Capital Gains Tax – Debt Funds
Calculate tax on debt mutual fund redemptions. Post-April 2023 amendment: all gains taxed at your income slab rate (no indexation). Includes pre-April 2023 LTCG with indexation for old investments.
Capital Gains Tax — Debt Funds
Post-April 2023: slab rate · Pre-April 2023: 20% with indexation
Post April 2023 purchases: gains taxed at slab. Pre-April 2023: LTCG 20% + indexation if held 3+ years.
The Finance Act 2023 removed the LTCG benefit (20% with indexation) for debt mutual funds bought after 1 April 2023. Now all gains are added to income and taxed at your slab rate. For investors in the 30% bracket, this makes debt mutual funds less attractive than FDs for short-to-medium horizons. Target Maturity Funds and FMPs hold some advantage at longer durations.
Tax on Debt Mutual Funds — Post April 2023 Rules
The Finance Act 2023 fundamentally changed how debt mutual funds are taxed. For units purchased after 1 April 2023, all capital gains are now added to your income and taxed at your applicable slab rate — the same as a bank FD. The earlier benefit of 20% tax with indexation for holdings over 3 years has been removed for new investments.
Pre-April 2023 investments retain the old treatment
Debt mutual fund units purchased before 1 April 2023 still enjoy the old rules: gains held for more than 36 months qualify as Long-Term Capital Gains and are taxed at 20% with CII-based indexation. This significantly reduces the effective tax, especially for investments held 5–10 years as inflation-adjusted cost erodes the taxable gain.
Debt funds vs FD — which is better now?
Post-2023, both FD interest and debt fund gains are taxed at slab rate. The key remaining advantage of debt funds: FD interest accrues and is taxable every year even without withdrawal, while debt fund gains are taxed only on redemption. This deferred taxation provides a compounding advantage over long holding periods, especially for investors who don't need annual income.
What is the Cost Inflation Index (CII)?
CII is a government-published index used to adjust purchase cost for inflation when computing LTCG with indexation. The indexed cost = Purchase price × (CII of sale year ÷ CII of purchase year). For a debt fund bought in FY 2015-16 (CII 254) and sold in FY 2025-26 (CII ~389), the indexed cost increases by 53% — dramatically reducing taxable gain for old investments.
