Tax-Free Bonds in India: Your Complete Investment Guide for 2025
What Are Tax-Free Bonds? The Smart Investor’s Secret Weapon
Tax-free bonds are government-backed debt instruments that offer completely tax-exempt interest income – making them the holy grail for high-income investors seeking predictable, risk-free returns. Unlike regular bonds where you lose 30% of interest to taxes, these gems let you keep every rupee you earn.
Think of it this way: If you’re in the 30% tax bracket and earn ₹60,000 annually from a regular bond, you keep only ₹42,000. With tax-free bonds earning the same amount, you pocket the full ₹60,000. That’s an instant 43% boost to your actual returns!
Who Issues These Golden Tickets?
India’s most trusted infrastructure giants issue tax-free bonds:
- NHAI (National Highways Authority of India)
- IRFC (Indian Railway Finance Corporation)
- PFC (Power Finance Corporation)
- REC (Rural Electrification Corporation)
- HUDCO (Housing and Urban Development Corporation)
- NABARD (National Bank for Agriculture and Rural Development)
- IREDA (Indian Renewable Energy Development Agency)
- NTPC Limited
The Tax-Free Bonds Advantage: Why Smart Money Chooses Them
1. Complete Tax Immunity
Your interest income enjoys 100% exemption under Section 10(15) of the Income Tax Act. No TDS, no tax liability, no headaches during filing season.
2. Rock-Solid Security
These bonds carry AAA credit ratings because they’re backed by the Government of India. Your principal is as safe as money in a government vault.
3. Predictable Income Stream
Fixed coupon rates (typically 5.5% to 8.5%) mean you know exactly how much you’ll earn each year for the next 10-20 years.
4. No Investment Ceiling
Unlike Section 80C investments capped at ₹1.5 lakh, you can invest unlimited amounts in tax-free bonds.
Types of Tax-Free Bonds: Choose Your Infrastructure Hero
| Bond Type | Issuer | Sector Focus | Typical Tenure |
|---|---|---|---|
| Infrastructure Bonds | NHAI | Roads & Highways | 10-20 years |
| Power Bonds | PFC, REC | Electricity Generation | 15-20 years |

| Housing Bonds | HUDCO, NHB | Affordable Housing | 10-20 years |
| Renewable Energy Bonds | IREDA | Green Energy Projects | 15-20 years |
How to Calculate Your Tax-Free Bond Returns
Understanding Yield to Maturity (YTM) is crucial since most bonds now trade at a premium in the secondary market.
YTM Formula:
YTM = (Annual Interest + (Face Value – Purchase Price) / Years to Maturity) / ((Face Value + Purchase Price) / 2)
Real Example:
NHAI Bond Details:
- Face Value: ₹1,000
- Coupon Rate: 6%
- Current Market Price: ₹1,200
- Years to Maturity: 10
Calculation:
- Annual Interest = ₹1,000 × 6% = ₹60
- YTM = (₹60 + (₹1,000 – ₹1,200) / 10) / ((₹1,000 + ₹1,200) / 2)
- YTM = (₹60 – ₹20) / ₹1,100 = 3.64%
Current Yield = ₹60 / ₹1,200 × 100 = 5%
The Reality Check: Tax-Free Bonds Aren’t Perfect
Major Limitations You Must Know
- No New Issues Since 2016 The government stopped issuing fresh tax-free bonds in 2016. You can only buy existing bonds in the secondary market, often at 15-20% premium.
- Capital Gains Are Taxable While interest is tax-free, selling bonds before maturity triggers capital gains tax:
- Short-term (< 1 year): Taxed as per your income slab
- Long-term (> 1 year): 10% without indexation or 20% with indexation
- Inflation Risk Fixed returns may lose purchasing power. A 6% bond might look attractive today, but what about inflation 15 years later?
- Liquidity Constraints Secondary market trading can be thin, making it harder to exit quickly at fair prices.
Who Should Invest in Tax-Free Bonds?
Perfect For:
- High-income earners in 30% tax bracket
- Risk-averse investors prioritizing capital safety
- Retirees seeking steady income streams
- Long-term planners comfortable with 10-20 year commitments
Not Ideal For:
- Young investors who need liquidity
- Growth seekers wanting inflation-beating returns
- Short-term investors needing money within 5 years

Smart Investment Strategies for Tax-Free Bonds
The Laddering Approach
Instead of buying all bonds with the same maturity, create a ladder:
- 25% in 10-year bonds
- 25% in 15-year bonds
- 25% in 20-year bonds
- 25% keep liquid for opportunities
This strategy provides regular maturity proceeds for reinvestment.
The Premium-Discount Play
Look for bonds trading near face value or at slight discounts. Avoid bonds at heavy premiums (>20%) as they severely impact your YTM.
Tax-Free Bonds for NRIs: Special Considerations
Good News: NRIs can invest in tax-free bonds on both repatriable and non-repatriable basis.
Key Points:
