Different Types of Income Tax Notices in India

The Income Tax Department issues different types of notices and communications to taxpayers for verification of income tax returns, seeking information, scrutiny assessment, reassessment, rectification, recovery of tax demands and penalty proceedings.

Receiving an income tax notice does not automatically mean that additional tax is payable or that the taxpayer has committed a default. However, the type of income tax notice, statutory section and applicable deadline determine the action required.

From 1 April 2026, the Income-tax Act, 2025 introduced a reorganised framework with revised section numbers. Proceedings relating to earlier tax periods may continue to be governed by the Income-tax Act, 1961 under the applicable transitional provisions.

This guide explains the different types of income tax notices in India, their meaning, relevant provisions under both Acts, possible consequences and important precautions.

If you have already received a notice, see our guide on How to Respond to an Income Tax Notice in India. For professional representation, visit our Income Tax Assessment and Litigation Services page.

What Are the Main Types of Income Tax Notices in India?

Income tax notices may be issued at different stages of the tax compliance and assessment process. Some require correction of an income tax return, while others seek supporting documents, initiate scrutiny or reassessment, or communicate an outstanding demand.

Common categories include:

• Defective income tax return communications.
• Prima facie adjustment notices during return processing.
• Inquiry and information notices.
• Scrutiny assessment notices.
• Show cause notices before best judgment assessment.
• Faceless assessment communications.
• Reassessment show cause notices and reassessment notices.
• Rectification notices and related communications.
• Notices of demand.
• Penalty show cause notices.

Important distinction: Not every departmental communication is legally a notice. The Department may issue an intimation, letter, order or show cause communication. Its legal implications depend on the governing provision and facts of the case.

Income-tax Act, 1961 vs Income-tax Act, 2025: Notice Sections

The Income-tax Act, 2025 came into force on 1 April 2026. It reorganised and renumbered many provisions that taxpayers were familiar with under the Income-tax Act, 1961.

For example, a scrutiny notice commonly associated with section 143(2) under the earlier Act broadly corresponds to a notice under section 270(8) of the new Act.

The distinction between the two Acts depends on the relevant tax period and the transitional provisions, not merely the date on which a communication is received.

• Assessment Year 2026-27: Relates to Financial Year 2025-26 and continues under the relevant provisions of the Income-tax Act, 1961.
• Tax Year 2026-27: Relates to income earned from 1 April 2026 to 31 March 2027 under the Income-tax Act, 2025.
• Earlier assessment years: Proceedings may continue under the old Act in accordance with the repeal and savings framework, including section 536 of the Income-tax Act, 2025.

Taxpayers can refer to the official Income-tax Act, 2025 and the Income Tax Department’s guidance on the transition between the two Acts.

Quick Comparison of Common Income Tax Notice Sections

The following table identifies the principal notices and communications frequently encountered in income-tax proceedings.

Note: The table is a broad comparison of corresponding provisions. It does not mean that all procedural conditions, limitation periods and legal consequences are identical under both Acts. Furthermore, faceless assessment is a procedural framework rather than a single standalone notice.

Defective Income Tax Return Notice — Section 139(9) / Section 263(7)

A defective return communication is issued where the filed income tax return does not satisfy the prescribed requirements.

Common issues may include incomplete schedules, inconsistent information or missing particulars required for a valid return.

Time Limit and Consequences

Under section 263(7) of the Income-tax Act, 2025, the taxpayer is ordinarily given fifteen days from the date of intimation to rectify the defect, or a further period permitted on an application.

If the defect is not rectified within the permitted period, the return may be treated as invalid, subject to the applicable statutory provisions. The Assessing Officer may condone a delayed rectification in circumstances permitted by law.

The corresponding provision under the Income-tax Act, 1961 is section 139(9).

Practical recommendation: Identify the exact defect mentioned in the communication and correct it through the prescribed e-Filing process rather than simply submitting a general written explanation.

Intimation and Prima Facie Adjustment — Section 143(1) / Section 270(1)

Income tax returns are processed electronically, and an intimation may communicate the outcome of processing, including a refund, tax demand or adjustment.

Under the Income-tax Act, 1961, section 143(1) deals with processing of returns. The corresponding processing framework under the Income-tax Act, 2025 is section 270(1).

When Is a Prima Facie Adjustment Proposed?

A proposed adjustment may arise from matters covered by the applicable statutory provision, such as specified apparent errors or information differences.

Where the law requires an opportunity before making the adjustment, the taxpayer should examine the proposed variation and provide agreement or disagreement with relevant reasons and supporting details.

A processing intimation is not the same as a detailed scrutiny assessment. It should also not be assumed that every intimation requires the taxpayer to submit a reply.

If a processing adjustment results in an incorrect demand, the appropriate response, rectification or appellate remedy depends on the circumstances.

