Frequently asked questions
What is the iDeCo contribution limit for employees in Japan?
Employees at companies with a corporate pension plan can contribute ¥12,000/month (¥144,000/year). Those without a corporate pension plan can contribute ¥23,000/month (¥276,000/year). Self-employed (第1号被保険者) can contribute up to ¥68,000/month.
Can I withdraw from iDeCo early in Japan?
Generally no. iDeCo funds are locked until age 60 (or 75 if you started after 62). Early withdrawal is not permitted except in cases of terminal illness or incapacity. This is the main drawback versus NISA.
How is iDeCo taxed at withdrawal?
Lump-sum withdrawal is taxed as retirement income (退職所得), which has a generous exemption of ¥800,000 + ¥70,000 × years contributed (for 20+ years). Annuity payments are taxed as public pension income (雑所得) with up to ¥1.1M/year exempt.
