Financial planning in Japan involves navigating complex social security, pension, and inheritance tax systems. A critical component is the transition from old-age to survivor pensions. Regarding taxation, gift tax regulations distinguish between necessary living expenses and taxable gifts. For the period starting January 1, 2024, the period for adding gifts made under the calendar year taxation system back to the taxable estate is being phased in from three years to seven years. Inheritance tax planning is further complicated by rules regarding residential land. A special provision allows up to an 80% reduction in the taxable value of small-scale residential land, though eligibility depends on the heir's relationship to the deceased. ~~For example, spouses are generally exempt from residency requirements,~~ Spouses may qualify for significant exemptions, while ~~non-cohabiting relatives,~~ siblings or ~~‘homeless children’ (ienaki-ko), must meet strict criteria regarding previous residency~~ nieces and nephews may face a 20% tax surcharge. The tax liability also depends on the ~~deceased’s marital status.~~ basic deduction, calculated as 30 million yen plus 6 million yen multiplied by the number of statutory heirs. High tax rates on illiquid assets have led to extreme cases of distress, including a reported instance where an elderly couple committed suicide due to pressure to pay over 200 million yen in inheritance taxes on real estate they could not liquidate. Retirement planning faces challenges from pension ~~inadequacy. Data indicates monthly deficits for elderly households, with married couples seeing shortfalls of approximately 42,000 yen. To mitigate this,~~ inadequacy and shifting employment structures. While the ~~National Pension Service offers optional enrollment~~ deferred receipt system allows individuals to increase monthly pensions by 0.7% for ~~those aged 60~~ each month delayed (up to ~~65.~~ 84% by age 75), it requires living without income during the deferral period. Additionally, ~~seniors may utilize ‘leaseback’ or ‘reverse mortgages’~~ 69.0% of companies offering retirement benefits provide only lump-sum payments rather than pension-based systems.
