How-to capital loss offset tax-loss harvesting

How to set off mutual fund capital losses in ITR

From WebNotes, a public knowledge base. Last updated . Reading time ~4 min.

Setting off mutual fund capital losses against gains reduces your taxable LTCG / STCG. Two key rules govern: within-head offset (Section 70) and cross-head offset (Section 71). For most retail MF investors, only within-head matters: losses from MFs offset gains from MFs (or other capital assets), not salary income.

Step-by-step procedure

See the procedure infobox above.

Within-head offset rules (Section 70)

Loss typeCan offset against
Short-term capital loss (STCL)Any other STCG (equity or non-equity) OR LTCG
Long-term capital loss (LTCL)Only LTCG (cannot offset STCG)

Rationale: STCL is treated more flexibly because STCG is taxed at higher rates; LTCL is restricted to maintain symmetry.

Cross-head offset (Section 71)

Loss typeCross-head offset allowed?
Capital losses (STCL or LTCL)No (cannot offset salary, business, or other heads)

This is why “tax-loss harvesting” benefits are limited to capital gains; you can’t reduce your salary tax through MF losses.

Section 94(7) wash-sale rule

To prevent artificial loss creation:

If you:

  1. Buy MF units, then
  2. Receive IDCW (declared within 3 months pre / 3 months post), then
  3. Sell the units within 3 months pre / 3 months post the IDCW record date,
  4. The capital loss to the extent of IDCW is disallowed.

Effectively, you can’t claim a loss equal to a dividend you just collected from the same scheme. Plan tax-loss harvesting to avoid this trap.

Worked example

FY 2024-25 capital activity:

  • Equity MF A: LTCG Rs 1 lakh.
  • Equity MF B: LTCL Rs 60,000.
  • Debt MF C: STCG Rs 50,000.
  • Equity MF D: STCL Rs 30,000.

Set-off computation:

  1. LTCG Rs 1L vs LTCL Rs 60k = Net LTCG Rs 40k.
  2. STCG Rs 50k vs STCL Rs 30k = Net STCG Rs 20k.

LTCG (within exemption Rs 1.25L): Tax Rs 0. STCG Rs 20k at 20%: Tax Rs 4,000.

Total: Rs 4,000 vs original Rs 12,500 + STCG. Savings: ~Rs 8,500.

Carry-forward to subsequent FYs

Net unutilised capital loss after current-FY offset:

  • Reported in Schedule CFL.
  • Carried forward for 8 subsequent FYs.
  • Used against future capital gains.

Long-term losses carry over as long-term. Short-term losses carry over as short-term.

Practical tax-loss harvesting

StrategyWhen
Realise embedded losses at FY-endIf anticipated gains in next FY
Wash-sale protectionDon’t re-buy same scheme in 3-month window
Switch to similar schemeMaintain exposure with different AMC’s scheme
Hold during recoveryIf conviction in scheme remains