Inquiry Notice Before Assessment — Section 142(1) / Section 268(1)

An inquiry notice is issued when the Assessing Officer requires information, accounts, documents or other particulars relevant to determining the taxpayer’s income.

Section 142(1) of the Income-tax Act, 1961 broadly corresponds to section 268(1) of the Income-tax Act, 2025.

Depending on the circumstances, an inquiry notice may seek:

• A return of income where the statutory requirements are satisfied.
• Books of account and financial statements.
• Bank statements and transaction details.
• Explanations of loans, advances or deposits.
• Sales, purchases and expense supporting documents.
• Reconciliation of information appearing in tax and financial records.

Does an Inquiry Notice Mean Additional Tax Is Payable?

No. An inquiry notice is generally an information-gathering step. Whether any adjustment or addition is ultimately made depends on the relevant evidence, statutory requirements and assessment proceedings.

However, failure to comply may have consequences under the applicable law, including the possibility of best judgment assessment where statutory conditions are satisfied.

For a detailed explanation of the response procedure, refer to How to Prepare and Submit an Income Tax Notice Reply.

Scrutiny Assessment Notice — Section 143(2) / Section 270(8)

A scrutiny notice indicates that the income tax return has been selected for more detailed examination.

Under the Income-tax Act, 1961, section 143(2) governs a scrutiny notice. The corresponding notice provision under the Income-tax Act, 2025 is section 270(8).

Scrutiny proceedings may involve examination of:

• Income reported in the return.
• Turnover and other business receipts.
• Expenses, deductions and exemptions.
• Loans, investments and unexplained credits.
• Capital gains and property transactions.
• TDS, GST and other information mismatches.
• Foreign income, international transactions and related-party matters.

Limited and Detailed Scrutiny

The scope of scrutiny depends on the selection and applicable departmental instructions. In cases involving identified issues, the taxpayer should understand the matters under examination and prepare supporting records accordingly.

A scrutiny notice does not establish that the taxpayer has concealed income or incorrectly claimed deductions.

Professional consideration: A well-supported response at the scrutiny stage is important because the submissions and evidence placed on record can become relevant in future appeal or penalty proceedings.

Read our detailed article on Income Tax Scrutiny Assessment in India.

Best Judgment Assessment — Section 144 / Section 271

Best judgment assessment may arise where the taxpayer fails to comply with specified statutory obligations and the conditions for making such an assessment are satisfied.

Section 144 of the Income-tax Act, 1961 broadly corresponds to section 271 of the Income-tax Act, 2025.

Depending on the governing law, relevant circumstances may include failure to file the required return or failure to comply with applicable assessment notices.

Where the prescribed procedure requires a show cause opportunity, the taxpayer should submit the relevant explanation and supporting evidence within the permitted period.

An assessment completed to the best of judgment does not permit arbitrary determination of income. The assessment must comply with the applicable legal framework.

Faceless Assessment Communications — Section 144B / Section 273

Faceless assessment is an electronic assessment system, not one specific category of notice.

Under the Income-tax Act, 1961, section 144B provides the faceless assessment framework. The corresponding framework under the Income-tax Act, 2025 is contained in section 273.

Notices, questionnaires, show cause communications, hearing-related communications and orders may be issued electronically under the applicable procedure.

Taxpayers should regularly monitor the registered email address and the relevant e-Proceedings section of the Income Tax Portal.

For more information, see our Faceless Income Tax Assessment Procedure and Faceless Assessment FAQs.

Reassessment Show Cause Notice — Section 148A / Section 281

Reassessment proceedings concern income that the Department considers may have escaped assessment.

For relevant earlier periods, section 148A of the Income-tax Act, 1961 governs the applicable pre-notice procedure.

For tax periods governed by the Income-tax Act, 2025, section 281 provides the procedure before issuing a reassessment notice under section 280.

Where section 281 applies, the Department must provide an opportunity of being heard and the relevant information suggesting escaped income, subject to the statutory exceptions.

The taxpayer may be required to explain:

• Whether the transaction belongs to the taxpayer.
• Whether the amount represents taxable income.
• Whether the income has already been disclosed.
• Whether information relied upon by the Department is correct.
• Whether the statutory conditions for reassessment are satisfied.

The statutory exception provisions should be checked before assuming that every reassessment case must follow precisely the same pre-notice process.

Reassessment Notice — Section 148 / Section 280

A formal reassessment notice is issued where the statutory conditions for reassessing income alleged to have escaped assessment are satisfied.

Under the Income-tax Act, 1961, section 148 is the familiar reassessment notice provision. Under the Income-tax Act, 2025, the corresponding provision is section 280.

Reassessment should not be confused with routine scrutiny of a return. It involves separate jurisdictional and procedural requirements.

