What Is an Intimation Under Section 143(1)?

After filing your Income Tax Return (ITR), you might receive a document called an intimation under Section 143(1) from the Income Tax Department. This isn’t a notice of scrutiny or audit—it’s simply a communication that reflects how your return was processed. Think of it as a summary report showing whether your return was accepted as-is or adjusted based on certain checks.

Why Does the Department Send This Intimation?

Once you file your ITR, the system cross-verifies the details you submitted. The purpose is to catch basic mistakes or inconsistencies—not to question your intent, but to ensure everything adds up correctly.

Here are a few things the CPC checks:

Errors in arithmetic or calculations
Mismatches in income details (especially from Form 26AS or AIS)
TDS discrepancies
Invalid or excess deductions and exemptions
PAN or Aadhaar inconsistencies
Incorrect advance tax or self-assessment tax figures

What Can the Outcome Be?

Your Section 143(1) intimation will show one of three possibilities:

No demand, no refund – The department agrees with your return as filed. Nothing more needs to be done.
Refund due – You’ve paid more tax than necessary. A refund is initiated.
Tax payable (demand) – There’s a shortfall in the tax paid due to a mismatch or error.

How Will You Receive the Intimation?

The intimation is shared through multiple channels:

Sent to your registered email ID
Available in your income tax e-filing account
You may also get an SMS alert notifying you that it’s been issued

The file is usually a password-protected PDF. To open it, use your lowercase PAN number followed by your date of birth in DDMMYYYY format.

When Can You Expect to Receive It?

The Income Tax Department has a set timeframe for this. They must issue the intimation within 9 months from the end of the financial year in which your return was filed.

For example: If you filed your return for FY 2023–24 in July 2024, the intimation can be sent anytime up to 31 December 2025. If you don’t receive it within that time, your return is deemed accepted.

What Should You Do After Receiving It?

Here’s a step-by-step guide to handling the intimation:

1. Go through it carefully

Check key details like:

PAN and assessment year
Calculated income and deductions
Tax payable or refund amount

Compare the department’s numbers with what you filed.

2. If there’s a tax demand

If the difference is valid, pay it right away to avoid penalties.
If you believe there’s a mistake, you can take one of the following actions:
- File a rectification request under Section 154
- Revise your return, if still within time
- File an appeal under Section 246A (if applicable)

3. If there’s a refund

You don’t need to do anything—just keep an eye on your bank account for the credit.

4. If everything matches

No action is needed. Your return has been successfully processed.

How to File a Rectification Request (Section 154)

If you spot an error in the intimation, here's how you can file a rectification:

Log in to the Income Tax Portal
Go to Services > Rectification
Select the relevant assessment year
Specify the issue and upload supporting documents, if needed
Submit and e-verify

Pro Tips & Precautions

Always cross-check details in the intimation—don’t skip over the numbers.
Pay any tax demand within the due date to avoid interest or penalty.
If there's an error, act quickly. Timelines for rectification and appeals are strict.
Keep a copy of the intimation PDF for your records.

Final Thoughts

Getting an intimation under Section 143(1) is a standard part of the ITR process. It simply means your return has gone through initial automated checks. Unless you spot a discrepancy or are asked to pay more tax, you likely don’t need to worry.
