During 2005, banks were losing key investments due to thinning popularity of fixed deposits due to frequent reduction in interest rates.  The fixed deposits which were giving interest rates up to 12-14% or more some 5-10 years ago, had slumped down to about 7-9 %. On the other side, with the opening up of insurance sector & growing popularity of mutual funds in India, many new companies smell the big opportunity to trap these dissatisfied banking customers by offering some new & vibrant options.
Banker’s association started lobbying for Government support in this scenario. Convinced with their position the Indian government announced in 2006 vide notification no. 203/2006 dated 28-07-2006 that, bank fixed deposits booked by an individual/HUF for 5 years and up to Rs. One Lac or Rs. 100,000/- will be eligible for exemption under section 80C of Income Tax Act,1961.
This is the same section where we take exemption for life insurance policies, Mutual Funds, etc with a generally higher rate of return. However, as soon as the announcement from income tax department came, fixed deposit regain the lost ground with an effective return of about 11-13 %     [for the highest tax bracket].
But this announcement comes with many terms & conditions & without complying of those, one can not get this exemption. For a common person , this provision means : FD of 5 years will be tax saving instrument. But, in actual terms, there are lot more to adhere for getting the IT benefits. The main conditions are highlighted hereunder :

1.      Fixed Deposit for Above 5 Years

 

The one restriction on choosing term deposit is, it should be minimum of five years. According to the section 80c
“The maturity period of a term deposit receipt of any denomination shall be five years commencing from the date of the receipt”.
