The Silent Drain: When Smart Cash Management Triggers a Tax Surprise
The treasury team has one simple brief: “Don’t let that cash sit idle.”
So, the company parks surplus liquidity into low-risk corporate cash alternatives — liquid funds, overnight and ultra-short debt funds, short-term debt funds.
Low risk. Decent yield. Smart move.
Until the GST review.
An unexpected line item appears on the reconciliation sheet.
The finance head frowns: “How did managing our own cash turn into a tax adjustment?”
The answer lies in a rarely discussed GST provision that turns an otherwise smart treasury move into a hidden cost.
This week’s Shot uncovers a silent drain on corporate returns — one that hides in plain sight.
Across industries, companies flush with surplus cash turn to debt mutual funds for steady returns. But beneath the surface, a little-known GST provision — the ‘deemed exempt supply’ rule — can quietly eat into those gains.
This rule values mutual fund redemptions at 1% for tax purposes, triggering a proportionate reversal of input tax credit (ITC) on certain expenses.
We break down how it works, why even seasoned CFOs miss it, and how to structure treasury moves without sacrificing valuable credits.
The Case of a Healthcare Company
Recently, a large healthcare manufacturer approached the Authority for Advance Ruling (AAR) with what they thought was a routine question:
We pay GST on services like accounting, legal, and compliance support. Some of these help us with our mutual fund transactions. Can we claim ITC on them?”
The answer from the AAR? No ITC on those inputs for the investment activity, and a proportionate reversal was required for the common input services used across the business.
Why the Law Says No — Without the Legalese
- Business vs Treasury: Your core operations are taxable supplies — ITC applies. Parking surplus in mutual funds is a capital allocation move, not a taxable supply “in furtherance of business.”
- Securities = Exempt: Under GST, mutual fund units are treated as securities, outside the scope of taxable goods/services, and classed as exempt supplies.
- The 1% Rule: GST rules deem 1% of the redemption value as exempt turnover — not 1% of the gain, but 1% of the full sale value.
- Proportionate Reversal: Once exempt supply exists, Rule 42 and Section 17 require proportionate ITC reversal on shared inputs.
How the 1% Deemed Exempt Supply Affects ITC — An Example
ITC Reversal = Value of Exempt Supply/Total Turnover × Total ITC
Say:
- Redemption Value of Mutual Fund Units = ₹15 crore
- Total Turnover of Business = ₹150 crore (including all taxable and exempt sales)
- Total ITC* available = ₹10 lakh
Calculate:
- Value of Exempt Supply = 1% × ₹15 crore = ₹15 lakh
- Ratio = ₹15 lakh / ₹150 crore = 0.01 (or 1%)
- ITC Reversal= 0.01 × ₹10 lakh = ₹10,000
* Under GST, any service costs tied directly to investment activity — such as accounting, advisory, or legal — are ineligible for ITC
Why Corporates Miss This
In practice, treasury teams focus on ROI and liquidity — not the nuances of GST reversals. Tax teams may not be involved in investment choices.
The 1% deemed value rule is buried deep in legislation, and the reversal often appears as a minor reconciliation item, surfacing only during audits.
At a Glance: The Rulebook
Provision | What It Does |
Section 17(2) | No ITC on inputs for exempt supplies |
Section 17(3) | Treats securities as exempt |
Rule 42 | Requires proportional ITC reversal |
Rule 45(2)(b) | Deems 1% of mutual fund value as exempt for ITC purposes |
Treasury Moves to Stay Ahead
- Integrate Tax & Treasury: Loop tax, GST, and compliance teams into treasury policy decisions.
- Track & Accrue: Regularly compute and accrue ITC reversals tied to treasury investments to avoid surprises at period-end.
- Evaluate Net Yield: When choosing between inflows (overnight funds, ultra-short, short-term debt), compare net yield after ITC reversal — not just headline yield.
- Document Usage: Maintain records linking which input services support treasury activity (time sheets, internal memos, invoices).
- Consider Alternatives: If ITC erosion is meaningful, explore cash tools or structures with better GST treatment.
- Periodic Review: Build ITC reversal checks into internal audits and GST compliance reviews.
Idle cash can earn you extra returns.
But if you’re not factoring in GST reversals, your real yield could be lower than you think. In treasury management, the smartest move isn’t just chasing returns — it’s protecting the credits that sustain them.
Because in corporate finance, what you keep matters as much as what you earn. And sometimes, keeping more starts with looking closer at the fine print.
