5 Critical Differences: Convertible Notes vs. CCDs in 2025 (Tax Risks)

5 Critical Differences: Convertible Notes vs. CCDs in 2025 (Tax Risks)

If you are a DPIIT-recognised startup raising a bridge round of Rs. 25 lakh or more per investor, a Convertible Note is the faster, compliance-lighter path to closing. If your company lacks DPIIT status — or your investors need structured return mechanics that go beyond a simple discount — a Compulsorily Convertible Debenture (CCD) is your only compliant option. The five differences below determine your tax exposure, FEMA filing obligations, stamp duty cost, and cap table complexity for FY 2026-27 (AY 2027-28). Read this before you circulate a term sheet.

What These Instruments Actually Are

A Convertible Note (CN) is a debt instrument that a DPIIT-recognised startup issues to an investor, carrying an obligation to either convert into equity at the next qualified financing round or repay principal at maturity. Its legal basis sits within the Companies Act 2013 read with the DPIIT startup notification framework. Think of it as a handshake instrument: fast to issue, light on documentation, purpose-built for early-stage bridge rounds where neither party wants to fight over a pre-money valuation today.

A Compulsorily Convertible Debenture (CCD) is a debenture issued under the Companies Act 2013 that must convert into equity shares at or before a specified maturity date. It cannot be redeemed in cash — the clue is in the word "compulsorily." CCDs are available to any private limited company, require no DPIIT recognition, and can carry an interest coupon during the pre-conversion period. They offer richer contractual flexibility at the cost of higher compliance overhead.

Both instruments solve the same economic problem — deferring valuation until the next priced equity round — but through legally distinct structures that diverge sharply on regulatory eligibility, tax treatment, and practical execution.

Difference 1: Regulatory Source and Eligibility — DPIIT Gating Is Binary

Convertible Notes derive their legal legitimacy from the DPIIT Startup India notification read with the Companies (Acceptance of Deposits) Rules and related CBDT/FEMA circulars. The eligibility conditions are strict and non-negotiable:

• The company must hold a valid DPIIT recognition certificate (apply or verify at startupindia.gov.in)
• The company must have been incorporated not more than 10 years before the date of issue
• Annual turnover must not have exceeded Rs. 100 crore in any preceding financial year
• Each investor must invest a minimum of Rs. 25 lakh in a single tranche (as notified — confirm against the current DPIIT circular on the date of issuance)
• The instrument must be structured as a Convertible Note, not dressed up as an inter-corporate loan or NCD

If any single condition fails — your DPIIT certificate has lapsed, your turnover crossed the threshold in FY 2025-26, or the investor is putting in Rs. 20 lakh — you cannot legally issue a Convertible Note. Attempting to do so recharacterises the instrument as an unsecured loan or a deposit, triggering an entirely different compliance regime and potentially the Companies (Acceptance of Deposits) Rules 2014.

CCDs carry none of these preconditions. Any private limited company, at any stage, with any investor (subject to FEMA conditions for non-residents), can issue CCDs under Sections 42 and 71 of the Companies Act 2013. The instrument is governed by the Articles of Association, the CCD subscription agreement, and FEMA rules where foreign capital is involved.

Practical action: Verify your DPIIT certificate's validity on the portal on the day of execution — not when you started drafting the term sheet. DPIIT recognition can be cancelled or allowed to lapse without the company noticing. An investor who later discovers the CN was issued on lapsed recognition will have legitimate questions about the instrument's legal standing.

Difference 2: Tenure and Conversion Mechanics — Flexibility vs. Speed

Convertible Notes must be converted into equity or repaid within 10 years from the date of issue (this window was extended from the original 5-year cap). Conversion is typically tied to the "next qualified financing round" — defined by a minimum fundraise threshold agreed upfront. The economics are designed to be simple: a fixed discount to the next round price (15–25% is market standard) or a valuation cap, with the noteholder getting whichever produces more shares.

CCDs offer considerably more contractual range:

• Maturity tenures of up to 20 years are commercially common (the Companies Act does not prescribe a maximum for CCDs)
• Conversion formulas can incorporate IRR-based hurdles, revenue-linked ratchets, step-up conversion ratios on milestone failure, and sweep mechanisms tied to a deemed liquidation
• CCDs can carry an interest coupon during the pre-conversion period — 8–12% per annum is typical in current market; the rate is commercial and negotiated
• Conversion can trigger on a predetermined date, a fundraising event, a board-approved milestone, or even a change of control

The contractual richness of CCDs is also their documentation cost. A CCD subscription agreement with full conversion mechanics, a debenture certificate, board and shareholder resolutions, and the resulting ROC filings will consume 2–4 weeks of calendar time and meaningful legal fees. A Convertible Note using a market-standard template — and many exist now — can close in 3–5 business days.

