Treating the three as one product has a cost, because they differ on the points that separate them. One pays interest that is exempt but is no longer issued, so it can only be bought from an existing holder on the secondary market; one is available at issue but locks capital up and exists to shelter a specific kind of gain; one is taxed like any other corporate bond. A yield quoted for any of them means something different in each case, and a coupon quoted without its tax treatment is not comparable across the three.
This article separates the three on tax treatment, tenure, and what each one is actually for.
Key Takeaways
Legacy tax-free bonds were issued in public offers around 2012 to 2014 and no fresh tranches have been issued since; they can only be bought in the secondary market, and their interest remains exempt
Capital gain bonds are an on-tap issue for sheltering a long-term gain from the sale of land or a building, with a ₹50 lakh cap per financial year, a five-year lock-in and a taxable coupon
The ₹50 lakh cap applies across all capital gain bond issuers combined, not per issuer — a point that catches investors who split an investment between two of them
Taxable NCDs are ordinary corporate bonds with market-linked coupons, and tax is deducted at source on interest above the prescribed threshold
From April 2026 the capital gain bond exemption sits under the Income-tax Act, 2025, with the terms otherwise unchanged
What Is HUDCO and Why Its Bonds Matter
HUDCO was established on 25 April 1970, wholly owned by the Government of India, with a mandate covering housing shortages and planned urban development. Historically a Mini Ratna, it received Navratna status on 18 April 2024.
As the technical arm of the Ministry of Housing and Urban Affairs, it participates in the delivery of major urban programmes, including:
PMAY (Housing for All)
AMRUT
Smart Cities Mission
For a bondholder the relevant feature is ownership and mandate: HUDCO is a government-owned entity lending into a policy programme, which is a different funding and governance position from a privately-owned non-banking financial company. That is a structural distinction, not a statement about credit outcomes.
To fund its lending it has issued bonds in three categories, each with its own tax treatment. Separating them is where most of the confusion resolves.
Types of HUDCO Bonds: Tax-Free, 54EC & Taxable NCDs
Legacy Tax-Free Bonds
These were issued in public offers around 2012 to 2014, under the exemption then available for interest on specified infrastructure bonds. No fresh tax-free tranches have been issued since; the route was closed for new issuance years ago.
The existing issues remain listed on the NSE and BSE and continue to pay exempt interest to whoever holds them. Because they are no longer issued, every purchase today is a secondary-market purchase at the price the market is quoting, which is the fact that governs everything else about them, and the subject of the section below.
54EC Capital Gain Bonds
These are an ongoing on-tap issue, available to an investor who has realised a long-term capital gain on a capital asset — in practice, most often land or a building — and wishes to claim the exemption available for reinvesting it.
The statutory terms are a ₹50 lakh cap per financial year, a five-year lock-in, and a fixed annual coupon that is taxable. From April 2026 the exemption is provided by the Income-tax Act, 2025, which succeeded the corresponding provision of the 1961 Act; the commercial terms of the bonds are unchanged by that transition, and the market continues to refer to them by the older section number.
Taxable NCDs
Ordinary corporate bonds, privately placed or listed, with market-linked coupons set at issuance. Interest is fully taxable and tax is deducted at source above the prescribed annual threshold. Coupons on individual series differ by issue date and tenure, and the terms of any specific series are in its own information memorandum.
| Bond Type | Coupon | Tenure | Tax on Interest | TDS |
|---|---|---|---|---|
| Legacy Tax-Free Bonds | Fixed at original issue; varies by series | Originally 10, 15 or 20 years | Exempt | No |
| 54EC Capital Gain Bonds | Fixed, set by the issuer for the series | 5 years | Taxable | Per the information memorandum |
| Taxable NCDs | Market-linked at issuance; varies by series | Up to 10 years | Fully taxable | Yes, above the threshold |
HUDCO Tax-Free Bonds: Interest Rates, Yields and Taxation
Because no new tax-free bonds are issued, the only route to one is the secondary market — bought through a demat account, at whatever price the market is quoting on the day.
That price is the whole of the analysis. These bonds were issued years ago with coupons fixed at the time, and market interest rates have moved since. Where market rates have fallen relative to the coupon, the bond trades above face value, and that premium compresses the yield to maturity an incoming buyer actually earns. The coupon is a fact about the security; the yield is a function of the price paid for it, and the two are frequently confused.
The practical consequence is that no yield figure quoted in an article is meaningful for a purchase made later. The live exchange quote, the accrued interest since the last coupon date and the resulting yield to maturity are what determine the return, and all three are visible at the point of purchase.
How the Tax Treatment Actually Works
Interest income: exempt from income tax, with no deduction at source
Capital gains on sale: fully taxable where the bond is sold in the secondary market above its purchase price
Holding period: the gain is long-term or short-term on the ordinary rules for a listed security
Tax-Equivalent Yield: A Working Example
The comparison between an exempt coupon and a taxable one cannot be made at face value, because one figure is pre-tax and the other is not.
Consider an exempt yield of 5.25% held by an investor in the 30% bracket, whose effective rate with cess is a little over 31%. A taxable instrument would have to yield materially more than 5.25% to leave the same amount after tax — in this case something above 7.5%. The gap between the two is the tax-equivalent yield, and it widens as the bracket rises: the same exempt coupon is worth more after tax to a higher-bracket investor than to a lower-bracket one.
