As per the Income Tax Act and further amended Income Tax Department's time to time Notification and amended Section Under Section 80C is given below:-

The total limit under this section is Rs 1 lakh. Included under this heading are many small savings schemeslike NSC, PPF and other pension plans. Payment of life insurance premiums and investment in specified government infrastructure bonds are also eligible for deduction under Section 80C
Most of the Income Taxpayee try to save tax by saving under Section 80C of the Income Tax Act.  However, it is important to know the Section in toto so that one can make best use of the options available for exemption under income tax Act.   One important point to note here is that one can not only save tax by undertaking the specified investments, but some expenditure which you normally incur can also give you the tax exemptions.
Besides these investments, the payments towards the principal amount of your home loan are also eligible for an income deduction. Education expense of children is increasing by the day. Under this section, there is provision that makes payments towards the education fees for childreneligible for an income deduction
Sec 80C of the Income Tax Act is the section that deals with these tax breaks. It states that qualifying investments, up to a maximum of Rs. 1 Lakh, are deductible from your income. This means that your income gets reduced by this investment amount (up to Rs. 1 Lakh), and you end up paying no tax on it at all!
This benefit is available to everyone, irrespective of their income levels. Thus, if you are in the highest tax bracket of 30%, and you invest the full Rs. 1 Lakh, you save tax of Rs. 30,000. Isn’t this great? So, let’s understand the qualifying investments first.
Qualifying Investments
Provident Fund (PF) & Voluntary Provident Fund (VPF)and (PF) is automatically deducted from your salary. Both you and your employer contribute to it. While employer’s contribution is exempt from tax, your contribution (i.e., employee’s contribution) is counted towards section 80C investments. You also have the option to contribute additional amounts through voluntary contributions (VPF). Current rate of interest is 8.5% per annum (p.a.) and is tax-free.
Public Provident Fund (PPF):Among all the assured returns small saving schemes, Public Provident Fund (PPF) is one of the best. Current rate of interest is 8% tax-free and the normal maturity period is 15 years. Minimum amount of contribution is Rs 500 and maximum is Rs 70,000. A point worth noting is that interest rate is assured but not fixed. Interest on PPF  is proposed to increase to 8.60% and Investment Limit is also expected to increase to Rs. 1,00,000/- very soon.
Life Insurance Premiums: Any amount that you pay towards life insurance premium for yourself, your spouse or your children can also be included in Section 80C deduction. Please note that life insurance premium paid by you for your parents (father / mother / both) or your in-laws is not eligible for deduction under section 80C. If you are paying premium for more than one insurance policy, all the premiums can be included. It is not necessary to have the insurance policy from Life Insurance Corporation (LIC) – even insurance bought from private players can be considered here.
Equity Linked Savings Scheme (ELSS): There are some mutual fund (MF) schemes specially created for offering you tax savings, and these are called Equity Linked Savings Scheme, or ELSS. The investments that you make in ELSS are eligible for deduction under Sec 80C.
Home Loan Principal Repayment:The Equated Monthly Installment (EMI) that you pay every month to repay your home loan consists of two components – Principal and Interest.The principal component of the EMI qualifies for deduction under Sec 80C. Even the interest component can save you significant income tax – but that would be under Section 24 of the Income Tax Act. Please read “Income Tax (IT) Benefits of a Home Loan / Housing Loan / Mortgage”, which presents a full analysis of how you can save income tax through a home loan.
Stamp Duty and Registration Charges for a home: The amount you pay as stamp duty when you buy a house, and the amount you pay for the registration of the documents of the house can be claimed as deduction under section 80C in the year of purchase of the house.

National Savings Certificate (NSC): National Savings Certificate (NSC) is a 6-Yr small savings instrument eligible for section 80C tax benefit. Rate of interest is eight per cent compounded half-yearly, i.e., the effective annual rate of interest is 8.16%. If you invest Rs 1,000, it becomes Rs 1601 after six years. The interest accrued every year is liable to tax (i.e., to be included in your taxable income) but the interest is also deemed to be reinvested and thus eligible for section 80C deduction.
Pension Funds – Section 80CCC: This section – Sec 80CCC – stipulates that an investment in pension funds is eligible for deduction from your income. Section 80CCC investment limit is clubbed with the limit of Section 80C – it maeans that the total deduction available for 80CCC and 80C is Rs. 1 Lakh.This also means that your investment in pension funds upto Rs. 1 Lakh can be claimed as deduction u/s 80CCC. However, as mentioned earlier, the total deduction u/s 80C and 80CCC can not exceed Rs. 1 Lakh.
5-Yr bank fixed deposits (FDs): Tax-saving fixed deposits (FDs) of scheduled banks with tenure of 5 years are also entitled for section 80C deduction.
Senior Citizen Savings Scheme 2004 (SCSS): A recent addition to section 80C list, Senior Citizen Savings Scheme (SCSS) is the most lucrative scheme among all the small savings schemes but is meant only for senior citizens. Current rate of interest is 9% per annum payable quarterly. Please note that the interest is payable quarterly instead of compounded quarterly. Thus, unclaimed interest on these deposits won’t earn any further interest. Interest income is chargeable to tax.
5-Yr post office time deposit (POTD) scheme: POTDs are similar to bank fixed deposits. Although available for varying time duration like one year, two year, three year and five year, only 5-Yr post-office time deposit (POTD) – which currently offers 7.5 per cent rate of interest –qualifies for tax saving under section 80C. Effective rate works out to be 7.71% per annum (p.a.) as the rate of interest is compounded quarterly but paid annually. The Interest is entirely taxable.
NABARD rural bonds: There are two types of Bonds issued by NABARD (National Bank for Agriculture and Rural Development): NABARD Rural Bonds and Bhavishya Nirman Bonds (BNB). Out of these two, only NABARD Rural Bonds qualify under section 80C.
Unit linked Insurance Plan : ULIP stands for Unit linked Saving Schemes.
