GoI has introduced an alternate model of NPS with effect from 1st April 2010 so as to provide financial security to various economically disadvantaged groups which consist of poor people usually coming from low income strata and from a lower educational background. This alternate model of NPS is known as NPS-Lite having relatively low cost structure compared to government sector and all citizens of India. The self help groups (Aggregators), Government (Central and/or State) co-sponsored schemes (GCS), government welfare and affinity groups are covered under NPS-Lite. Subscribers of NPS-Lite in the age group of 18 to 60 can join NPS-Lite through Aggregator and contribute till the age of 60.
