Capital Gains on Mutual Funds explained

A capital gain is the profit you make when you redeem mutual fund units for more than you paid for them. Buy at a NAV of ₹100, redeem at ₹140, and ₹40 per unit is your capital gain. Whether the taxman calls that gain "short-term" or "long-term" — and how much tax you pay — depends on the type of fund and how long you held the units.

The two clocks: equity and debt

For equity funds (65%+ in Indian shares), units held for more than 12 months produce long-term capital gains (LTCG), taxed at 12.5% — and the first ₹1.25 lakh of LTCG each financial year is exempt. Sell within 12 months and the gain is short-term (STCG), taxed at 20%. For debt funds bought after 1 April 2023, there is no long-term rate at all: gains are added to your income and taxed at your slab rate, however long you hold.

A worked example

Say you invested ₹3,00,000 in a flexi-cap fund and redeem it two years later for ₹4,50,000. The ₹1,50,000 gain is long-term. Knock off the ₹1,25,000 exemption (assuming you used none of it elsewhere that year) and only ₹25,000 is taxable — at 12.5%, that is a tax bill of about ₹3,125 on a ₹1.5 lakh profit. Had you redeemed at 11 months instead, the whole ₹1,50,000 would be short-term and taxed at 20% — ₹30,000. The one-month difference costs nearly ten times the tax.

SIPs: every instalment has its own birthday

Redemptions follow FIFO (first in, first out) — the oldest units leave first — and each SIP instalment's holding period is counted separately. If you have run a monthly SIP for 14 months and redeem everything today, only the first two instalments are long-term; the other twelve are short-term. Investors are often surprised by an STCG entry on what felt like a "long-term" SIP.

Common mistakes to avoid

• Forgetting gains are realised only on redemption. Your NAV rising costs you nothing in tax while you stay invested — compounding runs untaxed.
• Ignoring the ₹1.25L exemption. Spreading redemptions across financial years can keep more of your equity gains inside the annual exempt limit (this is the idea behind tax harvesting).
• Treating switches as tax-free. A switch from one scheme to another — or growth to IDCW — is a redemption in the eyes of tax law.
• Missing exit loads. A 1% exit load inside a year can stack on top of STCG tax.

The takeaway: know which clock your fund runs on, mind the 12-month line for equity, and remember each SIP instalment ages on its own. Tax rules change in Budgets — verify the current rates before you file. Nothing here is tax advice; for complex situations, consult a professional.
