Your US Resident Parent
Had Korean Assets?
A 9-Month Roadmap for US-Based Heirs.

Approximately ₩960 million (~$685K) at ~32% effective rate. Calculation: ₩3B assets − ₩200M basic deduction = ₩2.8B tax base → progressive rate 40% − ₩160M progressive credit = ~₩960M.

This is the non-resident penalty: no ₩500M lump-sum deduction, no spousal deduction, no personal deductions. The same estate would owe only ₩2-3 hundred million if the decedent had been a Korean resident (with spouse + 2 children).

For your specific case, use the free calculator above with your actual asset/heir details for instant estimate.

Use Korea's "Inheritance Asset Search Service" (상속재산조회). Apply via city office or Government24 portal for consolidated lookup as of date of death:

• Financial assets: deposits, insurance, securities, pensions (Financial Supervisory Service)
• Real estate: registered property (Ministry of Land)
• Unpaid taxes: national/local tax arrears
• Vehicles: registered cars (Ministry of Land)
• National pension (if applicable)

Our operator can handle this lookup on your behalf with power of attorney. Recommended within 3 months of death (later possible with additional documentation).

Principle is fair market value (FMV at date of death). 공시가격 is only fallback. Recommended valuation by property type:

• Apartments: Comparable sales of same-size unit within 6 months before or after the date of death (FMV-equivalent). Or certified appraisal.
• Land / detached homes: Certified appraisal recommended (₩500K-1.5M)
• Commercial / office: Income capitalization + appraisal

Warning: In high-value areas (Gangnam, Songpa, etc.) where market price is 1.5-2x the 공시가격, filing only with 공시가격 invites tax authority reassessment → additional tax + penalty. Our operator advises on valuation strategy.

No Korea visit needed. Our operator handles the entire Korean-side process with power of attorney:

• Asset search and valuation
• Korean inheritance tax return preparation and filing
• Tax authority correspondence and audit response
• Korean real estate title transfer (상속등기)
• Korean bank account settlement

Documents you prepare in the US:

• Death certificate + English translation (apostilled)
• Family relationship documents (Korean side via our operator)
• Power of attorney (Korean Consulate notarization, ~$40)
• Signature/seal certification (Consulate)

Typical processing time: 3-6 months, well within the 9-month deadline.

Payment method: Wire transfer USD to Korean bank account (heir's name or operator's trust account). Foreign exchange filing required for USD 50K+ (operator handles this). Wire fee ~0.5-1%.

Installment options:

• 2-installment (분납): 50% by filing deadline + 50% within 2 months. No interest. Automatic.
• Long-term installment (연부연납): Up to 10 years (when real estate is 50%+ of estate). 5- or 10-year option. Korean government surcharge (3.1% in 2026). Collateral required (real estate, deposits, bank guarantee).

When cash is tight, long-term installment is often much better than forced property sale. Operator advises on optimal payment strategy.

Heirs Agreement (상속재산분할협의서) allows free division (can differ from legal default shares). Process:

1. Family discussion via Zoom on division ratio and method
2. Operator drafts the agreement
3. Korea-resident heirs: seal-stamp with registered seal (인감)
4. US-resident heirs: signature authentication at Korean Consulate (~$40, 2-week wait)
5. Completed agreement submitted to tax authority, registry, banks

Caution: Division ratio affects spousal deduction (capped at legal share). Operator provides tax-optimized division simulations.

If dispute arises: Family court mediation (if unresolved, default to legal shares).

Full release typically takes 3-6 months (after Korean inheritance tax filing/payment + property transfer registration). Phased access:

• Emergency withdrawal (limited): With funeral expense receipts, banks allow partial withdrawal (₩5-15M depending on bank)
• Balance inquiry: Family relationship cert + death certificate = immediate access
• Transfer/closure: Requires heirs agreement + tax payment certificate + family relationship cert submitted together

Each bank's process varies (KB, Shinhan, Hana, Woori, etc.). Operator handles all banks on behalf of US-based heirs.

유류분 (Legal Reserved Portion): Korean civil law guarantees minimum inheritance share for children and spouse. Half of legal share (one-third for parents).

Example: If father wills "entire estate to eldest son," the second son can sue Korean family court for legal share 1/4 × 1/2 = 1/8 of total estate.

Claim deadline:

• 1 year from knowledge of infringement
• 10 years from inheritance commencement (statute of limitations)

US-based heirs can file too. Korean family court petition (via Consulate-notarized power of attorney). Operator advises on strategy and documents (attorney recommended for litigation).

Prevention: While parent is alive, notarized will (공정증서) + division that respects 유류분 is the best protection.

Yes. File with Korean family court within 3 months of knowledge of inheritance. Two options:

• Full Renunciation (상속포기): Receive nothing, owe nothing. BUT debt passes to next-line heirs (children, then siblings). Entire family up to 4th degree must renounce together to fully shield from debt.
• Limited Acceptance (한정승인): Receive assets, but liability capped at asset value. Public notice procedure required.

If uncertain about assets/debts: Limited Acceptance is safer. Operator runs asset search first to clarify before deciding.

US-based heirs: File via Consulate-notarized power of attorney. 3-month deadline is strict — decide quickly.

Four powerful strategies:

• ① 10-year gifting plan: ₩50M tax-free per adult child per 10 years. With 3 children, that's ₩150M tax-free per decade. Grandchildren have separate limits.
• ② Korean resident status conversion: Increase parent's Korean residence time 5-7 years before death → qualify as Korean resident → ₩500M lump-sum + spousal deduction → ₩500-700M tax savings vs. non-resident. Caution: Last-minute fake residency is challenged.
• ③ Sell Korean real estate before death + distribute: Capital gains tax + gifting > inheritance tax + lump bracket trap.
• ④ Family business inheritance deduction (가업상속공제): For Korean SME shares — up to ₩60 billion deduction (by holding period: 10+ years ₩30B, 20+ years ₩40B, 30+ years ₩60B). Requires successor's 10-year management retention + 80% workforce maintenance.

Illustrative simulation: For Korean parents in their 70s with approximately ₩3B in Korean assets, a 5-year planning simulation may show Korean inheritance tax ranging from ~₩900M (no planning) down to ~₩300M (with planning), depending on asset composition, family structure, and timing.
※ These figures are illustrative simulations by a Korean CPA and do not guarantee results for your specific case. Individual consultation required for actual planning.
