Section 270 of the Income Tax Act: Scrutiny Assessment

Introduction

Section 270 of the Income Tax Act provides a combined framework for processing income tax returns and conducting scrutiny assessments under the Income-tax Act, 2025. It covers permitted adjustments, taxpayer responses, scrutiny notices and the final determination of income, loss, tax demand or refund.

The Income-tax Act, 2025 applies from April 1, 2026. Under Section 270 of the Income Tax Act, sub-sections (1) to (7) mainly deal with return processing, while sub-sections (8) to (10) contain the main scrutiny provisions.

What Is Section 270 of the Income Tax Act?

Section 270 of the Income Tax Act allows the Income Tax Department to process a return using the information filed by the taxpayer. Where detailed verification is required, it also allows the authority to issue a scrutiny notice and pass an assessment order.

An intimation after return processing is not the same as a scrutiny assessment under Section 270 of the Income Tax Act.

Return Processing Under Section 270(1)

Section 270(1) permits adjustments for:

• Arithmetical errors
• Incorrect claims apparent from the return
• Prescribed inconsistencies with an earlier tax-year return
• Late-filed loss claims
• Audit-report items not considered in the return
• Specified Chapter VIII-C deductions claimed through a late return

The Department then calculates income or loss, tax, interest, fee, amount payable or refund due. Processing under Section 270 of the Income Tax Act is based mainly on return information. It is not a detailed examination of every supporting document.

Can an Adjustment Be Made Without Informing the Taxpayer?

No. Section 270(2) requires the taxpayer to be informed before an adjustment is made. The communication may be sent in writing or electronically.

The taxpayer has 30 days from the issue of the communication to respond. The response must be considered. If no response is received, the adjustment may be made. This protection under Section 270 of the Income Tax Act allows the taxpayer to explain a mismatch or valid claim.

Intimation Under Section 270 of Income Tax Act

An intimation may show adjusted income or loss, tax payable or refund due.

Section 270(3) also requires an intimation where declared loss is adjusted but no tax, interest or fee is payable and no refund is due. Section 270(3) is not the scrutiny provision.

Section 270(4) states that an intimation cannot be sent after nine months from the end of the financial year in which the return was furnished. Where no adjustment is made and no amount is payable or refundable, the acknowledgement may be treated as the intimation.

These rules form the processing part of Section 270 of the Income Tax Act.

What Is Scrutiny Assessment Under Section 270 of Income Tax Act?

Scrutiny assessment is a detailed examination of a selected return and its supporting evidence. The Assessing Officer may verify income, losses, expenses, deductions, capital gains, tax credits and other material particulars.

The purpose of scrutiny under Section 270 of the Income Tax Act is to ensure that the taxpayer has not:

• Understated income
• Computed an excessive loss
• Underpaid tax in any manner

A scrutiny notice does not automatically prove concealment or tax evasion. It means further verification is considered necessary.

Notice Under Section 270(8) of Income Tax Act

Section 270(8) allows the Assessing Officer or prescribed income tax authority to issue a notice where scrutiny is considered necessary or expedient.

The notice may require the taxpayer to attend the Assessing Officer’s office or produce evidence supporting the return. A notice under Section 270 of the Income Tax Act should be answered point by point with relevant documents.

Time Limit for a Scrutiny Notice

Section 270(9) states that a scrutiny notice cannot be served after three months from the end of the financial year in which the return was furnished.

For a return furnished during Financial Year 2026-27, the period is counted from March 31, 2027. The scrutiny notice limit under Section 270 of the Income Tax Act is different from the nine-month limit for a processing intimation.

Why May a Return Be Selected for Scrutiny?

Depending on available information and risk parameters, scrutiny may involve:

• Mismatch between the return and tax information
• A substantial refund or loss claim
• High-value transactions
• Foreign income or assets
• Capital gains differences
• Unusual deductions or expenses
• Inconsistency in turnover or tax credits

These are illustrative indicators, not automatic statutory grounds. Selection under Section 270 of the Income Tax Act does not itself establish wrongdoing. The statutory grounds remain possible understatement of income, excessive loss or underpayment of tax.

