Corporate Bonds and NCDs India 2026: How to Invest via Online Bond Platforms, Yields, and Tax Rules

Corporate bonds and non-convertible debentures (NCDs) used to be an institutional playground — face values of ₹10 lakh or more kept out anyone without serious capital. That's no longer the barrier it once was. SEBI's Online Bond Platform Provider (OBPP) framework, in place since 2022 and tightened further since, now lets any retail investor buy the same listed debt for a few thousand rupees through a registered app. The mechanics are simple enough. The tax rules are where most first-time bond investors get caught out.

What an Online Bond Platform Actually Is

An Online Bond Platform Provider is a SEBI-registered entity — required to hold a stockbroker registration specifically for this business — that lets you browse, compare, and buy listed corporate bonds, NCDs, government securities, and other debt securities through a single app or website, instead of chasing individual issuers or wholesale desks. Platforms like IndiaBonds, GoldenPi, Wint Wealth, and a handful of others fall under this framework, and each is required to disclose yield, credit rating, issuer financials, and a standardised risk grading before you invest, rather than leaving that research entirely to you.

Listed vs Unlisted: The Distinction That Decides Your Tax Bill

This is the single most important thing to check before buying any bond or NCD, because it changes your tax outcome completely. A listed NCD trades on a recognised stock exchange and settles in your demat account; an unlisted NCD is placed privately and never trades on an exchange, even though it may still be registered with SEBI and rated by a credit agency. Retail-facing public issues are almost always listed within a few weeks of allotment specifically so retail investors get the more favourable tax treatment — but plenty of high-yield NCDs sold through wealth platforms and distributors are unlisted, and the yield pickup on offer often doesn't fully compensate for the harsher tax rules that come with it.

TDS on the Interest You Receive

Interest paid on corporate bonds and NCDs falls under Section 193 of the Income Tax Act, and an exemption that once let dematerialised, exchange-listed debentures escape TDS entirely was withdrawn by the Finance Act, 2023. Since then, a 10% TDS applies once your annual interest from a single issuer crosses ₹10,000, regardless of whether the NCD is listed and sitting in your demat account. This TDS isn't a final tax — it's adjustable against your total liability at filing time, and refundable if it exceeds what you actually owe — but it does mean cash gets withheld upfront on interest payouts, not just on redemption gains.

How Yields Are Quoted — and Why They Look High

Platforms typically display a Yield to Maturity (YTM) figure, which reflects the return if you buy at the current market price and hold to redemption, factoring in the coupon, any price premium or discount to face value, and the time left to maturity — not simply the coupon rate printed on the bond. A bond issued at a 9% coupon but trading below face value in the secondary market can show a YTM meaningfully higher than 9%, which is exactly why YTM, not coupon, is the number worth comparing against an FD rate. Credit rating matters just as much: an AA-rated NCD yielding 2-3% more than a government bond isn't free money — it's compensation for real default risk, and that gap should widen, not narrow, as the rating drops. One category deserves a separate check entirely: bank-issued AT1 perpetual bonds carry a similarly attractive coupon, but no maturity date and a discretionary, skippable interest payout — our AT1 perpetual bonds guide covers why these shouldn't be compared to a regular NCD on yield alone.

• Check whether the NCD is listed or unlisted before comparing yield — the tax difference can erase a meaningful part of the yield advantage on an unlisted issue.
• Look up the credit rating (AAA, AA, A, and below) from CRISIL, ICRA, or CARE on the platform's disclosure page, not just the headline yield.
• Confirm minimum investment size and lock-in, if any — most OBPP platforms now allow entry at ₹1,000-₹25,000 for a single bond, well below the older ₹10 lakh institutional threshold.
• Factor in the 10% TDS on interest above ₹10,000 a year from a single issuer when comparing net returns to a fixed deposit.

For the safest end of the debt spectrum, government-issued paper avoids the credit risk entirely — our guide to RBI Retail Direct covers how to buy G-Secs and T-Bills directly from the RBI at a similar ₹10,000 entry point, with sovereign rather than corporate credit risk. If you're weighing bonds against a mutual-fund wrapper instead of holding them directly, target maturity funds hold similar debt inside a fund structure with simpler, standard capital-gains taxation and built-in diversification across issuers.

The Bottom Line

SEBI's OBPP framework has genuinely opened corporate bond and NCD investing to retail investors who were priced out a few years ago, at ticket sizes that now compete directly with an FD. The platforms do the disclosure work — rating, YTM, issuer financials — but the tax outcome is still entirely on you to check: a listed NCD held over 12 months gets a real long-term concession, while an unlisted one never does, taxed at slab rate regardless of how long you hold it. Confirm listing status before you confirm the yield.
