- House Property loss: adjustable against other income only up to ₹2,00,000 per year in the Old Regime; completely blocked in the New Regime (Sec 115BAC). Balance carries forward 8 assessment years, usable only against future house property income — and HP loss survives even a belated return.
- Business loss (non-speculative): can offset house property, capital gains and other sources — never salary. Carry forward 8 years against future business income only.
- Speculative loss (intraday): only against speculative profits; carry forward just 4 years. Sec 35AD specified-business loss: only against another specified business; no time limit.
- Capital losses never leave the Capital Gains head. STCL sets off against both STCG and LTCG; LTCL only against LTCG. Both carry forward 8 years — identical in both regimes.
- Other Sources loss: adjustable against any head except salary, but any unabsorbed balance lapses (no carry forward). Lottery / betting / online-gaming losses can never be set off or carried forward.
- Golden rule: to carry forward business, speculative or capital losses, file your ITR on or before the Sec 139(1) due date — a belated return legally voids the carry-forward (house property loss is the lone exception).
Every year lakhs of taxpayers lose legitimate tax savings simply because they do not know the set-off and carry forward rules — which loss can be adjusted against which income, what the ₹2 lakh house-property cap means, why a business loss can never touch your salary, and why filing your return one day late can permanently destroy an eight-year carry-forward benefit. This guide is the complete, plain-English breakdown of the loss adjustment rules under the Income Tax Act, 2025 (effective 1 April 2026), for every head of income, in both the Old Tax Regime and the New Tax Regime (Section 115BAC) — with a master summary table you can bookmark.
By the numbers: Under the Income Tax Act, 2025 (536 sections, effective 1 April 2026), house-property loss set-off against other income is capped at ₹2,00,000 per year in the Old Regime and ₹0 in the New Regime, while unabsorbed business and capital losses carry forward for up to 8 assessment years — but only if the ITR is filed by the Section 139(1) due date.

| Speculative (intraday) | No — speculative profits only | 4 AYs |
| Capital loss (STCL / LTCL) | Never — stays inside Capital Gains | 8 AYs |
| Other Sources (regular) | Yes, except salary | None — lapses |
| Lottery / betting / gaming | Never | Never |
“Most carry-forward claims fail for one avoidable reason — the return was filed after the Section 139(1) due date. Set-off planning starts with filing on time, not with the loss itself.” — CA Juber Attar, TaxFetch e-CA Tax Expert
What is set-off and carry forward of losses?
Set-off means adjusting a loss from one source or head of income against profit from another in the same financial year. It happens in two stages:
- Intra-head set-off: loss from one source adjusted against profit from another source under the same head (e.g. loss from one rented flat against rent from another).
- Inter-head set-off: the remaining loss adjusted against income under a different head (e.g. house-property loss against salary) — subject to strict restrictions explained below.
Carry forward means transporting whatever loss remains unadjusted to future years, to be set off against specified income later — each type of loss has its own time limit (8 years, 4 years, unlimited, or none at all).
1. House Property loss — the ₹2 lakh cap and the New Regime block
A house-property loss usually arises from home-loan interest exceeding the rental income (or the annual value of a self-occupied home).
- Intra-head: loss from one property fully adjusts against rental profit from another property.
- Inter-head (Old Regime): the balance can be adjusted against salary, business income, capital gains and other sources — but only up to ₹2,00,000 per year.
- Inter-head (New Regime, Sec 115BAC): completely prohibited. Your HP loss cannot reduce any other head at all.
- Carry forward: up to 8 assessment years, but once carried forward it can only offset future house property income.
- Unique relaxations: HP loss can be carried forward even if the ITR is belated, and old HP losses remain carry-forwardable after you switch to the New Regime (they will still only reduce future rental profits).
Example: Old Regime, salary ₹10,00,000, HP loss ₹3,50,000 → only ₹2,00,000 adjusts against salary this year; the balance ₹1,50,000 carries forward for up to 8 years against future rental income. In the New Regime, the entire ₹3,50,000 carries forward and salary stays fully taxable.
2. Business & Profession losses — three separate buckets
A. Regular (non-speculative) business or professional loss
- Intra-head: fully adjustable against any business profit, including speculative or specified-business profits.
- Inter-head: adjustable against house property, capital gains and other sources — never against salary income, under any circumstances.
- Carry forward: up to 8 assessment years, only against future business / professional income.
B. Speculative business loss (e.g. intraday equity trading)
- Completely quarantined: it cannot offset regular business profit or any other head.
- Set-off only against speculative business profit; carry forward only 4 assessment years.
C. Specified business loss (Section 35AD-type — cold chains, warehouses)
- Set-off only against profit from another specified business.
- Carry forward: no time limit (indefinite).
- New Regime note: opting for the New Regime blocks the accelerated specified-business capital deductions, effectively preventing new losses of this type from arising.
3. Capital losses — a strict one-way ecosystem
Capital gains operate as a sealed compartment: no capital loss can ever be adjusted against salary, house property, business or other sources — and no outside loss rule changes that.
