The SEBI (Alternative Investment Funds) Regulations, 2012 did something the older SEBI (Venture Capital Funds) Regulations, 1996 never attempted: it built a single, coherent taxonomy for the entire universe of privately pooled capital that sits outside mutual funds. At the centre of that scheme lies Regulation 3(4), which sorts every registered AIF into one of three buckets — Category I, Category II and Category III — each carrying its own bargain of regulatory concession and regulatory burden. For the judiciary and CLAT-PG aspirant, mastering this tripartite division is non-negotiable: the category an AIF chooses determines its leverage capacity, its tenure, its concentration limits and, most consequentially, how its income is taxed. This chapter dissects each category against the bare provisions, cross-checked with SEBI's enforcement record.
The gateway: what qualifies as an AIF at all
Before any fund can be classified into a category, it must first satisfy the threshold definition in Regulation 2(1)(b) of the SEBI (Alternative Investment Funds) Regulations, 2012. An AIF is defined as any fund established or incorporated in India in the form of a trust, company, limited liability partnership or body corporate, which is a privately pooled investment vehicle that collects funds from investors — Indian or foreign — for investing in accordance with a defined investment policy for the benefit of those investors.
Two adjectives in that definition do heavy lifting. "Privately pooled" excludes anything raised by public solicitation; an AIF cannot make a public offer of its units. The reference to a "defined investment policy" anchors the entire regulatory architecture, because SEBI polices the fund's conduct against the policy disclosed in its placement memorandum. The definition is also negatively bounded: it expressly excludes mutual funds regulated under the SEBI (Mutual Funds) Regulations, 1996, collective investment schemes, family trusts set up for relatives, ESOP and employee-welfare trusts, holding companies, securitisation trusts and any pool already regulated under another SEBI regulation. Understanding why these are carved out clarifies what the category framework is for — it governs genuinely discretionary, privately raised capital, not retail collective schemes already addressed by the mutual fund and AIF regulatory hub.
Regulation 3(4): the architecture of three categories
Regulation 3(4) is the load-bearing wall of the entire scheme. It directs that an applicant seeking registration shall seek it as one of three categories. The classification is not cosmetic: the category drives the substantive obligations that follow in Chapters III and III-A of the Regulations.
Category I covers AIFs that invest in start-up or early-stage ventures, social ventures, SMEs, infrastructure, or other sectors or areas which the government or regulators consider socially or economically desirable, and includes venture capital funds (including angel funds), SME funds, social venture funds (now "social impact funds") and infrastructure funds. Category II is a residual class — it covers AIFs that do not fall in Category I or III and which do not undertake leverage or borrowing other than to meet day-to-day operational requirements as permitted. Category III covers AIFs that employ diverse or complex trading strategies and may employ leverage, including through investment in listed or unlisted derivatives. The legislative logic is a sliding scale: the more an AIF resembles a publicly desirable, low-risk, long-horizon vehicle, the lighter SEBI's touch; the more it resembles a speculative, leveraged trading vehicle, the heavier the prudential cage.
Category I: the favoured class and its sub-categories
Category I is the regulator's favourite child. Because these funds channel capital into start-ups, SMEs, social ventures and infrastructure — sectors the State wishes to encourage — they are the only AIFs eligible, in principle, for incentives or concessions from the government or other regulators. The definition expressly contemplates that Category I funds "shall include" four named sub-types: venture capital funds, SME funds, social venture (social impact) funds and infrastructure funds.
The crucial sub-category for exam purposes is the angel fund, a species of venture capital fund within Category I governed by the dedicated Chapter III-A. Angel funds historically required a far smaller corpus and accepted contributions from individual angel investors as low as twenty-five lakh rupees over a tranche period, with a cap of forty-nine angel investors per scheme and a lock-in on each investment. The angel-fund regime has been progressively liberalised — SEBI's 2025 framework moved angel funds towards an accredited-investor-only model — but the doctrinal point endures: angel funds sit inside Category I and inherit its leverage prohibition. A candidate should resist the common error of treating angel funds as a fourth category; they are a sub-set of Category I venture capital funds.
The four named sub-categories repay close study because each carries bespoke deployment conditions layered on top of the category-wide rules. A venture capital fund must invest a stipulated proportion of its investable funds in unlisted equity or equity-linked instruments of venture capital undertakings. A social impact fund (formerly social venture fund) must invest predominantly in securities or units of social ventures and may accept grants or muted returns reflecting its philanthropic character. An infrastructure fund must deploy primarily in unlisted securities or units of investee companies engaged in infrastructure. An SME fund must invest predominantly in unlisted or listed-SME-platform securities of small and medium enterprises. The common thread is that Category I status is earned by genuine sectoral commitment, not merely claimed at registration.
