On 27 May 2026, the Ministry of Corporate Affairs did something the Social Stock Exchange had been waiting on since 2022: it made subscribing to a zero coupon zero principal instrument a statutorily recognised CSR activity. Two gazette notifications — G.S.R. 415(E) and G.S.R. 416(E) — inserted a new Rule 4A into the Companies (CSR Policy) Rules, 2014, and added item (xiii) to Schedule VII of the Companies Act: subscription to zero coupon zero principal instruments on Social Stock Exchange.
Until that morning, a company that wanted to fund an SSE-listed non-profit had a genuine legal question on its hands — does buying a security that pays no interest and returns no principal count as CSR under Section 135? Boards, quite reasonably, waited. That question is now closed. What is left is execution, and that is what this guide covers.
What Rule 4A actually says
The rule is short. Five provisions carry all the weight.
A company may carry out CSR activities through a zero coupon zero principal instrument issued by a Not for Profit Organisation registered with the Social Stock Exchange segment of a recognised stock exchange. NPO here takes its meaning from Regulation 292A of SEBI's ICDR Regulations, so the corporate-law and securities-law definitions now line up.
The expenditure is capped at 10% of the company's total CSR expenditure for that financial year. This is a per-year ceiling, not a cumulative one, and it signals intent clearly: the SSE route supplements your existing implementation channels, it does not replace them.
A company that subscribes to a ZCZP is exempt from undertaking impact assessment of any project funded through it. More on why this matters below.
The obligations then shift to the issuing NPO. It must complete the funded project within three succeeding financial years from the date of issue. And when the instrument's listing terminates, any unspent amount goes to a fund specified under Schedule VII — the PM's National Relief Fund and similar — with a compliance report filed to SEBI. The money cannot sit with the NPO indefinitely.
Finally, the existing Rule 4 continues to apply to CSR done this way, except sub-rules (5) and (6). Your CSR committee processes, board oversight and annual reporting obligations do not change because the money moved through an exchange.
Why a CFO should actually care
The impact assessment exemption is the headline for larger companies. Under Rule 8(3), a company with an average CSR obligation of ₹10 crore or more must commission independent impact assessments for projects of ₹1 crore and above — a real cost, and a recurring one. Route that project through a ZCZP subscription instead and the requirement falls away. It falls away because the work does not disappear; it moves. SSE-listed NPOs must file annual impact reports audited by a social impact assessor under SEBI's framework, along with annual disclosures on fund utilisation. You are substituting your own commissioned assessment with a regulator-mandated, exchange-supervised disclosure regime that someone else prepares and files.
The second thing worth caring about is the audit trail. A ZCZP subscription is a demat security allotted through an exchange process, with a fund-raising document reviewed by the SSE, a registrar, and ISINs from the depositories. When your statutory auditor or an MCA inquiry asks where the CSR money went, the paper answers itself. Compare that with the documentation burden of a bespoke implementing-agency arrangement.
The third is portfolio thinking. India's total CSR spend was ₹34,909 crore in FY24 per MCA data. The 10% cap means roughly ₹3,500 crore a year could, in principle, flow through the SSE nationally. For your own numbers: a company with a ₹20 crore obligation can put up to ₹2 crore a year into ZCZP subscriptions — enough to fund one meaningful listed project annually while the remaining 90% runs through your established channels.
The mechanics, end to end
The process is closer to a public-issue subscription than to a grant disbursement, which is exactly the point.
Policy and approvals. Check whether your board-approved CSR policy and annual action plan accommodate the ZCZP route; most policies written before May 2026 will not mention it. The CSR committee recommends, the board approves, same as any other CSR activity.
Screen live issues. Both NSE and BSE run SSE segments. Look for NPOs with open or upcoming ZCZP issues, and read the fund-raising document the way you would read an offer document — project scope, per-unit costing, governance, past impact reports.
Subscribe. ZCZPs are demat-only and non-transferable. The minimum issue size is ₹50 lakh and the minimum application is ₹1,000, so ticket size is not a constraint at either end. Applications run through the standard exchange process.
Allotment and records. The instrument sits in your demat account at zero value — it is expenditure, not an investment, and your books should treat it that way.
Report. The subscription is disclosed in the board's annual CSR report within the 10% ceiling, alongside your other CSR spend.
One timing note: SEBI's April 2026 circular lets an issue proceed at 50% subscription (down from the default 75%) where the SSE has done prior due diligence on per-unit deliverable projects. Practically, this means more issues will close successfully — but also that the project you fund may run at a reduced scale, which is worth reading for in the fund-raising document's subscription scenarios.
What to watch
The cap is annual, so multi-year commitments need to be structured as fresh subscriptions each year, each inside that year's 10%. The three-financial-year completion condition sits on the NPO, but it shapes your selection: this route suits discrete, time-bound projects, not open-ended programmes. There is no secondary market and no exit — you are spending, not parking. And the rule is five weeks old; the first annual filings under it have not happened, so document your reasoning generously and let your tax advisor confirm treatment, which the amendment does not change.
None of this is complicated. But it is new, and the companies that move early will be choosing from the current, thin pool of listed issuers — which is also why NPOs are now racing to register. If your CSR committee wants a screened shortlist of SSE-registered NPOs matched to your Schedule VII focus areas, or a review of your CSR policy language before the board signs off on the route, that is exactly the work we do.
