Bitcoin holders in their 50s cannot determine how much tax they or their children would owe if they pass away or transfer assets during sharp market downturns or rallies. The valuation standard for virtual asset inheritance and gifting (average price over the 2 months before/after death) differs from stocks, and the National Tax Service's guidance is unhelpful, leading people to spend 500,000-1,000,000 KRW (approx. $375-$750) on tax accountant consultations or simply ignore the issue. Combined with the virtual asset taxation system effective from 2025, the risk of penalty surcharges from incorrect filing is significant.
Solution
Users enter their held coin types, quantities, and acquisition costs on the web, and the service (1) automatically calculates estimated inheritance and gift taxes based on current market prices, (2) provides optimal gifting timing simulations (at tax bracket boundaries), and (3) generates a pre-filled PDF matching the National Tax Service filing form. Differentiator: There is no virtual asset-specific inheritance and gifting simulator in Korea — only stock and real estate tools exist.
Target: Ages 45-60, holding 10 million KRW (approx. $7,500) or more in Bitcoin or Ethereum, household heads with adult children, seeking preliminary review before tax accountant consultation
Revenue Model: Basic simulation free; detailed report (gifting split optimization + filing draft) PDF at 5,000 KRW (approx. $3.75) per transaction. Future revenue from tax accountant referral fees.