Category I: the leverage prohibition
The defining negative feature of Category I is its near-total ban on leverage. Under Regulation 16 (read with the general conditions), a Category I AIF shall not borrow funds directly or indirectly or engage in any leverage except for meeting temporary funding requirements — and even then only for not more than thirty days, on not more than four occasions in a year, and not exceeding ten per cent of its investible funds. This is a tightly fenced operational overdraft, not a leverage facility. The rationale is prudential: funds that enjoy regulatory concessions and channel patient capital into the real economy must not magnify risk through borrowed money.
Category I funds (other than angel funds) are also subject to a concentration limit: they cannot invest more than twenty-five per cent of their investable funds in a single investee company. Each sub-category carries further bespoke conditions — venture capital funds must deploy a stipulated proportion in unlisted equity of venture undertakings; social impact funds must invest predominantly in social ventures; infrastructure funds in infrastructure. These layered obligations mean a Category I fund's investment latitude is the narrowest of the three.
Category II: the residual workhorse
Category II is defined by exclusion: it captures every AIF that is neither Category I nor Category III and that does not undertake leverage or borrowing other than to meet day-to-day operational requirements. In commercial practice this is the largest and most important bucket. It houses the bulk of India's private equity funds, real estate funds, debt funds, distressed-asset funds and most fund-of-funds. Investment data tracked by SEBI has repeatedly shown Category II commitments dwarfing the other two categories combined, reflecting the dominance of private equity and private credit in Indian alternative assets.
Doctrinally, Category II shares Category I's prohibition on leverage — neither may borrow except for operational needs — but Category II enjoys no special government concessions and faces no sectoral straitjacket. A Category II fund may invest across a wide spectrum of listed and unlisted securities, subject to the same twenty-five per cent single-investee concentration ceiling that applies to Category I. It is, in essence, the default home for any privately pooled, unleveraged, long-only investment vehicle that does not fit the socially-desirable mould of Category I.
Category II in the dock: the SREI Multiple Asset order
The supremacy of the placement memorandum — and the consequences of straying from it — were tested in SEBI's adjudication in SREI Multiple Asset Investment Trust (Adjudicating Officer's Order dated 29 November 2017, in respect of SREI Multiple Asset Investment Trust and SREI Alternative Investment Managers Limited). The fund, a Category II AIF, had declared in its private placement memorandum and investment committee minutes that its per-investee corpus deployment would lie in a band of roughly fifty crore to two hundred crore rupees. SEBI found that investments had been made outside this self-declared limit, contrary to the discipline that the manager must conduct the AIF's activities in accordance with the placement memorandum circulated to unit-holders.
The order is doctrinally significant as one of SEBI's earliest substantive engagements with the AIF Regulations, establishing that the placement memorandum is not mere marketing but a binding constraint enforceable by the regulator. The matter was subsequently resolved through a settlement order in 2018. For an aspirant, SREI Multiple Asset illustrates that category classification merely sets the outer frame; within it, the fund is held to its own disclosed investment policy — the obligation that links back to the manager's duties discussed in the fund-management and AMC chapter.
Category III: complex strategies and leverage
Category III is the most permissive on strategy and the most constrained on prudential oversight. It covers AIFs that employ diverse or complex trading strategies and may employ leverage, including through investment in listed or unlisted derivatives. This is the regulatory home of Indian hedge funds and of long-short and arbitrage funds that trade actively in listed securities. The trade-off is sharp: in exchange for permission to leverage and to trade derivatives, Category III funds shoulder heavier reporting, higher manager skin-in-the-game and — critically — a different and generally harsher tax treatment.
Leverage in Category III is permitted but capped. By SEBI circular, the leverage of a Category III AIF, computed on the prescribed basis, shall not exceed two times the net asset value of the fund. A fund that breaches the cap must square off the excess exposure and bring leverage back within the limit by the end of the next working day, without prejudice to SEBI's enforcement powers. This two-times-NAV ceiling is the single most-tested numerical fact about Category III and should be committed to memory alongside the concentration limit.
