Step 2 Lack of verification for tax and pension agent services

Step 3 Form rejections due to ignorance of legal requirements when drafting power of attorney

Problem

When employees aged 55-60 try to delegate HomeTax (national tax portal) and National Pension Service tasks to tax accountants or judicial scriveners before/after retirement, each agency requires different power of attorney forms with specific mandatory fields (scope of delegation, validity period, seal/signature requirements). On average, submissions are rejected 2-3 times. Each rejection costs half a day for re-visits, and incorrect delegation scope settings can give tax accountants excessive access or prevent them from performing necessary tasks.

Solution

Users select the agency (HomeTax/National Pension/National Health Insurance/Government24) and tasks to delegate on the web, and the system auto-fills the latest power of attorney form for that agency with real-time validation of mandatory fields. Risk levels by delegation scope (view-only/filing-enabled/refund-collection) are visualized to prevent excessive delegation, and completed forms can be downloaded as PDF.

Target: Office workers aged 55-62 approaching retirement, first-time delegators with no prior experience using tax accountants or judicial scriveners, household heads managing administrative tasks for spouses as well
