Defective Return and Updated Return under Income-tax Act 2025

Updated 11 October 2026 · Fact-checked

A return is defective if it does not meet the prescribed conditions. The Assessing Officer intimates the defect and you get 15 days, or a longer period if allowed, to fix it. If you do not, the return is invalid. An updated return can be filed within 48 months from the end of the financial year succeeding the tax year, on payment of additional tax, subject to bars.

Understand Defective Return and Updated Return

Filing a return is not enough. It must also be valid. Section 263(7) says a return is defective if it is not in conformity with the conditions that are prescribed. A missing schedule or a wrongly filled form are typical causes.

If the Assessing Officer (AO) thinks the return is defective, he may intimate the defect to you. You then get an opportunity to rectify it within 15 days from the date of intimation, or within a further period if you apply for it and it is allowed. If you rectify in time, the return stands as a valid return.

If you do not rectify within the allowed period, the return is treated as an invalid return. The Act then applies as if you had failed to furnish the return. This is serious. You may lose the benefit of carrying forward losses and may face penal consequences for non-filing. There is one relief. If you rectify after the period but before assessment is made, the AO may condone the delay and treat the return as valid. This is his discretion, not your right.

An updated return is a different tool. Under section 263(6)(a), any person, whether or not he has filed a return earlier, may furnish an updated return at any time within 48 months from the end of the financial year succeeding the relevant tax year. It lets you report income you missed or never reported. It comes with additional tax payable as the Act provides, so check the rate table in your study material.

An updated return is allowed only to pay more tax, not less. Section 263(6)(c) and (d) list the situations where it is barred. Compare it with the revised return under section 263(5), which corrects an omission or wrong statement in a return already filed, within 12 months from the end of the tax year or before completion of assessment, whichever is earlier.

Key rules to remember

Defective return: rectification period: Rectify within 15 days from the date of intimation (or a further period allowed on application); Section 263(7)(a). The AO intimates the defect first. The clock runs from the intimation.
Consequence of non-rectification: Not rectified in time → invalid return → treated as if no return was furnished; Section 263(7)(b). Rectification after the period but before assessment: AO may condone the delay and treat the return as valid (7)(c).
Time limit for updated return: Within 48 months from the end of the financial year succeeding the relevant tax year; Section 263(6)(a). Available whether or not a return was filed earlier. Additional tax is payable.
Time limit for revised return: Within 12 months from the end of the relevant tax year, or before completion of assessment, whichever is earlier; Section 263(5), as substituted from 1-4-2026. Earlier it was nine months. Do not mix this up with the updated return.
Cases where updated return is barred (main ones): Return of loss (except (6)(b)(i)); decreases tax; creates or increases refund; updated return already filed; assessment proceedings pending or completed (except (6)(b)(ii)); and the other cases in (6)(c); Also barred after search, survey or notice under section 294 as in (6)(d). Learn the list in groups: result of the return, status of the case, information with the department.
Updated return after loss return: Allowed if a loss return was filed by the due date and the updated return is a return of income or reduces the loss; Section 263(6)(b)(i). Also allowed on a notice under section 280, within the period in the notice (6)(b)(ii).

How to solve Defective Return and Updated Return questions

Most questions give a set of facts and ask whether the return is valid, what the deadline is, or whether an updated return can be filed. Work through the same checks each time.

1Identify what is being asked: defective return, revised return or updated return. The facts usually give it away: an AO intimation means defect; an omission found by you means revised or updated.
2For a defective return, note the date of the intimation. Add 15 days, or the extended period if the assessee applied and it was allowed.
3Check whether the defect was rectified within that period. If yes, the return is valid. If no, it is invalid and treated as not furnished.
4If rectified late, check whether assessment has been made. If not, the AO may condone the delay. State that it is his discretion.
5For an updated return, find the end of the financial year succeeding the tax year and add 48 months. Compare with the filing date.
6Run through the bars: loss, lower tax, refund, earlier updated return, proceedings, information with the AO, prosecution, search or survey. One bar is enough to reject.
7Check the effect on carried forward loss or credit. If it falls, updated returns are needed for the later years under section 263(6)(e).
8Conclude with a clear statement: valid or invalid, eligible or not, and the date.

Quickest way: Three-question check

When to use it: Use for short case questions and MCQs where you need an answer in under two minutes.

Who raised it? AO intimation means defective return and the 15-day rule.
Did the assessee fix it on time? No means invalid, as if no return. Late but before assessment means AO may condone.
For updated return: does it raise the tax or income? If it cuts tax, increases refund or is a loss return (outside the (6)(b)(i) exception), reject it. Then check the 48-month limit.