Scrutiny Assessment Process Under Section 270 of the Income Tax Act

Step 1: Notice

A notice is served under Section 270(8) within the limit prescribed under Section 270(9).

Step 2: Review

The taxpayer identifies the income, transaction, deduction, expense or loss selected for examination.

Step 3: Response

An issue-wise reply is filed with relevant and readable evidence.

Step 4: Further Inquiry

The Assessing Officer may seek evidence on specified points and consider other relevant material.

Step 5: Opportunity to Explain

Where an adverse addition is proposed, the taxpayer should be given an opportunity to explain the position under the applicable procedure.

Step 6: Final Order

The proceeding under Section 270 of the Income Tax Act is completed through an order under Section 270(10).

Documents Required for Scrutiny Assessment

Common records include:

• Return acknowledgement and computation
• Applicable tax information and tax credit statements
• Bank statements and books of account
• Financial statements and audit report
• Sales, purchase and expense records
• TDS certificates and tax-payment details
• Loan, property and capital-gains records
• Deduction, foreign income or foreign asset evidence

Documents submitted during proceedings under Section 270 of the Income Tax Act should be indexed, clearly named and linked to the relevant query.

Assessment Order Under Section 270(10) of Income Tax Act

Before passing the order, the Assessing Officer considers the evidence produced by the taxpayer, evidence required on specified points and relevant material gathered during the assessment.

The written order assesses the total income or loss and determines the amount payable or refund due.

The order under Section 270 of the Income Tax Act may accept the return, add income, disallow expenditure, reject a deduction, reduce a loss, create a demand or determine a refund. Section 270(10), not Section 270(3), completes scrutiny assessment.

Time Limit for Completing the Assessment

Section 270(9) sets only the deadline for serving the scrutiny notice. Section 286 governs the completion of an assessment under Section 270(10).

As a general rule, an order under Section 270 of the Income Tax Act must be passed within one year from the end of the financial year succeeding the relevant tax year. Special timelines, statutory exclusions or extensions may apply.

For Tax Year 2026-27, the general calculation ordinarily results in March 31, 2029, subject to applicable exclusions and extensions.

What Happens if the Taxpayer Does Not Respond?

Failure to comply with all terms of a notice under Section 270(8) may lead to a best judgment assessment under Section 271. The Assessing Officer may determine total income or loss using relevant available material.

Section 271 requires an opportunity of being heard before the best judgment assessment, subject to the specific exception stated in that provision. Non-compliance may result in deductions, expenses or losses remaining unsupported.

A notice under Section 270 of the Income Tax Act should therefore be answered within the deadline. Taxpayers can use Ebizfiling’s income tax notice reply service for notice review, response drafting and online submission.

What is Faceless Scrutiny Assessment?

Section 273 provides the framework for faceless assessment in specified cases, including an assessment under Section 270(10). Communications, documents and evidence are generally exchanged electronically through the registered account on the designated portal, subject to the provisions of Section 273.

Taxpayers should check their e-filing account and registered email regularly and preserve every acknowledgement. A response under Section 270 of the Income Tax Act must connect each explanation with supporting evidence.

Processing and Scrutiny: Key Difference

Both processes form part of Section 270 of the Income Tax Act, but scrutiny is wider and more detailed.

How to Reply to a Scrutiny Notice?

1. Check the section, tax year and deadline.
2. Read every query carefully.
3. Reconcile the return with books and tax records.
4. Prepare an issue-wise response.
5. Attach relevant and readable evidence.
6. Explain each material mismatch.
7. Respond to any proposed addition.
8. Preserve the portal acknowledgement.
9. Keep later explanations consistent.

A properly prepared response under Section 270 of the Income Tax Act can help explain genuine differences and reduce avoidable additions.