Where this matters in practice: If your bridge investors are institutional — a family office seeking 18% IRR protection, a venture debt fund, or a foreign strategic with preferred return requirements — CCDs let you build those economics into the instrument. If your bridge is from angels who are backing you personally and simply want the most efficient path to your next equity round, Convertible Notes win on speed and simplicity every time.

Difference 3: Tax Treatment in 2026 — What Section 56(2)(viib) Still Means

This is the section founders most frequently misread, because the tax landscape shifted materially in 2024 and the full implications have not been widely digested.

The abolished provision: angel tax under Section 56(2)(viib)

Under the old law, if a closely held company issued shares — or instruments convertible into shares — at a price exceeding the fair market value (FMV) of those shares, the excess was taxable as "income from other sources" in the hands of the issuing company. This was the notorious angel tax. CCDs issued at inflated values were squarely in scope; Convertible Notes issued by DPIIT-recognised startups had a specific CBDT notification exemption.

Finance Act 2024 abolished Section 56(2)(viib) with effect from April 1, 2024. For all issuances from AY 2025-26 onwards — including the current AY 2027-28 — the company-side angel tax no longer exists for either instrument. This is settled law.

What the abolition does NOT eliminate

Section 56(2)(x) — the investor-side trap: If an investor receives CCDs or shares at a price below FMV (for example, through a conversion discount that is far steeper than market), the shortfall could be taxable in the investor's hands as income from other sources where the difference exceeds Rs. 50,000. Document your FMV computation at the time of conversion, not as an afterthought.

Capital gains on CCD conversion — Section 47(x): When CCDs convert to equity shares, Section 47(x) of the Income-tax Act 1961 treats the conversion as not a transfer — so no capital gains tax arises on the exchange itself. The investor's cost of acquisition of the new shares equals the cost of the CCDs. However, the holding period for LTCG eligibility restarts from the conversion date, not the CCD issuance date. Unlisted shares must be held for more than 24 months to qualify as long-term. An investor who received CCDs in August 2026 and converts in March 2028 must hold the resulting equity shares until at least March 2030 to access long-term capital gains rates. Investors who don't model this into their exit planning become unhappy cap table participants at the wrong moment.

The Convertible Note and the Section 47(x) gap — a live tax risk: Section 47(x) explicitly covers "bonds or debentures, debenture-stock or deposit certificates." A Convertible Note is not technically a debenture under the Companies Act. This creates a meaningful and currently unresolved tax risk: when a CN converts to equity, the conversion may constitute a taxable transfer in the investor's hands, with capital gains computed as the FMV of the shares received minus the cost of the Note. No CBDT clarification has squarely addressed this specific point as of the date of writing. Domestic investors funding a CN should obtain a written tax opinion before investing. For investors resident in a tax treaty country, treaty relief may be available — but do not assume it.

Interest on CCDs is ordinary income: If your CCDs carry a 9% coupon, that interest accrues as taxable income in the investor's hands (as "income from other sources") in the year it is paid or credited. The company is entitled to a deduction under Section 36(1)(iii) provided the borrowing is for business purposes — which it will be for a genuine bridge round deployed into operations. Do not let unpaid interest accrue informally; document each accrual period clearly.

Difference 4: FEMA Compliance and Foreign Investment Rules

Both instruments can accept foreign capital, but the regulatory pathway and risk profile differ.

CCDs with foreign investment are classified as equity instruments under the Foreign Exchange Management (Non-debt Instruments) Rules, 2019 (NDI Rules). This brings several implications:

• CCDs count against FDI sectoral caps and must follow the applicable entry route — automatic or government approval
• The issue price must comply with RBI pricing guidelines: broadly, not less than the FMV of shares as per an internationally accepted methodology (DCF or comparable companies) at the time of issue
• Form FC-GPR must be filed through the RBI's FIRMS portal within 30 days of allotment
• An Annual Return on Foreign Liabilities and Assets (FLA Return) must be filed by July 15 of each financial year in which a foreign liability exists
• At conversion, the conversion price must also comply with pricing guidelines prevailing on that date — a second pricing event your legal counsel must flag

Convertible Notes with foreign investment are permitted only in DPIIT-recognised startups, under a specific carve-out in the NDI Rules. The regulatory concession is meaningful: no FMV test applies at the time of CN issuance — the face value of the note is the issue price. At conversion, however, the shares must be issued at a price compliant with then-applicable FDI pricing guidelines. FC-GPR within 30 days and the annual FLA return both apply equally.

