Mutual Fund Taxation Guide: How 12.5% LTCG & 20% STCG Impact Your SIP Returns
Statutory reforms under the Income-tax Act, 2025 and Finance (No. 2) Act, 2024 established Long-Term Capital Gains tax on equity funds at 12.5%, the annual exemption at ₹1.25 Lakhs, and STCG at 20%. Here is how these statutory rules affect your systematic investment plan.
Key Takeaways for Investors
- Equity mutual fund LTCG (holding period > 12 months) is taxed at 12.5% on annual gains exceeding the revised ₹1.25 Lakh threshold.
- Equity mutual fund STCG (holding period ≤ 12 months) has increased to a flat 20% plus applicable cess.
- In an SIP, First-In-First-Out (FIFO) accounting applies: each monthly installment has its own unique 12-month clock.
- Debt mutual fund capital gains continue to be taxed at individual slab rates without indexation benefits.

Capital Gains Tax Framework (Income-tax Act, 2025)
Under the capital gains tax framework codified in the Income-tax Act, 2025 and Finance (No. 2) Act, 2024, equity mutual fund capital gains are governed by Sections 111A and 112A.
Prior to these statutory revisions, equity mutual fund investors had a 10% LTCG rate with an annual exemption limit of ₹1 Lakh, while STCG was taxed at 15%.
Under current law, Long-Term Capital Gains (LTCG) on equity-oriented funds held for more than 12 months are taxed at 12.5%. The annual tax-free capital gains exemption is ₹1,25,000 per financial year.
Short-Term Capital Gains (STCG) on equity funds redeemed within 12 months or less are taxed at 20%.
The FIFO Rule: Why Every SIP Installment Has Its Own Tax Clock
A crucial misconception among retail investors is that an SIP started 5 years ago is completely long-term. Under Indian tax law, this is incorrect.
Under Section 45(2A) and circulars issued by the Central Board of Direct Taxes (CBDT), mutual fund units are redeemed on a First-In-First-Out (FIFO) basis.
This means that when you redeem your units, the earliest purchased units are sold first. If you have been investing ₹10,000 monthly for 5 years (60 installments) and redeem the entire corpus today, the units bought in the last 12 months (installments 49 to 60) are classified as Short-Term Capital Gains (taxed at 20%), while units from months 1 to 48 are classified as Long-Term Capital Gains (taxed at 12.5% above ₹1.25 Lakhs).
Tax Harvesting Strategy: Utilizing the ₹1.25 Lakh Annual Exemption
Because the ₹1.25 Lakh exemption is an annual benefit that resets every April 1st, disciplined investors can practice legal tax harvesting.
By systematically redeeming long-term units with up to ₹1.25 Lakhs in capital gains before March 31st each year and immediately reinvesting the proceeds, you reset your cost basis without paying any capital gains tax.
Over a 15-year SIP horizon, annual tax harvesting can save a disciplined investor between ₹1.5 Lakhs and ₹3 Lakhs in eventual tax liability.
