What Are Taxable Bonds?

If you are in the 30% tax bracket, your bond interest is taxed at 30%. If you are in the 20% bracket, it is taxed at 20%. The higher your income, the more tax you pay on the same interest. Examples of taxable bonds include government bonds, corporate bonds, and most fixed deposits.

These bonds are issued by government-backed companies. Companies like National Housing Bank, Power Finance Corporation, NTPC, and National Highways Authority of India issue them. They raise money for infrastructure projects . The interest is exempt under Section 10(15) of the Income Tax Act .
Taxable vs Tax-Free: The Real Difference
- The coupon rate on tax-free bonds is usually lower. But because you pay no tax, your after-tax return is higher. This is the key point.
- Let me give you an example from real data. Tax-free bonds currently yield around 4.4% to 4.7% . If you are in the 30% tax bracket, this is equal to a taxable yield of about 7.8% to 8.2%. Bank fixed deposits give 6.2% to 7% before tax. After tax, they give you much less .
So even though the tax-free bond coupon looks smaller, you keep all of it.
Tax-Free vs Taxable Bonds Calculator
You can use a simple formula to compare. It is called the tax-equivalent yield .
Tax-Equivalent Yield = Tax-Free Bond Yield ÷ (1 – Your Tax Rate)
- Example: A tax-free bond gives 4.5%. You are in the 30% tax bracket.
- Tax-equivalent yield = 4.5 ÷ (1 – 0.30) = 6.43%.
This means a taxable bond must give you 6.43% to match the tax-free bond's return. If the taxable bond gives less, the tax-free bond is better for you.
You can find free calculators online. Broadridge offers a taxable vs tax-free bonds calculator . Some apps also do this calculation .
How Do Tax-Free Bonds Work?
- Tax-free bonds work like regular bonds. You invest a lump sum. You get interest every year. The interest is paid directly to your bank account. At maturity, you get your principal back.
- The tenure is usually 10, 15, or 20 years . There is no lock-in period for listed bonds. You can sell them on the stock exchange if you need money. But finding a buyer can be a challenge for less popular bonds .
You can hold them in Demat or physical form. PAN is mandatory .
