Compare the settlement after Korean taxes
A settlement between siblings over a parent’s lifetime gift involves more than agreeing on a payment.
The person returning property needs to understand the possible reduction of previously paid gift tax, while the recipient needs to understand the inheritance tax allocated to them.
An overstated refund or missed inheritance filing can leave both sides with a different net position from the one they expected.
This is a worksheet for a tax-reviewed settlement, rather than a new calculation of the underlying forced-heirship shortfall.
It compares gift tax and total family inheritance tax before and after the return, showing recipient net economic receipt only when individual allocations are confirmed.
For the underlying entitlement or shortfall, start with the separate forced-heirship claim calculator and obtain case-specific review.
Functions and supported cases
Separate each result
Review the estimated gift-tax refund, family inheritance-tax change, payer net economic burden and recipient net economic receipt separately.
Compare retained and unapplied gift filing-credit assumptions without treating either as an approval of eligibility.
Dates and records
Check the distinct conditions for a three-month gift-tax later-event claim and a six-month special inheritance claim.
The original inheritance return date is shown separately, and a TXT worksheet preserves the entered figures and results for review.
This English experience uses Korean rules, KRW and the 2026 ordinary-rate model for deaths from 2026-01-02, with Korean resident decedents and heirs.
Additional same-donor gifts requiring aggregation, nonresidency or overseas addresses, generation-skipping surcharges, foreign-tax relief and special business relief are withheld for separate calculation.
The fictional example’s checked confirmation boxes are teaching assumptions and do not verify any real case.
Read the original gift-tax return first
- The original gift value is the amount used for the original gift taxation.
The reversed portion must use that same gift-date valuation basis.
- The receipt value is a separate amount reviewed for inheritance-tax attribution.
For an in-kind return, use the death-date valuation and do not substitute today’s market price.
- The gift deduction is the amount actually applicable to that historical gift.
The default filing credit is the current 3%; verify the historical rate from the original return instead of retroactively applying current law.
- Enter only gift-tax principal actually paid.
Penalties, refund interest and taxes from other gifts must be separated; a mismatch with the modeled original principal withholds the calculation.
The returned ratio is the reversed original gift value divided by the original gift value.
A partial return leaving a gift below the deduction, or a complete return, still requires a fresh application of deductions and progressive brackets.
The refund is therefore not generally a simple percentage of the original payment.
If another gift from the same donor requires 10-year aggregation, select that condition and recalculate the full gift-tax position separately.
Prior gifts and inheritance-credit limits
Inheritance and Gift Tax Act Article 13 adds gifts made to an heir within 10 years before death and gifts made to a non-heir within 5 years.
Non-heir status does not automatically exclude every prior gift.
The model checks the original donee’s status and gift/death dates, including the calendar boundary date.
Exclude this prior gift from original estate assets to avoid counting it twice.
Enter other gifts added to the estate separately.
The net estate-asset component after eligible debts and expenses is floored at zero.
Enter reviewed deductions before and after return, including spouse relief and the Article 24 deduction limit where relevant.
Article 28 uses assessed gift tax, a different concept from gift-tax principal actually paid after filing credit.
Both the overall limit and the heir or legatee’s individual limit must be reviewed.
No Article 28 credit is available when the taxable estate value is at most KRW 500 million.
The tool blocks obvious numerical contradictions but does not itself establish the individual legal credit limit.
Formulas and signs
Estimated gift-tax refundOriginal paid principal minus revised gift tax.
Revised tax applies the brackets to the remaining gift after the historical deduction, then applies the selected filing-credit assumption.
A negative refund means additional gift tax, not money receivable.
Net family tax changeFamily inheritance tax after minus before, minus the gift-tax refund, plus both parties’ confirmed extra cash-settlement taxes.
Positive means more family tax; negative means less.
Legal and registration costs are excluded from this tax-change measure and included separately in the individual net amounts.
Ordinary inheritance and gift tax rates are 10%, 20%, 30%, 40% and 50%, with taxable-base boundaries of KRW 100 million, 500 million, 1 billion and 3 billion.
The calculator reuses the existing pure bracket function and its progressive deductions.
