Capital Loss Set-Off: STCL vs LTCL Matrix for 2026

CA Nikhil Gupta·Aug 2026·7 min readIncome Tax

Short-term capital loss can generally be set off against short-term or long-term capital gains.

Short-term capital loss can generally be set off against short-term or long-term capital gains. Long-term capital loss can be set off only against long-term capital gains. Unabsorbed eligible capital loss can be carried forward for eight years only with a timely loss return.

Legal or Computational Framework

What the search phrase hides

The phrase capital loss offsetting against capital gain compresses several legal questions into one line. The outcome cannot be trusted until the page identifies the relevant person, transaction, period, source document and statutory exception. A high-quality calculator should therefore show why an amount was accepted or rejected instead of displaying a black-box answer.

Governing framework

Character must be preserved transaction by transaction. Current-year set-off and future carry-forward are different questions. VDA losses are ring-fenced and cannot be set off or carried forward. Share buyback, special mutual-fund and transition items require separate classification.

Tax Year 2026–27 means income earned from 1 April 2026 under the Income-tax Act, 2025. AY 2026–27 relates to FY 2025–26 and remains under the Income-tax Act, 1961.

Step-by-step method

  1. Compute gains/losses lot-wise.
  2. segregate STCL, LTCL and barred losses.
  3. set off within the legally permitted matrix.
  4. use an optimisation order where several rates exist.
  5. record residual loss by origin year.
  6. file the return on time.

Worked example

STCL ₹2 lakh, listed-equity STCG ₹80,000 and property LTCG ₹1.5 lakh. STCL can absorb both, leaving ₹30,000 STCL. If the return is timely, the balance can be carried forward. An LTCL of ₹2 lakh could not absorb the STCG.

The example is intentionally presented as a calculation trail. The final result must be recomputed when a date, residence test, holding period, asset classification, employee category, notification, treaty or source document changes.

Rate is the final step, not the first

Capital-gain pages often begin with a percentage and therefore miss the decisive work: identifying the asset, statutory acquisition date, transfer event, cost rule, holding period and special deeming provision. A 12.5%, 20% or 30% rate is meaningful only after the gain has been correctly characterised. TDS or STT does not perform that classification.

Transaction-level audit trail

The computation should retain each acquisition lot, corporate action, cost adjustment, transfer expense, loss set-off and exemption allocation. Aggregation should occur only after character and rate are determined. This matters where a single financial year contains equity STCG, equity LTCG, property gain, VDA transactions and brought-forward losses, each with a different tax treatment.

Edge cases that change the answer

Cross-check before filing, paying or claiming

  1. Confirm that the legal year and transaction date match the rate or rule used.
  2. Reconcile gross consideration, gross income or gross benefit—not merely the net bank receipt.
  3. Distinguish a deduction or exemption from TDS, TCS, withholding or an employer provision.
  4. Keep the original source document and a calculation worksheet.
  5. Review interactions with losses, special rates, surcharge, cess, treaty relief or GST.
  6. Record the official source and its effective date in the calculation output.

Calculator design standard

The Finin2min calculator linked below should retain the user's original input, display the legally accepted amount, identify the formula and rate, and state the reason for every cap or rejection. Rate-sensitive output should show the applicable tax year or effective date. Where facts cannot be automated—such as treaty PE, beneficial ownership, continuity of service or property valuation—the tool should flag professional review rather than make an unsupported assumption.

What Generic Pages Miss

  • Setting LTCL against STCG.
  • Carrying loss after a late return.
  • Netting crypto loss.
  • Using broker net P&L without lot classification.
  • Forgetting prior-year expiry.

Generic pages also tend to mix a tax credit with a deduction, a labour entitlement with an income-tax exemption, or a supply value with business income. That can produce a mathematically neat but legally wrong result.

Finin2min Summary

Short-term capital loss can generally be set off against short-term or long-term capital gains. Long-term capital loss can be set off only against long-term capital gains. Unabsorbed eligible capital loss can be carried forward for eight years only with a timely loss return.

Finin2min rule: classify first, calculate second, and document every assumption.

Frequently Asked Questions

Can STCL offset LTCG? â–¼
Yes, generally.
Can LTCL offset STCG? â–¼
No. LTCL is restricted to LTCG.
How long can capital loss be carried forward? â–¼
Eight succeeding years, subject to timely filing and other conditions.
Can a late return preserve carry-forward? â–¼
Generally no for capital loss; the loss return must meet the due-date condition.
Can crypto loss reduce share gain? â–¼
No. VDA loss is specifically barred from set-off and carry-forward.
Which gain should STCL offset first? â–¼
The law permits eligible categories; tax optimisation should be documented where rates differ.
