Excess Refund Received After Demerger: When the Original Return is Processed After Filing of Modified Return under Section 170A
Summary: Section 170A of the Income-tax Act, 1961 provides a statutory mechanism for filing modified returns following business reorganisations such as demergers and amalgamations. The provision applies where a return was filed before the order approving the reorganisation and requires the successor to furnish a modified return within the prescribed period. Section 170A(2)(a) applies where assessment or reassessment has already been completed when the modified return is furnished, while Section 170A(2)(b) applies where proceedings are pending and requires the Assessing Officer to take the modified return into account. The supplied material discusses an illustration where a company claimed a Rs. 2 crore refund in its original return, reduced it to Rs. 1 crore through a Section 170A modified return filed before processing, but subsequently received Rs. 1.50 crore under Section 143(1). It states that the company should reconcile the refund and may consider rectification under Section 154, depending on whether the issue constitutes a mistake apparent from the record. Any excess refund may be recoverable, with Section 234D potentially relevant to interest. The material discusses judicial decisions including Technoforce Solutions, Bajaj Electricals, CIT v. Indian Oil Corporation Ltd., and DLF Home Developers Ltd. v. National Faceless Assessment Centre.
Introduction
Business reorganisations, particularly demergers and amalgamations, often have tax consequences that relate back to an appointed date which may be considerably earlier than the date on which the scheme is sanctioned by the National Company Law Tribunal (“NCLT”).
This creates a peculiar compliance situation under the Income-tax Act, 1961 (“the Act”). A company may have already filed its return of income for a particular assessment year before the demerger is sanctioned. Subsequently, once the scheme becomes effective, the successor entity is required to give effect to the reorganisation through a modified return under Section 170A of the Act.
A practical difficulty arises where the original return is processed under Section 143(1) after the modified return has already been filed.
Consider a simple illustration.
A company files its original return of income for AY 2025-26 declaring a refund of ₹2 crore. Subsequently, pursuant to a demerger having retrospective effect from an earlier appointed date, the company files a modified return under Section 170A reducing the refund claim to ₹1 crore.
Importantly, the modified return is filed before the original return is processed.
Despite this, the original return is subsequently processed under Section 143(1), and the company receives a refund of ₹1.50 crore.
The company has therefore received ₹50 lakh more than the refund claimed in the modified return.
This raises several questions.
– Can the company retain the additional ₹50 lakh?
– Does the subsequent processing of the original return override the modified return?
– What is the remedy available to the assessee?
– Can the Department recover the excess refund?
– Would interest under Section 234D apply?
– Can the company itself approach the Department for rectification?
The answers require a combined reading of Sections 143(1), 154, 170A and 234D, along with the judicial precedents which have recently emerged on Section 170A.
Section 170A – The statutory mechanism for business reorganisation
Section 170A was inserted by the Finance Act, 2022 with effect from 1 April 2022 to address the difficulties arising where a business reorganisation takes place after the return of income has already been furnished.
The provision applies to a “business reorganisation”, which includes amalgamation, demerger or merger of businesses.
Where, prior to the date of the order approving the business reorganisation, a return of income has already been furnished for an assessment year to which the order applies, the successor is required to furnish a modified return within six months from the end of the month in which the order is issued.
The modified return is required to be in the prescribed form and manner and is required to be in accordance with, and limited to, the order approving the business reorganisation.
The importance of Section 170A lies in the fact that it is not merely another mechanism for voluntarily revising an income-tax return.
It is a special statutory mechanism designed to ensure that the income-tax position reflects the consequences of a legally sanctioned business reorganisation.
The distinction between Section 170A(2)(a) and Section 170A(2)(b)
Section 170A(2) is particularly important in the present context.
Where assessment or reassessment proceedings have already been completed on the date on which the modified return is furnished, Section 170A(2)(a) requires the Assessing Officer to pass an order modifying the total income determined in the completed assessment or reassessment.
On the other hand, where assessment or reassessment proceedings are pending on the date of furnishing the modified return, Section 170A(2)(b) requires the Assessing Officer to assess or reassess the total income in accordance with the order of business reorganisation and take into account the modified return.
Therefore, the exact date on which the modified return is filed assumes considerable significance.
This distinction has now received judicial consideration.
Technoforce Solutions: Section 170A cannot be ignored after filing of modified return
A particularly relevant judgment is the recent decision of the Bombay High Court in Technoforce Solutions (I) Private Limited v. Deputy Commissioner of Income Tax, decided on 1 April 2026.
In that case, the assessee had originally filed its return for AY 2023-24. The return was processed under Section 143(1).
Subsequently, an amalgamation order was passed by the NCLT and the assessee filed a modified return under Section 170A.
