Taxes aren’t supposed to feel exciting. They’re often bureaucratic, confusing, and — let’s face it — occasionally disappointing.
Every once in a while, though, a tax law change gives ordinary investors a real planning opportunity — something that can genuinely reduce what they owe. That’s what’s happening in 2026 with capital gains tax rules in India. A transitional break in the new Income Tax Bill, 2025 gives taxpayers a one‑time chance to use long‑term capital losses far more flexibly than usual. If you know about it — and act before the deadline — you can potentially save thousands.
This article explains what’s changing, why it matters, how to make the most of it, and the smart ways to plan around this window.
Why This Matters Right Now
Under the current tax regime (Income Tax Act, 1961), there are strict rules about capital losses:
- Short‑term capital losses (STCL) can be set off against both short‑term and long‑term gains.
- Long‑term capital losses (LTCL) can only be set off against long‑term capital gains (LTCG).
- Any unused losses can be carried forward for up to eight assessment years if your income tax return is filed on time.
That means if you had a big long‑term loss but only short‑term gains in subsequent years, you couldn’t use your long‑term loss to reduce your taxable short‑term gains. That restriction often left unutilized losses sitting on the books — a missed chance to cut tax bills.
But the new Income Tax Bill, 2025 changes this — temporarily and importantly.
The One‑Time Set‑Off Break Explained
Under Clause 536(n) of the new tax law, there’s a special transitional allowance:
➡️ Long‑term capital losses (LTCL), whether short‑term or long‑term, incurred up to March 31, 2026, and carried forward as of that date, can be set off against any capital gains — including short‑term gains — for tax years starting April 1, 2026 (AY 2026‑27) and up to eight subsequent years.
In plain language:
Instead of being limited to offsetting only long‑term gains, you can use those old long‑term losses to cancel out big short‑term gains too — for a limited window.
This is a fundamental shift from the old rule, and it’s aimed at smoothing the transition to the new law by letting past losses be more useful.
Why “One‑Time”?
This benefit is a transitional measure — part of the “repeal and saving” provisions of the new bill. It lets taxpayers take advantage of an older, less restrictive loss‑set‑off environment during the law changeover, but it doesn’t apply to losses incurred after March 31, 2026.
If you miss the window, future losses will continue to follow the standard rule: LTCL can only be offset against LTCG.
Why This Could Be a Big Deal for Taxpayers
If you’ve been holding onto large carried‑forward long‑term losses, you probably haven’t had full opportunities to use them, especially if your portfolio hasn’t generated equivalent long‑term gains.
Here’s why this window matters:
1. You Can Reduce Taxes on Short‑Term Gains
Short‑term gains — such as profits booked on assets held under a year — are typically taxed at higher effective rates and can add significantly to your tax bill. Using long‑term losses to neutralize those gains is normally not allowed. Under this special rule, it is — but only if your losses were realized before March 31, 2026.
2. You Get More Flexibility for Carry‑Forward Planning
Even if you don’t have long‑term gains now, this provision lets you strategically plan future years where you expect short‑term gains and apply old losses against them, reducing your overall tax burden.
3. It Strengthens Loss Harvesting as a Strategy
Loss harvesting — selling investments at a loss to offset gains — is normally limited by strict offset rules. This one‑time break expands that strategy’s reach for a few years.
Example: How This One‑Time Set‑Off Could Work
Imagine this scenario:
- You incurred a long‑term capital loss of ₹2,00,000 in 2024.
- You still carry this loss forward into FY 2026 because you didn’t have long‑term gains to use it against under the old rules.
- In FY 2027, you sell a short‑term asset and make a short‑term gain of ₹1,50,000.
Under the old tax law, your long‑term loss wouldn’t touch short‑term gains. You’d owe full tax on the ₹1,50,000.
Under the new one‑time transitional rule, however:
You can use the ₹2,00,000 long‑term loss against your ₹1,50,000 short‑term gain, reducing your taxable gain to ₹0 (and carry forward the remaining loss if needed).
That’s a huge benefit in years when your trading is more active or markets swing violently.
