Overview of the 2026 Pension Reforms
Japan's pension reform act, enacted on June 13, 2025, brings major changes to both public pensions and private pensions (iDeCo and corporate DC plans) in 2026. The reforms aim to reduce pension penalties for working seniors and expand retirement savings options for the working population.
Working Pension Threshold Increase (April 2026)
What Is the Working Pension System?
The working old-age pension (zaisyoku rourei nenkin) reduces pension benefits for people aged 65+ who work while enrolled in employees' pension insurance. When the combined monthly income (salary + pension) exceeds a set threshold, half the excess is withheld.
Key Changes
| Item | Before Reform | After Reform (April 2026) |
|---|---|---|
| Suspension threshold | ¥510,000/month | ¥620,000/month |
| Increase | — | +¥110,000 |
Calculation Example
For someone earning ¥450,000/month with a ¥100,000/month pension (total: ¥550,000):
- Before: (¥550,000 − ¥510,000) ÷ 2 = ¥20,000 withheld
- After: Below ¥620,000 → No reduction (full pension)
Approximately 200,000 people are expected to receive their full pension as a result.
iDeCo Expansion
Phase 1: Matching Contribution Reform (April 2026)
The rule requiring employee matching contributions to not exceed employer contributions in corporate DC plans is abolished, giving workers more flexibility.
Phase 2: Age and Contribution Limit Increases (December 2026)
| Category | Current | Revised |
|---|---|---|
| Eligibility age | Under 65 | Under 70 |
| Limit (no corporate pension) | ¥23,000/month | ¥62,000/month |
| Limit (with corporate pension) | ¥55,000/month | ¥62,000/month |
| Limit (self-employed) | ¥68,000/month | ¥75,000/month |
Employees without corporate pensions see the biggest benefit: annual contribution capacity grows from ¥276,000 to ¥744,000 — roughly a 2.7x increase.
Tax Savings
An employee earning ¥5 million/year contributing ¥62,000/month can save approximately ¥149,000/year in income and resident taxes.
Combined Impact on Post-60 Financial Planning
| Reform | Benefit | Effective Date |
|---|---|---|
| Higher pension threshold | Work without pension cuts | April 2026 |
| Matching contribution freedom | Flexible corporate DC top-ups | April 2026 |
| iDeCo age extension | Contribute until age 70 | December 2026 |
| Higher iDeCo limits | Build larger tax-free retirement savings | December 2026 |
Practical Steps
For Workers Aged 65+
- Check your combined monthly income + pension against the new ¥620,000 threshold
- Use Nenkin Net to verify your projected pension amount
For Current Workers
- Confirm whether your employer offers a corporate DC plan
- Consider increasing matching contributions starting April 2026
- Plan iDeCo contribution increases carefully, balancing with living expenses
For Self-Employed Workers
- Review coordination with National Pension Fund and supplementary pension contributions
- Adjust contribution plans to reflect the new ¥75,000 monthly limit
Note that the working pension threshold change applies automatically, but iDeCo changes require personal action. Consult your pension office or financial institution before the reforms take effect.