A correct bracket calculation does not establish the legal valuation, deduction or credit treatment.
Step-by-step use
- Enter death and gift dates and the original donee’s heir status.
Distinguish a final judgment, a reviewed judgment-equivalent settlement and a private agreement, recording finality and awareness separately.
- Transfer the original gift value, deduction, filing-credit rate and paid principal from the gift-tax return.
Keep original-gift reversed value separate from the receipt’s inheritance-tax valuation.
- Confirm before/after estate deductions and Article 28 credits to calculate total family inheritance tax.
Enter the recipient’s individual allocated taxes separately when confirmed.
- Enter each party’s external costs and any reviewed extra cash-settlement taxes.
Resolve withheld reasons before interpreting the two filing-credit scenarios and deadline references.
- Save the TXT worksheet with the judgment and payment evidence for consultation.
An increase calls for review of revised or late filing; a decrease calls for review of correction-claim eligibility and its trigger.
Worked example: returning KRW 200 million
Assume an heir received a gift of 600,000,000 KRW on 2019-01-01, claimed a 50,000,000 KRW deduction and paid principal of 101,850,000 KRW.
Death occurred on 2026-01-10, and a tax-reviewed in-kind agreement returns 200,000,000 KRW on both the original-gift and inheritance-receipt valuation bases.
Original estate assets are 1,000,000,000 KRW, deductions before and after are 500,000,000 KRW, and debts and other prior gifts are zero.
Gift tax
Assessed gift tax falls from 105,000,000 to 60,000,000 KRW.
With filing credit retained, revised tax is 58,200,000 KRW and the refund is 43,650,000 KRW.
Without revised filing credit, tax is 60,000,000 KRW and the refund is 41,850,000 KRW.
Inheritance tax
The taxable estate value remains 1,600,000,000 KRW.
With Article 28 credits falling from 105,000,000 to 60,000,000 KRW and inheritance filing credit at 0%, payable inheritance tax rises from 175,000,000 to 220,000,000 KRW, an increase of 45,000,000 KRW.
Net family tax increases by 1,350,000 KRW with retained gift filing credit, or 3,150,000 KRW without it.
With no external costs, payer net economic burden is respectively 156,350,000 or 158,150,000 KRW.
If the recipient’s reviewed tax allocation rises from zero to 30,000,000 KRW, recipient net economic receipt is 170,000,000 KRW.
This differs from deducting the family’s full 45,000,000 KRW inheritance-tax increase from that person’s receipt.
Individual receipt differs from family tax
Korean inheritance tax depends on the estate and available deductions, followed by separate questions of allocation to heirs and legatees and joint payment liability.
An individual recipient can receive a new tax allocation even when the family’s total tax stays unchanged.
Assuming that one person bears every family tax change can therefore misstate the after-tax settlement.
Payer net economic burden = receipt value minus gift-tax refund plus payer costs and payer extra cash-settlement tax.
Recipient net economic receipt = receipt value minus the increase in their allocated tax, minus recipient costs and extra cash-settlement tax.
Without confirmed individual allocations, only recipient net receipt is withheld.
An in-kind property value is not immediately available cash; plan registration costs and liquidity separately.
Three months and six months serve different purposes
Gift-tax later-event claimFramework Act on National Taxes Article 45-2(2)1 provides a three-month reference period from learning of the qualifying later event.
A judgment-equivalent settlement can qualify, but a private agreement is not automatically included.
Keep evidence of both finality and awareness when they differ.
Special inheritance claimInheritance and Gift Tax Act Article 79(1)1 and Enforcement Decree Article 81(2) provide a six-month period from the final-judgment event.
Check the required inheritance filing, determination or reassessment status.
Application to settlements requires separate review, and this is not an extension for filing increased tax.
For finality on 2026-10-30 and awareness on 2026-11-02, the unadjusted three-month end is 2027-02-02 and the six-month end is 2027-04-30.
Excluding the first day and counting calendar months means that the three-month end from 2026-02-28 is 2026-05-31, rather than simply adding three months to the same day number.
The shared holiday list covers 2025–2027; beyond that range only an unadjusted period end is shown.
