SEBI MF Lite Regulations: Passive-Only AMCs Get Easier Entry Framework From 2025

India's passive investing wave has a new regulatory tailwind. On 16 December 2024, the Securities and Exchange Board of India (SEBI) notified the SEBI (Mutual Funds) Second Amendment Regulations, 2024, creating a lighter-touch framework known as "MF Lite" for asset management companies that intend to launch only passive schemes. The headline relaxation is sharp: a sponsor needs a net worth of just Rs 35 crore to set up a passive-only AMC, against the Rs 100 crore threshold that applies to a full-service AMC running active funds. The framework took effect for new applicants through 2025.

The timing is deliberate. Passive fund assets under management in India crossed Rs 10 lakh crore as the framework was being finalised, and SEBI's stated aim is to lower entry barriers so that more fee-conscious, low-cost products reach retail investors. But MF Lite does not invent a new product. It simply makes it cheaper to launch the two passive vehicles investors already choose between every day: the index fund and the exchange-traded fund (ETF). If 2025 brings a wave of new passive launches, the practical question for an ordinary investor is unchanged and decades old: for a given goal, should you buy an index fund or an ETF?

This pulse breaks down that choice the way a portfolio manager would: structure, cost, tax, and investor fit, using only rates verified against SEBI, the Income Tax Department, and AMFI as of June 2026.

Side-by-Side Comparison

An index fund and an equity ETF can track the exact same benchmark, say the Nifty 50, yet they reach your portfolio through completely different plumbing. An index fund is a conventional mutual fund unit bought and redeemed at one net asset value (NAV) struck once per day after market close. An ETF is a listed security you buy and sell on the NSE or BSE during the 09:15 to 15:30 trading session at a live market price that can drift from its underlying NAV.

That single structural difference cascades into every other distinction that matters.

Both vehicles charge a fraction of what an active fund does, which is the entire point of going passive. SEBI's tiered total expense ratio caps keep passive schemes among the cheapest regulated products on the shelf, and the expense ratio you pay compounds against your returns every single year you stay invested. Over a 20-year horizon, even a difference of 0.30 percentage points in annual cost is the gap between two materially different corpora, which you can model on our SIP calculator or lumpsum calculator.

The cleanest way to see the trade-off: an index fund optimises for automation and simplicity, while an ETF optimises for intraday control and, often, a marginally lower headline expense ratio that can be eroded by trading frictions.

How the MF Lite Framework Reshapes the Shelf

Before MF Lite, every AMC faced the same Rs 100 crore net worth bar regardless of whether it ran 40 active strategies or a single Nifty tracker. SEBI's Second Amendment Regulations, 2024, recognised that a passive-only house carries far less operational and fund-management risk, since it makes no stock-selection calls and simply mirrors a published index. Hence the relaxed Rs 35 crore sponsor net worth and the simplified compliance and disclosure load for MF Lite AMCs notified in December 2024.

The restriction is the safeguard: an MF Lite licence permits only passive schemes that track specified, widely followed indices. A licensed entity cannot quietly pivot to running an active mid-cap fund. For investors, the expected second-order effect through 2025 and 2026 is more competition at the low-cost end, which historically pressures expense ratios downward and widens the menu of index funds and ETFs tracking the same benchmarks. SEBI flagged that passive AUM had already crossed Rs 10 lakh crore as justification for the reform.

This matters because more launches do not automatically mean better outcomes. Two ETFs tracking the identical index can differ in liquidity, assets under management, and price-to-NAV behaviour. A thinly traded ETF with low AUM can show a wide bid-ask spread, meaning the price you transact at sits well away from the fund's true NAV, an invisible cost no expense ratio captures.

Tax Treatment

Tax is where many investors wrongly assume index funds and ETFs differ. For equity-oriented schemes, they are taxed identically. What actually drives your tax bill is the asset class the fund holds and your holding period, not whether the wrapper is an index fund or an ETF. The rates below are the post-Budget 2024 figures, effective for transfers on or after 23 July 2024, as published by the Income Tax Department.

For an equity Nifty 50 index fund or a Nifty 50 ETF, gains booked after holding for more than 12 months qualify as long-term capital gains taxed at 12.5%, with the first Rs 1.25 lakh of such gains in a financial year fully exempt. Gains on units held for 12 months or less are short-term and taxed at a flat 20%. These two rates, 12.5% LTCG and 20% STCG, replaced the earlier 10% and 15% slabs from 23 July 2024.

The non-equity corner is where the wrapper finally bites. A gold ETF or a debt ETF is not equity-oriented, so it follows the non-equity rules: short-term gains are added to income and taxed at your slab, and even long-term gains on debt instruments acquired after 1 April 2023 are taxed at slab with no indexation benefit. The health and education cess of 4% sits on top of the computed tax and surcharge in every case. Surcharge in the new regime is capped at 25%, so the old 37% top rate does not apply to taxpayers under the default regime.

