Flexi cap vs multi cap mutual funds: SEBI 25-25-25 rule, the 2020 carve-out, and tax behaviour

The cap-weighted divide that defines retail equity allocation today began with a single SEBI circular on 11 September 2020. Multi cap funds, until then a marketing label without a structural floor, were ordered to hold at least 25% each in large, mid, and small cap stocks. Eight weeks later, on 06 November 2020, SEBI rolled out the Flexi Cap category as an opt-out. As the cash market opens today, the structural ratio between these two categories continues to route a measurable share of mid and small cap flows. Here is the snapshot that matters before the bell.

Market Snapshot

The cap-tier universe that flexi cap and multi cap funds operate within is defined by AMFI, not by individual fund houses. AMFI publishes a stock list every six months — typically by 15 January and 15 July — covering the previous half-year average full market capitalisation of each NSE and BSE listed company. The classification floor for the current cycle, drawn from this list, is the gating constraint on every cap-mandated scheme.

A multi cap fund must, under SEBI Circular SEBI/HO/IMD/DF3/CIR/P/2020/172 dated 11-Sep-2020, hold a minimum 25% in each of the three buckets, with overall equity at no less than 75%. A flexi cap fund, under the SEBI Circular dated 06-Nov-2020, requires only a 65% equity minimum with full discretion across caps. Both qualify as equity-oriented schemes for taxation since both clear the 65% equity threshold prescribed under Section 112A and Section 111A of the Income Tax Act, 1961.

For SIP investors mapping rupee allocation against cap-tier exposure, the SIP calculator and Step-up SIP calculator translate monthly contributions into a projected corpus across multi-year horizons, helping size the cap-mandated exposure against retirement and goal horizons. The cap-tier identity of the underlying scheme decides how that corpus is distributed across the AMFI universe at any given net asset value cut-off.

What Moved Yesterday

The pre-open framing for any equity mutual fund category centres on whether yesterday's session reinforced or stressed the cap-tier split. Industry pushback against the September 2020 multi cap rule remains instructive: most then-existing multi cap funds, faced with a forced 25% small cap allocation in a thin-liquidity universe, opted to reclassify as flexi cap when SEBI introduced the new category on 06-Nov-2020. That migration permanently changed how cap-weighted flows route through the system, and the asymmetry continues to be the dominant structural feature of the equity mutual fund book today.

Structural drivers worth noting for the flexi vs multi cap debate going into this session:

• AMFI's half-yearly list cycle continues to be the gating event for cap-mandated rebalancing — funds re-test compliance within the calendar month following each list update on 15 January and 15 July.
• The mandatory 25% small cap floor for multi cap funds means any meaningful drawdown in the small cap universe forces incremental buying from this category to maintain the floor — a structural support absent in flexi cap, where the manager can reduce small cap exposure to zero if the discretion is exercised that way.
• The SEBI T+0 settlement expansion to the top 500 stocks, which we covered in our recent settlement analysis, affects large and mid cap liquidity profiles directly but does not yet extend to the deeper small cap universe that multi cap funds must hold under the 11-Sep-2020 mandate.
• AMCs treat the small cap floor as a sticky allocation rather than a tactical lever, which means re-rating cycles in that segment compound flow effects from this category specifically.

What to Watch Today

For the pre-open desk, today's watchlist around the flexi-multi cap split breaks into three tracks.

Cap classification refresh window. AMFI's stock cap classification list is updated half-yearly, and any reclassification of a portfolio holding from mid to small (or vice versa) can trigger compliance-driven rebalancing in multi cap funds. The window matters because the rebalancing is mandatory rather than discretionary — multi cap funds cannot let cap-tier exposure drift below 25% without breaching the 11-Sep-2020 circular. Flexi cap funds, by contrast, can absorb the same reclassification without any portfolio action.

Tax-cycle behaviour. With STCG on equity mutual funds at 20% under Section 111A and LTCG at 12.5% above the Rs 1.25 lakh annual exemption under Section 112A following Finance Act 2024 (effective 23-Jul-2024), redemption math has shifted. Investors comparing flexi and multi cap exits should run the lumpsum calculator to size the corpus against tax exposure across the one-year holding threshold that separates STCG from LTCG. The category of the underlying scheme does not change the tax rate because both clear the 65% equity threshold, but the volatility profile around the one-year mark differs because of the small cap floor.

