Indexation removal for debt MFs (Finance Act 2023)
Indexation removal for debt mutual funds refers to the legislative change effected by the Finance Act 2023 that eliminated the benefit of indexation – the inflation-adjustment of the cost of acquisition using the Cost Inflation Index (CII) – for units of “specified mutual funds” acquired on or after 1 April 2023. Simultaneously, the Finance Act 2023 abolished the concept of long-term capital assets for such funds, treating all gains (irrespective of holding period) as short-term capital gains taxed at the investor’s slab rate. The change fundamentally altered the competitive tax advantage that long-term debt mutual fund investment had over bank fixed deposits for investors in the higher income-tax brackets.

What indexation was and why it mattered
Indexation, under the second proviso to Section 48 of the Income Tax Act 1961, allowed the cost of acquisition of a capital asset to be inflated by the ratio of the Cost Inflation Index (CII) for the year of sale to the CII for the year of purchase. The CBDT notifies the CII annually under Section 48(iiib).
Example of pre-2023 benefit:
An investor purchased Rs 10,00,000 of a debt mutual fund in FY 2016-17 (CII = 264) and redeemed for Rs 14,00,000 in FY 2023-24 (CII = 348).
- Indexed cost: Rs 10,00,000 x (348/264) = Rs 13,18,182.
- Taxable LTCG: Rs 14,00,000 – Rs 13,18,182 = Rs 81,818.
- Tax at 20%: Rs 16,364.
Without indexation, the taxable gain would be Rs 4,00,000 and the old 20% LTCG tax would be Rs 80,000 – nearly five times higher. For investors in the 30% slab, the comparison was even starker.
The Finance Act 2023 amendment
The Finance Act 2023 inserted provisions that specify:
- Units of a “specified mutual fund” (one investing not more than 35% of total proceeds in domestic equity) acquired on or after 1 April 2023 shall be treated as giving rise to short-term capital gains on transfer, regardless of the holding period.
- Such gains shall be included in total income and taxed at the applicable slab rate.
- The indexation benefit under Section 48 is consequently inapplicable (since indexation applies only to long-term capital gains computation, and all gains from such units are now short-term by statute).
The amendment applies based on the acquisition date of the units, not the redemption date. Units acquired before 1 April 2023 retain the old regime.
Definition of “specified mutual fund”
A specified mutual fund is one where not more than 35% of its total proceeds are invested in equity shares of domestic companies. This definition encompasses virtually all debt-oriented fund categories: liquid funds, overnight funds, ultra-short-duration funds, short-duration funds, medium-duration funds, long-duration funds, gilt funds, corporate bond funds, banking and PSU funds, credit risk funds, floater funds, dynamic bond funds, and fixed maturity plans (FMPs).
Conservative hybrid funds (with 10-25% equity) also fall within this definition. Multi-asset funds with equity below 35% are similarly captured. The detailed taxonomy is in debt mutual fund taxation (post-April 2023).
Transitional treatment for pre-April 2023 units
Units acquired before 1 April 2023 retain the pre-amendment tax treatment:
- Holding period below 36 months: STCG, added to total income, slab rate.
- Holding period above 36 months: LTCG at 20% with indexation under Section 112.
The old regime continues to apply until such pre-2023 units are eventually redeemed. An investor who purchased an FMP or long-duration fund in January 2020 and redeems in February 2024 (after more than 36 months) can still claim the 20%-with-indexation benefit. The cut-off is the acquisition date, not the redemption date.
Rationale stated in Finance Bill Memorandum
The Memorandum Explaining the Provisions of Finance Bill 2023 stated the change was intended to:
- Eliminate the tax arbitrage between debt mutual funds and bank fixed deposits.
- Simplify the capital gains tax regime by reducing the number of categories.
- Prevent revenue loss from inflation-adjusted gains escaping tax.
Critics pointed out that this disproportionately affected retail investors who used debt funds for liquidity management, and long-term conservative savers who preferred funds over FDs for their flexibility. Several representations were made to the Ministry of Finance seeking a rollback, but the amendment was enacted without modification.
Contrast with equity mutual funds
| Feature | Debt MF (units acquired after 1 April 2023) | Equity MF |
|---|---|---|
| Long-term holding period | No LTCG category exists | More than 12 months = LTCG |
| LTCG rate | Not applicable (all gains = STCG) | 12.5% under Section 112A |
| Indexation | Not available | Not available (but grandfathering applies) |
| STCG rate | Slab rate | 20% under Section 111A |
| Annual exemption | Not applicable | Rs 1,25,000 for LTCG |
Impact on FMPs
Fixed Maturity Plans (FMPs) were among the most tax-efficient debt instruments before April 2023, precisely because their fixed maturity could be timed to qualify for three-year LTCG with indexation. FMPs launched before 1 April 2023 with maturity dates beyond that date retained the old regime for pre-April 2023 investors. New FMPs launched after 31 March 2023 are subject to the specified-MF slab-rate regime for all investors, eliminating their tax advantage. Fund houses largely stopped launching new FMPs after the amendment.
Cost Inflation Index and continuing relevance
The Cost Inflation Index continues to be notified annually by the CBDT and remains relevant for:
- LTCG on immovable property (under Section 48 with indexation, subject to Finance Act 2024 changes).
- LTCG on unlisted shares (pre-Finance Act 2024 rules).
- Pre-April 2023 debt mutual fund units where the 36-month threshold is met.
For new debt mutual fund purchases after 1 April 2023, the CII is irrelevant.
Interaction with Section 94(7) dividend stripping
Section 94(7) dividend stripping rules continue to apply to debt fund units regardless of the new regime. A loss on debt fund units acquired within three months before the IDCW record date and sold within nine months thereafter is disallowed to the extent of the IDCW received. The disallowance mechanism is unaffected by the specified-MF slab-rate changes.