The Department subsequently issued notices under Sections 143(2) and 142(1).
The Bombay High Court examined the scheme of Section 170A and noted the distinction between a case where assessment has already been completed and one where assessment proceedings are pending when the modified return is filed.
The Court recorded that where the assessment had already been completed when the modified return was furnished, Section 170A(2)(a) required the Assessing Officer to modify the total income determined under the earlier assessment in accordance with the business reorganisation order and after taking into account the modified return.
The judgment is particularly significant because the Court recognised the statutory mechanism under Section 170A as a specific framework for giving effect to the business reorganisation rather than permitting the Department to simply disregard the modified return.
The decision is important for the present issue because it demonstrates that a Section 143(1) intimation does not necessarily represent the end of the matter where a subsequent statutory modification under Section 170A is required to give effect to a business reorganisation.
Bajaj Electricals: Modified return must be taken into account
Another important decision is Bajaj Electricals Limited v. Assistant Commissioner of Income Tax, Bombay High Court, decided on 9 February 2026.
The case involved, among other things, a demerger and a subsequent amalgamation.
The assessee had filed a modified return under Section 170A pursuant to the business reorganisation.
The Bombay High Court examined the statutory scheme and observed that where assessment proceedings were pending on the date on which the modified return was furnished, the Assessing Officer was required to assess the total income in accordance with the business reorganisation order while taking into account the modified return.
The Court also dealt with the situation where the assessment order itself contained a computation based on the earlier return rather than the modified return.
Importantly, the assessee had filed a rectification application seeking correction of the mistake in the assessment order.
The decision therefore provides useful support for the proposition that where the assessment or processing does not correctly incorporate the modified return, the assessee can seek appropriate correction rather than treating the earlier computation as sacrosanct.
Applying the judicial principles to the present fact pattern
In the present illustration, the chronology is critical.
The company first filed its original return claiming a refund of ₹2 crore.
The demerger was subsequently sanctioned and the company filed a modified return under Section 170A claiming a refund of ₹1 crore.
The modified return was filed before the original return was processed under Section 143(1).
The original return was nevertheless processed and a refund of ₹1.50 crore was granted.
At first glance, one may argue that the assessment was “pending” when the modified return was filed because the original return had not yet been processed.
This would potentially bring the case within Section 170A(2)(b).
Under that provision, the Assessing Officer is required to assess or reassess the total income in accordance with the business reorganisation order while taking into account the modified return.
This is materially different from a situation where the original return had already been processed before the modified return was furnished.
Accordingly, on the assumed facts, the company has a strong statutory basis for contending that the modified return should be given effect to notwithstanding the subsequent processing of the original return.
Does receipt of ₹1.50 crore make the entire refund final?
Not necessarily.
A Section 143(1) intimation is an assessment-related determination of the return under the statutory processing mechanism. However, the Act itself contains mechanisms through which the tax position can subsequently be modified.
In the present case, the existence of the Section 170A modified return is crucial.
The Department cannot determine the final tax consequence of the demerger merely by looking at the original return while disregarding the statutory modified return.
Therefore, the company should not assume that the ₹1.50 crore credited to its bank account represents the final legally allowable refund.
The appropriate question is:
What is the refund legally payable after giving effect to the demerger and the Section 170A modified return?
If the answer is ₹1 crore, then the additional ₹50 lakh represents an excess refund which would have to be appropriately adjusted or recovered.
Section 154 – An important remedy
Section 154 provides a mechanism for rectification of mistakes apparent from the record.
The provision specifically enables rectification of an intimation issued under Section 143(1).
This becomes relevant where the tax processing does not correctly reflect information already available on the record.
In the present situation, the company may consider filing a rectification application explaining that:
– the original return was filed claiming a refund of ₹2 crore;
– a demerger subsequently took place pursuant to an order of the competent authority;
– a modified return under Section 170A was duly filed;
– the modified return claimed a refund of ₹1 crore;
– the modified return was filed before processing of the original return;
– the original return was subsequently processed under Section 143(1); and
– the processing resulted in a refund of ₹1.50 crore.
The company can request that the refund determination be corrected after taking into account the modified return filed under Section 170A.
The Bombay High Court’s decision in Bajaj Electricals is useful in this context because the assessee itself had resorted to rectification where the computation in the assessment order did not properly reflect the modified return.
However, one should not mechanically assume that every Section 170A issue is necessarily a “mistake apparent from the record”. If determination of the issue requires a detailed investigation, interpretation of the scheme or resolution of a debatable question, the availability of Section 154 may need to be examined separately.
Can the Department recover the ₹50 lakh?
