Problem

When parents aged 50-60 financially support their adult children's weddings, the new 2024 marriage gift tax exemption (additional 100 million KRW / ~$75,000) was introduced, but very few parents understand its relationship with the existing gift tax exemption limit (50 million KRW / ~$37,500 over 10 years), combined limits when both parents gift separately, interaction with prior gifts, or optimal timing for split gifting. They either spend $150-375 on tax accountant consultations, overpay gift taxes by thousands of dollars due to misunderstanding, or face penalty taxes for failure to report.

Solution

Users enter on the web: (1) desired gift amount, (2) number of children, (3) planned wedding date, (4) prior gift history (within 10 years), and (5) whether both parents will gift separately. The system displays a comparison table of 3 split-gifting scenarios that minimize gift tax. Each scenario specifies the tax amount, filing timeline, and required documents, plus provides a step-by-step checklist for filing gift tax returns through HomeTax (Korea's online tax portal).

Target: Parents aged 50-60 with adult children planning to marry within 1-3 years, planning to provide $37,500-$150,000 in wedding financial support
