Real returns depend on what survives after tax, not the headline yield.
Bond taxation in India runs on two separate tracks: interest income and capital gains, each governed by its own rules and holding-period thresholds. Interest is taxed at your slab rate, full stop. Capital gains treatment, however, changes dramatically based on whether the bond is listed or unlisted, and how long you've held it.
This guide covers interest taxation, capital gains rules for listed versus unlisted bonds, TDS provisions, and tax-efficient strategies worth considering. Tax law here shifts often, so verify current rates against the latest Finance Act before you file.
Key Takeaways
- Bond interest is taxed at your slab rate, with only select PSU bonds tax-free
- Listed bonds earn LTCG after 12 months; unlisted bonds sold after July 23, 2024 are always STCG
- TDS under Section 193 kicks in above a threshold, but Form 15G/15H can help avoid it
- Section 54EC bonds still let you shield long-term capital gains from property sales
How Interest Income from Corporate Bonds Is Taxed
Coupon interest from a corporate bond is classified as "Income from Other Sources" under Section 56 and gets added straight to your Gross Total Income. There's no special rate, no separate slab. It simply joins your salary, rental income, or business profits and gets taxed as per your applicable bracket.
Say an investor holds a bond paying ₹80,000 in annual interest, and their total income (including salary) places them in the 20% slab. That ₹80,000 doesn't get taxed at some preferential bond rate. It's taxed at 20%, just like any other rupee of income in that bracket.
Cumulative vs Payout Bonds
Not all bonds pay interest annually, and the tax timing differs:
- Regular payout bonds pay interest each year, which becomes taxable in the year it's received or accrued (depending on whether you follow the cash or mercantile method)
- Cumulative bonds don't pay interest until maturity, but the interest still accrues each year and becomes taxable annually based on accrual, not just in the redemption year
- Deep-discount or cumulative instruments often use a market-linked valuation method for determining annual accretion, per CBDT guidance
Missing this distinction is a common filing error. Investors assume cumulative bonds are tax-free until maturity; they're not.
Rebate and Exemption Limits
Under the new tax regime for FY2024-25, resident individuals get a Section 87A rebate of up to ₹25,000 if total income doesn't exceed ₹7,00,000. This can effectively wipe out tax on modest bond interest for lower-income investors. Always confirm the current year's slab structure and rebate ceiling, since these get revised in nearly every Budget.
NRI-Specific Considerations
NRIs face a materially different withholding regime. Interest income typically attracts a higher TDS rate under Section 195, plus applicable surcharge and cess, compared to the resident rate under Section 193. Two things can reduce this burden:
- DTAA benefits: If India has a tax treaty with the investor's country of residence, a lower rate may apply
- Form 10F and Tax Residency Certificate (TRC): Both are mandatory to claim treaty relief, and Form 10F must now be filed electronically
Capital Gains Tax on Corporate Bonds: Listed vs Unlisted
This is where things get genuinely complicated, and where most retail investors trip up. Capital gains fall into two buckets: Short-Term (STCG) and Long-Term (LTCG). Which one applies depends entirely on the holding period and the listing status of the bond.
Listed Corporate Bonds
Listed bonds become long-term after 12 months of holding. For transfers on or after July 23, 2024, gains beyond that threshold attract LTCG tax at 12.5% without indexation. Hold for 12 months or less, and the gain is taxed as STCG at your regular slab rate.
Unlisted Corporate Bonds
Unlisted bonds used to get a longer rope: a 36-month holding period for LTCG eligibility, with indexation benefits. That changed with the Finance (No. 2) Act, 2024.
For any unlisted bond transferred, redeemed, or matured on or after July 23, 2024, gains are deemed STCG under Section 50AA, irrespective of how long you held it. No indexation, no long-term concession, taxed at your slab rate regardless.
A Quick Calculation
Suppose you bought a listed NCD for ₹1,00,000 and sold it 18 months later for ₹1,15,000.
- Holding period exceeds 12 months → LTCG applies
- Gain: ₹15,000
- Tax at 12.5% (no indexation): ₹1,875
Now compare that to an unlisted bond bought at the same price, sold after 18 months for the same ₹1,15,000, on or after July 23, 2024:
- Deemed STCG under Section 50AA regardless of the 18-month hold
- ₹15,000 gain taxed at your full slab rate, potentially 30% instead of 12.5%
That's a meaningful difference for anyone holding unlisted NCDs assuming they'd get long-term treatment.
Bonds vs Debt Mutual Funds: Don't Confuse the Two
Post-2023 headlines about "indexation removal" mostly referred to debt mutual fund units, not direct bonds. Section 50AA originally targeted specified debt-fund units and Market-Linked Debentures from April 2023; unlisted direct bonds were folded in only via the 2024 amendment.
Direct listed bonds continue to sit under Sections 2(42A) and 112. Don't apply debt-fund logic to your NCD portfolio by mistake.
The MLD Trap
Here's a nuance retail investors often miss entirely: Market-Linked Debentures (MLDs) are taxed as STCG regardless of how long you hold them, a rule in force since April 2024.
If your bond's return is linked to an index or another security rather than a fixed coupon, check whether it qualifies as an MLD before assuming standard bond tax rules apply.
