The enactment of the NSSF Act of 2013 marked a significant milestone for the pensions industry in Kenya. At a time when the need for financial security in retirement was becoming increasingly apparent, the Act provided a much-needed overhaul of the existing system, which had long been criticized for its inadequacies.

Prior to the 2013 reforms, the National Social Security Fund (NSSF) was primarily a provident fund, offering lump sum payments upon retirement, disability, or death. While this system provided some level of support, it fell short of ensuring long-term financial security for retirees. The NSSF Act of 2013 transformed the fund into a social insurance pension scheme, with the promise of offering regular income to retirees for the rest of their lives. This shift was not only timely but necessary, as it aligned the NSSF with international best practices in pension provision.

One of the most significant changes brought about by the Act was the introduction of mandatory contributions for both employees and employers. This move was crucial in creating a sustainable source of funding for the pension scheme, ensuring that retirees would receive benefits that were both predictable and adequate. By mandating contributions based on a percentage of an employee's earnings, the Act also introduced a level of equity into the system. Higher earners would contribute more and, in turn, receive benefits that were proportionate to their contributions. This progressive approach helped to address the disparities that existed under the previous system, where contributions were flat-rate and did not reflect the varying levels of income among workers.

The Act also introduced a two-tier structure, with a universal pension for all workers and the option for higher earners to contribute more for increased benefits. This encouraged a culture of savings and financial responsibility.

In addition, the Act broadened the scope of the NSSF, extending coverage to the informal sector, which represents a significant portion of Kenya's workforce. Prior to the Act, workers in the informal sector were largely excluded from formal pension arrangements, leaving them vulnerable in old age. By making provisions for this group, the NSSF Act of 2013 took an important step towards achieving universal pension coverage, ensuring that all Kenyans, regardless of their employment status, could look forward to a secure retirement.
