National Pension: Flat-Rate Tier and Exemptions
The Universal Tier
The national pension provides a flat-rate base pension for residents. Candidates must know who is insured, how categories work, and how exemptions and deferrals affect entitlement.
Concepts You Must Master
- Insured categories: the classification of insured persons and how status changes are reported.
- Contribution and exemption: contribution exemptions for low income and deferral for students, and how exemption periods affect the benefit calculation.
- Benefit types: old-age, disability, and survivors' benefits under the flat-rate tier.
- Voluntary participation: rules allowing continued or voluntary coverage.
- Coordination with the employees' tier: the flat-rate tier is the base, and the earnings-related tier is added for employees.
Traps to Watch
The common error is assuming an exempted period counts fully toward benefits. Exemption and deferral affect the calculation. Another trap is confusing a status change with a loss of entitlement.
Worked Example
A low-income insured person is granted a contribution exemption for several months. Those months are not treated identically to fully paid months in the benefit calculation. Rule of thumb: exempt ≠ paid; check the effect on the formula.
Study Tip
Chart the insured categories and the events that move a person between them.
