The Hidden 30 Basis Points: How SEBI's B30 Rule and Direct Plans Change What You Really Pay in Fund Fees

India's mutual fund industry has swelled to an AUM measured in the tens of trillions of rupees, growing roughly six-fold in a single decade, yet the one lever most investors never pull is the only one they fully control: the fee they pay to hold a fund. Since 1 October 2012, when the Securities and Exchange Board of India's circular CIR/IMD/DF/21/2012 took effect, every scheme has been legally obliged to sell two versions of itself at two different prices for exactly the same portfolio. One is the Direct Plan; the other is the Regular Plan. The difference between them, layered on top of a lesser-known 30 basis point allowance tied to where your money comes from, quietly decides how much of your compounding actually reaches you.

This guide compares the Direct Plan against the Regular Plan for a long-horizon equity investor, unpacks the Total Expense Ratio that sits at the centre of the debate, and explains SEBI's B30 incentive in plain terms. Every rupee of fee you avoid is a rupee that stays invested and keeps compounding, so the stakes are larger than the small percentages suggest.

The Anatomy of a Total Expense Ratio

The Total Expense Ratio, or TER, is the annual charge a mutual fund deducts from your investment expressed as a percentage of daily net assets. It is not billed to you separately; it is netted out of the fund's Net Asset Value every single day, which is precisely why so few investors notice it. The TER bundles fund management fees, registrar and transfer-agent costs, trustee fees, audit charges and, critically for this comparison, distribution and commission expenses paid to the intermediary who sold you the fund.

SEBI caps the TER through slab limits laid out in the SEBI (Mutual Funds) Regulations, 1996 and rationalised by circular SEBI/HO/IMD/DF2/CIR/P/2018/137 dated 22 October 2018. The ceiling falls as a scheme grows larger, on the logic that scale should be passed back to investors. The table below sets out the maximum TER an open-ended equity scheme may charge on its assets under management, measured in basis points where 100 basis points equal one percentage point (see basis points).

For assets between Rs 10,000 crore and Rs 50,000 crore, the 2018 circular requires the TER to fall by 0.05% for every additional Rs 5,000 crore of AUM, or part thereof. These are ceilings, not typical charges, and debt-oriented schemes sit roughly 0.25 percentage points lower at each rung. The number you should hunt for on any scheme's factsheet is the actual TER, not the regulatory maximum.

Side-by-Side Comparison: Direct Plan vs Regular Plan

The Direct Plan and the Regular Plan hold the identical portfolio, are managed by the same fund manager and track the same benchmark. The only structural difference is that the Regular Plan's TER includes the distribution and commission expense paid to a distributor, while the Direct Plan, defined by SEBI as an investment not routed through a distributor, strips that cost out entirely. That single exclusion is the whole story, and it is mandated by the 1 October 2012 circular that required every AMC to offer a separate Direct Plan carrying a lower expense ratio.

Because the commission is a recurring annual charge rather than a one-time load, the gap between the two NAVs widens with every passing year. Consider a simple, clearly illustrative example: assume an equity fund where the Regular Plan charges a TER of 1.75% and the Direct Plan charges 0.75%, a gap of 1.00% or 100 basis points. On a lump sum of Rs 10 lakh, that one percentage point is Rs 10,000 handed over in the very first year alone, before any compounding effect is considered.

Now extend it. Assume a Rs 10,000 monthly SIP invested for 20 years at a gross annualised return of 12% before costs; this is an assumption for illustration, not a guaranteed or historical figure, and you should run your own numbers on the SIP calculator and the lump sum calculator. After deducting the assumed 0.75% Direct Plan TER, the net return works out near 11.25% and the corpus lands around Rs 90.3 lakh. After deducting the assumed 1.75% Regular Plan TER, the net return falls near 10.25% and the corpus lands around Rs 79.1 lakh. The single percentage point of annual fee costs roughly Rs 11.2 lakh over the 20-year horizon in this illustration, all of it drained by commission the portfolio never needed.

The Hidden 30 Basis Points: SEBI's B30 Incentive

Layered on top of the plan-versus-plan gap is a provision most retail investors have never heard of. Under the 2012 circular, an AMC may charge an additional TER of up to 30 basis points on daily net assets to reward inflows from smaller towns. The rule, originally framed around the top 15 cities (B15) and later widened to the top 30 (B30), is designed to push mutual fund penetration beyond India's largest metros, with the list of top cities defined per AMFI data.

The additional 30 basis points is not automatic. It applies only when new inflows from beyond the top cities are at least the higher of two thresholds, as summarised below.

If the qualifying inflows fall short of whichever threshold is higher, the additional expense is charged pro-rata rather than at the full 30 basis points. Crucially, SEBI requires this additional TER to be clawed back if the investor redeems within one year, which stops distributors from churning small-town investors purely to harvest the incentive. Separately, the same regulatory framework obliges every AMC to set apart at least 2 basis points of daily net assets each year towards investor education, a small but permanent line item baked into what you pay.

The practical takeaway is blunt: the B30 mechanism raises the ceiling on what a scheme may charge, and it exists to fund distribution reach. An investor in a Direct Plan sidesteps the commission layer entirely, which is why the Direct route consistently carries the lower TER for the same underlying assets.