Must‑Know Conditions and Caveats
This one‑time set‑off window is not unconditional — here’s what to keep in mind:
Loss Must Be Realized Before March 31, 2026
Only losses computed up to March 31, 2026 qualify.
Beware: any long‑term losses you incur after that date will be subject to the standard rules, even if you think transitional provisions could apply.
Carry Forward Requires Timely ITR Filing
To use any carried forward loss, you must have filed your returns on time for the year in which the loss occurred. Late filing generally forfeits your right to carry forward those losses.
Only Set Off Against Capital Gains
Even under the new rule, capital losses — long or short — can only be set off against income categorized as “capital gains” under tax law. You cannot use them against wages, business income, interest, or dividends.
Carry Forward Still Time‑Limited
Even with the new rule, carried forward losses can be adjusted for up to eight assessment years after they are first computed. Plan your usage over future years accordingly.
Who Stands to Gain the Most?
This one‑time window especially benefits:
- Long‑term investors with unutilized losses from past years
- Active traders facing significant short‑term gains
- Tax‑aware planners who thought carried‑forward losses were “dead money”
- Investors who missed opportunities due to unlucky market timing
In volatile markets, the ability to cancel large short‑term gains with long‑term losses can be one of the most powerful legal tax strategies available — but only if you act while this provision is active.
How to Plan Your Moves Before the Deadline
This transitional set‑off window doesn’t last forever. Here’s how to make it count:
1. Check Your Loss Ledger Now
List all long‑term and short‑term capital losses you have carried forward so far. Categorize them by year and ensure returns were filed on time.
2. Match Expected Gains to Losses
Project likely gains for FY 2026–27 and beyond. If you expect short‑term gains that would otherwise be heavily taxed, consider realizing those gains in years where your carried forward losses can help.
3. Consider Partial Sell‑Offs for Planning
If you’re sitting on investments with potential losses, you might want to realize them before March 31, 2026 so they qualify under the transitional provision.
4. Balance Tax Planning With Investment Goals
Don’t let tax rules drive investment decisions alone. Loss harvesting or realization should still align with your broader portfolio strategy.
5. Track the Carry Forward Clock
Remember — you have only eight assessment years to use these losses once they’re set up under the new regime.
Real Stories: How This Could Change Lives
Consider two investors:
Priya’s Story: She invested in a sector that fell out of favour and booked significant long‑term losses in 2023–24. Until now, she’s been unable to fully use them because she had no matching long‑term gains. With the one‑time set‑off rule, she now can offset future short‑term gains — trimming what would have been a large tax bill to nearly zero, and significantly improving her net returns.
Amit’s Story: A trader who often books short‑term profits had no long‑term losses. By carefully buying and selling certain positions before March 31, 2026 to realize qualifying LTCL, he plans to use these losses against subsequent gains — shrinking taxes and improving cash flow.
These stories aren’t rare outliers. They reflect the real impact of transitional planning.
What Happens After This Window Closes?
Once the transition period lapses (i.e., for losses arising after March 31, 2026), the standard rules will apply again:
- Long‑term capital losses can only be offset against long‑term gains.
- Short‑term losses can be offset against short‑term and long‑term gains.
- Carry forward periods and filing deadlines remain as before.
That means the expanded flexibility is truly one‑time and temporary — it won’t stick around to become standard practice.
Final Thoughts
Tax planning often feels like navigating a maze with shifting walls. Transitional provisions like this one are rare — they appear once, demand action before a deadline, and then disappear.
If you’ve got long‑term capital losses on your balance sheet, this tax rule change gives you one of the best opportunities in years to make them work harder. Use it to offset short‑term gains, smooth your tax liabilities, and build better strategies for the next few tax years.
But it requires two things that many investors procrastinate on:
knowledge and timing.
This is one of those moments where being informed early can turn nominal losses into actual savings.

The way capital losses can be carried forward and set off was updated under the new Income Tax Bill 2025, introducing a transitional benefit that lets long‑term losses incurred up to March 31, 2026 be used against any capital gains — including short‑term gains — for up to eight assessment years. A detailed breakdown from Angel One explains how this one‑time relief works and why it represents a significant planning opportunity for investors looking to reduce their capital gains tax liabilities under the updated rules.
