How Your SIP Mutual Fund Returns Get Taxed (It's Not Simple)

The Part Nobody Explains

You start a SIP, it grows over years, you redeem it — and then your CA sends you a tax computation that looks nothing like what you expected. That's because SIP taxation has three moving parts: holding period, gain type, and FIFO ordering.

This guide decodes all three.

Short-Term vs Long-Term Capital Gains

For Equity Mutual Funds (and Equity ETFs)

The ₹1.25L LTCG exemption is per financial year, across all equity gains combined.

For Debt Mutual Funds (post April 2023)

All gains are taxed at your income tax slab rate regardless of holding period. The 3-year LTCG benefit for debt funds was removed by Finance Act 2023.

For Hybrid / Balanced Funds

Depends on the fund's equity allocation:

• Equity-oriented (>65% equity) → Same rules as equity mutual funds
• Debt-oriented (<65% equity) → Same rules as debt funds (slab rate)

The FIFO Problem

This is the one that trips people up the most.

FIFO = First In, First Out. When you redeem from a SIP, the oldest units are treated as sold first.

Example: You've been doing ₹5,000/month SIP for 24 months (24 installments). You redeem ₹30,000 today.

The ₹30,000 redemption will be matched to the first few months of your SIP — your oldest units. Those earliest units have been held the longest, so they likely qualify as long-term. But units from your recent installments? Still short-term.

This matters because: Even a partial redemption might trigger both STCG and LTCG depending on which units are sold.

Real Example with Numbers

Monthly SIP: ₹10,000 in a large cap fund

Started: July 2023

Partial redemption: ₹50,000 in August 2025

FIFO means units from July 2023 → June 2024 installments are sold first (13 months of ₹10,000 = ~₹1.3L invested).

• July 2023 to July 2024 installments: held 12+ months → LTCG at 12.5%
• August 2024 onwards: held under 12 months → STCG at 20%

Most platforms (Zerodha, Groww, Kuvera) will show you this breakdown in their Capital Gains Statement — download this before filing your ITR.

LTCG Exemption: The ₹1.25L Rule

You don't pay LTCG on equity funds until your total long-term capital gains across all equity investments (funds + stocks) cross ₹1.25 lakh in a financial year.

Smart move: If your LTCG is just above ₹1.25L, consider whether partial redemption timing (before March 31 vs after April 1) changes which financial year the gains fall in.

The Dividend vs Growth Question

• Growth option: Tax is only triggered when you redeem. You control the timing.
• Dividend option: Every dividend distribution is added to your income and taxed at your slab rate (TDS at 10% deducted by the fund house above ₹5,000/year).

For most people in the 30% bracket, growth option is significantly better than dividend.

Indexation — Is It Gone?

For equity funds: never had it. Indexation (adjusting the purchase price for inflation) only ever applied to debt and gold funds.

For debt funds: The indexation benefit was removed from April 2023 for funds with under 35% equity allocation. All gains now taxed at slab rate.

What to Download Before Filing

Every mutual fund platform provides a Capital Gains Statement for the financial year. Download yours from:

1. Your fund's registrar (CAMS or KFintech) → consolidated statement for all funds
2. Directly from Zerodha Console, Groww, Kuvera, or your broker

This statement shows:

• Each redemption
• Purchase date of units sold (FIFO)
• Short-term vs long-term classification
• Gain/loss amount

Hand this to your CA or use it to fill Schedule CG in your ITR-2 or ITR-3.

TL;DR

• Equity SIP gains held 12+ months → LTCG at 12.5%, first ₹1.25L/year exempt
• Equity SIP gains held under 12 months → STCG at 20%
• Debt fund gains (post Apr 2023) → slab rate, no exemption
• Redemptions follow FIFO — your oldest SIP units exit first
• Download Capital Gains Statement before filing your ITR
• Growth option is almost always better than dividend for taxpayers above 20% slab
