Section 112 of the Income-tax Act, 2025 — Carry Forward and Set Off of Business Loss

In plain language

What Section 112 of the Income-tax Act, 2025 actually says

Section 112 of the Income-tax Act, 2025 governs the carry forward and set off of business loss. In plain words: if in a year your business or profession runs at a loss and that loss cannot be fully absorbed against your other income in the same year, the leftover loss does not vanish. You are allowed to carry it forward and set it off against the profits of any business or profession you carry on in the following years, up to a maximum of eight tax years. This section is the direct successor to Section 72 of the old Income-tax Act, 1961, and the core rules have been retained almost identically.

Who it applies to

• Everyone with a business or profession loss — individuals, HUFs, firms, LLPs, companies and other assessees who compute income under the head "Profits and gains of business or profession".
• Non-speculative business only. Losses from a speculation business are specifically excluded from Section 112 — they follow a separate provision.
• It covers a normal trading/manufacturing/professional loss (for example, a shop, a consultancy, a factory, a freelancer) that remains after intra-year adjustments.

The key conditions and limits

• Eight-year limit. A business loss can be carried forward for a maximum of eight tax years immediately following the year in which the loss was first computed. If it is still unabsorbed after eight years, it lapses.
• Set off only against business income. A carried-forward business loss can only be set off against profits and gains of business or profession in later years — not against salary, house property, capital gains or other income.
• Continuity of the same business is NOT required. You can set the loss off against profits of any business or profession you carry on later, even if the loss-making business has been discontinued. The business must simply be carried on by the same assessee.
• Return must be filed on time. This condition sits in the general filing provision (Section 108 of the 2025 Act, the successor to Section 80 of the 1961 Act): to carry forward a business loss you must have filed your income-tax return on or before the due date. A late return means you lose the right to carry forward.

Order of set off — an important detail

Business loss gets priority over unabsorbed depreciation-type allowances. Where carried-forward allowances such as unabsorbed depreciation under section 33(11) or certain capital-expenditure allowances under section 45(7) are also waiting to be adjusted, effect must first be given to the current and brought-forward business loss under Section 112. This matters because a plain business loss lapses after 8 years, while unabsorbed depreciation can be carried forward indefinitely — so using the time-limited loss first is to the taxpayer's advantage, and the law builds this in.

How it interacts with related sections

• Section 109 (intra-head / inter-head set off in the same year) is applied first. Only the loss that survives that stage moves into Section 112 for carry forward.
• Speculation loss and specified-business loss are dealt with under their own carry-forward sections, not here.
• Unabsorbed depreciation continues under its own mechanism (section 33(11)) with no eight-year cap.

Practical implications for taxpayers

• File on time, every time. Even in a loss year, filing your return by the due date is what preserves the loss for future set off.
• Track each year's loss separately. The eight-year clock starts from the specific year the loss was computed, so a schedule of "loss by year" is essential.
• Plan profitable years. Because the loss expires, businesses expecting a turnaround should time deductions and income to absorb older losses before they lapse.
• Restructuring cautions. Companies undergoing amalgamation, demerger or change in shareholding face additional restrictions under separate anti-abuse provisions, which override the general freedom in Section 112.