Limitation Periods for Reassessment Notices

Under the Income-tax Act, 2025, section 282 prescribes limitation periods for notices under sections 280 and 281.

These periods are subject to the complete wording of section 282, including the relevant monetary threshold, exclusions, restrictions and other statutory conditions. Section 282(3) also restricts issuance within one year from the end of a tax year.

Earlier assessment years have their own applicable limitation framework under the Income-tax Act, 1961, including amendments to section 149.

Important: The response deadline mentioned in an individual reassessment notice is different from the statutory limitation period for issuing that notice.

The legal validity of a reassessment proceeding may require examination of jurisdiction, limitation, information relied upon, statutory approvals and the opportunity provided to the taxpayer.

Refer to the official section 280, section 281 and section 282 for the applicable statutory wording.

Rectification Notice — Section 154 / Section 287

Rectification provisions deal with mistakes apparent from the record in specified orders or intimations.

Section 154 of the Income-tax Act, 1961 corresponds to section 287 of the Income-tax Act, 2025.

Examples of matters that may require examination for rectification include apparent calculation errors, incorrect consideration of eligible tax credits or other mistakes apparent from the relevant record.

Rectification is not intended to replace a regular appeal on a debatable factual or legal issue.

Under section 287(4) of the Income-tax Act, 2025, an adverse amendment enhancing an assessment, reducing a refund or otherwise increasing the taxpayer’s liability requires notice and a reasonable opportunity of being heard.

Taxpayers should examine the proposed rectification, reconcile the records and respond through the applicable procedure.

See the official provisions of section 287.

Notice of Demand — Section 156 / Section 289

A notice of demand communicates the amount payable by a taxpayer as determined under the applicable income-tax law.

Under the Income-tax Act, 1961, the familiar notice of demand provision is section 156. The corresponding provision under the Income-tax Act, 2025 is section 289.

Such a notice may involve tax, interest, penalty or another amount payable under the relevant provisions.

The payment period is generally thirty days from service of the notice under the applicable statutory framework, subject to exceptions and lawful variations.

Practical recommendation: Examine the assessment or other underlying order along with the demand notice. Verify the computation, available tax credits, challans and any previously paid amount.

Where the demand is disputed, the taxpayer may need to consider the applicable rectification, appellate and recovery-stay remedies.

For detailed guidance, see Stay of Income Tax Demand After an Assessment Order and Appeal Against an Income Tax Assessment Order.

Penalty Show Cause Notices

Penalty proceedings may arise in connection with alleged defaults under different provisions of the Income-tax Acts.

Unlike some assessment notices, there is no single statutory section covering every type of penalty notice.

A penalty show cause notice may concern matters such as:

• Alleged under-reporting or misreporting of income.
• Failure to comply with specified statutory notices.
• Defaults connected with required statements or reporting obligations.
• Other contraventions for which the applicable Act provides a penalty.

The taxpayer should examine the exact section invoked, the nature of the allegation, the statutory conditions and available explanations or defences.

A penalty should not be assumed to follow automatically merely because an addition has been proposed or an assessment order has been passed. The applicable penalty provisions and procedure must be considered separately.

How Are Income Tax Notices Served and Verified?

Many income-tax communications are issued electronically and can be viewed through the official e-Filing Portal.

Depending on the nature of the communication and applicable procedural rules, the Department may use the registered electronic communication details or other legally permitted modes of service.

How to Authenticate a Notice

1. Visit the official Income Tax e-Filing Portal.
2. Locate the facility for authenticating a notice or order issued by the Department.
3. Use the DIN or other verification particulars as required.
4. Compare the authentication result with the communication received.
5. Review the notice within the appropriate taxpayer account or proceeding.

CBDT instructions regarding the Document Identification Number and permitted exceptions should be examined if a communication is disputed on authentication grounds.

A taxpayer should not assume that a notice is invalid merely because an email was not received or the communication is not immediately visible in one portal section. The mode of service and the applicable legal requirements must be examined.

For electronic response procedures, refer to the Department’s official e-Proceedings guidance.

Practical Example: Identifying Different Income Tax Notices

Consider the following illustrative situations:

These examples are illustrative. The actual notice and statutory provision determine its legal classification.

What Should You Do After Identifying Your Income Tax Notice?

After identifying the notice, the taxpayer should determine whether the communication requires a return correction, document submission, explanation, payment, objection, hearing or other statutory action.

A practical initial checklist is:

• Confirm PAN, taxpayer name and tax period.
• Check the applicable Income-tax Act and section.
• Authenticate the communication where appropriate.
• Identify the deadline stated in the notice.
• Determine the specific action required.
• Collect the relevant financial and tax records.
• Assess whether professional assistance is needed.
• Preserve the notice and subsequent acknowledgements.
