SEBI's MF Lite: a lighter rulebook for index funds and ETFs, with net worth cut to Rs 35 crore

On 31 December 2024, the Securities and Exchange Board of India issued circular SEBI/HO/IMD/PoD2/P/CIR/2024/183, creating a separate, lighter rulebook for passively managed schemes called the Mutual Funds Lite, or MF Lite, framework. The headline number is the capital bar: an asset management company set up only to run passive products can now be licensed on a net worth of Rs 35 crore, against the Rs 50 crore minimum that a conventional AMC must hold under the SEBI (Mutual Funds) Regulations, 1996. That Rs 35 crore can fall further to Rs 25 crore once the AMC records five consecutive years of profit.

For an ordinary investor the plumbing behind a fund is invisible, but the consequences are not. A cheaper, faster route to launch index funds and exchange-traded funds should mean more trackers, tighter tracking and, over time, lower costs on the two products that already dominate passive investing in India. The practical question this piece answers is the one search intent keeps circling back to: index funds versus ETFs for a long-term passive portfolio, and which of the two the MF Lite expansion actually serves best.

Both products track the same underlying baskets, and under MF Lite the initial scope is explicitly index funds, ETFs and fund-of-funds tracking domestic equity indices where the collective or underlying assets under management are at least Rs 5,000 crore. So the choice is rarely about what you own. It is about how you buy it, what it costs to hold and how it is taxed. This article works through all three.

What MF Lite Actually Relaxes

The 31 December 2024 circular does not touch how a scheme is run day to day; it lowers the barriers to setting one up. SEBI kept the investor-facing safeguards and stripped back the entry requirements that made a passive-only AMC uneconomic. The relaxations sit in five areas.

The logic SEBI set out in the December 2024 circular is that a fund which simply replicates a published index carries far less discretionary risk than an actively managed scheme, so the compliance and capital load should be proportionate. A passive tracker has no fund manager taking stock-selection calls, no style drift and no research desk to police; its job is to mirror an index within a tight tracking error. Lowering the cost of running that machinery is meant to pull in new sponsors and push down the expense ratio that investors ultimately pay.

This is the third significant passive-and-product reset from the regulator in roughly a year, alongside the Specialized Investment Funds regime with its Rs 10 lakh per-PAN floor and the February 2026 recategorisation that placed a 50% overlap cap on sectoral and thematic funds. Read together, they point the retail investor firmly towards low-cost, rules-based exposure.

Side-by-Side Comparison

An index fund and an ETF tracking the same index own almost identical portfolios. The differences are entirely in the wrapper. An index fund is bought and sold at a single end-of-day net asset value, the NAV, directly from the AMC, and needs no demat account. An ETF is a listed security that trades on the exchange through the session, so its price moves continuously and you need both a demat and a trading account to hold it.

That single structural split, settled since ETFs first listed in India in 2001, drives every practical difference below.

For a disciplined monthly investor, the index fund wins on convenience. A systematic investment plan into an index fund debits a fixed rupee amount and buys fractional units automatically at that day's NAV, with SIPs available from as little as Rs 100 to Rs 500 at many AMCs. Automating the same rupee cost into an ETF is clumsier, because you can only buy whole units at whatever the market throws up on debit day, and the execution depends on your broker.

The ETF wins on transparency of cost and, for larger tickets, on flexibility. Because it trades live, a lump-sum investor deploying a large amount through the lumpsum calculator math can time entry within the session rather than accepting a blind end-of-day NAV. The trade-off is the bid-ask spread and the risk of buying at a premium to NAV when on-screen liquidity is thin, a real cost that does not show up in the expense ratio. SEBI caps the total expense ratio for index funds and ETFs at 1.00% under Regulation 52 of the SEBI (Mutual Funds) Regulations, 1996, and in practice competitive trackers run well inside that ceiling.

The assets under management threshold in MF Lite, Rs 5,000 crore of collective or underlying AUM for an eligible index, is a deliberate quality gate. It confines the lighter regime to broad, deep, well-traded indices where replication is cheap and tracking error is naturally low, which benefits both wrappers but especially ETFs, whose real-world cost depends on the liquidity of the basket they hold.

Tax Treatment

Here the two products are treated identically, because Indian tax law looks through the wrapper to the underlying holding. An index fund or ETF that tracks a domestic equity index holds close to 100% equity, comfortably clearing the 65% equity threshold that defines an equity-oriented scheme, so both are taxed as equity. The rates below follow the capital-gains structure set in Budget 2024, effective for transfers on or after 23 July 2024.

The mechanics are worth stating precisely. Sell an equity index fund or equity ETF within twelve months of buying and any gain is a short-term capital gain taxed at 20% under Section 111A. Hold beyond twelve months and the gain is long-term, taxed at 12.5% under Section 112A, with the first Rs 1,25,000 of aggregate long-term equity gains in a financial year exempt. These rates and the raised Rs 1.25 lakh exemption are the post-Budget 2024 figures published by the Income Tax Department at incometax.gov.in.

