Step 3 Integrated calendar for first-year taxes, social insurance, and filing deadlines

Problem

When a 52-year-old retiree transitions to freelancing, over 10 administrative events hit in the first year — business registration, VAT filing, comprehensive income tax filing, National Health Insurance conversion, National Pension voluntary enrollment, and more. No single service consolidates each event's deadline, required documents, and filing method. Missing a VAT filing incurs a 20% penalty surcharge; delaying health insurance conversion triggers retroactive premium charges.

Solution

Users enter their business registration date and industry on the web, and the service generates a month-by-month calendar of all tax, insurance, and filing deadlines for the first 12 months. Each event shows (1) deadline, (2) required documents, (3) filing instructions (with direct links to HomeTax/NHI portals), and (4) penalties for missing it.

Target: People aged 50-58 who transitioned to Freelancer or Solo Entrepreneur status less than 1 year ago after retirement
Revenue Model: Basic calendar free. Step-by-step HomeTax filing guide per event + email reminders at $3.00/Monthly Subscription.
Ecosystem Role: Regulation
MVP Estimate: 2_weeks
