The General Provident Fund (Central Services) Rules 1960 outlines the eligibility and subscription process for India's general provident fund for government employees. It states that temporary government servants after 1 year of continuous service, re-employed pensioners (excluding those eligible for the Contributory Provident Fund), and all permanent government servants can subscribe. Subscribers must make a nomination and contribute monthly 6-100% of their emoluments, with interest currently at 12% compounded annually. The rules allow advances and withdrawals for specific purposes.
