Section 57 of Income Tax Act: Deductions Explained

Saurabh Mukherjee 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.