Subsequent SIP timing. The 65% equity floor for flexi cap means manager discretion can swing toward cash or arbitrage positions during stress windows, which the rigid 25-25-25 multi cap floor cannot. For SIP investors using step-up SIPs, the volatility profile across cap tiers feeds directly into how the annual step-up applies — multi cap step-ups land into a portfolio that cannot defer small cap exposure, while flexi cap step-ups land into a portfolio that can.

Cap-tier mandate comparison

Tax behaviour after Finance Act 2024

Both categories qualify as equity-oriented schemes under Section 112A of the Income Tax Act because both hold 65% or more in domestic equity. Tax behaviour is therefore identical between the two:

• Short-term capital gains (held one year or less): 20% under Section 111A from gains arising on or after 23-Jul-2024.
• Long-term capital gains (held more than one year): 12.5% under Section 112A above the Rs 1.25 lakh annual exemption.
• Securities Transaction Tax paid at purchase and sale, which is the gateway for the lower equity rates.

The relevant comparison for investors is therefore not on tax — both behave identically — but on portfolio drift, manager freedom, and small cap exposure consistency. The 11-Sep-2020 circular ensures that a multi cap investor cannot quietly become a closet large cap investor; the 06-Nov-2020 circular ensures that a flexi cap investor accepts manager discretion as part of the contract.

How the 2020 carve-out reshaped flows

The September 2020 multi cap mandate was a binding constraint on funds that historically ran heavily large cap portfolios under the multi cap label. Faced with the prospect of mandatory rebalancing into small caps within a constrained window, AMCs lobbied SEBI for an alternative. The November 2020 flexi cap circular allowed conversion without a category exit, and the bulk of legacy multi cap funds re-badged within months. The multi cap category that remains today is structurally smaller and structurally more small-cap exposed than the pre-2020 multi cap universe — a distinction often missed in fund selection.

FAQ

What is the difference between flexi cap and multi cap mutual funds?

Multi cap funds must hold at least 25% each in large, mid, and small cap stocks with overall equity at minimum 75%, per SEBI Circular dated 11-Sep-2020. Flexi cap funds must hold at least 65% in equity but the manager can allocate freely across cap tiers, per SEBI Circular dated 06-Nov-2020. Multi cap forces small cap exposure; flexi cap leaves it to manager discretion.

Why did SEBI introduce the flexi cap category in November 2020?

Industry pushback against the 25-25-25 multi cap rule, particularly the mandatory 25% small cap floor in a thin-liquidity universe, led SEBI to create the flexi cap category on 06-Nov-2020 as an alternative. Most legacy multi cap funds reclassified themselves as flexi cap, leaving a smaller and more small-cap-exposed multi cap residue in its place.

Are flexi cap and multi cap funds taxed differently?

No. Both qualify as equity-oriented schemes under the Income Tax Act because both clear the 65% domestic equity threshold. Following Finance Act 2024, both attract STCG of 20% under Section 111A and LTCG of 12.5% under Section 112A above the Rs 1.25 lakh annual exemption.

Who defines large, mid, and small cap stocks?

AMFI publishes a half-yearly list — typically by 15 January and 15 July — classifying NSE and BSE listed stocks based on the previous half-year's average full market capitalisation. Top 100 are large cap, 101 to 250 are mid cap, and 251 onwards are small cap. The list is mandatory across all fund houses.

Which category is better for SIP investors?

Neither is universally better. Investors who want forced small cap exposure for diversification and are comfortable with the higher volatility of a constrained 25% small cap floor may prefer multi cap. Investors who prefer manager discretion to scale exposure up or down based on valuation cycles may prefer flexi cap. The SIP calculator helps project corpus outcomes against contribution and time horizon assumptions.

How often must multi cap funds rebalance?

Multi cap funds must maintain the 25-25-25 floor on an ongoing basis. Following any AMFI half-yearly list update, funds typically rebalance within one month to comply with the revised classification of constituent stocks. Persistent drift below any 25% floor is a breach of the 11-Sep-2020 circular and invites SEBI enforcement.

Can a flexi cap fund hold zero small cap stocks?

Yes. A flexi cap fund has no cap-tier floor beyond the aggregate 65% equity minimum prescribed under the 06-Nov-2020 circular. The manager can hold zero small cap exposure if the discretion is exercised that way, though this is unusual in practice given the search for alpha within the small cap universe over multi-year holding periods.