The sectoral test that kills deals late: Both instruments carry the risk that your sector is under the government approval route or has FDI percentage caps. A DPIIT-recognised fintech startup in a payments sub-sector may still require RBI approval for foreign CN investment depending on the nature of its operations. Test the sectoral classification against the current FDI Policy before the term sheet stage, not during the FC-GPR filing.

Difference 5: Cap Table Impact and Compliance Overhead

For a founder trying to close in under two weeks and keep the cap table clean for a Series A, this difference is the most operationally consequential.

Convertible Notes require:

• A board resolution approving the issuance — typically no shareholder resolution required for DPIIT-compliant CNs
• A Convertible Note subscription agreement (a standard template instrument)
• No charge creation, no debenture trustee, no debenture certificate
• Form PAS-3 (return of allotment) filed with the ROC within 30 days of allotment
• Stamp duty on the instrument at applicable state rates under the Indian Stamp Act 2020 — confirm with the execution state before signing

CCDs require (for an unsecured CCD — the standard startup structure):

• Board resolution and, frequently, a shareholder special resolution if the CCDs exceed the limit contemplated in the Articles or if authorised capital needs enhancement
• A detailed CCD subscription agreement plus individual debenture certificates
• Form PAS-3 within 30 days and Form MGT-14 within 30 days of the special resolution
• Stamp duty on the debenture instrument — typically higher per rupee than a simple note instrument; confirm state-specific rates
• If the CCDs are secured: Form CHG-1 for charge creation within 30 days of creation of the charge; a mandatory debenture trustee appointment under Companies (Share Capital and Debentures) Rules 2014

On the cap table, CCDs appear as outstanding convertible instruments with accrued interest. A Series A lead will model the dilution from CCD conversion precisely — including interest that has been accruing. If your CCDs carry a 20% discount and 10% annual interest that has been accruing for 18 months on a Rs. 1 crore bridge, the effective conversion produces materially more shares than the headline discount suggests. That dilution calculation belongs in your data room, not in a surprise conversation during term sheet negotiations.

Worked Example: Rs. 75 Lakh Bridge Round — CN vs. CCD Side by Side

Scenario: TechFlow Private Limited, a DPIIT-recognised B2B SaaS startup, needs Rs. 75 lakh in bridge capital in August 2026 from three investors — two domestic angels (Rs. 25 lakh each) and one NRI investor (Rs. 25 lakh).

Option A: Convertible Notes

• Eligibility: DPIIT recognition valid ✓; FY 2025-26 turnover Rs. 18 crore ✓; each tranche Rs. 25 lakh ✓
• Documentation: Three CNs under a standard subscription agreement; single board resolution; Form PAS-3 by mid-September 2026
• FEMA: Form FC-GPR on the FIRMS portal for the NRI's Rs. 25 lakh within 30 days of allotment; annual FLA return by July 15, 2027
• Interest accrual: Nil (CNs carry no coupon)
• Conversion at Series A (assumed December 2027, Rs. 10 crore raise at Rs. 200 per share): Notes convert at 20% discount → Rs. 160 per share → each investor receives 15,625 shares (Rs. 25 lakh ÷ Rs. 160)
• Total new shares from bridge: 46,875 shares across three investors
• Legal and compliance cost estimate: Rs. 30,000–50,000
• Time to close: 5–7 business days

Option B: CCDs (same investors, but TechFlow hypothetically lacks DPIIT recognition)

