Section 80C comprises certain instruments, investing in which can save you tax up to Rs. 45,000 per annum; depending on your tax slab. These instruments include equity linked saving scheme (ELSS), term insurance plans, unit-linked insurance plans (ULIPs), public provident fund (PPF), bank fixed deposits (FDs), and National Saving Certificates (NSCs). A maximum of Rs. 1.5 lakh invested in all these instruments together is eligible as a deduction from your gross total income or taxable income. Also, an additional deduction, up to Rs. 50,000, against the amount invested towards new pension scheme (NPS) is available under the section. However, to make the best use of these instruments for claiming deduction under the Income Tax Act, it is essential to know these instruments in detail.
