Why this chapter matters in CS Professional
This chapter's single highest-risk fact is also its most current-events-adjacent one: a widely reported pending Bill would raise the CSR profit threshold, but it is not yet law, and stating it as current would be a direct factual error in a live exam.

Board Governance, Committees and Business Ethics (earlier chapter in this subject)
This chapter continues Paper 1's governance-and-responsibility content into stakeholder-facing obligations.

CSR, Stakeholder Engagement and ESG Investing

Part B of Paper 1 moves from governance structure into a company's obligations toward stakeholders beyond its shareholders — Corporate Social Responsibility under Section 135, and the broader landscape of stakeholder engagement and ESG-linked investing. As with the previous chapter, precision on current figures matters here specifically because one of this topic's most consequential numbers is currently the subject of a pending, not-yet-enacted amendment — and confusing "proposed" with "current" is this chapter's single biggest risk.

1. CSR applicability under Section 135

Section 135(1) of the Companies Act makes CSR obligations mandatory for any company meeting any ONE of three thresholds in the immediately preceding financial year: net worth of ₹500 crore or more, turnover of ₹1,000 crore or more, or net profit of ₹5 crore or more. Meeting even one of these three thresholds is sufficient — a company does not need to cross all three.

A qualifying company must spend at least 2% of its average net profit of the preceding three financial years on CSR activities.

A Corporate Laws (Amendment) Bill, 2026 has proposed raising the net-profit threshold from ₹5 crore to ₹10 crore (leaving the net-worth and turnover thresholds unchanged) — the Bill was reported by a Joint Parliamentary Committee in August 2026 broadly endorsing it, but had not been enacted as of this content's most recent review, so the current, legally applicable net-profit threshold remains ₹5 crore.

A candidate should state the current ₹5 crore figure as the operative law, mentioning the ₹10 crore proposal only as a clearly-labelled pending change.

2. The CSR Committee and the small-obligation exception

A qualifying company must constitute a CSR Committee of at least three directors, including at least one independent director (subject to relaxations for companies not otherwise required to have an independent director).

Section 135(9) provides a specific exception: where a company's CSR spending obligation does not exceed ₹50 lakh, the company is not required to constitute a separate CSR Committee at all — the board itself directly discharges the committee's functions.

This ₹50 lakh exception does not apply, however, to a company that has unspent CSR money sitting in its Unspent CSR Account for an ongoing project — such a company must still constitute the committee regardless of whether its total obligation is below ₹50 lakh.

Schedule VII lists the permitted categories of CSR activity — spanning hunger, poverty, health and sanitation; education; gender equality and women's empowerment; environmental sustainability; protection of national heritage, art and culture; benefits to armed forces veterans and war widows; sports promotion; contributions to the PM's National Relief Fund, PM CARES Fund and other specified central funds; contributions to Central-Government-approved incubators and to R&D in science, technology, engineering and medicine; rural development; slum development; and disaster management (relief, rehabilitation and reconstruction).

3. Unspent CSR amounts — two different timelines for two different situations

A company that has not spent its full CSR obligation in a given year faces two different treatment tracks, depending on whether the unspent amount relates to an "ongoing project."

SituationTimeline
Unspent amount relating to an ongoing projectTransferred within 30 days of financial-year-end to a separate "Unspent CSR Account"; must be spent within 3 financial years of transfer; if still unspent after 3 years, transferred to a Schedule VII fund within a further 30 days
Unspent amount NOT relating to an ongoing projectTransferred directly to a specified Schedule VII fund (such as PM CARES) within 6 months of financial-year-end

Failure to transfer within the applicable timeline attracts a penalty of the lower of twice the shortfall amount or 10% of the amount required to be transferred — a specific, precise formula worth stating exactly rather than describing loosely as "a penalty."

4. Business Responsibility and Sustainability Reporting (BRSR)

BRSR is mandatory for the top 1,000 listed companies by market capitalisation, applicable from FY 2022-23 onward, and voluntary for other listed companies. It is structured around the 9 principles of the National Guidelines on Responsible Business Conduct (NGRBC), covering roughly 140 data points across essential and leadership indicators spanning environmental, social and governance performance.

A separate, phased assurance requirement — BRSR Core — applies specifically to a defined set of BRSR's key performance indicators, phased in by market-capitalisation rank: the top 150 entities from FY 2023-24, the top 250 from FY 2024-25, the top 500 from FY 2025-26, and the top 1,000 from FY 2026-27 — meaning the widest tier of this phase-in is now live for the current financial year, not merely an announced future requirement.

