Set-Off and Carry Forward of Losses Under the Income Tax Act, 1961 – A Comprehensive Guide

The Income Tax Act, 1961, as amended by the Finance Act, 2026, lays down a structured framework governing how losses incurred by an assessee can be adjusted against income — either in the same year or in subsequent years. Understanding these provisions is essential for effective tax planning and compliance. This guide walks through every significant aspect of loss set-off and carry forward, including special categories of losses, procedural requirements, and restrictions applicable in specific circumstances.

Foundational Principle: Losses from Exempt Sources Are Not Adjustable

Before diving into the mechanics of set-off and carry forward, it is important to understand a foundational rule: losses arising from a source whose income is exempt from tax cannot be set off against any income that is chargeable to tax.

For instance, agricultural income enjoys exemption under the Income Tax Act, 1961. Consequently, if an assessee suffers a loss from agricultural operations, that loss cannot be applied to reduce any other taxable income. The logic is straightforward — if gains from a source are not brought within the tax net, losses from that very source cannot claim any benefit against taxable streams.

Understanding Intra-Head Adjustment of Losses

What Is Intra-Head Adjustment?

When an assessee earns income from multiple sources falling under the same head of income, a loss from one source can be adjusted against income from another source within that same head. This mechanism is called intra-head adjustment.

To illustrate: if Mr. Sharma runs two businesses — Business X (profitable) and Business Y (loss-making) — the loss from Business Y can be set off against the profit from Business X, since both fall under the head "Profits and Gains of Business or Profession."

Key Restrictions on Intra-Head Adjustment

Several important restrictions govern intra-head adjustments:

  1. Speculative business losses can only be set off against income from another speculative business. However, a loss from a non-speculative business can be set off against income from a speculative business.

  2. Long-term capital loss (LTCL) can only be adjusted against long-term capital gains (LTCG). On the other hand, short-term capital loss (STCL) enjoys greater flexibility and can be set off against both short-term and long-term capital gains.

  3. No loss of any kind is permitted to be set off against income derived from winnings from lotteries, crossword puzzles, horse races, card games, or any other form of gambling or betting.

  4. Losses from the business of owning and maintaining race horses are ring-fenced and can only be adjusted against income from the same activity — i.e., owning and maintaining race horses.

  5. Losses from specified businesses covered under Section 35AD — which includes businesses such as setting up cold chain facilities, operating warehousing infrastructure for agricultural produce, and developing housing projects — can only be set off against income from other specified businesses under that section.

Understanding Inter-Head Adjustment of Losses

What Is Inter-Head Adjustment?

Once intra-head adjustment is completed (wherever applicable), the next layer of adjustment is inter-head adjustment. This allows an assessee to set off a loss arising under one head of income against income arising under a different head.

A common example is adjusting a loss under the head "Income from House Property" against income under the head "Salaries."

Restrictions Applicable to Inter-Head Adjustment

Inter-head adjustment is subject to several restrictions, which must be carefully observed:

  1. Intra-head adjustment must be completed before proceeding to inter-head adjustment.

  2. Speculative business losses cannot be set off against income under any other head, though non-speculative business losses can be used against speculative income.

  3. Capital losses — whether short-term or long-term — cannot be set off against income falling under any head other than "Capital Gains."

  4. Losses cannot be adjusted against lottery, gambling, betting, or race winnings under any circumstances.

  5. Race horse business losses remain restricted solely to income from that specific activity.

  6. Losses from Section 35AD specified businesses are similarly ring-fenced and cannot be adjusted against any income from outside that category.

  7. Business and profession losses cannot be set off against salary income.

  8. Loss under "Income from House Property" is permitted to be adjusted against other heads of income only up to a ceiling of Rs. 2,00,000 per assessment year.

  9. Any house property loss that remains unabsorbed beyond this limit can be carried forward to subsequent years under Section 71B.

Carry Forward of Unadjusted Losses

When losses remain unadjusted even after completing both intra-head and inter-head adjustments, the Income Tax Act, 1961 allows such losses to be carried forward to future years. Different provisions govern different categories of losses.
