The Qualified Invoice System (Tekikaku Seikyu Hakko Houshiki) was introduced on October 1, 2023, and represents a significant overhaul of Japan's consumption tax system. The system's most critical feature is that businesses must retain qualified invoices to claim consumption tax deductions.

If you have life insurance in Japan, you may be eligible for up to ¥120,000 in annual income deductions (seimei hoken-ryō kōjo). This translates to significant savings on both income and residence taxes. Yet many people don't claim this deduction. Proper application often results in tax refunds or reductions worth tens of thousands of yen.
