Debt mutual fund indexation removal, Finance Act 2023

The Finance Act 2023 amended the Income Tax Act, 1961, to remove the indexation benefit and the concessional long-term capital gains (LTCG) tax rate of 20 percent that had previously applied to gains from debt mutual fund schemes held for more than 36 months. With effect from 1 April 2023 (for transactions on or after that date), capital gains from specified debt mutual fund schemes are taxed as short-term capital gains at the investor’s applicable income tax slab rate, irrespective of the holding period. This change fundamentally altered the after-tax return profile of debt mutual funds relative to bank fixed deposits and other fixed-income alternatives, and it significantly reduced the attractiveness of debt funds as tax-efficient long-term investment vehicles for investors in the 30 percent income tax bracket.

The pre-2023 tax treatment of debt mutual funds

Prior to the Finance Act 2023 amendment, the taxation of debt mutual fund units under the Income Tax Act, 1961, was as follows:

• Short-term capital gains (holding period less than 36 months): Gains taxed at the investor’s applicable income tax slab rate.
• Long-term capital gains (holding period 36 months or more): Gains taxed at 20 percent with indexation benefit, or 10 percent without indexation (whichever was beneficial to the investor).

The indexation benefit allowed investors to inflate their purchase cost by the Cost Inflation Index (CII) notified annually by the Central Board of Direct Taxes (CBDT), effectively reducing the taxable capital gain by the inflationary component. For an investor in the 30 percent income tax bracket holding a debt fund for three or more years, the effective tax rate on gains after indexation was typically well below 20 percent, often 5–12 percent effectively, depending on the fund’s return and the prevailing inflation rate.

This tax advantage had made debt mutual funds significantly more tax-efficient than bank fixed deposits for investors in higher income tax brackets, for whom FD interest income is fully taxable at slab rates in the year of accrual. A taxpayer in the 30 percent bracket earning 7 percent per annum from an FD would pay approximately 2.1 percent (plus surcharge and cess) per year in tax, while the same investor in a debt fund earning similar pre-tax returns would pay substantially less after indexation and the 20 percent LTCG rate, especially over a 3–5-year holding period.

This differential had materially contributed to the growth of debt mutual fund AUM through the 2010s, particularly among high-net-worth individuals, corporates, and family offices using debt funds as a tax-efficient fixed-income allocation.

The Finance Act 2023 amendment

The Union Budget presented by Finance Minister Nirmala Sitharaman on 1 February 2023 included, in its Finance Bill provisions, an amendment to Section 50AA of the Income Tax Act (a new section inserted by the Finance Bill) that reclassified gains from “specified mutual funds” as short-term capital gains irrespective of holding period. The amendment applied to any mutual fund where not more than 35 percent of the total proceeds are invested in equity shares of domestic companies, effectively capturing all pure debt funds, debt-oriented hybrid funds, gold funds, international funds, and fund of funds as “specified mutual funds”.

The Finance Bill provision passed into law as the Finance Act 2023 and applied to units purchased on or after 1 April 2023. Units purchased before that date retained the indexation benefit for the applicable holding periods under the earlier law, creating a bifurcated tax treatment based on purchase date.

The key changes introduced:

Rationale stated by government

The government’s stated rationale for the change, as articulated in budget documents and post-budget communications, included:

• Horizontal equity: Debt mutual funds and bank fixed deposits are economically similar instruments offering fixed-income returns. The differential tax treatment created an artificial incentive to channel savings into debt mutual funds over FDs, a distortion that the government sought to correct.
• Simplification: Eliminating the three-year holding period distinction simplified the taxation of financial instruments in the debt-equivalent category.
• Revenue: The amendment was expected to increase direct tax revenues as the tax deferral advantage of long-term debt fund holdings was eliminated and gains were taxed at slab rates annually through capital gains at the time of redemption.

Industry bodies including the Association of Mutual Funds in India and the Confederation of Indian Industry objected to the amendment on the grounds that it would discourage long-term savings in debt instruments and would particularly hurt individual investors in the 20–30 percent bracket who had used debt mutual funds as their primary non-equity savings vehicle. AMFI requested a restoration of the LTCG benefit or a reduced transition period for existing investments, but the Finance Ministry maintained the amendment as passed.

Impact on the debt mutual fund industry

The immediate market reaction to the Finance Act 2023 announcement was a sharp surge in debt mutual fund purchases between the budget announcement on 1 February 2023 and 31 March 2023, the last date on which new purchases would qualify for the indexation benefit under the grandfathering provision. Industry data from the Association of Mutual Funds in India showed net inflows of over Rs 50,000 crore into debt schemes in March 2023 alone, as investors rushed to capture the grandfather clause benefit.

From April 2023 onward, net flows into debt schemes moderated, as the tax advantage over FDs was eliminated. The impact was most pronounced for:

• Target maturity funds and long-duration debt funds, which had attracted large AUM specifically for their tax-efficient LTCG treatment.
• Gilt funds, popular among HNIs for their combination of safety and tax-efficient LTCG.
• International fund of funds, which were already subject to debt fund taxation (not equity taxation) and now faced the full slab-rate regime.

Conversely, pure equity mutual funds (where more than 65 percent of assets are in domestic equities) and equity-oriented hybrid funds were unaffected, as their LTCG treatment (10 percent above Rs 1 lakh threshold) remained unchanged.

Subsequent adjustment: Finance Act 2024

The Finance Act 2024 (Union Budget 2024) made a further adjustment: gains from mutual funds (including debt funds) were brought within a revised capital gains framework with STCG at 20 percent and LTCG at 12.5 percent (without indexation) for equity-linked instruments, while debt fund gains remained at slab rate. The 2024 amendments also removed indexation from property and certain other long-term assets, extending the principle of the 2023 debt fund change to a broader set of capital assets.
