The concept of set-off and carry forward of losses allows taxpayers to adjust their losses against income, thereby reducing tax liability. It is an important tax planning tool under the Income Tax Act, 1961.
What is Set-off of Losses?
Set-off means adjusting losses against income in the same financial year.
Types of Set-off:
- Intra-head Set-off
Adjust loss from one source against income from another source under the same head
(e.g., business loss vs another business profit) - Inter-head Set-off
Adjust loss under one head against income from another head
(e.g., business loss against salary income – subject to rules)

If losses cannot be fully adjusted in the same year, they can be carried forward to future years and set off against future income.
