Section 80C limit is exhausted, how can I still save more tax?

I am 33 years old and work for a large multi-national company. Investors can choose from seven pension fund managers and decide their own asset mix. While the NPS is a good way to save for retirement and reduce tax, keep in mind certain features of the scheme. The silver lining is that one’s income comes down after retirement so the pension does not increase the tax liability too much. They can also shift from one pension fund manager to another without incurring any tax incidence.