Check temporary holidays and extensions separately.
The ordinary domestic inheritance return is due six months from the end of the death month; overseas-address cases with a nine-month period are outside this model.
Cash settlement and the 2026 Civil Act amendment
Civil Act Article 1115, amended on 2026-03-17, provides a claim for payment of value within the forced-heirship shortfall and the addition of interest from the claim date.
This tool does not recommend in-kind return as the current legal default or decide transitional application to an individual case.
Property transferred under an older dispute or a separate agreement requires legal review.
Cash settlement can raise issues of capital-gains taxpayer attribution, tax timing and adjustments to transfer value, depending on disposal timing and the return arrangement.
Capital-gains tax is not calculated here.
Extra taxes are included only after both parties’ amounts are confirmed; a zero amount also needs review.
Separate return principal from interest, damages and other transaction payments in the agreement to support the tax analysis.
Sensitivity, practical scenarios and limits
- Sibling negotiations: compare both gift filing-credit assumptions using the same reviewed inputs and identify who pays each cost.
A lower family tax total does not establish a better individual net receipt.
- Value sensitivity: compare the returned original gift value at ±20% with proportionate receipt values.
Deductions, Article 28 credit amounts and extra taxes stay fixed, so this is arithmetic reference only.
Recheck spouse relief, allocation and credit limits whenever the actual amount changes.
- Consultation preparation: gather the gift-tax return, paid-principal evidence, judgment, finality certificate, awareness evidence, valuation support and before/after inheritance-tax calculations.
Submitting a claim does not guarantee approval or immediate payment.
- Excluded scope: the underlying shortfall, entitlement, penalties, refund interest, claim interest and an optimal agreement amount are not calculated.
A withheld amount does not mean a zero liability.
Frequently asked questions
Does a recipient pay gift tax on a forced-heirship settlement?
Property transferred through the exercise of a Korean forced-heirship return claim can require inheritance-tax treatment.
Calling a payment a settlement does not determine its tax category.
Review the claim, ownership and payment evidence, separating principal, interest, damages and proceeds from other transactions.
Is the gift-tax refund proportional to the returned property?
No.
Progressive tax brackets and deductions mean the remaining gift must be recalculated.
Compare the revised principal with the original principal paid.
Do not use this single-gift model when additional same-donor gifts or generation-skipping rules apply.
Is there no additional inheritance tax if the gift was already included?
The taxable estate can stay the same while the available gift-tax credit decreases, increasing inheritance tax payable.
Different original-gift and death-date valuations can also change the taxable estate.
Family tax and each person’s allocated tax must be distinguished.
Does signing a private agreement start a three-month refund period?
The later-event rule in Framework Act on National Taxes Article 45-2(2)1 requires a qualifying event, including a settlement with the effect of a judgment.
A private agreement is not automatically such an event.
Check the original filing status and possible ordinary amended-claim procedures with the tax office.
Can increased inheritance tax wait until six months after judgment?
No.
The special amended-claim period in Inheritance and Gift Tax Act Article 79 is not an extension for filing additional tax.
Revised returns, late returns and claims for correction have different purposes and eligibility requirements.
Review an increase promptly.
Why is there no automatic six-month inheritance date for a settlement?
Enforcement Decree Article 81(2) specifies a final judgment in inheritance-recovery or forced-heirship litigation.
This tool does not assume that a judgment-equivalent settlement automatically qualifies for that special inheritance rule.
Review the gift-tax later-event claim and inheritance special claim separately.
Does the calculator choose the lowest-tax return method?
No.
Civil Act Article 1115, amended March 17, 2026, provides a claim for payment of value.
In-kind return is not presented as the current legal default.
Capital-gains attribution and extra tax on cash settlement are not calculated automatically.
Compare reviewed figures without treating the result as a determination of agreement validity or an optimal settlement.
Does passing a displayed date make every refund impossible?
No.
A displayed date is a reference period for the selected event.
Calendar-month counting and a shared holiday list are used, but temporary holidays, extensions, service and awareness disputes need separate review.
The tool does not decide whether other correction or appeal procedures remain available.
