The Complete Step-by-Step Guide

Before You Click "Buy": Quick Checklist

✓ PAN card, matching your bank account name exactly ✓ An active demat account (mandatory for most corporate bond routes) ✓ Aadhaar-linked mobile number for KYC verification ✓ A bank account for settlement ✓ The bond's ISIN, credit rating, and YTM checked, not assumed ✓ Minimum investment amount confirmed, since this varies far more than government bonds

If you've bought a government bond before, corporate bonds will feel familiar in some ways and genuinely different in others. This guide walks through exactly where those differences matter.

If you're new to bond investing, start with our How to Invest in Bonds in India: Step-by-Step guide to understand the basics before choosing a corporate bond.

How do you buy corporate bonds in India? You can buy corporate bonds through three main routes: SEBI-registered online bond platforms (OBPPs), the primary market during a public NCD issue, or the secondary market via NSE/BSE using a demat account. Unlike government bonds, corporate bonds require you to evaluate the issuer's credit rating and financial health yourself, since there's no sovereign guarantee behind the repayment.

Buying Corporate Bonds: At a Glance

• Primary requirement: Active demat account (mandatory for secondary market and most primary issues)
• Minimum investment: Varies often ₹1,000-10,000 on OBPPs, sometimes higher for institutional-style issuances
• Cost to you: Brokerage varies by platform; many OBPPs now offer zero-commission access
• What you need: PAN, demat account, bank account, and critically the discipline to check the credit rating before the yield
• Settlement: Typically T+1 through exchanges
• Who can buy: Any resident Indian individual with a functioning demat account; NRIs through specific permitted routes

Corporate Bonds vs Government Bonds: Why the Buying Process Actually Differs

Before the how-to, one distinction that changes everything downstream: government bonds carry a sovereign guarantee, so the entire buying process is designed around convenience RBI Retail Direct, no credit analysis required, non-competitive bidding that removes the guesswork.

Corporate bonds don't have that guarantee. The company itself is your counterparty, not the government. Which means the buying process has to include a step government bonds never asked of you: evaluating whether this specific company can actually repay you.

That's not a footnote. It's the entire reason this guide looks different from the government bonds one.

Route 1: SEBI-Registered Online Bond Platforms (OBPPs)

This is the route most retail investors use today, and it's the one built specifically for individual investors rather than institutions.

Step-by-step

1. Choose a SEBI-registered Online Bond Platform Provider (OBPP). These platforms are specifically regulated by SEBI to distribute bonds to retail investors, and you can verify any platform's registration status on SEBI's official website before proceeding.

2. Complete your KYC. Upload your PAN, and complete Aadhaar-based e-KYC or video KYC, depending on the platform's process.

3. Link your demat account. Most OBPPs require this upfront, since corporate bonds are held in dematerialized form, similar to shares. If you don't have one, several platforms guide you through opening one during onboarding.

4. Link your bank account for order settlement.

5. Browse available bonds, filtering by credit rating, yield, tenure, and issuer type (NBFC, housing finance, corporate). This is where the real decision-making happens more on exactly what to check below.

6. Review the offer document or information memorandum for your chosen bond. Yes, actually open it. This document contains the credit rating rationale, security structure, and specific terms that a summary card on the app won't fully capture.

7. Place your order, specifying the amount you want to invest.

8. Funds are debited, typically settling T+1.

9. The bond is credited to your demat account, where you can track it alongside your other holdings.

Common mistake: Skipping the offer document because the platform's summary page already shows the yield and rating. The offer document is where you'll find whether the bond is secured or unsecured, and what "secured" actually means for that specific issuer details that materially change your risk if something goes wrong.

Route 2: Buying During a Primary NCD Public Issue

Companies periodically raise money by issuing Non-Convertible Debentures (NCDs) directly to the public, similar in structure to an IPO.

What this looks like in practice:

1. Track upcoming NCD issues through your broker, an OBPP, or financial news sources covering primary bond issuances.
2. When an issue opens, review the prospectus. This is a more detailed regulatory document than a typical OBPP listing, since it's a fresh public offering.
3. Apply through your broker's platform, an OBPP facilitating the issue, or via ASBA (Application Supported by Blocked Amount) through your bank, similar to an IPO application.
4. If allotted, the bond is credited to your demat account after the issue closes, typically listing on the exchange shortly after.

Why this route matters: buying in the primary issue means you're getting the bond at face value, before any secondary market price movement. If the issue is oversubscribed, allotment may be proportionate rather than guaranteed in full, a detail specific to primary issues that doesn't apply to routine OBPP purchases of already-listed bonds.

Route 3: Buying Through the Secondary Market (NSE/BSE)

If you want a specific bond that isn't part of a current OBPP listing or live NCD issue, the secondary market is where already-issued bonds trade.