A subsequent SEBI circular softened the original mandate somewhat, allowing companies to choose between reasonable assurance and a third-party assessment against Industry Standards Forum-developed benchmarks for this same core data.

Worked Examples

Example 1. A company has a net worth of ₹300 crore, a turnover of ₹1,200 crore, and a net profit of ₹3 crore in the immediately preceding financial year. Is it subject to Section 135's CSR obligations?

Yes — meeting any ONE of the three thresholds is sufficient, and this company's turnover of ₹1,200 crore exceeds the ₹1,000 crore threshold, even though its net worth and net profit fall below their respective thresholds.

Example 2. A candidate states in an answer that the current CSR net-profit threshold is ₹10 crore. Evaluate this statement.

This is incorrect as a statement of current law. The ₹10 crore figure is only a proposal under the Corporate Laws (Amendment) Bill, 2026, which had not been enacted as of this content's most recent review — the current, legally applicable net-profit threshold remains ₹5 crore.

Example 3. A company's total CSR obligation for the year is ₹40 lakh, and it has no unspent amount from any ongoing project carried forward from a prior year. Is it required to constitute a separate CSR Committee?

No — since its CSR obligation does not exceed ₹50 lakh and it has no unspent ongoing-project amount, Section 135(9)'s exception applies, and the board itself can directly discharge the CSR Committee's functions without constituting a separate committee.

Example 4. The same company from Example 3, in a later year, has an unspent amount of ₹8 lakh sitting in its Unspent CSR Account relating to an ongoing project, even though its total current-year obligation is still only ₹35 lakh. Does the ₹50 lakh exception still apply?

No — the ₹50 lakh exception does not apply to a company with unspent CSR money in its Unspent CSR Account for an ongoing project, regardless of how small its total obligation is; this company must constitute a CSR Committee despite its low overall obligation.

Example 5. A company has ₹12 lakh of unspent CSR money relating to an ongoing project at the end of its financial year (31 March). By what date must this amount be transferred to the Unspent CSR Account, and within what further period must it actually be spent?

It must be transferred to the Unspent CSR Account within 30 days of financial-year-end (by around 30 April), and must be spent within 3 financial years of that transfer.

Example 6. A company has ₹5 lakh of unspent CSR money that does NOT relate to any ongoing project. What is the applicable transfer timeline, and how does it differ from the ongoing-project timeline?

It must be transferred directly to a specified Schedule VII fund (such as PM CARES) within 6 months of financial-year-end — a single, direct transfer, unlike the ongoing-project route's two-stage process (30-day transfer to an Unspent CSR Account, then up to 3 years to actually spend it).

Example 7. A listed company ranks 800th by market capitalisation for the financial year 2026-27. Is it within the current BRSR Core assurance requirement's coverage for that year?

Yes — the BRSR Core assurance requirement's phase-in reached the top 1,000 listed entities by market capitalisation from FY 2026-27, so a company ranked 800th falls within that current coverage.

Summary

Section 135's CSR obligation applies to any company meeting any one of three thresholds (₹500 crore net worth, ₹1,000 crore turnover, or ₹5 crore net profit — currently, pending an as-yet-unenacted proposal to raise the profit figure to ₹10 crore), requiring 2% of average net profit of the preceding three years to be spent, with a CSR Committee mandatory except for the Section 135(9) small-obligation exception (₹50 lakh or below, unless unspent ongoing-project money is involved).

Unspent CSR amounts follow two distinct timelines — 30 days to an Unspent CSR Account then up to 3 years to spend for ongoing projects, versus a direct 6-month transfer to a Schedule VII fund for non-ongoing-project amounts — with a lower-of-2x-shortfall-or-10% penalty for missing the applicable timeline.

BRSR is mandatory for the top 1,000 listed companies from FY 2022-23, structured around the 9 NGRBC principles, with a separately phased BRSR Core assurance requirement that reached the full top-1,000 tier from FY 2026-27 — a currently live requirement, not a future one.

Traps CS Professional sets — and how to dodge them

These are the exact option-traps and misreads that cost marks under negative marking.

