Form ITR-A under Section 170A enables successor entities to file modified income-tax returns post court-approved mergers, demergers, and reorganisations.
CBDT announced ITR-A for filing returns
Form ITR-A is the dedicated income-tax return form for modified returns filed under Section 170A of the Income-tax Act, 1961. When an NCLT, High Court, or other Adjudicating Authority approves a scheme of merger, demerger, amalgamation, or business succession, the successor entity must file ITR-A within six months of the end of the month in which the order is passed — to recompute income, transfer accumulated losses, and correctly map TDS and MAT credits for every assessment year spanning the scheme's appointed date. Getting this window wrong means tax demands land on a defunct entity with no one to pay them.
What Is Form ITR-A and Why Does It Exist?
Before Finance Act 2022, Indian tax law had no clean mechanism for updating filed returns after a court-approved restructuring. When Company A merged into Company B, the books moved but the tax records stayed frozen in Company A's PAN. Refunds got stuck. Scrutiny notices went to a dead entity. Loss carry-forwards expired before they could be absorbed.
Section 170A, inserted by the Finance Act 2022 with effect from 1 April 2022, closed this gap. It gives the successor entity the right — and the obligation — to file a modified return for every assessment year falling between the scheme's appointed date and the date of the court order. CBDT subsequently notified Form ITR-A as the vehicle for these modified returns.
The practical significance is substantial. Every NCLT-approved merger, IBC resolution plan with tax implications, or High Court-sanctioned demerger now generates a mandatory ITR-A filing calendar. Tax advisors who treat restructuring as a purely M&A or Companies Act exercise — and miss the Section 170A obligation — set their clients up for avoidable demands and forfeited credits.
Who Must File Form ITR-A?
Not every restructuring triggers ITR-A. The Section 170A obligation arises only when all three of these conditions are met simultaneously:
- There is a business reorganisation — meaning a merger, demerger, amalgamation, or business succession involving a transfer of undertaking.
- The reorganisation is approved by a qualifying order — from a court (High Court or Supreme Court), tribunal (NCLT), or other Adjudicating Authority.
- The order affects the tax position of any assessment year straddling the appointed date.
Qualifying schemes and orders
- Schemes under Sections 230 to 232 of the Companies Act, 2013 (amalgamations and arrangements sanctioned by NCLT)
- Resolution plans approved by NCLT under the Insolvency and Bankruptcy Code, 2016, where the plan explicitly alters prior-year tax treatment
- Cooperative banks reorganised under the Banking Regulation Act, 1949 pursuant to an order of the Central Government or RBI acting as Adjudicating Authority
- Schemes sanctioned by the High Court for companies that fall outside NCLT jurisdiction, including older schemes filed before the 2016 Companies Act migration
Who actually files the form
The successor entity files ITR-A under its own PAN. Where the original return was filed by the predecessor, ITR-A carries a cross-reference to the predecessor's PAN and the originally filed return. The predecessor does not file a revised return — the successor's ITR-A supersedes it for the relevant years.
If a single merger involves multiple predecessors (for example, four subsidiaries amalgamated into one holding company), the successor must file a separate ITR-A for each predecessor, for each assessment year that falls within the modification window.
The Six-Month Filing Deadline: How to Count It Correctly
Section 170A(3) sets the clock precisely: six months from the end of the month in which the order is made. This is not six months from the order date — it is six months from the last day of the month that contains the order date.
Example: NCLT passes an order on 14 October 2025.
- The month of the order: October 2025
- End of that month: 31 October 2025
- Six months from 31 October 2025: 30 April 2026
This distinction costs entities that miscalculate. If your advisors count six months from 14 October and target 14 April, they are still within time — but organisations that count six months from 1 October (start of the month) could miss the deadline for schemes where the order was issued early in the month.
Which assessment years need modification?
Modify every AY whose corresponding financial year (or any part of it) falls between the appointed date and the order date. If the appointed date is 1 April 2024 and the NCLT order arrives on 14 October 2025, both AY 2025-26 (FY 2024-25) and AY 2026-27 (FY 2025-26, up to the order date) are in scope.
A scheme with a backdated appointed date of, say, 1 January 2023 but an NCLT order in March 2026 would require ITR-A for AY 2024-25, AY 2025-26, and AY 2026-27 — three separate filings under the successor's PAN.
