Section 271 Income Tax Act 2025: When Can Best Judgment Assessment Be Made?

Section 271 authorises a best judgment assessment when specified failures to file an income-tax return or comply with statutory notices prevent the ordinary assessment process from proceeding. It also prescribes procedural safeguards for the assessee.

What is best judgment assessment under Section 271?

Best judgment assessment is a statutory assessment made by the Assessing Officer on the basis of relevant material gathered where a person has failed to comply with specified return-filing or notice requirements. It is not an unrestricted power to estimate income arbitrarily. The Assessing Officer must take into account relevant material, assess the total income or loss to the best of his judgment, and determine the amount payable.

Section 271 contains three subsections. Subsection (1) identifies the defaults and the assessment power; subsection (2) sets out the show-cause notice requirement; and subsection (3) provides a specific exception to that notice requirement.

When can the Assessing Officer invoke Section 271(1)?

These grounds relate to the return of income, inquiry before assessment, and scrutiny assessment. A mere difference of opinion about a tax claim does not, by itself, establish one of the specific defaults listed in Section 271(1).

What procedure must the Assessing Officer follow?

  1. Identify a statutory default: The case must fall within one of the circumstances in Section 271(1).
  2. Gather and consider relevant material: The Assessing Officer must base the assessment on material available, rather than unsupported speculation.
  3. Provide an opportunity of being heard: Section 271(1) expressly requires an opportunity of hearing before the assessment is made.
  4. Serve a show-cause notice: Under Section 271(2), and subject to subsection (3), the Assessing Officer must serve notice specifying the date and time for the assessee to explain why best judgment assessment should not be made.
  5. Pass an assessment: The officer assesses total income or loss and determines the sum payable on that basis.

Important exception: Under Section 271(3), the separate opportunity referred to in Section 271(2) need not be given if a notice under Section 268(1) was issued before the assessment. This exception concerns the specific subsection (2) opportunity; Section 271(1) must also be read in full, including its requirement to give the assessee an opportunity of being heard.

Section 271 explained subsection by subsection

Section 271(1): Grounds and power to assess

The provision applies when a person fails to file the specified return, fails to comply with a notice or direction under Section 268, or fails to comply with a scrutiny notice under Section 270(8). The Assessing Officer must consider the relevant materials gathered and determine total income or loss and the resulting amount payable after giving an opportunity of being heard.

Section 271(2): Show-cause notice

Before making a best judgment assessment, the Assessing Officer must, subject to Section 271(3), serve a notice asking the assessee to show cause on the specified date and at the specified time why the assessment should not be completed to the best of the officer's judgment. The taxpayer should respond with facts, records and explanations within the prescribed opportunity.

Section 271(3): Exception to separate show-cause opportunity

The additional opportunity contemplated in Section 271(2) is not mandatory where a notice under Section 268(1) was already issued before the assessment under Section 271. Whether the statutory requirements and principles of natural justice were satisfied depends on the notice history and circumstances of the particular case.

Relevant statutory terms and concepts

Assessing Officer: The income-tax authority vested with jurisdiction to make the assessment under the applicable provisions of the Act.
Assessee: The person whose income, loss or tax liability is subject to the assessment process; the statutory meaning must be read with the Act's definition provisions.
Return of income: The income-tax return required or permitted under Section 263, subject to applicable filing rules.
Inquiry before assessment: Proceedings under Section 268 involving specified notices, documents, information or directions.
Scrutiny notice: A notice under Section 270(8), requiring compliance with the terms specified in it.
Best judgment: A reasoned assessment using relevant material available to the Assessing Officer after the applicable statutory procedure, not a licence for arbitrary additions.
Opportunity of being heard: A procedural safeguard allowing the assessee to present an explanation and supporting material before the adverse assessment is made, subject to the precise statutory scheme.

Practical examples

Example 1 - Return not filed: A person required to furnish a return under Section 263 fails to do so. If the requirements of Section 271(1)(a) are satisfied, the Assessing Officer may proceed with a best judgment assessment after following the applicable procedure.

Example 2 - Records not produced: A business receives a lawful notice under Section 268(1) requiring specified books of account and does not comply with its terms. Section 271(1)(b) may become applicable. The officer must still consider relevant material and the hearing requirements.

Example 3 - Scrutiny notice ignored: An assessee files a return but fails to comply with all the terms of a notice under Section 270(8). The Assessing Officer may assess under Section 271(1)(c), subject to statutory safeguards.

Example 4 - Earlier inquiry notice: Where a Section 268(1) notice was issued before the best judgment assessment, Section 271(3) removes the need for the separate opportunity described in Section 271(2). The assessee should examine the actual notices and hearing record before challenging procedural compliance.

What should a taxpayer do after receiving a notice?

  • Check the exact section, date, response deadline and information requested.
  • File a complete and timely response, with supporting books, statements and reconciliations.
  • Explain any genuine inability to comply and request a reasonable opportunity where appropriate.
  • Retain proof of submission, acknowledgments and communications.
  • Review the eventual order, the material relied on and available statutory remedies, including appeal where maintainable.

The ordinary statutory time limits for assessment and applicable remedies arise under other provisions of the Act; Section 271 itself does not prescribe a universal fixed number of days for responding to every show-cause notice.
