How GST on Mutual Fund Distributor Commission Changes Everything (April 1, 2026)

What Actually Changed

On March 12, 2026, the Association of Mutual Funds in India (AMFI) issued circular 123/2025-26, making official what many in the distribution channel already knew: the way asset management companies pay commissions to distributors is about to flip. Starting April 1—with actual payments hitting in May—SEBI's new expense ratio (TER) framework changes everything.

Here's the simple version: Before April 1, when an AMC paid you 1% trail commission, it was already baked in to the fund's expense ratio. That 1% was technically your fee plus the 18% GST your vendor would owe. If you weren't registered for GST, you kept 1%. If you were, you kept ~85 basis points and remitted GST.

After April 1, the structure splits in two. The AMC pays the base commission (85 bps in this example) to everyone—registered and unregistered. Then, separately, they pay 18% GST only to registered distributors who provide a valid tax invoice. Unregistered MFDs? They get 85 bps. Period.

That works out to roughly a 15% reduction in take-home for unregistered distributors. On a ₹100 lakh AUM book earning trail, the gap can add up to ₹12-18 lakh a year.

Breaking Down the Numbers

Let's use actual numbers to see how the before-and-after plays out. Say you earn 1% trail (₹100) from an AMC on a particular fund. That commission sits in the fund's TER limit.

The unregistered distributor loses ₹15.25 on every ₹100 earned. Multiply that across 1,000+ schemes and month after month.

Important correction on composition scheme: Under the new structure, AMCs reimburse the GST component only at 18% against a valid tax invoice. Composition scheme MFDs cannot issue 18% invoices (they issue a "bill of supply" instead). This means the AMC will not pay any GST component to composition scheme distributors. They receive only the base commission of ₹84.75. And they still owe 6% tax on their turnover to the government, paid from their own pocket. That brings their actual net down to approximately ₹79.66 per ₹100 of pre-April commission. That's worse than unregistered MFDs, who at least don't have a tax liability on top.

One detail worth noting: this doesn't affect commission structures for new business or existing business differently. AMFI circular 123/2025-26 explicitly states it applies to both new inflows and existing AUM starting May 2026. No grace period. No phase-in.

Why Unregistered Distributors Are Affected

Technically, unregistered MFDs were never supposed to receive commission on top of GST. The earlier system—where commission payments were inclusive of 18% GST—was more of a structural workaround. It allowed unregistered distributors to function without charging GST to AMCs while keeping the full fee.

The new TER regulations from SEBI close that gap. Commissions are now base + GST. If you're not registered, there's no GST invoice to provide, so you don't get the GST component.

From what I've seen working with MFD firms, many unregistered distributors weren't tracking this regulatory shift closely. A lot of them were earning solid income without the complexity of GST compliance. That changes May 1.

Composition Scheme vs Normal GST: Which Works Better Now?

This is where the change hits hardest, and the math might surprise anyone who's been on composition thinking it's the "simple, low-cost option."

Many small MFDs operate under GST's composition scheme: pay 6% on turnover, skip the input tax credit (ITC) paperwork. Until now, composition was a reasonable default for most. But the new commission structure completely destroys the composition advantage.

Here's why. AMCs will now pay the GST component separately, and only against an 18% tax invoice. Composition scheme MFDs cannot issue an 18% invoice. They're locked into 6% under GST composition rules. So the AMC simply does not reimburse any GST to them. The composition MFD gets the same base commission as an unregistered distributor, but then also owes 6% tax from their own pocket.

Let's walk through it for a distributor earning ₹50 lakh in annual commission (gross, under the old inclusive structure), with ₹2 lakh in claimable ITC on business expenses like office rent, software, and travel.

Before April 1 (commission inclusive of GST):

Composition was better by about ₹2.63 lakh a year. This is why many MFDs stayed on it.

After April 1 (base commission + separate GST component) — CORRECTED:

After the change, normal GST is better by ₹4.54 lakh per year. That's not a small gap. And it's a complete reversal from the pre-April picture where composition was ahead by ₹2.63 lakh. The total swing is over ₹7 lakh annually.

