Complete Guide to Bond Taxation in India: Interest, Capital Gains & Tax Strategies

One of the biggest mistakes bond investors make is focusing only on the headline yield and ignoring taxes. A 9% corporate bond might actually give you less post-tax return than a 7% government bond, depending on your tax bracket.

Understanding bond taxation is crucial for:

• Calculating actual returns
• Choosing between different bond types
• Planning tax-efficient investments
• Maximizing your wealth creation

This comprehensive guide breaks down everything about bond taxation in India - from interest income to capital gains, with real examples and tax-saving strategies.

The Two Types of Bond Income (And How Each is Taxed)

When you invest in bonds, you can earn income in two ways:

1. Interest Income (Coupon Payments)

This is the regular interest you receive from bonds - usually paid semi-annually.

How it's taxed: Added to your total income and taxed at your income tax slab rate.

Example:

• You hold a ₹10,00,000 bond paying 8% annual interest
• You receive ₹80,000 per year as interest
• If you're in the 30% tax bracket: Tax = ₹24,000
• Post-tax interest: ₹56,000 (effective yield: 5.6%)

2. Capital Gains (Price Appreciation)

This is the profit you make when you sell a bond for more than your purchase price.

How it's taxed: Depends on how long you held the bond (holding period)

Example:

• You bought a bond for ₹95,000
• You sold it for ₹1,02,000
• Capital gain: ₹7,000
• Tax depends on whether it's short-term or long-term gain

Let's dive deeper into each type.

Interest Income Taxation: The Complete Picture

General Rule: Fully Taxable at Slab Rate

Interest income from bonds is classified as "Income from Other Sources" and is:

• Added to your total taxable income
• Taxed according to your income tax slab
• No TDS is deducted on most bonds (with some exceptions)

Current Income Tax Slabs (FY 2024-25)

Old Tax Regime:

• Up to ₹2.5 lakh: Nil
• ₹2.5-5 lakh: 5%
• ₹5-10 lakh: 20%
• Above ₹10 lakh: 30%
• Plus cess: 4% on tax amount

New Tax Regime (without deductions):

• Up to ₹3 lakh: Nil
• ₹3-7 lakh: 5%
• ₹7-10 lakh: 10%
• ₹10-12 lakh: 15%
• ₹12-15 lakh: 20%
• Above ₹15 lakh: 30%
• Plus cess: 4% on tax amount

Real Example: Interest Income Taxation

Scenario: You invest ₹10,00,000 across different bonds

Portfolio:

• ₹5,00,000 in G-Sec at 7.2% → Interest: ₹36,000/year
• ₹3,00,000 in AAA corporate bond at 8.5% → Interest: ₹25,500/year
• ₹2,00,000 in SDL at 7.5% → Interest: ₹15,000/year
• Total interest income: ₹76,500/year

If you're in 30% tax bracket (Old Regime):

• Tax on interest: ₹76,500 × 30% = ₹22,950
• Cess (4%): ₹918
• Total tax: ₹23,868
• Post-tax income: ₹52,632 (effective yield: 5.26%)

If you're in 20% tax bracket:

• Tax: ₹15,300 + cess ₹612 = ₹15,912
• Post-tax income: ₹60,588 (effective yield: 6.06%)

If you're in 5% tax bracket:

• Tax: ₹3,825 + cess ₹153 = ₹3,978
• Post-tax income: ₹72,522 (effective yield: 7.25%)

Key Insight: Your effective bond yield reduces significantly based on your tax bracket. Always calculate post-tax returns when comparing investments.

TDS on Bond Interest: What You Need to Know

Government Bonds (G-Secs, T-Bills, SDLs):

• No TDS is deducted
• You must declare interest in your ITR and pay tax

Corporate Bonds:

• TDS rate: 10% if interest exceeds ₹5,000 per year (from one issuer)
• Deducted before crediting interest to you
• Can claim refund if tax liability is lower than TDS

Tax-Free Bonds:

• No TDS (since interest is tax-exempt)
• No need to declare in ITR (though advisable for record-keeping)

How to Report Bond Interest in Your ITR

Step 1: Gather interest certificates

• Check your email/portal for Form 16A (if TDS was deducted)
• Download statements from RBI Retail Direct or your Demat account

Step 2: Report under "Income from Other Sources"

• Enter total interest received during the financial year
• Enter TDS deducted (if any) under "TDS on Other than Salary"

Step 3: Pay balance tax

• If TDS < actual tax liability, pay the difference
• If TDS > actual tax liability, claim refund

Capital Gains Taxation: Listed vs Unlisted Bonds

This is where bond taxation gets interesting. The tax treatment differs based on:

1. Type of bond (listed or unlisted)
2. Holding period (short-term or long-term)

What Are Listed vs Unlisted Bonds?

