What are Tax-Free Bonds? Lists, Types and How to Invest

Tax-free bonds are popular fixed-income instruments for conservative investors seeking stable returns and tax-efficient income. These bonds are issued by the government and public sector undertakings to raise funds for infrastructure and development projects.

Under section 10(15) of the Income Tax Act of 1961, the interest earned from this type of bond is exempted from tax. This makes tax-free bonds an attractive investment option for individuals in higher tax brackets.

This article discusses what tax-free bonds are, the list of tax-free bonds, their types, features and the process of investing in them.

What are Tax-Free Bonds?

How Do Tax-Free Bonds Work?

Tax-free bonds function as debt securities through which investors lend money to government-backed institutions for a predetermined period. In return, the issuer pays a fixed bond interest rate at regular intervals, usually annually.

The interest received by investors is exempt from income tax, making the effective return higher than many taxable fixed-income instruments. At maturity, the principal amount invested is returned to the bondholder.

Tax-free bonds are also listed on stock exchanges, allowing investors to buy or sell them before maturity, subject to market conditions and liquidity.

How to invest in Tax-Free Bonds?

Investors can purchase tax-free bonds during their initial public offering (IPO) when they are issued by eligible government-backed organisations. Applications can be submitted through banks, brokers, or online investment platforms.

Since fresh issuances are currently limited, investors can also buy existing tax-free bonds from the secondary market through a demat account and a trading account.

Before investing, it is important to evaluate factors such as the bond’s interest rate, maturity period, issuer credibility, and market liquidity.

How to redeem Tax-Free Bonds?

Tax-free bonds are automatically redeemed upon maturity by the issuing organisation. The principal amount is credited to the investor’s registered bank account after the maturity date.

Investors who do not wish to hold the bonds until maturity can sell them on stock exchanges through their trading account, subject to prevailing market prices and liquidity conditions.

Selling bonds before maturity through the stock exchange sale may result in capital gains or capital losses, depending on market conditions and the selling price.