To put it bluntly: if you're on composition and earning ₹50 lakh, you're now taking home ₹39.83 lakh instead of ₹47 lakh. That's a 15.3% drop in net income. Normal GST distributors? Their net doesn't change at all.

The structural advantage of composition doesn't just disappear under the new framework. It reverses into a significant penalty. And with any ITC at all, the gap only widens further in favour of normal registration.

How to Switch from Composition to Normal GST

If you're on the composition scheme and the math above makes you want to switch (it should, for most MFDs earning above ₹20-25 lakh), here's the process:

1. File Form GST CMP-04 on the GST Portal — this is the formal application to withdraw from the composition scheme.

2. The portal will ask for the reason for withdrawal. Select the relevant option (typically "voluntarily opting out").

3. Once CMP-04 is processed, you'll need to file Form GST ITC-01 within 30 days, declaring the stock of inputs and capital goods on which you want to claim ITC going forward.

4. From the effective date of switch, you'll start filing regular GST returns (GSTR-1 and GSTR-3B monthly or quarterly) instead of the simplified composition returns (CMP-08).

5. You can now issue proper 18% tax invoices to AMCs and claim input tax credit on all eligible business expenses.

The switch takes effect from the beginning of the next quarter after filing. So if you file CMP-04 in April 2026, the switch typically applies from July 1, 2026. Plan accordingly. Your accountant can handle the paperwork in a day. The operational shift to monthly/quarterly filing is the real adjustment, but platforms like ClearTax and most CAs handle this routinely.

From what I've seen with MFD firms that moved from composition to normal registration in the past year, most found that once they started tracking ITC properly (office rent, tech tools, even a portion of accountant fees) the gap widened further in favour of normal registration.

The Investor Side of This Change

There's an angle here that hasn't gotten as much attention: the potential benefit for retail investors. A significant share of mutual fund AUM in India sits with non-GST registered distributors—brokers, IFAs, tied agents. Prudent Corporate mentioned on their Q3 FY26 earnings call (January 28, 2026) that over 50% of their AUM flows through non-GST registered channel partners.

Under the old system, when an AMC paid a non-GST distributor ₹100 in commission, that amount sat inside the fund's expense ratio—including the 18% GST that wasn't actually being remitted. It was absorbed as a cost cushion inside the TER.

Under the new framework, that GST buffer comes out. The commission the non-GST distributor receives is smaller, but the fund's expense ratio gets cleaner too. SEBI's January 14, 2026 notification, effective April 1, also reduced other expense items:

• Brokerage caps cut from 12 to 6 basis points in cash markets

• Exit load benefits slashed from 5 bps to zero

• Various other cost reductions across portfolio management and credit rating

The net effect? Average fund expense ratios should come down—perhaps 10-15 bps across most fund categories. A retail investor in a diversified equity fund paying 0.50% expense ratio today might see that drop to 0.38-0.42% by mid-2026.

Over 20 years on a ₹10 lakh investment, even a small reduction in TER compounds into meaningful savings. That's the structural argument for why this change, while difficult for parts of the distribution chain, moves in the direction of lower costs for end investors.

Five Things Every MFD Should Do Before April 1

1. Get GST registered now if you're not already. The ₹20 lakh turnover threshold (₹10 lakh in special category states) applies to services. Most active MFDs hit it. Early registration means cleaner compliance and January 2026 GST filings will reflect the new reality.

2. If you're on composition, file Form GST CMP-04 to switch to normal registration. The composition scheme is no longer viable for most MFDs under the new framework. Run the numbers with your accountant using the tables above. For anyone earning above ₹20-25 lakh, normal GST almost certainly wins now.

3. Check your AUM breakdown by distributor type. Which of your source AMCs have what percentage coming from registered vs. unregistered channels? That tells you which relationships will see commission reductions.

4. Talk to your accountant about ITC tracking. If you move to normal GST, every rupee of eligible business expense (software, office rent, travel) becomes deductible. Start tracking now.

5. Plan communication with clients. Some clients might ask why their advisory fees are staying flat while commission income drops. Be honest. This regulatory change was coming; it's not about performance.
