Step 2 Demand for pre-auction Tax Accounting risk analysis among auction participants

Problem

As National Tax Service delinquent property auctions gain attention, more individual investors are entering public auctions for Real Estate and movable assets. However, they fail to assess tax and legal risks in advance — acquisition tax, capital gains tax, VAT implications, conditions for releasing delinquency liens, and eviction costs — resulting in unexpected post-purchase costs reaching 10-30% of the property value. Individual Tax Accounting consultations cost $150-375 (200,000-500,000 KRW) Per Transaction.

Solution

Enter property details from OnBid (the public auction Platform), and the system automatically calculates acquisition tax rates, capital gains tax scenarios, and VAT applicability by asset type (Real Estate/vehicles/precious metals, etc.). It provides a checklist covering lien release conditions, eviction difficulty, and hidden costs, then simulates the actual investment return.

Target: Individual auction/public sale investors with capital of $7,500-$75,000 (10M-100M KRW), Real Estate micro-investors aged 30-50

Revenue Model: Per Transaction analysis at $7.50 (9,900 KRW), Monthly Subscription at $22/month (29,000 KRW) for unlimited analyses. Tax Accounting professional referral fee of $22.50 (30,000 KRW) Per Transaction