Listed Bonds:

• Traded on stock exchanges (NSE/BSE)
• Most government bonds and many corporate bonds
• Can be bought/sold in secondary market

Unlisted Bonds:

• Not traded on exchanges
• Bought directly from issuer or through private placement
• Limited liquidity

How to check: If you bought it on an exchange or via RBI Retail Direct secondary market, it's likely listed.

Listed Bonds: Capital Gains Taxation

Holding Period Definition

• Short-term: Held for 12 months or less
• Long-term: Held for more than 12 months

Tax Rates (As per Budget 2024)

Short-Term Capital Gains (STCG):

• Taxed at your income tax slab rate
• Added to your total income

Long-Term Capital Gains (LTCG):

• Taxed at 12.5% (without indexation)
• No indexation benefit from FY 2024-25 onwards

Example: Listed Bond Capital Gains

Scenario 1: Short-term (held 10 months)

• Purchase price: ₹9,50,000
• Sale price: ₹10,20,000
• Capital gain: ₹70,000
• Tax: ₹70,000 × 30% (your slab rate) = ₹21,000

Scenario 2: Long-term (held 3 years)

• Purchase price: ₹9,50,000
• Sale price: ₹10,50,000
• Capital gain: ₹1,00,000
• Tax: ₹1,00,000 × 12.5% = ₹12,500

Budget 2024 Change: Previously, LTCG was taxed at 10% (above ₹1 lakh) with indexation benefit. New rate is 12.5% without indexation.

Unlisted Bonds: Capital Gains Taxation

Holding Period Definition

• Short-term: Held for 36 months or less
• Long-term: Held for more than 36 months

Notice: Longer holding period requirement compared to listed bonds (36 months vs 12 months)

Tax Rates

Short-Term Capital Gains (STCG):

• Taxed at your income tax slab rate

Long-Term Capital Gains (LTCG):

• Taxed at 12.5% (without indexation from FY 2024-25)

Example: Unlisted Bond Capital Gains

Scenario: Held for 40 months (long-term)

• Purchase price: ₹10,00,000
• Sale price: ₹11,50,000
• Capital gain: ₹1,50,000
• Tax: ₹1,50,000 × 12.5% = ₹18,750

The Impact of Removing Indexation (Budget 2024)

Prior to FY 2024-25, long-term capital gains allowed indexation - adjusting purchase price for inflation.

Old vs New: Real Example

Bond purchased in 2020 for ₹10,00,000, sold in 2024 for ₹12,00,000

Old Method (with indexation):

• Indexed purchase price: ₹10,00,000 × (348/301)* = ₹11,56,146
• Capital gain: ₹12,00,000 - ₹11,56,146 = ₹43,854
• Tax at 10%: ₹4,385

New Method (without indexation):

• Capital gain: ₹12,00,000 - ₹10,00,000 = ₹2,00,000
• Tax at 12.5%: ₹25,000

*Cost Inflation Index values

Impact: Higher effective tax for many long-term investors, especially during high inflation periods.

However: For shorter holding periods or lower inflation scenarios, 12.5% without indexation might be better than 10% with indexation.

Tax-Free Bonds: The Holy Grail for High-Income Investors

Tax-free bonds are a special category where interest income is completely exempt from tax.

What Are Tax-Free Bonds?

Issued by government-backed entities like:

• National Highways Authority of India (NHAI)
• Indian Railway Finance Corporation (IRFC)
• Power Finance Corporation (PFC)
• Housing and Urban Development Corporation (HUDCO)

Key Features:

• Interest is 100% tax-free under Section 10(15)(iv)(h)
• Long tenure (10-20 years typically)
• AAA-rated (very safe)
• Limited issuance (sold out quickly)

When Do Tax-Free Bonds Make Sense?

If you're in 30% tax bracket:

Wait, how is 5.5% better than 9%?

