- Debt Funds (Purchased ≥ 1 Apr 2023): Entire gain taxed at your income slab rate irrespective of holding period (no indexation / LTCG benefit).
- Legacy Debt Funds (Purchase < 1 Apr 2023): If held ≥ 36 months: LTCG @20% with indexation; otherwise taxed at slab rate.

FAQs – Mutual Fund Capital Gains Tax
Is indexation still available for debt mutual funds?
Only for units purchased before 1 April 2023 and held for ≥ 36 months; new purchases lose indexation and are taxed at slab rates.
How is equity mutual fund LTCG calculated?
Total gain minus the ₹1 lakh annual exemption; remaining taxed at 10% without indexation.
Are ELSS funds taxed differently?
No, ELSS follow equity taxation. The 3‑year lock-in doesn’t change LTCG rules.
Does this include cess & surcharge?
For simplicity the calculator excludes cess/surcharge. Add 4% (or applicable) to approximate total liability.