TDS on Corporate Bond Interest
Under Section 193, the company issuing your bond deducts tax at source before crediting interest to your account. The standard resident rate is 10%.
A narrow exemption applies to interest on debentures of a widely-held public company, paid by account-payee cheque to a resident individual or HUF. This threshold has moved from ₹5,000 to ₹10,000 in recent Finance Acts, so confirm the figure applicable to your assessment year.
Two forms help you avoid unnecessary deduction:
- Form 15G – for individuals (below 60) whose estimated tax liability for the year is nil
- Form 15H – for senior citizens, with a similar nil-tax declaration requirement
Submitting these at the start of the financial year prevents the issuer from deducting TDS in the first place, rather than making you claim a refund later.
A practical habit worth building: reconcile TDS shown against your bond interest with Form 26AS and the Annual Information Statement (AIS) before filing your return. Mismatches are one of the most common reasons for delayed refunds or notices.
The TDS picture changes substantially for NRI investors. Under Section 195, rates run steeper than the resident 10%, and can climb to 20% or more under Section 206AA if PAN or valid DTAA documentation is missing. Getting this paperwork right upfront avoids costly back-and-forth with the tax department later.
Corporate Bonds vs Fixed Deposits & Tax-Free Bonds: Which Is More Tax-Efficient?
FD interest is always taxed at your slab rate, with TDS kicking in above a threshold. No capital gains angle exists because FDs aren't transferable securities. Corporate bonds, by contrast, can offer a real edge if listed and held beyond the 12-month LTCG threshold.
| Feature | Fixed Deposit | Listed Corporate Bond (held >12 months) |
|---|---|---|
| Interest tax | Slab rate | Slab rate |
| Gain on sale | Not applicable | 12.5% LTCG, no indexation |
| Liquidity | Premature withdrawal penalty | Tradable on exchange |
| TDS | Section 194A | Section 193 |
The Tax-Free Bond Advantage
Beyond the general FD-versus-bond comparison, one bond category deserves closer attention: tax-free PSU bonds, which carry interest exempt under Section 10(15), including older NHAI or REC bonds still trading on NSE.
For someone in the 30% bracket, a tax-free bond yielding 6% has the same after-tax impact as a taxable instrument yielding roughly 8.6%, calculated as 6% ÷ (1 − 0.30). That's the "tax-equivalent yield" concept, and it explains why these bonds appeal disproportionately to higher-bracket investors. Just remember: the exemption covers interest only, not any capital gain on resale.
Beyond the tax treatment, listed bonds also win on flexibility: you can exit on the exchange whenever you need liquidity, without the exit-load-style penalty an FD imposes on premature withdrawal.
Smart Tax-Efficient Strategies for Corporate Bond Investors
A few structural choices can meaningfully change your post-tax outcome:
Favour listed bonds and hold beyond 12 months. This shifts taxation from slab rate to the flat LTCG rate, often a significant saving for anyone above the 20% bracket.
Use Section 54EC bonds for property gains. Sold land or a building and booked long-term capital gains? Investing the proceeds in specified bonds (REC, PFC, IRFC, NHAI) within 6 months exempts that gain from tax. The cap is ₹50 lakh across the transfer year and the next, with a 5-year lock-in, applying only to property gains, not bond sales.
Consider tax-loss harvesting. If you're sitting on capital losses from equities or other bond sales, offsetting them against gains realised elsewhere in your fixed-income book can reduce your overall tax bill for the year.
Be cautious with income-splitting. Investing through a spouse or parent in a lower bracket sounds appealing, but clubbing provisions under Sections 60–64 often attribute that income back to the original transferor anyway. This needs careful structuring, not a casual workaround.
Getting these calls right (listed versus unlisted, timing a sale around the 12-month mark, deciding whether 54EC fits your specific gain) usually benefits from a second pair of eyes.

Frequently Asked Questions
What taxes do you pay on corporate bonds?
You pay tax on two fronts: interest income at your slab rate, and capital gains (STCG or LTCG) depending on listing status and holding period. TDS is also deducted at source on interest under Section 193.
Is a corporate bond better than an FD?
Corporate bonds can deliver better post-tax returns if listed and held beyond 12 months, since LTCG rates beat slab-rate FD taxation. They also offer exchange liquidity, but carry higher credit risk than bank FDs.
What is the TDS rate on corporate bond interest?
Section 193 sets the resident TDS rate at 10%, above a specified annual threshold. Confirm the current threshold for your assessment year, and use Form 15G/15H to avoid deduction if your tax liability is nil.
Are unlisted corporate bonds taxed differently from listed ones?
Yes. Listed bonds get LTCG treatment after 12 months at 12.5%. Unlisted bonds transferred on or after July 23, 2024 are always treated as STCG under Section 50AA, regardless of how long you held them.
Can NRIs invest in corporate bonds in India and how are they taxed?
NRIs can invest, mainly in listed corporate and PSU bonds, though eligibility varies by issuer. Interest attracts higher TDS under Section 195 unless reduced via DTAA benefits, supported by Form 10F and a Tax Residency Certificate.
How can I save tax on capital gains using corporate bonds?
Section 54EC lets you reinvest long-term capital gains from property sales into specified bonds (REC, PFC, IRFC, NHAI) within 6 months, up to the applicable investment cap, exempting that gain from tax.
