“You Have a Demand for AY 2026–27”: What to Check Before You Pay

Where the demand has arisen after CPC processed your return, start with the section 143(1) intimation. Check whether TDS, TCS, advance tax and self-assessment tax have been recognised correctly and whether CPC made any adjustment to the figures reported in your return.

This check is important because the portal provides different responses for a demand that is correct, already paid or disputed. Once you submit “Demand is Correct”, the Income Tax Department states that you cannot later select “Disagree with Demand” for that demand through the same response facility.

For income earned during FY 2025–26, the relevant return is for AY 2026–27 and continues to be governed by the Income-tax Act, 1961 under the transition provisions.

1. What does an AY 2026–27 demand mean?#

An outstanding demand can arise from CPC or an Assessing Officer. This article focuses on the common situation where CPC has processed an AY 2026–27 return and the resulting section 143(1) intimation shows an amount payable.

Where an amount is determined as payable under section 143(1), that intimation is treated as a notice of demand for the purposes of section 156.

A demand does not necessarily mean that you failed to pay tax. It could arise because:

• a self-assessment or advance-tax payment was not given credit;
• TDS or TCS claimed in the return does not match the Department's records;
• CPC made an adjustment while processing the return; or
• the tax or interest calculated after processing differs from your return.

The first step is therefore to identify the difference rather than immediately paying the amount shown.

2. Start with the section 143(1) intimation and tax credits#

Log in to the e-Filing portal and go to:

e-File → Income Tax Returns → View Filed Returns

Download the filed return and the section 143(1) intimation. Compare the figures reported by you with the figures processed by CPC, particularly total income, deductions, TDS/TCS, advance tax, self-assessment tax, interest and the final demand or refund.

The portal also provides a Tax Credit Mismatch service. It compares tax credits claimed in the return with the credits available in Form 26AS.

If self-assessment or advance tax is missing or incorrect, check the challan details and PAN.

If the problem relates to TDS and the TDS itself is not correctly reflected in Form 26AS, the Income Tax Department advises the taxpayer to approach the employer or other deductor so that the TDS statement can be corrected. A taxpayer should not simply use rectification to claim TDS that is not available in the Department's tax-credit records.

3. Which response should you choose?#

To respond to the demand, log in and go to:

Pending Actions → Response to Outstanding Demand

The portal broadly provides the following choices:

Be particularly careful before selecting Demand is Correct. The portal's user manual states that once this response is submitted, you cannot later select “Disagree with Demand” for the same demand through this facility.

If the demand is genuinely payable, also check the payment date. Under section 220, an amount specified in a notice of demand is normally payable within 30 days of service, subject to statutory exceptions. Delay beyond the permitted period can attract simple interest at 1% for every month or part of a month until payment.

4. When should you use rectification instead?#

If the demand has arisen because of a mistake apparent from the record in a CPC intimation, rectification may be more appropriate than paying the amount again.

For a return processed by CPC, the portal path is:

Login → Services → Rectification → New Request → Income Tax → select the relevant Assessment Year

The portal provides different rectification request types. The three most relevant for an individual taxpayer are:

Reprocess the Return

Use this where the information in your original or revised return was already true and correct, but CPC did not consider it correctly during processing.

For example, you correctly claimed a tax credit or deduction in the filed return, but it was not taken into account while processing.

You are essentially asking CPC to process the existing return again. You are not changing the return data.

Tax Credit Mismatch Correction

Use this where the issue relates to the tax-credit schedules in the processed return, such as:

TDS, TCS, advance tax or self-assessment tax.

For example, the self-assessment-tax challan was valid but you entered an incorrect BSR code, challan number, payment date or amount in the return.

The portal allows the relevant tax-credit schedules to be corrected.

However, if TDS itself is missing from Form 26AS, the deductor may first need to correct the TDS statement.

Return Data Correction

This applies where some of the return data itself was entered incorrectly and the mistake is capable of rectification from the existing record.

