levied on gratuitous transfers during the donor's lifetime. Both use the same tax brackets but differ in deductions. Based on South Korean tax law.
For inheritance tax, enter total assets, pre-gifted assets, debts, funeral costs, and financial assets. All amounts are in units of 10,000 KRW (man-won). For gift tax, enter the gift value and cumulative gifts from the same donor within 10 years for accurate aggregate taxation.
For inheritance tax, choose between lump-sum deduction (500M KRW) or individual deduction (basic 200M + personal). Spouse deduction (min 500M ~ max 3B KRW) can dramatically reduce tax. Gift tax deductions are automatically applied by relationship: spouse 600M, adult child 50M, minor child 20M KRW per 10-year period.
View taxable value, deductions, taxable base, computed tax, and final tax at a glance. The applicable tax bracket is highlighted. For inheritance tax, lump-sum vs individual deduction comparison is provided to show which is more advantageous. Filing tax credit (3%) is also applied.
When a Seoul apartment (market value 1B KRW) is inherited by a spouse and 2 children, applying lump-sum deduction (500M) + spouse deduction (500M) brings the taxable base to 0, resulting in no inheritance tax. Without a spouse, the taxable base becomes 500M KRW with approximately 80M KRW in tax. The spouse's presence creates a massive tax difference.
When a parent gifts 100M KRW to an adult child, applying the 50M KRW lineal ascendant deduction results in a 50M KRW taxable base at 10% rate = 5M KRW computed tax. After 3% filing credit, final tax is about 4.85M KRW. Gifting 50M KRW every 10 years enables tax-free wealth transfer under Korean law.
Gifting 800M KRW real estate to a spouse, with 600M KRW spouse deduction, creates a 200M KRW taxable base at 20% rate (progressive deduction 10M). Computed tax of 30M KRW minus filing credit = about 29.1M KRW. Spouse deduction is cumulative up to 600M over 10 years. Note: acquisition tax also applies to real estate gifts.
A person with 3B KRW assets gifting 50M KRW each to 3 children (150M total) pays zero gift tax as each falls within the 50M deduction. Repeating after 10 years doubles the tax-free transfer. Pre-gifting reduces the estate subject to high brackets (40-50%), potentially saving hundreds of millions in tax. Note: gifts within 10 years before death are added back to the inheritance tax base.
Gift tax exemption limits (spouse 600M, adult child 50M, minor 20M KRW) reset every 10 years under Korean law. Planned distributed gifting over time moves assets from high inheritance tax brackets (40-50%) to lower brackets, significantly reducing overall tax burden.
Inheritance spouse deduction ranges from 500M to 3B KRW. The spouse must actually inherit and the estate division must be completed within the filing deadline. Maximizing spouse deduction greatly reduces inheritance tax, but consider secondary inheritance tax when the spouse eventually passes.
Financial assets (deposits, stocks, insurance) in the estate qualify for up to 200M KRW deduction. Many people overlook this. Net financial assets under 20M get full deduction; over 100M get 20% (max 200M). Always check estate composition for this Korean tax benefit.
Filing inheritance tax within 6 months of death, or gift tax within 3 months of the gift date, earns a 3% credit on computed tax. For a 1B KRW inheritance, this saves millions. Late filing incurs penalty taxes (20%, or 40% for fraud) plus daily interest.
While market value is the principle for inheritance/gift tax, officially assessed land prices are often lower than market value. Professional appraisal can establish appropriate valuations for properties without recent transactions, potentially aiding in tax optimization.
When tax exceeds 20M KRW, installment payment (up to 5 years, 20 years for family business succession) is available. Payment in kind using real estate is also possible when cash is insufficient. Note: installment payments accrue annual interest under Korean tax law.
Inheritance tax is levied on property transferred upon death, based on the decedent's total estate. Gift tax is levied on gratuitous transfers during lifetime, based on the recipient. Both use the same Korean tax brackets but differ in deductions. Inheritance tax has broader deductions (lump-sum 500M, spouse deduction, etc.) while gift tax uses relationship-based deductions. Generally, inheritance tax has lower effective rates due to wider deductions.
