Plain-language answers, reviewed for publication.
Each question has a shareable anchor, a verdict-first answer, and links into the calculators, calendar, glossary or sibling guide pages where relevant.
1Is a 143(1) intimation a notice — should I panic?
No — a 143(1) intimation is usually a processing summary, not a reason to panic. Compare the income, deductions, TDS and tax payable/refund shown in the intimation with your filed return. If it matches, keep it on record. If it creates a demand or reduces a refund, check the mismatch reason before paying or responding.
2I got a demand in 143(1) but disagree — what now?
Do not ignore it, but do not pay blindly either. First reconcile the demand with the return, Form 26AS/AIS and the intimation. If the department's processing is wrong, the usual routes are an online response, rectification request or appeal, depending on the issue and deadline.
3Why is my refund adjusted against an old demand?
Do not ignore it, but do not pay blindly either. First reconcile the demand with the return, Form 26AS/AIS and the intimation. If the department's processing is wrong, the usual routes are an online response, rectification request or appeal, depending on the issue and deadline.
B · Defective returns
4What does defective return under 139(9) mean?
A defective-return notice means the return is incomplete or inconsistent and must be corrected on the portal. Common triggers include missing schedules, inconsistent income figures, audit-report issues or wrong ITR form. The response window is time-bound, so download the notice, identify the defect code and upload the corrected response before the deadline.
5How many days do I have to fix a defective return?
A defective-return notice means the return is incomplete or inconsistent and must be corrected on the portal. Common triggers include missing schedules, inconsistent income figures, audit-report issues or wrong ITR form. The response window is time-bound, so download the notice, identify the defect code and upload the corrected response before the deadline.
6What if I miss the defective-return response deadline?
A defective-return notice means the return is incomplete or inconsistent and must be corrected on the portal. Common triggers include missing schedules, inconsistent income figures, audit-report issues or wrong ITR form. The response window is time-bound, so download the notice, identify the defect code and upload the corrected response before the deadline.
C · AIS, e-campaign and high-value alerts
7Why did I get an SMS about a high-value transaction?
Treat AIS/e-campaign alerts as mismatch checks, not automatic tax demands. If the information belongs to you, reconcile it with the return. If it is wrong or duplicated, give AIS feedback and keep evidence. Ignoring a genuine mismatch can lead to further questions later.
8AIS shows income that is not mine — how do I dispute it?
Treat AIS/e-campaign alerts as mismatch checks, not automatic tax demands. If the information belongs to you, reconcile it with the return. If it is wrong or duplicated, give AIS feedback and keep evidence. Ignoring a genuine mismatch can lead to further questions later.
9Can I ignore an e-campaign message if my return is correct?
Treat AIS/e-campaign alerts as mismatch checks, not automatic tax demands. If the information belongs to you, reconcile it with the return. If it is wrong or duplicated, give AIS feedback and keep evidence. Ignoring a genuine mismatch can lead to further questions later.
D · 142(1), 148 and reopening
10What is the difference between 142(1) and 148?
142(1) is an enquiry/information notice; 148 is a reassessment/reopening notice. The response strategy is different: 142(1) usually asks for a return, documents or explanations, while 148 can reopen an assessment year subject to statutory safeguards and time limits under the applicable Act.
11Notice for a year I did not file — what happens?
Respond through the income-tax portal and keep a complete trail. Most notices/intimations are visible under e-Proceedings or related portal tabs, even if an email or SMS alerted you first. Save the notice PDF, acknowledgement, submitted documents and any follow-up order.
12How long after filing can the department reopen my return?
142(1) is an enquiry/information notice; 148 is a reassessment/reopening notice. The response strategy is different: 142(1) usually asks for a return, documents or explanations, while 148 can reopen an assessment year subject to statutory safeguards and time limits under the applicable Act.
E · Portal procedure
13Do notices come by post or only on the portal?
Respond through the income-tax portal and keep a complete trail. Most notices/intimations are visible under e-Proceedings or related portal tabs, even if an email or SMS alerted you first. Save the notice PDF, acknowledgement, submitted documents and any follow-up order.
14Where do I upload a response on the income-tax portal?
Respond through the income-tax portal and keep a complete trail. Most notices/intimations are visible under e-Proceedings or related portal tabs, even if an email or SMS alerted you first. Save the notice PDF, acknowledgement, submitted documents and any follow-up order.
15When is it worth getting professional help?
Respond through the income-tax portal and keep a complete trail. Most notices/intimations are visible under e-Proceedings or related portal tabs, even if an email or SMS alerted you first. Save the notice PDF, acknowledgement, submitted documents and any follow-up order.
