MAT Computation for Ind AS Companies – OCI | Transition Adjustments | Book Profit

Editorial Team – [2026] 186 taxmann.com 499 (Article)

1. Introduction

The implementation of Indian Accounting Standards (Ind AS) significantly changed the manner in which companies prepare and present financial statements in India. Unlike the earlier Accounting Standards framework, Ind AS introduced concepts such as fair valuation, Other Comprehensive Income (OCI), hedge accounting, revaluation adjustments and transition accounting.

While these accounting changes improved transparency and global comparability, they also created practical challenges in the computation of Minimum Alternate Tax (MAT). This is because MAT is levied on the “book profit” of a company, and under Ind AS, several gains and losses are recognised outside the traditional Statement of Profit and Loss.

To address this issue, special provisions were introduced to govern the computation of MAT in case of Ind AS-compliant companies. The intention behind these provisions was to ensure that unrealised and notional accounting adjustments do not result in artificial MAT liability merely because of accounting presentation requirements under Ind AS.

This article explains the MAT framework applicable to Ind AS-compliant companies in a simplified and practical manner with illustrations and numerical scenarios.

2. Understanding MAT Under the Income Tax Framework

Minimum Alternate Tax is designed to ensure that companies reporting substantial accounting profits also pay a minimum level of tax, even if taxable income under normal provisions is low because of exemptions, deductions or incentives. Accordingly, companies are required to pay tax either under the normal computation mechanism or on “book profit”, whichever is higher.

Therefore, the concept of “book profit” assumes significant importance. Under the traditional accounting framework, book profit was derived largely from the net profit disclosed in the Statement of Profit and Loss, subject to specified additions and deductions. However, the position became more complicated after the implementation of Ind AS because several gains and losses started getting recognised through Other Comprehensive Income instead of profit or loss.

As a result, special MAT adjustments became necessary in order to appropriately capture the impact of Ind AS accounting.

3. Concept of Other Comprehensive Income (OCI)

Under Ind AS, the financial performance of a company is no longer restricted only to the profit or loss reported in the Statement of Profit and Loss. Companies are also required to present “Other Comprehensive Income” which includes specified gains and losses recognised directly in equity instead of profit or loss. The aggregate of profit or loss and OCI is presented as “Total Comprehensive Income”.

OCI generally contains unrealised gains and losses arising from fair valuation or re-measurement exercises. Common examples include revaluation gains on property, plant and equipment, actuarial gains and losses on defined benefit obligations, fair value changes in investments classified as FVTOCI, foreign currency translation adjustments and certain hedge accounting reserves.

For MAT purposes, the treatment of OCI items depends upon whether such items will subsequently be reclassified to profit or loss or whether they will permanently remain outside the Statement of Profit and Loss. This distinction becomes extremely important while computing book profit.

4. Understanding the Calculation of Book Profit

Minimum Alternative Tax (MAT) is computed on the book profit of a company. Book profit means net profit as shown in the statement of profit & loss, as increased and decreased by certain specified items. So, the first and most important step while calculating MAT is to compute the book profit.

The CBDT has issued a circular stating that the book profit of Ind-AS-compliant companies should be calculated based on the book profit computed as per the existing provisions of Section 206, which shall be further:

a) Increased by amounts of OCI items credited to other comprehensive income in the statement of profit & loss under the head ‘Items that will not be re-classified to profit or loss’

b) Decreased by amounts of OCI items debited to other comprehensive income in the statement of profit & loss under the head ‘Items that will not be re-classified to profit or loss’

c) Increased by the amount debited to the statement of profit & loss on distribution of non-cash assets to shareholders in a demerger in accordance with Appendix A of Ind AS 10 (Events after the Reporting Period)

d) Decreased by the amount credited to the statement of profit & loss on distribution of non-cash assets to shareholders in a demerger in accordance with Appendix A of Ind AS 10 (Events after the Reporting Period).
