With the ongoing ITR filing and processing cycle for FY26, taxpayers may start receiving intimations under Section 143(1) of the Income Tax Act, 1961. These notices are issued after the Income Tax Department processes a filed return and compares the details with available tax records.
In many cases, the intimation confirms that no further action is required or provides refund details. However, some taxpayers may receive a tax demand if mismatches or discrepancies are identified during processing.
A Section 143(1) intimation is an automated communication issued after the Income Tax Department processes an income tax return. For ITR FY26 filings, the system checks information reported by taxpayers against available tax records, tax credits, and other disclosures.
The outcome may show no changes, a refund, or an additional tax demand. Receiving a tax demand does not automatically indicate that the return was incorrectly filed.
Tax demands during ITR FY26 processing may arise due to mismatches in income details, deductions claimed, or tax credits reported in the return. Differences between the Income Tax Return, Form 26AS, Annual Information Statement (AIS), and Tax Deducted at Source (TDS) records are common reasons for such demands.
In certain cases, computational adjustments made during return processing can also result in additional tax being payable. Taxpayers should carefully review the reason mentioned in the intimation before taking further action.
If you receive an income tax demand notice, follow these steps to respond through the Income Tax e-filing portal:
| Step | What You Need to Do |
| Step 1: Download the Notice | Log in to the Income Tax e-filing portal and view or download the Section 143(1) intimation or the relevant demand notice. |
| Step 2: Verify the Details | Compare the information mentioned in the notice with your filed Income Tax Return (ITR), Form 26AS, Annual Information Statement (AIS), Taxpayer Information Summary (TIS), and other supporting documents. |
| Step 3: Check Whether the Demand Is Correct | Carefully verify whether the tax demand has been calculated correctly based on your tax records and supporting documents. |
| Step 4: If the Demand Is Correct | Pay the outstanding tax amount online through the Income Tax e-filing portal using the available payment options. |
| Step 5: If the Demand Is Partially Correct or Incorrect | Submit an online response on the portal explaining the discrepancy and upload the required supporting documents, if applicable. |
Form 26AS and AIS are important documents for taxpayers filing ITR FY26 as they contain details of income, taxes paid, and tax credits. Any differences between these records and the information reported in the return can lead to adjustments during processing.
Verifying these documents can help identify the source of a mismatch and support an accurate response to the tax authorities. Proper reconciliation of records may also help in resolving the matter more efficiently.