What Form ITR-A Captures: Schedules and Data Points
Form ITR-A is materially more complex than a standard corporate ITR because it requires a side-by-side reconciliation of the original return and the modified position. The key data points and schedules include:
- Scheme identifiers: Order date, appointed date, name and PAN of each predecessor, court or tribunal that issued the order
- AY being modified: Every modified AY is a separate form filing
- Income head reconciliation: Business income, capital gains, other sources — original figure vs modified figure, with reasons
- Capital gains adjustment under Section 47: Transfer of assets in a qualifying amalgamation or demerger is exempt from capital gains tax; ITR-A must explicitly map the exemption for each asset class
- Loss transfer schedules:
- Section 72A: Carry-forward of business losses of an amalgamating company — available to successor if industrial undertaking conditions are met, including the requirement that the amalgamating company was not formed by splitting up or reconstruction of an existing business
- Section 72AA: Specific loss transfer provisions for amalgamating banking institutions and cooperative banks
- Unabsorbed depreciation under Section 32(2), which transfers without the Section 72A conditions
- MAT credit transfer: Book profit and minimum alternate tax credit accumulated by the predecessor flows to the successor's AY computation
- TDS and advance tax reconciliation: Credits that were posted against the predecessor's PAN must be mapped to the successor — this requires coordination with TRACES and the successor's AO
- Depreciation schedule under Section 32: Opening WDV of block of assets as at the appointed date must be reported in the successor's block
Step-by-Step: Filing ITR-A on the Income Tax Portal
Filing ITR-A is done entirely on the Income Tax Portal (incometax.gov.in). The portal does not currently auto-populate predecessor data, so the preparatory work is almost entirely offline.
Step 1 — Map the scheme documents Obtain a certified copy of the NCLT or court order, the scheme itself, and the auditor's certificate on the appointed date. Confirm the effective date as it appears in the order — courts sometimes approve a scheme with an appointed date that pre-dates the filing.
Step 2 — Pull all originally filed returns Download the filed ITRs of each predecessor for every AY in scope. Cross-check with the AIS (Annual Information Statement) and TIS (Taxpayer Information Summary) of the predecessor PAN to ensure no income line is missed.
Step 3 — Build the modification workpaper Prepare a column-by-column comparison: As originally filed vs As modified under scheme. Document the legal basis for every change — Section 47, 72A, 72AA, 32, or 115JB as relevant. This workpaper becomes the basis for any query from the Assessing Officer.
Step 4 — Reconcile TDS and MAT credit Write to the predecessor's TDS-deductors requesting reissuance of Form 16A/26AS corrections where credits need to shift PAN. Engage with TRACES to ensure TDS credit migration is processed before filing, otherwise the portal will show a mismatch.
Step 5 — File electronically under successor's PAN Login to the Income Tax Portal using the successor entity's PAN and credentials. Navigate to e-File → Income Tax Returns → File Income Tax Return and select the relevant AY. Select Form ITR-A from the form type dropdown. Complete all schedules. Attach the NCLT/court order (PDF, maximum size as prescribed) as a mandatory attachment. E-verify using DSC (preferred for companies) or EVC.
Step 6 — Track the modified assessment After filing, the AO has one year from the end of the month in which the modified return is filed to pass a modified assessment or reassessment order under Section 170A(4). Monitor e-Proceedings on the portal. Respond to any information requests promptly — delays here can trigger Section 144 best-judgment assessment.
Worked Example: Amalgamation with Loss Transfer and TDS Credit Mapping
The facts
TechMerge Solutions Ltd (successor, PAN: AABCT1234X) absorbs DataSoft Pvt Ltd (predecessor, PAN: AAQPD5678Y) via an NCLT-approved amalgamation.
- Appointed date: 1 April 2024
- NCLT order date: 20 August 2025
- End of order month: 31 August 2025
- ITR-A filing deadline: 28 February 2026
Assessment years in scope: AY 2025-26 (FY 2024-25, entire year falls between appointed date and order date).
DataSoft's original AY 2025-26 return (filed July 2025 under AAQPD5678Y)
| Line item | As originally filed |
|---|---|
| Business income | Rs. 1,50,00,000 |
| Brought-forward business loss (AY 2024-25) | Rs. (40,00,000) |
| Net taxable income | Rs. 1,10,00,000 |
| Tax @ 25% (Section 115BA) | Rs. 27,50,000 |
| TDS deducted on DataSoft's receipts | Rs. 9,00,000 |
| Advance tax paid by DataSoft | Rs. 16,00,000 |
| MAT credit b/f | Rs. 6,50,000 |
| Tax payable after TDS/advance tax | Rs. 2,50,000 |
Modified position under ITR-A filed by TechMerge
Capital gains on DataSoft's assets transferred to TechMerge: Nil — exempt under Section 47(vi) as the transfer is in a qualifying amalgamation.
Loss transfer: The Rs. 40,00,000 brought-forward business loss of DataSoft is eligible for carry-forward by TechMerge under Section 72A, provided TechMerge holds at least three-quarters of the book value of DataSoft's assets for five years and continues the business for five years.
TDS credit migration: Rs. 9,00,000 TDS (originally mapped to AAQPD5678Y) must be claimed by TechMerge. This requires a correction statement through TRACES and AO intervention — it does not happen automatically.
MAT credit: Rs. 6,50,000 MAT credit of DataSoft transfers to TechMerge under the scheme.