- Short-Term Capital Loss (STCL): flexible inside the head — sets off against both STCG and LTCG. Carry forward 8 assessment years.
- Long-Term Capital Loss (LTCL): restricted — sets off only against LTCG, never against STCG. Carry forward 8 assessment years.
- Regime impact: none — the STCL / LTCL mechanics are identical in the Old and New Regimes.
Remember the listed-equity numbers while planning: LTCG on equity is exempt up to ₹1,25,000 a year and taxed at 12.5% beyond that — so a smart harvest of LTCL against taxable LTCG can save real tax.
4. Income from Other Sources loss — use it or lose it
- Intra-head: regular IFOS losses (e.g. interest expense exceeding dividend income) adjust against other regular IFOS streams.
- Inter-head: adjustable against any head except salary.
- No carry forward: whatever remains unadjusted at year-end simply lapses.
- Race horses: loss from owning / maintaining race horses adjusts only against the same activity; carry forward 4 assessment years.
- Casual income insulation: losses from lotteries, crossword puzzles, card games, betting or online games can never be set off against anything, and can never be carried forward. Equally, no other loss can be adjusted against such casual winnings (taxed flat at 30%).

| Lottery / betting / online games | Never | Never | Never | — | N/A |
Critical operational rules and deadlines
The filing mandate — the rule that voids everything else
To carry forward any business, speculative, specified-business or capital loss, you must file your Income Tax Return on or before the original due date under Section 139(1) on the Income Tax portal. A belated return legally voids these carry-forward benefits — the loss dies with the missed deadline. The lone exception is house property loss, which survives a belated return.
The mandated order of adjustment for business income
- First: current-year depreciation and scientific-research expenditure.
- Second: brought-forward business losses from earlier years.
- Third: unabsorbed depreciation (which itself has no time limit).
What happens to old losses when you switch regimes?
Carried-forward house property losses survive a switch to the New Regime, but remain usable only against future rental profits. Capital-loss mechanics are unchanged by the regime. The real casualty of the New Regime is the current-year inter-head HP set-off (blocked entirely) — which is why homeowners with large home-loan interest should always compare both regimes before choosing.
The TaxFetch Income Tax Calculator applies every rule on this page automatically — the ₹2 lakh HP cap, the New Regime block, business-loss-vs-salary prohibition, capital-loss quarantine and IFOS lapse — and shows a dedicated “Set-off & Carry Forward of Losses” section in your result and PDF report, side-by-side for both regimes.
Calculate my tax with loss set-off →Frequently Asked Questions
1. Can house property loss be set off against salary in the New Tax Regime?
No. Under the New Regime (Section 115BAC), inter-head set-off of house property loss is completely prohibited — it cannot reduce salary or any other head. In the Old Regime, it can, but only up to ₹2,00,000 per year; the balance carries forward up to 8 assessment years against future house property income only.
2. Can business loss be adjusted against salary income?
Never. A business or professional loss cannot be set off against salary under any circumstances, in either regime. It can offset house property income, capital gains and other sources, and the balance carries forward 8 years against future business income.
3. Can short-term capital loss be set off against salary or business income?
No. Capital losses never leave the Capital Gains head. STCL can be set off against both STCG and LTCG; LTCL only against LTCG. Unabsorbed amounts carry forward for up to 8 assessment years — provided the return is filed by the due date.
4. What happens if I file my ITR late — do I lose the carry forward?
Yes, for most losses. Business, speculative and capital losses can be carried forward only if the return is filed on or before the Section 139(1) due date. The one exception is house property loss, which can be carried forward even from a belated return.
5. For how many years can each loss be carried forward?
House property, non-speculative business, STCL and LTCL — 8 assessment years. Speculative (intraday) loss and race-horse activity loss — 4 years. Specified-business (35AD-type) loss and unabsorbed depreciation — no time limit. Regular Other Sources loss — zero: it lapses the same year.
6. Can losses be adjusted against lottery or online gaming winnings?
No. Casual income (lottery, crossword, card games, betting, online games) is fully insulated — taxed flat at 30% with no loss adjustment allowed against it, and losses from these activities can never be set off or carried forward either.
7. How do I check my own set-off and carry forward position?
Use the free TaxFetch Income Tax Calculator — enter your income heads (including negative amounts for losses) and it automatically applies every rule above, shows exactly how much was set off this year, what carries forward, and what lapses — for the Old and New Regime side by side, in the result and the downloadable PDF report.
Conclusion
The set-off and carry-forward framework under the Income Tax Act, 2025 rewards two things: knowing which pocket each loss can come out of, and filing on time. Keep the master table above bookmarked, remember the three absolutes — capital losses never leave their head, business losses never touch salary, and casual income absorbs nothing — and let the TaxFetch Income Tax Calculator do the mechanical work: it applies the ₹2 lakh cap, the regime rules and the carry-forward math automatically and prints the full working in your PDF report.
