Minimum Alternate Tax (MAT) for Companies Under Income Tax Act 2025: A Complete Legal Analysis
The Income Tax Act 2025 carries forward the fundamental framework of Minimum Alternate Tax that existed under Section 115JB of the Income Tax Act 1961, while introducing updated provisions under Section 206. Just as companies previously had the choice between the regular computation method and the alternate minimum tax regime, the new legislation preserves this structure, allowing companies to evaluate their tax liability under either the regular method or the New Tax Regime under Section 206.
This guide provides a detailed examination of every critical aspect of MAT as applicable to companies under the Income Tax Act 2025.
1. Understanding MAT — Concept, Purpose, and Applicability
What Does MAT Mean and When Does It Trigger?
Minimum Alternate Tax is a mechanism designed to ensure that companies — regardless of the scale of deductions, exemptions, or incentives they claim under normal provisions — contribute a baseline level of tax to the exchequer.
The triggering condition is straightforward:
Where the income tax payable on Total Income computed under normal provisions of the Act is lower than the MAT computed on Book Profit, the Book Profit shall be deemed to be the Total Income of the company, and the company shall be liable to pay income tax equal to such MAT.
In practical terms, MAT functions as a floor on corporate tax liability — no company can reduce its effective tax burden below a defined minimum threshold simply by availing of available deductions.
Illustrative Example
| Particulars | Amount (Rs. in Crores) |
|---|---|
| Total Income under Normal Provisions | 75.00 |
Tax @ 29.12% (assuming Section 200 not opted) (A) |
21.84 |
Book Profit under Section 206 |
250.00 |
| MAT @ 14% + 12% Surcharge + 4% Cess (effective ~16.16%) (B) | 40.40 |
| Tax Payable (Higher of A or B) | 40.40 |
In this scenario, since MAT (B) exceeds the normal tax (A), the company discharges its liability at the MAT rate.
2. Applicable MAT Rates Under Section 206(1)(b) for Tax Year 2026-27
The base MAT rates prescribed under Section 206(1)(b) for the Tax Year 2026-27 are as follows:
| Category of Company | MAT Rate |
|---|---|
| Company being a unit in International Financial Services Centre (IFSC) deriving income solely in convertible foreign exchange | 9% |
| Any other Company | 14% |
Important: These are base rates only. Applicable Surcharge and Health & Education Cess (currently 4%) as notified by the Finance Act for the relevant Tax Year must be added to arrive at the effective MAT rate.
3. Defining "Book Profit" Under Section 206(1)(c)
Book Profit for MAT purposes refers to the Net Profit as reflected in the Statement of Profit & Loss for the relevant Tax Year, prepared in accordance with Section 206(1)(f), after incorporating the following mandatory adjustments:
Additions to Net Profit
| S.No. | Item | Condition |
|---|---|---|
| (i) | Income tax paid/payable and provisions therefor (including surcharge, interest, cess) | If debited to P&L |
| (ii) | Amounts transferred to any Reserve (by whatever name called) | If debited to P&L |
| (iii) | Provisions for liabilities other than ascertained liabilities | If debited to P&L |
| (iv) | Provisions for losses of subsidiary companies | If debited to P&L |
| (v) | Dividends paid or proposed | If debited to P&L |
| (vi) | Expenditure relatable to exempt income under Section 11 |
If debited to P&L |
| (vii) | Depreciation | If debited to P&L |
| (viii) | Deferred tax and provision therefor | If debited to P&L |
| (ix) | Provision for diminution in value of any asset | If debited to P&L |
| (x) | Amount standing in Revaluation Reserve on retirement or disposal of a revalued asset | If not credited to P&L |
Deductions from Net Profit
| S.No. | Item | Condition |
|---|---|---|
| (xi) | Amounts withdrawn from any Reserve or Provision (post 1st April 1997) | If credited to P&L AND book profit was earlier increased by such reserve |
| (xii) | Income to which Section 11 applies |
If credited to P&L |
| (xiii) | Depreciation debited to P&L | Excluding depreciation on revalued assets |
| (xiv) | Amounts withdrawn from Revaluation Reserve | To the extent it does not exceed depreciation on revalued assets |
| (xv) | Deferred tax | If credited to P&L |
| (xvi) | Lower of: loss brought forward (excluding depreciation) OR unabsorbed depreciation as per books | Except where either figure is NIL; not applicable to companies under Section 206(1)(d)(vi) & (vii) |
4. Preparation of Statement of Profit & Loss for MAT — Section 206(1)(f)
The framework applicable to a company for preparing its Statement of Profit & Loss for MAT computation depends on the nature of the company:
| Category | Applicable Framework |
|---|---|
| Insurance Company | As per Insurance Act / IRDA regulations |
| Banking Company | As per Banking Regulation Act |
| Electricity Generation/Supply Company | As per Electricity Act |
| Any other class of company with a specified form under its governing enactment | As per such enactment |
| All other Companies | As per Schedule III to the Companies Act, 2013 |
**Critical Note — Section 206(1)(g)😗* The accounting policies, accounting standards, and depreciation rates used for MAT computation must be identical to those adopted for preparing the accounts placed before the Annual General Meeting under
Section 129of the Companies Act, 2013. A company cannot adopt a separate or different set of accounting policies exclusively for MAT computation.
5. Special Adjustments for Ind AS Companies — Section 206(1)(d)(ix)
Companies that follow Indian Accounting Standards (Ind AS) are required to make the following additional adjustments to Book Profit:
| S.No. | Amounts to be Added (Column A) | Amounts to be Reduced (Column B) |
|---|---|---|
| 1 | Other Comprehensive Income (OCI) items not re-classified to P&L (excluding revaluation surplus & FVOCI equity instruments) credited to P&L | OCI items debited to P&L |
| 2 | Amounts debited to P&L on distribution of non-cash assets to shareholders in a demerger (Appendix A of Ind AS 10) | Amounts credited to P&L on such distribution |
| 3 | 1/5th of Transition Amount in the year of convergence and in each of the subsequent 4 Tax Years | 1/5th of Transition Amount in the year of convergence and in each of the subsequent 4 Tax Years |
| 4 | Amounts relatable to specific assets/investments under Section 206(1)(e)(iii) if not decreased |
Same if not increased |
| 5 | Amounts relatable to foreign operations under Section 206(1)(e)(iv) if not decreased |