Tax saving from the Section 72A loss absorption (in TechMerge's own returns): Rs. 40,00,000 × 22% (assuming TechMerge opts for Section 115BAA) = Rs. 8,80,000 in tax saved over the absorption period.
If ITR-A is not filed by 28 February 2026: DataSoft's AY 2025-26 return stands as filed under the defunct PAN. The Rs. 9,00,000 TDS refund (after netting) remains trapped. The Rs. 40,00,000 loss cannot be claimed by TechMerge because the formal modified return mechanism under Section 170A was not invoked. TechMerge faces a reassessment risk under Section 170(2) for income that was earned by DataSoft post appointed-date but not brought into TechMerge's tax records.
Common Pitfalls That Derail ITR-A Filings
1. Confusing the appointed date with the effective date
The appointed date in the scheme document drives the tax modification. If the scheme says "1 April 2024" but the NCLT order is dated "20 August 2025," income from 1 April 2024 belongs to the successor — even though the order came fifteen months later. Using the order date as the tax cutoff is wrong and will produce an incorrect ITR-A.
2. Missing the Section 72A eligibility conditions
Not every amalgamation allows loss transfer. Section 72A requires: (a) the amalgamating company is an Indian company; (b) it was not formed by splitting up or reconstruction; (c) it was in operation for at least three years; (d) the amalgamated company holds at least 75% of the book value of assets for five years; (e) it continues the business for five years. Filing ITR-A and claiming the loss without meeting these conditions will result in disallowance plus interest.
3. Skipping TDS credit reconciliation before filing
TDS credits in the predecessor's Form 26AS do not automatically migrate. If you file ITR-A claiming TDS credits without first getting TRACES corrections done, the AO will raise a demand for the differential. This is the single largest source of post-ITR-A disputes in amalgamation filings.
4. Treating ITR-A as the end of the process
Filing ITR-A starts the clock for the AO's modified assessment under Section 170A(4). It does not close out scrutiny. Pending assessments of the predecessor shift to the successor — including notices already in e-Proceedings. Successors who do not check the predecessor's e-Proceedings portal before and after filing miss live notices that are now their responsibility.
5. Ignoring multi-year schemes
A scheme with an appointed date in FY 2022-23 and an NCLT order in FY 2025-26 requires ITR-A for three or four AYs. Teams that only file for the most recent AY leave earlier years uncorrected — and those earlier years may have the largest loss carry-forwards and MAT credits.
6. Missing GST coordination
Section 18(3) of the CGST Act requires the successor to file a GST ITC-02 to claim the input tax credit balance of the transferor at the time of the appointed-date transfer. The income-tax appointed date and the GST transfer date must align. Misalignment creates scrutiny under both authorities simultaneously.
What Happens After You File: The Modified Assessment Process
Once ITR-A is filed and e-verified, it enters the Assessing Officer's workflow. Under Section 170A(4), the AO must pass a modified assessment or reassessment order within one year from the end of the month in which the modified return is furnished.
The AO may:
- Accept the modified return as filed and issue a modified assessment order reflecting the successor's revised tax position
- Raise queries through e-Proceedings seeking additional documentation on the scheme, asset valuations, or loss eligibility conditions
- Issue a notice under Section 143(2) if the modified return is selected for scrutiny — this is treated procedurally like a scrutiny assessment of a regular return
The key practical point: the AO cannot reopen years covered by ITR-A simply because the original return was filed by a different entity. The filing of ITR-A under Section 170A creates a clean legal basis — the successor owns those years and responds to the modified assessment in its own name.
Track the modified assessment status monthly under e-Proceedings → View Notices / Orders for the successor's PAN. If no order is passed within the one-year window, the modified return as filed is deemed accepted.
Key Takeaways
- Section 170A (effective 1 April 2022) mandates that successors file Form ITR-A within six months from the end of the month of the NCLT/court order — not six months from the order date.
- ITR-A is filed by the successor entity under its own PAN, covers every AY between the appointed date and the order date, and references the predecessor's originally filed returns.
- The form captures capital gains exemptions under Section 47, loss transfers under Sections 72A and 72AA, unabsorbed depreciation, MAT credit, TDS credits, and advance tax — each requiring a separate reconciliation trail.
- Section 72A loss transfers are conditional — industrial undertaking continuity and 75% asset-holding tests apply; claiming them without meeting the conditions creates disallowance risk.
- TDS credit migration from the predecessor's PAN to the successor's PAN requires proactive TRACES correction before filing ITR-A — it does not happen automatically.
- Failing to file ITR-A locks refunds in the defunct predecessor's PAN, forfeits the right to formally carry forward losses, and exposes the successor to assessment under Section 170(2).
- Build the ITR-A calendar on Day One of the restructuring process, not after the NCLT order arrives — the workpapers for three or four AYs take weeks to compile correctly.