For example, the Income Tax Department specifically gives the case of income being shown under an incorrect head of income.

Return Data Correction can currently be available through online or offline rectification options depending on the case. In the online flow, the taxpayer selects the relevant rectification reasons and schedules and corrects the required details.

It is important to understand its limits. Return Data Correction is not intended to introduce a new source of income or make a fresh or additional deduction. The Department also restricts fresh or additional claims or reductions relating to matters such as brought-forward losses, carry-forward losses, MAT credit and Chapter VI-A deductions through this rectification route.

A simple way to remember the difference is:

• Return was correct but CPC processing was wrong → Reprocess the Return
• Tax-credit details need correction → Tax Credit Mismatch Correction
• Data entered in the return itself needs an eligible correction → Return Data Correction

Rectification should not be treated as a substitute for a revised return where the mistake is one that legally requires the return itself to be revised.

5. What if the challan itself contains the mistake?#

There is an important difference between entering a correct challan incorrectly in the ITR and the original challan itself containing the wrong particulars.

For certain challan errors, the e-Filing portal provides:

Login → Services → Challan Correction

The online facility currently permits specified corrections relating to Assessment Year/Tax Year, Major Head and Minor Head for eligible challans.

However, the facility has conditions. The challan generally needs to be open or unconsumed, and the online facility currently covers relevant challans for AY 2020–21 onwards.

The current portal time limits are:

• Assessment Year/Tax Year: within 7 days of the challan deposit date.
• Major Head or Minor Head: within 30 days of the challan deposit date.

For online Minor Head correction, the portal currently covers Minor Heads 100 (Advance Tax), 300 (Self-Assessment Tax) and 400 (Demand Payment as Regular Assessment Tax).

Where online correction is unavailable or the applicable time limit has expired, the taxpayer may need to approach the Jurisdictional Assessing Officer, depending on the circumstances.

Therefore, someone who notices a challan error only after the return has been processed should not assume that online challan correction will still be available.

6. Example: tax was paid but CPC still shows a demand#

Suppose Arun files his AY 2026–27 return after paying ₹38,000 as self-assessment tax.

The payment is valid and appears in Form 26AS, but Arun entered one of the challan particulars incorrectly in his return. CPC processes the return without giving the expected credit and a demand appears.

Arun should not immediately pay another ₹38,000.

He should compare Form 26AS and the original challan with the self-assessment-tax details entered in his filed return.

If the payment exists correctly in the Department's records but the challan particulars were entered wrongly in the ITR, Tax Credit Mismatch Correction may be the appropriate rectification route.

If the error is in the challan itself, the separate Challan Correction facility and its eligibility conditions and time limits need to be checked.

The important point is to establish where the error occurred before deciding how to respond.

7. What should you check before responding?#

Before responding to an AY 2026–27 demand:

• Download the filed return and section 143(1) intimation.
• Compare the returned figures with the processed figures.
• Check Form 26AS and the Tax Credit Mismatch service.
• Reconcile advance-tax and self-assessment-tax challans.
• Check whether missing TDS requires correction by the deductor.
• Identify whether the problem lies in CPC processing, the tax-credit schedules, the return data or the underlying challan.
• Only then choose Demand is Correct, Already Paid, Disagree with Demand, rectification or challan correction, as applicable.

Ignoring the demand does not make it disappear. The Income Tax portal states that an unanswered demand may remain payable and may be adjusted against a refund. Section 245 provides for adjustment of a refund against an amount remaining payable after the prescribed intimation of the proposed adjustment.

Key takeaway: Seeing “You have a demand for AY 2026–27” does not automatically mean you should pay immediately. First establish why the demand arose. If it is genuinely payable, respond and pay it within the applicable period. If tax has already been paid or a clear CPC, tax-credit, return-data or challan error exists, use the correction route that matches the actual problem rather than paying the same tax again.
