Features of Tax-Free Bonds

Below we have mentioned some important characteristics of Tax-free bonds which will help you understand more about them.


This bonds are one of the safest investment options available in the market to investors because of their backing by the government. Most of these bonds are rated as ‘AAA’ because of the guarantee from the government.  So, there are very low or negligible risks associated with the non-payment or default by these bonds.


There is no upper limit on the investments in these bonds.

These bonds offer a slightly higher interest rate to retail investors, i.e individual and Hindu undivided family (HUFs). However, the limit to achieve this higher interest rate is a maximum investment of Rs. 10 Lakhs.

In case an investor makes an investment of above Rs. 10 Lakhs, he is considered a high net-worth individual and does not get the higher interest rate applicable for retail investors.


Tax-free bonds offer coupon rates of 7-9% depending upon different issuers and tenures, these are the annual interest payments that are made to investors. The rate of return offered to retail investors (investments under Rs. 10 lakhs) is generally slightly higher.

The interest is generally paid on an annual basis. There is an option of opting for half-yearly payment.  However, this option comes with a hit of approximately 0.15% in the interest rate. Investors also have the option to opt for cumulative payments. In this case the interest is added to the principal amount, and the complete amount is paid out at the time of maturity. 

However, if we talk about returns on bonds, then the Yield-to-Maturity or YTM of these bonds is the true indicator. Given the higher coupon rates, the YTM also turns out to be slightly higher for retail investors.

The YTM on these tax-free bonds works out to be higher than the after-tax return of other fixed-income instruments (depending upon the purchase price of bonds i.e at discount or premium)


Tax-free bonds are normally listed on exchanges such as the NSE, and an investor can buy or sell these bonds from the exchange. However, as most investors purchase these bonds for long term investments, trading can generally be fairly illiquid on the exchanges. Even though you may find an exit, volumes and prices can be a problem.


The most important feature of these bonds is the fact that the interest earned from these bonds is tax-free. For taxation purposes it does not matter if the interest payments are annual, half-yearly or cumulative. Under section 10 of the Income Tax Interest payments on Tax-Free bonds are exempted from tax and the investors are not required to pay any tax on this income.

However, any capital gains from selling the bonds within one year from purchase of the bond is taxable at the investor’s applicable slab rate. In the case the tax-free bonds are sold after one year, any capital gains arising will be taxed at 10% LTCG without indexation or at the rate of 20% with indexation benefit.


Tax-free bonds have been issued with long maturity tenures. The general maturities are 10,15 and 20 years. These bonds have a lock-in and investors cannot withdraw them before the expiry.

Benefits of Tax-Free Bonds

  • As mentioned earlier, one of the top benefits of investing in Tax-Free bonds is the nature of tax treatment on the interest earned from these bonds. The interest earned on these bonds is completely tax-free under section 10 (15) (iv) (h) of the Income Tax Act, 1961.
  • These bonds also provide post-tax returns greater than Bank FDs and several other risk free or low risk bonds. this bonds issued by the government-backed entities have annual coupon rates ranging between 7-9%. At current prices, these bonds have Yield to Maturity (YTM) of around 5-6%. If one is to adjust this for tax (assuming a 30% tax bracket), the pre-tax bond yields compute to approximately 7.2% to 8.5%. This is greater than the interest from other fixed income instruments such as Bank FDs and other bonds after taxation. Bank FDs are currently offering between 5.5% and 7% on a pre-tax basis.

The yield to maturity (YTM) is the rate of return for a bond assuming that the investor holds the asset until its maturity date.

  • Tax-free bonds are suitable for investors in higher tax brackets as they can earn more from these bonds as opposed to after paying 30% tax on FDs and getting a lower post-tax return.

For example- A 15-year bond issued by the National Highways Authority of India in 2015 with a par value of 1000 and a coupon rate of 8.30% is trading on NSE at the price of ₹1224. The YTM of the bond comes out to be 5.25% and assuming a 30% tax bracket, this is as good as a Fixed Deposit fetching 7.5% rate.

  • It could be a very good option for investors looking for a regular interest income. For investors such as retired individuals, the interest from these bonds can be very helpful in the absence of an active source of income.
  • Tax-Free bonds are issued for maturities of 10, 15 or 20 years. This is beneficial for investors who are worried about interest rates falling in the future, as the coupon payments get locked-in for a long period, i.e. the tenure of the bond itself.
