MAT and AMT Credit Under Income-tax Act, 2025: Transition Guide
A business guide to reviewing MAT and AMT credit balances, old computations, and new-law transition records.
Companies and LLPs that have accumulated MAT or AMT credit over previous years face a specific housekeeping task now that the Income-tax Act, 2025 and Finance Act 2025 have come into force. These credits are long-tail records — they originate in one assessment year, get utilised partially over subsequent years, and their balances depend on the accuracy of earlier returns and assessment orders. The transition to the new law makes it more important, not less, to get this reconciliation right before the next filing cycle begins.
This guide is an educational readiness note for Indian taxpayers, founders, and finance teams. It is not a promise of any particular tax outcome or notice avoidance, and it should not be treated as a substitute for a CA-reviewed filing position.
What changes and what needs attention
MAT credit (Minimum Alternate Tax) and AMT credit (Alternate Minimum Tax) represent taxes paid above the regular liability in earlier years, available for set-off when regular tax exceeds MAT or AMT in a later year. Managing these credits requires tracking origin year, utilisation, remaining balance, and any changes arising from assessments or appeals.
| Point | Practical meaning |
|---|---|
| 1 | MAT and AMT credit balances should be reconciled before new-period filing. |
| 2 | Old computations and assessment orders remain important evidence. |
| 3 | Finance teams should maintain a credit movement schedule. |
Why the transition creates a timing challenge
The Income-tax Act, 2025 introduces the concept of Tax Year, which sits alongside the familiar Assessment Year terminology still applicable to AY 2026-27 returns covering FY 2025-26 income. In the same month, a company's finance team can be handling AY 2026-27 return preparation under the Income Tax Act, 1961 framework, Tax Year 2026-27 advance-tax calculations under the new law, older assessment notices, and revised forms — all at once.
A clean file separates these streams clearly. Each item in the compliance calendar should show the relevant period, the applicable law, the portal form, the payment or return type, and the supporting documents. Blending Tax Year 2026-27 payment records with AY 2026-27 return records is a common source of errors in exactly this kind of transitional year.
A practical illustration
Consider a company that paid MAT in AY 2022-23 and has been carrying forward a credit balance since then. Before relying on that balance in the AY 2026-27 return, the finance team should pull together the audited financial statements for each relevant year, the MAT computation from the earlier returns, any assessment orders that revised the credit position, and the current tax computation. If those four elements tell a consistent story, the credit can be used with confidence. If they diverge — different credit amounts in different documents — the discrepancy needs to be resolved before the return is filed.
Records to keep
- MAT/AMT credit movement schedule (origin year, utilisation by year, remaining balance)
- Earlier tax returns showing MAT or AMT credit claims
- Assessment orders that may have revised those claims
- Audited financial statements for each relevant period
Step-by-step checklist
- Identify whether the MAT and AMT credit review affects AY 2026-27 filing, Tax Year 2026-27 compliance, or both.
- Read the official source and map the applicable provisions to the taxpayer type, income head, and relevant dates.
- Collect source records, computation notes, challans, statements, and declarations before filing or making payments.
- Check whether the credit utilisation changes the ITR form, relevant schedule, tax payment amount, TDS/TCS treatment, or disclosure requirement.
- After submission, preserve the final return, acknowledgement, e-verification proof, and the supporting working papers.

Mistakes that create problems later
- Using a familiar old form number without verifying whether the current official form has changed.
- Mixing AY 2026-27 filing records with Tax Year 2026-27 payment or TDS records in the same folder or computation.
- Treating a headline slab, rebate, or threshold as the final tax figure without running the full computation.
- Filing or making payments before reconciling AIS, Form 26AS, challans, books, and certificates.
- Not preserving the official source and computation note that justified the position taken.
How MyeCA helps
MyeCA helps businesses organise records, compare filing routes, prepare document checklists, review tax-credit mismatches, and identify when a CA-led review adds value before filing or responding to a notice. The goal is readiness — ensuring that when the return or payment is due, the underlying file is already in order.
Final checklist
Confirm the relevant year and applicable law. Read the official source and map the rule to the specific facts. Collect supporting records and prepare a short computation note. Verify the return or payment route before proceeding. After submission, preserve the acknowledgement, e-verification proof, and working papers in a single retrievable folder.
