Complete List of Government-Backed Tax-Free Bonds

When investors say “tax-free bonds,” they’re usually referring to government-backed public sector issuers that raised long-term money through bonds where the interest income is exempt from tax (commonly under Section 10(15) of the Income-tax Act, subject to the specific bond terms). I prefer calling them tax-beneficial bonds because it keeps the focus on what matters: the post-tax outcome.

A key point upfront: fresh tax-free bond issuances have been rare in recent years. What most investors access today is the secondary market, where these bonds trade on exchanges and prices move up or down like any other listed security.

The core “tax free bonds list” investors track

Below is the practical list I keep in mind—these issuers are widely recognised for having issued tax-free bonds in past programs and are often seen in secondary trading (availability varies by series and maturity):

• NHAI (National Highways Authority of India) – long-tenor tax-free bonds issued in earlier windows
  
   
• REC (Rural Electrification Corporation) – multiple series across tenors
  
   
• PFC (Power Finance Corporation) – known for power-sector financing and tax-free bond programs
  
   
• IRFC (Indian Railway Finance Corporation) – railway financing tax-free bond series
  
   
• HUDCO (Housing and Urban Development Corporation) – housing/urban infra focused series
  
   
• NTPC – select tax-free bond issuances from earlier programs
  
   
• NHPC – hydro power focused tax-free bond series
  
   
• IIFCL (India Infrastructure Finance Company) – infrastructure finance issuances in earlier years
  
   
• AAI (Airports Authority of India) – issuances seen in older tax-free bond programs (series-specific)
  
   

Common maturities: 10, 15, and 20 years (varies by issuer and series).
 What changes in the secondary market: your effective return depends on the price you pay, not just the original coupon.

How I verify a bond before considering it

A “list” is only useful if it helps you confirm what you’re actually buying. I typically check:

1. Issuer + Series/Tranche (the same issuer can have multiple tax-free bond series)
   
    
2. ISIN (unique identifier—this prevents mix-ups)
   
    
3. Coupon rate and interest payment schedule
   
    
4. Maturity date and remaining tenor
   
    
5. Credit rating (historically high for these issuers, but always verify the current rating)
   
    
6. Exchange listing and recent traded volumes (liquidity matters more than people admit)
   
    

How people buy them today

Since these instruments are usually accessed via the market, the process is similar to any listed bond purchase. In simple terms, you need a demat account, and you can place orders through a broker or a regulated online platform. If your preference is convenience and transparency, you can also buy bonds online by comparing available series, yields, and maturities, and then completing the purchase digitally (subject to availability and suitability).

Risks I don’t ignore (even with government-backed issuers)

• Price risk: bond prices move with interest rates; selling before maturity can lead to gains or losses.
  
   
• Liquidity risk: some series trade thinly, so exit may not be instant at your preferred price.
  
   
• Tax reality: while interest on eligible tax-free bonds is exempt, capital gains from selling can be taxable depending on holding period and rules applicable to listed bonds.
  
   

Closing thought

A government-backed label can make these bonds feel straightforward, but the real discipline is in matching tenor, liquidity, and post-tax return to your needs. I treat this list as a starting point—then I verify the exact series details before taking any decision.