Tax Treatment

Fees and taxes are the two frictions that separate a fund's headline return from what you keep, and the tax treatment of the Direct and Regular Plans is identical because they are the same scheme for tax purposes. What matters is the holding period and the asset class, governed by the Income-tax Act as amended by the Union Budget 2024 with effect from 23 July 2024.

For an equity-oriented mutual fund, gains realised within 12 months are short-term and taxed at 20%. Gains on units held for more than 12 months are long-term, taxed at 12.5%, with the first Rs 1.25 lakh of LTCG in a financial year exempt. A surcharge applies at higher income levels, and importantly the surcharge on capital gains is capped at 25% even in the new tax regime rather than the 37% that once applied, plus a health and education cess of 4% on the tax. Note that ELSS funds carry a statutory three-year lock-in, so every ELSS redemption is by construction long-term; you can model the deduction and lock-in on the ELSS calculator.

Because switching from a Regular Plan to a Direct Plan of the same scheme is treated as a redemption followed by a fresh purchase, it can itself trigger a capital gains event and, for equity units held under 12 months, the 20% STCG charge. That timing detail matters: the fee saving from switching is real and permanent, but the switch should be sequenced to avoid an avoidable short-term tax hit. Verify the current rates directly at incometax.gov.in before you act.

Who Should Pick Which

The choice is not about which plan is cheaper, because the Direct Plan is always cheaper by the commission for the same portfolio. The real question is whether the guidance bundled into the Regular Plan's higher TER is worth the recurring cost to you specifically.

The Direct Plan suits the self-directed investor who is comfortable selecting schemes, monitoring the actual TER on the factsheet, rebalancing across large-cap and other categories, and transacting through an AMC website, a registrar and transfer agent, or a stock-exchange platform. Over a 20-year horizon, the compounding of a 1.00% annual saving, worth roughly Rs 11.2 lakh in the illustration above, is a powerful argument for doing the homework yourself.

The Regular Plan can still make sense for an investor who genuinely relies on a distributor or advisor for scheme selection, behavioural discipline during market falls, and paperwork, and who values that hand-holding more than the annual commission it costs. The danger is paying Regular Plan fees for a decade while receiving no advice at all, which is the worst of both worlds. If you are paying the commission, insist on the service it is supposed to buy. For goal-based planning across instruments, compare the Direct route against alternatives such as the PPF calculator at its 7.1% rate for the July-September 2026 quarter and the NPS calculator before committing your long-term corpus.

FAQ

What exactly is the difference between a Direct Plan and a Regular Plan?

They are two versions of the identical mutual fund scheme with the same portfolio and fund manager, mandated by SEBI's 1 October 2012 circular CIR/IMD/DF/21/2012. The Regular Plan's TER includes the distribution and commission expense paid to the intermediary who sold it; the Direct Plan excludes that cost, so it carries a lower expense ratio and a higher NAV over time.

How much can the fee difference cost me over the long term?

It depends on the size of the TER gap and your horizon. In an illustrative example assuming a 1.00% annual gap, a 20-year Rs 10,000 monthly SIP at 12% gross returns produces a corpus near Rs 90.3 lakh on the Direct Plan versus roughly Rs 79.1 lakh on the Regular Plan, a difference of about Rs 11.2 lakh. Run your own figures on the SIP calculator; actual returns are never guaranteed.

What is the B30 30 basis point charge?

Under the 2012 circular, an AMC may add up to 30 basis points to the TER when new inflows come from beyond the top cities, provided those inflows are at least 30% of gross new inflows or 15% of the scheme's year-to-date AUM, whichever is higher. If the threshold is not met, the additional TER is charged pro-rata, and it is clawed back if the investor redeems within one year.

Is the additional B30 expense charged to every investor in the scheme?

The 30 basis point additional TER is a scheme-level charge on daily net assets tied to qualifying B30 inflows, not a fee levied only on B30 investors, though the incentive it funds flows to distributors bringing in small-town money. Choosing a Direct Plan removes the distribution and commission layer that this incentive is designed to support.

How are gains on these plans taxed?

Identically, because both are the same scheme for tax purposes. For an equity-oriented fund, short-term gains on units held 12 months or less are taxed at 20%, and long-term gains on units held longer are taxed at 12.5% above a Rs 1.25 lakh annual exemption, per the Budget 2024 rules effective 23 July 2024, plus a 4% cess.

Will switching from Regular to Direct create a tax bill?

It can. SEBI treats a switch as a redemption of the Regular Plan units and a fresh purchase of Direct Plan units, so if equity units are sold within 12 months the 20% STCG rate applies, and long-term gains above Rs 1.25 lakh attract 12.5%. Sequence any switch to minimise the tax while still capturing the permanent fee saving.

Where can I verify a scheme's actual TER?

Every AMC publishes the current TER of each plan on its website and factsheet, and the figures are consolidated in AMFI's disclosures at amfiindia.com. Always read the actual TER of the specific plan rather than assuming the SEBI regulatory ceiling, because the real charge is often well below the maximum.
