How to compute debt mutual fund tax (post Finance Act 2023)
The Finance Act 2023 revolutionised debt mutual fund taxation by inserting Section 50AA. From 1 April 2023, all gains on debt MF acquired thereafter are taxed at the investor’s slab rate, regardless of holding period. No LTCG benefit, no indexation. Pre-1-April-2023 acquisitions retain old rules.

Step-by-step procedure
See the procedure infobox above.
Pre vs post FA 2023 framework
| Acquisition date | Treatment |
|---|---|
| Up to 31 March 2023 | Old rules: LTCG with indexation if held >36 months; STCG at slab if <36 months |
| 1 April 2023 onwards | Section 50AA: all gains at slab rate |
What Section 50AA covers
Section 50AA defines “specified mutual fund” - any MF investing not more than 35% in equity. This catches:
- Debt MFs (Liquid, Money Market, Short Duration, etc.).
- International FoFs (post-FA 2023 redefinition).
- Multi-asset FoFs (if equity < 35%).
- Gold ETFs (debt-mode).
- Pure debt-based ETFs.
Equity hybrid (> 65% equity) and equity MFs are NOT covered; they retain equity LTCG / STCG framework.
Worked example
Pre-2023 holding:
- Bought 1 March 2022: Rs 1,00,000.
- Sold 1 March 2025 (3 years 0 days = LTCG-eligible).
- Sale: Rs 1,30,000.
- LTCG: Rs 30,000 with indexation.
- Indexation: CII 2022-23 = 331; CII 2024-25 = 363.
- Indexed cost: 1,00,000 × 363/331 = Rs 1,09,667.
- Adjusted LTCG: Rs 30,000 - (1,09,667 - 1,00,000) = Rs 20,333.
- Tax at 20%: Rs 4,067.
Post-2023 holding:
- Bought 1 May 2023: Rs 1,00,000.
- Sold 1 May 2025 (2 years).
- Sale: Rs 1,15,000.
- Gain: Rs 15,000.
- Tax at 30% slab: Rs 4,500.
(Note: tax cost can be similar but mechanism differs.)
Mixed-portfolio FIFO
If your folio has units from before and after 1 April 2023:
- FIFO: oldest units redeemed first.
- Pre-2023 units: old rules apply (LTCG indexation possible).
- Post-2023 units: Section 50AA slab rate.
AMC’s capital gains statement separates these.
International FoF re-classification
Pre-2023: International FoFs treated as non-equity; LTCG 20% with indexation if held > 3 years. Post-2023: Section 50AA - all gains at slab rate.
Many investors held international FoFs with the expectation of LTCG 20% benefit. FA 2023 eliminated this.
Equity hybrid escape
Equity hybrid (> 65% equity) is NOT under Section 50AA. Maintains equity LTCG benefit (12.5% above Rs 1.25 lakh per Section 112A).
For tax-efficient debt-equity allocation post-FA 2023:
- Use equity hybrid / balanced advantage for moderation (equity LTCG benefit).
- Use liquid fund only for short-term parking (slab rate, but minor amount).
- Direct debt allocation: smaller portion or via FD (no tax-efficiency difference now).