If, after giving effect to the demerger and the modified return, the final refund is ₹1 crore, the Department would ordinarily be entitled to recover or adjust the excess refund of ₹50 lakh.
The mere fact that the amount was credited through the automated processing of the original return does not confer a substantive right upon the assessee to retain an amount which is ultimately found not refundable.
The more appropriate way of looking at the situation is that the original processing resulted in a refund which was subsequently required to be recomputed because of the business reorganisation.
The company should therefore not treat the additional ₹50 lakh as distributable surplus or ordinary business funds.
Interest under Section 234D
The next question is whether interest would also be payable on the excess refund.
Section 234D deals specifically with interest on excess refunds.
Where a refund is granted under Section 143(1) and subsequently, on regular assessment, it is found that the refund or a portion thereof was excessive, Section 234D provides for interest on the excess amount subject to the conditions prescribed in the provision.
The rate is 0.5% for every month or part of a month for the prescribed period.
The provision therefore creates a separate exposure over and above the principal amount of excess refund.
The Bombay High Court’s decision in CIT v. Indian Oil Corporation Ltd. is an important authority on Section 234D. The judgment considered the scope and operation of Section 234D and the effect of Explanation 2 inserted by the Finance Act, 2012.
Subsequent decisions have followed the principle that Section 234D applies where the statutory conditions relating to an excess refund granted under Section 143(1) are satisfied.
However, in the present fact pattern, the computation of interest should be undertaken only after determining the final amount of refund legally due following the Section 170A proceedings.
It would therefore be premature to simply calculate interest on ₹50 lakh from the date of the refund without examining the precise statutory mechanism through which the excess refund is ultimately determined.
Is there a penalty merely because excess refund was received?
The receipt of an excess refund does not, by itself, establish that the assessee has furnished inaccurate particulars or deliberately misrepresented facts.
This distinction is important.
If the company:
– correctly disclosed the demerger;
– filed the original return based on the facts existing at that time;
– subsequently filed the statutory modified return under Section 170A;
– reduced its refund claim from ₹2 crore to ₹1 crore; and
– received ₹1.50 crore only because the original return was processed separately,
the facts indicate a processing mismatch rather than an intentional attempt to obtain an excessive refund.
The company should nevertheless act promptly once the discrepancy comes to its knowledge.
A contemporaneous disclosure to the Department, coupled with an application seeking correction, would substantially strengthen the company’s position that the excess refund was not knowingly or fraudulently retained.
Does the company need to immediately deposit ₹50 lakh?
This requires a distinction between identifying an excess refund and determining the final statutory liability.
The company should first reconcile the refund.
This reconciliation should include the tax paid, TDS/TCS credits, advance tax, self-assessment tax, refund determined under Section 143(1), interest under Section 244A and the refund ultimately claimed under the Section 170A modified return.
Only after this reconciliation should the company determine the precise excess amount.
If the final position is unquestionably that ₹50 lakh is not refundable, the company should make appropriate arrangements for the liability rather than utilising the amount.
At the same time, where the Department has not yet issued a demand and the appropriate statutory mechanism for giving effect to Section 170A is still available, a premature payment without establishing the correct computation may create unnecessary reconciliation complications.
The better approach is to proactively approach the Department and seek appropriate correction.
The importance of the appointed date and effective date
Demerger cases require particular caution because the scheme may operate from an appointed date that precedes the date of the NCLT order.
For example, a scheme may be sanctioned in FY 2025-26 but operate from an appointed date falling in FY 2024-25.
This creates the possibility that the original return for AY 2025-26 was correctly filed before the scheme was sanctioned but subsequently requires modification after the scheme becomes effective.
That is precisely the type of situation for which Section 170A was introduced.
The modified return should therefore be examined against the actual NCLT order and not merely against the accounting entries passed by the company.
The distinction between a modified return and a revised return
Another important point is that a Section 170A modified return should not be casually equated with an ordinary revised return under Section 139(5).
A revised return under Section 139(5) is generally intended to correct an omission or wrong statement in an earlier return.
A Section 170A return, on the other hand, is triggered by a legally sanctioned business reorganisation.
Its purpose is to align the tax computation with the consequences of that reorganisation.
The Bombay High Court’s recent decisions in Bajaj Electricals and Technoforce Solutions reinforce the importance of giving effect to this special statutory mechanism.
Other judicial developments on Section 170A
The judicial landscape surrounding Section 170A is still developing because the provision was introduced only with effect from 1 April 2022.
The Bombay High Court’s decisions are therefore particularly significant.
In Bajaj Electricals Limited, the Court considered the interaction between the modified return and pending assessment proceedings and emphasised that the assessment had to be undertaken in accordance with the business reorganisation order and after taking the modified return into account.