What you need:

• An active demat account with a registered broker
• A trading account linked to that demat account

The process:

1. Log into your broker's trading platform.
2. Search for the specific corporate bond by ISIN or issuer name.
3. Check the current market price and yield to maturity not just the coupon. Secondary market corporate bonds can trade meaningfully above or below face value.
4. Place a buy order, similar to buying a stock.
5. Settlement typically follows T+1.

Two details that catch secondary-market buyers off guard:

You may pay more than the quoted price due to accrued interest the interest accumulated since the bond's last coupon date, which gets added to your settlement amount and is owed to the seller. This is worth watching closely in the secondary market specifically, since it's easy to mistake for a pricing error when it's actually a routine part of settlement.

Corporate bond liquidity varies far more than government bonds. Some listed corporate bonds trade thinly, meaning you might not find a buyer or seller instantly at a fair price worth checking trading volumes before assuming you can exit whenever you choose.

Comparing the Three Routes

What to Actually Check Before You Buy Any Corporate Bond

This is the section that separates an informed corporate bond investor from someone who bought because a number looked attractive. Skipping it is where real losses happen.

The credit rating, and the modifier. AA+ and AA− are not the same risk. Check the rating from CRISIL, ICRA, CARE, or India Ratings and specifically look at the modifier, not just the letter.

The outlook, not just the rating. A rating comes attached to an outlook Stable, Positive, or Negative. A Negative outlook can be an early warning sign before an actual downgrade happens, and it's worth reading even when the letter rating itself looks reassuring.

Secured vs unsecured. A "secured" bond means specific assets back your claim if the issuer defaults. An unsecured bond means you're an unsecured creditor, behind secured creditors in any recovery process. This single word changes your actual risk more than most other details combined.

The credit spread. The extra yield a corporate bond offers over a comparable government bond is called the credit spread, and it exists specifically to compensate you for the additional risk the market has priced in. A wider spread usually means the market sees more risk worth asking why, rather than just taking the higher number.

The issuer's business, in plain terms. What does this company actually do? Is it a well-established NBFC with a long operating history, or a newer entrant offering a higher yield specifically because the market hasn't fully priced its risk yet?

Yield to maturity, not coupon. Especially in the secondary market, the price you pay determines your real return; the coupon printed on the bond is only the starting point.

Interest payment frequency. Most listed corporate bonds pay interest quarterly, semi-annually, or annually, depending on the specific issue worth checking if you're relying on the bond for regular income.

Tenure and your own liquidity needs. Corporate bonds, especially in the secondary market, can have thinner trading volumes than government bonds. Don't commit money you might need before maturity to a bond you're not confident you can exit early.

Call and put options, if any. Some corporate bonds include clauses letting the issuer redeem early (call option) or letting you exit early under specific conditions (put option). These materially affect your actual holding period and should never be assumed away.

After You Buy: Ratings Aren't a One-Time Check

Even highly rated issuers can be downgraded over time as their financial position changes a rating reflects a point in time, not a permanent guarantee. Monitoring your bond's rating and outlook after purchase matters just as much as checking it before you buy, especially for longer-tenure holdings.

Taxation: What Happens After You Buy

Interest income from most corporate bonds is taxed at your individual income tax slab rate, similar to government bonds and bank FDs. There's typically no special concessional rate for standard corporate bond interest.

For bonds held in demat form and listed on an exchange, TDS is generally not deducted for resident individual investors but you're still required to self-report and pay tax on the interest earned in your annual return. If you sell a bond in the secondary market before maturity, any gain or loss may be evaluated separately depending on your holding period.

Given how much tax treatment can vary by bond structure and individual circumstance, this is genuinely worth confirming with a tax advisor before committing significant capital, rather than relying on any single guide.

Mistakes First-Time Corporate Bond Buyers Actually Make

Chasing yield without checking why it's high. A 12% coupon isn't generosity, it's compensation for risk the market has already priced in. Find out what that risk is before you find out the hard way.

Treating "secured" as a synonym for "safe." Secured bonds still carry credit risk. The security just improves your recovery odds if things go wrong it doesn't prevent things from going wrong.

Not reading the offer document. The platform summary tells you the headline numbers. The offer document tells you the actual terms, and it's the only place some critical details like call options or specific security structure will actually be spelled out.

Ignoring liquidity before committing. Some corporate bonds trade thinly. If you might need this money before maturity, check trading volumes, not just the yield, before you buy.

Assuming all OBPPs list the same bonds at the same terms. Availability and presentation can differ meaningfully across platforms worth comparing before defaulting to the first one you open.

Checking the rating once, then forgetting about it. A rating at purchase isn't a rating for life. Revisit it periodically, especially for longer-tenure bonds.
