Claiming early or deferring
Instead of the standard age of 65, you may claim from 60 years (with a monthly reduction) or defer to as late as age 75 (with a monthly increase).
Claiming early
You may elect to start receiving the pension any month from 60 years up to (but not including) 65 years (National Pension Act 附則 art. 9-2). The same condition applies as for the ordinary route: your paid and exempted insurance periods must add up to at least 10 years.
For each month you claim early, the pension is reduced by 0.4% (Enforcement Order art. 12). No provision was found stating a ceiling on the total reduction.
No provision was found restoring the unreduced rate once fixed at your claiming date, so this reduction appears to continue for as long as the pension is paid. A rule resetting the reduction at a set later age, of the kind some neighbouring systems have, was not found here.
Deferring
If you have not claimed by age 66, you may apply to defer claiming up to age 75. A 2020 reform raised this ceiling from the previous age 70 (附則 art. 28).
For each month from 65 years to the month before your deferral application, the pension is increased by 0.7%, capped at 120 months (10 years) — Enforcement Order art. 4-5. At the full 10-year deferral, the increase reaches a maximum of 84%.
