New Delhi, Aug 4: Finance Minister Nirmala Sitharaman on Tuesday informed the Parliament that the Centre has no proposal to amend or replace the Unified Pension Scheme, which will continue as an optional scheme under the National Pension System. The Unified Pension Scheme came into force on April 1, 2025. In case of the pensioner’s death, eligible family members can receive a family pension equivalent to 60 per cent of the employee’s pension. The Old Pension Scheme (OPS) provided a pension linked to 50 per cent of the last basic pay along with applicable dearness allowance and was fully funded by the government. Under the NPS, retirement income is based on the accumulated corpus and market-linked returns, with contributions from employees and the government.
