Problem

A 58-year-old owner of two properties faces annual changes in capital gains tax, comprehensive real estate tax, and inheritance tax laws, but determining which changes actually affect their situation requires a Tax Accounting consultation costing 100,000–300,000 KRW (~$75–225) per session. Reading tax reform news doesn't help them judge 'does this apply to me?' — leading to unnecessary anxiety, or worse, missing critical changes that result in millions of won in tax differences.

Solution

Users register their number of properties, acquisition dates, approximate market values, and family composition (spouse, number of children) on the web. When tax laws change, the system auto-generates a summary of 'how this change impacts your situation' and sends it via email. Example: '2026 capital gains tax long-term holding special deduction change → estimated 3.5 million KRW (~$2,625) tax increase if you sell Apartment A.'

Target: Ages 50–65, owners of 1–3 properties, asset holders planning to sell, gift, or bequeath within the next 5 years
Revenue Model: 1 property free; 2+ properties + gift/inheritance simulation at 29,900 KRW (~$22) Annual Subscription
Ecosystem Role: Regulation
