📌 Chapter 13.8 — Taxation in case of Segregated Portfolios of Mutual Funds

Imagine you are an investment advisor reviewing a client’s portfolio after a debt default triggers a segregation event in their mutual fund holding. Your client is confused why their statement now shows two distinct line items, and they are concerned about the tax impact of a potential future sale. As an analyst, you must explain that the segregation is not a new investment, but a partitioning of an existing one.

To determine the tax liability, you cannot simply look at the purchase price of the original fund; you must mathematically apportion the cost basis to reflect the split between the ‘main’ portfolio and the ‘segregated’ portfolio.

This cost allocation process ensures that the total tax base remains consistent with the original cash outlay. The law dictates that the cost of acquisition of the segregated units is derived from the proportion of the net asset value (NAV) of the segregated assets to the total NAV of the scheme just before the credit event. If the segregated asset represented 10% of the fund’s total value, exactly 10% of the investor’s original cost is reallocated to these new units.

Consequently, the cost basis of the original portfolio must be written down by this exact same amount to prevent any duplication of tax benefits or double taxation.

Consider an investor who purchased units in a debt fund for ₹1,00,000. Following a default by a corporate issuer, the fund creates a segregated portfolio, and the fund house communicates that the segregated asset accounts for 5% of the total NAV. You must record the cost of the segregated units as ₹5,000, while the cost basis of the main portfolio units is adjusted to ₹95,000.

When the investor eventually redeems these units, their capital gain will be calculated against these specific, adjusted cost bases rather than the original lump-sum purchase price. Proper documentation of the NAVs provided by the fund house at the time of segregation is essential for this accounting.

This precision is critical for your advisory workflow because inaccurate basis reporting can lead to inflated tax payments or regulatory scrutiny during audits. By maintaining a transparent schedule of the adjusted cost basis, you protect the client from overpaying on capital gains. Furthermore, providing this level of clarity in your client reporting reinforces your professional reliability when navigating the complexities of credit events in debt mutual funds. Clear record-keeping ensures that the integrity of the original investment is maintained throughout the life of the segregated assets.

Nuance

⚠️ Nuance
A common pitfall is the assumption that the cost of segregated units is zero because they are ‘carved out’ or because the underlying asset is in default. Candidates often mistakenly believe that the entire gain upon eventual recovery or sale is taxable without any cost base deduction. In reality, the fiscal framework mandates a proportional allocation of the original cost, which reduces the potential capital gains tax liability compared to a scenario where no cost basis was assigned. Always look for the NAV ratio provided by the fund house at the time of the split to perform the allocation correctly.

Check Your Understanding

Practice Question 1

An investor holds units in a debt fund with a total cost of ₹5,00,000. Due to a credit event, the fund segregates an asset that accounts for 8% of the scheme’s NAV. What is the correct cost of acquisition for the new segregated units?

Practice Question 2

Following a segregation event, how must the original cost basis of the main portfolio units be treated for tax purposes?