One nuance new ETF investors miss: because an ETF trades intraday, every sale on the exchange is a taxable transfer the moment it executes, just like a direct equity sale. With an index fund, a tax event occurs only on redemption of units. The economic outcome is the same, but ETF trading discipline matters more for keeping the holding period above the 12-month long-term line.

Who Should Pick Which

The MF Lite expansion will flood the shelf with both formats, so the decision rule needs to be principle-based rather than brand-based. Below is the investor-profile mapping a fee-aware adviser would use in 2026.

Choose an index fund if you invest through SIPs. The single strongest argument for index funds is frictionless automation. A monthly systematic investment plan into an index fund runs hands-free at the daily NAV, with no demat account, no broker, and no need to place a manual market order each month. For a salaried investor building a 15-year to 20-year corpus, this discipline outweighs the few basis points an ETF might save. Model the compounding on the SIP calculator.

Choose an ETF if you deploy lump sums and value intraday control. An investor placing a large one-time amount, or one who wants to buy on a sharp market dip at a specific intraday level, gains from the ETF's live pricing. The caveat is liquidity: only pick an ETF with healthy daily volumes and large AUM so the bid-ask spread stays tight. Size a one-time deployment with the lumpsum calculator.

Choose neither for tax-saving; use ELSS instead. Neither a plain index fund nor an equity ETF gives a Section 80C deduction. An investor specifically chasing the Rs 1.5 lakh 80C deduction under the old regime should look at an equity-linked savings scheme, which you can plan on the ELSS calculator. Note that 80C deductions are unavailable in the new tax regime, so the ELSS tax case only stands for old-regime taxpayers.

For first-time investors, the index fund wins on simplicity almost every time. The demat requirement, brokerage, and the discipline of avoiding panic intraday trades make ETFs a poorer first experience. Investors comparing this against retirement-specific routes may also weigh the NPS Tier 2 low-cost equity option, and those eyeing global diversification should note the constraints flagged in our coverage of SEBI's international fund overseas limits.

For most retail investors building wealth steadily, the honest answer is that the wrapper matters less than three habits: keeping costs low, holding past the 12-month line for the 12.5% LTCG rate, and not interrupting the compounding. MF Lite will make the low-cost part easier; the rest is behaviour.

FAQ

Does the SEBI MF Lite framework create a new type of investment product?

No. The MF Lite framework, notified through the SEBI (Mutual Funds) Second Amendment Regulations, 2024 on 16 December 2024, only relaxes the entry rules for AMCs that launch passive schemes. It lowers the sponsor net worth requirement to Rs 35 crore from Rs 100 crore and simplifies compliance. The products themselves, index funds and ETFs, are unchanged; investors should simply expect more of them and potentially lower costs as competition rises.

Are index funds and equity ETFs taxed differently?

No. For equity-oriented schemes the tax treatment is identical. Units held for more than 12 months attract long-term capital gains tax at 12.5%, with the first Rs 1.25 lakh of LTCG in a financial year exempt. Units held for 12 months or less attract short-term capital gains tax at a flat 20%. Both rates are effective from 23 July 2024 per Budget 2024. The difference appears only for non-equity ETFs such as gold or debt ETFs, which are taxed at slab rates.

Do I need a demat account to buy an index fund?

No. An index fund is a conventional mutual fund unit that you can buy directly from the AMC or through a platform without a demat account. An ETF, by contrast, is a listed security and does require a demat account and a stockbroker, because you transact it on the exchange during market hours of 09:15 to 15:30.

What is the price-to-NAV premium or discount on an ETF?

Because an ETF trades at a live market price, that price can sit slightly above (premium) or below (discount) the fund's true net asset value, especially when on-exchange volume is thin. This gap is over and above the expense ratio and tracking error, and it is the main hidden cost of choosing a low-liquidity ETF. Index funds avoid this entirely because they transact strictly at the end-of-day NAV.

Will MF Lite lower the expense ratios I pay?

That is the regulatory intent. By cutting the sponsor net worth bar to Rs 35 crore and easing compliance, SEBI aims to attract new entrants to the passive segment, which crossed Rs 10 lakh crore in AUM around the reform. More competition has historically pressured passive expense ratios downward, but no specific reduction is guaranteed, so always compare the actual TER and tracking error of each scheme before investing.

Can I run a SIP into an ETF?

Only in a limited way. ETF SIPs depend on broker support and are not as seamless as the native, fully automated SIPs available in index funds, which run at the daily NAV with no manual order. For disciplined monthly investing over 10 to 20 years, an index fund SIP is generally the cleaner route; you can project outcomes on Oquilia's SIP calculator.

Is an index fund or an ETF better for a first-time investor?

For most first-time investors, an index fund is the simpler and safer entry point. It needs no demat account, supports automated SIPs, removes the temptation of intraday trading, and transacts at a single transparent NAV. An ETF suits investors who already have a demat account and want intraday pricing control for lump-sum deployment, provided they stick to high-liquidity, large-AUM funds.