The same logic applies to every exempt issuer in this category, not to HUDCO specifically, which is why a comparison across the exempt issues currently quoted is the relevant one rather than a comparison against a single name.
HUDCO 54EC Capital Gain Bonds: Saving Tax on Property Sales
Where land or a building has been sold at a long-term gain, these bonds are the statutory relief mechanism. Per the Income Tax Department's guidance on exemptions from capital gains, the exemption is the lower of three amounts: the capital gain, the amount actually invested, or ₹50 lakh.
The conditions that decide eligibility:
The investment must be made within six months of the date of transfer
The ₹50 lakh cap applies across all capital gain bond issuers combined in a financial year — not ₹50 lakh with each of them
The coupon is fixed for the series, and it is taxable
Five-year lock-in; the bonds are non-transferable and cannot be pledged as security for a loan
Eligible investors include individuals, HUFs, firms and companies, and NRIs investing through an NRO account on a non-repatriable basis
Where the bond is redeemed or converted to cash before five years, the exemption previously claimed is withdrawn and the gain becomes taxable. The lock-in is a condition of the exemption rather than a feature of the bond.
Across issuers: the statutory terms — the cap, the lock-in, the six-month window — are set by tax law and are therefore identical whichever issuer is used. What differs between them is ownership and sector mandate, and the mechanics of the application process. The terms of any specific series are in its current information memorandum.
Is It Safe and Worth Investing In HUDCO Bonds?
HUDCO's bond programmes carry credit ratings from ICRA, CARE and India Ratings. A rating is an agency's opinion on the issuer's ability to service the obligation, arrived at on that agency's methodology; it is reviewed periodically and can be revised in either direction, and the current rating on a given programme sits with the agency and in the issuer's own disclosures.
A rating also addresses credit risk alone. Three other exposures are unaffected by it:
Interest rate and duration risk. A long-tenure bond is highly sensitive to rate movements. Where yields rise after purchase, the market price falls, and that is realised by anyone who sells before maturity
Liquidity risk. Legacy tax-free bonds do not trade as actively as government securities. A large position sold quickly is sold at whatever price the book will absorb
Reinvestment risk during the capital gain bond lock-in. The coupon is fixed for five years and the bonds cannot be transferred, so a subsequent rise in market rates cannot be acted on
What each of the three bond types is for is therefore different, and none of them is identified here as suitable for any reader. A legacy tax-free bond addresses exempt income; a capital gain bond addresses a specific realised gain within a statutory deadline; a taxable NCD is ordinary corporate paper. Whether any of them fits depends on facts specific to you, including how long the capital can stay committed.
How Cambridge Wealth Can Help You Decide
Cambridge Wealth is an AMFI-registered Mutual Fund & SIF Distributor, ARN-172841. The tax computation on a capital gain is a chartered accountant's work.
What it can do on a question like this one is portfolio analysis and scheme information. A bond holding rarely sits alone: fixed-income exposure held through scheme categories often already carries similar duration and credit, and that overlap is not visible from statements read separately. Seeing the two together is what shows whether a fixed-income allocation is more concentrated in one kind of paper, or one part of the maturity curve, than was intended.
Every scheme considered for the research universe passes a documented 108-point research framework across 5,000+ Indian investment products, assessed on quantitative metrics and qualitative factors including structure, mandate, underlying holdings, liquidity and exit terms. If you are looking at the income side of a portfolio more broadly, the income-oriented approach is here.
Frequently Asked Questions
Is interest on HUDCO tax-free bonds taxable?
No, the interest is exempt and no tax is deducted at source on it. A gain on selling the bond in the secondary market is a separate event and is taxable in the ordinary way.
I want to buy a tax-free bond. What determines what I earn?
The price you pay, not the coupon printed on the bond. No fresh tranches are issued, so every purchase is in the secondary market, and where the bond trades above face value the premium compresses the yield to maturity below the coupon rate.
Are exempt yields comparable with FD rates?
Not directly. An exempt yield is already net of tax while a deposit rate is not, so the two have to be put on the same basis before they mean anything — and the gap between them widens with your tax bracket.
I sold a property last month. What is the deadline?
Six months from the date of transfer to make the investment, with the exemption capped at ₹50 lakh across all capital gain bond issuers combined in the financial year. The five-year lock-in then runs, and redeeming early withdraws the exemption.
Can an NRI use capital gain bonds?
Yes, through an NRO account on a non-repatriable basis, alongside individuals, HUFs, firms and companies. The statutory conditions — the window, the cap and the lock-in — apply identically.
What does the AAA rating on these programmes actually cover?
Credit risk only: it is an agency's opinion on the issuer's ability to service the obligation. It says nothing about the price falling if rates rise, about how easily a large position can be sold, or about being locked in at a fixed coupon for five years.

Bonds carry the credit risk of the issuer. A credit rating is an opinion of the rating agency, is subject to periodic review and revision, and does not address interest rate, liquidity or reinvestment risk. Bond prices move inversely to interest rates and a sale before maturity realises the market price on the day.
Capital gain bonds carry a statutory lock-in. Redemption or conversion to cash before the lock-in expires withdraws the exemption previously claimed and the gain becomes taxable.
