The National Pension system covers people from 25 to 65 years old who do not receive benefits as military personnel, government employees, or teachers. The system was originally intended to cover housewives, unemployed workers, and farmers, but the Legislative Yuan excluded the 800,000 receiving Farmers Insurance benefits from the National Pension system. That reduced to 3.5 million the number eligible for coverage under the National Pension system.
至於範圍更廣的國民年金，則是針對 25 到 65 歲，未參加軍公教及勞保等社會保險的民眾，原本對象包括家庭主婦、未就業勞工、農民等，但立法院最後通過修法，將現有農保 80 萬人與國民年金脫鉤，國民年金適用範圍縮小到 350 萬人。