Because the tax treatment is the same, tax should not decide the index-fund-versus-ETF question for domestic equity trackers. It becomes decisive only when you compare either against a tax-advantaged wrapper. An ELSS fund, for instance, delivers a Section 80C deduction of up to Rs 1,50,000 in the old regime that a plain index fund or ETF cannot, though it carries a three-year lock-in that a passive tracker does not. That comparison, old regime only, sits outside today's scope but is the natural next branch for a passive investor optimising for tax.

One practical tax edge favours the index fund for a monthly saver. Every ETF purchase is a separate lot with its own acquisition date, so tracking holding periods and computing gains across dozens of small buys is fiddly; a single index fund folio consolidates the same SIP flow into one statement, which the twelve-month LTCG line makes easier to manage at redemption.

Who Should Pick Which

The MF Lite framework is designed to widen the shelf for both products, so the decision comes back to investor behaviour rather than regulation. Three profiles cover most cases.

The systematic, hands-off saver should default to the index fund. If your plan is a fixed monthly amount into a broad-market tracker for a decade or more, the frictionless SIP, the absence of a demat account, the Rs 100 to Rs 500 entry point and the single consolidated statement all favour the open-ended index fund. You give up intraday pricing you were never going to use anyway. The 12.5% LTCG rate beyond twelve months rewards exactly this buy-and-hold pattern.

The cost-sensitive, market-aware investor with a demat account should lean ETF, provided they can trade with discipline. If you deploy larger, lumpier amounts, already hold a demat account and will check the on-screen premium or discount to NAV before hitting buy, the ETF's live pricing and often keener expense ratio inside the 1.00% cap can shave holding costs. The risk you must own is the spread and the temptation to trade a long-term holding intraday.

The first-time or small-ticket investor should almost always start with the index fund. Without a demat account, and with amounts too small to absorb ETF spreads efficiently, the index fund is the cleaner entry into passive investing. As MF Lite pulls in new AMCs from 2025 onward and the passive shelf deepens, this cohort gains the most from cheaper, simpler trackers, because they were the segment conventional economics served worst.

Whichever wrapper you choose, the MF Lite reform does not change what you own; it changes how many low-cost ways there will be to own it. The Rs 35 crore net worth floor, down from Rs 50 crore, is a supply-side reform whose payoff reaches investors as more choice and, over time, lower expense ratios on index funds and ETFs alike.

FAQ

What is SEBI's MF Lite framework in one line?

It is a lighter regulatory rulebook, introduced by SEBI circular dated 31 December 2024, for AMCs that run only passive schemes such as index funds and ETFs, cutting the minimum net worth to Rs 35 crore from the Rs 50 crore a conventional AMC needs.

Does MF Lite change how my existing index fund or ETF is taxed?

No. MF Lite is a licensing and disclosure reform for fund houses; it does not alter tax law. Equity index funds and equity ETFs are still taxed at 20% STCG within twelve months and 12.5% LTCG beyond, with the first Rs 1,25,000 of long-term equity gains exempt each year, per the Budget 2024 rules effective 23 July 2024.

Can any fund house use the MF Lite route?

Only for eligible passive products. The 31 December 2024 circular initially limits MF Lite to index funds, ETFs and fund-of-funds tracking domestic equity indices with at least Rs 5,000 crore of collective or underlying AUM, and the AMC must meet the Rs 35 crore net worth bar.

Is an index fund or an ETF cheaper to hold?

Both sit under SEBI's 1.00% total expense ratio cap for passive schemes under Regulation 52. ETFs often quote a lower headline expense ratio, but an ETF also carries a bid-ask spread and possible premium or discount to NAV that an index fund, transacting at a single daily NAV, avoids. Net cost depends on how you trade.

Do I need a demat account for both?

No. An ETF is a listed security and needs a demat plus trading account. An index fund is bought directly from the AMC into a folio and needs no demat account, which is why first-time and SIP investors usually prefer it.

Will MF Lite reduce expense ratios I pay?

Not immediately and not by regulation. By lowering the Rs 35 crore capital bar and easing sponsor and trustee requirements, the December 2024 framework is meant to attract more passive-only AMCs, and greater competition on broad-index trackers is the mechanism through which expense ratios could fall over time.

How does this connect to SEBI's other 2024-26 reforms?

MF Lite is one of three linked moves: the Specialized Investment Funds regime with its Rs 10 lakh per-PAN minimum, the February 2026 recategorisation that capped sectoral and thematic overlap at 50%, and MF Lite itself. Together they steer retail money towards transparent, low-cost, rules-based exposure.