Common mistakes in Defective Return and Updated Return

Saying a defective return is automatically invalid.
Students skip the intimation and rectification stage.
Fix: The return becomes invalid only if the defect is not rectified within the period allowed after the AO's intimation.
Counting the 15 days from the date of filing the return.
The period is assumed to start with the filing.
Fix: The 15 days run from the date of the AO's intimation of the defect.
Saying the AO must accept a late rectification made before assessment.
Students read 'before assessment is made' as a right.
Fix: The law says the AO 'may' condone the delay. It is discretionary.
Mixing the time limits of revised and updated returns.
Both correct a return, so the limits blur together.
Fix: Revised: 12 months from the end of the tax year or before assessment completion, whichever is earlier. Updated: 48 months from the end of the financial year succeeding the tax year.
Allowing an updated return to claim a refund or reduce tax.
Students treat it as a general correction tool.
Fix: It cannot decrease tax liability, or give or increase a refund. It is meant to report more income and pay more tax.
Ignoring the pending proceedings bar.
Students focus on the time limit alone.
Fix: Even within 48 months, an updated return is barred if assessment, reassessment or revision proceedings are pending or completed for that year, except a case under notice under section 280.

Worked examples

Example 1

Anand Textiles filed its return for tax year 2026-27. On 10 January 2028 the AO intimated a defect. Anand did not apply for any extension. (a) By what date must it rectify? (b) It rectified on 5 February 2028 and no assessment has been made. What is the position?

Show the solution

The rectification period is 15 days from the date of intimation, 10 January 2028.
10 January 2028 + 15 days = 25 January 2028.
Anand rectified on 5 February 2028, after 25 January 2028. So the rectification is late.
Because the defect was not rectified within the period, the return is an invalid return and the Act applies as if no return was furnished.
However, rectification was made before the assessment. The AO may condone the delay and treat the return as valid. This is his discretion.

Answer: (a) 25 January 2028. (b) The return is invalid unless the AO condones the delay; since assessment is not yet made, he may do so and treat it as valid.

Example 2

Meera Rao filed a return for tax year 2026-27 showing tax of ₹40,000. In December 2029 she finds that she missed some income. No proceeding is pending for that year and no updated return has been filed. (a) Can she file an updated return, and what is the last date? (b) Could she instead file an updated return to claim an extra refund of ₹5,000 she forgot to claim?

Show the solution

The relevant tax year is 2026-27. The financial year succeeding it is 2027-28, which ends on 31 March 2028.
Add 48 months to 31 March 2028. The last date is 31 March 2032.
December 2029 is before 31 March 2032, so the time limit is met.
Check the bars. The return reports more income, so it does not decrease tax liability. No proceeding is pending and no updated return was filed earlier. So she is eligible, and additional tax is payable as the Act provides.
For (b), an updated return that results in a refund where none was due, or increases the refund due on the earlier return, is barred under section 263(6)(c)(iii).

Answer: (a) Yes. She can file an updated return up to 31 March 2032, paying the additional tax. (b) No. An updated return cannot be used to claim or increase a refund.

Exam tips

Write the section number 263(7) for defective return and 263(6) for updated return. They are a clean way to score the 'provision' mark.
Always compute the dates. In date-based questions, show the addition (15 days or 48 months) as a line of working.
Remember that under 263(7)(c), condonation is by the AO and optional. Use 'may'.
For updated return questions, list each bar that applies and say which one blocks the filing. A one-line conclusion without the reason loses marks.
In MCQs, watch the distractors: nine months for revised return is the old limit; the current limit is 12 months.

Defective Return and Updated Return: frequently asked questions

What is the rectification period for a defective return under the Income-tax Act, 2025?

It is 15 days from the date of the AO's intimation of the defect. The AO may allow a further period if you make an application. This is in section 263(7)(a).

When is a return treated as invalid?

A return is invalid when it is defective and the defect is not rectified within the period allowed. The Act then applies as if you had not furnished a return. If you rectify late but before assessment, the AO may condone the delay.

What is the difference between a revised return and an updated return?

A revised return corrects an omission or wrong statement in a return already filed, within 12 months from the end of the tax year or before assessment completion, whichever is earlier. An updated return can be filed whether or not you filed earlier, within 48 months from the end of the financial year succeeding the tax year, with additional tax. It cannot reduce tax or increase a refund.

Can I file an updated return if my case is under assessment?

Generally no. It is barred if assessment, reassessment, recomputation or revision proceedings are pending or completed for that year. The exception is an updated return filed on a notice under section 280, within the period stated in the notice.