The breadth of permissible strategy is what distinguishes Category III commercially. A Category III fund may run long-short equity, may take directional and hedged positions in derivatives, may pursue arbitrage between cash and futures markets, and may rebalance its book frequently — activities that would be incompatible with the close-ended, long-horizon design of Categories I and II. This is precisely why Category III alone is permitted to be open-ended: liquid, mark-to-market positions can support periodic subscription and redemption. The price of that freedom is the most intensive disclosure and risk-reporting regime of the three categories, including periodic reporting of leverage to SEBI, because a leveraged trading book poses systemic and investor-protection risks that a patient-capital venture fund does not.
Concentration, corpus and investor conditions across categories
Several general conditions in Regulation 10 apply to all three categories, with two divergences worth memorising. The common floor: every scheme of an AIF must have a minimum corpus of twenty crore rupees (with a reduced floor historically prescribed for angel funds); each investor must commit at least one crore rupees (reduced to twenty-five lakh for angel investors), with a relaxed floor for employees and directors of the AIF or manager; and an AIF scheme shall not have more than one thousand investors (angel-fund schemes being capped far lower).
The continuing-interest requirement is the key divergence and a frequent examination trap. The manager or sponsor must maintain a continuing interest in the AIF as skin in the game. For Category I and Category II, that interest is the lower of two and a half per cent of the corpus or five crore rupees. For Category III, the bar doubles to the lower of five per cent of the corpus or ten crore rupees. The concentration limits also diverge: Category I and II funds may not invest more than twenty-five per cent of investable funds in one investee company, whereas Category III is held to a stricter ten per cent ceiling. The pattern is consistent — Category III, being the riskiest, faces tighter prudential limits even as it enjoys the widest strategic freedom. These conditions connect directly to the role of the sponsor and manager who must fund and police that continuing interest.
Tenure: close-ended versus open-ended
The structural distinction between the categories surfaces sharply in Regulation 13, which governs tenure. Category I and Category II AIFs are required to be close-ended and must carry a minimum tenure of three years. The logic flows from their illiquid, long-horizon investments — venture capital, infrastructure and private equity cannot accommodate daily redemptions, so the fund is locked for a fixed life with extensions permitted only in the prescribed manner with investor consent.
Category III, by contrast, may be either open-ended or close-ended. Because Category III funds typically trade in liquid listed securities and derivatives, an open-ended structure permitting periodic subscription and redemption is workable, while those that choose a close-ended structure must observe the three-year minimum tenure that applies to close-ended schemes. The tenure rule is therefore a clean mnemonic: Categories I and II are always close-ended; Category III alone may breathe in and out as an open-ended fund.
Taxation: the pass-through divide and the 115UB regime
Taxation is where the categories diverge most consequentially, and it is heavily examined. Under Section 115UB of the Income-tax Act, 1961, Category I and Category II AIFs enjoy pass-through status for income other than business income: income earned by the fund (capital gains, interest, dividends) is taxed not at the fund level but directly in the hands of the investors, as if they had made the investment directly. The fund is treated as a conduit. This statutory pass-through is a deliberate policy incentive that aligns with Category I and II's role as channels for patient capital.
Category III AIFs enjoy no statutory pass-through under Section 115UB. Their income is taxed at the fund level — for a fund structured as a trust, potentially at the maximum marginal rate where the trust is treated as indeterminate. This category-driven tax asymmetry is one of the strongest practical reasons a sponsor's choice of category matters far beyond mere labelling, and it is unaffected by the SEBI regulatory framework, which is silent on tax.
Category III taxation litigated: Equity Intelligence AIF Trust
The fund-level taxation of Category III AIFs structured as trusts came before the Delhi High Court in Equity Intelligence AIF Trust v. Central Board of Direct Taxes (judgment dated 29 July 2025). The dispute centred on CBDT Circular No. 13 of 2014, which the Revenue had read as treating a Category III AIF trust as an "indeterminate" trust — and therefore taxable at the maximum marginal rate — wherever the names of the beneficiary-investors were not set out in the trust deed.
The Delhi High Court quashed that reading, holding that the mere non-mention of investor names in the original trust deed does not render a Category III AIF an indeterminate trust. Where the beneficiaries are ascertainable — even if not individually named in the deed — the trust is determinate and may be taxed at normal rates rather than automatically at the maximum marginal rate. While the decision did not confer statutory pass-through on Category III funds (that remains a matter for Section 115UB, which excludes them), it removed a punitive presumption and materially improved their tax position. For the aspirant, Equity Intelligence is the leading recent authority on how the determinate-trust principles of the Income-tax Act interact with the SEBI category framework.
