How it works

  • The life insurance premium deduction is calculated from the annual premiums (paid from January to December) for three categories — general life insurance, nursing-care/medical insurance, and personal pension insurance — giving separate deductions for income tax and resident tax.
  • The new system covers contracts concluded on or after 1 January 2012; the old system covers contracts concluded on or before 31 December 2011. The nursing-care/medical category exists only under the new system.
  • Under the new system, the income-tax deduction is: annual premium up to 20,000 yen = full amount; 20,001–40,000 = ÷2 + 10,000; 40,001–80,000 = ÷4 + 20,000; over 80,000 = a flat 40,000 (per-category cap 40,000). The resident-tax deduction uses a separate formula with a per-category cap of 28,000 yen.
  • Under the old system, the income-tax deduction is: up to 25,000 yen = full amount; 25,001–50,000 = ÷2 + 12,500; 50,001–100,000 = ÷4 + 25,000; over 100,000 = a flat 50,000 (per-category cap 50,000). The resident-tax per-category cap is 35,000 yen.
  • When a category has both new and old contracts, the larger of the old-only deduction and the combined new+old amount (capped at the new-system per-category limit) is used.
  • The combined deduction across the three categories is capped at 120,000 yen for income tax and 70,000 yen for resident tax. Fractions of a yen in the deduction are rounded up.
  • This tool is an estimate based on the standard formulas. Category eligibility (for example, personal pension insurance requires a qualifying tax rider) follows the deduction certificate issued by your insurer. Actual deductions and tax depend on your other deductions and rates; confirm official figures with your insurer, tax office, and local government.
