Intimation Under Section 143(1) of Income Tax Act Explained

Did you know 9.19 crore people filed tax returns for the Assessment Year 2025-26? The tax office will issue an equal number of intimation notices after verifying every return to ensure that your return has been processed. This issuance is part of Intimation under Section 143(1) of the Income Tax Act.

The Intimation under Section 143(1) provides a summary of the information submitted by the taxpayer and the details considered by the Income Tax Department while processing the return. The Intimation under Section 143(1) generally includes the following information:

• Tax calculations as declared in the filed Income Tax Return
• Refund sequence number, if applicable
• Taxpayer details such as name, PAN, and address
• Tax computed by the Income Tax Department under Section 143(1)
• Income tax return details, including the date of filing and acknowledgement number

So, if you have recently received a notice from the Income Tax Department, then no need to panic. These notices are just a routine confirmation. All you need to know is Section 143(1) of the Income Tax Act to handle the legal notices in the right way.

What is Section 143(1) of the Income Tax Act?

What to Check Before Replying to a Section 143(1) Intimation?

After accessing your intimation using your ITR password, examine it carefully. The notice under Section 143(1) of the Income Tax Act will indicate if any action is required.

 If the department has raised a demand, you should:

• Verify their calculations thoroughly.
• Identify any differences between your records and their assessment.
• Check if they’ve adjusted your refund against previous liabilities.
• Ensure all income sources reported match with Form 26AS.
• Verify TDS Return credits have been properly reflected.
• Check for arithmetic errors in tax calculation.
• Review if any eligible deductions were missed or disallowed.
• Note the time limit (30 days) to respond if you disagree with the assessment.
• Submit your response with supporting documents if contesting the notice.

The tax department may adjust your refund if you have outstanding tax liabilities from previous assessment years.

What Happens If You Don’t Respond to Section 143(1) Intimation Within Time?

If you fail to respond to a Section 143(1) Income Tax Act notice within the 30-day timeframe:

• The tax department will consider the demand as valid and confirmed.
• You’ll be liable to pay the full demanded amount plus applicable interest.
• The department may initiate recovery proceedings to collect the outstanding tax.
• Your future refunds might get automatically adjusted against this demand.
• It could potentially trigger closer scrutiny of your returns in upcoming years. 

Remember, ignoring a tax notice never makes it go away; it only complicates your tax situation further.

How to File a Response to Section 143(1) Income Tax Intimation?

To submit a response to the intimation notice:

1. Log in to the Income Tax portal
2. Go to “e-File” and select “Response to Outstanding Demand“.
