(Being recognition of estimated deferred tax liability under Ind AS 12 / AS 22 due to accelerated tax depreciation)
Ind AS 12 (Balance Sheet Approach)

Under Ind AS 12, deferred tax is recognized on temporary differences between the carrying amount of an asset in the balance sheet and its tax base. Future reversals dictate DTL or DTA.

AS 22 (Timing Difference Approach)

Under AS 22, deferred tax is accounted for timing differences between taxable income and accounting income that originate in one period and are capable of reversal in subsequent periods.

Statutory Caveat: Actual balance sheet recognition of Deferred Tax Assets requires management to assess reasonable/virtual certainty of future taxable profit at the time of reversal under Ind AS 12 / AS 22. Current effective rate: 25.168%.
