Korean Capital Gains Scenario Comparator

LIVE

4 scenarios compared: sell now, 1y later, 10y later, or gift. Korean capital gains tax with long-hold discount and 2026 multi-home surcharge.

About this tool

Korean Capital Gains Scenario Comparator charts after-tax outcomes for four scenarios β€” sell now, sell in 1 yr, sell in 10 yr, gift to child β€” on one screen. From acquisition / sale price / costs, holding & residency, 1-house status, regulated zone, multi-house status, expected appreciation, and gift recipient, the tool surfaces per-scenario capital-gains tax (national + 10% local), gift tax, and the resulting after-tax proceeds or child-side asset value. It auto-applies the post-2026-05-09 multi-house surcharge (regulated +20% / +30%p), the 1-house β‚©1.2B non-tax line, the 4%/yr residency + 4%/yr holding = up to 80% long-hold deduction (Table 2), and the carryover-tax rule.

Frequently asked

Q. Why tax even with 1-house status?
A. Only the portion above β‚©1.2B is taxable β€” e.g., a β‚©1.5B sale taxes 20% of the value. Requires 2 years of holding and household-level 1-house status.
Q. How is long-hold deduction computed?
A. For 1-house with residency: 4%/yr residency + 4%/yr holding = up to 80% over 10 years. Other homes: 2%/yr holding, up to 30% over 15 years.
Q. Who is hit by 2026-05-09 surcharge?
A. Post-deferral, regulated-zone 2-home owners get +20%p, 3+-home owners +30%p. Unregulated zones are not affected.
Q. What counts as cost?
A. Acquisition / registration tax, legal fees, broker commission, capital-improvement renovation, registration costs β€” all require receipts / VAT invoices.
Q. File with this output?
A. No β€” early planning only. File via Hometax or a CPA after detailed review.
