Korean Capital Gains Scenario Comparator
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?

- 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.
