Derivation Chain

Step 1 EITC maximum 7.2M KRW (~$5,400)
→
Step 2 Demand for eligibility verification among potential recipients

Problem

Workers and Self-employed individuals earning under 22M KRW/year (~$16,500) must navigate HomeTax to check their Earned Income Tax Credit (EITC) eligibility by cross-referencing complex income and asset criteria. The combinations of household type (single/single-earner/dual-earner), total assets, dependent conditions, and other factors are so complex that over 30% of eligible recipients never apply, and many miss the annual application window entirely.

Solution

A simple 5-step questionnaire (income, household type, assets, dependents, employment type) instantly calculates EITC and Child Tax Credit eligibility along with estimated payment amounts. The system provides application period alerts, required document checklists, direct links to the HomeTax application page, and automatically reflects any criteria changes for the current year.

Target: Workers, daily laborers, and Small Business Owners earning under 22M KRW/year (~$16,500), ages 20-60
Revenue Model: Basic diagnosis free + ad revenue; Premium (auto-generated documents + application agent referral) at 9,900 KRW per use (~$7.40)
Ecosystem Role: Consumer
MVP Estimate: 2_weeks
