Section 57 of Income Tax Act: Deductions Explained
31 December 2025

Introduction
Interest income from fixed deposits, bonds, and other financial instruments is commonly taxed under Income From Other Sources. However, many taxpayers are unaware that certain expenses can be deducted from such income under Section 57 of Income Tax Act.
This article explains deduction u/s 57, the scope of Section 57(1) of Income Tax Act, and how these provisions apply to interest and other income—purely from an educational standpoint.
What Is Section 57 of Income Tax Act?
Section 57 of Income Tax Act allows taxpayers to claim specific deductions from income taxed under the head Income From Other Sources.
In simple terms, this section permits:
deduction of certain expenses
provided they are incurred to earn that income
and are explicitly allowed under the Act
Only expenses listed under this section are eligible for deduction.
Types of Deductions Allowed Under Section 57
Broadly, deductions under Section 57 may relate to:
expenses incurred to earn interest income
expenses related to family pension
other expenses specifically permitted under the law
Each category has defined conditions and limitations.
Deduction u/s 57 for Interest Income
One of the most discussed applications is deduction u/s 57 against interest income.
This may include:
commission or remuneration paid to collect interest
expenses incurred wholly and exclusively for earning interest
However:
personal expenses are not allowed
only direct, income-related expenses qualify
The burden of proof lies with the taxpayer.
Section 57(1) of Income Tax Act Explained
Section 57(1) of Income Tax Act specifically allows deduction of:
any reasonable sum paid as commission or remuneration
for realizing interest or dividend income
Key points:
expense must be directly linked to income generation
indirect or estimated expenses are not permitted
documentation is essential to support claims
This clause is often misunderstood or overclaimed.
Expenses Not Allowed Under Section 57
Certain expenses are explicitly not deductible, including:
personal or household expenses
capital expenditures
expenses not directly related to earning income
Claiming ineligible expenses may lead to disallowance or scrutiny.
How Section 57 Differs From Other Deductions
Unlike deductions under Chapter VI-A:
Section 57 applies before computing total income
deductions are allowed only against specific income
there is no standard or blanket deduction
It is income-specific rather than investment-linked.
Reporting Section 57 Deductions in ITR
When filing income tax returns:
interest income is reported under “Income From Other Sources”
eligible deductions under Section 57 are reduced from gross income
supporting details may be required if queried
Accurate reporting helps avoid mismatches and notices.
Common Mistakes & Misconceptions
Misconception 1: All expenses related to income are deductible
Only expenses explicitly allowed under Section 57 qualify.
Misconception 2: Section 57 applies to salary or business income
It applies only to Income From Other Sources.
Misconception 3: Fixed percentage deduction is available
There is no flat or standard deduction for interest income.
Conclusion
Section 57 of Income Tax Act provides limited but important relief for taxpayers earning interest and certain other incomes. Understanding deduction u/s 57 and the scope of Section 57(1) of Income Tax Act helps ensure correct tax computation and compliance.
These deductions are specific, conditional, and require careful documentation.