Enforcing the limits: the Indgrowth Capital order
SEBI's willingness to enforce category-specific conditions is illustrated by its adjudication in the matter of Indgrowth Capital Fund-I (Adjudication Order dated June 2022). The proceedings examined the fund's compliance with the conditions attaching to its category and its placement memorandum, reinforcing the principle established in SREI Multiple Asset that an AIF's category classification carries continuing, enforceable obligations — on concentration, on investment policy and on reporting — and that breaches attract monetary penalties under the SEBI Act.
Read together, the SEBI orders make a single doctrinal point that examiners reward: category selection is the beginning, not the end, of compliance. Once an AIF declares itself Category I, II or III, it binds itself to that category's leverage rules, concentration ceilings, continuing-interest threshold and tenure structure, and SEBI will hold it to those terms. The choice is a one-way ratchet that shapes everything from the fund's borrowing capacity to its tax bill.
Comparing the three categories at a glance
The cleanest way to retain the scheme is to array the three categories against five axes. Strategy and assets: Category I funds socially or economically desirable sectors (start-ups, SMEs, social ventures, infrastructure); Category II is the residual long-only bucket (private equity, debt, real estate, fund-of-funds); Category III runs complex and leveraged trading strategies (hedge, long-short, arbitrage). Leverage: prohibited for Categories I and II (operational borrowing only); permitted for Category III up to two times NAV. Concentration: twenty-five per cent single-investee cap for Categories I and II; ten per cent for Category III.
Tenure: Categories I and II must be close-ended with a three-year minimum; Category III may be open or close-ended. Taxation: Categories I and II enjoy Section 115UB pass-through; Category III is taxed at the fund level. Continuing interest: two and a half per cent or five crore for Categories I and II; five per cent or ten crore for Category III. The consistent thread is the inverse relationship between strategic freedom and prudential leniency: Category III buys the right to leverage and trade derivatives at the price of tighter concentration limits, higher manager commitment and harsher tax. These distinctions, layered on the broader fiduciary architecture of trustees and managers covered in the trustee and AMC chapters, complete the picture of how SEBI regulates privately pooled capital.
Frequently asked questions
What is the basic difference between Category I, II and III AIFs under Regulation 3(4)?
Category I invests in socially or economically desirable sectors (venture capital, SME, social venture and infrastructure funds) and may receive government concessions; Category II is the residual class (private equity, debt, fund-of-funds) that takes no leverage beyond operational needs; Category III employs complex or leveraged trading strategies, including derivatives, and houses hedge funds. The categories form a sliding scale of strategic freedom against prudential constraint.
Can a Category I or II AIF borrow or use leverage?
No, not for investment. Category I and II AIFs are prohibited from leverage and may borrow only to meet temporary or day-to-day operational funding needs. For Category I the operational overdraft is tightly fenced — not more than thirty days at a time, on not more than four occasions a year, and not exceeding ten per cent of investible funds. Only Category III may employ genuine investment leverage, capped at two times its net asset value.
How are the three categories of AIF taxed?
Category I and Category II AIFs enjoy pass-through status under Section 115UB of the Income-tax Act, 1961, so income (other than business income) is taxed in the investors' hands and not at the fund level. Category III AIFs have no statutory pass-through and are taxed at the fund level. In Equity Intelligence AIF Trust v. CBDT (Delhi High Court, 29 July 2025), the court held that a Category III AIF trust is not automatically indeterminate merely because investor names are absent from the trust deed.
What are the tenure rules for the different AIF categories?
Under Regulation 13, Category I and Category II AIFs must be close-ended with a minimum tenure of three years, reflecting their illiquid long-horizon investments. Category III AIFs may be either open-ended or close-ended; if close-ended they too observe the three-year minimum. The mnemonic is that Categories I and II are always close-ended while Category III alone may be open-ended.
Why does the SREI Multiple Asset Investment Trust order matter for AIF classification?
In SREI Multiple Asset Investment Trust (SEBI Adjudicating Officer's order dated 29 November 2017, later settled in 2018), SEBI found that a Category II AIF had made investments outside the per-investee limits declared in its own private placement memorandum. The order established that the placement memorandum is a binding, enforceable constraint and that category classification carries continuing obligations — a point reinforced in the Indgrowth Capital Fund-I order of June 2022.
What continuing interest must the manager or sponsor maintain, and does it vary by category?
Yes. Under Regulation 10, for Category I and Category II AIFs the manager or sponsor must hold a continuing interest of the lower of two and a half per cent of the corpus or five crore rupees. For Category III the bar doubles to the lower of five per cent of the corpus or ten crore rupees. This skin-in-the-game requirement is separate from the minimum corpus of twenty crore rupees and the one crore minimum investment per investor.