• Documentation: CCD subscription agreement, three debenture certificates, board resolution, special resolution, Form PAS-3 + Form MGT-14
• Interest at 9% p.a. on Rs. 75 lakh over 16 months (August 2026 to December 2027): Rs. 9,00,000 accrued interest — taxable in investors' hands as income from other sources; deductible for TechFlow under Section 36(1)(iii)
• Conversion mechanics: CCDs convert at the lower of (i) 20% discount to Series A price = Rs. 160 per share, or (ii) an agreed valuation cap. The Rs. 9 lakh accrued interest either converts into additional shares (approx. 5,625 additional shares at Rs. 160) or is settled in cash — this must be agreed in the subscription agreement, not at conversion
• Total dilution: ~52,500 shares (vs. 46,875 under Option A) — a difference of 5,625 shares arising purely from interest accrual, equivalent to roughly 0.5–0.8% incremental dilution depending on total share capital
• Stamp duty: State-specific under Indian Stamp Act 2020; can range from Rs. 3,750 to meaningfully higher depending on execution state
• Legal and compliance cost estimate: Rs. 1,20,000–2,00,000
• Time to close: 15–25 business days
• Section 47(x) protection: Available on conversion — no capital gains on exchange of CCDs for shares; holding period for LTCG starts December 2027

The net delta: For the same Rs. 75 lakh bridge, Option A saves Rs. 70,000–1,50,000 in execution costs, closes 2–3 weeks faster, generates zero interest accrual, and avoids the Section 47(x) uncertainty on Convertible Notes (which is a risk to investors, not the company). Option B produces a richer contractual structure but at a measurable cost in time, money, and future cap table complexity.

Common Mistakes Founders Make — and How to Fix Them

1. Issuing a CN after DPIIT recognition has quietly lapsed Recognition can be cancelled or allowed to expire without the founders noticing — particularly in companies past their third year that have not renewed engagement with DPIIT. A CN issued on lapsed recognition is not a legal Convertible Note; it is an unsecured loan that may violate the Companies (Acceptance of Deposits) Rules 2014. Fix: Log in to the DPIIT portal and confirm active recognition status on the day of execution. Screenshot and retain the confirmation.

2. Treating CCD interest as equity because "it'll all convert anyway" Interest on CCDs accrues as debt until the moment of conversion. If your agreement is silent on what happens to accrued interest at conversion, the investor may demand cash settlement. Fix: Address the interest treatment explicitly in the subscription agreement — whether it converts to equity at the applicable conversion price or is forgiven or paid in cash. Model it in your cap table from day one.

3. Missing the 30-day FC-GPR window for foreign investment Form FC-GPR through the FIRMS portal is mandatory within 30 days of allotment for any foreign or NRI investment in either CNs or CCDs. Late filing attracts compounding penalties under FEMA. Fix: Treat FC-GPR as part of the closing checklist, not a post-closing administrative item. The process should begin the week of allotment.

4. Assuming Section 47(x) protects Convertible Note investors Section 47(x) covers bonds and debentures — not notes. Domestic investors converting a CN into equity may face a capital gains event at conversion. Do not represent otherwise to investors without a formal tax opinion. Fix: Flag this risk in the investment disclosure at the time of CN issuance; ensure investors seek their own tax advice.

5. Ignoring the holding period reset on CCD conversion An investor who holds CCDs for 20 months before conversion does not carry that holding period forward to the resulting equity shares. The 24-month LTCG clock for unlisted shares restarts on the date of conversion. Investors who plan to exit shortly after conversion will face short-term capital gains rates. Fix: Build the expected conversion timeline into your investor communications so there are no surprises at exit.

Key Takeaways

• DPIIT recognition is a binary gate: No valid certificate on the date of issuance means no Convertible Note — regardless of how the instrument is labelled.
• Section 56(2)(viib) is abolished from April 1, 2024, but Section 56(2)(x) (investor-side below-FMV receipts) and the Section 47(x) gap for Convertible Notes are live tax risks that need specific professional advice.
• CCDs offer contractual flexibility — interest coupons, IRR floors, formula-based conversion triggers — but cost more to execute, take longer to close, and create accrued debt that inflates cap table dilution if not tracked.
• Both instruments require FC-GPR within 30 days for any foreign or NRI investor component; missing this deadline triggers compounding FEMA penalties.
• The LTCG holding period resets at conversion for CCD investors — structure your bridge timeline with your investors' exit horizon in mind, not just your own fundraising calendar.
• The Section 47(x) gap is the most underappreciated risk in Convertible Note financings: domestic angel investors funding CNs should obtain a written tax opinion before signing; the company should not make representations about the taxability of conversion.
• For most angel-backed DPIIT startups, a Convertible Note remains the right instrument — faster, cheaper, and simpler to explain in a Series A data room. Reach for CCDs only when DPIIT eligibility is absent, investor economics require structured returns, or the bridge tenure extends beyond 10 years.