WATCH OUT
Stating the current CSR net-profit threshold as Rs. 10 crore
State the current, still-applicable figure of Rs. 5 crore, mentioning the Rs. 10 crore proposal only as a pending, not-yet-enacted Bill.
Why it happens: This is the chapter's single highest-risk factual error, since the proposal is widely reported but genuinely not yet law.
WATCH OUT
Applying the Section 135(9) small-obligation exception without checking for unspent ongoing-project money
Always check separately whether the company has any unspent CSR amount for an ongoing project — if so, the exception does not apply regardless of how small the current obligation is.
Why it happens: This ongoing-project carve-out is a specific, frequently tested qualification to the headline Rs. 50 lakh exception.
WATCH OUT
Citing a 5-year timeline for ongoing-project unspent CSR amounts
State the correct 3-year timeline for spending money transferred to the Unspent CSR Account, with a further 30 days to transfer any still-unspent balance to a Schedule VII fund after that.
Why it happens: The 5-year figure is a commonly confused error; the correct figure is 3 years, not 5.

5-minute revision

The whole chapter, distilled. Read this the night before the exam.

  • Section 135(1): net worth >= Rs. 500cr OR turnover >= Rs. 1,000cr OR net profit >= Rs. 5cr (any ONE) triggers CSR; Rs. 10cr profit threshold is PROPOSED (Corporate Laws Amendment Bill 2026), NOT enacted.
  • CSR spend: >= 2% of average net profit of preceding 3 financial years.
  • CSR Committee: min 3 directors incl. >=1 independent; Section 135(9) exception at <= Rs. 50 lakh obligation UNLESS unspent ongoing-project money exists.
  • Schedule VII: hunger/poverty/health, education, gender equality, environment, heritage, armed forces veterans, sports, PM relief funds, incubators/R&D, rural/slum development, disaster management.
  • Unspent CSR (ongoing project): 30 days -> Unspent CSR Account -> 3 years to spend -> 30 more days to transfer to Schedule VII fund if still unspent.
  • Unspent CSR (non-ongoing): 6 months direct transfer to Schedule VII fund.
  • Penalty for missed timeline: lower of (2x shortfall) or (10% of amount required to be transferred).
  • BRSR: top 1,000 by mcap, mandatory from FY 2022-23, 9 NGRBC principles, ~140 data points.
  • BRSR Core assurance glide path: top 150 (FY23-24) -> top 250 (FY24-25) -> top 500 (FY25-26) -> top 1,000 (FY26-27, current).

Prep strategy
  • First pass: memorise the three Section 135(1) thresholds and explicitly note the Rs. 5cr-vs-proposed-Rs.10cr distinction as a standalone flashcard.
  • Second pass: build the unspent-CSR decision tree (ongoing project? -> which timeline) as a flowchart, since scenario questions test this directly.
  • Third pass: memorise the BRSR Core glide-path table (150/250/500/1,000 by FY) to answer any current-coverage question precisely.

Exam-hall strategy

Battle-tested tips from mentors and toppers for this topic under the sectional clock.

  1. Always check Section 135 applicability against all three thresholds independently, since meeting just one is sufficient — don't assume a company failing one threshold is automatically exempt.
  2. For any CSR net-profit-threshold question, explicitly state the current Rs. 5 crore figure and flag the pending Rs. 10 crore proposal as not yet law, rather than picking one number silently.
  3. For unspent-CSR questions, always identify first whether the amount relates to an ongoing project, since that single fact determines which of the two entirely different timelines applies.
  4. For BRSR/BRSR Core questions, state the company's market-capitalisation rank against the current phase-in tier explicitly, rather than a general 'large companies must comply' answer.

Beyond the exam

Where this skill shows up in the job you're competing for — and in life.

CSR compliance and unspent-fund tracking

Correctly classifying unspent CSR amounts as ongoing-project or non-ongoing-project, and tracking the resulting transfer deadlines, is routine, high-stakes compliance work with real financial penalties for error.

ESG and BRSR reporting advisory

Advising a large listed company on its current BRSR and BRSR Core obligations, correctly identified by its market-capitalisation rank for the relevant financial year, is directly operational Professional-level Company Secretary work.

Questions aspirants ask

Pulled from the Q&A community and mentor sessions.

It would become outdated once the Bill is actually enacted and notified — this chapter explicitly flags the proposal so a candidate knows to verify the current applicable figure against the latest Companies Act text before an exam attempt, rather than treating either figure as permanently fixed.

No — the board itself directly discharges the CSR Committee's functions in that situation; the exception removes the need for a separate committee, not the underlying CSR governance and spending obligations themselves.

Once a company falls within the current BRSR Core assurance population by its market-capitalisation rank, the assurance requirement applies in addition to general BRSR reporting, though a 2025 SEBI circular allows a choice between reasonable assurance and a third-party Industry-Standards-Forum-benchmarked assessment as the specific compliance route.
