Tax Housing Loan Context
Background context loader for Japan's housing loan tax credit (住宅ローン控除) that Claude auto-loads when users ask about mortgage deductions during tax filing. It pulls eligibility rules, credit limits, and calculation tables from a reference file covering current year rates, special provisions for young families with children, and how the credit interacts with furusato nozei donations. Not something you invoke directly. It's designed to sit in the background so Claude can correctly walk through the eligibility flowchart and handle edge cases like simultaneous purchase and renovation credits without hallucinating the tax law details.