Calculation:

• 9% corporate bond after 30% tax = 9% × 0.7 = 6.3%
• 5.5% tax-free bond after 0% tax = 5.5%

Tax-equivalent yield formula:

Tax-Free Yield ÷ (1 - Your Tax Rate) = Equivalent Taxable Yield
5.5% ÷ (1 - 0.30) = 7.86%

So a 5.5% tax-free bond is equivalent to a 7.86% taxable bond for someone in the 30% bracket!

Real Example: Tax-Free vs Taxable Bonds

Investment: ₹20,00,000 for 10 years

Option 1: Taxable Corporate Bond at 8.5%

• Annual interest: ₹1,70,000
• Tax (30% bracket): ₹51,000
• Post-tax interest: ₹1,19,000/year
• 10-year post-tax earnings: ₹11,90,000

Option 2: Tax-Free Bond at 5.5%

• Annual interest: ₹1,10,000
• Tax: ₹0
• Post-tax interest: ₹1,10,000/year
• 10-year earnings: ₹11,00,000

While Option 1 earns slightly more, Option 2 offers:

• Complete tax certainty (no future tax rate risk)
• Simpler tax filing
• Peace of mind

Verdict: Tax-free bonds are excellent for investors in 30% tax bracket, especially for long-term goals.

Are Tax-Free Bonds Really "Tax-Free"?

Interest income: Yes, 100% tax-free

Capital gains: NOT tax-free

If you sell tax-free bonds before maturity in the secondary market:

• Any capital gains are taxed normally (LTCG at 12.5% if held >12 months)

Example:

• Bought tax-free bond for ₹10,00,000
• Sold for ₹11,00,000 after 2 years
• Capital gain: ₹1,00,000
• Tax: ₹12,500 (LTCG at 12.5%)

Tip: Buy tax-free bonds with the intention to hold till maturity for maximum benefit.

Old Tax Regime vs New Tax Regime: Which is Better for Bond Investors?

This depends on your total income and deductions.

Old Tax Regime Advantages

• Lower tax rates at higher slabs (if you claim deductions)
• Deductions under 80C, 80D, 80G, HRA, etc.
• Better for high-income individuals with significant deductible investments

New Tax Regime Advantages

• Lower tax rates without claiming deductions
• Simpler tax filing
• Better for those without many deductions

Bond Income Impact: Example

Scenario: Annual income ₹15,00,000 + Bond interest ₹1,00,000

Old Regime (with ₹2,00,000 deductions):

• Taxable income: ₹14,00,000
• Tax: ~₹2,62,500
• Average tax rate: ~17.5%
• Bond interest post-tax: ₹1,00,000 - ₹30,000 = ₹70,000

New Regime (no deductions):

• Taxable income: ₹16,00,000
• Tax: ~₹2,60,000
• Average tax rate: ~16.25%
• Bond interest post-tax: Higher effective tax on bond interest

Verdict: For most bond investors with deductions, the old regime remains beneficial.

Tax-Saving Strategies for Bond Investors

1. Choose the Right Bond Type Based on Tax Bracket

If in 30% bracket:

• Prioritize tax-free bonds when available
• G-Secs for safety (post-tax ~5%)
• High-rated corporate bonds only if yield > 10%

If in 20% bracket:

• Mix of G-Secs and corporate bonds
• Tax-free bonds still beneficial but less critical

If in 5% or nil bracket:

• Focus on highest yield taxable bonds
• Tax-free bonds offer no advantage

2. Hold Bonds Long-Term

Benefit: LTCG taxed at 12.5% vs your slab rate for STCG

Example:

• ₹1,00,000 capital gain
• If short-term (30% bracket): Tax = ₹30,000
• If long-term: Tax = ₹12,500
• Savings: ₹17,500

Strategy: Plan to hold bonds for at least 12 months before selling.

3. Time Your Bond Sales

Harvest losses: If you have capital gains from other sources, sell loss-making bonds to offset.

Example:

• Stock sale gain: ₹2,00,000
• Bond sold at loss: ₹50,000
• Net taxable gain: ₹1,50,000 (saves tax on ₹50,000)

4. Distribute Bonds Across Family Members

If you're in a high tax bracket, consider gifting bonds to:

• Spouse (if in lower bracket)
• Adult children (if in lower bracket)
• Parents (if income is low)

Clubbing rules: Income from assets gifted to spouse is clubbed back to your income. But gifts to adult children or parents are not clubbed.