Yes, gift tax deductions are calculated on a 10-year cumulative basis from the same donor (lineal ascendants are grouped together). After 10 years, the limit resets. For example, if a parent gifts 50M KRW and waits 10 years to gift another 50M, both are within the tax-free limit. Note: father and mother are grouped as the same lineal ascendant group under Korean tax law.
Gifts to heirs within 10 years before death are added to the inheritance tax base. Gifts to non-heirs within 5 years are added. Therefore, pre-gift tax planning should ideally begin at least 10 years in advance. Gift tax already paid is credited against inheritance tax (previously paid tax credit), so there is no double taxation.
Lump-sum deduction is a flat 500M KRW. Individual deduction combines basic deduction (200M) + personal deductions (children, minors, disabled, elderly). In most cases lump-sum is better, but individual can be larger with disabled heirs or multiple minor children. This calculator automatically compares both options.
Spouse inheritance deduction ranges from 500M to 3B KRW based on the amount actually inherited (within legal share). Estate division must be completed within the 6-month filing period. While maximizing spouse deduction greatly reduces tax, consider the secondary inheritance tax when the surviving spouse passes. Legal marriage registration is required.
Inheritance tax: 6 months from death. Gift tax: 3 months from the end of the month of the gift. Timely filing earns 3% credit. Late filing incurs non-filing penalty (20%, 40% for fraud) plus 0.022% daily late payment penalty. Overseas residents get 9-month inheritance tax deadline.
Beyond gift tax, real estate gifts incur acquisition tax (3.5% with exceptions), registration tax, legal fees, and appraisal costs. Total additional costs can be 7-15% of property value. If the gifted property is sold within 5 years, carryover taxation applies, increasing capital gains tax burden under Korean tax law.
상속세는 피상속인(사망자)의 재산이 상속인에게 이전될 때 부과되는 세금으로, 피상속인의 전체 상속재산을 기준으로 과세합니다. 반면 증여세는 살아있는 증여자가 수증자에게 재산을 무상으로 이전할 때 부과되며, 수증자 기준으로 과세합니다. 두 세금 모두 동일한 세율 구간(10~50%)을 적용하지만, 공제 항목과 납세 의무자가 다릅니다. 상속세는 상속인이 연대하여 납세 의무를 지고, 증여세는 수증자가 납부합니다. 일반적으로 상속세는 배우자공제, 일괄공제 등 다양한 공제 항목 덕분에 실효세율이 낮은 경우가 많습니다.
상속세·증여세 세율은 과세표준에 따라 10%에서 50%까지 5단계 누진세율이 적용됩니다. 1억원 이하 10%, 1억 초과~5억 이하 20%(누진공제 1천만원), 5억 초과~10억 이하 30%(누진공제 6천만원), 10억 초과~30억 이하 40%(누진공제 1억6천만원), 30억 초과 50%(누진공제 4억6천만원)입니다. 산출세액은 과세표준에 세율을 곱한 후 누진공제액을 차감하여 계산합니다. 예를 들어 과세표준 3억원이라면 3억×30%-6천만원=3천만원이 산출세액이 됩니다. 신고기한 내 신고 시 산출세액의 3%를 추가로 공제받을 수 있습니다.
효과적인 절세를 위해서는 증여세 공제 한도를 활용한 사전 증여 계획이 중요합니다. 배우자에게는 10년마다 6억원, 성인 자녀에게는 5천만원, 미성년 자녀에게는 2천만원까지 증여세 없이 이전할 수 있습니다. 이를 10년 주기로 반복하면 오랜 기간에 걸쳐 상당한 재산을 절세하며 이전할 수 있습니다. 다만 상속 개시일 전 10년 이내 상속인에게 증여한 재산은 상속세 과세가액에 합산되므로, 최소 10년 이전부터 계획적으로 시작하는 것이 효과적입니다. 또한 상속 시에는 일괄공제(5억)와 배우자공제(최대 30억)를 최대한 활용하여 세 부담을 줄이세요.