In Technoforce Solutions, the Bombay High Court considered a situation where the assessment had already been completed under Section 143(1) when the modified return was subsequently filed. The Court recognised that Section 170A(2)(a) requires modification of the earlier determination rather than ignoring the statutory modified return.
The Madras High Court has also considered Section 170A in cases involving business reorganisation and has discussed the significance of the provision in the context of returns filed following amalgamation.
The Delhi High Court has also been approached in matters involving Section 170A, including the practical difficulties faced by taxpayers following business reorganisations. DLF Home Developers Ltd. v. National Faceless Assessment Centre is one such matter where the Court called upon the Revenue to address the difficulties arising from interpretation and implementation of Section 170A.
These decisions collectively indicate that Section 170A is not merely a procedural filing provision. It creates a statutory mechanism through which the tax computation is required to be aligned with the approved business reorganisation.
What should the company do in the present case?
In the given example, the company should undertake the following course of action.
First, obtain and preserve the Section 143(1) intimation pursuant to which ₹1.50 crore was refunded.
Second, preserve the acknowledgement and complete computation of the Section 170A modified return under which the refund was reduced to ₹1 crore.
Third, establish the exact date on which the modified return was filed.
Fourth, establish the exact date on which the original return was processed.
Fifth, verify the date of the NCLT or other competent authority order and the appointed date of the demerger.
Sixth, prepare a reconciliation explaining why the refund reduced from ₹2 crore to ₹1 crore after giving effect to the demerger.
Seventh, approach the Assessing Officer/CPC through the appropriate statutory mechanism and place the entire chronology on record.
Eighth, consider filing a rectification application under Section 154 wherever the error is capable of being characterised as a mistake apparent from the record.
Ninth, request that the tax computation and refund be recomputed after giving effect to Section 170A.
Tenth, once the final amount is determined, pay or adjust the excess refund together with applicable statutory interest, if any.
A possible representation to the Department
The company’s representation should not merely say that an “excess refund has been received.”
It should specifically state that the original return was followed by a statutory modified return under Section 170A and that the original return was subsequently processed without giving effect to the modified return.
The company should request that the Department:
«”kindly give effect to the modified return furnished under Section 170A pursuant to the order approving the business reorganisation and recompute the total income and consequential refund for AY 2025-26. The refund granted pursuant to processing of the original return under Section 143(1) may kindly be reconciled with the refund legally admissible after giving effect to the modified return, and appropriate consequential adjustment may be carried out in accordance with law.”»
This wording is preferable to simply admitting that the company has “wrongly received ₹50 lakh”, because the legal issue is actually one of giving effect to the statutory modified return and consequential recomputation of the refund.
Conclusion
The situation where an assessee receives a higher refund pursuant to processing of its original return after filing a Section 170A modified return presents a classic example of the challenges created by retrospective business reorganisations.
In the illustration considered above, the original return claimed a refund of ₹2 crore, whereas the modified return filed pursuant to the demerger claimed only ₹1 crore. Nevertheless, processing of the original return resulted in a refund of ₹1.50 crore.
The additional ₹50 lakh should not simply be treated as an unconditional refund available to the company.
At the same time, the company should not mechanically make a payment without first establishing the correct statutory computation.
The crucial issue is the application of Section 170A.
Where the modified return was filed before the original return was processed, Section 170A(2)(b) becomes particularly relevant. The Assessing Officer is required to determine the income in accordance with the business reorganisation order and take into account the modified return.
The recent Bombay High Court decisions in Bajaj Electricals Limited and Technoforce Solutions (I) Private Limited provide significant judicial support for the proposition that the statutory modified return cannot simply be disregarded while determining the final tax position following a business reorganisation.
Where the original processing does not properly reflect the modified return, Section 154 may provide an appropriate mechanism for rectification, depending upon the facts and whether the error qualifies as a mistake apparent from the record.
Once the final refund is determined, any amount found to have been refunded in excess may become recoverable, and the consequences under Section 234D, including applicable interest, would need to be examined.
The practical lesson for taxpayers undergoing a demerger or amalgamation is therefore clear: filing the Section 170A modified return should not be treated as the end of the compliance exercise. The subsequent processing of the original return, the Section 143(1) intimation, the refund actually received and the eventual tax position after giving effect to the reorganisation must all be reconciled.
A taxpayer who identifies such a mismatch should proactively place the complete chronology before the Department and seek appropriate correction rather than waiting for the excess refund to be converted into a demand with consequential interest.
Section 170A was introduced to bridge precisely this gap between the legal effect of a business reorganisation and the income-tax return already filed before such reorganisation was sanctioned. Its effective implementation therefore requires coordination between the modified return, the assessment mechanism and the consequential refund.