Example:

• You (30% bracket) have ₹20,00,000 to invest
• Gift ₹10,00,000 to adult child (nil bracket)
• Child earns ₹80,000 interest tax-free
• You earn ₹80,000 interest, pay ₹24,000 tax
• Family tax savings: ₹24,000 vs ₹48,000 if you held all

5. Use Tax-Free Bonds for Retirement Corpus

Keep tax-free bonds in your retirement portfolio:

• Tax-free income during retirement (when income is lower)
• No TDS hassles
• Predictable cash flows

6. Prefer Listed Bonds for Flexibility

Why: 12-month holding period vs 36 months for unlisted bonds

If you might need to sell, buy listed bonds for:

• Quicker LTCG qualification
• Better tax efficiency
• More liquidity

7. Avoid Frequent Trading

Every sale triggers capital gains tax. Buy-and-hold strategy minimizes:

• Tax events
• Transaction costs
• Complexity in tax filing

Special Cases and Scenarios

NRI Bond Taxation

Interest Income:

• TDS: 20% (or treaty rate, whichever is lower)
• Must file ITR to claim refund if applicable

Capital Gains:

• Same as residents (STCG/LTCG rules apply)
• TDS on sale: 20% on LTCG, slab rate on STCG

Sovereign Gold Bonds (SGBs)

Interest: 2.5% per annum, taxable at slab rate

Capital Gains:

• On secondary market sale: LTCG at 12.5% (if held >12 months)
• On redemption at maturity: Completely tax-free

Tax Tip: SGBs offer the best of both worlds - regular interest + tax-free capital appreciation if held till maturity.

Zero-Coupon Bonds (Like T-Bills)

Taxation: The discount (difference between purchase and face value) is treated as interest income

Example:

• 91-day T-Bill face value: ₹10,00,000
• Purchase price: ₹9,82,500
• Discount (interest): ₹17,500
• Taxed as: Interest income at your slab rate

Not capital gains: Even though you "buy low, sell high", it's interest income for tax purposes.

Perpetual Bonds

Some bonds have no maturity (perpetual). For tax:

• Interest income taxed normally
• If sold, capital gains rules apply based on holding period

How to File Bond Income in Your ITR

Step-by-Step Filing Guide

Step 1: Collect Documents

• Interest certificates (from RBI Retail Direct/broker)
• Form 16A (if TDS was deducted)
• Sale statements (for capital gains)

Step 2: Choose Right ITR Form

• ITR-2: If you have capital gains from bonds
• ITR-1 (Sahaj): If only interest income and simple finances

Step 3: Report Interest Income

• Go to "Income from Other Sources"
• Enter total interest under "Income from Savings Account/Deposits"
• Include government and corporate bond interest

Step 4: Report Capital Gains

• Go to "Capital Gains" section
• For listed bonds: Use "Short-term 15%" or "Long-term" section
• Enter purchase price, sale price, expenses
• System calculates tax automatically

Step 5: Claim TDS Credit

• Under "TDS on Other than Salary"
• Enter TDS details from Form 16A
• Claimed against total tax liability

Step 6: Pay Balance Tax/Claim Refund

• If total tax > TDS, pay via challans
• If TDS > total tax, refund will be processed

Common Tax Mistakes to Avoid

1. Not Reporting Interest Income

Mistake: Thinking "no TDS means no tax"

Reality: All bond interest is taxable (except tax-free bonds). Not reporting can lead to notices and penalties.

2. Confusing Holding Period

Mistake: Assuming all bonds have 12-month LTCG period

Reality: Unlisted bonds need 36 months. Check before selling.

3. Ignoring Accrued Interest

When buying bonds in secondary market, you pay accrued interest (interest accumulated since last payment).

Tax treatment: You can claim this as expense when calculating capital gains.

4. Not Maintaining Records

Keep records of:

• Purchase confirmations
• Sale confirmations
• Interest certificates
• Holding statements

Why: Needed for accurate tax filing and in case of scrutiny.

5. Forgetting About Clubbing Rules

Gifting bonds to minor children or spouse without understanding clubbing can backfire - income gets clubbed back to you.
